Several process algebras for modelling hybrid systems have appeared in the literature in recent years. These all assume that continuous variables in the system are modelled monolit...
We present the first complete translation of XPath into an algebra, paving the way for a comprehensive, state-of-theart XPath (and later on, XQuery) compiler based on algebraic op...

Priority is a frequently used feature of many computational systems. In this paper we study the expressiveness of two process algebras enriched with different priority mechanisms...
Statecharts is a visual language for specifying the behavior of reactive systems. The language extends nite-state machines with concepts of hierarchy, concurrency, and priority. De...
We show that the class of Petri nets is less expressive with respect to bisimulation equivalence than the class of PA processes extended with a finite state control unit. Key word...
