Traditionally, collaborative systems have been difficult to conceive, design and implement. Although several requirements involved in these products are recurrent, some become inv...

This paper presents the generalization of weighted distances to modules and their computation through the chamfer algorithm on general point lattices. The first part is dedicated ...
We consider the generalized on-line two-server problem in which at each step each server receives a request, which is a point in a metric space. One of the servers has to be moved ...
We give explicit constructions of sets S with the property that for each integer k, there are at most g solutions to k = s1 + s2, si S; such sets are called Sidon sets if g = 2 a...
