Résumé— La radio cognitive (RC) évolue dans des domaines aussi différents que variés, l’un de ces domaines applicatifs est les réseaux. Dans ce papier, nous proposons une nouvelle approche de la RC qui vise à gérer la transmission de la vidéo conférence d’un utilisateur secondaire (SU) pour différentes classes gérer par un utilisateur primaire (PU) en possession d’une licence sur le spectre et ...

This paper generalizes the traditional statistical concept of prediction intervals for arbitrary probability density functions in highdimensional feature spaces by introducing significance level distributions, which provides interval-independent probabilities for continuous random variables. The advantage of the transformation of a probability density function into a significance level distribu...

Understanding the factors that affect users’ acceptance of e-learning systems is critical for the success of adopting an e-learning system. Drawing upon the Construal Level Theory and the Technology Acceptance Model, we propose that the users’ construal level of the e-learning system would interact with users’ perceptions of the system (i.e., the perceived ease of use [PEoU] and perceived usefu...

Information technology is widely used as a media monitor various activities. In this study, the authors will utilize IT to monitor the Rural Infrastructure Development Program (PPIP). PPIP is a program of community development at the village level in the framework of the provision of basic infrastructure in rural settlements carried out by the Directorate General of Human Settlements Ministry o...

Image-based approaches based on one-class classifiers are presented. The information is extracted with a feature-based representation and recognized by using an ensemble of one-class classifiers. The features extracted by ‘‘FingerCode’’ are used to capture the ridge strength. The experiments show that our system outperforms the standard ‘‘FingerCode’’ recognition method. r 2006 Elsevier B.V.

Every set of ordinals of cardinality κ in a Prikry extension with a measure over κ contains an old set of arbitrary large cardinality below κ, and, actually, it can be split into countably many old sets. What about sets bigger cardinalities? Clearly, any set of ordinals in a forcing extension of a regular cardinality above the cardinality of the forcing used, contains an old set of the same car...
