Complex-impedance response of an Ag/TeO2-V2O5/Ag structure
(
Elsevier
, 2009 , Article)
The ac conductivity of glass samples of composition 50 mol% TeO2 and 50 mol% V2O5 has been analyzed. The samples were prepared by the usual melt-quench method. The electrical conductance and capacitance were measured over ...
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), ...
Economic Policies and the Possibilities of Unified GCC Currency
(
Qatar University
, 2006 , Article)
The aim of this study is to identify the extent to which the GCC countries can adopt similar economic policies by the time the GCC unified currency is formed in 2010. Among other convergence standards, we examined the ...
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 ...
A methodology for time-frequency image processing applied to the classification of nonstationary multichannel signals using instantaneous frequency descriptors with application to newborn EEG signals
(
Springer
, 2003 , Article)
This article presents a general methodology for processing non-stationary signals for the purpose of classification and localization. The methodology combines methods adapted from three complementary areas: time-frequency ...
Empirical likelihood intervals for the population mean and quantiles based on balanced ranked set samples
(
Springer-Verlag
, 2008 , Article)
We consider nonparametric interval estimation for the population mean and quantiles based on a ranked set sample. The asymptotic distributions of the empirical log likelihood ratio statistic for the mean and quantiles are ...
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 ...
