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 ...
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 ...
Chip-Level Modulated BPPM Fiber-Optic Code Division Multiple Access
(
IEEE
, 2009 , Conference Paper)
Chip-Level Modulated Binary Pulse Position Modulation (CLM-BPPM) is proposed as a modulation scheme for Fiber-Optic Code Division Multiple Access (FO-CDMA) systems using Optical Orthogonal Code (OOC) for time domain signal ...
A predictive strategy for lifetime maximization in selective relay networks
(
IEEE
, 2009 , Conference Paper)
Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ...
Water resources assessment at El-Arish area, using remote sensing and GIS, North Sinai, Egypt
(
IEEE
, 2008 , Conference Paper)
This research aims at to analyse the pattern and rate of shoreline changes at the El-Arish area during the period 1984-2006, which represents the time at which the El-Arish harbour has affected along the coastline. Detecting ...
Semantic Map Based Web Search Result Visualization
(
IEEE
, 2007 , Conference Paper)
The problem of information overload has become more pressing with the emergence of the increasingly more popular Internet services. The main information retrieval mechanisms provided by the prevailing Internet Web software ...
Stemming Versus Light Stemming as Feature Selection Techniques for Arabic Text Categorization
(
IEEE
, 2007 , Conference Paper)
This paper compares and contrasts two feature selection techniques when applied to Arabic corpus; in particular; stemming, and light stemming were employed. With stemming, words are reduced to their stems. With light ...
Predicting transformers oil parameters
(
IEEE
, 2009 , Conference Paper)
In this paper different configurations of artificial neural networks are applied to predict various transformers oil parameters. The prediction is performed through modeling the relationship between the transformer insulation ...
Analysis of a Cell-based Call Admission Control Scheme for QoS Support in Multimedia Wireless Networks
(
IEEE
, 2007 , Conference Paper)
Next generation wireless communication systems target to provide guaranteed quality of service (QoS) for multimedia applications. In this paper, a multiple-threshold bandwidth reservation scheme combined with a call admission ...
