This paper discusses semiotic engineering (a design methodology) and its potential for addressing issues concerning the adoption and configuration of assistive technologies. Categ...
Attempts at classifying computational problems as polynomial time solvable, NP-complete, or belonging to a higher level in the polynomial hierarchy, face the difficulty of undecid...
Location models are crucial to location-aware applications. In this paper we present two approaches for modeling location information in an infrastructure-based and an ad hoc netwo...
Abstract. Experiences with the management of Grid specific monitoring and accounting data have shown that current approaches do not sufficiently support a distinction between prov...
In Grid systems, nontrivial qualities of service have to be provided to users by the resource providers. However, resource management in a decentralized infrastructure is a complex...
