This paper describes ProSQL, a novel prototyping tool to support the development of extensions to SQL. ProSQL provides a simple way to prototype the features of a proposed extensio...
ABSTRACT. This paper focuses on the assignment of meaning to some nonterminating SLD derivations in logic programming. Several approaches have been developped by considering infini...
Based on radial basis functions approximation, we develop in this paper a new computational algorithm for numerical differentiation. Under an a priori and an a posteriori choice r...
We develop duality between nuclei on Heyting algebras and certain binary relations on Heyting spaces. We show that these binary relations are in 1–1 correspondence with subframe...
The stability method is very useful for obtaining exact solutions of many extremal graph problems. Its key step is to establish the stability property which, roughly speaking, sta...
