The parallel version of precondition techniques is developed for matrices arising from the Galerkin boundary element method for two-dimensional domains with Dirichlet boundary conditions. Results were obtained for implementations on a transputer network as well as on an nCUBE-2 parallel computer showing that iterative solution methods are very well suited for a MIMD computer. A comparison of nu...

Abstract Two-level Schwarz domain decomposition methods are very powerful techniques for the efficient numerical solution of partial differential equations (PDEs). A two-level method requires two main components: a one-level preconditioner (or its corresponding smoothing iterative method), which is based on techniques, and coarse correction step, relies space. The space must properly represent ...

We propose an algorithm, SoftPOSIT, for automatic model-to-image registration. This algorithm combines two techniques, (1) a solution to the correspondence problem by an iterative technique called Softassign, and (2) a solution to the pose problem by an iterative technique called POSIT. These two techniques are combined into a single iteration loop. The present report focuses on the description...

In recent years, the yeast two-hybrid system has become the method of choice for detection and analysis of protein-protein interactions in an in vivo context. This system, which capitalizes on the significant genetic history and ease of protocols for manipulation of Saccharomyces cerevisiae, is accessible to most laboratories and is applicable to the pursuit of a large variety of experimental g...
