Special attention was being given to speed and the numerical aspects resulting in the development of several new numerically reliable and very efficient algorithms. Furthermore, the method has been applied for the first time to medical renography, transfer function modeling and subset selection. During her postdoctoral research, Sabine Van Huffel worked out further generalizations and applications. At present, research is focused to structured total least squares problems. Special attention is being given to the improvement of quantification methods for time-domain NMR signals.
Extensive use is made of techniques in linear algebra, such as the singular value decomposition.
Improvements of the currently used methods, which are all based on the Beer-Lambert law, are being investigated. This research is performed in close cooperation with Prof. P. Casaer, Department of Paediatrics and Neonatal Medicine, Development Neurology Research Unit, University Hospital Gasthuisberg, Leuven. There are 9 participating teams and Dirk Van Ormondt from the Spin Imaging Group, Faculty of Applied Physics, T.U.Delft, is the central coordinator. The aim is to formalize and extend current collaboration within WGS into a European network to coordinate the development of robust numerical software for control systems analysis and design. In December 1998 the EC Commission approved the implementation phase for 4 years.
