Petri nets are a formalism for modelling and validating critical systems. Generally, the approach to specification starts from an abstract view of the system under study. Once val...
Abstract. This paper presents simulation-based relations for probabilistic game structures. The first relation is called probabilistic alternating simulation, and the second called...
Refinement semantics is an alternative to least fixpoint semantics that is more useful for programming. From it we derive a variety of rules for w h i l e-loops, for-loops, and loo...
Trajectory generation for nonlinear control systems is an important and difficult problem. In this paper, we provide a constructive method for hierarchical trajectory refinement. ...
Fuzzy relations as representational tools and fuzzy compositional operators as reasoning components, are user in this paper in order to represent knowledge expressed in semantic ru...
