Sliding mode stress intensity factor for a nearly circular crack subject to shear load
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Molarity model of mass transfer for extraction in rotating disc contactor (RDC) column
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Modulation Instability in Bose-Einstein condensate
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
A new multi-step gradient method for optimization problem
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Effects of time-dependent magnetic field velocity of sinusoidal type at finite Rm in a closed channel
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Polynomial wavelet regression with boundary correction
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Examining the properties of the estimators of the spatial unilateral autoregressive model by bootstrapping
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Optimization model of noise and vibration in passenger car cabin on pavement road
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Eigenvalue functions of symmetric tensorfields on Riemannian manifolds
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
Fuzzy covering space and fuzzy selection principle
(Universiti Malaysia Perlis (UniMAP), 2010-06-02)
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 ...
