Estimating design effort for the compressor design department: a case study at Pratt & Whitney Canada
(
Elsevier Ltd
, 2009 , Article)
The effort required in a design project not only impacts the final cost, but also the project lead-time. This paper presents a case study carried out with the collaboration of Pratt & Whitney Canada, a global leader in the ...
Controlling Error Propagation in Network-Coded Cooperative Wireless Systems
(
IEEE
, 2009 , Article)
In cooperative communications, error propagation at relays degrades the diversity order of the system. To combat that effect, it has been suggested to implement a reliability threshold at the relay to control error ...
Synthesis, spectroscopic, thermal and structural investigations of charge-transfer complexes of 4,4′-trimethylenedipiperidine with chloranil, TBCHD, DDQ, TCNQ and iodine
(
Elsevier
, 2009 , Article)
The charge-transfer interactions between the electron donor 4,4′-trimethylenedipiperidine (TMDP) and the acceptors 2,3,5,6-tetrachloro-1,4-benzoquinone (chloranil), 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TBCHD), ...
Cross-Layer Optimal Rate Allocation for Heterogeneous Wireless Multicast
(
Hindawi Publishing Corporation
, 2009 , Article)
Heterogeneous multicast is an efficient communication scheme especially for multimedia applications running over multihop networks. The term heterogeneous refers to the phenomenon when multicast receivers in the same session ...
Wireless Multicast Cross-Layer Framework for Rate
(
IEEE
, 2009 , Article)
Multicast-based data communication is an efficient communication scheme especially in multihop ad hoc networks where the MAC layer is based on one-hop broadcast from one source to multiple receivers. In this paper, we ...
Characteristics of agent-based hierarchical diff-EDF schedulability over heterogeneous real-time Packet networks
(
EuroJournals Publishing, Inc.
, 2009 , Article)
Packet networks are currently enabling the integration of heterogeneous traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to best-effort traffic requiring no ...
Efficient Channel Allocation Scheme with Triangle Communication
(
IEEE
, 2009 , Article)
Radio is a valuable resource for wireless/mobile communication systems. In this paper, we present an efficient algorithm using a novel triangle communication model to synchronize processes effectively by searching for free ...
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 ...
