Program compilation can be formally defined as a sequence of equivalence-preserving transformations, or refinements, from highlevel language programs to assembler code. Recent mo...
A low-cost on-line test scheme for digital filters is proposed. The scheme uses an invariant of the digital filter, the frequency response at specific points, in order to detect p...
Among the formalisms for qualitative spatial reasoning, the Region Connection Calculus and its variant, the constraint algebra RCC8, have received particular attention recently. A...
Recent efforts in the Conceptual Modelling community have been devoted to properly capturing time-varying information, and several proposals of temporally enhanced Entity-Relation...
This paper describes a simulation tool for the analysis of complex jobs described in the form of task graphs. The simulation procedure relies on the PN-based topological represent...
