A novel multilevel carrier-based PWM-control method for GTO inverter in low index modulation region
(
IEEE
, 2006 , Article)
Gate turn offs (GTOs) have an inherent minimum ON-OFF time, which is needed for their safe operation. For GTO-based three-level or neutral-point-clamped (NPC) inverters, this minimum ON-OFF pulsewidth limitation results ...
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 ...
An adaptive allocation sampling design for which the conventional stratified estimator is an appropriate estimator
(
Elsevier B.V.
, 2009 , Article)
Adaptive allocations in stratified sampling design are suitable for studying Biological and Environmental populations. Biologists tend to use the conventional stratified estimator for an adaptive allocation sampling design ...
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 ...
User cooperation schemes in the soft handover regions
(
IEEE
, 2009 , Conference Paper)
This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ...
Phylogeography of lions (Panthera leo ssp.) reveals three distinct taxa and a late Pleistocene reduction in genetic diversity
(
Blackwell Publishing Ltd
, 2009 , Article)
Lions were the most widespread carnivores in the late Pleistocene, ranging from southern Africa to the southern USA, but little is known about the evolutionary relationships among these Pleistocene populations or the ...
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 ...
Spectroscopic investigation of the charge-transfer interactions between 1,4,7-trimethyl-1,4,7-triazacyclononane and the acceptors iodine, TCNE, TCNQ and chloranil
(
Elsevier
, 2007 , Article)
The interaction of the interesting polynitrogen cyclic base 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTACN) with the σ-acceptor iodine and π-acceptors tetracyanoethylene (TCNE), 7,7,8,8-tetracyanoquinodimethane (TCNQ) and ...
New Heuristic Strategies for Reactive Power Compensation of Radial Distribution Feeders
(
IEEE
, 2002 , Article)
In this paper, the authors introduce two new heuristic techniques for reactive power compensation in radial distribution feeders. The methods can be considered as generalization ideas that emerged from recent heuristic ...
