Mechanical and thermal stresses in a functionally graded rotating disk with variable thickness due to radially symmetry loads
(
Elsevier Ltd
, 2008 , Article)
Rotating disks have many applications in the aerospace industry such as gas turbines and gears. These disks normally work under thermo mechanical loads. Minimizing the weight of such components can help reduce the overall ...
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
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 ...
Present day inbreeding does not forbid the forensic utility of commonly explored STR loci: A case study of native Qataris
(
Elsevier Ireland Ltd.

Allele frequency distribution of 15 short tandem repeat (STR) loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA) was studied in a sample of 120 ...
Application of homotopy-perturbation method to fractional IVPs
(
Elsevier
, 2008 , Article)
Fractional initial-value problems (fIVPs) arise from many fields of physics and play a very important role in various branches of science and engineering. Finding accurate and efficient methods for solving fIVPs has become ...
Cobalt phthalocyanine as a novel molecular recognition reagent for batch and flow injection potentiometric and spectrophotometric determination of anionic surfactants
(
Elsevier B. V.
, 2008 , Article)
Cobalt(II) phthalocyanine [Co(II)Pc] is used as both an ionophore and chromogen for batch and flow injection potentiometric and spectrophotometric determination of anionic surfactants (SDS), respectively. The potentiometric ...

(
Elsevier
, 2008 , Article)
The solid charge-transfer complexes formed in the reaction of the electron donor 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTACN) with the acceptors iodine, tetracyanoethylene (TCNE) and 7,7,8,8-tetracyanoquinodimethane ...
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 ...
