To develop efficient algorithms for the reachability analysis of timed automata, a promising approach is to use binary decision diagrams (BDDs) as data structure for the representa...
This paper describes a new approach to visualization of scenarios within the use case-based engineering of functional requirements – the so-called Video Camera metaphor. The Vid...
Abstract. In the context of methodologies intended to confer robustness to geometric algorithms, we elaborate on the exact-computation paradigm and formalize the notion of degree o...

A special final coalgebra theorem, in the style of Aczel's [2], is proved within standard Zermelo-Fraenkel set theory. Aczel's AntiFoundation Axiom is replaced by a varia...
We show our approach for the definition of Domain Specific Languages integrating both graphical and textual views. The approach is based on the meta-modelling concepts provided by ...
