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 ...
Stochastic learning automata-based channel selection in cognitive radio/dynamic spectrum access for WiMAX networks
(
John Wiley & Sons, Ltd.
, 2015 , Article)
This paper proposes a cognitive radio-based dynamic bandwidth allocation scheme for secondary users in a cluster-based WiMAX network. It uses a learning automata-based algorithm to find the optimal transmission channel, ...
Second law analysis of compressible flow through a diffuser subjected to constant wall temperature
(
Inderscience
, 2010 , Article)
This study presents the investigation of entropy generation in compressible turbulent flow of air through a diffuser. Constant temperature boundary condition is applied at the wall. Two-dimensional solution of velocity and ...
Weak and strong convergence theorems without some widely used conditions
(
Academic Publications, Ltd.
, 2010 , Article)
We establish weak (strong) convergence of Ishikawa iterates of two asymptotically (quasi-)nonexpansive maps without any condition on the rate of convergence associated with the two maps. Moreover, our weak convergence ...
Nano-scale moisture damage evaluation of carbon nanotube-modified asphalt
(
Elsevier
, 2018 , Article)
© 2018 Elsevier Ltd In addition to polymer modification, the use of nanomaterials to improve different asphalt properties has recently been found to be beneficial. However, the potential of nanomaterials in pavement ...
Sociolinguistic anatomy of mobility: Evidence from Qatar
(
Elsevier
, 2015 , Article)
Abstract This is a sociocultural linguistic study on the ways whereby mobility is reflected upon in life narratives. An ethnographically informed sociolinguistic scale analysis shows that when residents narrate their life ...
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), ...
Photocatalytic removal of phenol from refinery wastewater: Catalytic activity of Cu-doped titanium dioxide
(
Elsevier Ltd
, 2015 , Article)
A series of Cu-doped TiO2 catalysts were prepared by a sol-gel method and the effect of various synthesis parameters, including solvent type; solvent/catalyst amount; amount of water; catalyst type/amount; and acid type, ...
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 ...
