in this paper the concept of metacompactness in l-topologicalspaces is introduced by means of point finite families of l-fuzzy sets. thisfuzzy metacompactness is a natural generalization of lowen fuzzy compactness.further a characterization of fuzzy metacompactness in the weakly inducedl-topological spaces is also obtained.

In this paper we show that, after completing in the $I$-adic topology, Turaev cobracket on vector space freely generated by closed geodesics a smooth, complex algebraic curve $X$ with quasi-algebraic framing is morphism of mixed Hodge structure. We combine results previous Goldman bracket to construct torsors solutions Kashiwara–Vergne problem all genera. The so constructed form torsor under pr...

This paper proposes a flat bottom driving method for switched reluctance motor (SRM) by using full-bridge power converter. Based on ring structure, an SRM is able to be driven inverter. With the proposed topology, adding harmonics in sinusoidal current waveform from space vector PWM (SVPWM) method, can generated SRM. According theoretical analysis and calculation, reduces copper loss, compared ...

In this paper, for topology optimization of double layer grids, an efficient optimization method is presented by combination of Imperialist Competitive Algorithm (ICA) and Gravitational Search Algorithm (GSA) which is called ICA-GSA method. The present hybrid method is based on ICA but the moving of countries toward their relevant imperialist is done using the la...

This paper introduces a novel two transistors forward topology employing a z-source to achieve ZVZCS and power transformer resetting for various applications. Comparing with the forward converter, this topology has the advantage of displaying ZCS condition with an added Z-Source and no additional switches when the switches turn on, and that ZVS condition happens when the switches turn off. Duty...

we consider the transitive linear maps on the operator algebra $b(x)$for a separable banach space $x$. we show if a bounded linear map is norm transitive on $b(x)$,then it must be hypercyclic with strong operator topology. also we provide a sot-transitivelinear map without being hypercyclic in the strong operator topology.

With social networking sites providing increasingly richer context, user-centric service creation is expected to follow a similar growth with User-Generated Content. The what-is-often-called User Generated Services paradigm calls for efficient yet scalable solutions for optimally placing service facilities. Typically seen as an instance of the facility location problem, service placement has be...

There is no method to determine the optimal topology for multi-layer neural networks for a given problem. Usually the designer selects a topology for the network and then trains it. Since determination of the optimal topology of neural networks belongs to class of NP-hard problems, most of the existing algorithms for determination of the topology are approximate. These algorithms could be class...

Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...

We prove some simple properties of the power series ring R = Kx 1 ; x 2 ; x 3 ; : : : ]] on a countably innnite number of variables over a eld K, and of the subring R 0 generated by all homogeneous elements in R. By means of a certain decreasing ltration of ideals, which are kernels of the \truncation homomorphisms" n : R 0 ! Kx 1 ; : : : ; x n ], we endow R 0 with a topology, and show that wit...
