Electron-impact ionization cross sections for diatomic molecules are calculated in a configuration-average distorted-wave method. Core bound orbitals for the molecular ion are calculated using a single-configuration self-consistent-field method based on a linear combination of Slater-type orbitals. The core bound orbitals are then transformed onto a two-dimensional r , numerical lattice from wh...

A plate periodically bonded with piezoelectric patches on its surfaces is considered. The differential quadrature element method is used to solve the wave motion equation for the two-dimensional periodic structure. The method is very simple and easy to implement. Based on the method, band structures for in-plane wave propagating in the periodic piezoelectric plate are studied, from which the fr...

Abstract. In this article, we derive a series expansion of the multivariate normal probability integrals based on Fourier series. The basic idea is to transform the limits of each integral from hi to ∞ to be from −∞ to ∞ by multiplying the integrand by a periodic square wave that approximates the domain of the integral. This square wave is expressed by its Fourier series expansion. Then a Chole...

in this paper, we propose the least-squares method for computing the positive solution of a m  n fully fuzzy linear system (ffls) of equations, where m > n, based on kaman's arithmetic operations on fuzzy numbers that introduced in [18]. first, we consider all elements of coecient matrix are non-negative or non-positive. also, we obtain 1-cut of the fuzzy number vector solution of the n...

It is proven that a recently derived simple configuration-space wave equation for two spin-l/2 particles is equivalent to the Breit equation and to the Salpeter equation in first order perturbation theory. The wave equation is based on a simple quasipotential approximation. The potential in the equation is given by the Blankenbecler-Sugar correction series. The proof holds for an arbitrary comb...

Background: F-wave study, part of electrodiagnostic study, has had a controversial sensitivity in the diagnosis of lumbosacral radiculopathy. Objectives: We aimed to compare F wave parameters obtained from the tibial nerve of both extremities in patients with unilateral S1 radiculopathy. Materials and Methods: The study was done from March to September 2015 in the Electrodiagnostic laborator...
