The (axis-parallel) stabbing number of a given set of line segments is the maximum number of segments that can be intersected by any one (axis-parallel) line. We investigate probl...
In this paper, we discuss and compare several policies to place replicas in tree networks, subject to server capacity and Quality of Service (QoS) constraints. The client requests ...
Tree based indexing structures like -trees, ·-trees, Bitmap indexes and Ê-trees have become essential for getting good performance when accessing vast datasets. However, most dat...
