The Numerical Propulsion System Simulation (NPSS) project has been initiated by NASA to explore the use of computer simulation in the development of new aircraft propulsion techno...
: The EM-4 is a supercomputer that offers very fast inter processor communication and support for multi threading. In this paper we demonstrate that the EM-4, Together with an auto...
The basic concept for processing spatial joins consists of two steps: First, the spatial join is performed on the minimum bounding rectangles of the objects by using a spatial acce...
The generation of efficient code for Prolog programs requires sophisticated code transformation and optimization systems. Much of the recent work in this area has focussed on hig...
We consider the decision problem for quantifier-free formulas whose atoms are linear inequalities interpreted over the reals or rationals. This problem may be decided using satisf...
