A novel converter for sinusoidal encoders
(
IEEE
, 2006 , Conference Paper)
The paper presents a novel and low cost method for determining the angle from sine and cosine signals generated by angular position sensors such as resolvers and sinusoidal encoders. The proposed scheme is based upon the ...
Fuzzy Expert System for Defect Classification for Non-Destructive Evaluation of Petroleum Pipes
(
IEEE
, 2007 , Conference Paper)
In this paper, an expert system has been outlined to classify the defects in metallic petroleum pipelines using acoustic techniques with non-destructive evaluation (NDE) protocols, the proposed system maps the quantitative ...
Lifetime maximization with predictive power management in selective relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2009 , Conference Paper)
A diversity scheme which exploits the existence of a source-destination path to improve the lifetime and outage probability of a wireless selective relay network with Amplifyand-Forward (AF) relays is proposed and studied. ...
A new angle determination method for resolvers
(
IEEE
, 2008 , Conference Paper)
A new low cost method for converting the amplitudes of the sine/cosine signals generated by the resolver into a measure of the angle of its shaft. The new method operates without lookup tables (LUT), and takes advantage ...
Lifetime maximization for greedy selective relay strategies
(2009 , Conference Paper)
In this paper we propose a new algorithm for selective relay strategies with Amplify-and-Forward (AF) relays which improves the relay network lifetime. The lifetime of the relay network is defined as the maximum number of ...
Halophytes and associated properties of natural soils in the Doha area, Qatar
(
Michigan State University Press
, 2007 , Conference Paper)
Plant life and the life they support are being eliminated and cannot cope with the construction activities in Doha City. One of the most important reasons behind this study is the fast rate at which many habitats are ...
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 ...
Hazards influencing coastal plains management along the Eastern stretch of the Gulf of Suez, Using remote sensing and GIS
(
IEEE
, 2008 , Conference Paper)
This research aims at to assess the impact of natural hazards on the human activities and development planning held along the eastern coastal stretch of the Gulf of Suez. Change detection technique was used in combined ...
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 ...
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 ...
