(
King Fahd University of Petroleum & Minerals
, 2003 , Article)
End-to-end outage probability evaluation of multihop wireless communication systems over lognormal shadowed channels is presented. Closed-form expression for the end-to-end signal to noise ratio of systems equipped with ...
Long-term electric peak load forecasting for power system planning: A comparative study
(
King Fahd University of Petroleum and Minerals
, 2004 , Article)
A comparative study between two static estimation algorithms, namely least error squares (LES) and least absolute value (LAV) algorithm was presented. The proposed algorithm used the past history data for the load and 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 ...
Power system frequency estimation based on simulated annealing. Part I: A constant frequency study
(
King Fahd University of Petroleum and Minerals
, 2003 , Article)
In this paper a new algorithm based on Simulated Annealing (SA) method is used to estimate the signal parameters of a system steady power system, having a constant frequency during data window size. The proposed algorithm ...
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 ...
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 ...
Developing Engineering Learning Objects Online Portal with LabVIEW and an Open Source Web Content Management System
(
ASEE
, 2009 , Article)
Learning objects (LOs) are independent chunks of knowledge normally used for instructional or learning purposes. LOs are normally reusable in the sense that they can be adopted and adapted for various learning and instructional ...
Fuzzy system applications for identification of weak buses in power systems
(
King Fahd University of Petroleum and Minerals
, 2002 , Article)
In this paper a simple new algorit hm for identifying the weak buses in a power system for voltage stability study is presented. The proposed algorithm is based on fuzzy set theory. Two membership functions, one for voltage ...
Generalized dynamic spectrum access: An order statistics design perspective
(
Elsevier GmbH
, 2008 , Article)
A new adaptive multiple access scheme based on the theory of order statistics is introduced. The proposed algorithm employs a semi-random allocation mechanism that limits subchannel selection to the highest-gain subchannels. ...
Digitally-tuned resolver converter
(
Elsevier B.V.
, 2009 , Article)
Sinusoidal encoders provide electrical signals related to the sine and cosine of the mechanical shaft angle θ. An analog converter is described for the linearization of these signals and hence for linear computation of θ. ...
