FOREWORD

At the Faculty of Electrical Engineering and Computer Science, we are organized into eight institutes: Institute of Automation, Institute of Electronics and Telecommunication, Institute of Informatics, Institute of Mathematics and Physics, Institute of Media Communications, Institute of Power Engineering, Institute of Computer Science, and Institute of Robotics. Institutes consist of laboratories, which are specialized for individual research fields. Institutes beside the scientific-research work also care for individual study programmes at the university and vocational professional study programmes and in that way they most effectively carry over recognition from the research to the pedagogical work. Above all, students in higher grades are often involved in researches in the laboratories. In such, with practical work on the real problems, they strengthen theoretical knowledge, and at the same time they gain the experience and strengthen the engineering intuitive knowledge, which is so important for a creative engineer and researcher. Our graduates, because of previously mentioned, are valued and sought for.

In 2008, we have begun to carry out the second year of Bologna study programme. Just so, we have prepared the programmes of the second Bologna cycle, which we will begin to carry out in 2010/11 school year, and accredited the third Bologna cycle, which we will begin to carry out in 2009/10. We hope that the new generations of engineers will also achieve a high level of knowledge. We will strive to include the students, under the Bologna study programme, as soon as possible into the research work as well, and support their creativity and self motivation.

Difficulties related to finances are still present, yet the current annual report proves that our faculty is very involved in research and developing projects both nationally and internationally. Achievements of our scientific-research work are presented at the international scientific conferences and in the most prestigious scientific journals. We have introduced the new model of keeping the accounts of received funds at the faculty and consequently opened the possibility for the most successful groups, laboratories and individuals to carry out their desires and ambitions.

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.

In the study year 2009/10, we are going to start with the 1st study year of the 3rd Bologna level of doctoral studies of the following programmes:

- Electrical Engineering, - Computer Science, and - Media Communication.

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 2008 is collated in the sequel.

1. Telematic

Programme unit head: Prof. Dr. Žarko Čučej

The program group comprises of employees from Laboratory for signal processing and remote control, Laboratory for system and control, and Laboratory for digital and information systems.

Scientific disciplines: informatics, metrics, computer science, systems, telecommunications.

Telematics – telecommunications and informatics in synergy – is a foundation of modern information society. It enables services that change the paradigm of personal life, industry and connection with the world. Company Ultra d.o.o. and the UM, FERI, founders of the program Telematics, have joined their development and market goals on one hand, and research and pedagogical skills on the other hand, with the aim to encourage research in the field of telecommunications and informatics and to speed the transfer of knowledge and accomplishments from academics to industry. We move our activities from the broader context of telematics to the following three areas:

- capture, store and transfer of information, where research is performed in the areas of multidimensional, multispeed signal processing, statistical methods, modeling, information transmission, remote sensoring, information mining, etc.

- quality and safety of living, where we perform research and develop techniques for mobile remote control and monitoring of environment, people’s health, mobile interactive access to information, data and knowledge;

- services, where we perform research, but most of all develop applications for electronic payment systems, traffic monitoring and managing, safety insurance, distant learning.

These researches and planned activities for transferring knowledge and services have multilayer significance for Slovenia:

a. Permanent social-economic and cultural development

Wide world, products and services of telematics represent a market niche with high growth. Many Slovenian companies build their strategy based on telematics’ products and services. They share common characteristics – high technology, high added value and fast development. In order to keep up to date, accelerated research and continued development of qualitative undergraduate and postgraduate education is necessary, especially for the science disciplines, on which telematics is based. Telematics can also open new possibilities


in the cultural sphere. With digital, interactive diffusion of radio, TV and other multimedia channels, it enables access to top cultural activities to wider public.

b. Technological development

Growth of telematics and its services is based on using knowledge and high technology. If we want to keep up with the world competition, research in this field, closely tied with industry and academics is absolutely necessary. Such researches stimulate development of wireless communication devices, systems for capturing, archiving, processing and transfer of information. All these devices, knowledge and algorithms directly and indirectly impact the country's technological development.

c. Increasing national identity and preservation of natural wealth and cultural heritage

These days, mastering telematics divides nations, which maintain and develop its identity and develop natural wealth and cultural heritage, as well as those nations that are only a in a shadow of developed societies. Knowledge in general, which is basic for telematic products and services doesn't burden the environment, but rather spreads knowledge and culture, and enables a more quality living. Telematics will definitely contribute to the national entity and culture through planned construction of virtual laboratories, digital libraries and centre for remote control.

Abroad telematics is developing rapidly. For example, enormous standardization efforts for MPEG 4, MPEG 7 and MPEG 21 in the area of multimedia, UMTS and WI-FI in the area of telecommunication, information systems construction and research of information mining carry huge potential. Similar situation can be found in the area of remote sensing, mobile remote control of environment, people with special needs, and in the area of electronic payment as a pillar of e-store. In all these fields, we collaborate with the leading centres in Europe, such as DLR/DFD, partners in European programs like Socrates and Leonardo. By publishing in the leading journals in JCR bases, collaborating with and organizing international workshops and conferences, international program committees and bilateral projects, we contribute in our own way to the treasure of world knowledge.

2. Control of electromechanical systems

Programme unit head: Prof. Dr. Drago Dolinar

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

Scientific disciplines: Automation, Electrical Engineering, Electromagnetism.

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. The research subjects are closely incorporated into a domestic industry and social infrastructure where both 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 of the dynamic modelling of electromagnetic devices and complex technical systems (analytical models). A new concept for IM torque control has been 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 has been a 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 has been used. Part of the project has been related to the detection, location and classification of faults in the distribution networks. Several methods for fast and accurate estimation of loop-parameters have been 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 of 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 from 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 the most developed countries 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 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 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 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 that 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 the 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 a 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 improved competitive positions of our companies. The improved quality of control also means 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 of 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, along with their combinations and the transfer of technologies into practical use.

The results of research in the field of fiber-optic mode filters will enable single-mode connections with the use of fibers, which would enable multimode operation. In the area of fiber-optic sensors the main issue of our research is FP interferometers and low-cost sensors on the basis of plastic fibers. We successfully produce various prototypes of sensors.

Studies into the possibilities of modified modulation techniques, where 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 to 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, 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. Experimental system with the PEM fuel cell has been 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 the international markets as a 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 less expensive 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 the most important topic. The importance of this area is represented by a large number of research groups at the best universities and institutes worldwide, which deal with problematics. Research into the control of electrical drives is focused on applications in the automotive industry, where reliable and energy-efficient operation of drives is a key issue.

Research efforts in the area of event systems are connected to 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 less expansive replacement 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, automation systems, 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 still dominate the field of CNC systems, although open solutions using the PC are emerging. The main 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 upgrade, extension and interoperability. Additionally, open architecture shortens the design cycles, increases productivity, reduces interruption of production time, 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 suppression 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 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 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 were 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 from the Microcomputer Systems Laboratory, Digital Signal Processing Laboratory, Electronic Systems Laboratory and Digital and Information Systems Laboratory.

Scientific disciplines: Signal Processing, Telecommunication Engineering.

In 2008, 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, were 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 synchronization system used for animation of avatar Maja has been developed. The baseline Slovenian Broadcast News continuous speech recognition system has been enhanced. Acoustic models for the Babilon speech-to-speech translation system have also been upgraded.

In continuous speech recognition, the work has been primarily oriented towards the enhancement of search algorithms. The recognition accuracy of the large vocabulary continuous speech recognition system of Slovenian language has been evaluated on the Slovenian Broadcast News BNSI speech database, and has been further increased.

Language modelling focused on broadcast news and parliamentary speech domains. The language models with vocabularies of 20k and 60k words have been further enhanced and are ready for integration into the large vocabulary continuous Slovenian speech recognition system.

In 2007, basic research activities for development of speech-to-speech translation components continued, and the target application of communication scenario of orientation in urban foreign environment has been accomplished.

Within the framework of the programmed part of system correctness assurance, in 2008, we have continued with the development of our tool for automatic verification of reactive systems EST (Efficient Symbolic Tools). We have started to develop, implement, and test algorithms for the so-called “on-the-fly” model, checking for formulae of the ACTLW logic. They have been shown as more efficient than the currently supported global model checking, at least for some kinds of systems. We have developed approaches for a 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 from 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, IS/IT Architectures, 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 such as methodological aspects of IS, databases and data warehouses development; quality assurance strategies; information technology support for inter-organizational 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, the architectural design, implementation, verification, and validation of IS and IT management. The emphasis is on the object- and component-oriented approach, and on service-based architecture with semantic component and context- and aspect-dependent behaviour. One of the key issues is the assurance of information services' integration, which also address 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 that support information technology in inter-organizational business operations, primarily between businesses as well as for customers and employees. The main goal is the construction of inter-organizational 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 a research to define new approaches that introduce 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 from Fundamentals and Theory of Electrotechnics Laboratory, Applied Electromagnetics Laboratory and Electrical Machines Laboratory.

Scientific disciplines: Electrical Engineering, Electromagnetism.

The research programme of “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 specificity, these areas are treated parallel within the framework of the programme, however 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 mathematical solving of these, very complex problems, we choose a finite element method and a boundary element method. In 2008, we intensively researched the field of electrical machines.

The influence of an electromagnetic field on the environment, particularly its influence on people and on different electrical devices, is becoming a more and more important research area. Last year, we continued a model development, 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 development of a complete model, because in this way we can come closer to the real conditions, because only real conditions make it possible to actually estimate the electromagnetic field's influence on its surroundings. We have also intensely researched the process of an atmospheric discharge during a lightning strike and we have developed the appropriate mathematical model.


Knowledge of the real materials' properties is very important to solve field problems using numerical methods. The development of measuring methods pointed towards measuring methods for accurate determination of real materials' characteristics, and accurately determin losses in the materials. Parallel with that, we have developed the mathematical model to consider the hysteresis curve at FEM magnetic field calculation.

The third part of the research programme focuses on the development of models, which are useful by the solving of inverse problems in electrotechnics. Last year, we have 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 six laboratories from the Faculty of Electrical Engineering and Computer Science of Maribor; Computer Architecture and Languages Laboratory, Computer Graphics and Artificial Intelligence Laboratory, System Software Laboratory, Heterogeneous Computer Systems Laboratory, Geometric Modelling and Multimedia Algorithms Laboratory, and Programming Methodologies Laboratory.

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

A five-year period of funding of Programme Units ended in 2008. An overview of the results achieved during this period is, therefore, given in the sequel. From 2004 to 2008, the Programme Unit was financed by the amount of 3.5 FTE. In addition, 35 international projects and 78 projects for the Slovenian industry and institutions were carried out. According to the SICRIS database, 54 scientific papers were published in SCI-journals (15.4/FTE), 48 papers in the second rank of journals (13.7/FTE), 190 contributions to scientific conferences (54.3/FTE), 7 chapters in books edited by foreign scientific publishers (2/FTE), and 4 patents (1.1/FTE).

The Programme Unit members cope with a wider field of computing and information technologies, which supports the research to be carried out at two levels. Profound scientific work is carried out separately by individual research subfields, but it is coordinated in such a way that it leads to the overall development objective of the unit and links the complementary research achievements. In the period from 2004 to 2008, such a cohesive objective was the development of intelligent web services. They are described separately from the scientific achievements as follows.


1. Intelligent Web Services

Already in 2004, a Group for Intelligent Service was established within the Programme Unit, which links members of all participating laboratories in the program. Its primary mission was to develop and tailor a middleware layer for services - a backbone, and then gradually integrate it with emerging intelligent services. The following activities were carried out:

– A middleware layer was designed and developed, i.e. a backbone, to connect the services, which enabled logging the intelligent services into the entry server, setting up secure connections and sessions, termination and rerunning the sessions, design and control of user interface, running the services on remote systems, monitoring and control of remote services, exchanging the parameters and results between an intelligent service and the entry server, storing the partial results in the entry server, and keep a log on the server’s and intelligent services’ operation;

– Development and integration of the intelligent service for generating compilers (LISA); – Development and inclusion of the intelligent service for the creation of graphic images

and landscapes using fractals and noises.

– Development and incorporation of the intelligent service for the segmentation digital image sequences;

– Development and incorporation of the intelligent service for 3D triangular mesh compression; and

– Development and deployment of the computer chess intelligent service BBChess.

In the past two years we have developed a middleware tool that supports intelligent services with machine learning. This addition allows each service to learn about their users, how it is deployed and what the user responses to the service operation are. From the data collected, the service identifies behavioural patterns and adapts its further operation to these findings.

2. Scientific Research

In the following paragraphs, our particular scientific achievements are briefly described in the fields of programming languages and grammars, domain-specific languages, evolutionary computations, computer graphics, modelling and simulation of eco-systems, geometric modelling, control optimization, decomposition of superimposed signals, medical image processing, computer vision, multimedia and data compression, web portals and digital libraries, and digital lexicon of the Slovene language.

In the field of theory of programming languages two algorithms for context-free grammar inference have been developed. The first one is based on evolutionary computations and introduces specific crossover and mutation, specific construction of initial population and search for frequent patterns. The second algorithm is based on heuristic search of all possible derivation trees. Good results


have been achieved with both algorithms on simple domain-specific languages. Grammar inference algorithm has been also applied in the area of model-driven engineering (MDE) for metamodel reconstruction from model samples. Patterns for various phases of domain-specific language (DSL) development have been investigated and guidelines for DSL implementation have been proposed. New framework for automatic generation of DSL debuggers has been developed.

We have developed an object-oriented programming language ZERO. The language is statically typed and enables structural and behavioural run-time reflection. Metaprogramming model is based on metaclasses, which enable introspection and run-time modification. The language provides a unified object model with methods being objects as well. Such a model makes anonymous methods and higher-order methods possible in an imperative language, as well as their specialization and almost arbitrary composition of programs at run-time.

In the field of evolutionary algorithms, we have developed a self-adaptive differential evolution algorithm. We have also used differential evolution in the development of our own chess program BBChess.

We have researched algorithms for interactive breeding of ecosystems and evolutionary parameters control with entropy and self-adaptation at local search. We have developed interactive interface for evolutionary process in the programme EcoMod, which enables simulation of natural disasters and use of evolutionary operators for a forestation: selection (adding, deleting), crossover (gene information exchange), mutation (new species, random variation), and environmental dynamics (variation of each condition or variation of terrain for reassessment of conditions).

In the field of surface flattening, we have developed and evaluated two different algorithms for elimination of flat pattern overlapping in the case of elastic plane materials. We have studied the algorithms for the tree modelling and applied them to the problem of an overgrown forest area simulation. In particular, a biological model utilizing Ellenberg’s ecological factors has been developed, along with algorithms for geometric modelling of trees and algorithms for the modelling of trees with hypertextures. Our research work has also dealt with the problem of cloud volume modelling. We developed the SURFMOD tool, which implements the most important parametric graphical construction methods. This tool enables comparison of selected methods using the same data. We have also developed the FlattGen tool, which incorporates the commonest methods for surface flattening into a plane. Teaching of methods is based on their mutual comparison. We introduced a new efficient algorithm for the reconstruction of nonintersecting 3D curves from a sufficiently dense sample, using Euclidean minimal-spanning trees.

Dealing with multi-criteria optimisation problems, we have studied combinations of fuzzy logic and genetic algorithms. We have proposed a special adaptation of island genetic algorithm with mixed crossover to optimise the selection of multiple project teams with possibly conflicting requirements.


An application for teaching correct procedures in the case of accidents, involving hazardous materials for the Administration for Civil Protection and Disaster Relief, has been built. The scenarios of five most frequent accidents involving hazardous matter have been developed together with the correct handling procedures. The application has been designed in the way that additional scenarios can be incorporated easily. Merging of photos of real environments with computer generated objects and figures significantly augments the teaching results.

The most important achievement in the field of the decomposition of superimposed signals is the introduction of a new procedure based on the convolution kernel compensation (CKC). This approach proved to be very successful in the decomposition of surface electromyograms (EMG). Its reliability and efficacy surpasses all other approaches known worldwide, which has been confirmed in experiments in several research laboratories abroad.

We have also developed effective procedures for the analysis of 3D ultrasonic medical examinations and the automated recognition of the changes and growth of tissues through a series of examinations. We have refined approaches to 3D image registration, cellular neural networks, and a method based on support vector machines. The results have proved to be useful in clinical practice applied to artificial fertilization procedures at the University Medical Centre of Maribor. We have enhanced detection of organs and tissues with the use of haptics. A system for automatic segmentation of a sequence of medical images and reconstruction of 3D objects has been introduced to support virtual tactile sensations using a haptic device when “walking through” an organ or tissue.

We have also studied motion and 3D tracking by using a stereo camera, and have developed three comparable transformation approaches for registering the camera co-ordinate system and a magnetic tracking device. We have evaluated the sensitivity of all three approaches and identified ranges in which each co-ordinate transformation is dominant.

Computer transmission and storing of 3D (voxel) and geometric data requires the best data compression algorithms as possible. This problem is often encountered in medicine (tomographic and magnetic resonance examinations) or geodesy. We have derived several methods that efficiently compress practically unlimited amounts of voxel data with minimal data storage consumption. We have introduced lossless compression of DICOM medical data, compression of time-variant (4D) voxel data. And, recently, a promising voxel data compression method based on preliminary data segmentation. We have also dealt with the topology compression of meshes aimed at finite elements method (FEM) analyses. We have studied, developed and optimised the approaches for multiresolution compression, simplification, transmission and visualization of large sets of triangles, quadrilaterals, blocks and prisms. Our original algorithm for the lossless compression of manifold hexahedral meshes topology, using vertex degrees, has proved competitive, regarding efficiency, with the best existing method for compressing this kind of data. We have also utilized triangular meshes for the raster image compression. Each pixel represents a vertex in the triangular mesh. The algorithm first uses vertex decimation and, after that, some algorithm for triangular mesh compression. In raster images, we also pay special attention to compression of edges, contours and other “vector” objects. As a result of our cooperation with foreign partners, several efficient chain-code-based algorithms have been developed and


published. Recently, we have also tackled large point clouds compression, and developed an efficient method for compressing LIDAR (Light Detection And Ranging) data.

In the field of geometric modelling and computational geometry, for more efficient geometric search, we have built algorithms based on heuristics. The obtained speed-up has been in some cases even over 400% in comparison with other existing algorithms. Research in alternative data structures for efficient triangulation in a plane has also been performed. We have tested several implementations, such as deterministic skip lists, (a, b)-trees and red-black trees. These led to a Delaunay triangulation algorithm, which is almost independent of the input point distribution. We have 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 integration of these into our incremental Delaunay triangulation algorithm. A new algorithm for constrained Delaunay triangulation, based on sweep-line paradigm, has been developed, too. Also, this algorithm overcomes remaining solutions. We have also introduced benchmarks for Delaunay triangulation algorithms. In addition, we have proposed original solutions for spatial clustering, for cloth modelling and real-time simulation, for an efficient approximation of arbitrary curves and surfaces using intersecting polylines and meshes, for a powerful constructive geometric constraint solver with in-built redundancy and inconsistency detection facilities, for surface reconstruction from a cloud of points, for missing pixels restoration in a designedly corrupted raster image, for adaptive geometric data sorting, and for LIDAR points classification. Our knowledge has been successfully built in the applications for users of geographic information systems (GIS).

We have developed a web portal, which represents the bond between the content and services. Portal consists of internal services (authentication, authorisation, personalisation, integration services and user interface) and external services (i.e. our intelligent services). We focus to improve the ranking results of search engine by topical content. We have upgraded an intelligent integration service, which connects services referring to user requests and current situation. In the last year we have also created an answering system that can respond to the questions raised in the Slovenian language. Its operation is based on morphological dictionary, which contains around 300,000 basic word forms (lemmas), and a little more than eight million of their extracts. For our domain, we have composed a domain-specific dictionary, which has been built in part automatically through the analysis of web documents. At the University of Maribor, we have implemented a digital library and built portals based on the infrastructure that means our own development.

In the past two years, we have developed a multi-agent simulator of household appliances in a joint project with the Gorenje manufacturer from Velenje. At the same time we have founded a development centre located at the Faculty of Electrical Engineering and Computer Science of Maribor that will support research on Gorenje’s connected appliances. The research topics will be control and communication components to assist the elderly and deploy intelligent services in their home devices.

101-MCT Moderna teorija vodenja (Modern Control Theory

Leader: Rajko Svečko (Faculty of Electrical Engineering and Computer Science)

Participants: Zdenko Mezgec, Amor Chowdhury, Andrej Sarjaš, Andrej Knuplež

Controller design problems have been originally formulated in the frequency domain. The main tools used during the early phases of research for this class of problems have been operator and approximation theory, spectral factorization, and (Youla) parametrization, leading initially to rather complicated (high-dimensional) optimal or sub-optimal (under the H-∞ norm) controllers. Riccati equations of the type that arise in linear-quadratic differential games play a key role. These findings have prompted further accelerated research on the topic, for more direct time-domain (state-space) derivation of these results. Among different time-domain approaches to this class of worst-case design problems, the one that uses the framework of dynamic (differential) game theory seems to be the most natural. This is because the original H-∞ -optimal control problem (in its equivalent time-domain formulation) is in fact a minimax optimization problem, and is therefore a zero-sum game, where the controller can be viewed as the minimizing player and disturbance as the maximizing player. Using this framework, our research focuses on a complete theory that encompasses continuous-time as well as discrete-time systems, finite as well as infinite horizons, and several different measurement schemes. We also discuss extensions of linear theory to nonlinear systems, and derivation of lower-dimensional controllers for systems with regularly and singularly perturbed dynamics. Currently we are engaged in several problems such as:

1. Development of the robust controller synthesis method for systems where the performances' demand is asymptotic tracking to the sinus reference signal.

2. Order minimization of synthesis weight functions.

3. Study of the connection between the pole placement and the H-∞ synthesis.

StuDis - Inclusive High Edication System development

Leader: Alenka Bera, Society of students with disabilities Participants: Matjaž Debevc, Primož Kosec Project partners: UM-FERI, UM-FOV, UM-FS, UM-PF Financed by: Fund for non-governmental and non-profit organizations in Slovenia

When the number of disabled people who decide to study increases, improving the accessibility of faculty and architectural institutions of higher education also increases. Much less is done to fix the information and communication barriers, which largely hinder the


process of study and can be inclusive of the methods of study and teaching of reduced or eliminated. The project aims at removing barriers that arise in the process of teaching / learning and thus improve the opportunities for successful studies of students with disabilities as well as contribute to improve the quality of the academic process for all students. Activities and results of the project will be devoted to administrative and academic staff at universities and higher education institutions and students to people with disabilities. Project results will contribute to the greater awareness on the specific needs of students with disabilities, the obstacles faced in the preparation of strategies for overcoming previously mentioned obstacles. Personnel will provide the knowledge and skills in the teaching of how to overcome barriers, how to adapt the study process and how to deal with disabled students. The latter may not be in the equivalent position with the other students that the level of knowledge and training equivalent to other disabled students. Today, in practice, it happens that the disabled students not be required to perform certain obligations, because the staff is not aware of the possible adjustment of devices, etc.. That would allow the student the equivalent of knowledge acquisition and provision of study commitments. In the project, we carried out an analysis of the situation and treatment procedures to the participating colleges, formed to standardize the treatment of students with disabilities for the entire University of Maribor, develop training materials and training staff also performed at the colleges, participating in the project. We believe that the results of this project will be transferred to other universities and higher education, and thus contribute to the development objectives of higher education in Slovenia. Project results will also be transferable to other levels and structures of education, both in basic as well as in secondary education in lifelong learning.

LEONARDO DA VINCI: DEAFVOC 2 - Transfer of Curricula for Vocational Language Education of the Deaf in Europe

Leader: Annemari Laurento, The Finnish association of the Deaf Participants: Matjaž Debevc, Primož Kosec Project partners: Irish Deaf Society, University of Klagenfurt, Opetushallitus Finland,

UM-FERI Financed by: European Union, UM-FERI

The Deaf belong to a European minority, which has to fight over the right to their own language, cultural heritage and identity. They, too, often face the danger of falling out of education and working life because of poor language skills. In the previous project DEAFVOC www.deafvoc.fi, a model curricula “Sign Language as a Mother Tongue” and “Written Language as a Second Language for the Deaf” was developed to be used in language teaching at vocational schools. During the project DEAFVOC, it became obvious that in addition to the curricula, teaching material is also very much needed. Hence the reason the main target group (teachers and students) is quite small in each country, cooperation on European level is really necessary.


The main objectives of the proposed project DEAFVOC 2 are 1) adaptation of the model curricula “Sign Language as a Mother Tongue” and “Written Language as a Second Language for the Deaf”, 2) facilitation of innovative new teaching materials and methods by drawing materials together, and by gathering didactically relevant information on teaching of sign language and written language for the Deaf in the project countries.

The main outcomes of the project are nationally modified versions of the curricula and models of different kind of teaching materials to be analysed and compared.

Feedback from the main target group is already gained during the project when the curricula and teaching materials are piloted in vocational schools and training courses for the teachers. This ensures participation of the end-users in the project.

The project aims at having a positive impact on the current situation of the language teaching in vocational education for the Deaf in EU-countries, in order to guarantee the Deaf a possibility to study their mother tongue – sign language – as well as a national written language. Bilingual education will ensure the students better possibilities in vocational education and working life.

The Deafvoc 2 consortium includes:

1 two strong Deaf NGOs, the Finnish Association of the Deaf (FAD) and the Irish Deaf Society (IDS)

2 two universities; Klagenfurt University (ZGH) and Maribor University (UM), experienced in Deaf education, linguistic questions, research on ICT assisted teaching for students with special needs. ZGH was responsible of curriculum “Written Language as a Second Language for the Deaf” in the previous DEAFVOC project.

3 the Finnish National Board of Education(FNBE) is the educational authority with international contacts and grass-root level communication with vocational institutes. FNBE was responsible of the curriculum “Sign Language as a Mother Tongue” in the previous DEAFVOC project.

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 in 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 a major need for all Serbian partner universities to establish studies leading to a M.Sc. degree that will educate future experts for design and implementation of e-learning. Those 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 retrain 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 to 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 anticipates e-learning, the need for qualified experts in that field is self-evident and therefore creating M.Sc. curriculum in e-learning is essential. These experts will be required to be active advocates for e-learning in their organizations and they will need to manage significant change processes that affect the entire organization and society as a whole.

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

- A major goal from 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 the curriculum development, purchasing of a new equipment for supporting the educational process will be enabled by project realisation.

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

- The implementation of this curriculum at partner universities will produce qualyfied experts in the field of e-learning and will provide an environment for teacher's and student's mobility.

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

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


SCM-T017B06-UKR 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 eLearning are being discussed by the academic community more than a year. At present, this problem is being switched from discourse and theoretical searches of eLearning development to its real implementation in Ukraine. The question of eLearning “being or not being” is not an actual one any more. In the whole world, eLearning has occupied its own niche in the educational sphere, and actuality of this form of education is obvious – eLearning is called to play a vital role in the formation and evolution of 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 of ideas, knowledge, and educational systems.

Ukraine’s state interest, reflected in the Law of Ukraine on “Higher School”, the Programme of Informatisation of Ukraine’s Education, the Concept of DE Development in Ukraine and other strategic documents, including the ones of the Ministry of Education and Science of Ukraine (MESU), facilitate the process of introduction of information integrated technologies covering the whole life cycles of educational services and is a very important and necessary element of the process of reforming the structure and content of higher education in Ukraine. Namely on the basis of intensive introduction of innovative means of eLearning competitive market of educational services is being formed, and universities are the chain in this process.

This project is devoted to the development of eLearning in the UA system of higher education through improving university eLearning systems. The actuality of problems of improving eLearning systems in the partner universities is well grounded, since the situation nowadays is that UA universities have definite developments in the area of applying eLearning technologies in the training process (availability of technical base, DE centers, own virtual training environment, experience of working in eLearning system and management of educational programmes), but cannot always use and develop eLearning resources in their universities. The project is based on the fact that the participating universities understand and


take into account the fact that the process of introducing eLearning technologies at the HEI itself must be carried out with the application of programme-objective approach, since it requires to solve a set of tasks connected with creating organisational, staff, financial, methodical, programme, technical and other types of provisions. However, before applying such approach for improving university eLearning system to its full extent, university staff must direct its efforts towards revealing (every UA partner HEI will carry out a SWOT-analysis of eLearning resources condition and define priorities) and target solving problems connected to the wide usage of eLearning technologies in the training process by means of raising professional competence of administrators, managers and teachers working under conditions of open educational technologies.

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

The main distinctive feature of our project is that purposeful training of administrators, managers and teachers from the participating in the project UA universities will result in practical implementation of their local projects to improve university eLearning system. Thus, UA universities staff members will be able, not only to create a real operating eLearning system, but having advanced their professional competence, to develop an optimum model of eLearning system, which can be offered to other UA HEIs creating/improving their eLearning systems. A package of recommendations on improving university eLearning system will be elaborated with the assistance of EU experts, MESU representatives and disseminated at the national level. Taking into account that MESU strategy in the area of UA eLearning is aimed at its developing and rests, first of all, on 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 eLearning system at the educational institutions of all levels in all regions of Ukraine. In such way, the feedback between the universities and the MESU will be ensured, which will allow assurance of a qualitative decision-making process while working out strategic documents in the field of development of eLearnign system in Ukraine.

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


Participants: Sinja Leskovec, Živa Hohnjec Project partners: University of Maribor, University of Belgrade, University of Tuzla,


Graz University of Technology

Financed by: Austrian Science and Research Liaison

One of the key issues in establishing and promoting Information and Knowledge Society in the South East Europe 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 such 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 existing equipment, educational labour shortage), or slow growing economies that do not allow improvements in the educational system.

One of the possibilities to remedy these issues is to establish a network-based educational platform that is accessible to a wide basis of citizens of the Western Balkan, regardless of their age, gender, prior ICT knowledge, literacy level, nationality, or social status. Such educational platform would serve as media and content delivery platform for educational content on ICT. However, the educational purpose can be only seen as a kick-off for a wider social, networking, and community purpose. As experiences from other developing countries show [Hassebroek 2001, Marquez 2006, Rahal 2004] network educational platforms that included community aspects attracted a larger number of users, initiated discussion and collaboration, caused network effect, and in turn resulted in improved increase in ICT literacy.

In establishing such a platform, E-Learning can play a crucial role. 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 transfer of that knowledge in another cultural and in fact multi-national context need to be carefully considered and developed. 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.

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 program.

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 fields of the society. This would also provide a benefit for people with special needs and people working from their home.

All over the world, there is a lack of specialists in this field and the number of needed specialists will increase dramatically in the next 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 a unique possibility to study »Remote Engineering«.

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

The study program is open for students from all over and outside Europe and requires a bachelor degree in engineering or in 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.

International project

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 disabled and through those better conditions to enter the labour market

b) Goal – to raise educational level of young disabled population

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

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

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 does not have a common development strategy, and e-learning is developed partially and independently. For that reason, an initiative from the University of Tuzla for developing joint e-learning material was welcomed. University of Tuzla already created an e-learning centre.

Recently there are also visible solutions for realization of laboratory exercises on distance in real-time and with video control. Hyper video as an additional connection form of media within video is also becoming an attractive element of e-learning. In the 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 eLearning lecture 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 a big popularity, and also in Serbia and Montenegro. It is evident that e-learning in Serbia and Montenegro does not have common development strategy, and is developing partialy and independently. For that reason, it would be very valuable to use results that Slovenian researchers 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 in joint cooperation of Slovenian researchers in developing e-learning strategy in Serbia and Montenegro. Researchers and pedagogical staff from Serbia and Montenegro now need 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 to provide strategy for efficient training and education about e-learning.

Particular goal, based on the previous experience of European institutions and also University of Maribor, would be the creation of University e-learning centre. Its role would be to provide pedagogical, technical, economical and legal support in developing e-learning. With regard that the UM FERI has the experience in creation of its Centre for distance education at the University of Maribor, it would all together increase activity of the current centre, introducing new and state-of-the-art methods in supporting the development of e-learning. On the other side, Technical Faculty in Cacak has necessary facilities and equipment for succesfull centre activities.

As the outcome of this project, inovative 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, special project goal would be to conceive and establish possible joint research in e-learning area and obtain more possibilities for application for European projects.

Participants: Assoc. Prof. Dr. Boris Tovornik, Asst. Prof. Dr. Nenad Muškinja, Božidar Bratina

Project partners: Varstroj d.d., Welding Institute

Financed by: Ministry of Higher Education, Science and Technology of the Republic of Slovenia, Varstroj, d. d.

In the R & D project, we focused on the development of welding devices based on the modern inverter technology, which will allow standard welding modes, synergic operation and one of the advanced forms of short circuit welding. We continued with the development of a dynamic model of inverter based welding power source and of the dynamic model of droplet transfer in the short circuit (MIG/MAG) welding process. The simulation model enables analysis of various inverter structures and development of an alternative control method for efficient control of short circuit current time responses. Technology measurements were performed, where we have used the improved measurement equipment and a new version of measurement software application (MAVS). We have acquired and analysed the time responses of the welding signal by MIG/MAG welding process with short circuit material transfer. Upon completion of the study of new welding technologies, we carried out further

Process Automation Laboratory AU - 39

welding experiments with LINCOLN PW 455M/STT welding power source. Analysis of measurements confirmed the expected time response characteristics of the welding short circuit current. On the basis of simulation and experimental results, we investigated the possible modifications of the conventional welding power source, which will allow the application of improved procedures of short circuit welding. Improved methods are not feasible with the conventional welding power source with inverter in primary windings due to their high inductance, which hinders the rapid turn off of the short circuit current. In Varstroj R&D unit they have performed some of their own experimental designs of inverter circuits and appropriate control units.

Participants: Dr. Edvard Cibula, Matjaž Linec, Marko Kežmah, Simon Pevec, Silvija Buzeti

Project partners: Optacore d.o.o.

Financed by: Roctest FISO Technologies Incorporated

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

Miniature optical pressure sensor is based on optical fibers 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.

Optical quasi-distributed pressure sensor is based on a multitude of successive point pressure sensors embedded inside an optical fiber. The composition, therefore, acts as a

Laboratory For Electro-Optics and Sensor Systems AU - 49

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

The presented project consists of several smaller projects, intended for use in defense and civil applications. The first part of the project is comprised of several optical fiber sensors for 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 fiber in the field. The optical fiber is deployed around the protected area where any unauthorized access is detected. The main challenge of the project is the development of a special fiber 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.

The second part of the project is comprised of optical fiber 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

AU - 50 Laboratory For Electro-Optics and Sensor Systems

on the polarization properties of light in a special optical fiber that is temperature dependent. The temperature change can be detected using the OTDR which measures losses in different parts of the optical fiber. The main challenges of the project are loss control, sensor manufacturing process and suitable special fiber usage. The second sensor for temperature monitoring is completely distributed and enables temperature measurements over the entire length of the optical fiber. The sensing principle is based on microdeformations of the optical fiber caused by temperature variations. For this purpose a special optical fiber with copper coating was developed. A special technique enables the formation of a special structure over the entire length of the fiber that causes deformations of the fiber due to temperature changes. The temperature change therefore reflects in the loss properties of the fiber. The third sensor was developed as a quasi-distributed optical temperature sensor based on the evanescent field of multimode fibers. We have successfully designed and tested a single point sensor with temperature range of 100 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 on cross talk between adjacent sensors.

The third part of the project includes the development of special optical fiber 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 preferably smaller deployment costs than current solutions on the market. Furthermore, the system is deployable on wider areas and has fever limits than current products. The principle of detection is based on the attenuation of light in optical fibers due to the pressure induced by the measured vehicles or pedestrians.

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

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 to improve communication services. One of the most important characteristics of state-of-the-art communication service is usage of user friendly interface. When 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 was focused on research in the area of modeling spontaneous speech. The major disfluencies groups included in the modeling were: fillers, word repetitions, sentence restarts and truncated words. The project’s main goal is to improve speech recognition results.

Number of grid tight photovoltaic power plants is increasing. They normally operate connected to the low surge impedance distribution network without any problems. However, when they are connected to the high surge impedance distribution network they could cause problems. The converter and photovoltaic power plant control algorithms introduce subharmonic components in the currents that causes also subharmonic components in line


voltages. They all together increase losses related to the power transmission in the distribution network. The impact of photovoltaic power plants on the distribution network is evaluated in the time and in the frequency domain.

Electricity systems most likely represent the highest technical achievement in the human history, from size to the variety of use of technical fields. Electricity systems must be designed to ensure consumers economical and reliable supply of electric power, years in advance. However, the future terms of operation can never be fully predicted. Failures and an 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 the decisions made during the design and operation of electricity systems have been 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 into 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 that originate from this uncertainty are random; for different input data we would attain different results. The second type originates from the simplification of the model choice, as well as the mathematical method. It is systematic and appears in the same manner as 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 the expenses – to the company for energy supply or the consumer who finds the extra supply unnecessary.

Method for planning and operation of power system, which considers changes of operational conditions, is described in this work. Input parameters - node loads in the load flow probability calculation are passed as a probability function that results from the former operation careful analysis.

Based on the described method calculation, software has been developed. Node voltages, load flows, element currents and losses are calculated from node loads random vector, considering connectedness among working and reactive power of the same and adjoining nodes. Results (node voltages, load flows, currents and losses) are shown with the expected value (arithmetical mean value) and mean square deviation in tabulated form. At the same time, elements (lines, transformers) load control according to the natural (lines) and thermic power have been performed. Load flow histograms are real value of this method.

HRČEK HRANILNIKI ENERGIJE KOT ČRPALNE ELEKTRARNE (Energy Storage Systems as Pumped Storage Hydro Plants

Can energy storage systems function in an electricity network as pumped storage plants?

Renewable energy sources (e.g. the wind and the sun) are inconstant, almost unreliable source of electricity, the emphasis being on energy. An electricity network is usually prone to unexpected power failures due to a lack of power. It is the energy storage systems, which are able to compete with classic energy converters. At the moment, the most inexpensive »storage system« is the network itself, which means the number and the size of the renewable sources, respectively, included in the system, is limited.

The aim of the research is to examine, which actual storage systems are available, their efficiency and prices. The supply of the storage system to the network can be concentrated or dispersed throughout the network. Economic viability can be determined from the price discrepancy.

With the growing prices of fossil fuels (the price of oil has increased by factor ten in the last seven years) and small price growth of electricity (an increase by factor two in the last seven years) a considerable increase of electricity prices can be expected. The sun shines during the day when energy consumption is at its highest while the constant wind blows stronger and more often during the night. With the wind power plants, when is a storage system economically justifiable?

Which discrepancy between the low (night) and high (daytime) price of electricity economically justifies an energy storage system? A systematic solution must be drawn up to enable the sale of energy from the storage system.

The research defines, in greater detail, the advantages and drawbacks of possibilities of inclusion of ČHE into the electricity transmission and distribution network from technical aspects for methods of execution:

400 kV overhead line

400 kV underground cable

In the context of the research, other aspects like implementation, operating reliability, maintenance and life span are considered. By drawing up bases for the definition of the affects on the environment, the developer will collaborate with experts from the fields of spatial planning and nature, who will be provided by the customer.

The conclusions of individual parts of the research are used for the implementation of the comparison of individual methods of execution, which is the integral part of the research where possible corridors of integration of ČHE Kozjak into the electricity transmission system of the Republic of Slovenia, according to their type, (free-space/cable) are taken into account.

In the context of the research, there is a separately handled variation of the 400 kV overhead line in the existing corridor, south of Maribor where there are three 110 kV overhead lines today, taking into consideration the cabling of the previous, and separate treatment of the 400 kV cable alignment.

The switch manipulation electric arc occurs in an electrical power system . The occurrence of an electrical arc causes various inconveniences such as heating contacts, corrosion of contacts, which leads to a reduction of the life of switchgear components. Electric arcs are extinguished by various systems such as fire extinguishing with compressed air, SF6 gas, vacuum and isolation oils. All these methods help reduce the effects of electric arcs however they do not prevent the occurrence of an electrical arc. Some methods of quenching are also ecologically challenged. Therefore, ways to prevent or reduce the electric arc have been researched for a long time. Much is expected from the use of electronic elements.

In the task, we have reviewed the previous research work done in this area first. Then we investigated the reducing effect of the electrical arc on elements of the switching apparatus capable of restricting the flow at the time of switching or interruption of alternating currents. Theoretical work has been confirmed by laboratory testing.

The proposed project focuses on the transformer, more specifically on its magnetically nonlinear dynamic model. In order to achieve acceptable agreement between the measured responses and those calculated by the dynamic model, the magnetically nonlinear characteristic of transformer’s iron core has to be determined. The characteristic can be determined through a test and measurements, which could be a problem when tested transformer operates as a part of the power system. In the scope of the proposed project, an optimization based method for determining magnetically nonlinear characteristics of transformer’s iron core will be developed. The method will be based on data measured on the transformer terminals during normal transient and steady state operation like inrush and operation at no load. The magnetically nonlinear model of the transformer, suitable for the use in the optimization procedure, will be developed together with appropriate numerical methods. The optimization goal will be the best possible agreement between the measured and calculated currents and voltages in the time and frequency domain.

Complete analysis of thermal processes provide numerical methods by using computer software tools. Mathematical description, which gives a coupled problem is almost always non-linear, and it is a combination of time-dependent phenomena. Today, computer systems for solving coupled problems are developed and market accessible, where some commercial programs offer multi-physical options (FLUX2D, FLUX3D). There are also non commercial programs such as, the EleFAnT2d and EleFAnT3d. These packages are based on the finite element method (FEM). FEM is a method of numerical analysis, which presents the method of forming algebraic equations used for approximation of a determined problem.

The subjects of research in the project are:

• transformers, three-phase energy oil and air transformers and

• switchgear (heating due to the working and eddy currents).

The problems of electromagnetic and thermal fields as well as thermal heating of machinery and equipment have been studied. In general, conductors Joule losses occur in all, but these must also take into account the contribution of eddy current. The consequence of excessive losses is increase in temperature to a level that over time leads to failures, changes in the properties of materials, changes in the mechanical arrangement of operation and the like. Re-dimension is absolutely necessary in this case. Each over-dimension affects the total cost of the product, so the calculation of thermal fields is indispensable.

This work deals with the optimal distribution of overhead transmission power line conductors. Positions of individual conductors are determined for single- and double-circuit power lines with bundles of two, three and four conductors. The optimization is performed considering conductor sagging and insulation coordination requirements. The optimization goal is to find such distribution of power line conductors where the tower height is minimal while the emissions of electric and magnetic fields are under prescribed limits right away.

The electricity system is the largest and the most important system for substantial economic activity and society functioning. It must be designed to enable consumers a prolonged economic, reliable and environmentally friendly supply of electric power. Although, all three qualities are very important, the reliability of energy supply is undoubtedly principal. Failure to


supply electric power due to network interruptions may cause great economic disadvantages and impair safety conditions. The question is how much should it be invested into 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.

This work evaluates excessive transmission line losses in the three-phase systems caused by unbalanced and nonlinear loads. In the 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 like orthogonal decompositions of currents in the time or frequency domains can be applied. Using these tools, it is possible to determine current components indispensable for energy transmission and those current components that do not contribute to the energy transmission and cause excessive transmission losses which can be avoided.

In this work, the orthogonal decomposition of three-phase currents in the time domain is used to determine current component 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 generalized power factor in the three-phase system. The generalized


power factor is used to characterize the load unbalance and effects of nonlinear load. Excessive transmission losses in a low voltage distribution line are evaluated by case studies performed for different operating conditions.

The development of power electronics and converter techniques made possible the growing use of permanent magnet motors in modern electric drives. When compared with the other types of electric motors, the permanent magnet motors show superior performances. A crucial part of each permanent magnet 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 the systematic approach to design permanent magnet 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 price will optimally fit the required motor performances, operational characteristics and design.

The research defines, in greater detail, the advantages and drawbacks of possibilities of inclusion of ČHE into the electricity transmission and distribution network from technical aspects for methods of execution:

400 kV overhead line

400 kV underground cable

In the context of the research, other aspects such as implementation, operating reliability, maintenance and life span are considered. By drawing up bases to define the affects on the environment, the developer will collaborate with the experts from the fields of spatial planning and nature, who will be provided by the customer.

The conclusions of individual parts of the research are used for the implementation of the comparison of individual methods of execution, which is the integral part of the research where possible corridors of integration of ČHE Kozjak into the electricity transmission system of the Republic of Slovenia, according to their type (free-space/cable), are taken into account.

In the context of the research, there is a separately handled variation of an 400 kV overhead


line in the existing corridor, south of Maribor, where there are three 110 kV overhead lines today, taking into consideration the cabling of the previous, and separate treatment of the 400 kV cable alignment.

Complete analysis of thermal processes provide numerical methods by using computer software tools. Mathematical description, which gives a coupled problem is almost always non-linear, and is a combination of the time-dependent phenomena. Today, computer systems for solving coupled problems are develop and market accessible, where some commercial programs offer multi-physical options (FLUX2D, FLUX3D), there are also non commercial programs such as, the EleFAnT2d and EleFAnT3d. These packages are based on the finite element method (FEM). FEM is a method of numerical analysis, which presents the method of forming algebraic equations used for approximation of a determined problem.

The subjects of a research in the project are:

• transformers, three-phase energy oil and air transformers and

• switchgear (heating due to the working and eddy currents).

The problems of electromagnetic and thermal fields as well as thermal heating of machinery and equipment have been studied. Generally, conductors Joule losses occur in all, but these must be taken into account as well as the contribution of eddy current. The consequence of excessive losses is increase in temperature to a level that over time leads to failures, changes in the properties of materials, changes in the mechanical arrangement of operation and the like. Re-dimension is absolutely necessary in this case. Each over-dimension affects the total cost of the product, so the calculation of thermal fields is indispensable.

Because of the more expensive materials used at the production of the FI relay, the possible cost reduction is the reduction of the throw out made by the production. To reach the mentioned aim, the exact analysis of the magnetic and mechanical conditions has been made; the concentrated parameters have been assessed and influential factors of the magnetic circle, together with their influence on the relay’s working reliability, have been found out in the scope of the task. Based on the findings about the existent relay type imperfections and demands for the technologically simple production, the new suggestions


for the relay’s 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 to improve 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 energy sources based on fuell cell technology. We develop new converter structures and advanced control approaches based on

The project deals with a) robot systems and control, and b) product modeling and intelligent computing by the methods that enable description of a complete functionality of mechatronic systems due to an interaction between all of them. Computer based engineering methods are developed at the partners and are then composed into 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 the models that are required for many different functions developed on different levels of abstraction so that the 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 the paradigm for improved 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 a vision based control and bilateral teleoperation

The aim of our study is to provide new molecular diagnostic markers and molecular targets for novel drugs design for the better prevention and treatment of complex gastrointestinal diseases. 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 a higher risk for complex gastrointestinal diseases and different individual responses to the 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 the 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 available 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 the disease. We will establish a comprehensive follow-up of 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 the 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

J3-0674 Kvantitativni prikaz perifolikularne vaskularizacije in ožiljenja corpus luteuma pri dominantnem foliklu iz naravnega ciklusa (Quantitative assessment of perifollicular vascularization and vascular network of corpus luteum in dominant follicle from natural cycle)

Leader: Prof. Dr. Veljko Vlaisavljević (UCC Maribor) Participants: Prof. Dr. Damjan Zazula, dr. Boris Cigale, Smiljan Šinjur Project partners: University Clinical Centre Maribor

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

In the study, we will employ echographic monitoring to determine the development of the dominant follicle, its luteinization and the development of corpus luteum. We will monitor endocrinological parameters of their endocrinological activities (levels of estradiol and progesterone in serum) as well as their echographic image. 3D images will include a sample of an ovary with the dominant follicle and surrounding tissue. With a specially developed computer program and equipment, we will observe the progress of neovascularization in perifollicular zone and corpus luteum. We will analyze the images of the area in perifollicular zone and, with the help of power Doppler, measure blood flow in small vessels. These will be quantitatively assessed and demonstrated in 3D. We will observe the changes of corpus luteum development in the natural cycle after spontaneous ovulation and after follicular aspiration due to the ART procedure, which can lead to a damage of a vascular network in the perifollicular zone on account of aspiration and consequently its impaired function.

CS - 14 System Software Laboratory

In 2008, we focused on the recognition of ovarian follicles and vessels modelling. At segmentation part, we improved reliability of the follicle centre detection with new advanced mathematical model. As a part of vessel modelling we developed the procedure for vessel quantification, which enables us the statistical processing. For vessels reconstruction we introduced the algorithm, which is based on minimal spanning trees.


V4-0537 Priprava registra napovedi in pridelkov jabolk in hrušk s pomočjo vizualizacije rodnega volumna dreves (Arrangement of fruit forecast and yield register for apples and pears based on visualisation of tree growing volume)

Leader: Asst. Prof. Dr. Denis Stajnko (Faculty of Agriculture and Life Sciences)

Participants: Prof. Dr. Damjan Zazula, Smiljan Šinjur Project partners: Faculty of Agriculture and Life Sciences


Early harvest forecast is of the utmost importance to the organization of harvesting, preparation of storage space, choice of fruit for longer storage and setting sales prices and routes, especially in the production of apples and pears, since these two types of fruit in Slovenia reach almost 72% of the area planted fruit. In Slovenia, between 1991 and 2001, production forecast was based on Winter also known as Bavendorf method. Since 2002, the production began to be anticipated by a SURS-terminology and the terminology of European fruit organization Prognosfruit. Forecast and actual production differs from each other in different years by 12% or even 55%.

The possibility of improving the predictions and the speed of data collection increases with the use of digital cameras (artificial vision), and visualization of digital images. Processing of images manages to build a reliable algorithms for prediction, based on photographs of monitoring crops, in which the average prediction deviates from the actual yield from -5% to +5%.

The Goal of this project is to create technical, professional and legislative basis for the production of a register of products, based on the actual condition of crops and orchards. We will prepare recommendations to be appropriate for our specific production, environmental, climatic, geographical space and social situation.

Project partners: Faculty of Law, University of Maribor, Faculty of Criminal Justice and Security, University of Maribor, Viris d.o.o.


Duration: Oct. 2006 to Sept. 2008

The project results are elaborated in four different areas: the legislation area, the case law area, the education area and the institutional area. Within the frame of legislation we proposed to harmonize it with the Convention of cyber crime, and in the criminal law the provisions about the confiscation, protection and analysis of digital evidences should be added.

In a wider area of criminal law, we should take care of at least the following: to determine the list of tested forensic tools, which are appropriate for the investigation of digital media, devices and systems. Also a way of keeping this list up to date should be found. The criteria and conditions for forensics experts, which are working on the area of digital forensics, should be determined as well. The advantages and disadvantages of eventual certification process should be thought over, keeping in mind that the experts in the area of digital forensics have to upgrade their knowledge permanently. The inner reconciliation of the whole legislation on the terminological level should be assured.

In the area of case law, the amount and the penetration of digital evidences are forcing to change the law and jurisdiction. If we want to follow the changes, additional highly educated and qualified people will be necessary, as well as new hardware and software at all times. In the case law, the shifts are only possible, based on previously formed and suitable legislation and education system – the suitable approaches on these two areas will be reflected in the case law as positive consequence.

In the education level, Slovenia belongs to the countries, in which the subject “Digital forensics” is not included in the programmes of faculties and institutions, which educate the future public prosecutors and judges. As well as these topics that are not included within the


subjects Crime process law and Criminalistics. This situation creates a serious concern about the future of this area and the changes are urgent. Concerning the future skilled workers, this is the matter of Faculties of Law and Faculties of Computer Science and Informatics. Concerning the education of active jurisdictional workers, we urgently need the national education programme, which will be adapted to function of each competent agency. In the first line, the full informational literacy for jurisdictional workers should be assured and the basic knowledge about the digital forensics and the digital evidences as well. The basic part of the education programme, called “What should the lawyer know about the digital forensics and digital evidences?” should include at least the following contents:

The basics of information science, communications and computer science as basics of working of computers and different digital devices and systems

The introduction to digital forensics

The most frequent forms of criminal offences and other judicial occurrences, which could be proved using digital evidences

The presentation of the most popular and/or reliable forensic tools

The basic procedures about collecting, saving and protecting the digital evidences (confiscation of media, data)

Basics about the analysis of digital evidences

The presentation of digital evidences in the court of justice

The problems of anti-forensics.

On the institutional, level we propose urgent activities about the implementation of digital forensics and digital evidences in the jurisdictional praxis. The question is, who should prepare these activities, in the first line the proposal of quality legal basis, the preparation of suitable education programmes and offering the wider jurisdiction the necessary professional help in connection with state-of-the-art technology. The optimal solution is that those tasks take over one main institution based on the state authorization. It is not important, how this institution is organised and named, but it is important that it is the group of the best professionals from wider area of digital forensics and law. Whilst the performing of digital forensics in the private sector could be (or even have to be) subject to competition rules, it should by no means be permitted to perform the service of digital forensics for the needs of police and jurisdiction.

The research addresses the increasingly urgent issue of use, protection and potential abuse of personal data in modern information society. Personal data is stored in electronic form in increasingly simplified and accessible ways with the goal of improving society's operational efficiency. This trend also significantly exposes personal data and increases the risk of its abuse.

In the project, all the goals were achieved. Feasibility of automated collection of personal information on the web, especially from publicly available databases, has been studied. With specially designed automated tools and some human effort, it is possible to create a full database of land owners and, indirectly, inhabitants of republic of Slovenia. Additional binding of gathered data to other publicly accessible databases, which can be accessed via governmental web portal, represents an additional source of personal data and, consequently, a large potential for their abuse. Due to the delicate nature and possibility of abuse of the developed automated tools, a virtual service has been created that demonstrates abuse possibilities of specialized automated gathering and linking of personal data. The service has been presented to the broader public in the fields of law and informatics.

A survey with the managers of databases has been carried out in order to extract the key points in the life-cycle of gathering, storing and managing of personal data. A special care has been taken to identify the level of data security in publicly accessible information systems, especially those, that manage a huge amount of personal data. The environments, in which these systems are developed, built and tested, have also been covered in the survey. From the results of the survey, recommendations for gathering and managing of personal information have been issued.

We also noticed that the level of awareness of some data managers has risen, and some basic techniques for prevention of automated data gathering have been introduced. The efficiency of these techniques is limited, but it is the first step towards a better security and management of publicly accessible databases on the web.

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 the support for more-control of organizations. They operate via central server at the Ministry of Agriculture, which provides central control.

The EKOFARM3 has been 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 databases have been merged into a single one for all organizations and a unified login has been 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 in 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 independence 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.

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.

BI-CY/08-09-008 Surface Reconstruction from Unorganized Datasets

Leader: Dr. Krista Rizman Žalik (Faculty of Electrical Engineering and Computer Science), Yiorgos Chrysanthou (University of Cyprus, Computer Science Department, Nicosia, Cyprus)

Participants: Prof. Dr. Borut Žalik, Dr. David Podgorelec, Dr. Sebastian Krivograd, Dr. Gregor Klajnšek, Dr. Mirko Zadravec, Vid Domiter, Boštjan Pivec, Denis Špelič, Bojan Rupnik, Blaž Repnik, Denis Obrul

Project partners: University of Cyprus, Computer Science Department, Nicosia, Cyprus

Financed by: Slovenian Research Agency, Government of Cyprus

In this project we deal with surface reconstruction from unorganized data.The cluster creation method for surface reconstruction from a cloud of points is applied as a tool for searching for patterns and organization – data regularity and for the points cloud partitioning. The cluster creation algorithm is based on calculation of dimensions and local densities for each point in the cloud of unorganized points. The obtained triangular mesh is often too detailed. The details are insignificant and often invisible when the surface is rendered. Consequently, the mesh is reasonably simplified.




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: 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

Duration: June 2006 to May 2008

The goal of the project was to create a software system that supports as realistic 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 year 2008 we have successfully finished the project implementation and provided the corresponding documentation.

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

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

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


Duration: Sep. 2005 to Aug. 2008

In this project, we have considered problems arising in facility location analysis, and provided 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 are mainly drawn from the fields of computational geometry, graph algorithms and data structures.

Financed by: ELES d.o.o

Duration: Sep. 2008 to Dec. 2008

The goal of the project was to establish a direct connection with land register database with help of WEB services, and to connect obtained data with already existing solutions. To achieve this goal we have firstly reviewed possibilities of spatial infrastructure interoperability and current state in ELES d.o.o. Taking into account the obtained information and requirements from ELES, we introduced the concept how to receive and then accept the changes in land register. The concept was then implemented as WEB application. It accesses the land register at the Surveying and Mapping Authority of the Republic of Slovenia (GURS) over the HKOM net and stores the received data into both, Oracle Spatial database and the file system.

BI-PT/08-09-008 Razumevanje domensko specifičnih programov (Program Comprehension for Domain-Specific Languages)

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

Participants: Dr. Tomaž Kosar, Dr. Matej Črepinšek, Dr. Damijan Rebernak, Dejan Hrnčič, Marjan Horvat

Financed by: Government of Portugal, Slovenian Research Agency

Program Comprehension is a hard cognitive task that involves the construction of a mental model of the program that tries to reconstruct the thoughts of the first programmer. On the other hand, domain-specific languages are languages tailored to a specific application domain. As such, domain-specific programs should be easier to understand. Unfortunately, these beliefs have not yet been fully validated in practice and research about program comprehension is mainly devoted to general purpose programming languages. Therefore, one of the objectives of the proposed project is to measure how easy is to understand programs written in domain-specific languages and to apply existing program comprehension approaches and techniques to domain-specific languages. The process of re-construction of program mental model can become easier when concrete representations are automatically constructed, which reveals different aspects of its structure and behaviour. So-called program visualizers or program animators are important aids in accomplishing such task. However, such tools are often non-existent in the case of domain-specific languages. Hence, the goal of this project is to automatically construct program comprehension tools for domain-specific languages.

Napredna področja v inženirstvu gramatik (Advanced Topics in Grammar Engineering)


Participants: Dr. Tomaž Kosar, Dr. Matej Črepinšek, Dr. Damijan Rebernak, Dejan Hrnčič, Marjan Horvat

Financed by: Government of France, Slovenian Research Agency


In the realm of software engineering, context-free grammars are of paramount importance for defining the syntactic component of programming languages. Grammars are increasingly being used in various software development scenarios where the need for engineering discipline for grammars (grammarware) has been identified. Moreover, grammars can be found in many applications, such as: information theory, evolutionary computation, neural networks, data mining, bioinformatics, and even in areas outside computer science (e.g., organizational science and mechanical engineering). We called such system grammar-based system whenever the vital component of such system is well structured and expressed with grammar or with sentences produced by this grammar in an explicit or implicit manner. However, developers of grammar-based systems are not language design experts and to develop a quality grammar, which suits their need, is a significant engineering task. The goal of the proposed project is to find grammar patterns in context-free grammars and to establish a library of grammar patterns. With such library of grammar patterns, the task of developing grammars will be much easier for developers of grammar-based systems. The investigation should also lead to identification of problems linked to grammar versioning. Moreover, the objective of the project is to propose new metrics, which better reflect the quality of the grammar. Current grammar metrics are not end-user oriented and evolution of grammar toward better quality is hard to control.

BI-SK/08-09-002 Razvoj programske opreme na osnovi adaptivnosti jezika (Software Evolution by Language Adaptation)


Participants: Dr. Tomaž Kosar, Dr. Matej Črepinšek, Marjan Horvat, Dejan Hrnčič, Assistant Prof. Dr. Boštjan Slivnik (FRI)

Financed by: Government of Slovakia, Slovenian Research Agency

Proposed research is focused on a new approach of the development of software systems through languages that are adaptable to specific domains. The goal is to exploit permanent change as the essential property of a software system that is automatically evolved. Project contributes to the emerging field in software engineering, known as software language engineering, and integrates specification, programming and modeling requirements with runtime events by adaptable domain-specific language. The goal of the project is to investigate software evolution and to propose a possible solution by language adaptation. Computer languages (modeling and programming languages) should provide language constructs that more directly support software evolution.

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 that is related 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 connecting 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

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 at the 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, interactive media publishing companies, Internet-service providers, industry, especially in developing company marketing material and selling products or services on the Internet. In the first years of studies, an 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 so the students can 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 members of the institute in the above-mentioned areas, is, therefore, directly incorporated into the educational process.
