This article discusses visualizing and interacting with 3-D geographical data via VRML in the Web environment. For this purpose, the Web-based desktop VR for geographical informat...
E cient data-parallel spatial join algorithms for pmr quadtrees and R-trees, common spatial data structures, are presented. The domain consists of planar line segment data i.e., Bu...
Consider a center possessing a trusted (tamper proof) device that wishes to securely compute a public function over private inputs that are contributed by some network nodes. In ne...
