We demonstrate that it is possible to filter an image with an elliptic window of varying size, elongation and orientation with a fixed computational cost per pixel. Our method inv...
The ForSyDe methodology has been developed for system level design. In this paper we present formal transformation methods for the refinement of an abstract and formal system mode...
In this paper we propose a behavioural model, namely the Extended Modal Labeled Transition Systems, as a basis for the formalization of the different notions of variability usuall...
Schema statements in OWL are interpreted quite differently from analogous statements in relational databases. If these statements are meant to be interpreted as integrity constrai...
The correctness of the Z semantics of OWL is the theoretical foundation of using software engineering techniques to verify Web ontologies. As OWL and Z are based on different logi...
