FOREWORD

The Faculty of Electrical Engineering and Computer Science is organised into eight institutes: Institute for automatics, Institute for computer science, Institute for electronic and telecommunications, Institute for informatics, Institute for mathematics and physics, Institute for media communications, Institute for power electronics, and the Institute for robotics. These Institutes consist of laboratories, which are specialised for specific research areas. Beside research, the institutes also take care of pedagogical work at professional, university and postgraduate levels. In this way, scientific and research work are neatly connected with pedagogical work. The students of higher classes are frequently included in research projects of the laboratories. In this way, they refresh their theoretical knowledge, they obtain experience and strengthen their engineering enthusiasm, which is extremely important for a creative and successful career. This is the reason why our graduates are respected and sought after within the industry.

In 2007, we started to educate students according to the Bologna initiative. We hope that this generation of students will achieve a higher-level of knowledge. The students will soon be included in research work to obtain the required engineering expertise. We will support their creativity and self-initiative.

Despite some periodical financial difficulties, this report demonstrates that our faculty is involved in research and scientific projects at home and abroad. Our achievements are regularly presented at different scientific conferences and in those scientific journals with high reputations. The Faculty's management will support all the prosperous groups, laboratories and individuals by introducing a new, more flexible and stimulative organisational system.

Dean Prof. Dr. Igor Tičar

Graduate Studies

Graduate studies are basically aimed at the acquisition of in-depth theoretical and applied knowledge, enabling the prospective graduate to carry out independent and creative research in various technical sciences.

Masters degree and PhD studies

In 2007, Masters degree and Doctoral studies were organised, as shown in the preceding diagrams, in combination with the undergraduate schemes. It was then enhanced with additional subjects. All the subjects were also grouped into two subsets: the smaller one contains majors according to different study options, while the larger group comprises choices. Every student must select at least two majors belonging to his or her study option.

Three graduate programmes are currently being offered:

Electrical Engineering

Electronic Vacuum Technology

Computer and Information Science

Their supervisor selects the following for every graduate student entering the first year of studies:

• the courses that the student will attend and the exams the student will complete • a research project that will be individually assigned to and conducted by the student

The student must collect a minimum of 120 credits during the first two years. Out of this total, 75 credits must be awarded for the examinations, while 45 credits must be awarded for the reports completed on their individual research projects. The student is awarded 15 credits for every passed exam and publicly presented report on individual research projects.

Terms for Progress

The terms of reference for the postgraduate studies are specified by the Statute of the University of Maribor and by annual public scrutiny. Other student obligations are depicted by labels through in the graphical presentation of academic-degree studies.

Minimum of 30 credits.

The student must pass all the exams during the first two years and present the reports on their individual research work with a minimum average grade of 9 (out of 10).


According to the Regulation of Habilitation Procedure for University Teachers, Scientific Workers and Co-workers valid at the Faculty of Electrical Engineering and Computer Science, the student's bibliography must be awarded a minimum of 2 points, based on their scientific research activities. Additionally, a recommendation letter from the student's doctoral studies supervisor is requested.

According to the Regulation of Habilitation Procedure for University Teachers, Scientific Workers and Co-workers valid at the Faculty of Electrical Engineering and Computer Science, the student's bibliography must be awarded a minimum of 2 points, based on their scientific research activities.

During the third year of study, students must report twice on their research work, and once during the fourth year. This totals to 45 credits. Additionally 75 credits must be awarded for a successful presentation and defence of doctoral dissertation. According to the Regulation of Habilitation Procedure for University Teachers, Scientific Workers and Co-workers valid at the Faculty of Electrical Engineering and Computer Science, the student's bibliography must be awarded a minimum of 5 points, based on their scientific research activities. At least 1 point must be awarded for publishing research findings in the journals cited in the INSPEC database.

Masters degree studies are research-oriented and include an introduction to research, the development of students’ capacities for research work in individual scientific fields and disciplines, and the study of subjects providing the in-depth and broad knowledge of subjects needed for the preparation of a Masters thesis.

Throughout the programme of study, graduate students can use laboratories and the computer infrastructure of the Faculty of Electrical Engineering and Computer Science, as well as those of other engineering faculties at the university. Studies leading to Masters degrees grant the graduates a professional title of Master of Science in Electrical Engineering or Master of Science in Computer Science.

PhD research is carried out in research laboratories; a more detailed description of these programmes is given in the continuation of this report. Research teams consisting of doctoral students and graduate students for individual areas of research are commonly formed. Some research teams include participants from several laboratories. International contacts developed through the teams are especially important for doctoral students, because this is the only way for them to take part in the international transfer of knowledge and exchange research achievements. Some of our doctoral students carry-out part of their research abroad and even have co-mentors in other countries.

We believe that creativity, openness, peer support, and reciprocity are the bedrock of any academic co-operation. Therefore, the Faculty of Electrical Engineering and Computer Science regularly hosts foreign undergraduate, graduate, and postdoctoral students. Our new organisation


of doctoral studies also leads to a greater compatibility with other universities, making it easier for student exchange and mobility.

PROGRAMME UNITS

Seven programme units exist at the Faculty of Electrical Engineering and Computer Science, which are registered with the Slovene Research Agency. The work in these programme units represents the basics of fundamental research at our faculty, as they include the majority of our researchers. The quality of programme units is examined every year. A condensed overview for 2007 is collated in the sequel.

1. Telematic

Programme unit head: Prof. Dr. Žarko Čučej

This programme unit consists of the staff of the Signal Processing and Remote Control Laboratory, Systems and Control Laboratory and Digital and Information Systems Laboratory.

Scientific disciplines: Computer Science, Informatics, Metrology, Systems, Telecommunication Engineering.

Telematics -- synergy of telecommunication and information -- is a foundation of modern information society. It enables services, which are changing the paradigm of personal life, industry and connection to the world. Our activities in recent year have focused on two area, signal processing remote sensing application, and wireless sensors network. In the first area we have developed a novel algorithm for de-noising SAR images. This algorithm is based on Bayes method in the wavelet domain. In the second area we have developed new models for the calculation of signal propagation which enable better characterisation of transmission channels in personal area networks used for medical data telemetry.

2. Control of electromechanical systems

Programme unit head: Prof. Dr. Drago Dolinar

This programme unit consists of the staff of the Electromechanical Systems Control Laboratory and Power Engineering Laboratory.

Scientific disciplines: Automation, Electrical Engineering, Electromagnetism, Mathematical and General Theoretical Physics.

The research programme "Control of Electromechanical Systems" consists of different areas, such as design of electric devices, control design of electromechanical systems, and system researches of electric power system. Balanced representation of all discussed scientific areas can be seen from previous annual reports, as well as from the contents overview of published scientific papers. The research subjects are closely incorporated into the domestic industry and social infrastructure, which both of can see their perspective in the development of highly technological electric devices and undisturbed power system operation with an optimal exploitation of energy sources. The growing amount of industrial projects managed by our researchers implies that certain tasks in the


industry can be realized more efficiently with our knowledge. All areas are combined into one unit by applied dynamic treatment, which represents the basis for control design in the broadest sense. Within the framework of the first area, the research team analyzed various approaches to the dynamic modelling of electromagnetic devices and complex technical systems (analytical models). A new concept for IM torque control was developed based on its non-holonomic structure. The proposed torque control assures high dynamic in torque response, asymptotic stability and maximal efficiency under all feasible operational conditions. The new part of the research was the design of an improved spot-welding system operation by considering the magnetic nonlinearities of an output transformer for the Indramat d.o.o. company. Within the framework of the second area, the research team continued the dynamic modelling and analysis of a power system's elements and the power system as a whole. Again, the dynamic approach was used. Part of the project related to the detection, location and classification of faults in the distribution networks. Several methods for fast and accurate estimation of loop-parameters were derived. In contrast to methods that are based on signal approximation with a series of orthogonal base functions, the proposed methods are much less-sensitive with respect to the DC component, higher-, sub- and inter-harmonics, as well as with respect to the measurement noise in the voltage and current signals. Developed methods that are verified with simulations are based on deterministic and stochastic line models in differential and integral time discrete forms.

3. Mechatronics systems

Programme unit head: Prof. Dr. Karel Jezernik

This programme unit consists of the staff of the Industrial Robotics Laboratory, Power Electronics Laboratory, Electro-Optics and Sensor Systems Laboratory, Measurements Laboratory and Process Automation Laboratory.

Scientific disciplines: Automation, Intelligent Systems, Motors and Propulsion Systems, Robotics, Systems.

Mechatronics and robotics are topical scientific and industrial activities in most developed states worldwide. The development of mechatronics systems presents a guarantee of development, technological progress and, thus, overall societal progress in both developed and underdeveloped countries. The use of information and communication technologies represents a prime contribution to the development of new mechatronic products, an improved competitive position for national economies, and also to the reduction of energy consumption. All over the world enormous effort is being made in the fields of controlled drives, electronic voltage inverters, embedded systems, and telerobotic applications connected with virtual environments for technological solutions' demands, from macro- to nano- world. Likewise advance in the field of optical MEMS sensors and measurement instrumentation interferes with the most topical and promising fields of science, like nano-, optical and sensor technologies and their combinations, and takes care of the transfer of these technologies into practical use. Observed from the viewpoint of Slovenia's technological progress, research in the field of mechatronic systems is of vital interest, as the development of state-of-the-art products cannot be


imagined without them. In order to assure their proper introduction into industrial practice, it is essential to support high-quality research centres, which have to serve as a support for the industry. Mechatronic systems present one of the most important exported groups of articles from Slovenia (Domel, Iskra Rotomatika, Iskra Mehanizmi, Kolektor, Motoman Robotec, Iskra Avtoelektrika, IPS Ljubljana,…). However, most of these products are of a low technological level, which is reflected in the low added-value. Thus, over the last few years, they have had to be upgraded or replaced with more advanced ones. In order to be able to reach a higher living standard, the technological direction of our industry will have to change, and the results of project teams' research will play an important part. Projects ensure companies have access to the knowledge and tools required for their progress. Thus, it influences their technological advance and enables growth in the number of innovations, which results in a growing added-value of products. The project team contributes to a growing level of knowledge in the areas it covers. All of the research topics of our programme group are of exceptional importance for the global progress of science, which can be shown by the greater number of publications in relevant international literature. The use of mechatronic approaches presents an important stimulation in the growth in the number of innovations, and the introduction of many new products, which can also represent novelties in the global market. Thus, Slovenia is receiving the opportunity to take its place among the most advanced countries of the world in a relatively short time. Research in the fields of controlled drives, electronic voltage inverters and embedded systems presents an important contribution towards the improved competitive positions of our companies. The improved quality of control also means a reduced use of energy, which results in reduced pollution of the environment and, thus, the preservation of natural and cultural heritage. Electromechanical drives belong among the most important consumers of energy and already a small improvement in their efficiency has resulted in a notable reduction in energy consumption on a national scale. The programme in the field of optical MEMS sensors and measurement instrumentation reaches into the most important and interesting areas of science, such as nano, optical and sensoric technologies, together with their combinations, transferring technologies into practical use. The results of research in the field of fiber-optic mode filters will enable singlemode connections with the use of fibres, which would enable multimode operation. In the area of fibre-optic sensors the main issue of our research is FP interferometers and low-cost sensors on the basis of plastic fibres. We successfully produce various prototypes of sensors. Studies into the possibilities of modified modulation techniques, where the modulation signals are deliberately contaminated by noise, microcomputer units and inverters of all kinds, represent a global contribution to this progress. Microcomputers are currently not applied in DC-DC converters at the local level. Complex control algorithms, where we have to deal with nonlinear control objects, are executed in special integrated circuits. Their replacement with the standardized microcomputer units will accelerate progress in this field. Efficient use of energy is gaining significance. In this area the activities of the research group are directed towards the development of components and procedures for efficient energy transfer and conversion, more specifically into the development of converters for renewable energy sources, and the implementation of digital algorithms for the control of simple DC-DC converters. For this


purpose, a required infrastructure has been built, consisting of electronic components and corresponding software for the implementation of non-linear control algorithms on FPGA circuits. This field of research was then extended to the use of alternative energy sources. An experimental system with the PEM fuel cell was built for this purpose. It includes a 1.2 kW Ballard NEXA fuel cell with the corresponding control and supervision system, connected to a hydrogen reservoir. Activities in this area are focused on the development of suitable converter structures, which will enable a continuous power supply for the optional AC or DC loads. Converters will be connected to the system, where all energy flows will be controlled. This research represents a contribution to the development strategies of Slovenian companies, which is directed towards positioning themselves on international markets as the provider of advanced high-tech solutions for mobile electrical propulsion systems and actuators using fuel cells, but also other energy sources. Research in the field of control drives presents one of the most important research topics in the whole technical domain. The importance of this topic is further increased due to the global trend of replacing hydraulic and pneumatic actuators with electromagnetic ones, which are not only easier to control, but also cheaper and consume less energy. The improved quality and reliability of electromechanical actuators’ control also represents progress in many areas where they are used as drives. Better control (constant torque, less vibrations, improved dynamics …) enables the production of improved systems. In the field of AC drives’ control without the use of speed and position sensors, current research into very low speed, field weakening, regenerative and optimal operations represents a most important topic. The importance of this area is represented by the large number of research groups in the best universities and institutes worldwide, dealing with problematics. Research into the control of electrical drives is focused on applications in the automotive industry, where the reliable and energy-efficient operation of drives is a key issue. Research efforts in the area of event systems are connected with a variety of technological fields, however, a significant contribution relates to the development of new production technologies. Rapid and efficient response to the changing demands of the markets can be assured with the introduction of advanced production procedures such as "product on demand" and "customized products". This can only be achieved with flexible and reconfigurable production, which enables simple and cheap changing of existing, and the introduction of new products. Contemporary automatization approaches have to combine the adaptability of low-series production technologies with the efficiency of high-series production lines, which cannot be imagined without the use of mechatronic systems. Over the last decade, systems of automation, control and supervision, based on PC architecture, have become state-of-the-art, especially in the field of SCADA systems. On the other hand, closed and hardware based solutions are still dominating the field of CNC systems, although open solutions using the PC are emerging. The prime interest of research into these technologies is the introduction of open standards for embedded and specialized systems of distributed hardware and software. This is due to the fact that they enable upgrading, extension and interoperability. Additionally, open architecture shortens the design cycles, increases productivity, and reduces production times interruptions, and the cost of maintenance. Research in the field of advanced control of systems is focused on the development of modern algorithms for the real-time control of non-linear systems. Possibilities for application of different control methods for non-linear processes, where some of the process states are not measurable,


are under investigation. Non-linear reduced and full order observers are applied for this purpose. In the field of error recognition, isolation and diagnostics mathematical-statistical methods are introduced for the on-line operation. New approaches are applied in the area of modelling hydraulic processes, based on models of industrial hydraulic components (regulation valve, vessel, pump, pipeline). Models are designed for the simulation, testing and synthesis of control algorithms, detection and supression of faults, as well as supervision and similar applications. In the field of embedded systems in welding technology, the possibilities of on-line quality-control during the operation are investigated. Teleoperating, and especially its branch telerobotics, is a new and rapidly developing interdisciplinary domain of robotics, remote-control, virtual-reality, and human-machine communications. Many important laboratories worldwide put a lot of effort into the development of experimental teleoperation using intelligent virtual-interface, especially for applications in macro (telerobotic hands for the execution of remote medical operations), micro (robots for moving objects smaller than 1 mm), and nano (robots for cutting molecules) worlds. Research in the field of teleoperation is focused on the execution of a remote-control robotic arm and mobile robot, where unpredictable delays of data transfer through the Internet have to be taken into account, which is a current topic of research worldwide. For the purposes of remote measurement monitoring, data acquisition drivers and user interfaces are being developed using LabVIEW software. The LabVIEW application enables monitoring of the measurements and modification of those parameters needed for the testing of various elements and instruments under different conditions. The measurement monitoring and parameter changes are performed remotely via the Internet. Server application sends the table of active cameras with corresponding URLs (Uniform Resource Locator) and experiment titles to the client application. Camera list and JPEG-compressed image data are sent over the Internet by using LabVIEW shared variable. Research into noise pollution in various environments such as workplace and residential environments or environments with high-intensity machine-created sounds is carried out. An overview of noise pollution standards was carried-out and theoretical background was researched. In addition, experimental measurements were performed. Comprehensive research is conducted into the potential hazards of radio communication devices non-ionizing radiation. A benchmark study was carried out between the EU and NATO. Both urban and rural areas was included in the research. Its results are used by rescue teams and people working or living near such devices. Research in the area of kinematics and simulations is conducted in the direction of formally describing gyroscopic devices' operations, modelling techniques with simulation results with the illustration and presentation of experimental results, followed by their evaluation. In this work, cooperation takes place with the Institute of mathematics and physics at our faculty. The main contribution is the development of a dynamic model, describing the operation of the device covering all three possible operations: free flywheel and both cases of the rolling connection between the flywheel axes and device casing. Robotic control is also investigated, restricted to the heuristic approach and use of a torque sensor on the single degree of freedom.


4. Advanced methods of interaction in telecommunication

Programme unit head: Prof. Dr. Zdravko Kačič

This programme unit consists of the staff of the Microcomputer Systems Laboratory, Digital Signal Processing Laboratory, Electronic Systems Laboratory and Digital and Information Systems Laboratory.

Scientific disciplines: Signal Processing, Telecommunication Engineering.

In 2007 research work was carried out in two main research areas. The first one encompassed advanced multimodal communications, where the following developments were carried-out: large vocabulary speech recognition, language modelling, fast search algorithms for continuous speech recognition, speech-to-speech translation, and image segmentation. The goals of the research in the area of system-correctness assurance was the development of new methods for formal or semiformal specification and verification of contemporary reactive systems. In the field of digital speech processing, pitch-period and pitch frequency estimation algorithms have been enhanced. The pitch-period, as well as fundamental speech frequency, are important parameters in modern text-to-speech synthesis algorithms, as well as in other pitch-synchronous speech signal analysis procedures. In the field of acoustic modelling, an “on-line” and “off-line” speech synchronisation system used for animation of avatar Maja was developed. The baseline Slovenian Broadcast News continuous speech recognition system was enhanced. Acoustic models for the Babilon speech-to-speech translation system were also upgraded. In continuous speech recognition, the work was primarily oriented towards the enhancement of search algorithms. The recognition accuracy of the large vocabulary continuous speech recognition system of Slovenian language was evaluated on the Slovenian Broadcast News BNSI speech database, and was further increased. Language modelling focused on broadcast news and parliamentary speech domains. The language models with vocabularies of 20k and 60k words were further enhanced and are ready for integration into the large vocabulary continuous Slovenian speech recognition system. In the year 2007, basic research activities for developing speech-to-speech translation components continued, and the target application of communication scenario of orentation in urban forreign environment was accomplished. Within the framework of the programmed part of system correctness assurance, in 2007 we continued with the development of our tool for automatic verification of reactive systems EST (Efficient Symbolic Tools). We started to develop, implement, and test algorithms for the so-called “on-the-fly” model checking for formulae of the ACTLW logic. They were shown as more efficient than the currently supported global model checking, at least for some kinds of systems. We developed approaches for the formal specification and verification of systems based on the input-output automaton mathematical model by using languages, TLA and TLA+. We began to study appropriateness of MTLA for the specification of systems, using dynamic process creation.


5. Information systems

Programme unit head: Prof. Dr. Ivan Rozman

This programme unit consists of the staff of the Information Systems Laboratory, Database Technologies Laboratory, Computer Mediated Communication Laboratory and Real-Time Systems Laboratory.

Scientific disciplines: Business Process Reengineering, Communication Methods, Computer Science, Databases, Development Methodologies, E-business, Informatics, Information System Development, Intelligent Systems, Operations Research, Quality Assurance Systems, Real-Time Systems.

The focus of the research group is on the holistic development of information systems (IS). It addresses several inter-connected areas: methodological aspects of IS, databases and data warehouses development; quality assurance strategies; information technology support for inter-organisational business operations; design and construction of embedded systems; reliability assurance and security of embedded systems; evaluation and improvement of process and architecture models; IS integration methods; use of intelligent systems, agents and automatic programming techniques for the IS reliability improvement; security aspects of IS development; data and databases' security; efficiency of classification algorithms for the construction of data warehouses, and integration initiation for information quality improvement. Methodological aspects of IS development address the development and definition of new, more effective techniques, methods and methodologies of business process-modelling, requirements analysis, and the architectural design, implementation, verification and validation of IS and IT management. The emphasis is on the object- and component-oriented approach, and on services-based architecture with semantic component and context- and aspect-dependent behaviour. One of the key issue is the assurance of information services' integration, which address also the next key issue of efficiency improvement: re-use, for which formalization on a higher level of abstraction (ideas, patterns, frameworks, components and heuristics) is done by introducing various repositories, identification, and application mechanisms. Methodological research offers a sound base for those methods and mechanism definitions supporting information technology in inter-organisational business operations, primarily between businesses, but also for customers and employees. The main goal is the construction of inter-organisational integration based on the existing standards of web services and the enhancement of web services by a semantic component. The final goal is the automatisation of all levels: definition of business processes, definition of cooperation profiles, electronic contracts definition, and business operations execution. The security aspects are oriented towards quality assurance of IS development and assurance of data quality. The research group traditionally dedicates much attention to quality and continues with the research on defining new approaches for introducing quality management systems in IT sectors and on defining formal methods for software processes' modelling. The focus is also on the quantitative evaluation of software processes, products, and data quality. The development of


distributed service-oriented architectures is addressed from the perspective of model-driven development, cross-platform integration, and performance evaluation. Within the scope of research relating to databases, data warehouses and data-mining, preference is given to information production processes and their improvement by considering structured data development and analysis procedures at the enterprise level. Within the scope of knowledge-based systems, our research focuses on the development of models for effective project management, definition and evaluation of methods based on fuzzy logic, intelligent agents, operations research, and artificial intelligence.

6. Applied Electromagnetics

Programme unit head: Prof. Dr. Mladen Trlep

This programme unit consists of the staff of the Fundamentals and Theory of Electrotechnics Laboratory, Applied Electromagnetics Laboratory and Electrical Machines Laboratory.

Scientific disciplines: Electrical Engineering, Electromagnetism.

The research programme “Applied Electromagnetics” is composed within three areas, which are interactively connected and all three lean towards a unified theoretical origin, which is based on the macroscopic theory of the electromagnetic field, mathematically determined by Maxwell’s equations. Because of their specifics, these areas are treated parallel within the framework of the programme, but the final aim is to combine all of this knowledge into a comprehensive system, which will cover, as much as possible, all the demands of real direct or inverse electromagnetic problems. The first part focuses on the research and development of real mathematical models for the determination of magnetic, electrical and heat fields according to the conditions of the stationary and dynamic working conditions of electric, electromagnetic or electro mechanic systems or devices. For the mathematical solving of these very complex problems ,we choose a finite element method and a boundary element method. In the year 2007 we intensively researched the field of electrical machines. For the electronically-commutated motor with permanent magnets different possibilities for the reduction of the undesirable oscillations of the rotational torque were studied, with the emphasis on the analysing the engine's geometry and method of engine supply, with the inclusion of a created 3D transient numerical model. In addition the study and development of a magnetic twin-axis model of a synchronous motor with permanent magnets with outside rotor and research work into a Flux-reversal (FR) electrical engine with permanent magnetis were carried-out. The influence of an electromagnetic field on the environment, particularly its influence on people and on a different electrical devices is becoming a more and more important research area. Last year we developed a model, which considers the influence of objects in the surroundings of long-distance transmission lines, on the distribution of an electromagnetic field. This step is very important for developing a complete model, because in this way we can come nearer to the real conditions, because only real conditions make it possible to actually estimate the field's influence on its surroundings.


Knowledge of the real materials' properties is very important for solving field problems using numerical methods. The development of measuring methods points towards measuring methods for accurately determining real materials' characteristics, and accurately determining losses in the materials, which is needed for an »as near as possible« complete mathematical model of the electromagnetic system. Over the last year we investigated in a rotational single sheet tester, the interaction of the magnetic field between lamellas of high-orientation and between lamellas of the classic-oriented sheet. The third part of the research programme focuses on the development of the models which are useful by the solving of inverse problems in electrotechnics. Last year we continued with the development of an experimental 3D model, which will make possible the evaluation of an inverse-problem developed numerical model, and the evaluation of its programme solution quality.

7. Computer systems, methodologies and intelligent services

Programme unit head: Prof. Dr. Damjan Zazula

This programme unit consists of the staff of the Computer Architecture and Languages Laboratory, System Software Laboratory, Heterogeneous Computer Systems Laboratory, Geometric Modelling and Multimedia Algorithms Laboratory and Computer Graphics, Artificial Intelligence Laboratory and Programming methodology laboratory.

Scientific disciplines: Artificial Intelligence, Bioinformatics, Biomathematics, Computer Graphics, Computer Science, Computer-Assisted Education, Distributed Computing, Geometrical Modelling, Image Processing, Intelligent Systems, Internet Programming and Web Services, Medical Informatics, Multimedia, Programming Languages and Computer Architectures, Signal Processing, System Information Theory, Systems Engineering, Systems Engineering and Computer Technology.

In 2007, we developed the object-oriented programming language Zero. This language is statically-typed and capable of structural and behavioural run-time reflection. Metaprogramming is realised by means of metaclasses which enable introspection and changing of properties during execution. The language exhibits a uniform object model, where even the methods are represented as objects. This allows anonymous methods, higher-order methods, and run-time method specialisation. In the field of evolutionary algorithms, we developed a self-adaptive differential evolution algorithm, called DEMOwSA, for multi-objective optimization. The idea of differential evolution was also applied in constrained real-parameter optimization and in searching of parameter values for evaluation function of our chess program. Within the field of artificial life, we developed algorithms for the interactive breeding of artificial ecosystems. In 2007, we continued developing a spontaneous afforestation simulator, based on Ellenberg ecological factors. Algorithms for the level of detail were added to enable faster visualization of trees, which appear in large numbers and demand a lot of computer power to generate them. In this way, the walk through the virtual-countryside was significantly increased. We also added


those new tree species which also occur in our country, as well as in the whole region at our latitudes’. We also developed a novel application of fuzzy-genetic decision support to the problem of project-team formation. The required team capabilities are expressed using fuzzy descriptors and the task is formulated as a multi-criteria optimization problem. We proposed a special adaptation of an island genetic algorithm with mixed crossover, in order to optimize the selection of multiple project teams with possibly conflicting requirements. In collaboration with the Administration for Civil Protection and Disaster Relief we started developing an application to instruct those workers who deal with removing hazardous materials, by teaching them the correct procedures for handling accidents involving hazardous materials. This application is based on displaying the correct interferring procedures and testing the knowledge of participants. To achieve this, we had to develop 3D models of intervention workers, such as firefighters in various protective suits with or without self contained breathing apparatuses, policemen, rescuers and corresponding equipment used by them. The application enables the run of predefined scenarios, tests the response of participants and can be used for the instruction of both supervisors and direct intervention workers. In 2007, we deployed, in practice, several approaches we had researched in the field of signal and image processing during previous years. We developed a real-time version of a method for decomposing compound signals, which is based on convolution kernel compensation. This real-time version is going to be applied in a few up-coming research projects that involve the decomposition of surface electromyograms (sEMG). At the same time, we studied the sEMG signals from two additional viewpoints: we tested their suitability for modelling muscle contraction forces and for classification of neuromuscular diseases. A novel classification approach was developed based on multiscale entropy criterion. We also designed two devices for sEMG measurements: a multichannel sEMG measurement tool, which is still under construction, and a mechanical grip to support isometric muscle contractions and measurements. Our efforts were also directed towards new algorithms for the segmentation of 3D ultrasound volumes. In collaboration with the University Medical Centre of Maribor, we built a system for the computer-based detection of ovarian follicles. A special algorithm was developed for registering the detected follicles in 3D. Physicians can now follow the growth and changes of follicles and their surrounding tissues, e.g. perifollicular network of blood vessels. In 2007, joint research was conducted together with the Gorenje Velenje company on a multiagent simulator for household appliances. We established a new development centre by installing Gorenje connected appliances. This centre is located in our department in Maribor and will support research and software development for these types of devices. We are going to study any upgradings possible in the field of services for connecting devices, while, at the same time, additional functionality will be tested, such as supportive components for the elderly and intelligent home services. In the field of geometric modelling, we studied methods for modelling terrain regarding static and dynamic objects. Here we had to consider the concrete requirements of the end-user. We also continued the research of surface reconstruction from a point-cloud, lossless compression of


DICOM medical data, and compression of time-variant (4-D) voxel data. Within the area of geometric data compression, we dealt with chain-codes. Computational geometry algorithms we developed mostly solved problems relating to the requirements of customers (users of these algorithms in geographic information systems – GIS). We participated to the development of an open-source Geoserver, its configuration and use for displaying raster and vector data, with the help of an image mosaic. Furthermore, a graphical polygon editor, incorporated in the management software package for subsidies in agriculture, was extended with new functionalities. We also coped with corrections and simplifications of polygons obtained from GIS measurements, with visualisation of maps in different resolutions, and with determination of GPS locations in these maps. In addition, we dealt with the adaptation of an existing spatial data system GIS-UJME for wider use and to linking it with other information systems towards an integrated system of civil protection and disaster relief. We improved our sweep-line-based algorithm of constrained Delaunay triangulation and adapted its implementation to the requirements of a customer from the USA. In 2007, we concluded our work on an R & D project that integrated the visual location of a caller in the GIS. This integration enables quicker response by intervention groups in those cases when the emergency phone number 112 is called. In addition, we also dealt with the problems of facility location, with polygon clipping algorithms, with approximations of free-form 3D geometric objects, with different data structures and algorithms for the nearest point problems, and with integrating these into our incremental Delaunay triangulation algorithm. Our research on domain-specific languages (DSLs) was intensified. We investigated several topics that are beyond the horizon of present knowledge: new DSLs' implementation approaches, DSLs development from APIs, grammar inference from DSL programs, metamodel inference from domain-specific modelling, design and implementation of domain-specific aspect languages, and the developing of language-based tools (e.g., debuggers, test engines) for DSLs. Research on DSLs was successfully applied in an industrial project for Hermes Softlab – a prototype of DSL for service level objectives manager. In the area of evolutionary computations we primarily investigated the parameter control of evolutionary algorithms, using entropy and self-adaptive local search. In 2007, our research focused on a QA system in which a user can submit questions in our native language (Slovene). We used information which is publically accessible through the faculty web-portal and through Web Services that provide information about the university’s personnel. For the system to function properly, we use a special morphological dictionary that contains over three hundred thousand basic word forms (lemmas) and over eight million possible word forms. We also built a special domain specific dictionary, partially with the help of experts and partially using an automated analyse of web documents. This domain-dictionary provides us with determined relationships between words (similar meaning, opposite meaning, abbreviations, etc.) in the appropriate hierarchical structure. Besides our reseach work, we are continually focusing on upgrading the Application for Computer-aided Control of Ecological farming (EKOFARM2), which was developed for the Ministry of Agriculture, Forestry and Food of the Republic of Slovenia. We also established a digital library for the University of Maribor and produced portals on our own CMS technology. Currently our digital


library contains over three thousand five hundred diploma works that will be used as input texts for research regarding classifications, knowledge extraction and the automatic creation of content for our question-answer system.

There is a significant lack of studies in e-learning at universities in Serbia. At the same time there is a growing need for e-learning, not only for higher education, but also at any level of education, within the program of life-long learning and, finally, for industrial and organizational purposes.

Therefore, it is major need for all Serbian partner universities to establish studies leading to a M.Sc. degree that will educate future experts for the design and implementation of e-learning. These experts will be highly specialized in the planning, budgeting, development, delivery, and support of e-education and distance training programs. In order to accomplish this, it will be necessary to create a number of new courses in the field of e-learning following the Bologna declaration, and to re-train teaching staff. The new M.Sc. curricula in e-learning must be in-line with those used at the world's leading universities in the relevant fields of study. The aim of the project is to create and implement a M.Sc. curriculum in e-learning according to the Bologna declaration, for all consortium partners from Serbia.

- Since the new law of higher education in Serbia anticipated e-learning, the need for qualified experts in this field is self-evident and, therefore, creating a M.Sc. curriculum in e-learning is esential. These experts will be required as active advocates of e-learning in their organizations and need to manage significant change-processes that affect the entire organization, and society as a whole.

- As a M.Sc. curriculum in e-learning doesn't exist at Serbian partner universities and e –education is one of the strategic goals in the development of information society in the Republic of Serbia, any new M.Sc. curriculum in this field will certainly be accredited by the Ministry of Education in Serbia. If the curriculum is accredited and supported by the Ministry of Education, its financial sustainability is ensured to some extent.

- A major goal of the "Strategy for the Development of Information Society in the Republic of Serbia" concerning the development of e-Education would be addressed by developing the new curriculum.

- Together with curriculum development, the purchasing of new equipment for supporting the


educational process would be enabled by the project's realisation.

- In order to solve problems identified by the e-Learning Task Force group, it is necessary to create qualified experts who will quickly introduce and implement the process of e-learning in Serbia.

- The implementation of this curriculum at partner universities will produce qualified experts in the field of e-learning and will provide an environment for teachers' and students' mobility.

- The project will also assure the retraining of partner universites teaching staff .

- These Master's studies should also be a good preparation for graduate students regarding Ph.D. studies in the field of e-learning.

Tempus: Practicum to Improve Ukrainian e-Learning System (PIUeLS)


Participants: Dr. Andreja Rojko, Asst. Prof. Dr. Martin Terbuc, Primož Kosec, Sinja Leskovec, Metka Zorič-Venuti, Živa Hohnjec, Prof. Dr. Riko Šafarič

Project partners: Kaunas University of Technology, Lithuania, Zaporizhia State Technical University, Sumy State University, Ministry of Education and Science of Ukraine, Fachhochschule Kärnten, National technical university "Kharkov Polytechnik Institute", University of Maribor, Odessa National Polytechnic University


The issues of developing e-Learning have been discussed by the academic community for more than one year. At present, this problem is switching from the discourse and theoretical searches of e-Learning development to its real implementation in the Ukraine. The question of whether e-Learning is happening is no longer an option. Throughout the whole world e-Learning has occupied its own niche within the educational sphere, and the actuality of this form of education is now obvious – e-Learning is called-on to play a vital role in the formation and evolution in the European Higher Education Area (bringing in-line objectives, standards, and models) in the context of the Bologna process. Nowadays, there is a question of transition from the trainees’ mobility to the concept of mobility regarding ideas, knowledge, and educational systems.

Ukraine’s State interest, reflected in the Law of Ukraine on “Higher Schools”, the Programme of Informatisation of Ukraine’s Education, the Concept of DE Development in Ukraine and other strategic documents, including the Ministry of Education and Science of Ukraine (MESU), facilitate the process of introducing information-integrated technologies covering the whole life-cycles of educational services and is a very important and necessary element in


the process of reforming the structure and content of higher education in Ukraine. Namely on the basis of intensively introducing innovative means of e-Learning, a competitive market regarding educational services is forming, and universities are the chain in this process.

This project is devoted to the development of e-Learning within the UA system of higher education through improving university e-Learning systems. The actuality of problems for improving e-Learning systems in partner universities is well-grounded, since the situation nowadays is that UA universities have definite developments in the area of applying e-Learning technologies in the training process (availability of technical base, DE centres, own virtual training environments, experience of working in e-Learning systems, and management of educational programmes), but cannot always use and develop e-Learning resources in their universities. This project is based on the fact that the participating universities understand and take into account the fact that the process of introducing e-Learning technologies at a HEI itself must be carried-out with the application of a programme-objective approach, since it requires solving a set of tasks connected with creating organisational, staff, financial, methodical, programme, technical and other types of provisions. However, before applying such an approach for improving a university's e-Learning system to its full extent, university staff must direct their efforts towards revealing (every UA partner HEI will carry-out a SWOT-analysis of e-Learning resources condition and define priorities) and targetting the solving of problems connected with the wide-usage of e-Learning technologies in the training process by means of raising the professional competences of administrators, managers and teachers, working under conditions of open-educational technologies.

The experience of EU partners in methodology and methods of creating e-Learning systems, as well as the application of methods for effective management in this field, would be extremely useful for UA universities. The method of its chosen transition within the project - holding a series of practicums in the area of improving e-Learning system – is the most effective one, since it will allow the partner HEIs to direct their efforts towards solving specific problems in the area of improving e-Learning systems in their universities. This is, initially, one of the ways of extending and raising the quality of e-Learning.

The main distinctive feature of our project is that the purposeful training of administrators, managers and teachers from the UA universities participating in the project, will result in practical implementation of their local projects for improving university e-Learning systems. Thus, UA universities' staff members will be able, not only to create a real operating e-Learning system, but having advanced their professional competence, will be able to develop an optimum model of an e-Learning system which can then be offered to other UA HEIs for creating/improving their e-Learning systems. A package of recommendations on improving university e-Learning system will be elaborated on with the assistance of EU experts and MESU representatives and disseminated down to the national level. Taking into account that MESU strategy in the area of UA e-Learning is aimed at its development and rests, first of all, with the Ukrainian Research Academic Telecommunication Network “URAN”, the project partners strongly believe that their developments and achievements in this area, as well as dissemination of the best results under the project will help to develop an e-Learning system


at educational institutions of all levels, in all the regions of Ukraine. In this way, feedback between the universities and the MESU will be ensured, that will ensure a qualitative decision-making process, while working-out strategic documents in the field of development of e-Learning system in Ukraine.

101-ASO Technical and Social Challenges related to Collaborative E-learning in Central and South Eastern European Countries

One of the key issues in establishing and promoting an Information and Knowledge Society in the South-East European countries (SEE) is the question of Information and Communication Technology (ICT) literacy among the citizens of these countries. As current research studies show, the level of this literacy in these countries is still very low and unsatisfactory.

There are numerous reasons for this disappointing situation such as deficiencies in the educational system (e.g. non-existent equipment, educational labour shortages), or slow-growing economies that do not allow improvements in the educational system.

One of the possibilities for remedying these issues is to establish a network-based educational platform that is accessible to a wide-base of citizens of the Western Balkans regardless of their age, gender, prior ICT knowledge, literacy level, nationality, or social status. Such an educational platform would serve as a media and content-delivery platform for educational content on ICT. However, this educational purpose can only be seen as a kick-start for wider social, network, and community purposes. As experiences from other developing countries show [Hassebroek 2001, Marquez 2006, Rahal 2004] network educational platforms that includ community aspects attract a larger number of users, initiate discussion and collaboration, causing network effect and, in turn, resulte in an improved increase in ICT literacy.

E-Learning can play a crucial role in establishing such a platform. Experiences, know-how, strategies, methods applied in E-Learning in the EU countries might be very helpful in the Western Balkan countries. However, the strategies of transferring this knowledge into another cultural and multi-facebed national context needs to be carefully considered and developed. The development of such strategies is indeed the main issue that this project will concentrate on. To test the development strategies in practice, one promising E-Learning product from an SEE country [Janicic 2006] will be considered as a case study and used to test parts of the strategies in advance.


BC EQUAL project: EQUAL STUDY

Leader: Jana Macarol (Univerza v Ljubljani) Participants: Primož Kosec, Živa Hohnjec, Matjaž Debevc

Equal study partnership has three main goals:

a) Goal – to establish better conditions in education for the disabled and through these better conditions for entering the labour market

b) Goal – to raise the educational levels of the young disabled population

c) Goal – to lower the level of unemployment among the disabled population.

Between measures for reducing structural disparity in the field of unemployment, the National programme for the development of the labour market also quotes the establishment of quality education for disabled students, which will lead to a reduction in school dropouts from university programmes. Social integration of marginal groups into the educational process and labour market is also very important. We intend to reach this goal through the establishment of adjusted study conditions and an establishment assistance department for students with special needs. In this contest we will develop multimedia support for lectures, mentoring network, career and study counselling, SOS telephone, and the drafting of an (international) employment network. These solutions would enable better conditions in education for the disabled and, consequently, better conditions for entering the labour market for all who have problems entering and re-entering it.

SOCRATES ERASMUS Project MARE – Joint European Master Degree Programme »Remote Engineering«

Leader: Michael Auer (Carinthia Tech Institute) Participants: Živa Hohnjec, Rajko Svečko, Andrej Knuplež, Matjaž Debevc, Prof.

Dr. Riko Šafarič

Financed by: European Union

The main task of the project MARE is to elaborate a complete new joint-curriculum in the field of »Remote Engineering«. The program is planned as a joint Masters degree programme.

The use of virtual and remote-laboratories and workplaces is one of the future directions for advanced teleworking / e-working environments especially in engineering and science but also in all other areas of society. This would also provide benefit for people with special needs and people working from home.

All over the world there is a lack of specialists in this field, and the number of needed specialist will increase dramatically over future years.


The general objective of the curriculum is to mediate fundamentals, applications and experiences in the field of remote-engineering by an interdisciplinary approach in combination with »learning by doing« phases. In this way we can create, in Europe, a unique possibility for studying »Remote Engineering«.

Technology-enhanced learning in a dual mode will be the central didactic approach.

The study programme is open for students from all-over and outside Europe and requires a Bachelor degree in engineering or in the science of informatics.

Graduates will be able to work in remote working environments and to develop such environments.

This project represents an important contribution to information Society Policies (Lisbon Agenda) and eEurope Action.

Interactive web pages with hyper-video on demand in the area of e-education


Participants: Dr. Dean Korošec, Primož Kosec, Samra Mujačić, Tanja Kocjan-Stjepanović

E-learning is gaining popularity and Bosnia and Herzegovina is aware of that, but still doesn't have a common development strategy, and e-learning is developing only partially, and independently. For this reason, an initiative from the University of Tuzla for developing joint e-learning material was very welcome. The university of Tuzla has already created an e-learning centre.

Recently visible solutions have arizen for the realization of laboratory exercises over distance, in real-time and with video control. Hyper-video as an additional connection form of media within video which is also becoming an attractive element of e-learning. In this project we will try to answer the following questions: duration length of the shot, quality of the shot, size of the shot, consumer satisfaction and others. Goals:

•Development of hyper-video learning materials for exercises in the area of digital systems and Human-computer interaction

•development of e-Learning lectures in the area of digital systems and Human-computer interaction

•education of pedagogical staff.

Implementation of a strategy for development and use of e-learning in Serbia and Montenegro


Participants: Primož Kosec

All around the world e-learning is gaining in popularity, and so it is in Serbia and Montenegro. It is evident that e-learning in Serbia and Montenegro doesn't have a common development strategy, and is developing only partially, and independently. For this reason, it would be very valuable to use results that Slovenian researchers have already acquired in e-learning strategy preparation, through various CRP projects, european projects and bilateral projects with Bosnia and Herzegovina, as a good starting point for the joint cooperation of slovenian researchers in developing an e-learning strategy for Serbia and Montenegro. Researchers and pedagogical staff from Serbia and Montenegro now need the professional support of slovenian researchers in order to prepare a solid base for e-learning strategy, instructions for creation of e-learning teaching materials and providing strategy for efficient training and education about e-learning.

The particular goal, based on the previous experience of european institutions and also the University of Maribor, would be the creation of a University e-learning centre. Its role would be providing pedagogical, technical, economical and legal support in developing e-learning. In this regard, UM FERI has experience from the creation of its Centre for distance education at the University of Maribor, altogether increasing the activities of the current centre, introducing new and state-of-the-art methods in supporting e-learning development. On the other hand, the Technical Faculty in Cacak has the necessary facilities and equipment for succesfull centre activities.

As the outcome of this project, innovative e-materials will be created that would commit to valid e-learning strandardization and would include directions for metadata usage according to IMS and SCORM specifications. Also, a special project goal would be to conceive and establish possible joint-research in the e-learning area and creates more possibilities for its application for european projects.

Project partners: City University, School of Engineering and Mathematical Sciences, Faculty of Electrical Engineering, Ss. Cyril and Methodius University


Duration: Oct. 2006 to Oct. 2007

Subject area: Education and teacher training.

The project focused on the problems and needs in higher education particularly shifting from professor-centered teaching to student-centered learning.

Main goal was the modernisation of the education system using new teaching methods. These methods are:

• engage and challenge students with the subject during class and drive them do develop explanations and discuss issues together;

• cause students to integrate the materials into their experience;

• engage students in such a way that the energy for learning also emanates from the students themselves.

All these methods can be achieved with computer-supported collaborative learning. The


benefit of multimedia in the computer-based collaborative learning project is two-fold: Not only does it help students learn their subject matter better, but it also helps them develop IT skills.

Project objectives:

1) To establish a multimedia-based teaching environment (equipped multimedia classroom and retrained academic staff to use it)

2) To introduce the collaborative learning approach at UKIM and to develop and deliver DSP courses

3) To motivate other professors to change their traditional teaching methodology.

101-INTERREG III INNOVIN

Participants: Matjaž Debevc

Duration: Jan. 2005 to Dec. 2007

The INNOVIN project was aimed towards an improvement and growth of the level of entrepreneurial culture, and the improvement of expert knowledge in the field of business within the academic environment, as well as towards increasing the number of spin-off and innovative enterprises within the cross-border region. It binds the following cities: Graz, Villach, and Maribor as important economic centres and the headquarters of university institutions. Within the framework of the project, establishing and improving the working of spin-off and innovative enterprises within the cross-border region were stimulated with the help of events, services, and the promotion of business within the academic environment, as well as by cooperation with local supportive institutions. Besides this, the project included the development and creation of interactive applications for education, mentoring, and market-specific information for the needs of spin-off enterprises. It also attended to building a cross-border network and data base for the needs of future founders of those spin-off enterprises, which are going to be formed by university initiators and partners in the fields of science, economy, and politics.

The goal group consisted of future founders of enterprises from the academic environment and innovative enterprises from the cross-border regions of north-eastern Slovenia, Austrian Koroška, and Štajerska (Kärnten, Steiermark). Also in the goal group were young innovative enterprises, stemming from university incubators, Science Park Graz, and the Tovarna podjemov (IRP), as well as all the potential initiation of spin-off enterprises from the academic environment (academic institutions, university professors, scientific co-operators, students), and other innovative enterprises from the cross-border region. The indirect goal groups were the supporting institutions (technological centres, advisory organizations, regional development agencies, chambers of commerce and industry) within the cross-border region and in the EU, which could effectively use the contents of the web applications, and the results of the project.

LEONARDO da VINCI, project: SOCIAL RETURN

Leader: Soffia Gisladottir (FELAGS) Participants: Tanja Kocjan-Stjepanović, Matjaž Debevc, Živa Hohnjec, Rajko

Svečko

Duration: Oct. 2004 to Sept. 2007

The main goal of this innovative pilot-project called “Social Return” was to develop a holistic and multi-disciplined rehabilitation programme and to offer this to disabled individuals, with limited employment capability. The programme should preferably have been carried-out in the participants' local or regional areas. Pilots were set-up in Húsavík (a remote and sparsely populated area in N.E. Iceland), in South Limburg (a densely populated but partially rural region in The Netherlands), in Vilnius, the capital of Lithuania, in the Firenze region of Italy and in the region of Maribor in Slovenia.

This project straightforwardly enhanced the implementation of equal opportunities for disadvantaged people, by applying a holistic, multi-disciplinary approach, customized to the needs of the individual in small scale settings at local levels. People refused to be temporarily lured away from their community and families, as is the case in many of the existing large rehabilitation centres.

RESEARCH PROJECTS


Basic research project

J2-9374-0796-06 Kompleksna analiza visokoresolucijskih slik SAR (Complex analysis of highresolution SAR-images)

Leader: Dr. Dušan Gleich (Faculty of Electrical Engineering and Computer Science)

Participants: Matej Kseneman, Asst. Prof. Dr. Peter Planinšič, Marko Hebar

Financed by: Slovenian Research Agency

The goal of the project is to develop algorithms and a program tool for the analysis of high-resolution complex TeraSAR-X data. The analysis of complex SAR-images is still an non-researched area.

This project researched the efficiency of complex Gauss-Markov models for the analysis of single-look complex SAR-images. We have developed a method, based on the Tikhonen optimization, where the objective minimization function consists of systems response, phasor, and gradient. In the optimization procedure the realization of complex Gauss-Markov field was incorporated into the system response in order to obtain noise-less image and texture parameters. In future we will research, how the de-noising influences the phase and will evaluate the usability of this method for de-noising in the complex domain for practical applications (for example interferogram, humidity estimation etc.).

Duration: Sept. 2005 to Aug. 2007


In this project we researched the field of classifiying optical and single look SAR-images. Methods for eliminating speckle-noise in SAR-images that work in wavelet domain were researched. Using general Gauss-Markov random field as prior and general Markov models, the Bayesian MAP (Maximum A Posterior) cost-function was designed for speckle reduction. Using the texture parameter in the Gauss-Markov model, we created a model which was closest to the given SAR-image. The second method, we developed for speckle reduction, we used an autobinomial model as prior, and very good results were obtained in the objective and subjective sine. We found-out that the with the autobinomial model, the best texture parameters were estimated.

A detailed analysis of newest Gas Metal Arc Welding (GMAW) technologies was done. The research activities are directed towards the MIG/MAG DC welding technologies, such as Surface Tension Transfer (STT) technology. A measuring system for the real-time measuring of welding current and welding voltage was modernized. This system is based upon a PC computer, which is expanded with input-output interface DAQCard-6036E. The MAVS 1.0 software for measurement and analysis of the welding signals is adapted for use with LabVIEW 8.5. We continued with the development of mathematical and simulation models of the MIG/MAG GMAW process. The model MIGMAG.MDL was upgraded with dynamic models of the speed and position variations of the welding droplet. At the same time the simulating dynamic model of the welding power source was developed. The intention is to connect both models in a simulation environment for testing welding power source and

A fuzzy-logic control system for the distillation process is developed. In these types of technological process there is a lot of empirical knowledge, which will be transformed into fuzzy-logic rules and used for computer supported process. This year an on-line estimation algorithm of the alcohol concentration of the condensed product (the distillate) is applied. This method requires, as input data, the measurable temperature of alcoholic vapour. The algorithm is appropriate to use on PLC for real time applications of distillate quality monitoring


and control during the production.

M2-0131 Napredni optični senzorji na osnovi optičnih vlaken za uporabo v obrambnih in civilnih sistemih (Advanced optical sensors based on optical fibres for use in defense and civil systems)

Leader: Assoc. Prof. Dr. Denis Đonlagić (Faculty of Electrical Engineering and Computer Science)

Participants: Dr. Edvard Cibula, Marko Kežmah, Matjaž Linec, Domen Golob Project partners: Mikrobit d.o.o., Optacore d.o.o.


The presented project consists of several smaller projects, intended for use in defence and civil applications. The first part of the project is comprised of several optical fibre sensors for the detection of intruders on secured areas. The first sensor is designed as an optical accelerometer. The accelerometer acts as a highly sensitive seismometer for the detection of ultra low vibrations induced by personnel or vehicle movements over the designated area. A suitable algorithm with accompanying electronics is able to generate an alarm based on these detected vibrations. The second sensor is embedded under secured areas that can be of irregular shapes. The detected signal changes due to the disturbances on the protected surface – the signal is electronically processed and the alarm is generated based on the appropriate algorithm. The third sensor for intrusion detection is based on the deployment of the transmission fibre in the field. The optical fibre is deployed around the protected area where any unauthorized access is detected. The main challenge of the project is the

AU - 50 Laboratory For Electro-Optics and Sensor Systems

development of a special fibre, resilient enough to allow a simple perimeter deployment without the danger of breakage during the deployment. The second challenge is the development of a suitable electronic system that detects intrusion and determines its location.

Perimeter sensor control unit.

The second part of the project is comprised of optical fibre temperature sensors. The first sensor was developed as a quasi-distributed system that incorporates up to 10 temperature measuring sections over one sensor arm of the system. The principle of operation is based


on the polarization properties of light in a special optical fibre that is temperature dependent. The temperature change can be detected using the OTDR which measures losses in different parts of the optical fibre. The main challenges of the project are loss control, sensor manufacturing process, and suitable special fibre usage. The second sensor for temperature monitoring is completely distributed and enables temperature measurements over the entire length of the optical fibre. The sensing principle is based on microdeformations of the optical fibre caused by temperature variations. For this purpose a special optical fibre with copper coating was developed. A special technique enables the formation of a special structure over the entire length of the fibre that causes deformations of the fibre due to temperature changes. The temperature change therefore reflects in the loss properties of the fibre. The third sensor was developed as a quasi-distributed optical temperature sensor based on the evanescent field of multimode fibres. We have successfully designed and tested a single-point sensor within the temperature range of 140 oC. The resulting sensor was then integrated in a quasi-distributed system built out of 10 subsequent sensors. Much of the work on the system has been focused on mode conditioning, loss management and the control of cross-talk between adjacent sensors.

The third part of the project includes the development of special optical fibre sensors for the detection of vehicles and pedestrians. The goal of the project is the development of a system with a longer life-span and preferable smaller deployment costs, than current solutions on the market. Furthermore, the systems will be deployable over wider areas and will have fever limits than current products. The principle of detection is based on the attenuation of light in optical fibres due to the pressure induced by the measured vehicles or pedestrians. Currently, the project is in the phase of live testing in the field.

The last and fourth part of the project is the development and design of special optical fibres that enable simultaneous protection against intrusion and intrusion-detection for fibres in telecommunication systems. Because the optical signal can be quite easily coupled out of the optical fibre (which enables data tapping), a new system is being developed that simultaneously detects and aggravates the data tapping of optical fibres due to more difficult access to the optical fibre core. For this purpose, special optical fibres have been developed.

The aim of this project is to develop an array of Fibre Micro Optical Electro – Mechanical systems. One of the proposed solutions is an optical fibre strain sensor based on a Fabry-Perot resonator in the form of an aerial rift inside the fibre itself. We have developed a working prototype that features linear response, low transmission losses, low temperature dependence, and a simple manufacturing process. The result of this project is an awarded patent in Slovenia.

Miniature optical pressure sensor is based on optical fibres and SiO2 membranes. The developed product could be used in many diverse applications such as biomedicine, different industry fields, etc. Because of the special manufacturing technique the sensor can be tuned for pressure ranges from 0 to 40kPa for uses in medicine, as well as several hundred MPa. The use of SiO2 enables high chemical and temperature resistance.

An optical quasi-distributed pressure sensor is based on a multitude of successive point pressure sensors embedded inside an optical fibre. The composition, therefore, acts as a quasi-distributed pressure sensor. The sensor itself is electrically-passive and very resistant against high temperatures and aggressive media. It is appropriate for high pressure measurements.

The fabrication of micro lenses on top of optical fibres allows integration of MOEMS technology into optical fibres. The manufacturing process is based on the use of appropriate fibres combined with different etching techniques. Micro lenses can be used in optical communication systems, sensor systems, micro optics, etc.

J2-9742 Modeliranje spontanega govora in zelo pregibnih jezikov za podporo vodenim telekomunikacijskim storitvam (Modeling of spontaneous speech and highly inflectional languages for voice driven telecommunication services)

Leader: Asst. Prof. Dr. Andrej Žgank (Faculty of Electrical Engineering and Computer Science)

Participants: Prof. Dr. Zdravko Kačič, Asst. Prof. Dr. Mirjam Sepesy Maučec, Asst. Prof. Dr. Tomaž Rotovnik, Matej Grašič


Development in the area of communication networks also influences the constant demand for improving communication services. One of the most important characteristics of state-of-the-art communication service is usage of user-friendly interfaces. When a voice-driven interface is employed in the service, it is reasonable to use automatic spontaneous speech recognition. This is one of the most challenging tasks in the area of language technologies – the word error rates are still relatively high. The project focuses on research in the area of modelling spontaneous speech. The major disfluences groups included in the modeling are: fillers, word repetitions, sentence restarts, and truncated words. The project’s main goal is to improve speech recognition results.

The voltage sags that appear in distribution networks have different origins. They can be caused by the different events that appear in the distribution network or in high voltage transmission networks. Transmission and distribution networks are normally linked by a transformer. The aim of this study is to find reliable tools for determining the origins of voltage drops, based on current and voltage measurements performed on the transformer terminals connected to the distribution network.

This work evaluates excessive transmission line losses in three-phase systems caused by unbalanced and nonlinear loads. Single-phase systems, where currents and voltages contain exclusively fundamental harmonic components, energy transmission and reciprocal energy exchange between source and load can be adequately treated by the concept of active and reactive power. However, this approach fails when currents and voltages contain higher-order harmonic components or when unbalanced and nonlinear three-phase loads are analyzed. In such cases mathematical tools such as orthogonal decompositions of currents in the time or frequency domains can be applied. Using these tools, it is possible to determine those current components indispensable for energy transmission and those current components that do not contribute to energy transmission and cause excessive transmission losses, which can be avoided.

In this work, orthogonal decomposition of three-phase currents within the time-domain is used to determine those current components indispensable for energy transmission. The


ratio between its RMS (root mean square) value and the RMS value of the original three-phase current is applied to introduce a generalized power factor in the three-phase system. The generalized power factor is used to characterize load-imbalance and the effects of nonlinear load. Excessive transmission losses in a low voltage distribution line are evaluated by case studies performed under different operating conditions.

The electricity system is the largest and most important system for substantial economic activity and societal functioning. It must be designed to enable consumers a prolonged economic, reliable and environmentally-friendly supply of electrical power. Although all three qualities are very important, the reliability of energy supply is undoubtedly the principal. Failure to supply electrical power due to network interruptions may cause great economic disadvantages and impair safety conditions. The question is how much should be invested in creating a network (duplication of elements, spare power and energy) to acquire the desired reliability. The purpose of the reliability theory is to find and establish quantitative connections between investments and failure consequences.

Electricity systems most likely represent the highest technical achievement in human history, from size to variety of usage in technical fields. Electricity systems must be designed to ensure consumers an economical and reliable supply of electrical power, years in advance. However, the future terms of operation can never be fully predicted. Failures and unpredictable load change, short circuits, endurance, isolation materials, unpredictable weather changes (ice, wind, etc.) are only a few of the unpredictable factors, which usually


occur by chance. There is every prospect that decisions made during the design and operation of electricity systems are made under the 'uncertainty condition' and the consequences of any decision can never be fully predicted.

Power failure, as a consequence of network disturbances, may create great economic disadvantages and impair safety conditions. The question is how much should be invested in creating a network (duplication of elements, spare power and energy) to acquire the desired reliability. The purpose of the reliability theory is to find and establish quantitative connections between investments and failure consequences.

There are two types of uncertainty in engineering design and analysis. The first type being the unpredictable conditions under which the system will have to function in the future. The predicted or presumed input quantities of the mathematical model influence the accuracy of results. Mistakes originating from this uncertainty are random; for different input data we would attain different results. The second type originates from simplification of the modelling choice, as well as the mathematical method. It is systematic and appears in the same manner in every repeated calculation.

The probability analysis of reliability offers a quantitative evaluation, for example: whether creating an additional line from the same or different transformer station is legitimate. It may be a criterion for covering expenses – to the company for energy supply or the consumer who finds the extra supply unnecessary.

The quality of electricity supply in every-day life means a minimal number of interruptions and their duration kept to a minimal period of time. A safe and satisfactory device operation is ensured when the devices are connected to a voltage which is within the prescribed tolerances for voltage and frequency. Even short-term interruptions on the basic form of voltage can cause the irregular operation of devices.

Increasing automation in the industry's end-use increases manufacturing process sensitivity to disturbance. The expenses of electrical-quality are, on the open market, very important to consumers, and especially to industry. They, in fact, signify an additional value which can be assured to consumers by the suppliers in order to increase their productivity and the reliability of the production process. The industry must compare the expenses charged by the supplier for quality electricity to the damage caused by production losses or damaged devices.

The development of power electronics and converter techniques is made possible by the


growing use of permanent magnetic motors in modern electric-drives. When compared with other types of electric-motors, permanent magnet motors display superior performances. A crucial part of each permanent magnetic motor is the permanent-magnet. The applied permanent-magnet material, its shape and characteristics substantially influence the characteristics and performances of the entire motor. The goal of this project is to develop an optimization tool which is able to find the optimal permanent-magnet for a given machine design and required operational parameters. This project is the first-step in a systematic approach to the design of permanent magnetic motors, in which evolutionary optimization strategies will be combined with mathematical machine models in order to find permanent-magnets whose geometry, magnetic and thermal properties, and their price will optimally fit the required motors' performances, operational characteristics, and design.

The system of spot welding is a complex electromagnetic device composed of numerous elements. Some elements dominate the influence of operational reliability under the prescribed specifications, which consequently means that there exists the possibility for considerably increasing the system's performances. The existing transformer is oversized. Designing an advanced adaptive-control of the power supply inverter will enable compensation of flux density DC component in the transformer's iron core, which will reduce the dimensions of the transformer considerably.

The goal of the project was to find an optimal transformer design and active control algorithm, which would together lead to transformer reduction and prevent overload conditions on the


primary, at the same time. To reach this goal, analytical and experimental methods were employed. The optimal transformer design and appropriate control of power supply inverter were determined by differential evolution – a stochastic search algorithm.

Energy converters (takening into account are small power generators using fuel, water potential, solar and wind energy as their energy sources) must be implemented and connected to the network to ensure safe operation of converters, networks (and other network devices) and everyone in contact with the devices. The established rules usually suffice. Some devices, however, require additional reflection with certain solutions, such as grounding and disconnecting photovoltaic systems.

Countries have always encountered equal problems and disagreements when it comes to the desires of investors and those of network administrators. The countries of the European Union have tried to overcome this in the case of the smaller devices (up to 16 A per phase) with the 50438 standard. The first draft noted »Fit & Inform« which means 'to build and inform' the administrator. The second draft noted »Inform & Fit« which means to 'inform and build'. Two thirds of the votes were against the latter proposal – the majority prefer to inform, acquire consent, and build. Everyone is aware of the fact that the problem is not in the safety technique – every investor wants to protect their devices as well as the network. The problem is in the procedures, which need to be simplified. The procedures for connecting electric energy consumers are a fine example. A higher number of small power stations would enable a more friendly procedure for connecting distributed generation.


We were chosen to undertake this study because, in addition to our research, we haev built a micro-solar power station and performed technical, as well as legal and administrative requirements, 'live'. It is our concern that administrative procedures vary from company to company and depend mostly on acquaintances and connections, respectively. We had all the inclination and willingness to help which we often did not want to take advantage of on account of the study. Regarding the technique, we did not agree with the suspension of internal technical examination before connection – the safety operations of the network and the converter should be the most important guidance. The last examination, where independent professionals participate, often uncovers certain deficiencies.

Renewable energy sources are the most reliable permanent energy sources on Earth. Annual solar energy which reaches the Earth is 2 895 000 EJ. The supplies of all non-renewable sources amount to 325 300 EJ (oil 8 690 EJ; natural gas 17 280 EJ; uranium 114 000 EJ and coal 185 330 EJ). The current world usage of energy is approximately 425 EJ/year.

The aim of the study was to clarify the procedures and time necessary for the integration of producers of a renewable energy source to the system with regard to European directives on verifying administrative procedures, and our own legislation. There has been a remarkable growth of installed photovoltaic system power in certain other countries and, therefore, the study also compared the procedures of integration in these countries.

Energy storage is important for power stations which ensure electricity in a band (thermal power stations and nuclear power stations) so that they can operate with maximum efficiency. Over many decades pumped-storage hydroelectric power stations have mainly been used for storing large amounts of energy, which can also be expected in the near future. Pumped-storage hydroelectric power stations were first used only for energy storage and covering peaks, whereas now they have become an important and comprehensive control tool. What also needs to be taken into consideration when connecting these energy converters, apart from technical measures and restrictions, is their operational features and the system’s response to them, as well as the existing technical regulations in our country.

The research focused on the power connection of the Kozjak pumped storage hydroelectric power station into the electrical power system. The study covered the analyses of the suggested solutions concerning connection, the choice of the most suitable connection given the location, the effect on the environment and an analysis of the suggested solutions in the light of reliability. In so doing, it based itself on statistics of the losses of similar transformers and overhead lines set in a similar environment (snow, wind, isoceraunical level) and on the data of the supplier of the varspeed generator.

This research was to provide the answers as to whether it is justifiable to set up a parallel overhead line in the area of Zg. Duplek or is it better to upgrade the existing line into a multiple circuit line? How strong is the existing bracing system of the towers? Is it possible to strengthen the towers or is it necessary to build new ones in the common course line? It might be more appropriate to open a system towards Kainachtal and build a double circuit line Hrenca – Kozjak; how reliable is the heavy line along the valley of Drava and if it is even capable of transferring the desired amount of energy?

The problem of electricity quality is an urgent matter for companies distributing electricity due to compensations, which will gradually be introduced in this area. In this respect, the impact of disturbance, which appears in 110 kV systems due to incidents (malfunctions, switching manipulations, as well as openings and closings of larger users), on voltage dips and electricity quality in MV systems, is of crucial importance for companies distributing electricity. The above-mentioned incidents in 110 kV systems may result in disturbance and power failure for sensitive users in MV systems, which could cause great damage.

Within the framework of the study we carried-out an analysis of the legislation within this field and an analysis of current conditions in the world. A dynamic model of the connected systems was constructed, enabling an analysis regarding the impact of disturbances (incidents) arising in 110 kV systems on voltage dips and electricity quality in MV systems, from a physical and legislative viewpoint.

Within the framework of the study, in cooperation with a fund provider in each distributional company’s system, one distribution transformer substation (DTS) was selected, for which an analysis of the impact of conventional incidents at a conventional point of the110 kV system on the medium voltage system was carried-out. The results of the analysis showed the sensitivity of the selected DTS to incidents in the 110 kV system and the suitability of DTS for the connection of highly sensitive users.

The countries in the Western Balkan region have a great, but insufficiently exploited potential of Renewable Energy Sources (RES). The efficient use of RES could significantly contribute


to security of supply within the region and over a wider area. Special care would need to be devoted to innovative and viable solutions for the electricity supply to underdeveloped areas, and areas isolated due to war damage.

The Virtual Balkan Power Center for Advance of Renewable Energy Sources in Western Balkans (VBPC-RES Project) has the following main objectives:

- Transfer of know-how in RES technologies and its implementation for isolated regions

- Identification of main economic and legislative factors influencing investment decisions in RES, including barriers and local specifics, and identification of options for improvement of RES penetration

ZDDZR Zakasnjeno delovanje distančnih zaščitnih relejev ob zemeljskem stiku na nasprotnih zbiralkah v RTP Laško (Delayed operation of distance protective relays during the earth fault at the opposite busbar in DTS Laško)

Leader: Prof. Dr. Bojan Grčar (Faculty of Electrical Engineering and Computer Science)

Participants: Dr. Boštjan Polajžer, Asst. Prof. Dr. Jožef Ritonja

Financed by: ELES Slovenia

Distance protection is the main function for line protection in medium and high-voltage transmission networks. In the field, fast and accurate responses regarding distance relays during faults might be aggravated because of both transients and signal distortions, as well as the consequence of parameters' uncertainties and in the cases of specific network topologies. All this eventually leads to relay missed-operation or considerable delays in tripping command.

This study discusses the delayed operation of several distance protective relays during an earth fault at the 110 kV busbar at the distribution transformer substation (DTS), Laško, on September, 12. .2007, at 1:43 pm. Possible causes for the delayed operation were studied with an analysis of the captured field data, as well as a simulation of the discussed event, using a mathematical model for a 110 kV network in the vicinity of DTS, Laško.

The aim of this study is to determine the causes for the delayed operation of distance relays,

as well as to propose possible new parameter settings.


EPADO Power Distribution Network Automation System - DINAS

Leader: Prof. Dr. Bojan Grčar (Faculty of Electrical Engineering and Computer Science)

Participants: Dr. Boštjan Polajžer, Prof. Dr. Drago Dolinar, Asst. Prof. Dr. Jožef Ritonja

Project partners: Iskra Sistemi d.d. Ljubljana, Iskra Techno R&D, UM-FERI, Faculty of Technical Sciences Novi Sad, Sipronika d.o.o Ljubljana

Financed by: Ministry of Science and Technology of the Republic of Slovenia

The project is assigned to the development, testing and introduction to the market of systems for the automation, protection and restoration in medium voltage networks. The main scope of the project involves the development and implementation of advanced cost-effective software and hardware solutions for control and protection. In the case of damaged lines, the whole system quickly and automatically restores the power supply to the disconnected users. The contribution of FERI to the project concerns the development of a basic algorithms for signal processing and protection, technical support in upgrading existing algorithms, and consulting at all the project's stages.

The system of spot-welding is a complex electromagnetic operation composed of numerous elements. Some elements dominate and influence the reliability of the operation under prescribed specifications, which consequently means that there exists the possibility of a considerable increase the system's performances. The existing transformer is oversized. The design of advanced adaptive control of power supply inverter will enable compensation for the flux density DC component in the transformer's iron core, which will reduce the dimensions of the transformer, considerably.

The goal of the project was to find an optimal transformer design and active control algorithm, which would together lead to transformer reduction and prevention of overload conditions on the primary, at the same time. To reach this goal, analytical and experimental methods were employed. The optimal transformer design and appropriate control of the power supply inverter were determined by differential evolution – a stochastic search algorithm.

Energy storage is important for power stations for ensuring electricity in a band (thermal power stations and nuclear power stations) so that they can operate with maximum efficiency. Over many decades, pumped-storage hydroelectric power stations have mainly been used for storing large amounts of energy, which can also be expected in the near future. Pumped storage hydroelectric power stations were first used only for energy storage and covering peaks, whereas now they have become an important and comprehensive controlling tool. What also needs to be taken into consideration when connecting these energy converters, apart from technical measures and restrictions, are their operational features and the system’s response to them, as well as the existing technical regulations in our country.

Fundamentals and Theory of Electrotechnics Laboratory PE - 35

The research focused on the power connection of the Kozjak pumped storage hydroelectric power station into the electrical power system. The study covered an analysis of the suggested solutions concerning connection, choice of the most suitable connection given the location, the effect on the environment, and analyses of the suggested solutions in the light of reliability. In so doing, it based itself on the statistics for the losses of similar transformers and overhead lines set in a similar environment (snow, wind, isoceraunical level) and on the data of the supplier of the varspeed generator.

The research was to provide the answers as to whether it is justifiable to set up a parallel overhead line in the area of Zg. Duplek or is it better to upgrade the existing line into a multiple circuit line? How strong is the existing bracing system of the towers? Is it possible to strengthen the towers or is it necessary to build new ones in the common course line? It might be more appropriate to open a system towards Kainachtal and build a double circuit line Hrenca – Kozjak? How reliable is the heavy line along the valley of Drava and if it is even capable of transferring the desired amount of energy?

FI switches perform the important role of electrical device users' protection in all kinds of electrical installations. Because of this is used extensively it must work within very hard-working parameters, which must assure independence from the circumstances the switch is placed in. Models of different transformers and FI relay and analysis of the secondary circle of FI switch based on the mentioned models were created within the scope of the task. The time-dependences of some values in the circle, frequency analysis of the circle, and analysis of the sensitivity which defines the influence of single elements on the switching of the relay were discovered.

Because of the more expensive materials used for the production of FI relay, possible cost-reduction would be a reduction in the throw-sout made during production. To reach the mentioned aim, exact analyses of the magnetic and mechanical conditions were made, the concentrated parameters were assessed and influential factors of the magnetic circle together with their influence on the relay’s working reliability were discovered within the scope of the task. Based on the findings about existent relay type imperfections, and demands for technologically simple production, new suggestions for the relays' constructions were made.

The Institute of Robotics performs basic and applied research for the development and building of robotic systems, production automatization, sensor systems, control theory, modelling, identifications, computer process control, industrial robotics, servo-systems, robot controllers, and real-time control systems. We develop advanced-control algorithms for the control of position, speed, and torque with the use of various kinds of executive modules and constructions of robotic mechanisms. We continually develop and build new educational tools for improving the quality of the educational process, and to introduce new technologies to students.

In the Kinematics and Simulation Laboratory, we conduct robot and robotization kinematic control and process simulations. We use both real and simulated controllers and mechanisms. Simulations deal with virtual and real systems and processes. We also investigate nonlinear and robust control for this reason.

In the Power Electronics Laboratory, we study different converter structures, which can be applied in different areas such as the automotive industry, and alternative enrgy sources based on fuell cell technology. We develop new converter structures and advanced control approaches based on digitalization of the control algorithm by different microcontrollers and different FPGA circuits. The laboratory is well-connected with very important industrial companies in Slovenia such as Iskra

The main issues of the project work starts with the feasibility study and energy storage principles. A review in the area of power electronics converters is also being done. Due to the limited space in vehicles thermal issues are the main point of interests. The problem of power buffering could be solved by the use of a super-capacitor or by using batteries. In both cases, thermal models of them are needed. Mathematical models of converters, Li-Ion batteries, Fuel-cell and Super-capacitor are investigated in order to evaluate the system's behaviour. Power management between different energy sources is being studied with the possibility of applying an algorithm by using DSP unit TMS320 or appropriate FPGA circuits. As a result of this feasibility study the optimal control for power management will be proposed.

Modern systems need AC and DC voltages of different voltage levels for their operation. When power supply sources from public power supply systems are unavailable at specific locations (deserts, hills, different military environments …) it is necessary to find solutions in autonomous power supply systems. Due to the nature of available alternative sources such as photo voltaic systems, hydro-sources, diesel generators, appropriate power converter systems are necessary for supplying the chosen load.

The converters included in this system must enable a bi-directional mode of operation. In some cases, the available energy is higher than the load's needs and the energy should be stored in batteries which are connected to the system by bi-directional converter.

The proposed system is composed of 6 different units, which are three-phase AC-DC, bidirectional single- phase AC-DC, bi-directional high voltage DC-DC, bi-directional low voltage DC-DC, constant frequency three-phase DC-AC, and single-phase DC-AC converters. All converters need local control units and also units which will control the power flows among them.

The main objective of the project is to conduct research on innovative and cost competitive highly-integrated thermal-electric hybrid configurations for mass-produced vehicles for the European market from 2010/2012.

Requirements:

•“social needs” (lower consumption and acoustic/regulated emissions reduction) and

•“customer demands” (enhanced performance, improved drivability, high thermal comfort, acceptable cost for purchase and operation).

System analysis and verification tests will be performed for the split hybrid powertrains with two different hybrid vehicle platforms and for a combined one with a dedicated test bench. The outcome will be used for a complete assessment and comparison (both at technical level and in terms of cost).

Low-power BLDC motors or step motors are used extensively for low-cost mechatronic systems in the automotive industry. For so-called interior applications, it is important that such mechatronic systems generate noise as less as possible. Noise is related to torque smoothness on the motor's axis. We have developed an Analyzer of step motors' dynamics that enable measurements and analyses of typical characteristics regarding step-motors. The analyzer can be used within the development phase, as well as in final product testing.

The main issues of the project work starts with a feasibility study and energy storage principles. A review in the area of power electronic converters is also being done. Due to the limited space in vehicles, thermal issues are the main point of interest. The problem of power buffering could be solved by using a super-capacitor or by using batteries. In both cases thermal models of them are needed. Mathematical models of converters, L-Ion batteries, Fuel-cell and Super-capacitor were investigated in order to evaluate the system's behavior. Power management between different energy sources is being studied with the possibility of applying an algorithm by using DSP unit TMS320 or appropriate FPGA circuits. The result of this feasibility study regarding the optimal control for power management will be performed.

Modern systems need AC and DC voltages of different voltage levels for their operation. When power supply sources from public power supply systems are unavailable at specific location (deserts, hills, different military environments …) it is necessary to find solutions in autonomous power supply systems. Due to the nature available alternative sources such as are photo voltaic systems, hydro-sources, diesel generators, appropriate power converter systems are necessary for supplying the chosen load.

The converters included in this system must enable bi-directional mode of operation. In some cases the available energy is higher than the load needs and the energy should be stored in batteries which are introduced in the system by a bi-directional converter.


The proposed system consists of 6 different units, such as three-phase AC-DC, bidirectional single- phase AC/DC, bi-directional high voltage DC-DC, bi-directional low voltage DC-DC, constant frequency three-phase DC-AC and single-phase DC-AC converters. All converters need local control units and also units which will control power flows among them.

SOCRATES ERASMUS Project MARE – Joint European Master Degree Programme »Remote Engineering«

Leader: Michael Auer (Carinthia Tech Institute) Participants: Živa Hohnjec, Rajko Svečko, Andrej Knuplež, Matjaž Debevc, Prof.

Dr. Riko Šafarič


The main task of the project MARE is to elaborate a completely new joint curriculum in the field of »Remote Engineering«. The programme is planned as a joint Master's degree programme.

The uses of virtual and remote laboratories and workplaces is one of future directions for advanced teleworking / e-working environments especially in engineering and science but also in all other fields of the society. This would also provide a benefit for people with special needs and people working from their homes.

All over the world there is a lack of specialists in this field and the number of needed specialists will have to increase dramatically over the next few years.

The general objective of the curriculum is to mediate fundamentals, applications and experiences in the field of remote engineering by an interdisciplinary approach in combination with »learning by doing« phases. In this way we create in Europe unique possibilities for studying »Remote Engineering«.

Technology-enhanced learning in a dual mode will be the central didactic approach.

The study programme is open for students from all-over and outside Europe and requires a Bachelor's degree in engineering or in the science of informatics.

Graduates will be able to work in remote working environments and to develop such environments.

This project represents an important contribution to the information Society Policies (Lisbon Agenda) and the eEurope Action.

Financed by: Slovenian Research Agency, National Office for Research and Technology, Ministry of Higher Education, Science and Technology of the Republic of Slovenia

The project is aimed at dealing with a) robot systems and control, and b) product modeling and intelligent computing by methods that enable the description of a complete functionality of mechatronic systems due to interaction between all of them. Computer-based engineering methods are being developed with our partners by composing an integrated solution. The methods are in the areas of: a) system specification, b) modeling of robot systems, b) control of robots for typical application purposes, and e) fuzzy and intelligent control structures. Project goals involve obtaining models that are required for many different functions developed at different levels of abstraction so that proof of concept can be accomplished within design phases, thus requiring code generation for rapid prototyping, as well as production code. Our research is based on a paradigm for improving rapid prototyping and holistic design of control in robotic and automation systems that will encompass flexible manufacturing systems and modern robot-control methods. It is expected to involve not only conventional robot-control but also vision-based control and bilateral teleoperation.

We will study both major forms of inflammatory bowel diseases (IBD), ulcerative colitis and Crohn disease, IBD-associated neoplasia (IBDNs) and colorectal cancer (CRC). We will focus on identification of novel single nucleotide polymorphisms (SNPs) associated with higher risk for complex gastrointestinal diseases and different individual response to treatment. We will describe new genes and molecular pathways involved in pathogenesis and treatment response. We will develop new bioinformatic and statistical genetic tools for best candidate gene selection. We will develop a new approach for identifying functional SNPs in regulatory cis-acting regions based on allele specific expression in lymphoblastoid cell lines from CEPH families and segregation analysis. The database with genes showing most significant allele specific expression will be used for our disease association study and will be

avaiable on the internet to the scientific community for other disease association studies. We will also describe molecular alterations, including somatic mutations, methylation status and global gene expression profile in adenomas from IBDN patients, tumors from CRC patients and biopsies from IBD patients during standard treatment with corticosteroids and immunosuppresives and treatment with monoclonal antibody inhibitor against TNF alfa (Inflaximab). We will provide molecular markers for IBDN patients with increased risk for CRC development. We will correlate genetic data with CRC patients prognosis and survival. We will functionally characterize genes and proteins most significantly associated with disease.

We will establish a comprehensive follow-up patients database and bioinformatic tools for finding statistical correlations between molecular genetic and clinicopathological data included in the database. We will conduct case-control study of patients with gastrointestinal complex diseases and matching healthy individuals using candidate gene, genome-wide haplotype and linkage disequilibrium association approaches. We will use Taqman method for high-throughput genotyping. Candidate genes genotyped will include drug metabolizing enzymes (phase 1 and phase 2), drug transporters and genes potentially involved in pathogenesis selected in our study using bioinformatics and gene expression approaches. We will use oligo-microarrays, quantitative real time PCR (Taqman) and imunohistochemistry for expression profiling.

METOD - MetaTool for Educational platform Design

Leader: Prof. Dr. Peter Kokol (Faculty of Electrical Engineering and Computer Science)

Participants: Mateja Verlič, Gregor Štiglic, Matej Mertik, Assoc. Prof. Dr. Milan Zorman, Asst. Prof. Dr. Petra Povalej

Project partners: Intelligent Computer Systems Centre, IDEC S.A., Secondary school of health-care, II. high school Maribor, School of textiles Maribor, Gjovik College – Higher Education Institution, Faculty of Electrical Engineering and Computer Science, ZEUS Consulting S.A.-LogicDIS Group, Western Greece Development Center, Department Educational Sciences and Media Research, Czech Technical University Prague, TelabGesbR, The Centre for interdisciplinary and multidisciplinary research and studies

Duration: Oct. 2004 to Apr. 2007

The rapid advancement in ICT including multimedia, virtual reality, intelligent systems and telecommunications (i.e. Internet) enabled the development of computer-supported educational platforms (CSET) which can improve the quality, user friendliness and accessibility of training, education and lifelong learning. The major advantage of such type of learning is the immediate feedback to the learner. There is no waiting period for correction and, therefore, learners do not “practice their mistakes”. The various channels, through which the educational information is brought to the student largely improves efficiency by employing both brain hemispheres. In addition, computer-supported platforms are the basis for supporting or even developing new innovative types of learning (innovative pedagogy), i.e. problem based learning, evidence based learning, etc. But literature overview, recent research supported by consortium own experiences gained in various projects and results of some pre-studies noted various disadvantages of current CSETs, most important being:

• that after the novelty effect of drill and practice wears off the motivational power is lost,

• the platforms are static - the educators or trainees can not adapt them to specific environments (for example disabled people), changed educational requirements, new educational programmes, etc.,

• normally, the educators or trainees can not develop such platforms by themselves, because of the lack of knowledge, the lack of time, non existence of the platform development paradigm, etc.


The specific aims of the projects are:

• To design a general computer supported educational platform development paradigm.

• To develop a framework for integrating machine learning and machine intelligence in the educational platforms, enabling self adaptation according to special educators and trainees needs and characteristics.

• To design a metatool enabling all kind of educators (including parents or senior family members) to develop, adapt and maintain their own educational platforms without great effort.

• To provide courses, conferences and workshops for target groups on above three topics.

• To disseminate the project achievements to a wide audience using both ICT and conventional approaches.

The long-term aims are to improve the skills and competences of people by the integration of new computer-supported educational platforms specially designed for specific environments and requirements into the training and educational process. The paradigm and metatool will enable the building of educational and training environments, supporting and developing innovative pedagogical approaches and curricula, accelerate e-Learning and lifelong learning, encourage the development of teaching and learning materials, and building virtual learning environments. As a result the quality, user friendliness and accessibility of training and educational processes will be significantly improved.

Concurrently, ICT enables us to make these educational platforms accessible to a variety of different target groups (trainees, employed and unemployed workers, people with disabilities, etc) with the additional advantages of asynchronous learning, distant learning and lifelong acquisition of skills and competencies.

Citing the above two program objectives will be supported »to improve the skills and competencies of people, …« and »to improve the quality of, and access to, continuing vocational training …« together with the call priority “New technologies”. Wider EU initiatives such as lifelong learning, innovative pedagogy, e–Learning supporting basic objectives of learning (such as active citizenship, personal fulfilment, social inclusion and employability/adaptability) will be also taken into account. They will be addressed using all accessible new information technologies such as: Internet, wireless communication, ultra high performance computers, virtual reality, intelligent systems, agent technology and all the related knowledge. The environment and the platforms will be accessible to all citizens through the internet and both will be user friendly, flexible and adaptable for all levels of education, for all ICT skill levels and also for people with disabilities.

Detection of pathological changes in surface electromyograms using statistical and entropy-based approaches (Bilateral Slovenian-Cypriot project)

Leader: Prof. Dr. Damjan Zazula (Faculty of Electrical Engineering and Computer Science)

Participants: Dr. Matjaž Divjak; Asst. Prof. Dr. Aleš Holobar; Breda Jesenšek Papež, MSc; Rok Istenič

Project partners: University of Cyprus, Nicosia

Financed by: Cyprus Research Promotion Foundation, Slovenian Research Agency



A bilateral research project whose aim is computer-based diagnosing of surface electromyograms (sEMG) was approved for the period between Oct. 2005 and Dec. 2007. This project collaboration links four research groups, two from Cyprus (Department of Computer Science, University of Cyprus, and Cyprus Institute for Neurology and Genetics, both in Nicosia) and two from Slovenia (beside the System Software Laboratory, there is also a group from the Neurology Department in the Teaching Hospital of Maribor).

The figure depicts the force measuring device for isometric contraction of an elbow-joint. The device has a changable angle of elbow-joint. The recorded force is depicted on the computer's monitor, where subjects see the target force, which must be followed. Surface EMG is recorded simultaneously with force to study the dependency of force and EMG signals.

In 2007 two Slovenian researchers visited Cyprus and three Cypriot researchers visited Slovenia.

Slovenian researcher Rok Istenič visited Cyprus in July 2007. He attended a Summer school


for doctoral students, organized by the Department of Computer Science, University of Cyprus and presented his work entitled ''Classification of Neuromuscular Disorders Using Wavelets and Entropy Metrics on Surface Electromyograms''.

Another Slovenian visit to Cyprus was made by prof. dr. Damjan Zazula in September 2007. The project activities took place at the Department of Computer Science of the University of Cyprus and at the Cyprus Institute of Neurology and Genetics, both in Nicosia. The main topics discussed were as follows:

– getting acquainted with the equipment and acquisition facilities for surface EMGs as developed within the project framework to obtain clinical measurements on the standard EMG devices;

– a lecture given by the Slovenian visitor on the project topic entitled Can Clinical Practice Benefit by High-Resolution Surface Electromyograms?

– an agreement on the final processing of the so-far recorded surface EMG signals, representation of the results and their dissemination in the form of conference and journal papers.

In 2007 three Cypriot researchers, dr. Prodromos Kaplanis, dr. Christodoulos Christodoulou and Maria Xyda, MSc. visited Slovenia during conference MEDICON 2007 in Ljubljana. In this conference our joint paper was presented, by authors M. Xyda, C. Pattichis, P. Kaplanis, C. Christodoulou and D. Zazula, entitled "Model based decomposition of MUAPS into their constituent SFEAPS".

Leader: Assoc. Prof. Dr. Milan Ojsteršek (Faculty of Electrical Engineering and Computer Science)

Participants: Sandi Pohorec; Ervin Schaff, MSc

Financed by: Ministry of Agriculture, Forestry and Food

Farmers, who want to trade their crops, products or meat as ecological products, have to breed, grow or produce them in a way that meets strict ecological criteria. Within this project, the system of the previous project has been upgraded to enable support for more-control organizations. They operate via a central server at the Ministry of Agriculture providing central control.

The EKOFARM3 was upgraded in 2007 with the history of farms' and farmers' data change, with the automation of transferring this data between control organizations. In addition, several data bases were merged into single one for all organizations and a unified login was provided via LDAP system. The application is more compatible with the MS Office package. The level of report building automation is improved.

Portal infrastructure facilitates creating, integrating, and managing information documents. This way, we can achieve higher efficiency of accessing such information since users spend less-time to find, use, and analyze information. In addition, administrators spend less-time helping users. The basic features of portals are: document management, information search, integration of application services and content within information system with external information systems, cross-referencing content and services, providing collaboration services, information categorization, providing independance between data and its presentation in various media, multi-lingua information presentation, authentication and authorization of access to data and services and security consideration, and personalization with customization. The portal is being updated with new functionality on a regular basis.

Last year, the portal infrastructure was upgraded with several new functionalities, such as web-selling, environmental data presentation (meteorological data, air quality, underground water), submitting citizen initiatives, improved search engine (lower security risk), virtual and actual deleting of content and items, provision of news via RSS, and archiving support.

Participants: Domen Mongus, Blaž Repnik Project partners: IGEA, d.o.o

Financed by: IGEA, d.o.o

This project was performed as a series of smaller subprojects agreed in a form of subcontracts to the principal contract. Development, configuration and usage of the server-side application Geoserver for presentation of raster and vector data by the help of an image mosaic were the main project goals. Among the main tasks solved inside the project, we emphasize: authentication for WMS requests and usage of the WFS authentication server, translation of the Geoserver source code into Jdeveloper, in order to enable functionality in Oracle IAS environment, integration of security system in Geoserver, expansion of MapBuilder functionality, integration of data-store for MrSID format in Geoserver infrastructure and update of data-store for ArcSDE spatial data, implementation of WFS-T specifications for spatial data manipulation for usage in Oracle Spatial and ArcSDE, the support for EPSG projection for system of coordinates used in Slovenia, and development of tools for state maps and DOF infrastructure for Geoserver.


M2-0138 Razvoj in integracija prikaza lokacije klicočega v GIS (Development and integration of a system for locating caller in GIS)


Participants: Blaž Repnik Project partners: Faculty of Electrical Engineering, University of Ljubljana, IGEA, d.o.o


The aim of this project is determining caller location, when calling number 112. In case of an accident, the location of the caller is of crucial importance. This information should be related with the existing system GIS_UJME. In this way the reaction time of the intervention groups is reduced. During this project, the possibilities of passing the geo-location of the caller from a stationary, mobile, and IP phone of all providers located in Slovenia was investigated. After


this, the prototype has been implemented.

M2-0141 Razvoj sistema za simuliranje realistične pokrajine za bojno usposabljanje posadk (Development of a system for visualization of realistic terrain required for training battle crews)

Leader: Dr. Gregor Klajnšek (Faculty of Electrical Engineering and Computer Science)

Participants: Asst. Prof. Dr. Sebastian Krivograd, Bojan Rupnik, Dr. Mirko Zadravec, Blaž Repnik

Project partners: EM. Tronic d.o.o.

Financed by: Slovenian Research Agency, Ministry of Defence

The goal of the project is to create a software system that would support as realistic a representation of terrain as possible using existing hardware in the middle price range. The model of the terrain is based upon the digital model of relief, but the user can also change the geometry of the terrain through an external application. Beside the realistic representation of the terrain, the system supports visualization of static (trees, houses, electrical wiring, …) and dynamic objects (targets) that can be found on the real training polygon. In 2007 we implemented the majority of the required systems (visualization system, physics engine) and developed an interactive scene editor.

J1-7218 Algoritmi za analizo dodeljevanja lokacij (Algorithms for analysing facility location)

Leader: Justo Sergio Cabello (Institute for Mathematics, Physics and Mechanics)

Participants: Asst. Prof. Dr. Krista Rizman Žalik, Prof. Dr. Borut Žalik Project partners: Institute for Mathematics, Physics and Mechanics


In this project, we consider problems arising in facility location analysis and we will provide efficient algorithmical solutions for them. Whenever facilities have to be placed or removed, we can search for a model to quantitatively measure the impact of the decision, and the best decision translates into an optimization problem. The functions to optimize may be simple ones, but in most real applications we have to deal with a trade-off between different criteria. When we aim to efficient algorithms for solving these different problems, the algorithms must be tailored to each particular problem, and different problems call for drastically different algorithmical solutions. The techniques used in our project will be mainly drawn from the fields of computational geometry, graph algorithms and data structures.

15725 CDT application development

Leader: Vid Domiter (Faculty of Electrical Engineering and Computer Science)

Financed by: Silhouette FX, USA

We have adapted an implementation of our algorithm for constrained Delaunay triangulation to meet the requirements of the SilhouetteFX enterprise from USA. The algorithm constructs a triangular mesh from the set of input points and line segments. Each triangle should fulfil the weak Delaunay criterion which assures maximality of the minimal interior angle. Consequently, the resulting triangular mesh consists of “nice” triangles. The algorithm is based on sweep-line strategy. It achieves high-operational speed, low-memory requirements and low dependence on point and edge distribution.

An informal cooperation between both research groups in the research areas of algorithms for computer graphics and computational geometry was established as early as 2002. Before the common project started, this cooperation had already resulted in two original scientific papers. Through the project, we strengthen our cooperation, focused on the development of new methods, which are numerically stable and computationally efficient. We have identified three research topics as the basis for further cooperation: general voxel traversing algorithm, algorithms for polygon clipping and set operations between regions, approximation and compression of 3D free-formed surface models. In 2007, two original scientific papers were published as a result of this bilateral project, and the third one is currently in the review process.

Contemporary society is highly dependent on information communication technologies and their applications. The efficiency of using them is related to the successful usage and fusion of technical/technological and business/organizational knowledge and skills. Therefore, studies of Informatics, as well as Informatics and technologies of communications, in addition to some foundation knowledge that is common to computing (such as computer networks, algorithms, operation systems, programming, and databases) offers in-depth knowledge relating to the analysis, design, and implementation of information systems, strategic planning of informatics, and organization. The acquired knowledge enables successful project management and usage of modern methodologies for the development and reengineering of information systems. The main mission of informatics is to assure (better) business decision making, which is a consequence of modelling, modernizing, and improving the efficiency of business processes. To achieve this, it is reasonable to rest on existing comprehensions, reference models, and applications of methods and technologies for knowledge management. Recognizing the importance of systematic approaches, usage of standards and establishment of quality assurance systems is reflected in better information systems and business solutions. The significance of information security and protection originates from the characteristics of contemporary operations – openness and interoperability. In addition to technology-related aspects of integration informatics need to be capable of managing the gap between information technologies and different groups of users. The connection role of informatics requires them to be familiar with knowledge and skills related to communication methods and technologies, collaboration and team work and, nevertheless, they

BI-HU/06-07-011 Application of OO Metrics to Estimate .NET Project Software Size

Leader: Assoc. Prof. Dr. Marjan Heričko (Faculty of Electrical Engineering and Computer Science)

Participants: Asst. Prof. Dr. Aleš Živkovič; Luka Pavlič Project partners: Eötvös Loránd University, Faculty of Informatics

The focus of this project would be a practical application of metrics suitable for object, component and aspect-oriented development in a specific target environment, namely Microsoft .NET. The concrete environment is needed to build a bridge between two metrics groups - source code metrics on one side and high-level project metrics on the other side. Within the project, a subgroup of source code metrics that has the greatest impact and higher correlation coefficient with high level metrics for estimating project size will be defined, collected, and tested to formally-prove their importance. In a more general sense, the project will define a framework for a software metrics plan that can be used within software companies and further applied on .NET environment. The framework itself will focus on specific metrics used within software projects to estimate project size. However the results and the framework itself are expected to be applicable to other metric families as well. For the practical part of the project, conceptual definition of architecture will be established that will enable the end user to easily compose a tool for metrics gathering and analysis in .NET environment. The analysis will be founded on UML models composed in Visio. The UML models will then be used to calculate project size in function points. The correctness of results will be statistically proven using actual hours; further on the correlation between function points and selected source-code metrics for .NET environment will be investigated.



Applied project

L5 6708-0592-04 Referenčni model za nadaljnje vključevanje e-poslovanja v pravni sistem (Referential model for further integration of e-business into the juridical system)


Duration: Feb. 2004 to Jan. 2007

This interdisciplinary research from the domains of law and informatics was financed by the Faculty of Law. Its goals were to further develop e-business and to increase confidence in it. Some contracts that are made over the electronic mail require a third independent party – an e-notary – to ensure proper judical protection. The primary aim of the research is to deal with external operation of jurisdiction and notaries, and with capabilities for composing e-notarial documents and for processing e-certifications. This research addressed judicial-regulating as well as technological challenges, and laid a foundation for introducing a referential model of the appropriate information architecture enabling efficient design and implementation of IT solutions. On the basis of the unified infrastructure and architecture, high integrability and connectivity will be assured, regardless of the heterogeneity of applied programming tools and platforms. This kind of open architecture, which relies on standards, as are XML and web services, is a necessary prerequisite for successful integration into international electronic business structures, such as SEEM (»Single European Electronic Market«).

A clinical practice guideline (GPC) represents a standard set of recommendations for the clinical handling of the patients affection regarding certain pathology; for example, in cases of cardiac insufficiency. Its adoption on the part of sanitary professionals repels directly in the quality of patient assistance, fostering the standardization of interventions. In spite of the unquestionable interest of its application and use, the number of sanitary professionals who act according to the recommendations of the guidelines would be below the desirable level. There are two main reasons that explain this low impact: 1) the difficulty of adapting GPCs standard to particular cases of each sanitary centre and 2) the low relationship between the GPC and the job stream of the professionals. Both factors would influence negatively the viewpoint of doctors and other sanitary professionals, making them reluctant to use them in clinical decision making. In order to solve this, more operative versions of GPCs have been introduced, known as Care Pathways (CPs).

This project proposes the use of Intelligent Systems in the processes of acquiring, formalizing, adaptation, and using and assessing knowledge models that describe CPs. In this project, the clinical pathways are not generated directly from the GPCs, but from electronic protocols, that represent versions of the adapted guidelines when they are made specific to the particular healthcare circumstances. The CPs obtained could be used by intelligent computer science distributed systems to facilitate decision making that allows e-care in the context of a new Information Society.

Leader: Dr. Izidor Golob (Faculty of Electrical Engineering and Computer Science)

Participants: Mirjam Bonačič, Andrej Sevčnikar, Prof. Dr. Tatjana Welzer Družovec

Financed by: Viris, d. o. o.

Duration: Oct. 2006 to Sept. 2007


Preparation of an information system, as well as the usage of plans for natural and other disasters and their preparation, have shown, that the system should not only be uniformed, but also has to be established. In this way it would be possible to optimize and integrate currently separated processes for collection, storing, aggregation and updating. The result of the project is a conceptual (entitety-relational) model and an integrated plan for collection, aggregation and updating.

Data mining is an interdisciplinary research area. The results of data mining find a variety of applications, for instance: in bioinformatics, economy, software engineering, etc. The creation of an intelligent environment poses several challenges, many of which can be solved using intelligent data analysis into organizational, business and industrial processes. Automated programs for learning are needed for the machines to become easy-to-use instruments of daily life. Information handling must move from today’s data-storage perspective to future data analysis perspective. The challenge is to integrate the data mining into database management systems and using them as a unit in the knowledge management systems. The objective of the project is to contribute to the integration of developed data mining techniques into intelligent systems.

The aim is to promote sharing and dissemination of information and state-of-the-art on current data mining and knowledge discovery methods, and to use new processing and storage paradigm to support data and processing intensive process. The goal is to incorporate the research results into the daily usage.

University undergraduate Media Communication Studies is a multidisciplinary study programme that integrates knowledge from the areas of radio- and TV-production, information systems, graphical communication (computer graphics, art and design), and telecommunication.

The multidisciplinary programme provides students with all the technological and organizational knowledge they need for their professional work and further professional and academic development. Having in mind the development of press- and electronic-media in the future, the university level of studies in Media Communication provides the foundation, not only for performing work in radio, TV and production houses, but prepares students for a career in marketing companies, in interactive media publishing companies, in Internet-service providers, in industry, especially in developing company marketing material and selling products or services on the Internet. In the first years of studies emphasis is given to the theoretical part, while the practical work is carried out in the final years. The programme is, in part, carried-out in media houses and similar environments to gain experience with specific working areas.

The programme has been developed carefully, taking into account the development of disciplines, covered by the programme, considering the specifics of Slovenia and the regions. The curriculum is harmonized with similar programmes from all over the world.

The knowledge, gained through leading and carrying out various projects by the institutes’ members in the above-mentioned areas, is, therefore, directly incorporated into the educational process.

The project goal is to improve and accelerate the quality of development and production in the fields of multimedia in all organizations and companies that deal with development, production, distribution, and implementation of multimedia products and programs. To reach this goal we are organizing an exchange of experience and best practices in Europe with the participation of people involved in the development and production of multimedia (production, design, didactization, distribution, and pedagogical usability).

Our requirements for quality focus in the following fields:

1. pedagogical content (Content Management, goals, aims, and feasibility of education)

2. didactical and methodological feasibility (management, environment, design, and learning feasibility)

3. design (mediality)

4. usability (interface).


Our network focuses on the following tasks and activities:

- experience exchange by implementation of European workshops

- forum for quality and further education by implementation of European project seminars

- production and distribution of quality suggestions and criteria

- documentation of quality' multimedia products (data base)

-distribution of best-practice multimedia products (in internet, by newsletter, fairs)

- setting up a transnational internet forum for teachers and evaluation internet forum for learners.

Duration: May to Dec. 2007

In 2007, from evening hours of September 22nd to morning hours of September 23rd at altogether 32 research institutions in various EU member states there was a one night event called Researcher's Night. The event aimed to present and promote research, above all researchers and the research profession. In 2007 the common motive was "Researchers are among us" and it aimed at demysticating the researcher's profession. The events focused on presenting the lives of researchers apart from the working place, so the general public was able to understand that researchers are ordinary people and that among ordinary people there are many researchers.

NATO Former Yugoslavia/Slovenia: The Role Of The Mass Media In The Peace-Building Process


Participants: Zala Volčič, Andrew Calabrese Project partners: NATO Public Diplomacy Division

Financed by: NATO Public Diplomacy Division

Duration: Dec. 2004 to Dec. 2007

This project is concerned with contemporary information and communication technologies’ transformations in the former Yugoslav countries. The specific focus is on media, culture and communication, in terms of both security and policy activities. The central hypothesis is that


new media developments - information and communication technologies - are creating a new transnational cultural order that is of specific importance in the countries of the former Yugoslavia after the end of wars and changes. However, political, economic and cultural rebuilding can take place only in an environment where civil relations are subjected to a democratization process. Firstly, one has to create a space where information and communication technologies are contributing constructively to the rebuilding of society. The project proposes to investigate the human, national and regional dimensions of post-conflict peace-building challenges; civil relations in war-torn societies; democratization processes and the role of the media; and the role of local and external actors in meeting the challenge of sustainable post-conflict security sector reform. First results already confirm some hypothesis.
