A recent proof of NP-hardness of Euclidean sum-of-squares clustering, due to Drineas et al., <i>Machine Learning</i> 56, 9--33, 2004, is not valid. An altern...

Le texte qui suit est un chapitre du livre intitulé <i>Fourmis artificielles, des bases algorithmiques aux concepts et réalisations avancés</i>, Nicolas Monm...

Horizontal cooperation among franchisees is now a well-known reality in franchising, as exemplified by the growing number of franchisee associations and adve...

Let <img src="/cgi-bin/mimetex.cgi?G=(V,E)"> be a simple, undirected graph of order <img src="/cgi-bin/mimetex.cgi?n"> and size <img src="/cgi-bin/mimetex.cg...

We develop an approximate analysis of an arbitrary size homogeneous unreliable transfer line under a CONWIP discipline. Mean total work in process computatio...

This article addresses the problem of scheduling the replenishment of items to be delivered to multiple buyers from a single provider in order to minimize th...

The problem of reducing the bandwidth of a matrix consists of finding a permutation of rows and columns of a given matrix that keeps the non-zero elements in...

In this note we suggest a simple but efficient modification of the well-known Nelder-Mead (NM) simplex search method for unconstrained optimization. Instead ...

In this paper, we evaluate the impact of the wireless channel and physical layer parameters on the performance of VoIP traffic in IEEE 802.11g networks. The ...

We consider a duopolistic industry where the current sales of each firm is proportional to its goodwill stock. The evolution of the latter depends positivel...

The hexagon and heptagon with unit diameter and maximum sum of Euclidean distances between vertices are determined by enumerating diameter configurations, an...

This paper explores the dynamic properties of price-based policies in a model of competition between two jurisdictions. Jurisdictions invest over time in inf...

The peak load is the maximum daily processing capacity requirement in a warehouse, and is an alternative criterion for the storage location assignment proble...

The control synthesis problem for a class of linear time-delay systems with actuator saturation is investigated in this paper. The time delay is considered t...

Minimum sum-of-squares clustering consists in partitioning a given set of <i>n</i> points into <i>c</i> clusters in order to minimize the sum of squared dist...

In this paper we develop a model to analyze, in a dynamic framework, how countries join international environmental agreements (IEAs). In the model, where co...

The main purpose of this paper is to apply the True Notional Bond System (TNBS) proposed by Oviedo (2006) for the theoretical pricing of the Chicago Board ...

This paper deals with the stabilization of the class of continuous-time systems. A state feedback controller with delayed states is used to stabilize this cl...

This paper deals with the class of continuous-time singular linear systems with Markovian switching. Under full and partial knowledge of the jump rates of th...

We consider one of the most important issues for multinationals, the determination of transfer prices. To do so, we examine the example of a multinational co...
