Adaptive optics (AO), now installed on all the astronomical ground-based telescopes, make it possible to overcome angular resolution limitations imposed by atmospheric turbulence. This article presents state-of-the-art in field of applications, and shows how adaptive has revolutionized observation over last twenty years, overcoming countless scientific technical challenges. Finally, we present ...

Dynamic load balancing and migration are two main mechanisms to increase system throughput and to reduce application response time. These mechanisms become very complex (and time consuming) to manage, when the computing system increases in scale and heterogeneity. We have proposed the Territory Model in 14] that separates the system in Computational Domains, where each domains manage its resour...

In [3] M. Luby and C. Rackoff have proved that 3-round random Feistel schemes are secure against all adaptative chosen plaintext attacks when the number of queries is m ¿ 2. Moreover, 4-round random Feistel schemes are also secure against all adaptative chosen plaintext and chosen ciphertext attacks when m ¿ 2. It was shown later that these bounds are tight for 3 and 4 rounds (see [9] or [1]). ...

Using a new-generation open-circuit calorimeter capable of monitoring the cost of activity, and thereby both the real thermic effect of feeding (TEF) and basal metabolism in free-moving freely-feeding rats, we have reassessed the proposal that when food intake is restricted an adaptative reduction in energy expenditure participates in the achievement of energy balance. Total energy expenditure,...

| Nearest Neighbor rules are widely used non-parametric classiiers in Pattern Recognition. The main drawbacks of these rules are related to the computational eeort required. In that sense, some techniques have been proposed to select a reduced and representative reference set from the original training set. Adaptative learning techniques may be used successfully to reduce the reference set size...

IAbstract—Glucose is a CDCL solver heavily based on Minisat, with a special focus on removing useless clauses as soon as possible, and an original restart scheme. Syrup is the parallel version of Glucose, with a lazy clauses exchanges policy. In the 2015 version of these solvers, we proposed a genuine version and an “adaptative” version of each of them. The adaptative versions use a set of part...

RÉSUMÉ. Cet article présente un environnement de résolution de contraintes (CSP) musicales, basé sur le langage visuel OpenMusic. Nous présentons notamment une implémentation d’un algorithme de recherche locale, appelé recherche adaptative, dans le domaine musical. La recherche adaptative reprend le principe de résolution par optimisation d’une fonction de coût, mais en affinant la notion de co...

The fashion and increase of consumers cultural is an important problem. This paper studies the effective Socio-Cultural Factors on the fashion trends among the girl student’s in Andimeshk. About 200 girls in Andimeshk (South west of Iran) were randomly chosen. The research method was survey and correlation with questionnaire. The data were analyzed through SPSS package along with Pearson coeffi...
