This paper presents the design and dimensioning optimization of a novel optical network structure, called the PetaWeb, having a total capacity of several Pb...

A weighted spatial median is proposed for the multivariate location problem with cluster correlated data. Its limiting distribution is derived under mild co...

The multidimensional scaling (MDS) aims at finding coordinates for a set of <i>n</i> objects in a (low) <i>q</i> dimensional space that best fits dissimilar...

We investigate the common practice of estimating the dependence structure between CDS prices on multi-name credit instruments by the dependence structure of ...

The AutoGraphiX research program led to a new type of application of metaheuristics in graph theory, <i>i.e.</i>, finding conjectures on graph invariants by...

Using the AutoGraphiX 2 system (AGX2), we study relations between graph invariants of the form <img src="/cgi-bin/mimetex.cgi?lbn \leq R \oplus i \leq ub...

Colour image quantization is a data compression technique that reduces the total set of colours in an image to a representative subset. This problem is expr...

This paper proposes new tests of randomness for innovations of a large class of time series models. These tests are based on functionals of empirical proces...

This paper deals with the problem of determining optimal reservoir daily operating policy over a one-year period. This problem is stochastic since the daily...

We consider the problem of separating two sets of points in an Euclidean space with a hyperplane that minimizes the sum of <i>L_p</i>-norm distanc...

In the integrated aircraft routing, crew scheduling and flight retiming problem, a minimum-cost set of aircraft routes and crew pairings must be constructed...

This paper shows that the important result obtained in a static marketing channel, namely, that the manufacturer can coordinate the channel through a two-pa...

<p> We consider an infinite-horizon differential game played by two direct marketers. Each player controls the number of emails sent to potential customers...

Past studies have shown the unstability of unstructured peer-to-peer networks, in particular Gnutella. Because of this unstability, queries in these network...

We propose a general setting for pricing single-name knock-out credit derivatives. Examples include Credit Default Swaps (CDS), European and Bermudan CDS op...

We consider the problem of orienting the edges of a graph so that the length of a longest path in the resulting digraph is minimum. As shown by Gallai, Roy ...

In this paper, we consider scheduling problems on a single machine in a sequence dependent setup environment. We introduce for these problems several integer...

The Cox proportional hazards model has become the model of choice to use in analyzing the effects of covariates on survival data. However, this assumption ha...

In this paper, we study the problem of determining the capacity requirements for applications that require QoS guarantees. We consider three kinds of source ...

This work shows how disjunctive cuts can be generated for a bilevel linear programming problem (<i>BLP</i>) with continuous variables. First, a brief summar...
