The notion of certain answers arises when one queries incompletely specified databases, e.g., in data integration and exchange scenarios, or databases with missing information. W...
We consider the problem of partitioning the set of vertices of a given unit disk graph (UDG) into a minimum number of cliques. The problem is NP-hard and various constant factor a...
This paper explores the issues and the techniques of enabling multimedia applications for the thin client computing. A prototype of a video communication system based on H.323 fam...
In this paper, we consider a generic model of computational grids, seen as several clusters of homogeneous processors. In such systems, a key issue when designing efficient job al...
Energy consumption and heat dissipation have become key considerations for modern high performance computer systems. In this paper, we focus on non-clairvoyant speed scaling to mi...
