Abstract:
The research in the department is structured around four 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.In the field of underwater acoustics important research projects are developed since 1985. Fundamental as well as applied research is carried out in the field of the modelling of marine systems, marine acoustics, subbottom profiling and sediment classification. Marine environmental studies based on GIS-techniques are of prime importance in this group as well.
  4. Identification of biogeochemical signals & systems (IBiSS):
    - Pre- and post-signal processing of solid substrate measurements
    - Parameter estimation and constrained optimization of climatological and ecological models
    - Validation of environmental models

The long term goal is to build measurement based models for environmental systems. The current trend is to build more complex models in order to simulate the ‘real’ world, while a ‘good’ model is not necessarily the most complex model. On the contrary, it only needs that complexity, which is supported by experimental measurements. It has to be able to describe all significant variation in the data, without modelling the stochastic measurement uncertainties. These models are used for two purposes: (i) to extract the maximum amount of significant information out of noisy measurements; (ii) to make future predictions.
