A Magnetic Transport Middle Eastern Positron Beam
(
Elsevier
, 2008 , Article)
A magnetically guided slow positron beam is being constructed at Qatar University and is currently being optimised for regular operation. This is the first positron beam in the Middle East, as well as being the first Arabic ...
New tellurite glass: Optical properties
(
Elsevier
, 2008 , Article)
The refractive index and UV spectra of the quaternary tellurite glass system of the form 80TeO2-5TiO2-(15 - x) WO3-xAnOm where AnOm is Nb2O5, Nd2O3 and Er2O3, x = 0.01, 1, 3 and 5 mol% for Nb2O5 and x = 0.01, 0.1, 1, 3, 5 ...
Homotopy analysis method for fractional IVPs
(
Elsevier
, 2007 , Article)
In this paper, the homotopy analysis method is applied to solve linear and nonlinear fractional initial-value problems (fIVPs). The fractional derivatives are described by Caputo’s sense. Exact and/or approximate analytical ...
Numerical comparison of methods for solving a special fourth-order boundary value problem
(
Elsevier Inc.
, 2007 , Article)
In this paper, we implement relatively new analytical techniques, the differential transform method, Adomian decomposition, and homotopy perturbation method, for solving a fourth-order boundary value problem. In these ...
On stability of equilibrium points in nonlinear fractional differential equations and fractional Hamiltonian systems
(
Wiley Periodicals, Inc.�
, 2014 , Article)
In this article, a brief stability analysis of equilibrium points in nonlinear fractional order dynamical systems is given. Then, based on the first integral concept, a definition of planar Hamiltonian systems with fractional ...
An efficient technique for finding the eigenvalues of fourth-order Sturm–Liouville problems
(
Elsevier
, 2009 , Article)
In this paper, we will develop a numerical technique for finding the eigenvalues of fourth-order non-singular Sturm–Liouville problems. We used the variational iteration methods as a basis for this technique. Numerical ...
Complex-impedance response of an Ag/TeO2-V2O5/Ag structure
(
Elsevier
, 2009 , Article)
The ac conductivity of glass samples of composition 50 mol% TeO2 and 50 mol% V2O5 has been analyzed. The samples were prepared by the usual melt-quench method. The electrical conductance and capacitance were measured over ...
Weak and strong convergence theorems without some widely used conditions
(
Academic Publications, Ltd.
, 2010 , Article)
We establish weak (strong) convergence of Ishikawa iterates of two asymptotically (quasi-)nonexpansive maps without any condition on the rate of convergence associated with the two maps. Moreover, our weak convergence ...
Empirical likelihood intervals for the population mean and quantiles based on balanced ranked set samples
(
Springer-Verlag
, 2008 , Article)
We consider nonparametric interval estimation for the population mean and quantiles based on a ranked set sample. The asymptotic distributions of the empirical log likelihood ratio statistic for the mean and quantiles are ...
Overlapping Schwarz waveform relaxation method for the solution of the convection-diffusion equation
(
John Wiley & Sons, Ltd.
, 2008 , Article)
In this article we study the convergence of the overlapping Schwarz wave form relaxation method for solving the convection-diffusion equation over multi-overlapped subdomains. It is shown that the method converges linearly ...
