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 ...
Solving fractional diffusion and wave equations by modified homotopy perturbation method
(
Elsevier B.V.
, 2007 , Article)
This Letter applies the modified He's homotopy perturbation method (HPM) suggested by Momani and Odibat to obtaining solutions of linear and nonlinear fractional diffusion and wave equations. The fractional derivative is ...
Likelihood and Bayesian estimation of using lower record values from the generalized exponential distribution
(
Elsevier Ltd
, 2007 , Article)
We consider the likelihood and Bayesian estimation of the stress-strength reliability based on lower record values from the generalized exponential distribution. The estimators are derived and their properties are studied. ...
Effect of Zn and Ni substitution on structural, morphological and magnetic properties of tin oxide nanoparticles
(
Elsevier
, 2016 , Article)
Structural, morphological, optical and magnetic properties of Zn and Zn–Ni co-doped tin oxide (SnO2) nanoparticles synthesized by sol-gel method. The influence of doping concentration on phase and particle size of the ...
On reality and asymptotics of zeros of q-Hankel transforms
(
Elsevier Inc.
, 2008 , Article)
We give sufficient conditions which guarantee that the finite q-Hankel transforms have only real zeros which satisfy some asymptotic relations. The study is carried out using two different techniques. The first is by a use ...
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 ...
Preparation, spectroscopic and structural studies on charge-transfer complexes of 2,9-dimethyl-1,10-phenanthroline with some electron acceptors
(
Elsevier
, 2007 , Article)
Charge-transfer (CT) complexes formed in the reactions of 2,9-dimethyl-1,10-phenanthroline (Me2phen) with some acceptors such as chloranil (Chl), picric acid (HPA) and chloranilic acid (H2CA) have been studied in the defined ...
Application of generalized differential transform method to multi-order fractional differential equations
(
Elsevier
, 2007 , Article)
In a recent paper [Odibat Z, Momani S, Erturk VS. Generalized differential transform method: application to differential equations of fractional order, Appl Math Comput. submitted for publication] the authors presented a ...
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 ...
