We present an algorithm for computing Minkowski sums among surfaces of revolution and surfaces of linear extrusion, generated by slope-monotone closed curves. The special structur...
This paper describes an Ei el system for rapid testing of grammars. Grammars are de ned in an extended BNF notation that allows actions on the parse tree nodes to be de ned as add...
Abstract. Domain specific modeling languages are of increasing importance for the development of software and other systems. Meta tools are needed to support rapid development of d...
Effective automatic summarization usually requires simulating asoning such as abstraction or relevance reasoning. In this paper we describe a solution for this type of reasoning in...
Current networked information systems on the Internet, whilst extremely successful, run into problems of fragmentation, consistency, scalability, and loss of orientation. The deve...
