The standard versions of HOL only support disjoint sums over finite families of types. This paper introduces disjoint sums over type classes containing possibly a countably infinit...
Intelligence, collaboration and mobility are the main important features in designing agents for electronic commercial systems. But very few systems permit to implement agents whi...
We describe the integration of a structuredtext retrieval system (TextMachine) into an object-oriented database system (OpenODB). We use the external function capability of the da...
Asynchronous circuits have received much attention recently due to their potential for energy savings. Process algebras have been extensively used in the modelling, analysis and sy...
A programming construct mixin was invented to implement uniform extensions and modifications to classes. Although mixin-based programming has been extensively studied both on the m...
