WELCOME TO ICAMMEN 2018

Dr. Mostafa Ranjbar Scientific Chairman Ankara Yıldırım Beyazıt University

Dear valuable scholars, as the scientific

chairman of ICAMMEN2018, it is my ultimate

pleasure to welcome you sincerely to our

conference. Me and my conference team are so

excited to see you all here in Ankara. Ankara is

the capital city of Turkey. In this city, there are

several top-level state and private universities,

research and industrial companies. Also, there

are several others around the Ankara. They

need to be connected locally and internationally. Therefore, ICAMMEN2018 has been

established to provide a platform for such important and strategic scientific interaction in local

and international levels. ICAMMEN 2018 has prepared to host scholars from the Turkey,

neighbors and other countries to show their latest advances in mechanical and mechatronics

fields in the highest level. We announced the first conference call in June 2018. Five months

is a very short time to arrange such international conference. However, we faced with an

unbelievable and prominent level of interests from Turkish and international colleagues. In a

couple of months from the announcing of conference, we are proud to indicate that we got

almost 200 good submissions from more than 400 authors from around 30 different countries

in five continents like, Germany, USA, Canada, Columbia, Peru, Ecuador, Brazil, France, Italy,

Portugal, United Kingdom, Slovenia, Slovakia, Hungary, Algeria, Ghana, Cameron, Nigeria,

India, Iran, Iraq, Kuwait, Qatar, Saudi Arabia, Pakistan, Thailand, Malaysia, and Australia. Also,

we received very good quality submissions from top rooted Turkish universities and industries

like Middle East Technical University, Istanbul Technical University, Yıldız Technical University,

Hachette University, Gazi University and all other universities that I cannot mention them

here. We have also some valuable researchers who will present their latest studies from big

companies like TOFAŞ, TUSAŞ, MAN, MKE, AVL and Valeo. At least 100 papers will be

presented in the parallel technical sessions on solid mechanics, thermofluid/energy,

manufacturing and material engineering during today afternoon and tomorrow morning.

With all this background, I wish you all a very beneficial conference and to make long term

collaborations with each other’s.

students with a good international student ratio in 8 different departments which are

Electrical and electronics engineering, Computer engineering, Mechanical engineering,

Material engineering, Civil engineering, Industrial engineering, Energy systems engineering

and Mathematics. We have 142 academic staff. Furthermore, we have several foreigner

academic members in our faculty. Furthermore, we are offering MSc and PhD programs in 5

majors including Electrical and electronics engineering, Computer engineering, Mechanical

engineering, Material engineering and Energy systems engineering to more than 700 graduate

students.

AYBU as a state university which is in the capital city of Turkey, we are aiming to take a key

role in research & development, manufacturing and defense technologies by using of being in

Ankara which is the capital city and the hearth of the Turkish defense industries.

Currently, we have focused on the multidisciplinary engineering fields. Several newly defined

courses in the department of mechanical engineering are available for the first time in the

region. Also, we are doing our best to be the pioneer of design and development of the new

generation of Auxetics Structures and Metamaterials in the Turkey and the middle east.

Furthermore, we are aiming to expand our regional scientific and industrial cooperation with

our neighbor countries. This can be very beneficial for the region. Developing of joint national

brands in various engineering fields is our wish.

ICAMMEN2018 can be a good platform for beginning of such local and international

cooperation. I hope that you enjoy from ICAMMEN2018 and wish you a pleasant stay in

Ankara.

Prof. Dr. Metin Doğan Honorary Chairman & Rector of Ankara Yıldırım Beyazıt University

Dear Ladies and Gentlemen.

I would like to welcome you all to our

university. Although Ankara Yıldırım Beyazıt

University is a newly established institution, it

has managed to be a center of attraction for

the academicians who are true professionals in

their fields and has attracted the attention of

successful students. The experienced, active

and dynamic academic staff of Ankara Yıldırım

Beyazıt University is mostly consisted of academicians who have obtained their

undergraduate/graduate degrees from the pioneer universities of USA, Europe and Turkey.

With almost 500 faculty members and more than 1000 academic staff in total, the university

has managed to advance its academic human resources perfectly. Also, the university attracts

attention of the students of high quality by offering English education. Furthermore, the

university has been taking significant steps to position itself among the pioneer universities.

At this regard, the undergraduate placement examinations result show that AYBU is placed

within the first 5 in the university preferences among the Turkish universities. The university

vision is to become a pioneer not only in Ankara or Turkey, but also in the world.

Our aim is to expand the scientific cooperation with our neighbor countries to establish an

ecosystem for research and development and economic progress of this region which has a

population number even more than European union. This can be done by developing joint

industrial projects to develop joint national brands in various sections of engineering so that

the people of our country and region can use them with a lower price and higher quality. We

believe in developing of regional economy by developing scientific and industrial ties. In fact,

together we are stronger.

Thank you very much for your attention and wish you a successful conference.

KEYNOTE SPEAKERS

Prof. Dr. Steffen MARBURG

Technische Universität München, GERMANY

The research interests of Steffen Marburg (b. 1965) encompass the development

and application of numerical methods for vibroacoustics and aeroacoustics, the

experimentally based virtual prototyping of complex models in combination with

parameter identification, the consideration and identification of parameter

variations and structural acoustic optimization. The applications are manifold and

include automotive parts, ships, electric tools and musical instruments. Marburg

graduated from TU Dresden where he was awarded a doctoral degree in 1998. He

became a junior professor for Structural Acoustic Optimization/Boundary Element Methods in 2004. In 2010 he

moved to the University of the Federal Armed Forces in Munich and became a full professor for Technical

Dynamics. In 2015 he was awarded the new professorship for Vibroacoustics at TUM. Marburg is associate editor

of the peer-reviewed journal Acta Acustica united with Acustica, editor of the Journal of Computational Acoustics

and chair of the TC Computational Acoustics of the European Acoustics Association.

Keynote Speech: From Axioms of Continuum Mechanics to Quiet Structures - A Brief Survey of

Vibroacoustic Modelling and Optimization

This talk will discuss the ingredients of simulation of low–frequency structural acoustic problems. Low

frequency problems are defined in terms of the wave number and thus, assumes that only a limited

number of waves is counted in the computational domain. Usually, a low frequency problem assumes

normalized wave numbers kL < 30...100 with k as the wave number and L as a characteristic length of

the model. It is a weak assumption though. Often, low frequency acoustic problems are understood as

purely deterministic, whereas high frequency problems are seen as non–deterministic and hence,

statistic problems. This presentation will survey vibroacoustic modelling, model adjustment and model

optimization. For this, modelling starts with the axioms of continuum mechanics in which linear

elasticity is assumed for structures and fluids are compressible and lossless. Interaction between

structure and fluid is formulated by two interface conditions. Since an analytical solution is only

possible for a limited number of simple cases, industrially relevant problems are usually solved

numerically, usually by using finite and boundary element methods, i.e. FEM and BEM. In many cases,

it is easy to yield an accurate numerical solution. However, practical problems require knowledge of

model parameters which account for the major problem in structural acoustics. Material parameters,

parameters of joints and boundary conditions are often difficult to determine accurately and,

additionally, exhibit different kinds of uncertainties. Parameter adjustment requires experimental

investigations such as modal analysis. When finally arrived at a suitable simulation model, the results

need to be assessed. For this interior and exterior problems are distinguished. While interior problems

are often assessed based on local quantities, e.g. sound pressure at one or a few points, the radiated

sound power accounts for a suitable quantity for exterior problems. Simulation models are optimized

by minimizing an objective function to find a (much) better design than originally available. Throughout

this talk, most of these steps will be presented together with different academic and industrial

applications.

Keynote Speech: Texturing of Alloy Surfaces Towards Self Cleaning Applications

Texturing of surfaces remains critical for self-cleaning applications. In the present study, laser gas

assisted and repetitive pulse treatment of Ti6Al4V alloy surface is presented. The resulting surface

texture characteristics and wetting state are analyzed using the analytical tools. The surface energy of

the laser treated surface is determined adopting the contact angle method. It is demonstrated that

laser repetitive pulse treatment results in hieratically distributed micro/nano pillars. The wetting state

of the laser treated surface remains hydrophilic because of the large gap size between the micro/nano

pillars. The surface free energy of the laser treated surface is similar to that corresponding to the TiN

coated surfaces, which is attributed to the nitride compounds formed during the laser treatment.

modeling and identification of nonlinearities in dynamical systems. Professor Younesian has recently focused in

application of nonlinear systems in vibration energy harvesting. He has authored or co-authored over two

hundred publications including four books, journal articles, monographs, reports and conference papers.

Keynote Speech: Application of Multi-Stable Systems in Broad-band Vibration Energy Harvesting

Performance and characteristic behavior of different types of multi-stable systems in vibration energy

harvesting is presented in this talk. A universal mechanism is introduced to provide diverse types of

the broad-band energy harvesters. A short review of the new achievements and applications of the

multi-stable systems is addressed. For a typical design, numerical results are presented for

monochromatic and irregular wave regimes. Over a parametric study, effects of different design

parameters including the power take off coefficient and characteristics of the restoring system on the

efficiency of energy harvesting device are evaluated. It is shown how and in what extent, bistable and

tristable systems can enhance the capture width ratio of the conventional point absorbers. It is shown

that robustness of these two multi-stable systems with respect to the frequency and damping off-

tuning is quite significant.

Doc. studies. He is an Associate member of Turkish Academy of Sciences.

Keynote Speech: Mechanical Properties of Polymer / Bioceramics Based 3D Porous Scaffolds in Hard

Tissue Engineering

In recent years, significant progress has been performed in designing and producing polymer/ceramic

based 3D porous scaffolds for hard tissue engineering applications. Conventional metals used in hard

tissue applications currently are unsatisfactory due to density and mechanical mismatch between the

implant and the hard tissues. Therefore, metal implants with higher mechanical strength than bone

result in stress shielding. Moreover, some components of these materials might be toxic under in-vivo

conditions. Polymer/bioceramic composites are currently investigated to solve the problems arising

from the conventionally used biometals. This study investigates the contribution of pore parameters

(Total porosity, pore size, pore distribution, pore morphology) on mechanical characteristics of

scaffolds for hard tissue applications.

Institute, Troy, NY, USA in 2002. Before joining the TAI, he has worked in universities

and industry for many years. He is also jointly working in the Mechanical Engineering

Department at Ankara Yıldırım Beyazıt University, Ankara, Turkey.

Keynote Speech: Composite Applications in Aerospace Industry

Combinations of lightness and performance (high strength, toughness, product life etc.) of

aerostructures are extremely important in aerospace industry. Composites materials are key

candidates to satisfy lightweight and exceptional mechanical properties requirements. Complex parts

can easily be produced by using different manufacturing methods. The advantageous of the parts help

reduce number of parts, fasteners, and the assembly time in aircrafts. In recent years, the use of

composite materials in aerospace industry have been increased gradually. Previously they are mostly

used as secondary parts now they are highly used for primary structures such as fuselages and wings.

Nowadays, more than 50% of some commercial aircrafts parts are composites. In near future, it is

expected that the ratio will be increased more. In this present study, the applications of composite

materials in aerospace industry will be summarized and discussed.

ABSTRACT

In physical therapy and rehabilitation, studies on intelligent robotic systems developed

with artificial intelligence have gained momentum in recent years. The contribution of

robots to the treatment process has been demonstrated in many studies, both in the

laboratory environment in which they have been developed, and in clinical trials.

However, studies on the use of robots in diagnosis are limited. The use of robotic

systems for diagnosis with the support of intelligent control structures can provide

significant contributions to experts working in this field. The limb size must be

measured during the diagnosis. In the treatment process, the size of the limb must be

known so that the robot manipulator can be adjusted according to the limb of the

patient. The automatic measurement of these required measurements with the help of

a device will contribute to the ability of robots to carry out the diagnosis and treatment

process themselves. In this study, we developed a device that can automatically

perform forearm peripheral measurements used for diagnostic and therapeutic purposes

in rehabilitation robots. The device automatically measures arm length and arm

diameter. For this purpose, infrared distance sensors and a linear motion system that

allows movement along the arm are used. The data of the measurements made are

displayed on an LCD screen and stored in the computer environment.

Keywords: peripheral measurement, robotic rehabilitation, upper limb

ABSTRACT

The smart materials have been used for decades in several applications because of their shape changing, actuating and

many other novel properties. Shape memory polymers are a class of smart materials and both thermoset and

thermoplastic based polymers can be utilized as shape memory polymers.

These materials have a large recovery strain rate compared to shape memory metal alloys. Besides that, high corrosion

resistance, low density and electrical and thermal insulation are some of the features of shape memory polymers. Shape

memory polymers change their shape by an external stimulus and this stimulus for shape memory materials is done by

heat. These materials are smart materials in such a way that they have the ability to memorize their original shape after

they change their shape by heat.

In this experimental study a biocompatible polyurethane based shape memory polymer which has a glass transition

temperature (Tg) of 35 °C has been studied. The first desired aim was to obtain the optimum casting and curing

processes. After this achievement, mechanical and thermal characterizations of this material were carried out. The heat

was applied to shape memory polymer to activate shape memory effect of material in this study. Three point bending

testing was carried out to obtain Young Modulus in bending and DSC thermal characterization was carried out to obtain

Tg of the material. The results of the three point bending testing showed that Young Modulus in bending showed

variations and some of the results were higher than the values given by the manufacturer. The authors noticed that the

variations in the results are due to the low Tg of the material hence Tg of the material is close to the room temperature.

DSC analyses showed that the obtained results of the Tg of the material are in agreement with the manufacturer’s value

which is 35 °C.

Keywords: Shape memory polymers, shape memory effect, smart materials

ABSTRACT Whilst there are numerous investigations and comprehensive reviews on circular or square cylinders in tandem, flow structures behind normal flat plates in tandem have attracted limited investigations. One reason could be that this geometry has fewer number of industrial applications comparing to other bluff bodies. Hence, still unidentified flow structures and vortex street formation mechanism in the wake region has remained unstudied. The previous studies on two normal flat plates in tandem, focused on the wake structure by employing the classical Reynolds decomposition. However, in this study vortex shedding from two identical normal flat plates in tandem has been investigated by employing the triple decomposition technique. In this study, flow structures behind two identical normal flat plates in tandem arrangement have been investigated for various gap ratio (g/D) between the plates at high Reynolds number of 3.3x104. Constant-temperature hot wire anemometers (CTA) have been employed to measure the near wake properties behind the downstream plate quantitatively. The effects of various gap ratio (g/D) ranging from 0.2 to 2.0 on the velocity components have been probed and presented. It was found that as the gap between plates increases, the peak values of streamwise and transverse velocity components decrease due to entrainment of fluid into the gap. Moreover, comparison between the wake region behind single plate and tandem plates demonstrated a reduction in peak values of streamwise and transverse velocity components behind flat plates in tandem arrangement.

ABSTRACT

A commercial SiO2-Al2O3-CaO based glass at 20 wt% (G-20), 40 wt% (G-40), 50 wt% (G-50), 55 wt% (G-55), and 60

wt% (G-60) was added to Al2O3 to determine composite compositions for specific applications such as low temperature

co-fired ceramics (LTCC) and radome. Densification, phase formation and characterization of dielectric, mechanical and

thermal properties were studied. The optimum densification temperatures were determined to be 1350°C for the G-20,

1200°C for the G-40, and 850°C for the G-50, G-55 and G-60. Anorthite crystallized after 825°C in all composites.

Young’s modulus decreased from 231 GPa for the G-20 to 105 GPa for the G-60. Flexural strength ranged between 387

MPa for the G-20 and 213 MPa for the G-60. Similarly, hardness and fracture toughness were 1058 HV, 4.5 MPa.√m for

the G-20 and 679 HV, 1.9 MPa.√m for the G-60. Dielectric constant and dielectric loss of the composites (G-20 and G-

60) at 5 MHz were 8.76-7.32 and 0.0022-0.0081, respectively. Thermal conductivity and thermal expansion coefficient

decreased with increasing glass content; 1.25 W/m.K, 7.06 ppm/°C for the G-40 and 0.98 W/m.K, 6.66 ppm/°C for the

G-60, respectively. For LTCC applications, the G-50 to G-60 composites were proposed due to lower sintering

temperature, lower dielectric properties together with moderate mechanical and thermal properties. The G-55 composite

was successfully fabricated by tape casting. For radome applications, the G-20 and G-40 composites were proposed due

to lower density, higher sintering temperature, lower Young’s modulus and thermal expansion coefficients.

ABSTRACT

Gel casting is a colloidal processing route to produce large and 3D complex products. It was aimed to investigate gel

casting of mullite because this method has not been studied to produce dense mullite in literature. Mullite was chosen due

to its excellent creep and thermal shock resistance at high temperatures. Gel casting parameters such as monomer types,

their ratios, effect of initiator and catalyzer were studied. Densification behavior, dielectric, mechanical and thermal

properties were characterized in detail for radome applications. Initial mullite powder had 5-10% glass phase and 1 %

corundum. Ball milling for 48 h decreased mean particle size from 3-5 m to 0.28 m. 3.4 wt% nano TiO2 (e.g., 21 nm)

was added to form a liquid phase to aid densification. Gelation of the slurries was completed in 3 to 5 minutes at 25°C

for the samples with catalyzer and in 35 to 65 minutes at 70°C for the samples without catalyzer. All samples reached to

the relative densities of 97 to 98.2 % after sintering at 1540°C for 2 h. Backscattered SEM images revealed anisotropically

grown mullite grains, glassy phase located as islands between the grains, hexagonally-shaped Al2O3 grains and pores with

sharp corners. All samples had hardness values between 1077 HV to 1089 HV, and fracture toughness values between

2.4 to 2.5 MPa. √𝑚. Finally, a large block (240x250x35 mm3) was successfully casted, then easily machined to the desired

shapes.

ABSTRACT

Al2O3-glass (20 wt%) composites were fabricated via dry pressing method, and then mechanical and electrical

characterizations were completed for a possible radome application. EDS analysis showed that the commercial glass

composition was 67.7 wt% SiO2, 15.6 wt% Al2O3, 10.7 wt% CaO, 4.8 wt% Na2O and 3.2% K2O. Specimens were sintered

at 800-1450℃. Based on the zero apparent porosity as determined from Archimedes’ method, the optimum sintering

temperature was determined to be 1350°C and bulk density was 3.37 g/cc. X-ray phase analysis indicated that anorthite

phase appeared at temperatures above 900°C. After 1350°C, however, crystalline peaks of anorthite disappeared due to

volatilization of Na2O and K2O in the glass composition. Specimens for 3-point bending and elastic modulus were pre-

sintered at 800°C to polish to the required dimensions and then sintered at 1350℃. The shrinkage values in diameter and

thickness were 15.1 and 15.3 mm, respectively. Composites had the following mechanical and electrical results: hardness

of Hv 1096 ± 13, fracture toughness of 4.43 Mpa√m ±0.55, elastic modulus of 231 GPa ±17, flexural strength of 379 MPa

±90, In addition, dielectric constant of 8.75 and loss tangent of 0.00204 measured at room temperature and at 5 MHz.

These results suggest that this composite composition can be used particularly for radome applications due to its low

dielectric constant and loss, and density with respect to the commonly-used Al2O3ceramics.

ABSTRACT

Bioplastics such as polylactides (PLA) and polyhydroxyalkanoates (PHA) are alternatives to petroleum-based polymers

and show attractive properties such as high strength, biocompatibility and relatively high melting temperature [1,2,3].

Although PLA is one of the most popular 3D printing materials, its low ductility is a disadvantage for applications. PHA

additions can dramatically improve the ductility of PLA [4], and offers an effective way of improving the toughness of

3D-printed parts. In this study, we investigated the performance of a commercial PLA/PHA filament with ~10wt% PHA

content for Fused Deposition Modeling (FDM) applications. Dogbone tensile test specimens were printed at five different

nozzle temperatures over the range 200°C – 260°C, and tested according to ASTM 638-type 4 Test Standard. We used

X-ray Diffraction (XRD), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM) to

characterize the crystal structure and phases, thermal properties, and morphology, respectively. When the nozzle

temperature is 210°C, the elongation at failure can reach 50% for the PLA/PHA blend, demonstrating a ten-fold increase

in ductility when compared to pure PLA. On the other hand, the strength of the PLA/PHA was ~25% lower than that of

pure PLA. The results show that the PLA/PHA filaments provide a balanced combination of strength and ductility and

offer an effective solution to the 3D printing of high toughness components for applications.

ABSTRACT

We investigated the effects of annealing on the crystallinity and mechanical properties of 3D-printed PLA specimens.

Specimens with a dog-bone geometry for tensile testing were prepared by fused deposition modeling using a

commercial PLA filament. The specimens were annealed at different temperatures in the range 80°C – 120°C for

different durations (60 minutes – 24 hours) in dry nitrogen environment. X-ray diffraction (XRD) and differential

scanning calorimetry (DSC) characterized the crystallinity and the structure of the specimens. Mechanical properties

were determined by tensile testing according to ASTM D638 standard test method. Upon annealing, the disordered

crystal phase of PLA (α’) transformed into α-phase. Annealing increased the degree of crystallinity in the samples, and

higher annealing temperatures resulted in higher crystallinity. Samples annealed at 80°C for 24 hours showed superior

strength and higher ductility when compared to as-printed samples. However, annealing at 120°C resulted in reduced

ductility, comparable to that of as-printed samples. Samples annealed at 120°C experienced visible warpage due to

thermal expansion and structural changes, and the loss of ductility might be attributed to these extrinsic changes. Heat

treatments of 3D-printed components is an alternative approach to alter the structure and properties of specimens and

COMPARISON OF INVERSION MODELS FOR CHARACTERIZATION AND

UNCERTAINTY MODELLING OF RIGID FRAME POROUS MATERIALS

ABSTRACT

Study of the models regarding characterization of porous materials using numerical models (computationally), empirical

models, semi-phenomenological models and the Padé approximation-based models (or pore size distribution models)

using the more recent literature results are discussed and reviewed. It is of interest to investigate how certain and reliable

the results of such modelling and measurements actually are. Measurements using impedance tube are done on samples

of melamine foam, glass bead and silica sand. The acoustic impedance and absorption of several different stacks of such

samples were measured and the measurements were repeated, in some cases more than a hundred times. The measurement

results were used as input to several inversion codes to evaluate the performance of the methods on samples. Comparisons

are reported between the predictions of Johnson-Champoux-Allard vs Non-Uniform-Pore-Size-Distribution,

Horoshenkov et al. (2016). The parameters involved: median pore size ¯s and standard deviation in the pore size σ_s that

are measurable directly and non-acoustically; on the other hand, flow resistivity, σ, porosity ϕ, and tortuosity α_∞ are

estimated or measured. The frequency domain inverse method that is used in the study is based on an optimization

approach to reconstruct in a simultaneous manner several profiles to parameters of the material in any porous material

that is to be assumed rigid frame, one-dimensional and macroscopically inhomogeneous. As with such methods, the direct

problem is then iteratively solved by replacement of parameter values at each iteration in order to reconstruct by the

optimized values.

ABSTRACT

In this study, the “quince” grown in natural conditions in Sakarya Pamukova was dried with different drying methods.

Quinces were sliced in two different sizes as 6 mm and 15 mm and drying behavior is investigated with three different

drying methods without any pretreatment. Drying experiments; in microwave oven at 120, 350 and 700 W, in laboratory

type oven at temperatures of 105, 110 and 120 ℃ and in freeze dryer at -45 ℃, 0.352 torr. Moisture rates, drying rates

and effective diffusion coefficients of the samples taken during tests were calculated. Experiments performed in each

condition were repeated at least three times, standard deviations of the data were taken and uncertainty analysis was

performed. Experimental data were modeled by Newton, Page, Wang and Singh, Logarithmic, Henderson and Pabis, Two

terms, Midilli and Diffusion Approach drying models used in the literature. The performances of these models were

determined by calculating the correlation coefficient (R²) and square root of the mean error square (RMSE) values

between the observed and estimated humidity rates, and it was observed that the best model was the pony model with the

lowest error. The best model was determined by calculating the correlation coefficient (R²) and the square root of the

mean square of the error squares (RMSE) between the observed as Midilli model with the lowest error.

ABSTRACT

A new thermal energy storage method; thermochemical heat storage, based on reversible sorption-desorption cycles is

purposed in this study. Such thermal energy storage system could provide higher heat storage density and long-term heat

storage potential making it attractive for solar thermal applications. From this point of view, aim of the presented study

is; to develop a prototype thermochemical heat storage system and to test it under North Cyprus Climate conditions. A

novel composite sorption material; CaCl2–Vermiculite was synthesized and used as the heat storage material. Three

different cycles (discharging-charging) with the same flow rate were carried out. Throughout the testing, some optimal

results were obtained. For charging temperature between 80-90 °C, discharging average temperature lift of air between

15-20 °C was obtained. Besides, cumulative energy output in the range of 1.6-1.8 kWh was attained, corresponding to an

energy storage density between 200-230 kWh. Observed results in this experimental study demonstrated that, for both

long and short term heat storage, thermochemical process using V-CaCl2 sorbent is satisfactorily promising and a good

candidate to be utilized in solar thermal applications in buildings for sustainable space heating..

ABSTRACT

This research presents an investigation on a desiccant enhanced evaporative cooling system. In the last decade, increase

in the occupant comfort demands leads to a rising requirement for air conditioning. On the other hand deteriorating global

energy and environment crisis are starving for energy saving and environmental protection. The need to come up with the

new energy saving as well as environmental friendly air conditioning systems has been more urgent than ever before. In

hot and humid areas, the liquid desiccant air-conditioning systems based on evaporative cooling was proposed as a

promising invention. In such cycles, the desiccant decreases the air humidity which is achieved by the moisture removal

from the air. Later, reduction in the temperature is obtained by the following evaporative cooling unit..

This study illustrates a novel desiccant assisted evaporative cooling system and evaluates its performance. This study

deals with such a system and investigates vermiculite – calcium chloride as desiccant material in order to examine the

performance of the system. According to the study results, temperature drop around 10°Cwith an average cooling rate of

700 W and cooling COP in the range of 5- 6 was obtained. Economic analysis for the payback period showed that the

return on investment is 3 years for only summer operation of the system. Accordingly it is found feasible to invest on

such system in hot humid climate (such as Cyprus) for building air conditioning.

Keywords: Evaporative, Desiccant, Humidity, Cooling, Air-Conditioning.

ABSTRACT

Nowadays microfluidic chips are highly preferred in microbiology because of their micro sized structure and rapid

detecting properties. Heat generation and thermal controlling are important for some microfluidic chip process. The

electrodes are important in most of the microfluidic chip studies and also the selection of electrodes from various metals

makes researchers difficult to choose. In this study, we are investigating the development of a microheater on a chip for

bacterial lysis in order to improve the rapid and effective detection. In fact, the voltage is applied to generate the

microheater composed of the electrode material microfabricated on glass and integrated into a microfluidic channel, and

then the heat is caused to bacteria lysis travelling through the microchannel. In literature, various electrode materials are

commonly used such as aluminum, gold, silver and platinum but in general they worked at the low temperatures. Since

we need to get high temperature for our lysis, we aim to design the electrode array based on the properties of metal

electrodes. The goals of this study are to find a suitable metal electrode for the bacterial lysis to be carried out at 90-95

degrees and to make a suitable design with the help of simulation using COMSOL Multiphysics to obtain effective results.

Figure 1 displays the proposed electrode array design for this study.

ABSTRACT

Metallic bone plates are widely used in the treatment of bone fractures and there are many different types of plates in use.

Bone plates are subjected to cyclic loads during their use in human body. Also, it is known that cyclic loads can cause the

premature failure of materials under the static strength of materials and this phenomenon is called fatigue. In order to

improve fatigue properties of materials, plasma based treatments are commonly used. The main goal of this study is to

improve the static and fatigue properties of metallic bone plates made of Ti6Al4V alloy by plasma nitriding. In order to

achieve this goal, a commercially available bone plate made of Ti6Al4V alloy were plasma nitrided at 700ºC for 2h in a

glow discharge environment. After plasma nitriding, the structural and mechanical properties of plates were characterized

by XRD, SEM and a micro-hardness tester. The static and fatigue properties of untreated and plasma nitrided plates were

determined by static and dynamic bending tests according to ASTM F382—17 (Standard Specification and Test Method

for Metallic Bone Plates). The structural examinations showed that a compound layer consisting of TiN and a diffusion

zone formed after plasma nitriding and thicknesses of TiN layer and diffusion zone were about 1.5-3 µm and 60-70 µm,

respectively. The static test results revealed that the static bending properties of the bone plate showed a little increase.

However, fatigue life of plasma nitrided bone plate exhibited approximately 30% improvement in comparison to untreated

plate.

ABSTRACT

It is possible to make an artificially lipid membrane by the planar lipid bilayer method. This method is used in some

biological applications to provide single channel analysis, opening and closing dynamics of channel proteins. Here the

artificial lipid bilayer is constructed over a micron aperture and generally, micropores are generated on a thin film-

shaped teflon films, treated by certain chemicals. Teflon (PTFE, Polytetrafluoroethylene) provides high stability for the

lipid layer for long periods of time because of its chemical stability while providing low-noise recordings during the

experiments due to its high resistivity1. One of the methods to generate a micropore on a Teflon film is to expose the

film to an high energy discharge or ‘burn’ its surface created by a transformer2. In the light of this information, a

microprocessor, computer and a transformer were used to produce a cheap way device. In the Teflon burning via high

voltage process, it was aimed to make a pore in the range of 50-100 microns of size as shown in Figure 1.

HOW INDUSTRY 4.0 IMPACTS IN PHARMACEUTICAL INDUSTRY

ABSTRACT

Global businesses are about to integrate their operations into a seamless digital whole, aiming to incorporate flexibility,

agility, re-configurability, and sustainability to the supply chain organization. Industry 4.0 represents the fourth industrial

revolution that transforms manufacturing by using state-of-the-art technologies including automation, data exchanges,

cloud computing, intelligent robots, Big Data, and Artificial Intelligent, the aim is to achieve ‘Smart Factories’. A smart

factory brig two currently disconnected environments i.e. Information Technology (IT) and Operational Technology (OT)

(digital and physical environments) using an approach called as “Cyber-Physical Systems”. A cyber-physical system

(CPS) is a system of collaborating computational elements to control physical entities. It is physical and engineered

systems, whose operations are monitored, coordinated, controlled and integrated by a computing and communication

core. CPS allows systems to boost computational capabilities by integrating computational and communication

technologies with physical objects.

The use of Industry 4.0 and smart-factories have been primarily investigated in manufacturing of electro-mechanical

systems. More and more manufacturing enterprises in those domains are trying to shift their industry to the smart factory

level since has the potential to reduce costs and, improve flexibility, productivity and sustainability of the manufacturing

system. Electro-mechanical manufacturing industries have major differences than the pharmaceutical industry as their

system is usually more flexible and, the regulations on their manufacturing processes and end products are far less tight

than pharmaceutical industry. Until recent advances in Process Analytic Technology (PAT), Quality by Design (QbD)

and Continuous Manufacturing (CM), the pharmaceutical industry had been slow in adopting innovative manufacturing

technologies. This is partly due to critical risks involved with pharmaceuticals, and tight regulations imposed by regulating

organizations to control these risks. However, the rate of adoption of new tools has been increasing in pharmaceutical

industry due to tools introduced by regulating organizations. The advent of the PAT and QBD tools created a suitable

environment for adopting new approaches in pharmaceutical manufacturing. The Industry 4.0 and smart factory

approaches offer further advantages to improve the quality and reliability of pharmaceutical manufacturing. However, the

practical application areas and potential benefits of these tools not been examined thoroughly for pharmaceutical industry

in the academic literature, and these tools should be carefully modified and adapted to be integrated with the exist tools.

A few brief reports about smart pharmaceutical factories are available from commercial companies, but most of them

describes the equipment and infrastructure that could be used for in pharmaceutical manufacturing, rather than its actual

use, benefits and pitfalls. There are valid reasons and perhaps requirement for pharmaceutical industries to embrace smart

factory and to ‘‘borrow’’ the concept of Industry 4.0 to give rise to ‘‘Pharma 4.0’’, i.e. the pharmaceutical version of

industry 4.0. The aim of this paper is to propose a framework for Pharma4.0 which holds the modifies and adapted version

of the smart factory tools and approaches aiming to employ them along with regulating organization’s
