The research in the department ELEC is structured around three main topics: 1. Set-up of computer controlled measurement systems, design of new intelligent instruments, processing of the measured data and the implementation of A.I. techniques in instruments for the automatic interpretation of the acquired measurements, with a lot of applications in earth science. The research in telecommunication deals with voice coded transmissions (telephony) and with robust coded digital transmission. And in the field of underwater acoustics, fundamental and applied research is carried out in the field of the modelling of marine systems, marine acoustics, subbottom profiling and sediment classification. 2. Study and development of basic concepts on identification theory with applications towards linear, non-linear, lumped and distributed systems and covering the disciplines of mechanics and electrical power engineering. Special attention is devoted to the design of optimal experiments. 3.The study of the modelling and the development of vectorial measurements methods for non-linear microwave telecommunication components and systems are central in the research. Implementation of engineering and physics concepts for the improving of image quality evaluation and dose in radiology.
