We give a denotational framework (a "meta model") within which certain properties of models of computation can be understood and compared. It describes concurrent proces...
— We consider the problem of scheduling packets over a number of channels with time varying connectivity. Policies proposed for this problem either stabilize the system when the ...
Abstract. We introduce the class of event-clock visibly pushdown automata (ECVPAs) as an extension of event-clock automata. The class of ECVPAs, on one hand, can model simple real-...
Message Sequence Charts (MSCs) are a well known language for specifying scenarios that describe how different actors (e.g., system components, people, or organizations) interact. M...
This paper provides a linguistic semantic analysis of time and aspect in natural languages. On the basis of topological concepts, notions are introduced like the basic aspectual op...
