In this paper, we consider testing the location parameter with multilevel (or hierarchical) data. A general family of weighted test statistics are introduced...

Let <i>G = (V,E)</i> be a graph with vertex set <i>V</i> and edge set <i>E</i>. The <i>k</i>-coloring problem is to assign a color (a number chosen in {1,.....

Many proposals have been made recently for goodness-of-fit testing of copula models. After reviewing them briefly, the authors concentrate on omnibus proced...

The problem retained for the ROADEF’99 international challenge was an inventory management problem for a car rental company. It consists in managing a given...

We discuss feature selection approaches within the context of linear programming models for discrimination, with special emphasis on a new interpretation an...

Using Clark-Ocone formula, explicit martingale representations for path-dependent Brownian functionals are computed. As direct consequences, explicit martin...

We develop a test of equality between two dependence structures estimated through empirical copulas. We provide inference for independent or paired samples....

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

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

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...

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

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 ...

Let <img src="/cgi-bin/mimetex.cgi?G = (V,E,w)"> be a graph with vertex and edge sets <img src="/cgi-bin/mimetex.cgi?V"> and <img src="/cgi-bin/mimetex.cgi?E...

This paper considers large shift scheduling problems with different shift start times and lengths, fractionable breaks and work stretch duration restrictions...

We analyze a territorial approach to deliver nursing home care services to a territory public health. We present the case of the CSSS assigned to Côte-des-N...

<p>Le système <i>AutoGraphiX (AGX1 et AGX2)</i> permet, parmi d’autres fonctions, la génération automatique de conjectures en théorie des graphes. Nous étud...

<p>Using the <i>AutoGraphiX 2</i> system, a systematic study is made on generation and proof of relations of the form</p> <center> $\underline{b}_n \leq ...

The aim of this paper is to present efficient algorithms for the detection of multiple targets in noisy images of a finite region. The algorithms are based ...

While convergence properties of many sampling selection methods can be proven to hold in a context of approximation of Feynman-Kac solutions using sequentia...
