van den Broek, A.C. (author), Dekker, R.J. (author), Smith, A.J.E. (author), de Vries, F.P.P. (author), TNO Fysisch en Elektronisch Laboratorium (author)We have studied an optimal target detection procedure for polarimetric SAR data by using PHARUS data collected during the MIMEX campaign. The detection method is especially suitable when no a priory knowledge of the target is available. We have found that polarimetric whitening filtering preceding an order-statistics CFAR detector gives the best...conference paper 1999

Gerini, G. (author), Visser, H.J. (author), TNO Fysisch en Elektronisch Laboratorium (author)In this paper we present an efficient theoretical formulation for a full-wave analysis of phased Arrays conformal to cylindrical structures. The theory is based on an integral equation formulation and the Unit Cell Approach. Thanks to its generality and efficiency, this method represents a good starting point for the development of accurate CAD...conference paper 1999

Mooi, H.G. (author), Koenis, P.T.G. (author), Huétink, J. (author), TNO Wegtransportmiddelen (author)The purpose of the research project of which this paper is a result is to gain insight in design and control parameters of aluminium extrusion by FE simulations. This is done by means of a thermal FE code based on an ALE algorithm (Dieka). A short overview is given of the material models as well as the FE methods that are used. It is shown that...article 1999

Zuurbier, J. (author), Göbel, M.P. (author)In recent years, there is an increasing interest in optimising driver-vehicle interaction by improving vehicle dynamics. Understanding the relation between subjective and objective assessment of vehicle dynamics is an increasingly important issue. There are several reasons for these developments. Firstly, vehicle design engineers experience that...conference paper 1999

The cDNAs share high homology with the barley LoxA cDNA. Southern blotting experiments indicate single copy numbers of the three lipoxygenase genes. RFLP mapping revealed the presence of single lipoxygenase loci. LoxA and...article 1999
