Web search engines are facing formidable performance challenges due to data sizes and query loads. The major engines have to process tens of thousands of queries per second over t...
Metacomputing infrastructures couple multiple clusters (or MPPs) via wide-area networks. A major problem in programming parallel applications for such platforms is their hierarchi...
In an uncertain database, each data item is modeled as a range associated with a probability density function. Previous works for this kind of data have focussed on simple queries...
We present a data structure which represents a wellshaped convex tetrahedral mesh, M, in linear space such that path traversals visiting a sequence of K tetrahedra require O (K/ l...
A method for automatically improving the performance of construction operations was developed by the integration of computer simulation and belief networks. The simulation model i...
