Distributed turbo coding using log-likelihood thresholding for cooperative communications
(
IEEE
, 2009 , Article)
In cooperative communications, error propagation at relays reduces the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is presented in ...
The Scientific Contributions of Arab Scientists to the International Research: a Study of the Indicators for Select Arab Countries
(
Blackwell Publishing Ltd
, 2009 , Article)
Using SCOPUS database, the research productivity of Arab researchers in five countries has been investigated. The analysis included subject, geographical and time range indicators. The relationship between the most published ...
Molecular phylogeny of Qatari date palm genotypes using Simple Sequence Repeats markers
(
Asian Network for Scientific Information
, 2009 , Article)
The objectives of the present study is to analyze the genetic diversity among 15 different cultivars of date palm at the experimental farm of Qatar University using Simple Sequence Repeat (SSR) markers and find out the ...
Maintaining the genetic health of putative Barbary lions in captivity: an analysis of Moroccan Royal Lions
(
Springer Berlin / Heidelberg
, 2009 , Article)
The last representatives of the Barbary lion (Panthera leo leo), once numerous in North Africa but exterminated from the wild by the 1940s, are believed to be the captive lions descended from the Moroccan Royal Collection, ...
Interestingness filtering engine: Mining Bayesian networks for interesting patterns
(
Elsevier Ltd
, 2009 , Article)
In this paper, we present a new measure of interestingness to discover interesting patterns based on the user’s background knowledge, represented by a Bayesian network. The new measure (sensitivity measure) captures the ...
Comparison of relaying strategies for cooperative diversity systems with adaptive modulation
(
IEEE
, 2009 , Conference Paper)
In this paper, we propose several relay selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes are based on dual-hop relaying with multiple relays. We analyze the performance ...
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 ...
Operational modeling of multistream heat exchangers with phase changes
(
Wiley Subscription Services, Inc., A Wiley Company
, 2009 , Article)
Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ...
Developing Engineering Learning Objects Online Portal with LabVIEW and an Open Source Web Content Management System
(
ASEE
, 2009 , Article)
Learning objects (LOs) are independent chunks of knowledge normally used for instructional or learning purposes. LOs are normally reusable in the sense that they can be adopted and adapted for various learning and instructional ...
One and two sample confidence intervals for estimating the mean of skewed populations: an empirical comparative study
(
TAYLOR & FRANCIS LTD
, 2009 , Article)
In this paper we consider and propose some confidence intervals for estimating the mean or difference of means of skewed populations. We extend the median t interval to the two sample problem. Further, we suggest using the ...
