Numerical methods for nonlinear partial differential equations of fractional order
(
Elsevier B.V.
, 2008 , Article)
In this article, we implement relatively new analytical techniques, the variational iteration method and the Adomian decomposition method, for solving nonlinear partial differential equations of fractional order. The ...
Synthesis, spectroscopic and thermal studies of the reactions of the donors piperazine and N,N′-dimethylpiperazine with σ- and π-acceptors
(
Elsevier
, 2008 , Article)
Abstract The interactions of the electron donors piperazine (PIP) and N,N′-dimethylpiperazine (DMPIP) with the σ-acceptor iodine and the π-acceptors tetracyanoethylene (TCNE) and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone ...

إن هذا البحث يؤكد أن هناك حاجة ملحة إلى رسم سياسات سكانية ، إذا ما أردنا أن نخطط للمستقبل بشكل إيجابي في كافة الجوانب ذات الصلة بالإنسان والمجتمع الخليجي وذلك قبل أن تتأزم الأمور وتتشابك إشكاليات المسألة السكانية آخذين ...
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 ...
Simpler is also better in approximating fixed points
(
Elsevier
, 2008 , Article)
In this paper we demonstrate that a number of fixed point iteration problems can be solved using a modified Krasnoselskij iteration process, which is much simpler to use than the other iteration schemes that have been defined
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 ...
Tutorials-Based System to Assist Qatari Children with Special Needs
(
IEEE
, 2008 , Article)
The objective of this project is to develop an Arabic predictive communication system for physically disabled people with speech and language impairments who are resident at the Shafalah Qatari center for children with ...
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 ...
Role of catalyst type in the selective separation of olefinic and paraffinic hydrocarbons using xerogel-based adsorbents
(
Elsevier
, 2008 , Article)
Resorcinol-Formaldehyde (RF)-based activated carbon xerogels are typically synthesized using a homogeneous, sodium-based, catalyst solution. In this work, the synthesis of RF-based carbon xerogels using other, non-typical, ...
Geology and petrology of the Hormuz dolomite, Infra-Cambrian: Implications for the formation of the salt-cored Halul and Shraouh islands, Offshore, State of Qatar
(
Elsevier Ltd
, 2008 , Article)
Geological investigations of the Halul and the Shraouh islands, offshore Qatar, indicate that most of their calcareous rocks, which display abundant stromatolitic bedding, belong to the Infra-Cambrian Hormuz Series. ...
