Abstract— Online social networks (e.g. Facebook, Twitter, Youtube) provide a popular, cost-effective and scalable framework for sharing user-generated contents. This paper addresses the intrinsic incentive problems residing in social networks using a game-theoretic model where individual users selfishly trade off the costs of forming links (i.e. whom they interact with) and producing contents p...

This paper presents the three topologies of three-phase four-wire DSTATCOM for reduction of harmonics, reactive power compensation, increasing power factor, which occur due to a nonlinear load, environment problem and polluted grid. The performances of the above topologies have been compared for the magnitude of source current, power factor improvement, DC-link voltage regulation, and total har...

Since the pioneering efforts of Duwez and co-workers in 1965, when a solid amorphous phase palladium-silicon (a-PdSi) was obtained vicinity eutectic concentration, much work has been done. However, some points related to atomic structures remain be systematized. In this work, 8 Pd100-cSic alloys (c = 2.5, 5, 10, 13.34, 15, 17.5, 20, 22 at%) are generated by molecular dynamics ab initio simulati...

Given any preorder on a finite set X, we present an algorithm to construct a partial pseudometric p on X which generates in the sense that a b if and only if p(a, b) ≤ p(a, a). The specialization topology generated by agrees with the topology generated by the partial pseudometric p-balls, and consequently any topology on X is generated by a partial pseudometric. AMS Subject classification: 54A0...

Current network modeling practices usually assess the network performance at specified time interval, i.e. every 5 or 10 years time horizon. Furthermore, they are usually based on partially predictable data, which are being generated through various stochastic procedures. In this research, a new quantitative based methodology which combines combinatorial optimization modeling and transportation...

Let $M$ and $N$ be two finitely generated graded modules over a standard graded Noetherian ring $R=bigoplus_{ngeq 0} R_n$. In this paper we show that if $R_{0}$ is semi-local of dimension $leq 2$ then, the set $hbox{Ass}_{R_{0}}Big(H^{i}_{R_{+}}(M,N)_{n}Big)$ is asymptotically stable for $nrightarrow -infty$ in some special cases. Also, we study the torsion-freeness of graded generalized local ...

ur aim of this  paper  is  to introduce the concept of $L$-double fuzzy rough sets in whichboth constructive and axiomatic approaches are used. In constructive approach, a pairof $L$-double fuzzy lower (resp. upper) approximation operators is defined  and the basic properties of them  are studied.From the viewpoint of the axiomatic approach, a set of axioms is constructed to characterize the $L...
