This paper presents a highly efficient approach for bounding the responses and probability of failure nonlinear models subjected to imprecisely defined stochastic Gaussian loads. Typically, such computations involve solving nested double-loop problem, where propagation aleatory uncertainty has be performed each realization epistemic parameters. Apart from near-trivial cases, computation is gene...

breaking bad news is one of the most burdensome tasks physicians face in their everyday practice. it becomes even more challenging in the context of hiv + patients because of stigma and discrimination. the aim of the current study is to evaluate the quality of giving hiv seroconversion news according to spikes protocol. numbers of 154 consecutive hiv + patients from imam khomeini hospital testi...

pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. in developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies w...

For given symbol in the n-th Milnor K-group modulo prime l we construct a splitting variety with several properties. This variety is lgeneric, meaning that it is generic with respect to splitting fields having no finite extensions of degree prime to l. The degree of its top Milnor class is not divisible by l2, and a certain motivic cohomology group of this variety consists of units. The existen...

in this paper, we consider the boundedness of the libera operator on dirichlet spaces in terms of the schur test. moreover, we get its point spectrum and norm.

Let ‎X be an ‎‎n-‎‎‎‎‎‎square complex matrix with the ‎Cartesian decomposition ‎‎X = A + i ‎B‎‎‎‎‎, ‎where ‎‎A ‎and ‎‎B ‎are ‎‎‎n ‎‎times n‎ ‎Hermitian ‎matrices. ‎It ‎is ‎known ‎that ‎‎$Vert X Vert_p^2 ‎leq 2(Vert A Vert_p^2 + Vert B Vert_p^2)‎‎‎$, ‎where ‎‎$‎p ‎‎geq 2‎$‎ ‎and ‎‎$‎‎Vert . Vert_p$ ‎is ‎the ‎Schatten ‎‎‎‎p-norm.‎ ‎‎ ‎‎In this paper‎, this inequality and some of its improvements ...

In this paper‎, ‎using the discrete Fourier transform in the finite-dimensional Hilbert space C^n‎, ‎a class of nonRieszable equal norm tight frames is introduced ‎and‎ using this class, a bound for Fiechtinger Conjecture is presented. By the Fiechtinger Conjecture that has been proved recently, for given A,C>0 there exists a universal constant delta>0 independent of $n$ such that every C-equal...

In this paper we address symmetry on combinatorial problems by following the approach of imposing additional symmetry-breaking constraints. Differently from other works in the literature, we attack the problem at the specification level. In fact, sometimes symmetries on specifications can be very easily detected, and symmetry-breaking formulae generated. We give formal definitions of symmetries...

Many constraint problems exhibit dominance relations which can be exploited for dramatic reductions in search space. Dominance relations are a generalization of symmetry and conditional symmetry. However, unlike symmetry breaking which is relatively well studied, dominance breaking techniques are not very well understood and are not commonly applied. In this paper, we present formal definitions...
