Based on credibilistic value-at-risk (CVaR) of regularfuzzy variable, we introduce a new CVaR reduction method fortype-2 fuzzy variables. The reduced fuzzy variables arecharacterized by parametric possibility distributions. We establishsome useful analytical expressions for mean values and secondorder moments of common reduced fuzzy variables. The convex properties of second order moments with ...

Moment functions are widely used in image analysis as feature descriptors. Compared to geometric moments, orthogonal moments have become more popular in image analysis for their better representation capabilities. In comparison to continuous orthogonal moments discrete orthogonal moments provide a more accurate description of the image features. This paper compares the performance of discrete o...

In this paper, we give an analytic proof of the asymptotic behavior moments characteristic polynomials random symplectic and orthogonal matrices. We therefore obtain alternate, integral expressions for leading order coefficients previously found by Assiotis, Bailey Keating. also discuss conjectures Keating corresponding [Formula: see text]-functions with symmetry. Specifically, show that these ...

This paper proposes an overview of computer structural analysis and reinforcement calculation techniques reinforced concrete ribbed slabs that are used in Ukraine. It considers the fundamental hypotheses assumptions these analyzes possibility implementation building codes’ requirements into automated calculations. Numerical experiments confirm existence a relationship between normal stress dist...

Taking t at random, uniformly from [0,T], we consider the kth moment, with respect to t, of random variable corresponding 2?th moment ?(1/2+ix) over interval x?(t,t+1], where ?(s) is Riemann zeta function. We call these ‘moments moments’ function, and present a conjecture for their asymptotics, when T??, integer k,?. This motivated by comparisons results moments characteristic polynomials unita...

In this paper, we establish some recurrence relations for single and product moments of generalized order statistics from pth order exponential distribution. Further the results are deduced for the recurrence relations of record values and ordinary order statistics and using a recurrence relation for single moments we obtain characterization of pth order exponential distribution.

Abstract In those cases where architectural requirements are a priority, hollow sections the preferred solution. Considering cross‐sectional classes 1 and 2, plastic design is possibility that preferable for both economic ecological reasons. technical standards literature, wide variety of interaction formulae can be found. However, in most cases, information about their accuracy not provided. t...

Received: October 04 2016; Accepted: October 26, 2016; Published: November 01, 2016 In recent years, plastic surgery has been gaining prominence and its techniques presenting important improvements. With the increasing number of plastic surgeries and the proliferation of information about them, we also noticed that is necessary to offer these patients in new ways to experience the postoperative...
