The disk dimension of a planar graph G is the least number k for which G embeds in the plane minus k open disks, with every vertex on the boundary of some disk. Useful properties ...
: Biologists and philosophers that debate the existence of the species category are split into two main camps. Some believe that the species category does not exist and that the te...
We show that randomization can lead to significant improvements for a few fundamental problems in distributed tracking. Our basis is the count-tracking problem, where there are k...
This paper extends basic software-testing theory to software components and adds explicit state to the theory. The resulting theory e enough to abstractly model the construction o...
We study a novel hierarchical wireless networking approach in which some of the nodes are more capable than others. In such networks, the more capable nodes can serve as Mobile Ba...
