This paper examines a network design problem that arises in the telecommunications industry. In this problem, communication between a gateway vertex and a number of demand vertices is achieved through a network of fiber optic cables. Since each cable has an associated capacity (bandwidth), enough capacity must be installed on the links of the network to satisfy the demand, using possibly differ...

Sur le plan urbanistique de la ville Kinshasa (capitale RDC), les colons, avaient prévu espaces verts pour un cadre vie urbain, verdoyant et permettant se détendre embellir ville. De 1960 à 1980, même politique publique a été respectée. Mais actuellement, avec l’explosion démographique, qui, jadis, faisaient fierté capitale RDC dans chaque commune, ont uns effacés carte géographique autres spol...

Von Neumann proved the minimax theorem (existence of a saddle-point solution to 2 person, zero sum games) in 1928. While his second article on the minimax theorem, stating the proof, has long been translated from German, his first announcement of his result (communicated in French to the Academy of Sciences in Paris by Borel, who had posed the problem settled by Von Neumann’s proof) is translat...

Le recours à l'anticipation pour repenser les défis écologiques n'a rien d'étonnant dans une littérature destinée jeunesse que l'on cherche préparer l'avenir. Aussi serait-il logique dystopies écrites au XXIe siècle Espagne préoccupée par l'expansion tentaculaire de la ville et désertification des campagnes invitent réinventer relation ville/campagne. Nous tenterons voir ici si elles y sont par...

Time-frequency representations have been of great interest in the analysis and classification of non-stationary signals. The use of highly selective transformation techniques is a valuable tool for obtaining accurate information for studies of this type. The Wigner-Ville distribution has high time and frequency selectivity in addition to meeting some interesting mathematical properties. However...

BACKGROUND Analysis of heart rate variation (HRV) has become a popular noninvasive tool for assessing the activities of the autonomic nervous system (ANS). HRV analysis is based on the concept that fast fluctuations may specifically reflect changes of sympathetic and vagal activity. It shows that the structure generating the signal is not simply linear, but also involves nonlinear contributions...
