In qualitative spatial reasoning, the last ten years have brought a lot of results on theories of spatial properties and relations taking regions of space as primitive entities. In...
We introduce the concept of a group principal and present a number of different classes of group principals, including threshold-group-principals. These appear to naturally usefu...
Our concern in this paper is with conjecturing diagnoses to explain what happened to a system, given a theory of system behaviour and some observed (aberrant) behaviour. We charac...
Several types of network trafic have been shown to exhibit long-range dependence (LRD). In this work, we show that the busy period of an ATM system driven by a long-range dependen...
Abstract. We introduce a compositional characterization of the operational semantics of equational Horn programs. Then we show that this semantics and the standard operational sema...
