End-to-end outage probability of multihop transmission over lognormal shadowed channels
(
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 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 ...
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 ...
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 ...
Fuzzy time domain and Z-transform for modeling of harmonic electric loads
(
IEEE
, 2001 , Conference Paper)
This paper demonstrates the application of fuzzy systems and Z-transform for electric load modeling in the presence and/or absence of harmonics. The problem is formulated as one of linear optimization, where the objective ...
An open-loop technique for angle determination from position encoders
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ...
