We define a formal execution semantics for UML activity diagrams that is appropriate for workflow modelling. Our semantics is aimed at the requirements level by assuming that sof...
—One of the key challenges in modern real-time embedded systems is safe composition of different software components. Formal verification techniques provide the means for design...
Recently we have proposed the ”almost ASAP” semantics as an alternative semantics for timed automata. This semantics is useful when modeling real-time controllers : control str...
Masaccio is a formal model for hybrid dynamical systems which are built from atomic discrete components (di erence equations) and atomic continuous components (di erential equation...
PLC-Automata are a class of real-time automata suitable to describe the behavior of polling real-time systems. PLC-Automata can be compiled to source code for PLCs, a hardware wide...
