In this paper we examine the problem of reconstructing a discrete two-dimensional set from its two orthogonal projection (H, V ) when the set satisfies some convexity conditions. We show that the… (More)

Completing the genome sequence of an organism is an important task in comparative, functional and structural genomics. However, this remains a challenging issue from both a computational… (More)

Bonin et al. (1993) recalled an open problem related to the recurrence relation verified by NSW numbers. The recurrence relation is the following: fn+l = 6f~ f~l , with jq = 1 and j~ = 7, and no… (More)

The problem of reconstructing finite subsets of the integer lattice from X-rays has been studied in discrete mathematics and applied in several fields like data security, electron microscopy, medical… (More)

The {em information diffusion} has been modeled as the spread of an information within a group through a process of social influence, where the diffusion is driven by the so called {em influential… (More)

We consider the following multi–level opinion spreading mo del on networks. Initially, each node gets a weight from the set {0, . . . , k− 1}, where such a weight stands for the individuals… (More)

Detecting on a graph the presence of the minimum number of nodes (target set) that will be able to “activate” a prescribed number of vertices in the graph is called the target set selection problem… (More)
