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 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 ...
End-to-end performance of transmission systems with relays over Rayleigh-fading channels
(
IEEE
, 2003 , Article)
End-to-end performance of two-hops wireless communication systems with nonregenerative relays over flat Rayleigh-fading channels is presented. This is accomplished by deriving and applying some new closed-form expressions ...

جامعة الأزهر - كلية أصول الدين و الدعوة بالزقازيق
, 2009 , Article)
تسهم الخدمات التطوعية بدور كبير في بناء كثير من الحضارات و المجتمعات على مر العصور. حيث انها لا تمثل مهنة وبصفتها عملاً خالياً من الربح يقوم به مجموعة من الأفراد من اجل الغير. وتأخذ أشكالا وانماطاً متعددة منها الذاتية ومنها ...
Recognition of off-line handwritten Arabic words using neural network
(
IEEE
, 2006 , Conference Paper)
Neural network (NN) have been used with some success in recognizing printed Arabic words. In this paper, a complete scheme for unconstrained Arabic handwritten word recognition based on a Neural network is proposed and ...
Highly accurate solutions of the bifurcation structure of mixed-convection heat transfer using spectral method
(
John Wiley & Sons, Ltd.
, 2002 , Article)
This paper is concerned with producing highly accurate solution and bifurcation structure using the pseudo-spectral method for the two-dimensional pressure-driven flow through a horizontal duct of a square cross-section ...
Channel assignment of microcellular mobile radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2006 , Conference Paper)
This paper addresses the analytical and simulation modeling of non overlapping microcells with both non-prioritized and prioritized handover schemes. The network performance is analyzed in terms of the analytical results ...
Spectroscopic investigation of the donor-acceptor interaction between o-phenylenediamine and tetracyanoethylene in dichloromethane
(
Elsevier B. V.
, 2007 , Article)
The interaction between the electron donor o-phenylenediamine (o-phendn) and the π-acceptor tetracyanoethylene (TCNE) has been investigated spectrophotometrically in dichloromethane at 25 °C. The results indicate that the ...
Attracting High Achieving Secondary Students through Early Admission Call-Up in an American Style College in Lebanon: A Comparison with American Colleges
(
National Association for College Admission Counseling
, 2009 , Article)
An early admission call-up was used to attract high-achieving students to a private university in Lebanon. The callup,
which is essentially an offer of admission before the student takes any formal steps, was administered ...
