Numerical comparison of methods for solving a special fourth-order boundary value problem
(
Elsevier Inc.
, 2007 , Article)
In this paper, we implement relatively new analytical techniques, the differential transform method, Adomian decomposition, and homotopy perturbation method, for solving a fourth-order boundary value problem. In these ...
An efficient technique for finding the eigenvalues of fourth-order Sturm–Liouville problems
(
Elsevier
, 2009 , Article)
In this paper, we will develop a numerical technique for finding the eigenvalues of fourth-order non-singular Sturm–Liouville problems. We used the variational iteration methods as a basis for this technique. Numerical ...
Complex-impedance response of an Ag/TeO2-V2O5/Ag structure
(
Elsevier
, 2009 , Article)
The ac conductivity of glass samples of composition 50 mol% TeO2 and 50 mol% V2O5 has been analyzed. The samples were prepared by the usual melt-quench method. The electrical conductance and capacitance were measured over ...
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 ...
Synthesis, spectroscopic, thermal and structural investigations of charge-transfer complexes of 4,4′-trimethylenedipiperidine with chloranil, TBCHD, DDQ, TCNQ and iodine
(
Elsevier
, 2009 , Article)
The charge-transfer interactions between the electron donor 4,4′-trimethylenedipiperidine (TMDP) and the acceptors 2,3,5,6-tetrachloro-1,4-benzoquinone (chloranil), 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TBCHD), ...
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 ...
Competition, facilitation, and niche differentiation in two foliar pathogens
(
Springer Berlin / Heidelberg
, 2004 , Article)
We studied competition between the obligate biotroph Puccinia triticina (designated here as Puccinia) and the facultative saprophyte Pyrenophora tritici-repentis (designated here as Pyrenophora) in older and younger leaves ...
Ecophysiology of Limonium axillare and Avicennia marina from the coastline of Arabian Gulf-Qatar
(
Springer Science + Business Media B.V.
, 2008 , Article)
Attention is being focused on the coastline from Doha to Ras Laffan in Qatar since higher activities in the development of land and establishment of roads, highways and new buildings and houses is not coupled by serious ...
Reduction kinetics of ceria surface by hydrogen
(
Wiley Periodicals, Inc.
, 2004 , Article)
Powdered cerium dioxide (ceria, CeO2) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm?3, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity ...
