Random access is a multiple access communication protocol where the users simultaneously communicate with a base station (BS) in an uncoordinated fashion. In this work, we consider the problem of multiuser detection in a random access bandwidth request context. We propose an enhanced random access scheme where the fixed/low-mobility machineto-machine (M2M) devices pre-equalize their random acce...

Algorithms combining multi-view information are known to exponentially quicken classification, and have been applied to many fields. However, they lack the ability to mine most discriminant information sources (or data types) for making predictions. In this paper, we propose an algorithm based on boosting to address these problems. The proposed algorithm builds base classifiers independently fr...

With the purpose of studying new biologically active substances in spring forage pea, during the 2007-2009 a two-factor field trial was carried out in IFC, Pleven. The biologically active substances Atonic (growth stimulant) – 0.06 l/da, Masterblend (combined leaf fertilizer) – 160 g/da and Confidor 70 WG (700 g/kg imidacloprid) – 15 g/da (an insecticide) were applied once (at the stages of bud...

Learning in many multi-agent settings is inherently repeated play. This calls into question the naive application of single play Nash equilibria in multi-agent learning and suggests, instead, the application of give-andtake principles of bargaining. We modify and analyze a satisficing algorithm based on (Karandikar et al., 1998) that is compatible with the bargaining perspective. This algorithm...

acinetobacter lwoffii, an important nosocomial pathogen, is a gram-negative aerobic bacillus that is a component of the normal flora on the skin, oropharynx, and perineum of about 20-25% of healthy individuals. we herein present a case of a 66-year-old man with combined mitral and aortic valve endocarditis associated with multi-drug resistance acinetobacter lowffii bacteremia.

there are many benefits for coordination of multiple suppliers when single supplier cannot satisfy buyer demands.  in addition, buyer needs to purchase multiple items in a real supply chain. so, a model that satisfies these requests has many advantages. we extend the existing approaches in the literature that assume all suppliers need to be put on a common replenishment cycle and each supplier ...

in this paper, we study the multi-depot vehiclerouting problem with inter-depot routes, in which the vehicles can replenish atintermediate depots. vehicles leave the origin depot with load on-board andserve customers until out of load. they may visit an intermediate depot toreplenish and finally return to the origin depot, completing their route. weinitiate a mathematical mixed integer programm...

Le volume des données géographiques devient de plus en plus important et leur utilisation étendue à différents domaines, d’où le besoin de fouiller dans ces données géographiques. Ces données informent sur la position (les coordonnées) et la forme (point, ligne ou surface) d’objets. Ainsi, l’utilisation des algorithmes de fouille de données devient plus complexe, surtout quand il s’agit d’élabo...

We explore the performance of MMSE multiuser receivers in wireless systems where the signatures are modeled as random and take values in complex space. First we study the conditional distribution of the output multiple-access interference (MAI) of the MMSE receiver. By appealing to the notion of conditional weak convergence, we nd that the conditional distribution of the output MAI, given the s...
