A Golomb ruler with <i>M</i> marks can be defined as a set {<i>a<sub>i</sub></i>} of integers so that all differences &delta;<sub><i>ij</i></sub> = <i>a<sub>...

In this paper we propose a mathematical model for the dimensioning of a 3G multimedia network and design a Tabu Search heuristic to solve it. The model is a...

Consider <i>N</i> entities to be classified (e.g., geographical areas), a matrix of dissimilarity between pairs of entities, a graph <i>H</i> with vertices a...

We define two classes of lower bounds using either one or two simplices for the minimization of a concave function over a polytope. For each of them, a pro...

This paper presents an analysis of the forward link capacity of a cellular network, based on IS-95 CDMA technology. The forward link, or downlink, refers to...
