We study three operational models of name-passing process calculi: coalgebras on (pre)sheaves, indexed labelled transition systems, and history dependent automata. The coalgebraic...
Nowadays, people start to accept fuzzy rule–based systems as flexible and convenient tools to solve a myriad of ill–defined but otherwise (for humans) straightforward tasks s...
In this paper we present a semantic theory for Concurrent ML. It consists of a new effect-based type system and a denotational model. The new type system is based on an extension o...
Many environments in which humans wayfind can be conveniently abstracted as networks or graphs: structures of nodes that are interconnected by edges. Examples include the street ne...
ion suffices ("decide which type you want and provide a full set of operations for each type"). If the application domain is, say, the administration of a university, the...
