Relay selection in underlay cognitive networks with fixed transmission power nodes
(
John Wiley & Sons, Ltd.
, 2013 , Article)
Underlay cognitive networks operate simultaneously with primary networks satisfying stringent interference constraints, which reduces their transmission power and coverage area. To reach remote destinations, secondary ...
Global patterns and predictions of seafloor biomass using random forests
(
Public Library of Science
, 2010 , Article)
A comprehensive seafloor biomass and abundance database has been constructed from 24 oceanographic institutions worldwide within the Census of Marine Life (CoML) field projects. The machine-learning algorithm, Random ...
On fixed points of Berinde's contractive mappings in cone metric spaces
(
North University of Baia Mare
, 2010 , Article)
In this paper we establish some common fixed point theorems for two self-mappings satisfying a generalized contractive condition. This result generalizes well known comparable results in the literature. As an application, ...
A Model-driven Approach to the development of a PBL Script Editor

Effect of hyperlipidemia on ketoconazole-midazolam drug-drug interaction in rat
(
John Wiley & Sons, Ltd.
, 2011 , Article)
Hyperlipidemia (HL) was previously shown to lower liver uptake of the more potent (-) enantiomer of ketoconazole (KTZ) in rat. The current study examined the possible modifying influence of experimental HL on a KTZ ...

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 ...
Cost optimization of composite beams using genetic algorithms
(
Elsevier Ltd
, 2009 , Article)
This paper presents a genetic algorithm model for the cost optimization of composite beams based on the load and resistance factor design (LRFD) specifications of the AISC. The model formulation includes the cost of concrete, ...
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 ...
