Real-time control systems are complex to design, and automation support is important. We are interested in systems with multiple tasks, each with multiple modes, implementing a fu...
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...
Timing and power consumption of embedded systems are state and input data dependent. Formal analysis of such dependencies leads to intervals rather than single values. These inter...

We develop a revealed-preferencetheory for multiple agents. Some features of our construction, which draws heavily on Jeffrey's utility theory and on formal constructions by D...
