We propose a non-interactive zero knowledge pairwise multiset sum equality test (PMSET) argument in the common reference string (CRS) model that allows a prover to show that the given committed multisets Aj for j ∈ {1, 2, 3, 4} satisfy A1 ] A2 = A3 ] A4, i.e., every element is contained in A1 and A2 exactly as many times as in A3 and A4. As a corollary to the PMSET argument, we present argument...

We investigate definitions of security for previously proposed schemes for electronic cash and strengthen them so that the bank does need to be trusted to the same extent. We give an experiment-based definition for our stronger notion and show that they imply security in the framework for Universal Composability. Finally we propose a scheme secure under our definition in the common reference st...

Abstract. For any continuous zero-mean random variable (r.v.) X, a reciprocating function r is constructed, based only on the distribution of X, such that the conditional distribution of X given the (at-most-)two-point set {X, r(X)} is the zero-mean distribution on this set; in fact, a more general construction without the continuity assumption is given in this paper, as well as a large variety...

‎The purpose of this paper is to introduce a new mapping for a finite‎ ‎family of accretive operators and introduce an iterative algorithm‎ ‎for finding a common zero of a finite family of accretive operators‎ ‎in a real reflexive strictly convex Banach space which has a‎ ‎uniformly G^ateaux differentiable norm and admits the duality‎ ‎mapping $j_{varphi}$‎, ‎where $varphi$ is a gauge function ...

A new design concept for a common-mode signal suppression circuit for a balanced-type filter has been investigated. The degradation mechanism of the balance characteristics was studied. The degradation is caused by the common-mode signals combined with the differentialmode signals in the balanced terminals. The concept employed is the reduction of the common-mode signal using a common-mode sign...

A modular multilevel converter (MMC) can generate different common-mode voltage (CMV) values due to the high-frequency changing of switching state under various modulation strategies. The dv/dt will produce current in equivalent loop ground, which affect insulation and shorten life equipment. To eliminate effect on MMC operation, a elimination strategy (0CMV-SVPWM) is proposed for five-level sp...

in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

The performance of the units is defined as the ratio of the weighted sum of outputs to the weighted sum of inputs. These weights can be determined by data envelopment analysis (DEA) models. The inputs and outputs of the related (Decision Making Unit) DMU are assessed by a set of the weights obtained via DEA for each DMU. In addition, the weights are not generally common, but rather, they are ve...
