When students first learn programming, they often rely on a simple operational model of a program’s behavior to explain how particular features work. Because such models build o...
We study the monitoring and fault-diagnosis problems for dense-time real-time systems, where observers (monitors and diagnosers) have access to digital rather than analog clocks. ...
This paper presents behavior contracts as a new assertion mechanism and a tool that uses such contracts to support the testing of Object-Oriented (OO) systems. A behavior contract...
A virtual organization (VO) is a dynamic collection of entities (individuals, enterprises, and information resources) collaborating on some computational activity. VOs are an emer...
The time-bounded reachability problem for continuoustime Markov chains (CTMCs) amounts to determine the probability to reach a (set of) goal state(s) within a given time span, suc...
