Alternating timed automata are a powerful extension of classical Alur-Dill timed automata that are closed under all Boolean operations. They have played a key role, among others, ...
In this paper, we present weighted/priced timed automata, an extension of timed automaton with costs, and solve several interesting problems on that model. Key words: Weighted/pri...
The aim of the work is twofold. In order to face the problem of modeling time constraints in Promela, a timed extension of the language is presented. Next, timed Promela is transla...
Multitasking in user behavior can be represented along a continuum in terms of the time spent on one task before switching to another. In this paper, we present a theory of behavi...
In this paper we present a novel system for monitoring a computer user’s posture and activities in front of the computer (e.g., reading, speaking on the phone, etc.) for self-re...
