A comparison of Value at Risk approaches

Patrycja Odyniec1,*

1 Bialystok University of Technology, Faculty of Computer Science, Department of Applied Mathematics, Białystok, Poland

Keywords: risk, comparison, backtesting, holding period, confidence level

In the financial world, risk management is the process of identification, analysis and acceptance or mitigation of uncertainty in investment decisions. For investors, risk is about the odds of losing money. It is very important to have the knowledge of the instruments which are worth to invest in, but even more important is to know how to deal with risk which appears always with financial investments. One of the most widely used risk measures in financial institutions is Value at Risk (VaR), developed by J.P. Morgan in the 1990s. VaR is used to summarize the predicted maximum loss (or worst loss) over a target horizon within a given confidence level. The aim of this presentation is to provide an introduction to three basic approaches to VaR: Historical Method, The Variance-Covariance Method and Monte Carlo Simulation and to present a comparison of them based on the selected investment portfolio from Warsaw Stock Exchange. Value at Risk was calculated with confidence levels of 95% and 99%, where the holding periods were: 1 day, 7 days and 30 days. Finally, the accuracy of each method was measured using backtesting analysis.

A huge effort to study tiny dispersers

Anna Radwańska1,*, Kamila Karpicka-Ignatowska1, Agnieszka Majer1, Alicja Laska1

1 Population Ecology Lab, Faculty of Biology, Adam Mickiewicz University, Poznań, Poland

Keywords: phytophagous mites, wind dispersal, colonisation potential

Dispersal is an ecological process that involves the movement of individuals in order to colonise new sites in which they settle down and reproduce. The entire process includes three stages: departure, transfer and settlement. Dispersal can lead to gene flow within and between populations, having a great impact on individual fitness and population structure. Investigation of dispersal ability can be challenging and requires a lot of effort, but it is particularly important in case of invasive species - such as phytophagous mites - as it can cause great economic impact. These invertebrate animals favourably choose wind currents for their long-distance journeys. Using a mite Aceria tosichella (Eriophyoidea) as an a study subject, we have devised protocols for measuring dispersal, taking into account its complexity and particular stages: (i) dispersal propensity: expressed as the number of individuals displaying behaviours that increase the probability of being blown in the presence of wind; (ii) dispersal efficiency: expressed as the number of individuals that successfully disperse to a new plant; and (iii) colonisation potential: characterised by the population growth rate, (the intensity of increasing population density) on freshly colonised plants. We, ourselves, constructed wind tunnels generating stable wind speeds between 0.2-5.7 m/s, with test speeds approximately every 0.2 m/s. Aerial dispersal was induced by short or long-blowing sessions. During short-blowing sessions videos were recorded to analyse dispersal propensity expressed by specific behaviours. Surveys examining dispersal process including its three phases (departure, transfer, and settlement) require interdisciplinary knowledge and a great deal of work. Nevertheless, measuring dispersal traits in invasive herbivores may help to control their possible outbreaks and to develop effective management strategies.

A thermal imaging analysis of temperature distribution on the human skin during strength training exercises

Jarosław Zubrzycki1,*, Magdalena Marchewka1, Patryk Szymaniak1

1 Lublin University of Technology, Mechanical Engineering Faculty, Department of Biomedical Engineering, Lublin, Poland

Keywords: thermography, radiation, infrared camera, sports medicine

Motivation for this paper was to show new possibilities of non-invasive examination of body changes - thermography. It has been proved that the infrared camera can be used in sports medicine and this paper shows how the infrared camera can be used in everyday body examination.

The most important are its non-invasiveness, painlessness and discomfort-free nature. The full body thermography scan represents the distribution of the temperature on the body surface. It can be also used to lower the body temperature due to impaired blood flow. What is more this method is perfect because it does not affect the emission of infrared radiation based on the skin pigmentation. It also does not matter whether the measurements are made in the dark or in visible light. The skin of the patient should not be covered during the test and the skin surface should be cleaned with alcohol in order to remove impurities. Measurement should be performed from 1 meter distance.

The paper include simple experiment made on a 22 years old man. The patient did three exercises namely: push-ups, sit-ups and French Press. The experiment was made on the infrared camera model B365. The popular 'push-ups' target mainly the muscles of the upper chest and deltoid muscles. The thermographs show that to achieve the desired effect of muscle fatigue one has to do more than 1–2 series of exercises. Second exercise shows that the adipose tissue significantly affects the temperature distribution on the surface of the human body. The thickness of fat tissue between the skin and abdominal muscles is greater than between the skin and the oblique muscles of the abdomen – hence the large discrepancies between temperature differences during this exercise. The thermographs of lying French press dumbbell triceps extension exercises show differences between temperature distribution on the skin of the left and right elbow. This reflects the greater loading of the right arm.

Summarizing, the infrared camera can be used to observe the work of the circulatory system and the active parts of the musculoskeletal system. Thermal imaging can also be applied in detecting changes in the peripheral blood vessels of the lower and upper limbs.

Activity measurements of radionuclides in fly-ashes from combustion of solid fuels in conventional power plants

Anna Kawalec1,*, Paweł Gajda2, Paweł Jodłowski3

Energy, Krakow, Poland 3 AGH University of Science and Technology, Faculty of Physics and Applied Computer Science,

Krakow, Poland

Keywords: fly-ash, radionuclides, gamma-ray spectrometry

The current electricity and heat generation in Poland is predominantly based on the use of hard coal and lignite. It contributes to production of huge amounts of combustion by-products including fly-ash.

The main objective of the presented project is dosimetrical analysis of fly-ash from coal combustion with or without additive of other co-combustion materials, such as biomass. One of the motivations of the study is to determine how those radionuclides could affect human health and possible further use of the fly-ashes, for example in construction materials fabrication. Collected samples were divided according to combustion fuel as well as sectors of electrostatic precipitators (ESP) they were collected form.

Samples have been analysed by gamma-ray spectrometry to identify and determine concentration of natural radionuclides, such as K-40, Ra-226 and Th-228. It was done with the use of Canberra GX4020- a cylindrical semiconductor detector HPGe (High Purity Germanium). Each sample was put in a tight container for a period of at least 21 days. After this time, the sample was placed directly on the detector and then has been tested. On the basis of the results, proper coefficients were determined to qualify whether studied samples of fly-ash could be used in production of building materials.

Obtained results indicate that natural radionuclides can be found in tested fly-ash samples. For example average uranium content was around 200 ppm. Moreover, there is a relation between radionuclides concentration and fly-ash granulation. Furthermore, in some cases determined coefficients exceed the limit values for construction materials.

AGH Solar Boat - construction of novel, solar powered racing boat

Monika Wolny1, Maciej Borowicz1, Jakub Wiercioch1, Karolina Stuchły1, Monika Jawańska1, Katarzyna Ungeheuer1, Krzysztof Sornek1,*

1 AGH University of Science and Technology, AGH Solar Boat Project, Krakow, Poland

Keywords: AGH Solar Boat, electromobility, electrically driven boat

Electrically driven vehicles, planes and boats may be considered as a solution for the future road, air and water transportation sectors (including autonomous units powered by electricity generated in renewable energy sources). An example of autonomous boat is “Baśka” – solar powered boat developed by students from AGH University of Science and Technology in Krakow.

AGH Solar Boat is a project aimed at construction of novel, solar powered racing boat. It links sustainable development with innovative technologies and represents various aspects of engineering: from construction and material engineering to electronics and photovoltaics.

This paper shows the main aspects of developing the boat, including: (a) modelling of the hull, (b) analysis of introducing such innovations, as hydrofoils, (c) selection and formation of the lightweight and durable materials, (d) selection of the electrical engine, and (e) selection of the photovoltaic modules.

Results of the currently conducted study show important aspects of operation of the solar powered boat – both from the standpoint of power generation and its consumption during races and from the standpoint of reduction of CO2 emission.

Analysis of the composite strain condition on the example of a boat deck

Igor Łukasiewicz1,*

1 AGH University, Faculty of Robotics and Mechanical Engineering, Mechanics and Machine Construction, Krakow, Poland

Keywords: composites, mechanical, analysis, solar, boat.

This analysis was created in Ansys Composite PrepPost and Ansys Mechanical as a result of real damage to the front part of the deck made of structural composite. Deformation of the element as well as distributions of directional stresses were investigated. The values of stress coefficients were determined, on which, as it turned out, the hole made for the photovoltaic module has the greatest influence. The modeled strain reflected very well the to actual (which was presented in this work) and allowed for precise determination of the cause of the damage [1].

Construction of AGH Solar Boat The whole project of the solar boat was made by students of AGH University of Science

and Technology in Krakow in accordance with the requirements of the Monaco Solar Boat

Challenge competition rules, which leaves no room for free interpretation. Both the deck and

the hull were made of CFRP type composite in order to obtain the lowest possible weight of

the structure [2]. The durable, V-shaped hull provides low resistance when sailing in half-

slippery conditions. The entire deck surface is covered with photovoltaic modules, which are

capable of generating 1 kW of power. Under the surface of the water there are hydro-wings,

which generate additional carrying power allowing the boat to leave the water at a speed of

4 m/s.

Analysis of the shielding failure and backflash over in high voltage overhead power lines

Anna Sosna1,*, Mariusz Benesz1

1 AGH University of Science and Technology, Faculty of Electrical Engineering, Automatics, Computer Science and Biomedical Engineering, Department of Electrical Engineering and Power Engineering, Krakow, Poland

Keywords: shielding failure, backflash over, lightning, EMTP-ATP

The reliability of electrical power transmission and distribution systems depends on progress in the coordination of insulation, which depends, among other things, on increasing the ability to identify risks of overvoltage in insulation systems.

The purpose of the paper is to present the problems related to the voltage stresses (overvoltages) of the power system caused by atmospheric discharges (lightning). The article analyses two possible scenarios of sources of these disturbance: shielding failure and backflash over phenomena. In the first scenario, despite the use of ground wire above the phase conductors, a phase conductor is struck directly by lightning. In the second scenario lightning strikes a support structure or ground wire. It causes arising of voltage on the support structure which exceeds lightning impulse withstand the level of the phase insulators and a backflash over occurs.

The result of the work is the determination of characteristic peak values of lightning current: Imax and Imin - respectively for scenario of shielding failure and backflash over phenomena. Between the Imax and Imin values, we have lightning protection (lightning strikes to ground wire). Calculation were carried out on selected profiles of support structures, dedicated to electrical power system with rated voltage of 110 kV, 220 kV and 400 kV (single-circuit and double-circuit three phase line were considered). All simulation cases were performed using The Electromagnetic Transients Program - Alternative Transients Program (EMTP-ATP) and Matlab.

Keywords: angiogenesis, hydroxytyrosol, anti-tumoral therapy

Angiogenesis, a process which allows the formation of new vessels came from pre-existing ones, is an essential phenomenon for tumour survival since it allows cancer cells to obtain nutrients and oxygen. This explains the increasing interest showed by many groups of research and pharmaceutical companies to find compounds with potential to disrupt at least one of the steps within the angiogenic process. Hydroxytyrosol (3,4-dihydroxyphenyl ethanol) has been identified as the most important health-related phenolic compound of virgin olive oil [1] because of its pleiotropic effects on multiple targets. In 2012, hydroxytyrosol was shown to be an anti-angiogenic compound able to inhibit several key steps in the angiogenic process, both in vitro and in vivo [2]. In the present study, the potential effects of six hydroxytyrosol derivatives are tested by several laboratory techniques, showing interesting results. The future aim of this study is to continue with the development of several of these compounds and to test them in clinical trials to discover new anti-angiogenic and anti-tumoral therapies.

Keywords: glassy carbon electrode, metol, voltammetry

p-Methylaminophenol sulphate (metol) is a compound largely used in photographic industry as a reducing agent. Unfortunatelly, metol also has been shown to be toxic and cause health problems [1]. Therefore, the development of sensitive methods for the detection of metol is very necessary. Until now, various method such as spectrophotometry, oscillopolarographic titration, liquid chromatography–mass spectrometry, ceric oxidimetry, and electroanalysis have been developed for determine metol. Among them, the electrochemical methods offer simplicity, selectivity, and rapid response with a long linear dynamic range [2].

Titanium dioxide due to its good electrical properties and high photocatalytic activity is commonly used in many branches of knowledge. In this work application of titanium oxide nanoparticles (P25) has shown in modification of glassy carbon (GC) electrodes often used as a working electrode in voltammetry. This an analytical technique is based on the measurement depending on the current – electric potential in a working and reference electrode immersed in supporting electrolyte with determined analyte.

The GC electrode was modified by conductive layer composed of conducting polymer (PEDOT) and titanium dioxide nanoparticles (P25) using electropolymerization method. Before electropolymerization process GC electrode was polished on the polishing cloth with alumina nanopowder and washed by deionized water and the solution of PEDOT and TiO2 nanoparticles (P25) was mixed by magnetic stirrer.

Preliminary measurements suggest that modification based on PEDOT-TiO2 composite affects the quality of the analytical signal of determined substance. This modification increased the sensitivity of the GC electrode due to metol.

Keywords: Biodiesel, Purification, Adsorbent, Rice Husk

Biodiesel purification can be done with water (wet washing) or without (dry washing). The latter, by its time, uses specific materials that have the capacity to adsorb impurities such as magnesium silicate, anionic and cationic exchange resins, silica, activated carbon, zeolites, bentonitic and smectitic clays and diatomite [1, 2]. The main objective of this work is to investigate the adsorptive capacity of rice husk (RH), propose a low-cost material as adsorbent and an alternative to the purification of biodiesel. To do this, a transesterification reaction of soybean oil was carried for 1 h at 40 °C with methanol (ratio of 1:6 to oil) and 1 % wt. of KOH. The RH experiments were carried out under different conditions (in natura and washed). Samples treated with acid solutions of different concentrations (2 and 4 N) were prepared with sulfuric and hydrochloric acids. For each sample a different interaction time with the acid was set: 1, 2 or 4 hours [3, 4, 5]. Each RH sample was washed with distilled water, vacuum filtered and dried at 102 °C. In addition, two samples of washed RH with 10 % wt. and one sample of purified using water were done. Finally, standardized experiments were done in a flat-bottom flask: 40 grams of biodiesel and 5 % of RH for 10 min. at room temperature. The following physicochemical properties were analyzed (in duplicate): specific gravity (SG) and kinematic viscosity (KV), acidity (AI), free (FAI), combined (CAI) and total alkalinity (TAI) indexes, and free glycerol (GL), all with limits established by a ANP resolution [6]. The use of RH as adsorbent without acid treatment is quite efficient and can favor to reduce the usage of water. RH does not adversely affect the properties of biodiesel, remove FG and reduce levels of FAI, CAI and TAI, all via adsorption. Moreover, RH treated with 4N sulfuric acid for two hours (5 % wt.) showed better results than others, indicating that the treatment may contribute to reductions in the utilized volume.

Keywords: cement mortars, metakaolin, high impact polystyrene

Production of buildings materials associates with high energy consumption. For the sake of the natural environment, the known components of buildings material can be replaced with the other ones which process of manufacturing is less harmful. This paper presents effect of regrind high impact polystyrene (HIPS) and metakaolin on the physico-mechanical properties of cement. Have focused on attention on reduction the amount of cement, partly replacing by metakaolinite. High impact polystyrene was recycled. The use of waste additives is part of sustainable development strategy. Samples were prepared using additives in amount of 5, 10, 15% of cement mass, in order to optimize effects of modification cement mortar. The results of compression strength indicate addition 10% of metakaolinite and 5% of HIPS causes the greatest strength. The tests show that the addition up to 10% metakaolinite has positive effect on strength of cement mortar. More than 10% decrease workability and requires the application of extra amount of batched water and also admixtures. Compression strength decreases with increasing amount of HIPS. Optimal dosage is addition 4-5% of regrind. In summary the results of this study indicate that is possible to obtain parameters of modified mortars very similar to the parameters of a standard mortar, limiting the use of components harmful to the natural environment.

Atmospheric aerosols constitute a complex mixture of organic and inorganic compounds and biological materials. Over the last few decades a concern over the health effects associated with air pollution was growing. Long and frequent exposure of organism to polluted air and inhalation of ambient particles may lead to the loss of the ability for the removal of heavy metals and other toxic substances from the respiratory tract what the antioxidants are responsible for. This may lead to the various diseases and other organism handicaps development [1]. Particulate matter are emitted during numerous combustion processes, mostly forced by anthropogenic activities like various transportations using gasoline and diesel engines or fossil fuels combustion processes. Residential heating systems as wood-like biomass, coal utilizing and incineration of solid waste were researched as well.

The aim of the study was determination of chemical composition of atmospheric aerosols collected in Krakow agglomeration. Samples were collected from Feb. 2017 to Oct. 2017 in Skala and from Dec. 2016 to Jan. 2017 in Wadowice. All samples are quartz fibre filters and represent PM10 fraction collected with 24 h resolution. The analytical work comprised thermo-optical carbon analysis (Sunset OCEC Lab Analyser), determination of major inorganic ions by means of ion chromatography (ICS 3000, Dionex) and determinations of PAHs, bisphenol A (BPA), and further phenols by means of GCMS (Thermo Scientific).

Comparison of empirical methods based on well logging to calculate the total organic carbon content in Baltic basin’s shale gas reservoir

Sebastian Waszkiewicz1,*

Keywords: total organic carbon, shale gas reservoir, Baltic basin

Calculations of total organic carbon (TOC) is one of most important part of interpretation in shale gas reservoirs and it is used to mark the perspective zones. Laboratory methods to measure total organic carbon, for example Rock-Eval pyrolysis, despite the high precision of measurement are only point data. Increase of the sample number causes a significant increase in cost of surveys, making them unprofitable. This article compares the selected methods of total organic carbon determination based on well logging data, what allows to calculate TOC in all measured interval, without increases in financial expenses. The analysis was carried out on two wells located within Peri-Baltic Syneclise and Łeba Elevation being a structural part of the East European platform. Laboratory analyses showed that the most perspective gas-bearing sediments of this area are Silurian and Ordovician shales. Well data from this area was well recognized, but credible determination of TOC is still problematic, because of different conditions (burial depth, temperature, pressure) of hydrocarbons generation and accumulation. In order to estimate TOC, different mathematical equations were compared, such as implemented in TOC application in GeoWin system, based on Passey and Schmoker methods and other empirical equations, which factors were calculated using multidimensional statistical analysis and well logs like gamma ray, bulk density and others.

Keywords: pipeline validation, exploration, video capture

Manufacturing of ventilation systems is a complicated process, which requires to connect many singular parts with different shapes. It is important to perform a verification step of the final product to minimize the risk of failure due to leaks. Usually, the only method which is used to detect defects between connected segments in the pipeline is visual testing of the surface. In this method some of the leaks could be overlooked and will result in the production of a defective pipeline. The solution of this problem may be introduction of dedicated device which is able to enter the pipes and collect information from the inner surface.

Presented problem was motivation of this work to construct the robot for exploring pipelines and transmit information about the surface condition in the real-time. The main task of the device is to move inside the pipeline and send images to the person responsible for checking the system's tightness. The robot construction is based on Arduino [1] system, which is responsible for cooperation of many elements of the robot. In proposed solution the camera attached to two servo mechanisms was used, signal transmitter to send video in the real-time, motors allowing to move around and radio control receiver.

In this work implementation details of the prototype solution was presented. Many tests of the robot during pipelines exploration led to recognize some problems of the proposed solution and finally to make improvements, what is also presented and discussed in this work.

Keywords: wireless, power transfer, air coils, resonance

In recent days, a systematic growth in electric cars production can be observed. Usability of electrical cars is strongly related with charging station network which provide mostly conventional charging by cable conductor. More and more focus is oriented at wireless transmission [1] of electrical power which simplifies charging process and can be used automatically. One of most developed types of wireless power chargers are induction type, which transfers electrical energy contactless via electromagnetic coupling between circuits in electric resonance state [1,2]. From the user’s point of view the most important parameters are their efficiency and time to full battery charge. This two parameters are strongly related with placement of transmitting and receiving coil and the construction of whole wireless transmission system especially Q-factor of coils, resonant frequency and materials used for construction [2].

The article presents efficiency analysis of created test model which consists of two air coils, voltage supply and resistive load. Analysis is performed in relation to the coil’s design (round coils and square type coils), the configuration of the system and placement of coils (impact of horizontal and vertical distance between coils and angle).

Keywords: machine learning, neural networks, prediction, classification

With technological progress and increase in computing power available, an advancement in modelling and automatization of actions performed by humans was observed. One of methods used for those tasks are artificial neural models, which are mathematical models inspired by human nervous system. Their advantage is the ability to process multidimensional, big datasets without defined dependencies between the input variables. It is possible thanks to their main idea, which is simulating intelligence and ability to learn.

Artificial neural networks are able to find mentioned dependencies between the variables and determine how much they influence the desired output which motivated the authors to share their results and popularize the concept of convolutional neural networks.

This paper’s goal is to present the principles of convolutional neural networks through short theoretical introduction involving convolution operation and the way of creating architectures, followed by the description of solving selected practical issues from the scope of prediction and classification problem, including the results analysis. Every dataset used was split into the training dataset and testing dataset in order to validate the quality of created models.

Convolutional neural networks are at the moment outclassing every other model in terms of the image classification task and, as shown in paper, are competitive in solving regression problems.

Correction of shoulder bed effect by globally optimized inversion of well logs

Keywords: well logging, thin-beds problem, iterative inversion, global optimization,

simulated annealing.

In thinly-bedded reservoirs vertical range of logging tools investigation volume is usually larger than the thickness of individual thin beds. Therefore, standard logging tools generally do not allow the direct measurement of the physical properties of individual thin beds and in some cases even cannot detect of the beds themselves.

In Poland thin-bed problem exists in the sandy-shaly Miocene formation of the Carpathian Foredeep, one of the most important petroleum provinces in Poland. In this formation masking effect of high resistivity, which is the result of the low vertical resolution of induction tools, is the main source of errors in gas saturation evaluation. Two induction tools used almost exclusively in the Carpathian Foredeep are Dual Induction Tool (DIT) and High Resolution Induction Array (HRAI) tool. The vertical resolution of logs provided by DIT is significantly lower than vertical resolution of logs provided by HRAI tool. Therefore, thin-bed problem is especially visible in boreholes, where DIT was primary tool used for determining formation resistivity.

To overcome these limits globally optimized iterative inversion algorithm was applied to deep and medium resistivity logs recorded by DIT. The algorithm was tested on resistivity logs recorded in borehole, where DIT and HRAI tool were run in the same depth interval. Resistivity models obtained for DIT deep and medium induction measurement provide level of details close to HRAI logs with a similar depth of investigation. Therefore, proposed algorithm is a promising method for improving quality of gas saturation evaluation in boreholes, where DIT was primary tool used for determining formation resistivity.

EXPRESS

Nowadays fast delivery of medical help to victims is a very popular slogan. Modern technologies such as unmanned aerial vehicles are the future solution to this problem. The High Flyers [1] team took on the challenge of UAV Medical Express 2018 [2] in Australia to build a fully autonomous unmanned aircraft for blood transport, capable of one hour flight and a vertical takeoff and landing. It will have a unique feature among similar solutions - a vectorized thrust of engines that ensures their usage in both vertical and horizontal flight. The author of the work undertook to design and create from scratch a dedicated servomechanism that accomplishes this process. While performing the research, the assumptions were taken into account - self-locking mechanism, the ability of the structure to transfer driving force, dedicated power source converting 25V voltage, dedicated electronic board and PID controller implementation. The design process of the structure included strength analysis, motion range research and prototype construction. The project of a dedicated PCB - made in SMT technology - includes calculations and simulations of the power source, correct placement of elements and their combination. The servo control software is driven by the main flight controller via the PWM signal, which is then transmitted to the engine driver via the PID controller. The project ended with the regulator's tuning process. The result of the work is a device combining three areas of technology - mechanics, electronics and automation. The servo will be used in the VTOL type aircraft being built.

Determination of band structure diagram of semiconductor heterostructures applied in photovoltaics

Rafał Bogaczewicz 1,*, Ewa Popko1

Keywords: Semiconductor, heterojunction, band diagram, n-ZnO/p-Si, simulation

Over the past two decades the photovoltaic market has developed more rapidly than presumed by the most optimistic forecasts. Nowadays most commercial solar cells are based on silicon wafers; however, there is a race in search of cheaper solutions. Recently it has been shown that the heterostructures of n-ZnO/p-Si are a promising photovoltaic alternative to silicon homojunctions [1].

It is well known that the energy band diagram of a heterostructure is crucial for the understanding of the operation of a semiconductor device. This paper analyzes the n-ZnO/p-Si heterostructure band diagram. It is simulated by using free computer simulation tool for the analysis of device physics and device design, AMPS 1D (Analysis of Microelectronic and Photonic Structures) [1]. Obtained numerical results are compared with theoretical calculations based on the depletion region approximation model and the Poisson’s equation for electric potential. The results of simulations are also compared with the experimental dark and light I-V characteristics of the test n-ZnO/p-Si heterostructures made at the Institute of Physics PAS, Warsaw [1]. The fitting parameters used for the simulation were taken from the measured C-V characteristics and from the literature data [2].

It has been concluded that the presence of quantum wells and free carriers at the heterostructure’s interface constrain the application of depletion region approximation model: the theoretical results are in accordance with the numerical calculations only when quantum wells have little influence on free electron concentration. The numerical I-V characteristics based on simulated band diagrams are qualitatively consistent with the experimental I-V curves, confirming correctness of the determined band diagram of the n-ZnO/p-Si heterostructures.

1 AGH University of Science and Technology, Krakow, Poland

Roadways, as a linear source of pollution, pose huge danger for the environmental components located nearby. During the winter these emitors become more dangerous due to road salts application. The main point of this project is to determine the concentration of chloride ion accumulated in snow close to the roads around AGH UST campus in Cracow. Seven samples were obtained and one representative sample from the Main Square in Cracow. In order to determine chloride ion concentration, arganometric titration technique was performed, widely known as Mohr method. The analysis was conducted according to the international standard PN-ISO 9297. Concentration of chloride ion was compared to the decree of the Minister of Health and the Minister of the Environment. Both contains standards accordingly in surface water quality and water intended for human consumption. Obtained scores suggest that there is no evidence of excessive pollution around AGH UST campus, however high concentration of chloride ion equal to 486mg/(dm3)-1 was measured on Cracow’ Main Square. It might be a sign of human unaware behavior and uninhibitet de-icing salt application.

Development of digital material representation model of dual phase titanium alloy with lamellarmorphology of alfa phase

Mateusz Mojżeszko1,*,Mateusz Kwiecień1, Krzysztof Muszka1,Łukasz Madej1


Keywords: Titanium alloy, Digital Material Representation, Lamellar morphology

Development of the digital material representation (DMR)model of titanium alloyTi-6Al-4V for further numerical simulations is the main goal of the present research.The investigated titanium alloy has a two phase microstructure composed of beta matrix and alfa grains with characteristic lamellar shapes. Such morphology is obtained after specific heat treatment of the as cast ingots. Due to the complex shape of this composite type microstructure, numerical modelling of further deformation conditions requires explicit representation of both phases. That way their interactions and resulting local heterogeneities can be properly predicted.

To numerically recreate this type of microstructure morphology, the extended cellular automata grain growth model was used. Unconstrained grain growth algorithm based on the cellular automata (CA) approach [1] was developed and implemented using object oriented C++ language. Obtained representation of beta grains morphology is then additionally modified with the implemented algorithm from the computational geometry area introducing alpha phase elements in the form of parallel lamellas grouped and aligned with respect to the particular beta grain. The spacing between subsequent lamellas, their volume fraction, thickness and alignment in 3D space can be easily controlled.

Obtained digital microstructure morphology can be then discretized with the in-house finite element mesh generator DMRMesh[2], that can refine elements along the phase boundaries. Thus, developed DMR model can be used during subsequent finite element modelling of material behaviour under various deformation conditions.

Examples of capabilities of the developed algorithm in recreation of two phase titanium microstructure followed by a practical application case study will be also in presented in the work.

Development of meso-scale model of blood thrombosis

1 AGH University of Science and Technology, Faculty of Metals Engineering and Industrial Computer Science, Department of Applied Computer Science and Modelling, Kraków, Poland

Keywords: blood thrombosis, meso-scale model, finite element method (FEM)

Blood coagulation at the place of discontinuing the vessel is usually a beneficial reaction protecting the body from bleeding and maintaining hemostasis. Formation of a blood clot inside the vessel or mechanical device is a pathological phenomenon, highly dangerous, sometimes leading to serious complications. The aim of this study is to develop a meso-scale model of blood thrombosis using analytical equations to estimate the risk of coagulation [1]. The proposed meso-scale model is a part of multi-scale model of blood coagulation.

The meso-scale model of blood flow was developed using Navier-Stokes equations, and the blood thrombosis model was based on transport and diffusion equations. Identification of parameters of the meso-scale model was based on the micro-flow tests. The meso-scale model of blood thrombosis was developed using methodology described in [1].

The Casson blood rheology model was selected in the present paper for solving blood flow modeling tasks [2]. The models of micro-flow tests for channels of various shapes were developed using a finite element method in the Ansys CFX code. Equations describing levels of concentration of factors responsible for blood coagulation (such as thrombin and others) were introduced into the Ansys solver. Thus, simulation of blood flow was done and risk of the clot formation was estimated basing on the micro-flow conditions.

The real micro-systems suggested for validation and development of the meso-model of blood thrombosis were prepared by the Wroclaw University of Science and Technology. The proposed device is a microfluidic chip with characteristic dimensions starting from a few microns (depth) to tens-hundreds of microns (width), whose shapes were based on the literature [3].

The results of blood micro-flow simulations and the meso-scale model of blood thrombosis will be the first phase of development the multi-scale model of blood thrombosis. Calculated velocities and force fields in the meso-scale, as well as concentration of thrombotic factors will be transferred to the micro-scale model of blood thrombosis as the boundary conditions.

Development of the Finite Element Method heating model for forging process of fasteners

Karolina Czechowicz1,*


Keywords: Finite Elements Method, heat treatment, applied computer science, metals

engineering

This project’s goal is to solve technological problem occurring in a fasteners production plant. Tools for the production of fasteners do not achieve required properties after heat treatment processes which causes faster tool wear. The reason is insufficient heating time before hardening. Therefore the main task of this work is to develop Finite Element Method (FEM) software for prediction of optimal heating time.

Distribution of heat over time is described by a differential Fourier equation. Solution of this equation is achieved in the application with a use of mentioned Finite Element Method. The analyzed tools are axially symmetrical, so it was possible to represent them with two-dimensional geometric models. Since their shapes are not very complicated, the algorithm for simplified mesh generation was implemented. Each of the shapes was divided into rectangles and meshed individually using triangular finite elements. Because the problem is highly specified, it was possible to create intuitive Graphical User Interface (GUI), easy to operate for unexperienced user. GUI was implemented using Windows Forms interface. The developed software was verified using commercial package Abaqus FEA. The obtained results are presented in this work as well.

DFT approaches for resiliency estimation

Michał Mursztyn1,*

1 Bialystok University of Technology , Faculty of Computer Science, Bialystok, Poland

Keywords: resiliency, DFT, GPW, liquidity, stock market

Resiliency is one of the dimensions of liquidity that tries to capture recovery speed to its fundamental level of either market or a particular asset [1][2]. It has been said that liquidity dynamism can be described in terms of resiliency[3]. The dimension itself has hardly been investigated in the literature and little empirical research has been conducted. It is related to difficulties with defining a straightforward indicator to gauge specifics of the phenomenon[4].

There will be introduced theoretical examination of resiliency as well as some existed empirical results for the Warsaw Stock Exchange (WSE). Specifically, a solid foundation of resiliency as one of the dimensions of liquidity and its estimation methods discussed in the available literature will be presented, emphasizing usage of Discrete Fourier Transform with some related problems like window function impact on the proxy.

The core goal is comparison a conventional DFT resiliency estimator with a new one that is based on intraday resiliency values for each trading hour. It is important to note that this new proxy unveils intraday patterns of resiliency and makes it comparable for each asset separately and amongst them.

Thus an additional aim is retrieving those intraday resiliency patterns and presenting their relationship with broadly perceived liquidity. The calculations has been made utilizing high-frequency data.

Diffusion-type cloud chamber cooled by liquid nitrogen

Paweł Jagoda1,*, Paweł Janowski1

1 AGH University, Faculty of Physics and Applied Computer Science, Krakow, Poland

Keywords: diffusion cloud chamber, cosmic radiation, charged particles, liquid nitrogen

Particles from outer space (cosmic radiation) arrive continuously to Earth (some just pass

through unnoticed) - they are non-visible and sometimes mistaken for environmental

radioactivity. Air showers induced in Earth’s atmosphere are caused by interactions between

air molecules and cosmic rays which produce cascades of lighter particles. The most

energetic primary cosmic rays produce cosmic-ray ensembles of great magnitude. Charged

particles passing through cloud chambers leave tracks which can be registered by camera.

Not so long ago these type of detectors were widely used in investigation of radiation.

In simple terms cloud chamber consists of a tank, alcohol vapor source and refrigerated plate. In my project a piece of felt soaked in alcohol is attached to the top of the closed tank. The bottom of the tank, which is a plate made of Al, is cooled by partial immersion in liquid nitrogen. Alcohol vapor is descending in steep temperature gradient from warm top plate to cold bottom plate, which results in supersaturated environment just above it. As such chambers acquire stable conditions it starts working. Charged particles either from environmental radiation or from secondary cosmic rays leave ionization trails around which vapor condenses resulting in visible tracks.

Our project is focused on construction of airtight container for alcohol vapor environment, such structure has to withstand over 100 degrees Kelvin difference between elements. What distincts this cloud chamber from others is its coolant, liquid nitrogen was used because of its low cost and availability at faculty. Major part of the project was to develop heat exchange system, used radiator is fitted with copper and aluminium tubes of various lengths to ensure stable and not to low temperature at the bottom of tank. Gained experience will surely help me with future projects.

Keywords: electric scooter, scooter, mobility, vehicle, transport

Our motivation to build an electric scooter was the desire to build a modern electric vehicle, that would be as practical as possible in everyday use and give the owner new opportunities in quick travelling through the city. We want to promote electric drive as an ecological source of power for vehicles, especially in small, mobile vehicles.

The main objectives, that our vehicle must meet are: reaching a speed of 25 km/h, range on a single charge of 20km, weight below 10kg and foldable construction, creating a compact body for easy carriage in public transport.

We have currently built a drive system with engine and battery. The next stage is the construction of aluminium profiles, entirely made by us. The main challenge is to build an element connecting the platform with the steering wheel, which allows it to fold in two joints at the same time having the least possible clearance, so that riding on a scooter will be safe and secure.

We will present the basic configuration of our vehicle and we will talk about plans for its expansion and equipment with new elements. We hope, that thanks to our project, knowledge about electric vehicles in our environment will be greater and electric drive technologies will gain more and more supporters.

Keywords: electric, vehicle, innovation, motorcycle

The market aims to reduce carbon dioxide emissions to the atmosphere. Modern transport often means giving up internal combustion engines to electric drives that are environmentally friendly. The E-Moto AGH team together with the project "E-Moto AGH - off-road electric motorcycle" was constructed in order to show the public the possibility of using an alternative energy source. The off-road electric motorcycle of the E-Moto AGH team, constructed for the 2017/2018 season, is the second vehicle of this type that was made at the AGH University of Science and Technology. The use of an alternative energy source to power the drive gives an advantage over vehicles with an internal combustion engine, eliminating not only the pollution problem, but also the noise accompanying the engine operation. The most important parameters of the motorcycle:

• BLDC motor placed in the frame, • Li-Ion batteries, • range: up to 100km (in terrain) • frame made of S355J2 steel of the original design, • swingarm made of 6083-T6 aluminum alloy of the original design, • carbon fiber housing, • on-board computer, • dedicated smartphone application, • maximum speed: 120 km/h.

The motorcycle enabled the start in the SmartMoto Challenge Barcelona 2018 and SmartMoto Challenge Wroclaw 2018.

E-Moto AGH 2.0 – power supply for an off-road motorcycle

Gabriela Ważny1,*, Jacek Leszczyński1, Janina Molenda1

1 AGH University, Faculty of Energy and Fuels, Department of Hydrogen Energy, Krakow, Poland

Recently, the subject of electromobility is becoming more and more popular, mainly due to the growing public awareness of environmental pollution resulting in the international decisions and declarations of individual countries. This currently developing market meets with great interest all over the world and plenty of events connected to this topic are organized. One of them is Barcelona Smartmoto Challenge (BSMC), which is a competition for student teams building their own electric motorcycles. 2018 edition was focused on an off-road motorcycle and was the main goal for E-Moto 2.0 project. E-Moto AGH Team is created by AGH University of Science and Technology students, divided into 8 sections from 3 Student Scientific Circles (SSC). The group of students from Hydrogenium SSC has focused on the design of a motorcycle battery.

The power supply for the motorcycle is mainly the construction of the battery with the appropriate parameters. For this purpose, the cell type has been chosen. Such application as off-road motorcycle requires precisely selected models, able to provide high capacity and durability under high current. Few commercially available cells have been examined in laboratories, which allowed to choose the most suitable ones: SONY US18650VTC6 and LG 18650 HG2. As one of the BSMC requirements was the battery to be quick removable, it was decided to prepare two battery packs. 432 cells (24 in series and 18 in parallel) per each pack have been spot welded with a nickel tape. In addition, cell holders have been designed and manufactured to combine them into packs. Copper bus collects current from parallel connections at the ending at the top of the pack. The replaceable casing with a suitable shape that fits into the frame of the motorcycle was also designed and manufactured. In E-Moto AGH construction it has been decided to put into the battery casing not only Li-ion cells and BMS, but also some auxiliary devices like contactors, relays, pre-charge circuit and fuse; therefore each battery pack has its own electrical circuit.

All these features make the battery safe, comprehensive and exhibiting parameters suitable for heavy-duty operations. Easy removable battery has been especially appreciated in Wrocław SmartMoto Challenge 2018, where E-Moto AGH Team won "The Best Battery Package Solution" award.

Keywords: Anaerobic digestate, Antifungal activity, MIC, Phytopathogens

Pakistan is an agricultural country. The increased population leads to increasing demand for food. Unfortunately, crops are infected by different microbes and nutrient deficiency of soil adversely affects the yield of the crop. Furthermore, the use of chemical fertilizers like Nitrogen, Phosphorus, Potassium (NPK) Urea, and Diammonium phosphate (DAP) and pesticides have environmental consequences so there is need to find an alternative renewable and sustainable biofertilizers. Maize is capable of phytoextraction from contaminated soil and one of the top growing crops in Pakistan, unfortunately, it has low yield compared to other countries due to deficiency of organic matter, widespread nutrient deficiencies (deficiency of phosphorus and nitrogen), unbalanced use of fertilizers, disease, and pest. Digestate as partially degraded organic material residue has been suggested for the control of a few plant diseases is the better replacement for the chemical fertilizers.The present study was designed to evaluate the antifungal activity of anaerobic digestate and its effect on growth and yield of maize. The antifungal activity, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC) against selected phytopathogens (Colletotrichum coccodis, Pythium ultimum, Phytophthora capsci, Rhizoctonia solani, Bipolaris oryzae and Fusarium Fujikuroi) was determined by microtiter plate method. The effect of various fertilizers in different growth parameters height, diameter, chlorophyll, leaf area, biomass, and yield were studied in field experiments. The extracts from anaerobic digestate have shown antifungal activity against selected phytopathogens, the highest activity was noted against P. ultimum, the MIC activity was high in case of P. ultimum and B. oryzae. The present study concludes that anaerobic digestate have a positive effect on maize growth and yield as well as an antifungal activity which can be potentially a good biofertilizer.

Evaluation of the efficiency of removal of heavy structural components from oil by the method of cold rod

Ademuwagun Temiloluwa1,*

1 AGH University of Science and Technology, Faculty of Energy and Fuels, Department of Chemical Technology, Krakow, Poland

Keywords: cold rod, asphaltene, paraffins, heavy oil deposit, viscosity, emulsion

In present times, the extraction, preparation, transportation and processing of heavy oils are difficult because of their high viscosity, density, pour point and the abnormal rheological behavior. These problems are due to the presence of heavy components in oil – asphaltenes, tar, high-molecular paraffins and ceresins. During exploration, their negative influence can be prevented by the introduction of different reagents into the flow – additives for lowering viscosity, depressants and inhibitors of paraffin deposits[1].

The essence of this proposed work is to develop and design compact technology for the removal of high-molecular components from oil such that some of its exploitation properties would be upgraded. A physical method of oil treatment was used during research[2]. The oil is put into a cooling apparatus with four spaces after which the cold rod is placed into the spaces. The temperature in the apparatus is being regulated and fixed at specified values.

The result of the application of this technological consists in the processing of oil flow with cooled rods/plates, which is expected to decrease the oil’s viscosity, density, and remove a part of the water phase, if the processing is subjected to a water-oil emulsion system. A schematic diagram was developed which allows the implement of technology in form of a separate industrial unit working in a continuous mode.

FinTechs, Blockchain and other New Technological Phenomena in the International Capital Markets

Łukasz Chyla1,*

Keywords: FinTechs, Blockchain, Capital Markets, Algorithm Trading, Artificial

Intelligence

International Capital Markets have started to feel the presence of some new technological phenomena. Numerous research studies show, that on the world's largest stock exchanges, orders generated by automated systems (so- called algorithm trading or high-frequency trading) already account for over 50 percent of daily turnover. American stock exchanges have already experienced even the first mini-crashes caused by mere errors resulting from the algorithm software, causing chain reaction. Similar technological phenomena that change the face of stock exchanges and regulated markets include, for example, Dark Pools, Phantom Orders, Naked Short Selling, Cross-Selling and Artificial Intelligence. Moreover, visible is the rise of the so-called Fin-Techs, Cryptocurrencies, Blockchain technology and Tokens, which constitute a new, alternative method of raising capital from investors by the innovative companies, allowing to avoid very costly, rigorous prospectus regime and transparency obligations that other publicly-listed companies are usually required to meet. In particular, Blockchain technology is the one connected with significant potential and opportunities, but also various risks – especially from the perspective of protection of numerous retail investors upon which the strength of the capital markets rests. For the first time in history, the pace of technological development overtook the law so significantly, that it caused general information and regulatory chaos threatening the general cohesion of the Capital Markets. Even in the EU itself, some countries implemented regulatory barriers to the development of these technologies, while others welcome them with open arms. The importance of the above considerations stems from the fact that international capital markets are the flywheel of the whole economy, allowing publicly-listed companies to acquire cheap and effective investor capital for further development, as opposed to expensive and risky capital from creditors. The aim of the conference paper is to present individual opportunities and threats that new technological phenomena bring in the capital markets, as well as to try to capture the direction of legal changes to tackle them, in which European and world legislators are heading.

Keywords: 3D modeling,floodlight, light distribution, ies format

Presented materials discuss simulating light distribution using geometric model and open source 3D graphics package – Blender 3D. Research was based on floodlighting of Lubomirski Palace located in Rzeszów – an interesting object due to a lot of details and ornaments on the elevation. 3D model comprising all those distinctive features was created first, including all the reflective and absorptive materials and textures found on the outside walls of the palace. Research concluded on site allowed for precise location of floodlights in the model, based on existing handles prepared for lighting installation around the palace. Using blueprints for the real lighting installation and floodlights models in IES standard realistic lighting conditions were created. From many possible placement and intensity configurations most aesthetically pleasing was chosen for in-depth explanation and analysis. Different lighting phenomena was also modeled and analyzed during research, such as mirror reflections, Lambert reflections, inverse-square law and methods of digital recording of photometric solids. Presented work describes in detail such elements of the simulation as 3D mesh structure, texture parameters and numeric calculations of luminance distributions on lighted surfaces. Additional research result is a suggestion of lighting for the palace which aims to emphasize architectural values of the object at night time. Whether this suggestion will match features of real installation planned for the palace remains to be seen after its assembly.

1 Lublin University of Technology, Faculty of Biomedical Engineering, Lublin, Poland

Keywords: 3D modeling, computed tomography

3D modeling is not easy, but can be very helpful in medicine. Thanks to the new technologies such as computer aided engineering (CAD), modern tomographs and many computer programs i.e. Mimics. Engineers can 3D print organ models, make calculations about body part's toughness, damages, or just pressure dispersion.

To design full-size skull model we used Mimics 13.1 program developed by Materialise company. This is an environment dedicated to transforming medical images and generating 3D models. In process of transforming, using tools such as choosing HU range, Calculating 3D we achieved Point Cloud representing skull's bones. This type file can be exported to another computer programs in order to: - skull reconstruction in Catia V5, - calculating i.e. pressure generated during traffic accident, or stress caused by drill during

trepanning. For this action we use program called Abaqus. This paper shows techniques of bones reconstruction based on images taken by

tomograph. To illustrate model designing we used skull 2D pictures made by tomograph and saved in DICOM format.

Using computer aided engineering helps to create virtual bone model which can be used in planning surgical operations in example filling skulls deficiency or pre-fitting (personalize) parts which will be implanted into patient.

Generation of digital material representation model in three dimensional space based on cellular automata sphere growth algorithm

Lucyna Hajder1,*, Lukasz Madej1


Keywords: digital material representation, sphere growth algorithm, cellular automata

Development of efficient numerical algorithm for generation of three dimensional synthetic microstructures for further numerical modelling is the main goal of the present research.

The circle/sphere/ellipsoid growth algorithm implemented within the cellular automata framework is often used to create synthetic digital representation of investigated microstructures see e.g.[1-3]. However, the approach is usually used in 2D computational space due to the simplicity in implementation. However, when a complete information on microstructural state is required, such 2D representations are not sufficient.

Thus, the three dimensional version of the cellular automata (CA) sphere growth algorithm is implemented with the work. The general concept of the approach is to fill the computational domain with spheres, which size distribution is consistent with the specific required distribution described by e.g. uni- or bimodal curves. In the present work the synthetic microstructure is generated in four major steps: generation of 3D cellular automata computational domain, generation of spheres with required size distribution, closed packed filling of the computational domain with generated spheres, evolution of the spheres according to the unconstrained CA growth algorithm.

Three different algorithms of space filling have been implemented to provide required flexibility: Gaussian distribution, gradient filling and specific size filling. To reduce computational complexity, the rotation of the spheres is based on the vector accounting for the distance from the obstacles (computational domain boundaries and other spheres). Finally, the CA grain growth algorithm has implemented using threads mechanism allowing parallel execution of computations.

Detailed description of developed algorithms as well as examples of obtained various three dimensional digital material representation morphologies are presented within the work.

Glioblastoma: an updated study on the state of knowledge of its molecular biology and treatment

Belén Delgado-Martín1,*

1 Universidad de Málaga, Andalucía Tech, Facultad de Ciencias, 29071 Malaga, Spain

Keywords: glioblastoma, classification, genetic aberrations, pathogenesis, therapies

Gliomas are the most common primary brain tumours in adults. They arise in the glial tissue and primarily occur in the brain. The World Health Organization (WHO) classifies gliomas in WHO grades I-IV based on their malignant behaviour. WHO grade IV glioblastoma is the most common and deadly glioma, with an incidence rate from 0.59 to 3.69 per 100000 people [1]. Low-grade tumours of WHO grade II tend to progress to high-grade gliomas of WHO grade III and, eventually, glioblastoma of WHO grade IV, with a median survival of 12 to 15 months after the final diagnosis [2]. In the past 50 years, primary treatment has involved surgery followed by radiotherapy. In 2005, chemotherapy agent temozolomide was added to conventional treatment and radiotherapy plus temozolomide has now been adopted as the standard of care [3]. But, still, glioblastoma remains as an incurable disease. The search for new diagnostic approaches and more effective treatment strategies requires large-scale studies, integrating data from diverse molecular platforms in order to achieve a better understanding of the overall process and the identification of new therapeutic targets. Since glioblastoma keeps many secrets related to its development and pathological process, it is interesting to carry out a review about the available knowledge concerning this disease. This work, based on a systematic search of information in public and private databases (access provided by University of Malaga) provides an updated study on the state of knowledge about glioblastoma, focusing on classification, genetic aberrations, pathogenesis of the disease and the newest findings regarding therapies and targets.

Keywords: renewable energy, hybrid power system, energy management

The global energy consumption expected to increase by 37% to 2050 and has been expected a significant rise in the world electricity demand by 80% over the period 2012–2050 according to the International Energy Agency (IEA) report 2017 [1]. Despite the modern development in the electricity production by using modern technologies for production, grid extending, distribution supply and smart grid application system, still many challenges facing the grid extension network such environmental terrain, mountainous and desert sites where the network is exposed to many environmental and climate inelegances which require periodic maintenance and that turn lead to the cost of electricity supply. Recently, renewable hybrid power systems received most interest because of like these systems can overcome the intermittent nature of renewable sources, the over-sizing issue and enhance the reliability of supply [2]. The hybrid power system based on the renewable energy can be very helpful in many cases however proper system design required detailed information about renewable energy resources as well as about energy consumption including load daily profile and maximum power [3].

The paper presents an analysis of the photovoltaic base hybrid energy system. Input results used in the analysis are based on experimental measurement of solar radiation and electrical energy load and were carried out for the residential household at Krakow, Poland. The system consists of two types of energy sources combined with solar 2kW PV system and grid system. AC electrical load (energy consumption) and incident solar radiation were used for system analysis as well as in order to investigate the effect of temporal input data resolution (from one minute up to one hour) on the solution. The results clearly indicate that electrical high load temporal resolution is very important for the accurate evaluation of energy self-consumption while the solar radiation sampling acquisition is less sensitive for this parameter. For solar radiation accurate results (error below 10%) can be obtained with 15-60 min acquisition or averaging time while the required acquisition rate for the electrical load depends on the load profile and in many cases have to be as short as one minute.

The mission of the hybrid-propellant rocket Panda 3, which was built by a group of Polish students from AGH Space Systems, is to test all subsystems, achieve apogee at 3km altitude and to obtain successful vehicle’s recovery. This project started in October 2017. Since then, rocket motor, structure, recovery, other mechanical elements and all electronics systems have been constructed, prepared and tested.

The thrust generated by a hybrid rocket engine (with polyamide as fuel and liquid nitrous oxide as an oxidizer) provides the capability to conduct some scientific experiments in-flight, such as CanSats and other payloads, up to 4kg. Dual-event recovery ensures safe landing and possibility of multiple launches of the rocket. The structure of the rocket is based on laminates from carbon and glass fibre to minimise vehicle’s weight. Self-made electronic boards were designed to acquire data, provide long and low-range telemetry and control rocket’s behaviour during the flight. After many ground tests of all subsystems, in-flight test was carried out and the results were satisfying.

The project’s additional goal is to develop and popularize space technology in Poland. Furthermore, it is a unique possibility to develop skills and interests for students from AGH University of Science and Technology.

Information on the complex response of the irradiated brain could be the splendid source of knowledge about the impact of ionising radiation on tissue molecular profile. The research aimed to investigate the impact of sex and time on the molecular response to irradiation of murine hippocampal tissue. The mice were Co60 gamma irradiated, and then hippocampal tissues underwent the proteomic analysis in LC-MS/MS. Three endpoints were established – before irradiation, 24 hours after irradiation serving as the model for the acute response, and 18 months later, when the long-term effect was observed. The raw data presenting the protein expressions in the tissues were subjected to the conservative data filtration. There were 1184 proteins in the final set left. Two-way ANOVA was performed to identify proteins significantly changed with sex and time. Benjamini-Hochberg procedure was applied to correct for multiple testing. The massive response to irradiation was observed in time; 1144 proteins (96.6%) changed their expression level significantly (FDR < 5%). Huge effect size (Cohen’s d > 2) was seen for 1012 proteins with decreasing level of expression in time, and for only 24 proteins increasing in time. Comparison to the protein expression measured before irradiation revealed that all the response proteins returned to the initial level within 18 months of observation.

While differences in sex only were considered, 21 proteins depend significantly on sex and do not change in time. Twelve of them were of significantly higher level in males while remaining 9 were higher among female mice.

We conclude that the 0.5 Gy irradiation induces the massive response of the hippocampal tissue. The recovery time of 18 months allows the proteome to return to its initial level observed before the irradiation. There are no big differences in response between male and female mice.

.

The research included the influence of sous vide thermal treatment on microbiological quality of poultry meat and survival of Listeria monocytogenes bacteria. The meat was cooked in a water circulator at different times and temperatures, then its quality was checked using classical microbiology methods on culture and selection media. Meat microflora was identified by mass spectrometry. The sous vide technology is a method of thermal processing of raw materials packed in plastic bags, which are placed in a water bath.

Poultry meat (chicken fillet) was used in the study. The meat was washed and cleaned and then irradiated with UV light for 10 minutes on each side. Ten gram (± 0,5 g) samples were placed in PA/PE film bags and 100 μl of L. monocytogenes biomass was added, the samples were vacuum packed and incubated at 37 ̊C for 18 hours. Samples of meat were subjected to thermal treatment at 55 C̊, 60 ̊C, 65 C̊, at various times: 5 minutes, 15 minutes, 30 minutes, 60 minutes in a water circulator. After homogenization at 0.9% NaCl, Trypticasein Soy Lab-Agar TSA (Biocorp) and Listeria acc. Palcam Lab-Agar Base (Biocorp) were sown. Samples were tested on day 1 and 3. The number of colony forming units (cfu/g) was determined and identified by mass spectrometry using MALDI-TOF MS Biotyper (Bruker, Germany).

The number of colony-forming bacteria in heat-treated samples ranged from 2.41x10-5 (cfu/g) to 9.72x10-5 (cfu/g) on the first day and from 3.0x10-5 (cfu/g) to 4.95x10-6 (cfu/g) on the third day. The mass spectrometry test confirmed the presence of L. monocytogenes bacteria in samples subjected to thermal treatment 55 ̊C for 5 minutes, 15 minutes, 30 minutes and 60 ̊C for 5 minutes, 15 minutes.

The sous vide method is an effective method and can be used for microbiological protection of products, but special care should be taken when preparing meals, observing appropriate times and temperatures, and the product should be fresh.

Keywords: anti-dust masks, filtering efficiency, particulate matter, exposure reduction

Excessive air concentrations of the suspended dust in many cities around the world persuade the population to use personal protective equipment in the form of the anti-dust masks or other half face masks. The aim of the work was to compare the retainment effectiveness of the total suspended particulate matter (TSPM) and the PM2.5/PM10 fraction captured by the filtering materials used in selected types of the masks available on the Polish market, under the heavy usage conditions. The research was carried out in Krakow (Southern Poland) in the winter season, when the PM10 and PM2.5 air concentrations frequently exceed limit values. In the case of the TSPM, the filtrated air flow rate was maintained at about 3.7-4.3 or 8.5-8.8 m3/h during the simulations conducted in the similar laboratory conditions of well-ventilated indoor air. However, for the PM2.5 and PM10 fraction, the experiments were carried out under the outdoor air conditions for the fine and coarse particles in the ambient air using a reference low-volume sampler unit with the PM2.5 or PM10 inlet head sustaining the suction velocity of approx. 2.3 m3/h. The filtration efficiency was evaluated using the weighting method, including two stages of separation: the first stage based on the tested single- or multi-layer filter, and the second stage based on the final filter made of the glass microfiber. The obtained results allowed to draw conclusions regarding the assessment of the degree of reducing PM2.5 and PM10 exposure as a result of application various types of filters used in half face masks.

Keywords: surge arresters, metal-oxide varistors, impedance spectroscopy,

diagnostics.

Varistor surge arresters are commonly used for protection of electrical installations and electrical devices. During the exploitation, as a result of the occurring overvoltages, the structure of the surge arrester is gradually degraded. As a result, this process can change the protective properties of the varistor, leading to a reduction in the effectiveness of surge protection. Therefore, it is necessary to carry out diagnostic tests that determine the technical condition of the arresters.

The paper aims to approximate the working principles, structure of varistor and impact of aging with 8/20 μs current stroke on the dielectric properties of surge arresters. The aim of the carried out research was to compare and analyse changes in dielectric properties of low voltage surge arresters before and after exposure in the form of standardized energy pulses. Impedance spectroscopy was used to observe changes in the dielectric loss coefficient and the relative permittivity of the tested surge arresters. The measurements were carried out in a wide range of frequencies, from 10-2 Hz to 104 Hz.

The measurements showed an evident and degrading effect of current surges on the varistor's parameters. What is more, they also showed that the temperature changes of the tested surge arresters have a similar effect to the effect caused by aging with current surges. The choice of diagnostic methods is important for the proper diagnosis of the technical condition of surge arresters.

Keywords: hydrogen storage, metal-hydrides, hydrogen-powered boat

Nowadays one of the biggest challenge for humankind is to find zero-emission, reliable and efficient energy systems. Today, the fossil fuels are widely used, however they usage is a real threat to environment due to greenhouse gases emission (mainly CO2). From the above reason, we are looking for replacement of energetic systems based on carbon cycle. Renewable energy resources play a key role to do so; however, there is a significant problem with sustainability of energy supply. This is the reason why storing energy is the key to future zero-emission energy technologies.

Hydrogen as an energy carrier is considered to be one of the possible solutions due to clean energy recovery, with H2O as the only side product. Although technologies of hydrogen production and energy recovery are well established, the hydrogen storage is the main limiting factor for wide use of hydrogen.

Our project is focused on construction of hydrogen storage system based on composites consisting metal hydrides and thermal transport matrix. For this composite we used derivatives of LaNi5 and TiMn2 alloys as the active material, and aluminium/graphene as the heat transport matrix. Such type of container shows many advantages over commercially used methods, for example it offers high rates of absorption and desorption of hydrogen. This was achieved by nano-structurization of the active material by milling in high-energy planetary mill. The home-build hydrogen reservoirs exhibit excellent volume storage capacity of about 100g/NL and can be used for applications that do not require low-weight containers.

Final part of project was fitting home-build hydrogen storage to commercially available fuel cell in order to develop a complete propelling system, which can be mounted into some vehicle. The system was assembled inside custom-made boat hull with remote control system, which vividly presents possibilities and marks challenges of hydrogen used as an energy carrier. Thanks to the experience we gained, the propelling system is continuously evolving into more mature solution. *) Corresponding author: [email protected]

Keywords: 2D crystals, etching, AFM, oxide, heat

Due to recent interest and applications of MoS2 crystals in modern day electronic, it is important for us to understand how these MoS2 crystals behave under different heating conditions and how they can be oxidized. This contribution focuses on understanding how surfaces of thick MoS2 crystals behave under two macroscopic heating strategies: as a function of increasing heating time at 370 ͦC and as a function of increasing temperature from 345 ͦ C to 435 ͦC. AFM investigations during 1st heating strategy showed formation of triangular etch pits being mostly one monolayer deep. The average side of 8 selected triangles was 265 ± 49 nm and increased by ca. 100 nm for each 5 min of heating. Eventually, the triangles started to merge with other neighboring triangles until the top layer was completed etched off. In the case of 2nd heating strategy some triangles appeared, but were completely etched off, when the temperature increased. We observed a rapid reduction of the size of the MoS2 flakes after each heating step.

The results certainly show that apart from purely physical etching (1st set of experiments) there must be some other, chemical, etching mechanism (2nd set of experiments). In other to verify whether any new species, like Mo oxides, have appeared on the surface, Raman investigations were done on the heated MoS2 flakes. From the results we saw no formation of oxides. However it might well be that Raman was not sensitive enough to detect oxidation since the MoS2 flakes are very small (few microns in diameter) and eventual oxidation is limited to the top MoS2 layer only. *) Corresponding author: [email protected]

Mobile robot supporting American football training

Patryk Jakubiec1,*, Daniel Bachniak1


Keywords: American football, Safety, Sports technology, Robot

Scientific advancement has led to technology playing an increasing role in sports. Due to the use of technological solutions, it is possible to affect many on-field training factors, such as injuries, especially in a contact sport like American football. Hence, a large number of coaches decide to decrease the amount of contact during practices, by reduction or elimination of tackling at full speed. The most common solution is using practice equipment, such as tackle dummies or rings, which are made of soft foam. However, this leads players to have a tendency to forget that a real opponent moves and changes direction. These problems can be solved by using a mobile robot supporting American football training, which could be remotely controlled to behave like a real player. Such a solution allows to simulate real game situations which would be impossible by using classical training approaches. The construction of the robot consists of two parts. The upper one is in the shape of a high, truncated cone and represents a player of the opposing team. The bottom module is based on a steel frame which protects all the electronics. The bottom frame includes wheels, which enable the entire construction to move. Remote control is through a transmitter and receiver connected to the microcontroller. An important feature is the independent drive to the wheels by using two electric motors. Combining great maneuverability with powerful acceleration, results in ability to simulate real player behaviour.

In this work, the construction details and used electronic components are presented. The algorithms implementation are also described, especially remote communication aspects and motors speed control by using Arduino board [1]. Communication range, reliability and agility tests of the robot have been performed as well.

Keywords: electric vehicles, charging, load curve, modelling

The transition of energy system towards more sustainable one requires substitution of fossil fuels with renewable energy sources. Expansion of renewable-based power generation which is characterized by much lower GHG emissions is seen as a remedy for climate change problem. From the demand point of view large amount of fossil fuel, notably gasoline, diesel and LPG is used in in transport sector. The research question addressed in this paper is to which extend and how quickly fossil fuel vehicles can be replaced with electric ones in Poland. Ambitious plan for electro-mobility announced by the Polish Government in 2016 aims at 1 million electric vehicles in 2025. This number of electric vehicles is estimated to consume ca. 4 TWh of electricity per year i.e. 3% of the current final electric demand. However, if the charging process is left uncontrolled and if it takes place in the evening peaks instead of off-peak period during the night it may increase the risk of power blackout. Different distributions of time when costumer connects their cars to the grid have been considered to estimate the change of the load duration profile due to EV charging and assess this potential risk. The main analytical tool used in the study is the TIMES-PL model. This energy-economic model covers the transport sector as well as power generation and refineries and seeks for cost-optimal solution to satisfy the customers’ needs for energy services. The results show the dynamics of EV development, requirements in term of number of charging stations needed, the impact of transport sector transition on crude oil imports, energy security, emission of GHG gases and operation of refineries. *) Corresponding author: [email protected]

Circuits Theory

Memristors are non-linear two-way electronic elements that combine electric charge and flux linkage. The first person who described the phenomena occurring in memristors was Leon Chua [1].

Research on the subject of memristors is currently being advanced, with many research centers involved in the development of memristor technologies in order to expand the current knowledge about memristors. One of the main potential applications of memristors is the construction of computer memories.

Most people in the world dealing with memristor circuits build large structures which are tested only for logic gates. Memristors are just in two states: switched on or off. The purpose of this study is the analysis of the transient states, which will involve analyzing the systems from an electrical perspective.

In this paper, the author presents previous studies on memristors based on simulations carried out in the MATLAB environment. The author intends to carry out appropriate simulations on the actual memristor elements delivered from Knowm. The tested elements have a sandwich-like structure, in which the mechanism of electric-field-induced generation and the movement of metal ions through a multilayer chalcogenide material stack is used.

The paper contains an analysis and comparison of the results obtained from computer simulations as well as tests of real electrical systems.

The study analyzes systems composed of serial, parallel and also bridge connections of memristors. The analysis concerns both transient and steady states for different configurations of the memristors and different shapes of forcing voltages.

Multispectral satellite images as a source of information about illegal gold mines

Katarzyna Adamek1,*, Michał Lupa2, Wojciech Sarlej3

Keywords: Remote Sensing, Geology, Environmental Protection

Illegal gold mining is a long-term problem that occurs in many places of the world. However, in the recent years there has been an ongoing intensification of this process. It can be observed for example at Madre de Dios region in Peru [1]. As this region is the capital of country's biodiversity as well as one of the most valuable places in the world it has been chosen for the area of interest of this research. In the case of Madre de Dios, destroyed areas are part of the Amazon rainforest, famously called "lungs of the earth". Also fertile soils that could be used for cultivation are damaged. The pollution of the environment has reached a dangerous level to health in many places. Unfortunately there is lack of information about the scale of damages and pollution [2].

The aim of the project is to make a comprehensive assessment of environmental pollution, more importantly with usage of remote sensing methods. Due to many aspects including difficult field conditions, unstable political situation in an analysed area or dispersion of mining sites, it is reasonable to use remote sensing methods.

Obtained results allowed authors to observe vegetation loss and expansion of illegal operations. Analysis also opened up a possibility to track and interpret environmental chemistry. Acid Mine Drainage risk for this region was confirmed along with alarming level of deforestation. Also with usage of high-resolution satellite images more precise observation of mine site boundaries and tree cover loss were proceeded.

There are multiple benefits of developing a method for assessing environmental degradation using remote sensing methods. Most importantly, it could allow quick assessment, without the need for tedious field research. It is necessary to keep in mind that the problem may concern many countries and regions. The obtained results can be used as a help for the work of emergency services, humanitarian aid, or to conduct remediation processes.

Keywords: glucose sensors, copper sulphide, nanomaterials.

Diabetes is one of the most common diseases of affluence, especially in developing countries. All over the world, millions of people suffer from this illness. The key aspect of treatment is a precise and accurate measurement of glucose level in human blood. In regard to this circumstances, demand on more reproducible and reliable substitutes for commonly used enzymatic sensors become of great importance. One of the most promising technology is based on the application of nanocrystalline semiconducting materials. This new generation of glucometers is characterized by low detection limit, rapid response, selectivity, stability, and long-term activity. Among various inorganic compounds, copper sulfides attract a significant attention due to their availability, low-cost production and unique electrochemical and catalytical properties.

The aim of this work was to investigate the electrochemical behavior of flower like copper sulfide-based nonenzymatic glucose sensor. Physicochemical properties of obtained structures were investigated by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) and UV-ViS spectroscopy. Electrochemical measurements towards glucose detection were carried out using cyclic voltammetry method. Three-electrode system was proposed with a modified glassy carbon electrode by copper sulfides as working electrode, reference – silver chloride electrode (Ag/AgCl) and auxiliary – platinum wire (Pt). Selectivity was determined by addition of other electroactive species also present in human blood.

Keywords: marketing strategy, modern marketing instruments, one-page strategy

Strategic development and planning became an integral part of companies’ operating and they predetermine all the major fields of activities. Marketing activities are the key tools of communication with a company’s customers, suppliers and other stakeholders. Nowadays people are overloaded with information. That makes short but informative ways of presentation more attractive and popular. That is why companies are using more visuals with short text in their communication channels. It is not surprising that brief graphical representation is used in building strategies as well, and one of the most popular tools is one-page strategy plan (OPSP). As it comes from the name, it is a type of presentation of a company’s strategy that fits one page size, includes information about mission, vision, goals, as well as other vital information, normally in an image format. Among key advantages of this tool can be named (1) attractive way of presentation; (2) it contains only essential information; (3) it is easy to understand for any stakeholder. OPSP can be an effective tool for designing further marketing activities because it gives detailed and explanatory data about company’s background.

The research problem of the paper is how to develop the strategy in its short version, namely OPSP for the organization, which join the commercial and non-profit activities? Further, which is the role of the OPSP plan for designing marketing activities, specifically corporate movie scenario. That’s why the paper’s aim is to propose the model of OPSP plan for the AARONG company, which should include both, the commercial and non-profit activities. Additional objective of the paper is to propose the corporate movie scenario, which is based on the proposition of the OPSP. In the conclusion, it is captured the relation between those two elements. As a research method, it was used the case study of AARONG company, with use of the secondary data.

Keywords: lava flows, pyroclastic cones, eruption, Puca Mauras, Andahua Group, Peru

Thesis depicts the results of field studies of Puca Mauras volcano, made as part of the Polish Scientific Expedition to Peru 2017. The study area is located in the Valley of the Volcanoes in southern Peru. The selection of Puca Maura was due to the limited amount of information about this volcanic structure. The main objective was to determine if Puca Mauras volcano is a monogenetic structure by describing the petrographical features of lava. Samples were described with the use of a microscope and 5 of them were selected for ICP geochemical analysis. Examined rocks reveal moderate porosity and fluidal, porphyritic texture. Their mineral composition consists of plagioclase feldspars, amphiboles and pyroxenes. Morphological differences are bound to small variations of the chemical components of rocks. Rocks were classified as trachyandesites. The lava from Puca Mauras shows the highest diversity among the samples from all parts of the Valley of the Volcanoes. Studies lead to assumption of the existence of three main eruption stages. Products of the first stage of eruption, extremely rich in SiO2, represent a more evolved magma. Its advanced differentiation, took place closer to the surface. Proof of this is the iron-calcium garnet crystals found in them.

One of the most important practices in the production of some alcoholic beverages is ageing process. During that process, important changes occur, which results in improved sensory characteristics. Traditionally, several woods such as oak and chestnut have been used for manufacturing barrels. Oak is by far the most common wood for ageing alcoholic beverages [1]. However, physical and mechanical properties of wood barrel, like porosity that influence the gas exchange during ageing, can in some cases promote fast polyphenol oxidation. That effect could be minimised using cheaper non-oak wood alternative to barrel products like shavings or staves [2].

The phenolic fraction was considered to be one of the most important parameters for evaluating quality in the choice of good alternative aging wood [3]. So far, mulberry heartwood hasn’t been investigated too much in order to characterize polyphenols. However, according to some reports [3], polyphenols characteristic for mulberry wood were oxyresveratrol and its glycosides, as well as coumarin glycosides. Therefore, the aim of this research was to investigate phenolic profile of industrially dried mulberry staves originating from Serbia. Extract was prepared in 60% (v/v) ethanol, reproducing the condition of ageing process, and analysed by liquid chromatography coupled to diode-array detector and mass spectrometry. The results showed that mulberry was abundant in oxyresveratrol, taxifolin, (-)-catechin gallate, and phenolic acids, such as protocatechuic, p-hydroxybenzoic and ellagic acid. Also, fluorescence spectroscopy was used to characterize both wood sample and its extract. Characteristic emission spectrum of the wood sample showed the maximum at 420 nm, being blue shifted comparing with the maxima of most hard- and soft- wood species. This may be addressed to a relatively low content of lignin in mulberry wood. The extract showed a maximum characteristic for the major polyphenols of oxyresveratrol and coumarin type.

Problems of aircraft air supply systems, EC and LS systems

Sara Sibiga1,*, Marta Szczurek1

1 AGH University of Science and Technology, Kraków, Poland

The environmental control system (ECS) of an aircraft provides air supply, thermal control and cabin pressurization for the crew and passengers. But as a passengers all of us fell inconvenience while flying compared to natural air conditions. The atmosphere at typical jetliner cruising altitudes is generally very dry and cold. A certain minimum supply pressure is needed to drive the air through the system, but it is desired to use as low a supply pressure as possible, because the energy the engine uses to compress the bleed air is not available for propulsion, and fuel consumption suffers. In our paper we would like to show main problems with ECS mostly focused on pressurization. Also present our research of aeroplane model in made by us horizontal aerodynamic tunnel.

Keywords: temperature, measurement, station, array, HVAC

HVAC systems account for more than 50% of the energy costs consumed in European office buildings. The traditional control of these systems is not always adjusted to the load of buildings, which results in the lack of adequate comfort levels and irrational consumption of electricity and heat.

During the work on the oBEMS(Office Building Energy Management System) research project, a there was a need to measure the air temperature in rooms with a dense measuring grid. In response to this need, a prototype of a mobile temperature measurement system was created.

The purpose of this article is to present a process of designing and manufacturing a portable temperature measurement system.

Keywords: Phase Change Material, Energy storage, Phase transition

Project is about testing station for Phase–Change Materials. A Phase Change Material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. The testing station allows to determine the thermodynamic parameters of the phase transition. Measurement and recording of temperature and amount of heat input allow you to determine the enthalpy of the phase transition and the amount of stored energy. Peltier Modules are used to construct the station. These modules are the source of heat energy for the material being tested. Arduino is a microcontroller used to control temperature sensors and software. The obtained characteristics of PCMs are used to determine the temperature range in which the phase change occurs and the amount of stored energy.

Keywords: energy systems, energy storage, innovations

Renewable energy from the sun, wind, biomass or geothermal waters has become a very interesting topic, primarily for private households heating plants, power plants and hotels. These places are considered more environment-friendly than areas where conventional energy sources are used[1]. However, the installation of renewable energy sources is bound with a large investment because it is a large installation with high parameters [2]. This project draws society’s attention to the fact that even miniscule photovoltaic installations, which may be found in restaurants, hotels or parks, can contribute to the reduction of environmental pollution which people try to reduce every day.

In this research, the construction and operation of modern models of the solar energy storage are presented. The installations consist of the innovative models composed of photovoltaic panels, batteries and devices that receive the stored energy [3]. The project shows how much the energy costs can be reduced with a low investment, as well as the cost of maintaining the establishment. Especially in the summer months, when air conditioning is used, or during cold evenings, when the restaurant gardens are heated. Another goal of the project is to compare the costs incurred by the owner before and after installing the modern models and the rate of return of the invested money for the purchase of the innovative installations.

Keywords: emerging contaminants, oxidation, wastewater, treatment

The dynamically developing pharmaceutical market and increased consumption of medicines translate into an increase in the pollution of the aquatic environment with pharmaceuticals and products of their partial decomposition [1]. Many other compounds are also emitted into the aqueous environment from the wide use of personal care, cleaners and disinfectants [2]. These include triclosan, a bactericidal compound or bisphenol, a popular antioxidant. These compounds are released into the environment mainly along with municipal wastewater and as biologically active substances can be an ecotoxic threat to aquatic organisms and humans [3]. As much as 34% of the pharmacy drug market in Poland are over-the-counter medicines and they are detected in the environment most frequently and in the largest concentrations.

The aim of the project was evaluation of the removal efficiency of selected emerging contaminants such as pharmaceutical residues using ozonation and photocatalytic processes using titanium oxide, or sorbents with titanium oxide incorporated. The tests were additionally extended to the processes of preparing sorbents with titanium oxide based on selected minerals. The aim of the project was also to determine the effect of the catalyst dose and the time of the photocatalysis and ozonation process on the degree of degradation of pharmaceutical compounds. The analysis of the content of the tested compounds was carried out using liquid chromatography with UV-Vis detector. To determine the resulting metabolites, SPE solid phase extraction was used, and the analysis of the obtained extracts were carried out using a gas chromatograph coupled with mass spectrometry.

Keywords: Renewable energy sources, multi-family residential building, solar

installation, heat pump

Renewable energy sources in a multi-family building located in Białystok are take into considerations.

Three variants: variant I - solar installation, variant II - installation of a ground heat pump with vertical probes and variant III - installation with an air-source heat pump has been computed.

The analysed object is a multi-family building, built in traditional technology, free-standing, three-story, and basement. There are storage rooms and a boiler room in the basement. The building is located in the IV climate zone in Bialystok.

The economic analysis of investment showed which of the analysed variants is the most expensive investment - in this case a ground heat pump. The high cost is generated by the high price of the device and the expenditures necessary for drilling wells. The cheapest solution turned out to be a solar installation. However, this does not translate into savings achieved during the operation of this installation. The analysis showed that the exploitation of solar collectors is the most expensive solution, mainly due to the low energy yields of RES generated by means of collectors compared to the amount of energy that can be obtained using heat pumps. The most optimal solution seems to be the implementation of a variant with an air-source heat pump.

For the analysis a simple payback period has been used.

Jakub Liszcz1,*


Keywords: 3-5 keywords, separated by commas, typed in bold 8-point Arial.

Many small businesses in both production and service marks does not use fully information about its customers and results. The solution to this problem are for example computer programs for comprehensive financial analysis or for queuing, coordinating and making other processes related to the management of projects, for example contracted to perform work for client. The vast majority of them, however is not able to issue the need for the amount of cash on expensive licenses for such software, on the other hand they use Microsoft Office, not recognizing the untapped potential in it. Microsoft Excel spreadsheet allows to easily and quickly create a tool for the coordination of ongoing projects in conjunction with the analysis of impacts and costs associated with your business. Adding to this the opportunity to study the financial result in the selected time range or depending on the products or services sold, taking key decisions becomes much easier.

excitation, luminescence

In recent years, the field of renewable energy has developed dynamically in which the photovoltaic is becoming more and more popular. Unfortunately, the main barriers of the photovoltaic devices development is a high price and limited conversion efficiency. The down-shifting process is one of the propositions to solve the problem of low solar cell efficiency. The idea is to absorb the UV radiation, which is non-effective using by solar cells, and re-emit radiation in the visible range, which better match to solar cell respond [1, 2]. The properties of mixtures of ZnO powders with rare earth elements are used to achieve this effect. Rare earth elements are characterised a high yield of luminescence, whereas ZnO is a cheap, generally available and non-toxic material. In order to achieve the greatest possible benefits, it was decided to use mixtures of these compounds, which would result in low cost, high efficiency and broadening of the emission range in order to better match the tested solar cells [3].

In the research mixtures of ZnO nanoparticle (ZnO NPs) with average size of nanoparticle 20nm and rare earth elements (RE) are examined. Those compound are milling in 10 minutes using a ball mill in various mass ratio between ZnO NPs to RE (1:1, 3:1, 5:1 and 7:1). Subsequently, the photoluminescence properties of proposal mixtures are measured and analysed.

Scale model studies provide key solutions in the areas of science such as aerodynamics and fluid mechanics. Decreased dimensions of the objects under study and the knowledge on the relations between the model and its full-size equivalent allow conducting numerous tests at significantly reduced costs. In acoustics model studies are most commonly used for investigating the transmission of structure borne and airborne sounds, as well as for the studies on sound absorption phenomenon. Despite such a broad range of application, there is still no method which would allow scaling acoustic perforated panels without changing the values of their sound absorption coefficient. This paper presents the results of a comprehensive analysis on scaling the perforated panels; a number of theoretical and numerical analyses on the measurement samples at 1:1, 1:3 and 1:8 scales will be presented, together with the results of air flow resistivity measurements. The main parameters taken into consideration were the geometry of the samples and their flow resistivity, which is one of the most important parameters which determine the acoustic properties of the materials. These analyses were aimed at finding the basic relations which will allow scaling this type of acoustic panels. These relations will in turn allow producing scaled measurement samples serving as equivalents to full-size acoustic panels, which as a consequence will facilitate the process of designing acoustic perforated panels, keeping the costs of producing the prototypes low.

Keywords: seasonal coefficient of performance, air to water heat pump, ground to

water heat pump, groundwater to water heat pump.

Being observed global warming made European Economic Area advance heat pump as heat generator in member states. According to EU commission decision [1] air-air heat pump (ASHP) should provide SCOPne=2.5 at least, in the cases of ground-water (GSHP) and water-water (WSHP) heat pumps SCOPne=3.5 or more. SCOP is calculated using EU standard. However, the standard does not assume additional equipment which is required in some circumstances. Hence, the modified algorithm, which include buffer tank in the case of greater power compressor or separating heat exchange in the case of water-water heat pump, is applied. Heat pump units with three different heat sources are investigated theoretically. The comparison is made in the five climatic zones in Poland. To estimate external temperature conditions heating degree days are used. Ground temperature profile is estimated using semi empirical Baggs formulas [2], [3] with modifications to Polish conditions done by Oleśkowicz et al. [4]. The temperature profile is averaged in each climatic zone. Groundwater temperature is estimated using Kowalski formula [5]. Sense of each kind of heat pump application is investigated using average electrical energy production efficiency and low voltage electricity transfer efficiency in Poland.

Underpinning is the process of support to an existing foundation to provide either additional depth or an increase in bearing capacity. Underpinning may be necessary when: the foundation is cracked or weak, the properties of the soil may have changed, the construction of nearby structures requires the excavation of soil supporting existing foundations, the usage of the buildings has changed or it is more economical to work on the current building than to build a new one. The choice of an optimal solution of technological and material undertakings can be facilitated by using multicriteria decision support methods. The article presents DEMATEL method as a possibility of presentation an optimal solution on the example of technological and material undertakings of the selected methods of underpinning foundations. The research consisted in choosing technological and material methods of the selected methods of underpinning foundations, then creating matrix and selecting features and technological and material undertakings. The results were presented in DEMATEL method chart. The calculations were prepared using Mathcad programme.

Many parameters are used for rating the quality of the sound field inside the qualified acoustic halls describing the strength, clarity, definition of the sound and speech intelligibility. Sound field diffuseness and spatial impression parameters are used very rarely because of the problem in their measurements and interpretation. Previous research in that topic provided many sound field diffuseness coefficients, usually complicated in estimation and measurement. There is lack of conclusion and complete thesis on this subject with the interpretation of the results. This paper present the method for the sound field diffuseness level estimation basing on the example measurements of the Łódzka Philharmonic. New directional parameters were proposed, based on the statistical analysis of the reflections incidence angle and their amplitude. The paper contains discussion on the acoustic fault detection with the proposed method, including possibilities of marking them with the sound field diffuseness problems and ununiform spatial distribution of sound reflections. Summary was made, rating the usability of the selected parameters and their importance for the spatial impression. Performed experiments allowed to set the direction of future work in the taken field of the study, especially the application of the proposed method for extended sound field diffuseness ratings with methods based on different physical principles, including directional, energetic and time coefficients.

Keywords: trolley, stair, transport, electric drive, stair climber trolley

Moving heavy objects to higher floors is hard work, especially in the absence of lifting devices (elevator, conveyor, etc.). Most of the buildings are structurally crowded and are not equipped with elevators or escalators. As a result, new solutions are being sought to minimize the inconvenience of manually transporting heavy loads between different levels. The paper presents a project for improving hand-held stair-way trolleys by installing electric drive, which will result in even better improvement in the transport of items between floors and significantly relieve people whose professional work is associated with such transport. The study showed the need to develop and modernize mobile stair trolleys. In order to design the trolley, numerous multi-criteria analyzes were carried out, thanks to which an appropriate type of a stairlift was selected, the type of drive as well as materials for its implementation. The trolley construction, assembly drawings and executive drawings were created in the SOLIDWORKS graphics program. The machining of selected elements was carried out using the Mastercam X5 program. The final result of the work is a ready-made project of an automated stairlift. The next step of the authors may already be to create a prototype.

Keywords: apartment building, steel structure, high-rise building.

Within the 7th semester studying program the students of urban design group were offered to take part in the annual student competition “Steel Freedom Architecture Festival”. A plot with area of 5 hectares located in Kyiv on the intersection of inner beltway and the main street was chosen for design. The malls “Plasma” and “Macros” with many functions of trade, public service and entertainment are located in the immediate surroundings of the area.

The team of authors proposed a project of three residential buildings with a height of 34 floors and triangular in shape, each of which consists of three parts, united by a common node of vertical communications (elevators and stairs). The outer shape of each floor’s plan is a broken line, due to the design scheme of the house and the functional zoning of apartments. On each floor there are apartments of different types: one-room (100 m2), two-room (137-154 m2) and three-room (162-189 m2).

To provide a favorable living environment and contact with nature, on the terraces of 34, 32 and 30 floors were designed gardens. On the roofs of parking at the 12.5 m level it is also designed decorative greenery with area of 2900 m2 on each of the roofs, intended for the rest of the inhabitants.

The construction of all projected objects (residential 34-storeyed houses and 4-level parkings) is made of steel elements forming spatial frames. The construction of high-rise residential buildings is based on the diagrid system which allows the effective use of steel in creating bearing elements and simultaneously developing the spatial structure of the facade. Façade constructions are based on double-skin system, and consist of two contours. The outer contour forms the entire surface of the façade and the inner contour consists of sandwich panels and insulated glazing. Made in nomination “Housing Estate” of “Steel Freedom Architecture Festival” the project was highly appreciated by competition jury and was awarded a second prize.

Stents in electromagnetic field

Adam Dorsz1, Marek Petters1,*

1 AGH University of Science and Technology, Faculty of Electrical Engineering Automatics Computer Science and Biomedical Engineering, Department of Electrical and Power Engineering, Krakow, Poland

Keywords: stents, electromagnetic field, electromagnetic induction

The effect of the electromagnetic field (EMF) on living organisms has been researched for thousands of years. This issue applies to many aspects, as well as confirmed or denied effects [1]. Norms and recommendations of international organisations and national regulations prevent possible exposure to this effect [2]. Many dissertations present the effect of the EMF on implants inside the human body, for example, cardio-implants, aka pacemakers [3]. One of such implants that should be considered is a stent. The article presents results of investigations on interaction between stents and magnetic component (MF – magnetic field) of electromagnetic field (EMF). Stents are usually manufactured with specific materials, such as nickel-titanium alloy [4]. Stents structure is defined by tens of closed contours, penetrated by the magnetic flux [5][6]. Given the magnetic component changes in time, the passing of a magnetic flux induces the electric field in the branches of a stent, which then leads to the flow of an electric current [7].

The authors present a numerical model that can be used to simulate the distribution of a magnetic field in a closest proximity of a stent, as well as it determines the values of branch currents. The results are compared with a custom-made physical model of the MF generator and a custom-made stent.

The results of this analysis may be used to evaluate risks of people's exposure to various devices generating EMF.

Keywords: ball cage, constant velocity joint, finite element analysis, fatigue

The constant velocity joint (CVJ) is mainly used in today’s automotive industry. Every car is using minimum 4 of them, for front and back wheels. More power engines vehicles, with driveshaft’s, and 4x4 cars also are including extra one inside the main shaft. As is shown, CVJ joint is one of the fundamental parts of today’s cars. Each one it is build of few elements, depends on the type of joint, in ball joint we recognize 6-8 balls, a hub with the inner race, axle stub with the outer race for gear and wheel side, ball cage, shaft and rubber boot. Critical parts of every joint are rubber boots and ball cage, as the weakest joint elements. Knowledge of stress and fatigue behaviour is important for constructing lighter constant velocity joints that are necessary for light electrical and hybrid cars. This paper refers to stress analysis of constant velocity ball cage and fatigue life of the element, under 4 types of simplified added movements: plunging in joint, plunging off the joint, bending up and down of the joint, every made for 3 types of ball cage. To solve the problem, the Ansys Workbench software was used. Moreover, for the analysis, a special steel material model similar to AISI 8617 grade was prepared. The numerical results showed that type 1 and 2 have the weakest strength and fatigue ability, compared to type 3 of ball cage, what is similar to typical cage defects. The next step of investigation should include preparing special motion model with the best variant of the cage and evaluate the finite element model with real test results.

According to the Police statistics driving speed is indicated as the primary cause influencing road safety and leading to road accidents. Even though most of the accidents occur in urban areas majority of deaths is recorded in rural roads, especially on single carriageway. However detailed analyses generally focus on spot speeds and include national roads omitting the lower category roads even though previous research works show that speed on national, regional and district roads in many cases remains on a similar level. For this reason it is important to better recognize features influencing driver’s speed which directly affects safety on the roads with the emphasize given to the sectional speed which can better reflect natural drivers behaviour along longer section of a road and allows to eliminate temporal floating values of instantaneous speed. The paper presents research results of travellers speed on chosen regional and district roads located in Podlaskie Voivodeship, Poland. Test sections varied in terms of geometric characteristics. Speed measurements were performed with the use of a set of two ANPR (Automatic Number Plate Recognition) cameras. Conducted investigations allowed to compare driver’s average speeds and to evaluate the influence of chosen geometric parameters such as road accessibility, width of driving lane and shoulder or radii of horizontal arcs on average section speed.

Keywords: biopolyol, polyurethane, curing kinetics, DSC, thermogravimetry

Pro-ecological technologies of utilization of cellulose biomass attract a lot of attention. One approach to this issue is to use cellulose to fabricate various chemical components.

In this work, we present the preparation of biopolyols by liquefaction of cellulose by crude glycerol and then the application of obtained polyols to synthesis of polyurethane resins [1]. Various NCO/OH ratios and various compositions of biopolyol combined with a petrochemical polyol were used for polyurethane synthesis and the influence of chemical composition of intermediates on reaction kinetics was examined.

To investigate kinetics of the curing thermal analysis techniques – Differential Scanning Calorimetry (DSC) and Thermogravimetry were applied. Values for activation energies and pre-exponential factors in Arrhenius equation using various methods such as empirical model, isoconversional method [2] and multiple regression fitting [3] were estimated in dependence of chemical composition of the resins.

In conclusion, partial replacement of petrochemical polyol with biopolyols allowed us to obtain polyurethane resins and kinetic parameters of curing were calculated.

Keywords: PV temperature, solar energy, photovoltaic panel, PV efficiency

The photovoltaic panels provide the direct method to convert solar energy electrical energy. Large progress has been made in the development of PV panels with new concepts and significantly higher performance and at lower cost. The experimental measurement as well as CFD computer modelling play an important this technology development. It is know that PV cell temperature is one of the key for assessing the module efficiency. This temperature depends on many environmental parameters such as air temperature, wind speed, air pollution, solar radiation intensity and spectrum, climatic conditions and geometrical as the angle of incident irradiation, type of installation and, module configuration. It is known that the efficiency of PV modules decreases when its temperatures increase due to the solar radiation intensity, internal heat generation and the ambient temperature.

The aim of the research was to, perform an analysis of the PV modules using Fluent solver and experimental measurement. The fluid flow and heat transfer from a PV panel will be model by means of three-dimensional unsteady simulation with a radiation. The photovoltaic panel with the different mounting distance and the variable geometrical inclination was analysed under variable environmental and operating conditions. The results of the numerical analysis are compared with experimental measurements.

Keywords: process Z, rapid Z, linear energy, zinc galvanized steel

Currently, the process Z is used in galvanized steel welding. As it is known welding galvanized steel pose as big problem due to significantly increased spatter, released toxic fumes and defects owing to pores. Today weld joints of Zinc coated steel are done by spot-welding or braze welding both of which shows inferior mechanical properties of joints to what traditional welding offers. The primary target of this technology is Automotive industry which is in high demand for high quality welds on galvanized steel. This technology is based on synergy between Rapid Z current modulation, Autodrive Z wire feeder with ability to retract wire by 1 mm, Metalshield Z filler metal and robotized workstation to achieve weld joint with less than 1% porosity and guarantees weld clean of spatter. The paper presents a comparison of heat input calculated acc. to standards and measured using innovative method. Paper also include radiographic X-ray examination for all samples. Tests are carried out on the selected lap joints made of HX420LAD + 2100 steel with the use of robotic welding station. Implementation of process Z in Automotive industry would provide increase of quality and durability of welds inside our cars.

The architectural and spatial organization of the Hafen city Hamburg city and Vastra Hamnen in Malmӧ city

Halyna Petryshyn1, Yaryna Senkovska1, Nazar Pereguda1,*

1 Lviv Polytechnic National University, Lviv,

Keywords: postindustrial territories, landmark, housing function

Both Hafen City in Hamburg and Vastra Hamnen in Malmö are the postindustrial territories. Hafen City was a former port of Hamburg аnd Vastra Hamnen was the former shipyard area. They become abandoned industrial areas after the decay of the shipbuilding industry. It was proposed to restore these post-industrial areas and in both cases it was done at the initiative of state authorities.

The new concept of Hafen City territory development was to create a core with new central functions for the whole city and region, including landmark design, as well as replacement of old buildings with a new housing function, partial modification and addition of transport networks with further preservation of water artifacts. In Vastra Hamnen, they preserved the previous function (shipyard), but on a reduced scale. Today there are predominantly the combination of functions on both territories: public, residential and recreational. The wide network of bicycle paths have been designed, in particular along the coastline of Hafen City, with the aim of improving the environmental situation. In comparison, there was more attention paid to public transport, in Vastra Hamnen but at the same time the environmental measures were also been highlighted, in particular in production of electricity by wind turbines and solar panels. Today there is the dominance of buildings with indoor courtyards in Hafen City unlike Vastra Hamnen were the internal home territories are more open. In comparison, Hafen City is more open to the water. In Vastra Hamnen, the buildings are characterized by higher contrast, which reflected in the visual dominance of the skyscraper Turning Torso. It is the landmark of newly formed Öresundsregionen. One of the ideas was to create a new symbol of the city and change the city silhouette. Hafen City has a smoother transition of buildings’ height. It’s most important building is Elbphilharmonie. Nevertheless the main function of both regions is the residential one.

The borders of telematical experience

Kamil Kociołek1,*

1 Jagiellonian University, Institute of Philosophy, Krakow, Poland

Keywords: borders of perception, virtual reality, technological and social development

Telematical experience is an ability of experiencing in an electronical environment. This ability refers to a constantly growing field of experiences going beyond audio-visual transmission that is currently the most popular one. Devices enabling a transmission of smell and touch have been available for customers already. The development of such technologies is heading towards creation a world that is almost fully independent in its phenomena from our physical reality. Therefore there appears questions about the future and borders of the development of those technologies. This paper tries to answer to those questions. It shows whether we are able to find such borders and whether we are able to predict the future development of technologies that are using telematical experience. An analyse of correlation between human needs and abilities that are given by the technological achievements will show us whether the development of this technology is either beneficial and needed for the humanity. This will give the answer to the second question about the possible future of this technology and its possible borders. An analyse of possible borders and current technological achievements will allow us to answer to the first question as it shows whether we are able to find such borders in our technology, perception, intentional acts, or our political or ethical views. Because current technological achievements allows us to predict that the telematical experience can cross our personal limits as well as current limits of technology, the last anticipated border will turn out to be our ethical and political restrictions. Therefore only each of us, or we as a community, will have to answer to the question about the borders of telematical experience.

The concept of revitalization of the landscape around the Pototsky Palace in Lviv

Halyna Petryshyn1,*, Halyna Lukashchuk1, Vladyslav Kryvoruchko1, Adriana Kryvoruchko1

1 Lviv Polytechnic National University, Lviv, Ukraine

Keywords: revitalization, architecture, landscape, Ukraine, Lviv

Potocki's courtyard occupied a compact plot near Shyroka Street, near the city fortifications, on the left bank of the Poltva river. Fragments of the city's 19th-century plans show that in the depth of the yard there are 2 buildings - the front and side, and the broader kurderner has a traditional landscape style round parter. The creator of a garden was probably a city’s gardener Karl Bauer. On the map of 1892 a modern palace appears, which was built in the style of French classicism according to the adapted design of the Louis Dauvergne.

During its existence, the palace was reconstructed and changed its purpose according to the time conditions. In the 1980's, the Potocki Palace was one of the areas where construction work was carried out to pave the Lviv underground tram. As a result of these works there were changes in the soil and the palace got cracked, resulting in the construction of tunnels ceased and reconstruction of an object.

After the construction of the palace, green plantations continued to have an irregular landscape character until the 1980s, when a "French" parter was constructed, and the area on the front was covered with concrete slabs. Later there were created rows and flowerbeds with a different set of unrelated plants, and even more so with palace architecture.

The purpose of the project is to reconstruct the existing landscape around the palace, partial replacement of wood plants and adaptation of the site to the actual needs of the city. The initial idea was to recreate the landscape park that was in the early design of the site. Within the framework of the project, trees and shrubs that are self-contained and do not correspond to the style of the complex, are subject to logging. Also changed the boundaries of technical zones, the entrance to the palace, the system of tracks and proposed a system of pedestrian connections. Revitalized landscape is considered as a continuation of the artistic function of the palace.

Keywords: zinc alloys, silver, microstructure, mechanical properties, biodegradation

Among the group of materials used in medicine for short-term implants or stents there is a shortage of non-toxic materials that retain their mechanical properties long enough to support tissue regeneration. One of the possible materials is zinc [1]. Zinc is characterized by high biocompatibility, however it’s mechanical properties are insufficient [2]. With regard to the susceptibility of zinc to recrystallization and creep at room temperature, the goal is to hinder those processes and obtain a stable microstructure via alloying additions and various forming methods [3–5].

The aim of this work is to investigate the influence of silver additions on the microstructure of zinc, its mechanical properties and corrosion rate. Introducing additions of silver will increase solution strengthening and should also cause grain refinement of the microstructure. The produced alloys will be subjected to forming, namely indirect hot extrusion. The aim of this procedure is to efficiently refine the grains and strengthen the material of the produced rods, intended for further research. Mechanical and microstructural investigations will be supplemented by in-vitro biodegradation analysis in a simulated environment of the human body. This will ensure the full comprehensiveness of the investigations carried out on the designed and produced Zn-Ag alloys.

Keywords: micropollutants, swimming pools, Pharmaceuticals and Personal Care

Products (PPCPs).

Different pollutants and chemical contaminants enter swimming pools. They can affect human organisms in various ways, what should be considered as a potential threat to the health of swimmers. They may also interact with one another, transform or degrade. The knowledge of the susceptibility of micropollutants present in swimming pools to these processes and factors affecting their intensification may lead to development of a method allowing the effective elimination of these compounds from swimming pool water environment. This work is a preliminary study to determine the transformation paths of small-molecule organic micropollutants in swimming pool water treatment systems and thus to understand the physical changes and chemical reactions of various compounds that may occur in these systems. This study was carried out on the example of selected compounds from the group of Pharmaceuticals and Personal Care Products (PPCPs). Researches on PPCPs in swimming pools are still in their infancy and available data are limited, while PPCPs are designed to be biologically active even at low concentrations and the long-term exposure to their mixture may potentially lead to negative health effects. Moreover, their degradation in swimming pool systems may lead to formation of by-products that have greater influence to the health of swimmers than their maternal compound. The extensive knowledge of the occurrence of PPCPs and their by-products in swimming pool water is essential as the swimmer body is indirectly exposed to water containing these chemical substances. They may be ingested, inhaled, or absorbed by swimmers.

The impact of milk processing plant production profile on dairy sewage composition

Paweł Popko1,*, Joanna Struk-Sokołowska1

1 Białystok University of Technology, Faculty of Civil and Environmental Engineering, Department of Environmental Engineering Technology and Systems, Bialystok, Poland

Keywords: dairy, milk processing plant, wastewater, production profile

Dairy industry is one of the biggest sources of industrial wastewater in Europe. The problem of dairy sewage treatment is not completely solved. Dairy wastewater is characterized by high load of COD and BOD5. This includes fats, sugars and protein and shares of these substances can vary. Nitrogen in dairy sewage occurs in the form of organic nitrogen and NH4+, NO2- and NO3- ions and it’s main source are milk proteins. Susceptibility to biological degradation of substances contained in dairy wastewater depends on the type of wastewater generated in a particular milk processing plant.

The purpose of this work was to determine the variability of wastewater composition in milk processing plants depending on their production profile. Polish milk production was characterized based on geographical division into voivodeships (districts) around the country. The share of Polish milk production in the European and global economy was also determined. The region of Podlasie, which is the national milk production center and the Mazowieckie and Warminsko-Mazurskie voivodeships had special focus. The results of research carried out between 2014 and 2017 were analyzed for four milk processing plants. Dependencies between indicators of organic and biogenic contamination were analyzed in the wastewater generated from those plants. It was determined that dairy sewage discharged from differing production profile plants varied also in the physico-chemical composition. The composition of dairy sewage is primarily influenced by the plant production profile but also by specific technologies used. An example of such a technology is a closed circuit economy which allows for a substantial reduction of water and energy consumption. Regardless of production profile dairy sewage is characterized by a high COD/Ntot ratio which classifies it as susceptible to highly effective biological purification. Biological removal of phosphorus from dairy sewage should proceed with high efficiency without the need for chemical precipitation. Only in dairy wastewater from Olecko (curd, cottage cheese and yogurt not produced) the lower value of the ratio BOD/Ptot and COD/Ptot makes it impossible to achieve high biological effectiveness of phosphorus removal and an additional process of chemical phosphorus precipitation should be applied in WWTP.

Keywords: PV efficiency, dust deposition, efficiency, energy lost

Photovoltaic (PV) panels during operating generate a strong electrical field. This field attracts particulates, particles and aerosols in the air. The energy performance of photovoltaic modules are influenced by a large number of environmental parameters as air temperature, wind speed, air pollution, the angle of incident irradiation, solar radiation spectrum, snow and shadowing. One of the parameters that influence the energy conversion in PV modules which can be significant in many regions is an accumulated dust. The dust particles deposition on surface directly affects the transmittance of the solar collector and photovoltaic panels which leads to significant decrease of its performance.. In the research focused on the deposition of particulate matter on a standard photovoltaic panel working under varying environmental conditions. The effect of the dust deposition on PV performance as well as the influence of the electric field on the deposited dust mass were analysed. In order to evaluate the effect of electrical field on mass of dust deposited a specially prepared PV panel without silicon cells (and without electrical field) but characterized by identical glass surface construction were used in parallel to standard construction. Only that allowed to analyse dust deposition on PV panel with and without electrical field. During the project a numerical analysis of solid particles deposition on the surface of panels was conducted. In the literature this type of analysis is not available. One of the reason is that the PV panel always produces an electric field during its working and it is not possible to shut down this effect under normal operation

Keywords: air pollution; PM 2,5; PM 10, statistical analysis

This article analyses the influence of meteorological conditions (air temperature, wind speed, humidity, visibility) and anthropogenic factors (population in cities and rural areas, road length, number of vehicles, dust emissions, gases and coal consumption in industrial plants, number of installed devices to purify air from industrial plants) on the concentration of PM 2.5 and PM 10 in the air in the Świętokrzyskie Voivodeship [1,2]. In order to assess the relationship between the independent variables mentioned above and the air quality indicators, Sperman's correlation coefficient was determined. The calculations showed significant statistical dependencies between the air quality and the number of installed air purification devices in industrial plants [3]. A statistically significant influence of population in rural settlement units on the increase of concentration of PM 2.5 and PM 10 in the air was also found, which may confirm a significant influence of the so-called low emission on the air quality in the Świętokrzyskie Voivodeship [4]. The analyses showed a significant statistical impact of road length on the decrease of PM 2.5 and PM 10 contents in the air , which indicates that the decrease in traffic intensity on particular road sections, and thus an increase in the speed of vehicles, leads to an improvement in air quality. The analyses showed that despite the increasing anthropopressure in the Świętokrzyskie Voivodeship, air quality with respect to PM 2.5 and PM 10 contents is improving.

At the moment, more and more renewable energy sources are used in the energy industry. One of them is solar radiation, which is converted into electricity by photovoltaic (PV) cells. This paper presents the results of PV cell simulations with additional layers of ZnO nanoparticles and rare earth elements. The layer's task is to convert ultraviolet light into visible light, which is better used by photovoltaic cells [1]. Two physical phenomenas: down-conversion or down-shifting are used to achieve this effect.

The traditional photovoltaic cell has a poor response in the ultraviolet spectrum [2]. One of the ways to increase the efficiency of photovoltaic cells is to use the of ultraviolet spectrum. Down-conversion and down-shifting phenomenas are applied to use this spectrum. Down-conversion consists in absorbing a photon with higher energy and emission of two identically energetic photons, whereas in down-shifting process only one. In other words, the conversion of ultraviolet light to visible light is carried out in both cases. There is also a third, up-conversion phenomenon, dealing with the conversion of infrared radiation to visible light. The up-conversion phenomenon consists in the absorption of two low energy photons and the emission of one photon with higher energy [3]. The SCAPS (Solar Cell Capacitance Simulator) program [4] and the results of previously measured powder of zinc oxide and rare earth elements were used to carry out the simulation. Silicon cells, cadmium telluride and CIGS models were used for the simulation. After performing the simulation and analyzing the results, one can notice the evident influence of ZnO nanoparticle and rare earth elements on the improvement of photovoltaic cell operation. In each of these cells the current density increased and the efficiency increased. This is evidence that the UV light has converted to visible light, which was used by cells.

Keywords: acoustic power, classical guitar, modular guitar, musical acoustics, sound

hole

Sound generation in string instruments is a complex phenomenon. Although musical acoustics is a developing field of science, mathematical models and simulations of instruments behaviour are still significantly simplified, what makes an exact prediction of specific constructions’ effect impossible. Therefore, luthiers’ work is still based mostly on intuition and experience of former generations. Luthiers engaged in making classical guitars have different opinion on the influence of particular construction elements on final instrument tone and power. The aim of the project was to point the specific relations between the type of a sound hole and the acoustic power of the classical guitar.

In the project, a new objective measuring method was introduced. Its main asset is a special measuring instrument – the modular guitar. Its elements are replaceable and adjustable, what enables to determine the influence of particular construction elements on the acoustic parameters of the instrument. During the study, three different types of sound holes were compared, regarding their influence on the acoustic power of the guitar. The results of the research were compared with the general opinion on the subject of the guitar makers and players communities. Undertaken approach can significantly broaden the general knowledge about classical guitar and contribute to its development, as the classical guitar is an instrument which still evolves.

In 2017 the students of master degree in Department of urban planning and design of Lviv Polytechnic National University participated in the national urban competition “The renewal of the public space at The Independence Square in Khmelnitsky”(03.08-23.11). The purpose of the competition was to create unified, integral vision and complex approaches to solve the problems to improve the quality of urban environment, the persistence of memory and the development of cultural activities. The jury highly appreciated the proposals of the students and directed it to realization.

Concept I. Authors: Mambetova Selma, Ibrahymov Alim, Peleshchuk Olha, 1st place. The concept was to design balanced area, using the entire territory. Project was based on the dynamic form of pedestrian green alley and bicycle path. The memory function was reflected in the monumental sculpture. There is Veche Square in front of Khmelnytsky State Administration and it’s space continues in two dry fountains. The fountains work in spray mode, creating fog and jets of water. The multilevel idea with ECO-alley is united in ‘wave’ - the transfer of vibrations, providing a logical structuring to the square and expanding the limits of its application to the whole city. The main accent of the square will be light installation, which project during the whole day and night names of those who laid their lives for the preservation of our Independence.

Concept II. Authors: Snihur Anastasiia, Slobodianiuk Roksolana, 2nd place. The idea was to create physical area that will provide permanent interaction of different social groups during the year in order to improve the living conditions of the city. Quality area with different functional content will help city to interact with different social and age groups. Memory function will be interpreted as an element of pride and will form an interactive Gallery of Memory, that would be actively used and it will promote the ideas of the Revolution of Dignity.

The Numerical Methods for Identification and Analysis of Elektroencephalographic Signals

Justyna Sokołowska1,*, Jarosław Zubrzycki1, Magdalena Marchewka1

1 Lublin University of Technology, Mechanical Engineering Faculty, Department of Biomedical Engineering, Lublin, Poland

Keywords: elektroencephalography, numerical methods, wavelet transform

Human body is a living generator of bioelectric signals. One of the most commonly recorded and processed signals is electrical activity of heart, muscle, eye or brain. Electroencephalogram is a record of changes in the electromagnetic field. The main field which is dealing with the application of encephalography is the diagnosis of epilepsy. The consequence of epilepsy is significant systemic disorder so it is really important to diagnose this disease as soon as possible. Analysis of the raw EEG signal is difficult for an untrained neurologist so the numerical analysis comes to rescue.

The paper presents possibility of using some of the digital signal processing methods. Thanks to them comparison of EEG signal of the healthy person and of the person suffering from epilepsy becomes easier. The research was conducted in Lublin University of Technology, using HydroCel Geodesics Sensor Net grid with 32 active electrodes. EEG records of female patients aged 7-15 years with clinical epilepsy and healthy female aged 22 were used. The main tools used are Fourier transformations (DFT, FFT, STFT), wavelet transform and Hilbert-Huang transform. Signals from individual electrodes were integrated. Next, Matlab FFT spectral analysis was used, separately for between-seizure waveform and for the seizure waveform. Then using Svarog program, Morlet Wave module we obtained time-frequency spectrum.

When analyzing wavelet spectrograms, we can obtain information which frequency is dominant, its amplitude and the distribution over time, which allows us to accurately determine when the epileptic attack starts and how long it will last.

The methods mentioned can be helpful in creating mathematical algorithms for detecting and identifying irregularities and then to alert medical staff.

Keywords: mobile payment, mobile technology, customer perception, smartphone,

technology

Aiming to investigate the relationship between consumers’ perceptions on use of payment technologies, this study consists of four specific objectives: 1) to identify the customers’ perceptions around payment technology in food and beverages industry; 2) analyze satisfaction level and its influence on consumer loyalty in the food and beverage industry; 3) identify critical success factors in customer-driven payment technologies deploying; and 4) relate the perceptions of payment technologies’ use to customer satisfaction. The mobile technology for payment topic is new in Brazil, despite the high diffusion of several kinds of mobile devices, beyond smartphones, such as watches and cards with NFC technology (Near Field Communication). Observing this phenomenon, in the initial stage of implementation in the food and beverage industry, the present study sought to describe the state of the art and articulate experiences in the literature from inside and outside the country. A survey had been held seeking to understand this global phenomenon and the impact of technology application in food and beverage industry in Brazil on customer satisfaction; in which 950 respondents were inquired, 738 answered the questionnaire in full (77.68% of questionnaires), the respondents' average age is 35 years, and reached 26 states of the federation, having a significant sample in terms of population. Based on those answers, we seek to confirm or refute, through statistical analysis, the following hypotheses: H1 - Restaurant costumers' prefer establishments that adopt mobile payment technology in their service experience, H2 - Costumers perceive a better level of service, information and entertainment in service experience in restaurants that adopt mobile payment technology, H3 - The use of payment technologies acceptance can vary depending on its profile of the costumer, H4 - The use of payment technologies positively influences the perception of the costumers on satisfaction, convenience, exploration, precision and speed of delivery, H5: The use of payment technology negatively influences costumers' perception on need for human interaction in restaurants, H6 - When customers rely on payment technologies, the need for human interaction is decreased. We analyzed and categorized the collected data among factors that affect the perception and satisfaction of using mobile payment technologies in restaurants, and the quantitative study also allowed to understand which factors have the major impact on the perception and use of mobile payment technologies, identifying a set of relevant factors, as well as finding the advantages and disadvantages expected by costumers in the use of mobile payment technologies.

1 Poznan University of Technology, Faculty of Electrical Engineering, Institute of Electrical Engineering and Electronics, Division of Mechatronics and Electrical Machines, Poznan, Poland

Keywords: Inverter, DDS method, PWM method, high-frequency, pure sine-wave

In today’s world, the construction of inverters requires more and more complex modulation methods and circuit designs to ensure high flexibility and quality of output waveform. The purpose of this work is to elaborate an inverter with a wide regulation range of output and switching frequencies. In order to meet this goal, an improved, fully digital modulation method combining advantages of the PWM method and the DDS method has been developed and some structural improvements have been introduced. As compared to conventional methods, combination of the DDS method with the PWM method ensures high level of flexibility and simplifies significantly the control circuit because of the lack of any external analog device and no need of using a reference signal. To construct the transistor H-bridge with wide regulation range of the switching frequency, p-channel MOSFET transistors, controlled by voltage dividers, have been used. The influence of

a frequency and amplitude change on output waveform was verified by feeding loads of different factor and registration of the distortion. Obtained results have been analysed by means of FFT. It has been shown that in specified range of the output frequency the THD factor value of obtained waveforms is very low. This paper presents an application of elaborated and constructed single-phase inverter with the frequency regulation of output waveform up to 1 kHz, however, it should also be noted that the inverter using designed modulation method can easily work with the output frequency up to 90 kHz, therefore can be used as a supply for a Wireless Resonant Energy Link System (WREL) [5].

Kinga Michalec1,*, Anna Kusior1

1 AGH University of Science and Technology, Faculty of Materials Science and Ceramics, Department of Inorganic Chemistry, Krakow, Poland

Keywords: iron oxides, nanostructures, photocatalysis, hydroxyl radicals

There are sixteen known ‘iron oxides’. This term refers to a group of oxides, hydroxides and oxide hydroxides. Of all iron oxides, hematite (α-Fe¬2O3) has a number of properties that make it a promising photocatalytic material. It is one of the most stable transition metal oxides under ambient conditions. It is an eco-friendly and an inexpensive n-type semiconductor. It has been proven that the physicochemical properties of crystals are strongly dependent on their morphology. The configuration of surface atoms and the presence of hydroxyl groups play a significant role in determining the photocatalytic properties of iron oxides. The research includes the synthesis of nanostructures based on iron oxides with various shapes (nanocubes, nanodiscs) via metal-ion mediated hydrothermal route. The aim of this work was to analyze the influence of morphology, ‘amount’ of surface hydroxyl groups and addition of H2O2 on the photocatalytic properties of synthesized nanopowders. The obtained nanomaterials were characterized by using Scanning Electron Microscopy, X-ray diffraction, UV–VIS–NIR spectroscopy, Fourier transform infrared spectroscopy and Zeta-potential measurements were carried out. Furthermore, photodegradation of Rhodamine B was examined in aqueous solutions under visible light irradiation at room temperature.

The use of 3D printing technology for the production of copper parts

Kinga Skrzek1,*

1 University of Technology and Humanities, Faculty of Mechanical Engineering, Radom, Poland

Keywords: copper, 3D printing, production

Currently, the use of manufacturing technology based on 3D printing (metal printing) has become extremely popular. The last year saw an increase in the use of this technology in the industry by 20%. The advantage of copper as a construction material, in addition to high electrical and thermal conductivity is a strong antibacterial effect. Therefore, it is widely used in the energy industry, refrigeration and medicine. For the production of copper parts in 3D printers, copper is used as a powder. Currently, 3D copper printing methods are a method of selectively fusing the laser layer with laser beam (SLM) and the electron beam melting (EBSM) powder layer method. However, due to the partial reflection of laser light through copper and the high thermal conductivity of copper, it is difficult to obtain the required powder melting temperature. For these reasons, the powder used in 3D printers must meet high requirements. Preliminary literature studies show that the production of spherical copper powder with a grain diameter in the range of 20 to 160 micrometres should be considered. These requirements can be achieved by perfecting typical methods of producing metal powders.

In the article, based on a literature analysis, the requirements for copper powders as a material in 3D printing technology were presented and typical methods of producing metal powders were described. The conclusions set out a method for the production of metal powders, with the use of which copper powders with the required characteristics can be produced with sufficient production efficiency.

Keywords: Integrated Gasification Combined Cycle (IGCC), Thermodynamic analysis,

Gasification

The future development of the energy conversion systems is considered to be based on second and third generation technology. One of the most innovative designs is the Integration of Coal Gasification Systems with a Gas Turbine Combined Cycle (Integrated Gasification Combined Cycle – IGCC) [1,3]. Such a system may constitute a very appealing solution to be implemented especially for the future use of hard and brown coal.

Gasification may also be one of the best ways to produce clean-burning fuel for tomorrow’s cars and power-generating fuel cells with additional production of syngas, ensuring the lowest level of the emission of CO2.

In the present paper, a thermodynamic analysis of the Integrated Gasification Combined Cycle coupled with a coal drying system (IGCC-CD) for electricity production is discussed [2]. The proposed system is able to generate electricity with a thermal efficiency which is higher than in any conventional system as well as it gives the opportunity to decrease air pollution and to reduce fuel (coal) consumption. The system consists of seven dependent sub-systems: Fuel preparation (Lignite Drying), Air Separation Unit (ASU), Coal Gasification, Gas cleaning system, Gas Turbine, Heat Recovery Steam Generator system, Steam Turbine, and Regeneration system for highly efficient electricity production.

Vacuum treatment of activated sludge

Kinga Pogoda2, Anna Gnida1,2*

1 Silesian University of Technology, Environmental Biotechnology Department, Gliwice, Poland 2 Silesian University of Technology, Biotechnology Centre, Gliwice, Poland

Keywords: activated sludge, degasification, nitrogen concentration, vacuum

Reduction of pressure (vacuum obtainment) for a short time can be used for degassing of activated sludge while wastewater treatment. Degassing is performed before discharge of activated sludge to secondary clarifier and improves the settling properties of activated sludge. During the degasification the activated sludge flocs are believed to be destroyed due to gas bubbles escaping the mixture and reflocculated suddenly after the pressure above the mixed liquor is atmospheric. The physical process of degasification is based on change in solubility of gases and used to remove gas bubbles and decrease mainly nitrogen concentration in the mixed liquor. The process is known to enhance the nutrients removal efficiency during biological wastewater treatment, but the mechanisms are not fully recognized.

The aim of the research was to determine the effect of negative pressure on concentration of nitrogen while degasification of activated sludge.

The activated sludge was affected by several different values of vacuum and different durations. Among few other parameters describing activated sludge a concentration of total nitrogen was analysed in activated sludge and filtered mixed liquor to determine effect of vacuum on nitrogen removal. The results were compared with vacuum extend. Acknowledgements The research was financed by the Polish National Research Centre under project entitled “Assessment of low vacuum effect on bacteria, activated sludge and wastewater treatment efficiency” (project no 2013/11/D/NZ9/02608).

Voltammetric determination of thiamine

Radosław Porada1,*, Bogusław Baś1

1 AGH University of Science and Technology, Faculty of Materials Science and Ceramics, Department of Analytical Chemistry, Krakow, Poland

Keywords: voltammetry, vitamins, thiamine, signal processing

The term vitamins describe a heterogenous group of chemical compounds, essential for proper functioning of human body and its metabolism. Based on their solubility they are usually divided in two groups. One of them includes fat-soluble (A, D, E, K) and the other water-soluble vitamins (B-group and C). Vitamin B1, also known as thiamine, is a key constituent for our nervous system and therefore its deficiency leads to multiple symptoms, such as weight loss, anorexia, impairment of motoric system and chronic disease called beriberi. By definition, vitamins are not produced by the body, hence an appropriate supplementation with dietary ingredients is of the essence. Because of that it is also vital to develop new methods, which allow for quantitative determination of vitamins in food sources and pharmaceuticals. For thiamine currently the most popular one is based on a thiochrome reaction, but this method is susceptible to interferences and requires a time-consuming sample preparation. This paper is devoted to the development of an electrochemical methods for thiamine determination. The influence of the buffer type, its concentration and pH-value, alongside with parameters for differential pulse adsorptive stripping voltammetry (DP AdSV) were taken into consideration and as a result the 0,1 mol·L-1 acetate buffer in company with a set of instrumental parameters, which allow for high sensitivity of the developed method, were chosen. Furthermore, the calibration curves were made, based on which the linear range and limit of quantification were calculated. By means of the cross-validation technic statistical significance and predictive capabilities of the obtained model were confirmed. Finally, the possibility to apply some numerical algorithms for signal separation in order to determine the thiamine concentration in presence of interferences was checked.
