We define three composition and structuring concepts which reflect frequently used refinements of ASMs and integrate standard structuring constructs into the global state based ...
Abstract. This paper represents the beginning of a study aimed at devising semantic models for true concurrency that provide clear distinctions between concurrency, parallelism and...
We consider type systems that combine universal types, recursive types, and object types. We study type inference in these systems under a rank restriction, following Leivant'...
In this paper we investigate the development of an embedded and mobile geographic information system. Its main characteristics concern the possibility to access various informatio...
Concurrency in Logic Programming has received much attention in the past. One problem with many proposals, when applied to Prolog, is that they involve large modifications to the...
