We propose a distributed data structure for maintaining spatial data sets on message-passing, distributed memory machines. The data structure is based on orthogonal bisection tree...
Abstract. The ELAN system is an environment for specifying and prototyping constraint solvers, theorem provers and deduction systems in general. It also provides a framework for ex...
Although modern control theories have been successfully applied to solve a variety of problems, they are often mathematically and physically too specific to describe and analyze t...
We present a deductive data model for concept-based query expansion. It is based abstraction levels: the conceptual, the expression and the occurrence level. Concepts and their re...
Mb describe the design and implementation of a constraint management facility for our active object-oriented database system called Jasmine/A. The facility includes integrity cons...
