Two digital filtering algorithms for fast estimation of symmetrical components in a power system: A static estimation approach
(
Elsevier
, 2003 , Article)
This paper presents the application of two digital filters working together for fast estimation of power systems symmetrical components. The three-phase unbalanced system is transformed to two phases using α–β-transformation. ...

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 ...

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 ...
