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)
Efficient information sharing is very important for emergency and rescue operations. Mobile ad-hoc Networks (MANETs) are often the only network environment for such operations. We have developed the MIDAS data space (MDS) to transparently share information among rescue applications in such environments. To achieve the required level of availability for(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)
