This paper presents an extension to the Semantic Web Rule Language and a methodology to enable advanced mathematical support in SWRL rules. This solution separates mathematical and problem semantics allowing the inclusion of integration, differentiation and other operations not built-in to SWRL. Using this approach, it is possible to create rules to cope(More)
This paper describes pilot experiences of distance learning using videoconference over the public Integrated Services Digital Network (ISDN). Graduate and postgraduate courses of the Technical University of Madrid (Telecommunication Engineers) form the educational scenario chosen for the experiences. Several phases were defined to carry out the experiments,(More)
This paper presents a framework based on ontologies, rules and mathematical semantic representation standards, for the automatic calculation of the level of quality of service perceived by the customers in telematic services. This automation is achieved by representing and using the mappings between technical quality of service and quality of experience in(More)
– This paper presents the hardware/software architecture of the Sky-Eye UAS prototype. In particular it details the hardware of the prototype, its operational concept and the software avionics architecture. The software architecture is named UAS Service Abstraction Layer (USAL) and consists on the set of standard services required for most UAS missions. The(More)
This paper presents a novel technique for synthesis of speed-independent circuits. It is based on partial order representation of the state graph called STG-unfolding segment. The new method uses approximation technique to speed up the synthesis process. The method is illustrated on the basic implementation architecture. Experimental results demonstrating(More)
