Four years ago-in December 1997-the first European Science Foundation Workshop on Cardiovascular Specific Gene Expression was held in Maastricht. It was hardly possible to imagine the progress in the field in those four years. In 1997, gene expression was still an art focused on individual genes; in 200 I, many labs have access to micro-array facilities to determine the expression of thousands of genes simultaneously. In 1997, gene expression was an area of fundamental research in basis molecular biology laboratories; in 200 I, clinical cardiovascular research has incorporated gene expression...

This volume contains revised papers that were presented at the international workshop entitled Computational Methods for Algebraic Spline Surfaces ("COMPASS"), which was held from September 29 to October 3, 2003, at Schlo Weinberg, Kefermarkt (A- tria). The workshop was mainly devoted to approximate algebraic geometry and its - plications. The organizers wanted to emphasize the novel idea of approximate implici- zation, that has strengthened the existing link between CAD / CAGD (Computer Aided Geometric Design) and classical algebraic geometry. The existing methods for exact implicitization...
