Baseline formation for damage diagnosis in a turbine blade
(
Aalborg University
, 2005 , Conference Paper)
In the absence of a baseline for the pre-damaged structures, an attempt is made to create one, analytically, using dimensional analysis and physically using stereolithography. First, a preliminary diagnosis check is performed ...
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 ...

Synthesis, spectroscopic and thermal investigations of solid charge-transfer complexes of 1,4,7-trimethyl-1,4,7-triazacyclononane and the acceptors iodine, TCNE, TCNQ and chloranil
(
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 ...
الأخبار الغیبیة الدنیویة کما جاءت فی القرآن الکریم
(
جامعة الأزهر
, 2001 , Article)
لا شك أن نسيان الإنسان لبعض الغيب الماضي من صالحه في دنياه وأخراه، فهناك العداوات والمظالم التي وقعت بين الأصول، وبين الدول والقبائل والشعوب، لو لم تطو صحائها، وتندثر معالمها، ولو لم تنس في بطون التاريخ وغابر الأزمان لكانت ...
First record of microsporedean and myxosporeans (Protozoa) infecting some Arabian Gulf fish off the coasts of Emirates and Qatar with a description Myxobolus arabicus n.sp
(
Arabian Gulf University
, 2002 , Article)
During a comprehensive survey carried out on helminth parasites of Arabian Gulf fishes mainly from the coasts of the Emirates and Qatar, two microsporeans and three myxosporeans Protozoa were reported and described for the ...
Wireless transmission with cooperation on demand for slow and fast fading environments
(
IEEE
, 2008 , Conference Paper)
Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the relay chooses to cooperate only if the ...
Operational modeling of multistream heat exchangers with phase changes
(
Wiley Subscription Services, Inc., A Wiley Company
, 2009 , Article)
Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ...
Homotopy perturbation method for nonlinear partial differential equations of fractional order
(
Elsevier B.V.
, 2007 , Article)
The aim of this Letter is to present an efficient and reliable treatment of the homotopy perturbation method (HPM) for nonlinear partial differential equations with fractional time derivative. The fractional derivative is ...
A Resolver Angle Estimator Based on Its Excitation Signal
(
IEEE
, 2009 , Article)
A resolver generates a pair of signals proportional to the sine and cosine of the angular position of its shaft. A new low-cost method for converting the amplitudes of these sine/cosine transducer signals into a measure ...
