The Smart Grid (SG) is conceived as the evolution of the current electrical grid representing a big leap in terms of efficiency, reliability and flexibility compared to today's electrical network. To achieve this goal, the Wireless Sensor Networks (WSNs) are considered by the scientific/engineering community to be one of the most suitable technologies to apply SG technology to due to their low-...

Baxters's Q-operators for the simplest q-deformed model. Abstract In the present paper we describe the procedure of the Q-operators construction for the q-deformed model, described by the Lax operator, which is important to formulate the Bethe ansatz for the Sin-Gordon model. This Lax operator can also be considered as some massless limit of the Lax operator of SG model. We constructed two R op...

Let H∞(D) denote the algebra of bounded analytic functions on the open unit disc in the complex plane. For a function g ∈ L∞(D), the Hankel-type operator Sg is defined by Sg(f) = gf +H∞(D). We give here an overview of the study of the symbol of the Hankel-type operator, with emphasis on those symbols for which the operator is compact, weakly compact, or completely continuous. We conclude with a...

Let H be the general, reduced Heisenberg group. Our main result establishes the inverse-closedness of a class of integral operators acting on Lp(H), given by the off-diagonal decay of the kernel. As a consequence of this result, we show that if α1I+Sf , where Sf is the operator given by convolution with f , f ∈ Lv(H), is invertible in B(Lp(H)), then (α1I + Sf )−1 = α2I + Sg, and g ∈ Lv(H). We p...

Software defined networks (SDN) has been proposed to monitor and manage the communication networks globally. SDN revolutionized the way the communication network managed previously. By segregating the control plane from the data plane, SDN helps the network operators to manage the network flexibly. Since smart grid heavily relies on communication networks, therefore, SDN has also paved its way ...

on the basis of discourse grammar (dg), this study investigates the expression of  yæ'ni in persian. the term was originally borrowed from arabic and has undergone the process of grammaticalization. it exhibits different pragmatic functions to characterize changes involved in the evolution of this discourse marker. the study suggests that grammaticalization of yæ'ni should be analyzed...

Abstract. The competition between spin glass (SG), antiferromagnetism (AF) and Kondo effect is studied here in a model which consists of two Kondo sublattices with a gaussian random interaction between spins in differents sublattices with an antiferromagnetic mean Jo and standard deviation J . In the present approach there is no hopping of the conduction electrons between the sublattices and on...
