‎ranking fuzzy numbers is generalization of the concepts of order, and class, and so have fundamental applications. moreover, deriving the final efficiency and powerful ranking are helpful to decision makers when solving fuzzy problems. selecting a good ranking method can apply to choosing a desired criterion in a fuzzy environment. there are numerous methods proposed for the ranking of fuzzy n...

Recently, Sarier [1] proposed an efficient biometric Identity Based Encryption (IBE) scheme called BIO-IBE using the Sakai Kasahara Key Construction and prove its security in the random oracle model based on the well-exploited k-BDHI computational problem. Despite its efficiency compared to other fuzzy IBE systems implemented for biometric identities, BIO-IBE is not secure against a new type of...

A novel fuzzy-logic-based control for vehicle-active suspension is suggested. The vehicle vibration and disturbance are reduced considerably with a fuzzy logic controller, to enhance comfort in riding faced with uncertain road terrains. A quarter-car active suspension system is controlled to reduce the vertical acceleration to a level of, that of, a hypothetical reference model. A new look-up t...

Résumé. Dans cet article, nous nous intéressons à Fuzzy C-Means (FCM), une technique très connue pour la classification floue. Nous proposons un algorithme efficace basé sur la programmation DC (Difference of Convexe functions) et DCA (DC Algorithm) pour résoudre ce problème. Les expériences numériques comparatives avec l’algorithme standard FCM sur les données réelles montrent la robustesse, l...

   Background & Objective: Cardiovascular disease (CVD) is the main cause of morbidity and mortality in most countries. By identifying the population attributable risk (PAR) of the main risk factors of CVDs, the overall effect of various exposures on a population can be determined; the findings could be used in CVD prevention. The present study aimed to explore the PAR of some factors, includin...

Résumé. Dans cet article nous proposons une approche originale basée sur les techniques de data mining pour l’extraction des connaissances par fusion floue de données. Cette approche présente une nouvelle architecture de fusion de données basée sur la théorie possibiliste pour la segmentation d’une cible à partir de plusieurs sources d’images. Le processus de fusion est décomposé en trois phase...

mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. the purpose of this study was to determine the degree of improvement in occlusion in patients with bolton discrepancy treated by one lower incisor extraction using peer assessment rating index (par indexes).pre and post treatment dental c...

La segmentation est un facteur clef de la recherche d’images par le contenu (CBIR). La couleur, la texture et la forme sont les principaux attributs visuels en CBIR (Flickner et al. 1995, Carson et al. 1999). Ils ne garantissent pas des réponses assez sûres. On les complète donc par des relations spatiales entre objets, supposant que l’image est organisée (Chang et al. 1987, Gudivada et Raghava...

In recent years, expansion of power system is not as par the need of power demand which has increased substantially [3]. As a consequence, existing transmission lines are heavily loaded and the stability of the system ecomes a power transfer-resisting factor. Flexible AC transmission systems (FACTS) controllers have been mainly designed to solve such type of power system steady state controllin...
