In this paper we investigate updates of knowledge bases represented by logic programs. In order to represent negative information, we use generalized logic programs which allow de...
In this paper, we study the modelization of biochemical reaction by using concurrent constraint programming idioms. In particular we will consider the stochastic concurrent constra...
In traditional information-flow type systems, the security policy is often formalized as noninterference properties. However, noninterference alone is too strong to express securi...
In 1996, Gil and Lorenz proposed programming language constructs for specifying environmental acquisition in addition to inheritance acquisition for objects. They noticed that in ...
Abstract. We present a semantics and answer set programs for relational peer data exchange systems. When a peer answers a query, it exchanges data with other peers in order to supp...
