The maximization through signal design of the symmetric capacity of CDMA systems with optimal and minimum mean-square error decision feedback (MMSE-DF) decoding is considered. In particular, lower bounds on maximum symmetric capacity (and the signal set that achieves them) are derived for the two decoders. A common sufficient condition is obtained for both decoders under which the signal design...

Résumé. Les Dépendances Fonctionnelles Conditionnelles (DFC) ont été introduites en 2007 pour le nettoyage des données. Elles peuvent être considérées comme une unification de Dépendances Fonctionnelles (DF) classiques et de Règles d’Association (RA) puisqu’elles permettent de spécifier des dépendances mixant des attributs et des couples de la forme attribut/valeur. Dans cet article, nous trait...

We define a quantitative semantics for evaluating the strength of arguments in Bipolar Argumentation frameworks (BAFs) by adapting the DiscontinuityFree QuAD (DF-QuAD) algorithm previously used for evaluating the strength of arguments in Quantitative Argumentation Debates (QuAD) frameworks. We study the relationship between the new semantics and some existing semantics for other argumentation f...

In this paper, we present a new approach for solving absolute value equation (AVE) whichuse Levenberg-Marquardt method with conjugate subgradient structure. In conjugate subgradientmethods the new direction obtain by combining steepest descent direction and the previous di-rection which may not lead to good numerical results. Therefore, we replace the steepest descentdir...

The role of the nuclear medicine has changed, from the early days when it was the only alternative to x-rays, to the present, when nuclear images are interpreted in light of specific metabolic processes, not anatomy. The development of specific receptor targeting radiopharmaceuticals, markers of viability using PETor SPECT, analogues of neurotransmitters etc., have placed the nuclear medi...
