A resolver converter based upon a novel open-Loop Technique
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from slowly-varying quadrature co-sinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, 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 ...
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 ...
A Discontinuous PWM Method for Balancing the Neutral Point Voltage in Three-Level Inverter-Fed Variable Frequency Drives
(
IEEE
, 2008 , Article)
The paper describes a new discontinuous carrier-based pulsewidth modulation (PWM) method for use in variable frequency drives (VFD) driven by three-level inverters. The method introduces three different switching patterns ...
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 ...
Do general indexes mask sectoral efficiencies?: A multiple variance ratio assessment of Middle Eastern equity markets
(
Emerald Group Publishing Limited
, 2008 , Article)
Purpose - The purpose of the paper is to attempt to shed light on whether the use of general indexes may mask sectoral efficiencies by investigating the random walk (RW) and weak-form efficiency (WFE) hypotheses in the ...
A novel algorithm for molecular synthesis using enhanced property operators
(
Elsevier Ltd
, 2008 , Article)
Traditionally process design and molecular design have been treated as two separate problems, with little or no feedback between the two approaches. Introduction of the property integration framework has allowed for ...
A systematic visual approach to molecular design via property clusters and group contribution methods
(
Elsevier Ltd
, 2008 , Article)
In this work, a new simple yet effective, systematic method to synthesize and design molecules is presented. Visualization of the problem is achieved by employing an annex to the recently developed property clustering ...
Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading
(
IEEE
, 2008 , Conference Paper)
Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ...
A Magnetic Transport Middle Eastern Positron Beam
(
Elsevier
, 2008 , Article)
A magnetically guided slow positron beam is being constructed at Qatar University and is currently being optimised for regular operation. This is the first positron beam in the Middle East, as well as being the first Arabic ...
