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 ...
One and two sample confidence intervals for estimating the mean of skewed populations: an empirical comparative study
(
TAYLOR & FRANCIS LTD
, 2009 , Article)
In this paper we consider and propose some confidence intervals for estimating the mean or difference of means of skewed populations. We extend the median t interval to the two sample problem. Further, we suggest using the ...
High prevalence of the risk of overweight and overweight among Qatari children ages 9 through 11
(
Emerald
, 2009 , Article)
Purpose – The purpose of this paper is to estimate the prevalence of the risk of overweight and
overweight in Qatari children ages 9 through 11 and to compare the prevalence using CDC and IOTF
cut-offs.

A simulated annealing technique for multi-objective simulation optimization
(
Elsevier
, 2009 , Article)
In this paper, we present a simulated annealing algorithm for solving multi-objective simulation optimization problems. The algorithm is based on the idea of simulated annealing with constant temperature, and uses a rule ...
Wireless transmission using cooperation on demand
(
Elsevier B.V.
, 2009 , Article)
Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the cooperation is triggered only if the ...
An adaptive allocation sampling design for which the conventional stratified estimator is an appropriate estimator
(
Elsevier B.V.
, 2009 , Article)
Adaptive allocations in stratified sampling design are suitable for studying Biological and Environmental populations. Biologists tend to use the conventional stratified estimator for an adaptive allocation sampling design ...
An efficient dynamical systems method for solving singularly perturbed integral equations with noise
(
Elsevier
, 2009 , Article)
In this paper we apply the dynamical systems method (DSM) proposed by A. G. Ramm, and the variational regularization method (VRM), to obtain numerical solution to some singularly perturbed ill-posed problems contaminated ...
Density manifolds, geometric measures and high-energy physics in transfinite dimensions
(
Elsevier B.V.
, 2009 , Article)
We discuss certain manifolds with density. Furthermore, we outline natural connections leading to E-infinity theory and high-energy physics from a geometric measure and transfinite dimensional theoretical viewpoints.
The mathematical theory of finite and infinite dimensional topological spaces and its relevance to quantum gravity
(
Elsevier Ltd
, 2009 , Article)
The present work gives first a review of the mathematical theory of finite and infinite dimensional topological spaces. Subsequently we connect the discussion with E-infinity theory and the theory of partially ordered sets. ...
