FOREWORD

Comprehension that a contemporary university presents the most productive scientific-research institution, is the basis, around the world, of an exceptional development in all fields of human functioning. It is the same with the scientific research work at the Faculty of Electrical Engineering and Computer Science at the University of Maribot, which is beside the pedagogic activity, a key pillar of its functioning. We are proud that FERI is currently the largest registered research organization in the northeast and presents, with its almost 300 employees and more than 170 researchers, a powerful factors in its environment, especially because we are working and utilizing the latest research equipment. As in every previous year, the resaults of our work, in the research field, in the previous year are presented in this Annual Report. On foundational, applicative and international projects, on various levels, we are especially proud of those projects that are conducted for industrial partners because with such, it is our best way to proove our connectedness with the economy. Year after year, despite a relatively uneasy economic situation, we nourish good traditional relations with the industry and where it is possible, we make it even stronger. I think that FERI is an excellent example of a successful transfer of knowledge from an academic mileu to the industrual one. Of course we should not forget, that the education is the primary mission Of every faculty and we as well educate young experts, engineers, masters and doctors of science. We are pleased and proud that our graduates are known for being diligent, reliable and above all with well rounded education. They are very sought after at the job market and well employed, and many of them founded successful hightech companies. I know that our graduates from new and reorganized study programmes are and will be successful as well. The first generation has in previous year already completed the so-called first cycel of Bologna university and higher education study programmes. A number of young researchers, especially those whose education was financed by the Research Agencs of the Republic of Slovenia and Technological Slovenian Agency, speaks of the faculty's successfulness on the educational-research field. In 2010, there were 51 young researchers of all profiles. There are eight program units that function as part of the faculty, under which they are engaged in a fundamental research. The results of such work are presented in this Annual Report. For the rest of the resaults, it is important to note a large number of publishings in the most regarded scientific journals, and those numbers are increasing, which points out to a quality scientific work. It would give me great joy if you would take time and study our Annual Report of the scientific- research work at the Faculty of Electrical Engineering and Computer Science.

Postgraduate Studies

Postraduate studies are basically aimed at the acquisition of in-depth theoretical and applied knowledge, which enables the prospective graduate to carry out an independent and creative research in various technical sciences. Postgraduate study is directed towards a scientific research work and encompasses an introduction into the research work, development of ability to carry out the research work in the individual field of science or the scientific discipline as well as to study the subjects that deepen and widen the knowledge, necessary for preparation and completion of Master’s thesis, or the PhD dissertation. Available to students during their study are laboratories and computer infrastructure at the Faculty of Electrical Engineering and Computer Science, as well as at the other faculties and public research centers with which the faculty has an appropriate agreement. The research work of the postgraduate students is carried out in the research laboratories, which will be presented in continuation, in greater detail. A research groups are formed for individual research fields, which may also comprise into a laboratory. Post graduate and PhD students are also part of the research groups. For the latter, international connections among research groups are very important since that way the successful international transfer of knowledge into the research achievements is possible. Such are examples when our PhD students carry out part of their doctoral research abroad, and some of them have their co-mentors abroad as well. The basis of academic co-operation is creativity, openness, collegiality, and reciprocity. Because of that, the Faculty of Electrical Engineering and Computer Science regularly hosts foreign undergraduate, graduate and postgraduate students. A new way of organization and carrying out of PhD study enables higher comparison with the universities across the world, as well as an easier student exchange. Second cycle study programme We will begin the second cycle study programme in the 2010/2011 study year. The following second cycle study programmes will be carried out:  Electrical Engineering,  Computer Science and Information Technologies,  Informatics and Technologies of Communication,  Telecommunication,  Media Communications,  Industrial Engineering – option Electrical Engineering,  Mechatronics, and Faculty of Electrical Engineering and Computer Science FW – 9

 Educational Computer Science.

Third cycle study programme In 2009/2010, we had begun to carry out the third cycle study programmes in the following study programmes:  Electrical Engineering,  Computer Science and Information Science, and  Media Communications. The third cycle study lasts three years (six semesters) and has 180 ECTS credit. The credits are in accordance with the Measures for accredited evaluation of the study programmes in accordance to the ECTS. Into the third cycle study programme can enroll those who have completed: a) second cycle study programme, b) university study programme, accepted before June 11. 2004, c) higher education professional study programme (accepted before June 11. 2004) and the specialization study programme (listed candidates must before enrolling complete their student duties up to 35 ECTS from an appropriate second cycle study programme) , d) a vocational study programme, that is developed based on the directives from the EU, or another equal masters study programme, which is equivalent to 300 ECTS credits. Appropriate previous knowledge or completed university or masters (second cycle) study from the field of: - Electrical Engineering from the fields of electrical engineering, telecommunication or mechatronics, - Computer Science from the fields of computer science or informatics, - Media Communications from the fields of media communication, computer science or informatics. Overall number of credits that the student needs to collect in every year is 60. The student must complete, during his/her study, the required subject of Methods of scientific research work and three elective subjects, three seminars, and four individual research works. The last semester is designed to write and defend the PhD dissertation. Postgraduate study, programme accepted before June 11. 2004 For postgraduate education (for programmes accepted before June 11. 2004), there are two study programmes:  Electrical Engineering and FW – 10 Faculty of Electrical Engineering and Computer Science

 Computer Science and Information Science. The last enrolment into the first year was possible in 2008/2009 study year; the last enrolment into the third year was possible in 2010/2011 study year. As part of the postgraduate study, the faculty carries out:  a masters degree programme, which lasts two years ,  a PhD in science programme, which lasts four years.. Requirements for enrolment into the postgraduate study programme are defined in the Statute of the University of Maribor and in every annual public call. Both programmes are carried out the same way for the first two years. Postgraduate student must, in first two years, complete an assigned number of exams and prove his/her research capabilities. If the student completed the duties in the first two years with a high enough grade, he/she can continue the study in the PhD of Science programme, without writing the masters thesis. The third and fourth year of the PhD programme is carried out as an individual research work. A student, who in the first two years of the postgraduate study did not attain high enough grades, must before enrolling into the PhD study defend a masters thesis. The overall number of credits that the student must collect in first two years is 120, out of which 75 from exams, and 45 with reports on individual research work. In the third and fourth year, the student must collect an additional 75 credits, which means to complete three more individual research works. Every completed exam or a public presentation of the research work equals 15 credits. The students must complete their study by defending the master’s thesis or doctoral dissertation until September 30.09. 2016.

PROGRAMME UNITS

Eight programme units exist at the Faculty of Electrical Engineering and Computer Science, which are registered with the Slovenian 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 annualy and a condensed overview for 2010 is collated in the sequel.

P2-0028 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. Group activities have covered a wide area; they have been active in the fields of design, control and supervision of mechatronic systems. Development has also included classic and hybrid solutions with the use of nonlinear algorithms, supervision and event-driven control. The research has also been conducted in power electronics systems and micro-and nano-robotics, and significant results have been achieved in the field of measurement and IT. In the system design, we have introduced advanced operations (HIL and RCP) and besides processor systems increasingly used FPGA circuits. Development of advanced control algorithms is continued towards the development of new approaches, with respect to a higher efficiency and quality of the algorithms. They are based on the nonlinear models for direct use or further development of local linear models. By using the nonlinear multivariate statistical methods, a fault detection and isolation scheme is improved, which enables detection of small process deviations under a close-loop operation. An application for simulating the GMAW process and inverter based welding source has been developed. In the field of AC motors torque control, the discrete controller that operates on the basis of calculation and minimization of Lyapunov functions stability has been applied. Activities have also been carried out in the field of position sensorless AC motors control. In the field of advanced control of mechatronic systems, we have conducted research on haptic interfaces. In order to achieve the high quality remote touching sense with the local haptic interface we have derived the robust control method for the bilateral tele-operation system that is composed of multi DOFs robotic systems with a highly nonlinear structure. Within the work on the development of micro-and nano-robots, the emphasis has been on design and control of such systems. A virtual user interface has been built for remote control of a nano- Faculty of Electrical Engineering and Computer Science FW – 21 robot cell. Neural network has been used to evaluate the inverse dynamic model of nonlinear micro-robot mechanism. In the field of power electronics systems, we have been dealing with the control of converter circuits with a goal to reduce electromagnetic emissions. A system of six converters, which have been controlled from a single location, was built. A 4 kW system has been designed as a micro- grid system, which allows the energy flow from DC and AC sources to different types of loads. Measuring technique is an important module of the mechatronic systems where the electric and nonelectric measurements carry special importance. Group activities have been directed towards the development and improvement of new measurement methods. The research has been directed towards various new algorithms and automated distributed measurements. In the field of IT introduction, new measuring instrumentation and fast measurement methods via the World Wide Web are introduced, the measurements in the field of remote experiments are improved, and the new methods of performing measurements in the area of wide dimensions are researched.

P2-0041 Computer systems, methodologies and intelligent services Programme unit head: Prof. Dr. Damjan Zazula This Programme Unit consists of staff from 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, Computer Technologies, Programming Languages and Computer Architectures, Computer Graphics, Internet Programming and Web Services, Distributed Computing, Geometrical Modelling, Multimedia. For 2010, we have proposed the following scientific research that was successfully completed: simulation of natural growth and modelling of eco-systems, differential evolution, programming and domain specific languages, computer vision with multiple view geometry, multivariate data analysis, algorithms for multimedia and computer geometry, and computerised text analysis. In parallel, the following development has been proposed and completed: countryside overgrowth model; intelligent games, in particular computer chess; domain-specific compilers and grammars; scene reconstruction through the use of web cameras; biomedical imaging analysis; support to geographic information systems, and intelligent e-services. We developed an algorithm that is based on self-adaptive optimisation of the control parameters in dynamic environments, in order to solve multiobjective optimisation problems with differential FW – 22 Faculty of Electrical Engineering and Computer Science evolution. We used it in procedural modelling of trees and simulating the countryside overgrowth. It was also introduced in tuning the chess evaluation function. We investigated the understanding of domain-specific programs, defined new metrics for grammars, and studied the inference on grammars and their run-time evolution. Experimental results suggest that certain metrics are directly related to the size and complexity of the grammar, while other metrics are not. Our CKC algorithm was recognised as the world's most effective decomposition of surface electromyograms. We modelled and analysed in greater detail, the CKC core, i.e. Activity Index. We proved that it can be used as a robust and accurate estimator for the number of sources and the duration of their responses in convolutive mixtures of sparse pulse sources. Together with the Laboratory for Electro-Optical and Sensory Systems, we began to develop an unobtrusive, hypersensitive sensor for human vital signs. The sensor is based on optical fibres and interferometry. So far, we have used it for unobtrusive detection of heart rate, respiration and movement of human body. We dealt with the 3D reconstruction of objects of irregular shapes, such as fruits on the trees. This introduced a new way of finding large sets of high-density correspondence points by using rigid and non-rigid image registration. Multiview geometry was also carried out to monitor the construction sites. We have presented the way to implement homographies with coplanar points. A novel method was designed to approximate the central axis of polygons, whose complexity does not exceed O(n log n) when using constrained Delaunay triangulation. From a cloud of points, we reconstructed a surface and proved that an efficient scanning algorithm can be developed by appropriate control heuristics for the progressive fronts. New functionalities were added into the open-source GeoServer and the web application TerraTrackers for tracking the GPS devices in real time. We improved lossless compression algorithms for voxel data, and studied how to present the space of voxels by an efficient hierarchical structure to support progressive visualization on mobile devices. In addition, we have concentrated on text processing in the Slovenian language. We developed an infrastructure for knowledge extraction and detection of plagiarism at the University of Maribor digital libraries. We also worked on a tool for automatic generation of general-purpose semantic and domain-specific dictionary for the fields of university studies and local communities.

Representation of research areas of the program unit in 2010:  In the field of semantic web, we presented a novel method for data sources integration, within the diagnostic processes. Semantic web technologies have been used, which represent one of the key state-of-the-art software engineering methods. Integration model has also been presented, which enables optimization of the diagnostic process from quality and economic efficiency point of view.  In the field of knowledge management, we have presented a new, intelligent data classification method based on evolutionary construction of the decision rules, which in addition to detecting relevant patterns from data sets, allows domain-based detection of new knowledge. As a novelty in the world of science, the process of machine-based learning is presented, which enables the merging of domain expert knowledge with an automatic induction of rules and subsequently the search for new rules and reliable knowledge.  In the field of IS, we have studied the implications of software frameworks. We discovered that the main determinants of the framework acceptance are perceived useful to the framework and trust in the framework, which is consistent with the requirements for a long-term use of frameworks. Results of the research can form a basis for a number of innovative solutions that can positively influence the development and the use of frameworks, as well as framework based applications; such as a method for improving the acceptance of frameworks, which is designed for developers of frameworks and allows iterative improvement of the frameworks and therefore the improvements in information systems.  In the field of service oriented architecture (SOA) and event-driven architectures (EDA), we studied the complementary of these two established technologies for the development of business solutions. In the research studies, we have identified points of contact between those two technologies. Finally, we proposed the extension of concepts of SOA with EDA in the fields of WSDL and BPEL. The proposed solution allows services to act like event procedures and event users.  In the field of security, we studied protocols for key exchange on the basis of identity. One of the main results of research is an efficient protocol for the exchange of keys, based on identities for two-sided environment using the mating operations, which is based on algorithms for digital signature and meets the necessary safety criteria.  In the field of the IS development quality, we researched the usefulness and acceptance of quality index (QI), which is used to calculate the effort in the project of IS development. QI has been empirically evaluated in research, primarily as a mean to identify interchangeable metrics, which can be used for QI. We have examined ten different metrics in 25 different projects and have discovered that six out of ten metrics converge.  In the field of e-learning and IT acceptance, we investigated the acceptance of e-learning systems. Results of the research represent a modified UTAUT model, extended with the FW – 24 Faculty of Electrical Engineering and Computer Science

factors that significantly affect the perceived usefulness and ease of use of e-learning systems. The research results offer new possibilities for further investigations and improvements in the field of e-learning systems.  In the field of modern IS approaches, we studied software factories. Based on a review of existing evaluation models for projects, developed with software factories, we produced a model that allows the capture and evaluation of selected factors of acquisitions.  In the field of the integration of data sources, we studied the possibilities to introduce ontologies. The existing technologies do not enable dynamic and automated data retrieving, when data sources are realized with technologies that are not directly compatible with ontological presentation of the data. As a possible solution to this problem we presumed, that the semantically labelled services enable automated data retrieving in the course of inquiries.  In the field of embedded systems we implemented the operating system’s co-processor; we studied the mobile computing in a cloud and tested an implementation of neural networks for pattern recognition in FPGA. Simultaneously we researched a novel machine learning model that represents a qualitative jump in pattern recognition. We investigated the user experience design in modern, natural user interfaces, integration of users in designing user experience and interaction design while planning human- computer interaction and communication. All knowledge was effectively used in industrial projects.

Scientific disciplines: informatics, metrics, computer science, systems, and telecommunications. The research work is based on a modern digital signal processing. New algorithms for parameter extraction form Synthetic Aperture Radar images are developed. Algorithms for soilmoisture, salinity of see, target detection, land sliding, and change detection algorithms are investigated. Beside algorithms we are also focused on technological aspects of modern digital signal processing by considering acceleration of algorithm with the use of parallel processing using graphical processors units. These research activities are complimented by research and development of telecommunication algorithms as well as investigation of possibilities of their implementation in micro controllers.

P2-0114 Applied Electromagnetics Programme unit head: Prof. Dr. Mladen Trlep This programme unit consists of staff from Fundamentals and Theory of Electrical Engineering Laboratory, Applied Electromagnetics Laboratory, and Electrical Machines Laboratory. Scientific disciplines: Electrical Engineering, Electromagnetism. Faculty of Electrical Engineering and Computer Science FW – 25

Electromagnetic theory and applications research group is comprised of three professional fields/interests of study, which include magnetic fluids, electromechnical converters and electrical discharges in earth and air. All three fields of study are based on the macroscopic electromagnetic field theory that is mathematically determined with Maxwell equations. In 2010, the magnetic fluids field of study was directed mostly towards the design and building of the measuring system. The 3D geometrical model of the indicator (gauge) was built and further used in numerical analysis of the electromagnetic and thermal field, based on finite element methods. The model represents a very accurate copy of the real measuring system, which has been actually built. During the design of the model, our aim was for measuring system to enable characterization of magnetic fluids according to two procedures. The first one is a calorimetric method that determines magnetic losses in a fluid, based on the temperature gradient. In a second procedure, we determine magnetic losses through measuring of magnetic field. The latter procedure during the characterization of magnetic fluids is not possible to trace in literature, hence we have developed it for the purpose of faster measuring and with a goal to verify results of the measurements. Two measuring sensors have been made in order to conduct the measuring of magnetic fluids properties via method of magnetic field. The first one is used to measure magnetic field strength in a magnetic fluid sample, while the second one measured density of magnetic flux in a sample. Both sensors have been calibrated in the field of magnetic normal before installing them into a measuring system. With a goal to automatically conduct the measurements, a program has been developed in a software LabView. Measurements have already been conducted, on a measuring system, on a numerous samples of magnetic fluid, which are in cooperation with research group, prepared and developed by the Laboratory for inorganic chemistry of the Faculty of chemistry and chemical technology of the University of Maribor, as well as samples that are available on the market. The second field of work of a research group, represents a development in a field of electromechanical converters. We have continued systematically with a development of electro mechanic converters for the use in all types of electric and hybrid vehicles as well as in ships, for Slovenian and foreign companies. Electromechanic converters, which are built in electric cars, hybrid vehicles, electric boats, industrial vehicles (forklift trucks, shipping vehicles) and ultra light electric vehicles (golf carts, scooters, electrical bicycles, pedals) represent a rather specific segment of converters. At the forefront of development, is electrically continuous variable transfer and electrically continuous variable driving system for electric and/or hybrid vehicles. On the basis of the chosen engine topology, the first prototype with two rotors and one water cooling stator, was created in 2010. First measurements of load characteristics and heating in generator mode were conducted in the Laboratory for electrical drives and machines FERI. All measurements were conducted during a locked rotor without a water cooling stator. The results of the measurements confirmed the correct design of the machine in relation to the required characteristics. Modular synchronous machines with powerful permanent magnets mounted on the surface are also often used in electric vehicles. Weakness of a such machine configuration during the higher speed of rotation, presents, above all, eddy current losses in permanent magnets. A program for calculation FW – 26 Faculty of Electrical Engineering and Computer Science of those losses has been developed in a previous year, for the purpose of a more precise analysis of these circumstances. The third area of the program is focused on the research of a concluding process, which begins with atmospheric discharge in the form of a lightning, partial discharges in air and ends with discharge in the earth in the form of an electric current. In 2010, we have built-upon and expanded the analysis of widening a leading channel of discharge depending on alternating electric field strength in the background, from diameter and segment length of a leading channel as well as from variable conditions to divide the conductor towards the leading channel formation and spreading, respectively the extinguishment of the side channel. Additionally analyzed were also influences of geometry of the electrodes, reciprocal distances in the experimental model and triggering voltage onto the process of discharge. The work has also been continued on fulfilling and developing of an experimental and numerical model electric spark apparatus, since it is important for the process study and circumstances during discharge and evaluation of a developed numerical model. We have continued with a development of program solution in the area of discharge process in the earth in the form of an electric current, as final consequences of a lightning into an object. The development of program solution has been directed in two directions: considering contribution of field current in the earth and inclusion of process of ionization in the earth. Both need to be taken into consideration during fast changes of the initial current or voltage, which is the case for atmospheric discharges in the earth. As part of this work, a research has also been conducted in the field of re-evaluation of influences of electromagnetic field on people and the environment. The results of the research work of this research group have been presented at a numerous national and international conferences as well as published in journal publications.

P2-0115 Control of electromechanical systems Programme unit head: Prof. Dr. Drago Dolinar This programme unit consists of staff from Electromechanical Systems Control Laboratory and Power Engineering Laboratory. Scientific disciplines: Engineering, Electrical Engineering, Electromechanical Devices Research programme »Control of Electromechanical Systems« consists of two main areas; design and control of electromechanical systems and devices, and electric power system (EPS) research, design and control. Both areas are closely related since individual EPS subsystems are made up of different electric devices. The research program is based on the finding, that the structure of existing devices and control systems can be improved in the manner of increasing power efficiency according to the amount of the input material. Because of the dynamic nature of individual elements and the overall system, these improvements can be made only through the use of a dynamic approach for design and analysis of electric devices and for the control system design. Research programme represents continuation of our work from the past period for almost Faculty of Electrical Engineering and Computer Science FW – 27 all areas, whereas mostly those topics which have been stimulated by our partners from the industry are included. Within the first area, our programme unit is concerned with the dynamic modeling of electromechanical devices and complex technical systems. Here, modern numerical techniques, which have been used mostly by the design and development engineers, are employed to a maximum possible degree. In the field of control we are going to continue our work on the design of highly efficient alternating current drives. In cooperation with the Slovenian company we are going to continue with the design and control of systems for a resistance spot welding (RSW). In the past period, new control system for RSW was already developed which has significantly improved its operation properties, whereas the competitive position on the marked was enhanced. In the current period, we are working on the optimization of the RSW design and the additional improvements in the control. Within the second area, we will continue on the dynamic modeling of EPS, control and protection. The work is also proceeding in the fields of design, development, and testing of new EPS elements as well as electric networks. In design procedures, such numerical optimization methods are used, which enable the design according to selected objective functions, whereas all experimental analyses and the development of new measurement procedures are performed in our own high-voltage/high-current laboratory. In the past research period, we have developed analytical and numerical procedures for physically correct evaluation of the supply network quality and disturbances. Furthermore, we will continue to work on the development of the compensation devices with the unity power factor. We are also planning to analyze the influence of different alternative ways for electric energy production on the improvement of EPS operation properties.

P2-0368 Optical sensors and advanced interactive interfaces Research unit head: Prof. Dr. Denis Đonlagić The research unit consists of the staff from three laboratories at the Faculty of Electrical Engineering and Computer Science in Maribor. They are: Electro-Optics and Sensory Systems Laboratory, System and Control Laboratory and Digital and Information Systems Laboratory. Scientific disciplines: metrics, sensors and gathering of data, electro-optics, telecommunication, computer structures, systems and networks - hardware. The programme includes fundamental and applicative research on the field of optical fibre sensors and interactive interfaces. The main research activity on the field of optical fibre sensors considers the research and the development of the technology for surface micro-processing of the optical fibre nib, which is based on selective etching of the silicone glass. The previously mentioned is achieved when dopants are introduced during the manufacturing process. The process of micro structuring on the optical fibre nib includes the making of the optical fibre, the etching of the fibre and possible welding of the etched structures into more complex systems respectively micro photon devices. Based on the technology of the selective etching, in 2010 the different dopants, which affect the selective etching of the silicone glass, were being considered. We have concluded that the introduction of the P2O5 into the optical fibre has accelerated the fibre etching that FW – 28 Faculty of Electrical Engineering and Computer Science enables more efficient making of micro structures on the fibre nib. A few practical solutions have been conducted on the field of optoelectronics signal processing. These practical solutions enable economically efficient addressing to Bragg cells, which are one of the most common optical sensor widely used. The research programme includes the development of the interactive user interfaces. Therefore, the product called 'the transparent internet video of the sign language' has been successfully developed, which represents an innovation on the field of informing the deaf and hard of hearing.

101-MCT Modern Control Theory Leader: Assoc. Prof. Dr. Rajko Svečko Participants: Amor Chowdhury, Andrej Sarjaš, Zdenko Mezgec, Andrej Knuplež, Nikolaj Semenič, Dragan Kusić Controller design problems were originally formulated in the frequency domain. The main tools, used during the early phases of research for this class of problems, have been an operator and approximation theory, spectral factorization, and (Youla) parametrization, leading initially to a 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 for 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 minimal optimization problem, and is therefore a zero-sum game, where the controller can be viewed as a minimizing player and disturbance and 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 and 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.

ERA 115/01 Online Presence for Learning – OP4L Leader: Faculty of Organizational Sciences Belgrade, Serbia Participants: Assoc. Prof. Dr. Matjaž Debevc Project partners: Henri Poincare University, France; Mediterranean University, Montenegro; Salzburg Research Forschungsgesellschaft m.b.H, Austria; University of Kragujevac, Technical Faculty Čačak, Serbia; University SS. Cyril and Methodius Skopje, Macedonia

Financed by: European Commission, SEE-ERA.NET PLUS

Duration: 1.10. 2010 to 30.9.2012

The main objective of this project is to provide a support for advanced, context-aware Learning Process Management (LPM) within Personal Learning Environments (PLEs) as the increasingly important new paradigm in online education. Being rooted in modern pedagogical theories, PLEs follow learner-centric approach and grant learners with the ownership and full control over their learning processes. They also foster learners’ active involvement in the learning process. However, to fully leverage the potentials of PLEs, learners need adequate support, primarily in the form of recommendation and feedback provision services. Accordingly, by relying upon the results of previous EU-funded projects, we will develop different kinds of services that provide learners with high-quality recommendation regarding the learning activities to be taken, the learning content to be used, and/or who can be contacted for collaboration and/or help provision. All the recommendations will be based on the learner’s current learning context and the state of online presence of members of his/her social graph (i.e., network of online connections). The project will take an innovative technological approach – it will offer new ways of combining Social Web presence data and Semantic Web technologies to provide advanced support for managing online learning resources and processes within PLEs. Here, the role of Semantic Web technologies is to advance the-state-of-the-art in collaborative learning on the Social Web and to meaningfully interrelate existing and/or discover new knowledge over the learner processes (relationships, resources). Additionally, a strong innovation potential of this proposal can be seen in the novel interactive and adaptive support for both learning resources and processes. As the proof of concept, the project will extend an existing semantically-enabled PLE with

AU – 6 Systems and Control Laboratory

new services to support context-aware LPM, while fully respecting the learners’ expressions of online presence.

The project idea is to unite efforts of Ukrainian universities and the Ministry of Education and Science of Ukraine in order to promote realization of public policy in the field of internationalization. It is a good platform for a new qualitative leap and correspondence to the European strategy of Internationalization and Charter on Lifelong Learning. The first objective will allow to give the system character to the internationalization processes at universities, on the basis of common commitment to quality and IT usage. The second objective is aimed at the creation of international open virtual platform on the basis of WEB 2.0 technology for cross-cultural communications in academic society and for skills development in an international project cross-cultural on-line teamwork. With the help of the third objective we plan to enhance the international communications of teachers and students in the training process while using e-tools of internationalization in pilot courses. In the framework of project consortium, we plan to create International Platform for intercultural communication and to develop/modernize a number of course programs.

2008-1-FI1-LEO05- LEONARDO DA VINCI: DEAFVOC 2 − Transfer of Curricula for 00454 Vocational Language Education of the Deaf in Europe Leader: Annemari Laurento, The Finnish association of the Deaf Participants: Assoc. Prof. Dr. Matjaž Debevc, Primož Kosec Project partners: Irish Deaf Society, University of Klagenfurt, Opetushallitus Finland, FERI UM

Financed by: European Union, UM-FERI

Duration: 1.10.2008 to 30.9.2010

The Deaf belong to a European minority which has to fight for the right of 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 in 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 that the main target group (teachers and students) is quite small in each country, the 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 analyzed 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 teachers. This ensures participation of the end-users in the project. The project aims to have 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) which is educational authority with international contacts and grass-root level communication with vocational institutes. FNBE was responsible for the curriculum “Sign Language as a Mother Tongue” in the previous DEAFVOC project.

Duration: 11.3.2009 to 10.9.2010

When a number of disabled people who decide to study increases, the improvement of accessibility of faculty and architectural institutions of higher education increases as well. Much less is done to fix the information and communication barriers, which largely hinder on the process of study and can be inclusive of the methods of study and teaching of reduced or eliminated. The project aims to remove barriers that arise in the process of teaching / learning and thus improve the opportunities for successful studies of students with disabilities and 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, higher education institutions and students to people with disabilities. Project results will contribute to greater awareness on the specific needs of students with disabilities, the obstacles faced in the preparation of strategies to overcome these obstacles. Personnel will provide the knowledge and teaching skills as to how 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 is equivalent to other disabled students. Today, in practice, it happens that the disabled students are not required to perform certain obligations, because the staff is not aware of the possible adjustment of devices, etc. That would allow a student the equivalent knowledge acquisition and provision of study commitments. The project has been carried out was 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 colleges that participate in the project. We believe that we will

Systems and Control Laboratory AU – 9

obtain the project results and transfer them 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 secondary education in lifelong learning.

Duration: 1.5.2009 to 30.4.2012

In 2010, we are focused on developing the simulation model of Gas Metal Arc Welding (GMAW) process, together with the simulation models of inverter based power machines. The GMAW process is considered as an electrical circuit and the mathematical model and is based on physical descriptions of several parts of GMAW process, as are the electric circuit of power supply, the arc dynamics, and the electrode melting process. Next, the dynamic behaviour of full-bridge DC-DC converter is described and suitable discrete PI controller for welding current feedback control is proposed. Both models, the GMAW model and the inverter power supply model, are combined into simulation model of the GMAW process application, together with the inverter based welding machine. Presented simulations are

Duration: 1.4.2009 to 31.3.2012

In 2010, the project's second phase activities have started. Upon initial analysis and definitions made in the first phase, model of furnace elements has been obtained and simulated. Project partners were involved in different tasks of modelling, where partner FERI modelled sensors and actuators for furnace control. Thermo couples, ventilators, and heaters were connected to general model of industrial furnace developed in COMSOL. In parallel, models in Matlab were also tested. In the next phases, advanced control algorithms were developed independently (partners), where upon local furnace models control parameters for improved furnace operation can be obtained. In this way the development of furnace can run in parallel to the control design stage which enables quicker testing phases and time-to- market with products. The model of the furnace was validated on the industrial furnace UNIOR. In the next phase, implementation and testing of advanced control algorithms onto the industrial furnace will begin.

J2-3623 Special optical fibers for use in fiber optic sensor systems Leader: Asst. Prof. Dr. Edvard Cibula, Borut Lenardič, Simon Pevec, Borut Preložnik, Aleš Trkov Participants: ARRS Project partners: Asst. Prof. Dr. Edvard Cibula, Borut Lenardič, Simon Pevec, Borut Preložnik, Aleš Trkov

Duration: 1.5.2010 to 30.4.2013

In the context of the project there is an ongoing research of optical fibers with different dopants within a pure silica glass (SiO2), and at the same time there is also an ongoing research of the field for their usage in optical sensor systems, and possibilities for signal processing. Dopants research is conducted with cooperation from the Optacore d.o.o. company that manufactures optical fibers. Different dopants cause optical fibers to have different properties. Therefore, there are ongoing researches in the laboratory about the possibilities of use of different optical fibers for manufacturing optical sensors. Signal processing is a special case in the use of fiber optic sensors, which is still quite complex and therefore expensive, which prevents such sensors to become widely used. For that purpose there is a research for different possibilities for signal processing of optical sensors that simplify such systems without the loss of accuracy and resolution of the measured parameter, wherein signal processor is still cost effective.

In the context of the project, there is a development of magnetostrictive fiber optic sensors for use in extreme environments, such as oil refinery, mils, pharmaceutical and chemical industry, among many others. Primary goal is development, and construction of magnetostrictive optical fiber which will have magnetostrictive properties achieved by proper dopants in structure of pure silica (SiO2) of optical fiber.

Project includes development of micro-optic sensors for pressure, which is based on mechanical and chemical treatment with devices developed in LEOSS. The base of a sensor is micro-membrane from pure silica (SiO2), mounted on the tip of optical fiber, so that the whole structure does not exceed 125 μm. Because an entire sensor is made from pure silica, such sensor provides high chemical and electromagnetic immunity and durability at high temperatures.

The research takes place in direction of improving membrane and treatment of optical fiber. For that purpose, different devices for micro-machining of optical fiber and membrane are still developing and improving, and at same time different dopants within fiber, which help with

chemical treatment of fiber, are under study.

Industrial projects

Temperature measuring in transformer systems (ITRAN project) Leader: Prof. Ddr. Denis Đonlagić Participants: Matej Njegovec, Asst. Prof. Dr. Edvard Cibula Project partners: Senčar d.o.o.

There is an increasing need in transformer systems to measure temperature within transformer coils and transformer oil for timely detection of defects or overloads. Such environment is highly electromagnetically distorted; hence standard temperature sensors are not appropriate. In such case, it is appropriate to use all-fiber optical temperature sensors, because of their immunity to electromagnetic disturbances and small dimensions. A development of signal processor, which is based on reading the temperature from spectrum reflected from optical sensor is part of the project and at the same time is constructed from standard electro-optic components and is also cost effective. Signal processor is compatible with sensors based in all-fiber Fabry-Perot interferometer, which is made in laboratory, as well as with commercially available fiber Bragg gratings. Signal processor can determine spectral properties of optical sensor with resolution of 1 pm, which corresponds to 0.1 °C, and can read up to 45 samples per second. Different methods of signal processing will be researched in the future and at the same time it is necessary to extend a signal processor in such way so it will acquire several sensors at the same time and that will be compatible with other devices in system for control of transformer systems.

L2-9304 Integrated smart measurement system for acquisition and evaluation of sensor’s signals and automatic calibration of the measurement system Leader: Andrej Vodopivec (Integrirani in diskretni sistemi, d. o. o.)

Sine/cosine sensor is one of the key elements in the linear and rotary encoders. These encoders provide accurate lateral or angle position. In the context of this project, the goal of our research group is to develop the automatic phase shift compensation system (phase corrector). Particularly, the system has to detect very small additional phase shift between the sine and cosine signal in the range of ±10 and then correct the phase. In the previous version the 8-bit D/A converter and external capacitor was needed. The new improved version is completely digital and without the D/A converter and external capacitor. For these reasons, the phase corrector is also completely able to integrate. The new concept is based on few counters that enable averaging the measurement of phase angle. In the average results the random errors can be almost completely eliminated. The accuracy of detecting the additional phase angle depends on the frequency of the clock, the number of repetitions of the measurement and partly on the comparator's properties. 1MHz clock ensures the Electronic Systems Laboratory EL – 11

uncertainty of 0.1.

 0796-005 Applicative power engineering  0796-006 Laboratory for electrical machines  0796-007 Laboratory for control of electromechanic systems  0796-011 Laboratory for power engineering

In the meantime when the first group is mainly involved in research in the field of power engineering devices, the second works in the fiield of electrical machines, the third in the field of automatization in power engineering, and the fourth one in the area of manufacturing, transfer and distribution of electric energy. It is important for the first group researches and develops methods for calculation of electrical potential fields as well as it mainly researches power engineering devices. The second group covers construction and testing of electrical machines. The third field introduces contemporary processes of controlling systems in power engineering. As part of the fourth group, the research is directed mainly towards optimization processes, reliability and quality of electrical energy as well as testing of electrical equipment.

Institute of Power Engineering PE – 2

Due to easier solving of complex colutions, the researchers from out institute are joined into two program units:

 P2-0114 Applicative power engineering  P2-0115 Controlling of electromechanical systems

Programe unit of Applicative power engineering covers the field of numerical problem solving of electromagnetic field with an emphasis on electromagnetic converters, caterization and modeling of magnetic materials, earthing systems, discharges in air as well as inverted problems. The programe unit is made out of nine researches from FERI, who are actively involved in the pedagogic process, as part of the programe unit (PU), which is financed by the SRA with 2,4 FTE, for the foundational research work. This is upgraded with applicative projects for the industry, with submitted slovenian and european patents, with young researchers mentorships and international scientific collaboration as well as with collaboration in international conference committees. The PU intensivelly publishes its work and in the period of 2008-2009, it has published 27 original scientific articles, 16 of which have been published in journals with impact factor. In the last financial period (2004-2008) it has published 92 original scientific articles, out of which 57 were in journals with an impact factor.

Developing potential of the Controlling of electromechanical systems program unit is vast, and is beside seven internal researchers – doctors, also made up of one external evaluator – doctor from the Indramat elektromotorji d.o.o. company. The RU, according to evidence from the SICRIS database, in the period of 2008-2009, beside 50 publishings in journals with JCR through program financig by SRA with 2,4 FTE, has yearly realized around 14 more projects FTE, which were financed by non-budget funds from industry companies. Great developing potential is confirmed by a number of educated researchers – Masters (12) and doctors (4), the quality and innovativity is also evident from prestigous international awards received as well as continual increase in granted and applied patents.

Members of the programe unit were in period between 2004-2009, with its knowledge and experience, participated in a number of international projects such as: Eureka-Distribution Network Automation System (DINAS) project; Quality of medium voltage composite insulators (Domitran CRO project); project with the Northestern University Boston, USA: Nonlinear Torque Control of Induction Machines; Dissemination of energy efficient electric and electronic equipment (EEE) in European universities; The Virtual Balkan Power Center for Advance of Renewable Energy Sources; Impact of disturbances; Solar power plant (sončna elektrarna), VBPC-RE, 6. okv. prog. etc. For their scientific work, they have recieved international awards such as: IEEE The Industrial and Commercial Power Systems Department of the IEEE Industrial Applications Society, 2008 Committee Prize Award of the Power Systems Engineering Committee to B.

Financed by: Stoja d.o.o.

Duration: 1.3.2010 to 30.9.2010

As are the client requirements for this project, we are looking for an optimum variant of two different size motors with the above data to drive an electric car. As a starting point, the lamination IEC 132 from Kienle+Spiess has been used, with different lengths of stator packets. The goal has been to maximize the engine power from batteries through a DC / AC inverter. We varied the winding of the motor to adapt it to the appropriate voltage supply. In the lab for electrical machines different load points have been tested with samples of water cooled motors designed to power an electric car.

Duration: 15.4.2010 to 31.10.2010

Due to noise problems, in the above-cited Ex electric motors, which have received complaints by Bartec customers,, we analyzed the frequency spectrum of a few 4 pole three-phase motors. With a computer simulation and numerical field calculations, the harmonic spectrum of the air-gap magnetic field has been assessed and determined which combination of stator and rotor slots would have the lowest noise level and still correspond to IEC standards. As a result of this simulation the Bartec has produced new motors which have an even lower noise levels than the recommended maximum allowed value, which now meets, far better, customer demands.

Can energy reservoirs act as pumping hydro plants in electric power network? Renewable energy sources (such as wind and sun) are unstable, almost unreliable source of electric energy and the emphasis is on energy. Supply outages in electric power network are usually due to lack of power. Energy reservoirs are those devices that enable unstable energy sources to be comparable with classic transformers. Network is at the moment the most inexpensive reservoir, but this also means that the number, respectively the size of renewable energy sources, connected to the grid, is limited. The intended means of the study are to research which actual energy reservoirs are available, what are their efficiencies and prices. Energy supply from reservoirs can be momentary and they can be dispersed throughout the grid. Economical justification can be determined from the price for deviations. With prices of fossil fuels increasing more and more (oil price has increased in last seven years by factor ten) and with low prices of electric energy (increase in last seven years by factor two) large increase of electric energy prices can be expected in near future. Sun shines at daytime, when also energy consumption is high, but on the other hand constant wind is usually at night-time even stronger as at the daytime. When is energy storage economical with wind power plant? What is the difference between low (night-time) and high (daytime) electric energy price that makes energy reservoir economically just? System solution must also be prepared to be able to sell the energy from the reservoir.

From their size to the variety of use in technical fields, electricity systems most likely represent the highest technical achievement in the human history. 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 unpredictable load change, short circuits, endurance, isolation materials, unpredictable weather changes (ice, wind, etc.) are only a few of the unpredictable factors, which usually occur by chance. There is every prospect that decisions which have been 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 different results are obtained. 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 i.e. whether an additional line from the same is created or if different transformer station is legitimate. It may be a

criterion to cover the expenses – company’s energy supply or a consumer who finds the extra supply unnecessary.

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

Development of the mathematical model of HE chain and analysis of generation planning and power at DEM and SENG Leader: Assoc. Prof. Dr. Boštjan Polajžer Participants: Asst. Prof. Dr. Jožef Ritonja, Robert Brezovnik, Prof. Dr. Bojan Grčar, Jelena Popović, BSc, Zlatko Strelec

Financed by: Holding Slovenske elektrarne d.o.o.

Duration: 1.12.2010 to 30.6.2011

In the first portion of this project, a single aggregate model of DEM has been developed and built-upon by considering pumped storage power plant Kozjak, with which the model core of HE chain has slightly changed. The core of a single aggregate model of HE chain has been adjusted to a universal type of model use, with which it is possible to change all important model parameters, which enable client realization of rather varied analyses of HE chain functioning. Due to a development of single aggregate models of HE chain in a programe tool Matlab, which due to a beforehand defined functions that enable quicker development and model analysys, the final product of a single aggregate model of HE chain was transformed into object oriented free-of-charge programe language C#. With such, the expenses of the client’s study for the purchase of commercial programe Matlab have been cancelled as well as for an adequate cadre education and for the mentioned programe. User-friendly graphic interface has been added to a single aggregate HE chain. The interface also has all the

Laboratory for Electromechanical Systems Control PE – 22

necessary protecting and warnings that disable the user from a incorrect use of programs and upon the incorrect entry of data, they warn and lead the user to the most quicker to solve the problem. This type enables simple and fast use of programe. All possible graphic views of all important variables, which enable quick and simple way to overview the calculation results, have been added to the graphic interface. Tabulated copies of important times of variables have been also added, which enables direct transfer of tabular values into a programe tool Excel, which is made possible by the client of the study and it enables further analysys and storage of results. For the realized programe of a single aggregate model of HE chain, the most important parts of a single aggregate chain model have been described, which are needed for a good knowledge of model functioning and its use. The necessary instructions for the program use have been written, along with practical examples. For an unresolved point of previous study (late due to an irresponsibility of other contractors) new statistical pool characteristics have been calculated. In such process, the actual forms of Drava river chanels were required. All necessary calculations and analyses of changes in volume and area of water have had to be made, in relation to the water level in the pool. Polynoms of useful volumes of water, in the pool, have been determined as well as dependency polynoms of the water level from the useful water volume in the pool, which are used in a single aggregate chain models of DHE.

Primary regulation of frequency of Slovenian power engineering system – 1st- part Leader: Asst. Prof. Dr. Jožef Ritonja Participants Assoc. Prof. Dr. Boštjan Polajžer, Robert Brezovnik, Prof. Dr. Bojan Grčar, Jelena Popović, BSc, Zlatko Strelec

Financed by: Elektro-Slovenija d.o.o.

Duration: 9.5.2010 to 30. 3. 2011

The study has been involved in questions of primary regulation in the Slovenian power engineering system. According to realization and operation analysis of turbine regulators and after a discussion with the power plant managers, a methodology that determines actual conditions during the conducting of primary regulation of individual aggregates has been planned. Covered methodology, besides analysis of block diagrams of turbine regulators encompasses the analysis of responses of aggregates, chain power plants and regulation region, obtained from measuring systems such as WAMS and SCADA. For overseeing For supervision of collaboration of aggregates during the implementation of primary regulation, a number of criteria have been set, which are based on the change of active power, change of energy and incline of P-f characteristic. Besides such, a new critera has been introduced to evaluate the quality of implementation of primary regulation of regulative region, which without a doubt

PE – 23 Laboratory for Electromechanical Systems Control

determines a portion of contribution of power between the individual decrease of frequency. Evaluation of methodology has been conducted through a study of examples based on the measurements from WAMS and SCADA systems, with a report analysis »Regular Report of the Performance of the Primary and Secondary Load – Frequency Control« and through collecting of data on turbine regulators. Programe tool has been created for supervision of a dynamic aggregate response at primary regulation of frequency (ELES_PrimReg), which is intended for analysis of time variables of amounts of Slovenian power grid in relation to a supervision over a dynamic response of aggregates of primary regulation frequency in a unreal time. Since the programe does not function in real time, it opens in relation to obtained information, which are stored from the measuring systems WAMS and SCADA.

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, simulated controllers and mechanisms. Simulations deal with virtual and real systems and processes. For this reason, we also investigate the nonlinear and robust control.

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 that are based on fuell cell technology. We develop new converter structures and advanced control approaches, based on digitalization of the control algorithm by different microcontrollers and different FPGA

Institute of Robotics RO – 2 circuits. The laboratory is well connected with very important industrial companies in Slovenia, such as Iskra Avtoelektrika, DOMEL, TECES ... and European companies such as Daimler- Stuttgart, Fiat-Torino and STM-Catania.

The Institute of Robotics co-operates with many universities abroad. In the Socrates-Erasmus project we co-operate with Universidade do Minho - Portugal, Technische Universität Braunschweig - Germany, Technische Universität Wien - Austria, Universitat Politechnica de Catalunya - Spain, Universitat Rovira i Virgili - Spain, Loughborough University - United Kingdom. In the CEEPUS programme we co-operate with Technical University of Timisoara - Romania, Budapest University of Technology and Economics - Hungary, Cracow University of Technology - Poland, Vienna University of Technology - Austria and Technical University of Košice - Slovak Republic.

Duration: May 2009 to April 2012

As the main research hypothesis the digitization of the current loop that will enable the implementation of current modulator was set. Current modulator will replace the classical current control scheme, known as a current regulator with a PWM unit. In the first project year, the structure of DC-DC converter was chosen and the measurement chain made of u/f converter was proposed. All developed electronic components were tested. A protocol for testing was defined where the mode for measurement, test signals and dynamic requirements were considered. Only one leg of the multiphase system was tested. For the purpose of these tasks the simulation models of converters were built in Matlab/Simulink software environment. The operation of single-phase, two phase and four-phase converters in both directions, at different working points and under different load conditions were tested. The model of the measurement chain that consists of the current (or voltage) sensor, u/f converter and properly configured digital counter has been developed. A mathematical description of these processes was done and on its basis the prototype of the measurement chain was experimentally verified.

The digitization of current loop, which will enable the implementation of current modulator, was set as the main research hypothesis. Current modulator will replace the classical current control scheme, applied as a current controller with a PWM unit. During the last year we designed the structure of DC-DC converter and the proposed measurement chain using u/f converter. All developed electronic components were tested. For the purpose of testing, we prepared a protocol where we prescribed a means of measurement, test signals and dynamic requirements, which were tested on a laboratory model of the converter, produced for this purpose. A single branch of the multiphase system was tested. For the purposes of these tasks we have built simulation models of converters in the Matlab Simulink software. We tested the operation of a single-phase, two phase and four-phase converter in both directions. Also, other designs such as one-and two-phase structure operating at different working points and under different load conditions were tested. Additionally, we developed a model of the measurement chain that consists of the current (or voltage) sensor, u/f converter and properly configured digital counter. A mathematical description of these processes was made and on the basis of these results an experimental prototype of the measurement chain has been produced.

With the aim to improve and ease the implementation of developed methodology for industry, the motion control method in continuous sliding mode regime is adapted. The method is already implemented on an industrial direct drive robot and some other mechatronic devices. In a control fuzzy logic system has also been integrated, therefore the final method is also suitable for control of group of mechanisms with nonlinear dynamics, where most of the mechatronic devices belong. System has been handled as a whole also from a viewpoint of

Current research projects

Research and developement projects

Development of a learning application of interventions related to fire Leader: Prof. Dr. Nikola Guid Participants: Asst. Prof. Dr. Simon Kolmanič, Andrej Nerat Financed by: Ministry of Defence, Administration for Civil Protection and Disaster Relief

Duration: 21.6.2010 to 21.5.2011

In this project, we have developed a learning application SIN - Intervention Simulator to teach correct procedures to intervene in fires. The application SIN enables fast and easy building of teaching scenarios that involve fire. The scenarios are then modified on the basis of a discussion between the lecturer and participants where the lecturer directs participants towards better decisions. To receive a better attention from the audience in the given scenarios, the environment is enclosed, which participants know from their life. This can be done through the use of a photo as the background. In this photography the scenario building components are added involving "Chroma key" technique. These building components can be static or dynamic. Static components are 3D objects of interventionists and their technique and buildings or vehicles that are involved in the accident. The dynamic building components are flames and smoke which change their form in time. To generate realistic smoke images we have modified the well-known methods for spatial modelling of clouds, which can be used to generate smoke in 3D space. Instead of implicit spheres we have used implicit circles whose structure has been defined by an array of pre-calculated 3D noise. The lecturer can control their structure and form a flame and smoke by the minimal number of parameters. All Computer Graphics and Artificial Intelligence Laboratory CS – 6

components can be added or removed at any time. The same is also true for their positions and sizes that can be changed at will. Since the use of this tool does not require additional training, it can also be used to test students’ knowledge, where an instructor prepares the script, which students have to resolve. The application is accompanied by a library of objects that appear either by accident or at the rescue side.

RESEARCH PROJECTS

Current research projects

Basic research project

J3-0674 Quantitative monitoring of perifollicular vascularisation and the development of corpus luteum during a natural cycle in the dominant follicle (Kvantitativni prikaz perifolikularne vaskularizacije in ožiljenja corpus luteuma pri dominantnem foliklu iz naravnega ciklusa) Leader: Prof. Dr. Veljko Vlaisavljević (UCC Maribor) Participants: Prof. Dr. Damjan Zazula, Asst. Prof. Dr. Boris Cigale, Smiljan Šinjur, Vojko Glaser, MSc Project partner: University Clinical Centre Maribor

We studied echographic ovarian recordings to determine the development of the dominant follicle, its luteinization and corpus luteum. In 2010, the main goal of our research was to complete an automated ultrasound volume processing that minimally depends on interventions of medical personnel. Developed software and hardware enable user to export ultrasound volumes from the ultrasound machine to the external flash drive. The developed software imports ultrasound volumes and analyses them in the external computer. All results are stored into a database for further statistical analysis by medical specialists. Our research confirmed that it was possible to automatically detect the position, volume and diameter of vessels that surround the follicle in the ultrasound volume. We showed that the System Software Laboratory CS – 16

implementation of wavelet-based detection of follicles is highly noise resistant and, consequently, leads to reliable follicle detection. Our mathematical model that uses 3D wavelets was developed and improved during the research. Perifollicular vascularisation was located and estimated statistically after the position of a follicle was found. Since the resolution of vascularisation as detected by power Doppler volumes is low, we paid a lot more attention to a post-processing algorithm that reconstructs blood vessels by using minimal spanning trees. We also implemented the method for elastic ultrasound volumes registration. Thus, it has been possible to monitor the growth of follicles over a period of a few days.

International projects

iMOVE Extraction of information on muscle control during movements Leader: Prof. Dr. Damjan Zazula Participant: Asst. Prof. Dr. Aleš Holobar Project partners: Politecnico di Torino, Italy, Aalborg University, Denmark, University of Jyväskylä, Finland

Financed by: The European Commission, 7th Framework Programme

The main objective of the iMOVE project is to design and implement automated signal processing techniques capable of extracting the information about the individual motor units from the dynamic surface electromyograms (EMG), recorded during controlled dynamic contractions of skeletal muscles. The main objective is to study the feasibility, efficiency and repeatability of information extraction during movements, and to define the recommendations for sensors, sensor placement and signal processing in dynamic conditions. Possible collateral applications of the proposed project include objective assessment of effectiveness of rehabilitation and training of athletes, prevention of work-related neuromuscular disorders and diseases, and monitoring of the musculoskeletal deterioration in the microgravity environment. In the first 23 months of the project, two decomposition techniques were developed. They are both based on previously published Convolution Kernel Compensation (CKC) technique [A. Holobar, D. Zazula, “Multichannel blind source separation using convolution kernel compensation,” IEEE trans. signal process, 2007, 55(9), pp. 4487-4496]. First method, the so-called cyclostationary CKC, requires recordings over several repetitions of dynamic muscle contractions. Second method, the so-called sequential CKC, identifies individual motor units online and does not rely on cyclostationarity of measurements. Both methods were tested on experimental surface EMG, recorded during dynamic contractions of biceps brachii muscle. In addition, tests on isometric contractions were performed in order to systematically assess their performance on signal epochs of different lengths and with different configurations of surface electrode arrays. Preliminary results revealed the CS – 17 System Software Laboratory

sequential CKC matches the performance of classical CKC, down to the epoch length of 1 second. For shorter signals the performance declines rapidly. Cyclostationary CKC is suitable for offline analysis only and requires approx. five repetitions of dynamic contraction to successfully decompose motor units. In preliminary tests on dynamic EMG, the cyclostationary CKC decomposed up to 12 motor units.

TREMOR-EEU An ambulatory BCI driven tremor suppression system based on functional electrical stimulation Leader: Asst. Prof. Dr. Aleš Holobar Participants: Prof. Dr. Damjan Zazula, Dr. Matjaž Divjak, Dr. Rok Istenič Project partners: Consejo Superior de Investigaciones Científicas, CSIC, Madrid, Spain, University of Aalborg, Denmarks, Technaid S.L., TCN, Spain

Tremor is the most common movement disorder and it is strongly increasing in incidence and prevalence with ageing. It is typically managed by means of drugs, surgery (thalamotomy), and deep brain stimulation, but treatments are not effective in approximately 25% of patients. The main objective of the TREMOR project is to validate, technically, functionally and clinically, the concept of mechanically suppressing tremor through selective Functional Electrical Stimulation (FES) based on a (Brain-to-Computer Interaction) BCI-driven detection of involuntary (tremor) motor activity. The main responsibility of System Software Laboratory is twofold: a) to increase the robustness of the TREMOR BCI system by developing and validating the online and self-learning signal decomposition techniques, capable of suppressing artefacts and extracting the central tremor component from multichannel electroencephalograms (EEG), and b) to decompose tremor affected surface electromyograms (EMG) in order to quantify neurophysiological mechanisms contributing to muscle tremor. In the first project year, 51 different signal separation techniques were systematically tested on EEG signals from six different tremor-affected patients. It was demonstrated that, although partially successful, the existing state-of-the-art techniques experience problems in convergence and are not capable of separating the central tremor component from ongoing EEG activity and artefacts. These findings motivated the development of novel decomposition approach, the so-called EMG-driven decomposition of EEG. In preliminary testing, the novel technique successfully identified the central tremor component in EEG signals from five out of six tremor-affected patients. A robust surface EMG decomposition tool, referred to as tremor-optimized Convolution Kernel Compensation (CKC) technique, has also been developed. This technique modifies and extends the previously published CKC method [A. Holobar, D. Zazula, “Multichannel blind source separation using convolution kernel compensation,” IEEE trans. signal proces., System Software Laboratory CS – 18

2007, 55(9), pp. 4487-4496] in order to circumvent the typical assumption on regularity and asynchrony of motor unit firings in normal condition and adapt to the discharge patterns in pathological tremor. In twenty-four recordings of high-density surface EMG signals from four tremor-affected patients, the modified CKC technique identified 134 motor units (6 ± 4 motor units per contraction).

Research and development project

V4-0537 Development of a register for fruit harvesting forecast for apples and pears based on visualisation of trees growing volumes (Priprava registra napovedi in pridelkov jabolk in hrušk s pomočjo vizualizacije rodnega volumna dreves) Leader: Assoc. 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, Faculty of Electrical Engineering and Computer Science

Financed by: Slovenian Research Agency (ARRS), Ministry of Higher Education, Science and Technology Duration: January 2008 to August 2010

The project was completed in collaboration between the Faculty of Agriculture and Life Sciences and the Faculty of Electrical Engineering and Computer Science. It focused on monitoring and prediction of fruit harvest, specifically of apples and pears, since in Slovenia, 72% of the fruit area is cultivated for those two types. Today's crop assessment is based on manual counting of fruits in smaller areas, resulting in a large difference between the forecast and actual annual yield. The project aimed to develop an effective, simple and, above all, a rapid data collection system for field-measurements, and thus improve the accuracy of existing harvesting- prediction methods and models. The Faculty of Electrical Engineering and Computer Science was involved in developing a computer application for data gathering, storing and processing the collected data. In 2009, we developed the subsystem for navigation, which guides a user to selected crops, as fast as possible. Data acquisition subsystem for field-measurement was based on a mobile device and connected to a computer to store the collected data. Several users can operate the system simultaneously, whereas the collected data are synchronized CS – 19 System Software Laboratory

by the central computer at a later stage. In 2010, an evaluation of the implemented subsystems and the system as a whole followed. We were verifying whether the GPS positioning system used is reliable enough to guide user to the same plantation and trees several times. Therefore, we checked the accuracy of three different GPS modules. The ASUS P565 phone proved the best, having repeatable accuracy close to 10 meters. Unfortunately, such accuracy is not sufficient to identify a particular tree in the plantation. By using GPS modules, we can only identify entire rows of trees, as the average distance between the trees in a row is 0.7 meters. The project was successfully completed in 2010 and the developed system showed to be very helpful and will be also used in the future to predict fruit harvest..

KBB – SI-AT Knowledge for Business in Border Regions Leader: Prof. Dr. Borut Žalik Participants: Dr. David Podgorelec, Dr. Gregor Klajnšek Project partners: Public Agency for Technology of the Republic of Slovenia, Chamber of Commerce and Industry of Štajerska, Pomurje Technology Park, University of Maribor, Faculty of Mechanical Engineering, University of Maribor, Faculty of Chemistry and Chemical Engineering, SFG-Innofinanz, FH Joanneum, ACstyria Autocluster GMBH, ISIS - Institut für Systemwissenschaften, Innovations- & Nachhaltigkeitsforschung - Karl-Franzens-Universität Graz

Financed by: Government Office for Local Self-Government and Regional Policy, European Commission – European Regional Development Fund

Duration: 2009 to 2012 Geometric Modelling and Multimedia Algorithms Laboratory CS – 30

The KBB project has been developed to boost activities of technology transfer in the Slovenian-Austrian border region in order to provide relevant stakeholders with the methodology to train facilitators and to pilot projects in companies until they are finished. The project is carried out as part of the Operational Programme Slovenia-Austria 2007-2013.

L2-3650 Processing of massive geometric LIDAR data Leader: Prof. Dr. Borut Žalik Participants: Dr. Bogdan Lipuš, Dr. Sebastian Krivograd, Domen Mongus, Denis Špelič Project partners: Jožef Stefan Institute (IJS) Primorska Institute of Science and Technology (PINT) IGEA d.o.o. X-Lab d.o.o.

Duration: 2010 to 2013

Acquisition and processing of geometric data from the Earth surface are complex processes that used to be considered difficult, slow and expensive. However, modern technologies enable development of devices capable of fast and cost-efficient data capturing. The focus has therefore been moved to data storage and processing. LiDAR (Light Detection and Ranging) scanners can capture up to 24 points in a square metre, with the acquisition speed as high as 200.000 points per second. The results of this are huge amounts of geometric data – 3D points with attached specific data that exceed the storage capacities of a computer system. Their storage and processing require special approaches. The development of software for huge datasets processing hardly follows capabilities of data capture devices. This implies many challenges and problems in the field of geometric data processing. In the proposed project, we deal with some of them in close cooperation with final users. The expected solutions will directly support the quality of their services. To achieve the set goals, thorough theoretical knowledge of the field, new theoretical solutions and practical experiences are necessary. Proven excellence of our previous research results and successful transfers to practice provide a good starting point. CS – 31 Geometric Modelling and Multimedia Algorithms Laboratory

INT_GEOPI Interoperability of Geo-Spatial Data Infrastructure for Spatial Development Leader: Dr. Vid Domiter Participants: Dr. Gregor Klajnšek, Dr. Bogdan Lipuš, Boštjan Pivec, Bojan Rupnik, Gregor Smogavec, Denis Obrul, Denis Žganec Project partners: IGEA d.o.o.

Financed by: Ministry of Higher Education, Science and Technology of the Republic of Slovenia, European Union – European Regional Development Fund

The project is aimed towards the construction of modern geospatial data infrastructure, especially intended for local communities and other entities that play an important role in land development. The project partners want to create technological capabilities for easier access to spatial data for both users and applications that use these data in their daily routines. The geospatial data infrastructure will be based on the latest geoinformation standards OGC and Inspire as well as on the open-source GeoServer infrastructure. This infrastructure should Geometric Modelling and Multimedia Algorithms Laboratory CS – 32

also be compatible with the interoperable infrastructure that is being built by the state. Additionally, the project partners have set a goal to raise awareness of spatial data and promote related knowledge to general public. This will be done by creating a system that will support easy and clear presentation of key characteristics of spatial data to end-users and by creating a feedback loop with the education process through which results and new knowledge obtained in the project will be available in the university education process.

Generation of graphical textual sets Leader: Prof. Dr. Borut Žalik Participants: Denis Obrul Project partners: Jakša Group d.o.o.

Financed by: Jakša Group d.o.o.

Duration: 2010

In cooperation with Jakša Group d.o.o. we have developed a generator of graphic text sets to check the validity of data in input fields on webpages. Graphical text sets are selected sequences of characters presented by a masked image that can only be read by humans.

Application for visualization of LiDAR data on personal computers Leader: Prof. Dr. Borut Žalik Participants: Sašo Pečnik Project partners: Geoin d.o.o.

Financed by: Geoin d.o.o.

Duration: 2010

Presented in this project is an interactive tool that allows efficient processing and analysis of data collected by LiDAR technology. The LiDAR technology allows quick capturing of geometric data of a large geographical area with high precision and resolution. The scope covered by data set grows rapidly and the ability of modern computer systems requires introducing optimization algorithms through the whole process of visualization, processing and analysis. We present an algorithm of point reduction from the scene, based on a hierarchical division of space using a quad-tree. We reduce points according to their visibility and distance from the viewpoint, thus ensuring real-time visualization on computer systems with a lower graphic power. Such visualization provides high system responsiveness, and presents a framework that allows processing of LiDAR data. Geometric Modelling and Multimedia Algorithms Laboratory CS – 34

BI-TR/10-12-004 Domain specific modeling language for multi-agent systems, founded for semantic web Leader: Prof. Dr. Marjan Mernik Participants: Dr. Tomaž Kosar, Dr. Matej Črepinšek, Dejan Hrnčič, Ines Čeh, Marjan Horvat Financed by: Government of the Republic of Turkey, Slovenian Research Agency (ARRS)

Duration: 1.1.2010 to 31.12.2012

Programe agents and multi-agent systems (MAS) present an efficient technology for modeling and construction of complex divided systems. Programe agents are basically autonomous programe components, which are capable to come up with a decision instead of users whose intentions are to execute given tasks. The study of multi-agent systems is currently more or less concentrated on studying intelligent agents that communicatie amongs each other. As part of this project, we will introduce domain specific modeling languages (DSML) for development of multi-agent systems by taking into consideration agents that support semantic web. The aim of this project is to create domain specific modeling language for multi-agent systems that would have a clear syntax and semantic to define multi-agent systems. It would also be based on a graphic notation from which it would be possible to automatically generate a code through the help of model transformations. Programming Methodology Laboratory CS – 38

BI-PT/10-11-230 Evaluation of understanding domain specific programs Leader: Prof. Dr. Marjan Mernik Participants: Dr. Tomaž Kosar, Dr. Matej Črepinšek, Dejan Hrnčič, Ines Čeh, Marjan Horvat Financed by: Government of the Republic of Slovakia, Slovenian Research Agency (ARRS)

Duration: 1.1.2010 to 31.12.2011

Domain specific languages are those that are suited for specific application domain and offer the user a more comparable notation and abstraction. According to the definition, domain specific languages are more pronounced and simpler to use in a specific domain as basic purpose languages and they bring benefits into productivity and in lowering the maintenance costs. However, are those claims also true in practice? All claims have a common denominator, which makes domain specific programe a lot easier to understand. Understanding of programs is a hard cognitive work, which includes construction of a mental model of the program and thoughts of the programmer who wrote the programe. That process can be simplified with concrete presentations that can be automatically acquired and they reveal different aspects of the programme as well as its structure and behavior. Therefore, the visualization and animation of programs is an important aid in order to reach previously mentioned goal. Even more important is the possibility to create visual presentations that enable the programmer to link the realization of programe sequence with their effects and with such visualize the link between a problem and a solution. In order to better understand the link between the problem domain and program domain, we will research different formalisms such as ontologies and domain analyses.

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) offer an 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 a 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 of 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. To recognize 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 to manage the gap between information technologies and different groups of users. The connecting role of informatics requires them to be familiar with knowledge IN – 2 Institute of Informatics

and skills that are related to communication methods and technologies, collaboration and team- work. Nevertheless, they should be aware of the ever growing impact of advanced technological solutions on societal processes.

Z2-3678 Ontology-based Adoption Improvement of E-Services (Ontološko podrto pospeševanje uporabe e-storitev) Leader: Dr. Luka Pavlič Financed by: ARRS

Duration: 2 years

E-services market has grown considerably. However, we can observe a poor use of these services and believe that by only providing e-service, it does not automatically mean that consumers use them. To use e-services effectively, users should primarily be aware of an e- service existence, or they should be able to find them easily. Furthermore, users should know how to use e-services easily or how to connect them in a logical sequence. In real life situations it is very rarely that we encounter situations that can be supported only with one e- service. The project deals with reduction of the presented gap between providing the e-services and using them. We are going to develop a holistic methodology, which will, in addition to offering e-services, also support to search for them in a straightforward way. The methodology will be realized with the use of a prototype platform. Inforamtion Systems Laboratory IN – 5

Testing has been performed through the use of international standards ISO/IEC 25062, ISO/IEC 14598-5 and ISO/IEC 9126. Formal part of the test has been based on user observation when executing a set of predefined tasks and scenarios. The second method used has been the heuristic evaluation. It was centered on rating the system by a control list and performing an expert audit on usability of the web application. The outcome of testing was a report on the achieved level of usability and a list of recommendations that has allowed application developers to enhance the level of usability for all groups of users or just the chosen ones.

ZRSZ-OS-2010 The study of suitability and justification of usage of open source solutions in the application portfolio of the ZRSZ (Študija primernosti in upravičenosti uporabe odprtokodnih rešitev v portfoliju aplikacij ZRSZ) Leader: Assoc. Prof. Dr. Aleš Živkovič Participants: Gregor Jošt; Asst. Prof. Dr. Gregor Polančič; Jernej Huber Financed by: ZRSZ

Duration: October 2010 to January 2011

The scope of the project was to analyze the possibilities of introduction of open source solutions into the information infrastructure of the Zavod RS za zaposlovanje (ZRSZ) and the accompanying expenses of such substitution. The result of the project was an extended presentation of the prominence of open source software in Slovenia and abroad. A view of licensing models and good practices was also provided. Furthermore, some pitfalls and downsides were addressed and resolutions were proposed. The study also offered a review of proprietary open source solutions for a theoretical portfolio of application solutions for the ZRSZ. Based on the analysis, the study presented a possible scenario for migration to the open source, which has acknowledged present solutions and past investments. The second part of the study contained a research of financial impacts of proposed migration scenarios for a five year period.

IT-FERI RR-2009 AN6211AX Leader: Prof. Dr.Matjaž Colnarič Participants: Dr.Domen Verber, MSc. Rok Ostrovršnik Project Partners: Iskratel d.o.o., Kranj

Financed by: Iskratel d.o.o., Kranj

Duration: September 2009 to December 2010

The aim of the project was to build a local data store (LDB – Local Data Base) and storage for dynamic SNMP parameters (DCT – Dynamic Configuration Table) for AN6211AX hubs in order to optimize access to large SNMP tables and to reduce network traffic. In addition, a model of DSP manager (DSP mediator) was built, which allows the addressing of several communication nodes inside the hub through the use of only one IP address. The prototype was produced in the test environment with VS2005 development tool and according to internal directives of Iskratel. All products have been installed into the customer test environment.

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

The multidisciplinary program 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 Institute of Media Communications provides the foundation, not only to perform work in radio, TV and production houses, but to prepare 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 year of studies, an emphasis is given to the theoretical part, while the practical work is carried out in the final years. The program is, in part, carried-out in media houses and similar environments so the students can gain experience with specific working areas. The above mentioned directives are also presented in the modernized study programs (Bologna study programs) for all three cycles. The first cycle begun in 2007, while the third one begun in October of 2009. In 2010 the first student graduated from the first cycle and matriculate for the MC – 2 Institute of Media Communications second cycle, which actually stands for the end of study programs renovation. The program has been carefully developed, and takes into account the development of disciplines, covered by the program, which considers the specifics of Slovenia and the regions. The curriculum is harmonized with similar programs 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.

RESEARCH PROJECTS

Current research projects

Targeted research project

V5-1024 Importance of digital technologies on the development of Slovenian AV production in the light of Europe 2020 strategy. Leader: Asst. Prof. Dr. Melita Zajc Participants: Prof. Dr. Tatjana Welzer Družovec, Assoc. Prof. Dr. Marjan Družovec, Asst. Prof. Dr. Marko Hölbl, Dr. Tina Tomažič, MSc Petra Cafnik, Andrej Sevčnikar, Jernej Burkeljca

Financed by: Slovenian Research Agency, Ministry of Culture, Ministry of Higher Education, Science and Technology.

Duration: October 2010 to March 2012

In this research, data is being collected and the content, technology and cost dimensions of modern Slovenian AV production are analyzed. We wish to verify the assumption that we are witnessing the development of a new business model, which could serve as the basis for developing additional steps to promote AV production, which would also be financially more efficient. We analyze the role of digital technologies and determine their influence on market entry as well as individual entities, cost of production and distribution options. Our goal is to determine which of these should be included in strategic planning. The collected data will enable an overview of different levels of equipment and cost demands of individual projects and as such simplify practical decisions by project managers. The platform – a database in a MC – 3 Institute of Media Communications

user friendly form – will serve as the key source of information about Slovenian AV producers and will enable them to find the most appropriate project partners. It will also act as a showroom through which Slovenian creators, experts and producers will be able to offer their services to partners in other European countries or further afield. The platform will promote further content creation for publication on the web and thus directly contribute to fulfilling the Europe 2020 strategy.
