This paper presents an architecture specified within the project " Plug-and-play for Network and Teleservice Components " supported by The Norwegian Research Council. The hardware and software parts, as well as complete network elements that constitute a communication system, shall have the ability to configure themselves when installed into a network and(More)
Traceability is an important feature in model-driven development. Many research initiatives are currently investigating how to collect, store and utilize traceability information to improve the quality of the MDD process, and there is a need to unify the results from these initiatives. This paper proposes a generic solution for traceability that offers a(More)
Cerebral blood flow (CBF) and cerebral metabolic rate for oxygen (CMRO2) were measured by a modification of the Kety-Schmidt technique using i.v. xenon-133 in 20 patients undergoing craniotomy for supratentorial cerebral tumours. Anaesthesia was induced and maintained with midazolam, fentanyl and nitrous oxide. Pancuronium was given for neuromuscular block.(More)
A plug-and-play (PaP) architecture to be applied for specification and execution of telecommunication systems functionality is presented. The architecture is based on a theatre metaphor. Plays define the functionality of the system. PaP components are realised by actors playing roles defined by manuscripts. An actor's capabilities define his possibilities(More)
An architecture for plug-and-play to be applied for telecommunication systems is presented. The architecture is based on a theatre metaphor. Plays define the functionality of the system. PaP components are realised by actors playing roles defined by manuscripts. An ac-tor's capabilities define his possibilities for playing various roles. The usability of(More)
