Modeling systems based on semi-formal graphical formalisms, such as Statecharts, has become standard practice in the design of reactive embedded devices. However, the modeling of ...
We present an extension of a mathematical framework proposed by the authors to deal with the composition of heterogeneous reactive systems. Our extended framework encompasses dive...
We study the construction of labelled transition systems from reactive systems defined over directed bigraphs, a computational meta-model which subsumes other variants of bigraphs...
We present an operational model for describing random reactive systems. Some models have already been proposed for this purpose, but they generally aim at performing global reason...
Default reasoning has become an important topic in software engineering. In particular, defaults can be used to revise speci cations, to enhance reusability of existing systems, an...
