This paper addresses the frame problem for programming theories that support both sharing and encapsulation through specification variables. The concept of dynamic frames is introd...
Timed and weak timed simulation relations are often used to show that operations on hybrid systems result in equivalent behavior or in conservative overapproximations. Given that s...
We propose a situation calculus formalization of action domains that include numeric-valued fluents (so-called additive or measure fluents) and concurrency. Our approach allows fo...
We present a system for the formal verication of processors which combines a computer algebra simplication tool with an object-oriented approach. It has been successfully used f...
E-learning by doing is an important e-learning process, that provides several advantages but that requires a high interactivity degree, not always supported in e-learning contexts...
