Solving systems of fractional differential equations using differential transform method
(
Elsevier B.V.
, 2007 , Article)
This paper presents approximate analytical solutions for systems of fractional differential equations using the differential transform method. The fractional derivatives are described in the Caputo sense. The application ...
A Novel Resolver-to-360° Linearized Converter
(
IEEE
, 2004 , Article)
A novel and simple resolver-to-dc converter is presented. It is shown that by appropriate processing of the sine and cosine resolver signals, the proposed converter may produce an output voltage proportional to the shaft ...
The multistage homotopy-perturbation method: A powerful scheme for handling the Lorenz system
(
Elsevier
, 2007 , Article)
In this paper, a new reliable algorithm based on an adaptation of the standard homotopy-perturbation method (HPM) is presented. The HPM is treated as an algorithm in a sequence of intervals (i.e. time step) for finding ...
Maintaining the genetic health of putative Barbary lions in captivity: an analysis of Moroccan Royal Lions
(
Springer Berlin / Heidelberg
, 2009 , Article)
The last representatives of the Barbary lion (Panthera leo leo), once numerous in North Africa but exterminated from the wild by the 1940s, are believed to be the captive lions descended from the Moroccan Royal Collection, ...
Effects of treated municipal wastewater and sea water irrigation on soil and plant characteristics
(
Springer Nature
, 2009 , Article)
The increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. Using treated wastewater in agricultural irrigation can provide more ...
Seroprevalence and epidemiological correlates of Toxoplasma gondii infections among patients referred for hospital-based serological testing in Doha, Qatar
(
BioMed Central
, 2008 , Article)
Background. The city of Doha in Qatar has a high density of feral cats and there is a high risk of toxoplasmosis for the resident human population. No data currently exist for the prevalence of infection with Toxoplasma ...
Determination and selecting the optimum thickness of insulation for buildings in hot countries by accounting for solar radiation
(
Elsevier
, 2004 , Article)
Determination and selecting the optimum thickness of insulation is the prime interest of many engineering applications. One of those applications is insulating buildings with an appropriate insulation. Calculations have ...
Estimation of Pr(X ≤ Y) using record values in the one and two parameter exponential distributions
(
Taylor & Francis
, 2008 , Article)
Abstract
We consider the problem of estimating the stress-strength reliability when the available data is in the form of record values. The one parameter and two parameters exponential distribution are considered. In the ...
Application of Homotopy Perturbation Method to Singularly Perturbed Volterra Integral Equations
(
Asian Network for Scientific Information
, 2008 , Article)
In this study, the Homotopy-Perturbation Method (HPM) proposed by J.-H. He is adopted for solving singularly perturbed Volterra integral equations (SVIEs). Three numerical examples are given to demonstrate the effectiveness ...
A New Low Cost Linear Resolver Converter
(
IEEE
, 2008 , Article)
A new low cost converter topology is proposed for sinusoidal position encoders. The converter enables determination of the angle from the sine and cosine signals of the encoder. When used with resolvers, the implementation ...
