Gradient-based numerical optimization of complex engineering designs offers the promise of rapidly producing better designs. However, such methods generally assume that the object...
Combinatorial covering arrays have been used in several testing approaches. This paper first discusses some existing methods for finding such arrays. Then a SAT-based approach a...
The problem of computing low rank approximations of matrices is considered. The novel aspect of our approach is that the low rank approximations are on a collection of matrices. W...
We extend the constellation model to include heterogeneous parts which may represent either the appearance or the geometry of a region of the object. The parts and their spatial co...
Web searching is a significant activity for many people seeking multimedia information. Major Web search engines, such as Alta Vista, are essential tools in the quest to locate re...
