This paper presents a novel topology of single-phase multilevel inverter for low and high power applications. It consists of polarity (Level) generation circuit and H Bridge. The proposed topology can produce higher output voltage levels by connecting dc voltage sources   in series and parallel. The proposed topology utilizes minimum number of power electronic devices which helps in reduction o...

Let M be a von Neumann algebra, φ a faithful normal state and denote by M the fixed point algebra of the modular group of φ. Let UM and UMφ be the unitary groups of M and M. In this paper we study the quotient Uφ = UM/UMφ endowed with two natural topologies: the one induced by the usual norm of M (called here usual topology of Uφ), and the one induced by the pre-Hilbert C∗-module norm given by ...

فرض کنیم a یک حلقه ی یکدار کاهش یافته (فاقد عنصر پوچ توان غیر بدیهی)باشد. خانواده تمام ایدآلهای اول سره از a را با spec(a)و خانواده تمام ایدآلهای اول مینیمال درa را باmin(a) نمایش می دهیم. مطالعات خوبی در مورد توپولوژی هسته غلافی (hull-kernel topology) یا همان توپولوژی زاریسکی،روی min(a)انجام شده است.به عنوان مثال این توپولوژی دارای پایه ای از زیرمجموعه های بستباز است. در این مقاله بر روی min...

In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. Also, we prove that  right and product stabilizers are filters and if they are ...

Generalising Nachbin's theory of ``topology and order'', in this paper we   continue the study of quantale-enriched categories equipped with a compact   Hausdorff topology. We compare these $V$-categorical compact Hausdorff spaces   with ultrafilter-quantale-enriched categories, and show that the presence of a   compact Hausdorff topology guarantees Cauchy completeness and (suitably   defined) ...

in this paper, a new circuit is proposed for step-up z-source inverter based on qzsi (quasi-z-source inverter). the proposed topology inherits all advantages of the conventional topology. the proposed topology in comparison with conventional topology reduces the st (shoot-through) duty cycle by over 25% at the same voltage boost factor. theoretical analysis of the proposed qzsi in the st and no...

A closed Riemannian n-manifold M with Ricci M > n 1 has diameter < 7r ([M]), and equality holds only if M is isometric to the unit sphere S ~ ([Cn]). Given these results, it is natural to ask whether M is diffeomorphic to S n if the diameter of M is almost 7r. This question was answered negatively by Anderson and Otsu, who showed that even the topology of such a space can be different from the ...

A topology is de Groot dual of another topology, if it has a closed base consisting of all its compact saturated sets. Until 2001 it was an unsolved problem of J. Lawson and M. Mislove whether the sequence of iterated dualizations of a topological space is finite. In this paper we generalize the author’s original construction to an arbitrary family instead of a topology. Among other results we ...

let  be a graded ring and  be a graded -module. we define a topology on graded prime spectrum  of the graded -module  which is analogous to that for , and investigate several properties of the topology.

in this paper, a pointwise pseudo-metric function on the l-realline is constructed. it is proved that the topology induced by this pointwisepseudo-metric is the usual topology.
