Watersheds have been defined both for node and edge weighted graphs. We show that they are identical: for each edge (resp. node) weighted graph exists a node (resp. edge) weighted graph with the same minima and catchment basin.

The aim of phishing is tracing the users' s private information without their permission by designing a new website which mimics the trusted website. The specialists of information technology do not agree on a unique definition for the discriminative features that characterizes the phishing websites. Therefore, the number of reliable training samples in phishing detection problems is limited. M...

Efficient exploitation of the available cache memory space can have a significant improvement in program performance. By carefully restructuring a program such that temporally local sequences of instructions are mapped to different portions of the cache, fewer cache conflicts will result. In this paper we present a link-time procedure mapping algorithm which views the cache as a colored address...

An independent set in a graph G is a set of vertices no two of which are joined by an edge. A vertex-weighted graph associates a weight with every vertex in the graph. A vertex-weighted graph G is called a unique independence vertex-weighted graph if it has a unique independent set with maximum sum of weights. Although, in this paper we observe that the problem of recognizing unique independenc...
