The research program covers a wide range of interdisciplinary research in the fields of telecommunications and electronics. To a large extent this is a continuation of previous research in the fields of human-machine interactions, sensors and motion analysis, e-medicine, telecommunication infrastructure and services, optimization and design of integrated circuits. In this document we sumarize some key highlights of the future research and the expected outcomes in these areas. In the field of human-computer interaction we will examine the possibility of multi-modal human-machine interaction based on the shared use of a large number of communications channels in user interfaces. We will focus also on recognition of the current mood and feelings of the user and his or her social signals. In the context of research on the use of different wearable sensors, the activities will be directed in exploring the possibilities for motion capture and motion analysis with devices having wireless communication support and facilitating biological feedback. In the field of telecommunication infrastructure the research work will continue on the fixed and mobile convergence by fiber-radio technology as well as development of new antennas for millimeter wave MIMO. The new focus will be on the optimization of radiofrequency and optical continuously tunable delay lines which are part of advanced access networks and optical interconnects for data centers. We will also seek solutions for smart electricity grids. In the area of ​​quality services for domain-specific applications we our research will include studies of selected applications and defining procedures and metrics for objective monitoring of application-level QoS. We will work on e-health solutions, with emphasis on the use of sensors (wearable computing) and develop applications in different domains (medicine, ecology, sport, environment, etc.). We will cover advanced medical signal data and image processing, as well as satellite imaging. Special focus will be given on multimedia services, content delivery, education and personalization. In next five years we intend to focus also on the introduction of update formulas for approximating the matrix of second derivatives into direct search algorithms. The obtained information on second derivatives will be used for accelerating the convergence of direct search algorithms. In the research area of metaoptimization we intend to optimize the parameters and the algorithm structure of optimization algorithms. In the field of algorithms for DataFlow computers the research will continue in the direction of the adaptation of the most used telecommunication algorithms. In the domain of electronic systems, we will develop new methods for designing complex electronic circuits with the emphasis on circuit verification and testing, research and development of electronic circuits for specific applications targeting communications, logistics, transport and image and speech processing.
Significance for science
The proposed research results and findings in the fuield of human computer interaction and motion analysis based on wearable sensors will thus be of interest to a wide range of scientific fields and individuals, and will provide the basis for further multi-disciplinary research. The proposed mechanisms in user interfaces and concrete algorithms will also benefit staff at firms engaged in the design of advanced information and communication devices and applications.   By the methods of machine learning based on diagnostic data and corresponding diagnoses one can build and verify diagnostic procedure model. Such machine-proposed diagnoses can lighten up the burden of medical personnel as it allows for more precise evaluation of a medical condition.   Research in the field of e-health and m-health will integrate the disciplines of telecommunications, communications technology and medicine. The results of these interdisciplinary research activities will contribute an important knowledge in the areas of uptake solution for e-health and m-health in the real environment. The will also contribute to implementation of these services in Europe with the possibility of international integration and transparent transfer of technology.   In the area of telecommunication networks and services the proposed research on SDN and 5G will contribute significantly to the further development of heterogeneous communication networks in the context of the performance of network technologies and the Internet of the future, which in the future will combine wireless, mobile, satellite and fixed communications solutions. In the field of optical communication there is no unique and optimal solution for routing, modulation level and spectrum allocation for the next-generation core transport network in relation to the access network.   In the field of integrated circuit design we will investigate new approaches in designing complex digital electronic systems, new methodology of verification and testing, new electronic systems targeting specific domains which, due to high-speed data processing, require implementation with application-specific integrated circuits.   The efficient processing of data, algorithm execution speed-up, possible energy and space savings, can open new research possibilities, which were before, because of different obstacles, not possible or not accomplished in a foreseeable time. We expect the new algorithm for updating the matrix of second derivatives without using first derivative information will become one of the basic building blocks of quasi-Newton direct search algorithms. The fast convergence of quasi-Newton algorithms is expected to reduce the time needed for circuit sizing. We expect to open a new area of research by applying machine learning to meta-optimization of the parameters and the structure of optimization algorithms.
Significance for the country
The proposed research program envisages cooperation with other European research institutions in the field of information technology and telecommunications, and will facilitate joint work on specific research and a search pratical solutions.   We believe that developed access networks for 100 Gbit/s based on convergence between optical and radio communications – »fiber-radio« technology will provide new opportunities in information society. In additional, the newly-developed telecommunication components, such as continuously tunable delay lines and electro-optical oscillators, can be used in the field of electrical engineering as well as for various instrumentation devices e.g. particle accelerators, radio telescope arrays, and for process control systems where precise distribution of signals is important.   The knowledge of optimization algorithms represents the foundation for the development of advanced systems for computer aided circuit and system design. It is also important in the area of machine learning, adaptive systems, and artificial intelligence. The process of developing modern information technologies involves at least one of these areas of expertise. Activities in the area of optimization put Slovenia on the research map of the world and accumulate the knowledge needed for achieving competitiveness in a world where accurate and timely information are becoming the primary goods.   Efficient data processing has diverse influences on many areas of our social and private life. The most important influence of data flow computer usage is seen in great energy and space savings. For instance, the processing of the same amount of data on a dataflow computer, in comparison to the classical computer, savings up to twenty times in energy and up to twenty times in equipment space can be expected.   We see our research group as a generator of innovations in the field of multimedia services, thus making a contact of Slovenian technological community with most recent international advances in this field. As renowned researchers we promote the Slovenian know-how in the European research and technology space.
