Modeling of mass transport of aqueous solutions of multi-solute organics through reverse osmosis membranes in case of solute–membrane affinity: Part 1. Model development and simulation
(
Elsevier B.V.
, 2005 , Article)
A two-dimensional mathematical model is developed for transport of multi-solute liquid (aqueous) solutions through reverse osmosis membranes in which strong affinity may exist between the membrane polymer and the solutes. ...
Artificial neural network-based kinematics Jacobian solution for serial manipulator passing through singular configurations
(
Elsevier Ltd
, 2009 , Article)
Singularities and uncertainties in arm configurations are the main problems in kinematics robot control resulting from applying robot model, a solution based on using Artificial Neural Network (ANN) is proposed here. The ...
Student satisfaction with an educational administration preparation program: A comparative perspective

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. ...
Markedly improved CO2 capture efficiency and stability of gallium substituted hydrotalcites at elevated temperatures
(
American Chemical Society
, 2009 , Article)
Potassium carbonate promoted, Ga3+ substituted hydrotalcites reported here exhibit very high, selective and reversible CO2 capture from an exhaust gas mixture. The 10% Ga3+ substitution improved the CO2 capture from 0.3 ...
Photocatalytic degradation of methyl orange as a model compound
(
Elsevier
, 2002 , Article)
Titanium dioxide (TiO2) was used as a photocatalyst for the detoxification of water containing methyl orange (MO), which was used as a model compound. Solar radiation was used as an irradiation source. It was found that ...
A cascade of artificial neural networks to predict transformers oil parameters
(2009 , Article)
In this paper artificial neural networks have been constructed to predict different transformers oil parameters. The prediction is performed through modeling the relationship between the insulation resistance measured ...
Synthesis, spectroscopic and thermal structural investigations of the charge-transfer complexes formed in the reaction of 1-methylpiperidine with σ- and π-acceptors
(
Elsevier B.V.
, 2009 , Article)
The reactions of the electron donor 1-methylpiperidine (1MP) with the π-acceptors 7,7,8,8-tetracyanoquinodimethane (TCNQ), tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ), 2,3,5,6-tetrachloro-1,4 ...
An adaptive Monte Carlo integration algorithm with general division approach
(
Elsevier
, 2007 , Article)
We propose an adaptive Monte Carlo algorithm for estimating multidimensional integrals over a hyper-rectangular region. The algorithm uses iteratively the idea of separating the domain of integration into 2ssubregions. The ...
Voluntary disclosure in the annual reports of an emerging country: The case of Qatar
(
Elsevier Ltd
, 2009 , Article)
This study sets out to examine empirically the determinants of voluntary disclosure in the annual reports of 25 listed firms of Doha Securities Market (DSM) in Qatar forming approximately 86% of the total firms incorporated ...
