Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference Paper)
Multihop transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several, possibly shorter links/hops. This paper presents an expression for the moment ...
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 ...
A new iterative learning control method for PWM inverter current regulation
(
IEEE
, 2003 , Conference Paper)
AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. PWM inverters output waveforms ...
Digital control for UPS inverters
(
IEEE
, 2003 , Conference Paper)
PWM inverters digital controls with dead-beat re sponse, for UPS applications, are reviewed. To improve the output waveforms of the PWM inverter, several modern control techniques are applied together with the deadbeat ...
An approach for constructing complex discriminating surfaces based on Bayesian interference of the maximum entropy
(
Elsevier Inc.
, 2003 , Article)
In this paper we present a comprehensive Maximum Entropy (MaxEnt) procedure for the classification tasks. This MaxEnt is applied successfully to the problem of estimating the probability distribution function (pdf) of a ...
A multi-level conceptual data reduction approach based on the Lukasiewicz implication
(
Elsevier Science Inc
, 2003 , Article)
Starting from fuzzy binary data represented as tables in the fuzzy relational database, in this paper, we use fuzzy formal concept analysis to reduce the tables size to only keep the minimal rows in each table, without ...
Non-linear simulation of controller for longitudinal control augmentation system of F-16 using numerical approach
(
Elsevier Inc
, 2003 , Article)
The non-linear simulation of controller for automatic flight control system is an essential part of the complete control design process. After using the linear approach in the design and simulation of the controller (control ...

In recent years the involvement of Information Technology in business,
governments, and education has increased dramatically. More and more research
works have been conducted in different areas of Information Technology
such ...
Chronostratigraphy and geochemical characterization of volcanic rocks from the Hormuz Complex: Constraints from the Halul Island, The State of Qatar
(
sultan qaboos university
, 2003 , Article)
Geochemical and Sr-Nd isotopic data are reported for volcanic rocks in the Hormuz Complex, Halul Island, Eastern Qatar. Two groups of volcanic rocks are distinct in their geochemical characteristics. Group 1 samples have ...
Positron annihilation studies of the effect of gamma irradiation dose in polymers
(
Elsevier Ltd
, 2003 , Conference Paper)
Positron annihilation lifetime (PAL) technique has been applied to study the effect of gamma irradiation dose on the structure of low-density polyethylene and polystyrene. The positron annihilation lifetime measurements ...
