Our goal is to educate successful, self-confident specialists with vision and knowledge. It is important with what knowledge we provide our future graduates, what type of character to develop, and how to help them on their way to achieving these goals. Our Faculty offers a great variety of different and developing fields, and as such, the only possible way to be successful, is with the strength of the scientific research work of our professors, assistants and researchers. That is why the most important element in the current, quality pedagogical work is following the latest events in the world and being creative and cooperative in the development of our own scientific research work. A frequently asked question here is: Are we tilting at windmills? How can we comprehend the Europe’s and the World’s scientific research sphere on equal terms when we lack space, human potential, and financial resources in comparison to our European sister faculties and in the hard economic situation of our society? Is it possible for the voices of our researchers to be heard on the global stage? Fortunately, many among us have proven that this is possible. At our Faculty we have participated in different international projects and published important research results in the most prestigious scientific publications. Our works have been recognized by foreign scientists, and our ideas are protected by international patents. Our researchers have been educated at various recognized foreign universities and institutes. We have never believed that being the best in the local arena is good enough. If this were the case, we would have had to start regressing and would have lost contact with actual events. We have created a criterion for ourselves, our researchers and graduates which suits today’s global conditions. Despite the problems, we have managed to equip our laboratories, to obtain experienced researchers, and maintain good relations with our partner institutes in Europe and throughout the world. Our information infrastructure is solid; therefore, we will be even more demanding in maintaining this strength. There are 9 institutes at the Faculty of Electrical Engineering and Computer Science: the Institute for Automation, Institute for Electronics, Institute for Information Systems, Institute for Mathematics and Physics, Institute for Media Communications, Institute for Power Engineering,
