In this paper, we initiate the study of the approximability of the facility location problem in a distributed setting. In particular, we explore a trade-off between the amount of...
Abstract. When dealing with distributed systems, one of the most important problems that has to be addressed is concurrency. Distributed systems are inherently concurrent, distribu...
On cc-NUMA multi-processors, the non-uniformity of main memory latencies motivates the need for co-location of threads and data. We call this special form of data locality, geogra...
In Reverse Engineering a physical object is digitally reconstructed from a set of boundary points. In the segmentation phase these points are grouped into subsets to facilitate co...
—The concept of groups is a natural aspect of most collaboration scenarios. Group-Centric Secure Information Sharing models (g-SIS) have been recently proposed in which users and...
