Abstract Role-based access control RBAC has recently received a lot of attention due to its exibility, expressive power and simplicity in administration. In RBAC permissions are as...
Continuous system dynamics can be described by, possibly large, systems of di erential equations. These can be either ordinary di erential equations (ODEs) or contain algebraic con...
Schedulability analysis of fixed priority preemptive scheduled systems can be performed by calculating the worst-case response-time of the involved processes. The system is deemed...
A 1968 study of the software process led, inter alia, to the observation that the software process constitutes a feedback system. Attempts at its management and improvement must t...
In this paper we describe our experiments on digital video applications, concentrating on the static and dynamic tradeo s involved in video playback. Our results were extracted fr...
