Abstract. A top-down parsing algorithm has been constructed to accommodate any form of ambiguous context-free grammar, augmented with semantic rules with arbitrary attribute depend...
We show that the idea of predicates on heap objects can be cast in the framework of predicate abstraction. This leads to an alternative view on the underlying concepts of three-val...
Abstract. There are a range of abstractions used for both modelling and proof modern computational systems. While these abstractions may have been devised for specific purposes, t...
Abstract--We propose an extension to the event-based programming model for sensor-driven ubiquitous computing applications. The extension consists of three abstractions: MultiEvent...
Abstract. Qualification has been recently introduced as a generalization of uncertainty in the field of Logic Programming. In this paper we investigate a more expressive language f...
