A novel algorithm for molecular synthesis using enhanced property operators
(
Elsevier Ltd
, 2008 , Article)
Traditionally process design and molecular design have been treated as two separate problems, with little or no feedback between the two approaches. Introduction of the property integration framework has allowed for ...
A systematic visual approach to molecular design via property clusters and group contribution methods
(
Elsevier Ltd
, 2008 , Article)
In this work, a new simple yet effective, systematic method to synthesize and design molecules is presented. Visualization of the problem is achieved by employing an annex to the recently developed property clustering ...
Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading
(
IEEE
, 2008 , Conference Paper)
Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ...
Fixing the Kingdom: Political Evolution and Socio-Economic Challenges in Bahrain
(
Georgetown University School of Foreign Service in Qatar
, 2008 , Article)
Bahrain has entered into a more ‘progressive’ phase of its history under King Hamad bin Isa Al Khalifa. Various parliamentary and legislative restructuring, in addition to discernable changes within civil society, have ...
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 ...
On the numerical simulation of population dynamics with density-dependent migrations and the Allee effects
(
IOP Publishing
, 2008 , Article)
In this paper, the variational iteration method (VIM) and the Adomian decomposition method (ADM) are presented for the numerical simulation of the population dynamics model with density-dependent migrations and the Allee ...
Water resources assessment at El-Arish area, using remote sensing and GIS, North Sinai, Egypt
(
IEEE
, 2008 , Conference Paper)
This research aims at to analyse the pattern and rate of shoreline changes at the El-Arish area during the period 1984-2006, which represents the time at which the El-Arish harbour has affected along the coastline. Detecting ...
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 ...
