Ray-tracing is a well-known method for producing realistic images. If we wish to view a ray-traced image stereoscopically, we must create two distinct views of the image: a left-e...
In many cases, a logic program can be divided into two parts, so that one of them, the \bottom" part, does not refer to the predicates de ned in the \top" part. The \bot...
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...
In a distributed system or communication network tasks may need to be executed on more than one processor. For time-critical tasks, the timing constraints are typically given as e...
This paper discusses three techniques useful in relaxing the constraints imposed by control flow on parallelism: control dependence analysis, executing multiple flows of control s...
