This paper deals with a crack problem for a nearly circular shape in plane elasticity. The problem of ¯nding the result- ing shear stress can be written in a single hypersingular integral equation form. By making a suitable ...

Mass transfer is a process that occurs in liquid-liquid extraction column. One of the equipment uses for the liquid-liquid extraction is the rotating disc contactor (RDC) column. In order to determine the concentration of ...

We investigate the properties of modulation instability in the Salerno equation in quasi-one dimension in Bose-Einstein condensate (BEC). We analyze the regions of modulation instability of nonlinear plane waves and determine ...

In this paper, we propose a new multi-step quasi- Newton method for solving unconstrained optimization problem. Our new gradient method is a in the frame of Barzilai and Borwein method. A multi step method is used to ...

A two dimensional multi Fourier-component magnetic field is moved along a channel filled with an incompressible, electrically conducting viscous fluid at a time-dependent velocity of a sinusoidal type at finite magnetic ...

Wavelet regression has been proven to be highly effective at reconstructing most kinds of regression curves. However, this estimator suffers from boundary problems caused by the application of the wavelet transformation ...

Many methods and procedures have been developed and proposed to overcome the estimation problem in spatial modeling, for example, by defining classes of models called separable models and the unilateral models. A special ...

Car cabin interior vibration and acoustical comfort are factors which are normally considered by customers when purchasing a vehicle. Basically, a vehicle with much vibration will at the same time have an uncomfortable ...

It is well-known that eigenvalues of a symmetric linear operator on an n-dimensional real vector space are all real. In general, for a symmetric tensor field of type (1, 1) on a connected n-dimensional Riemannian manifold ...

In crisp topologies space, there are three selection principles that have been introduced such as S1(A, B), Sfin(A, B) and Ufin (A, B). In this paper, consider A or B as fuzzy open sets which have certain fuzzy ...
