Incentive scheduler algorithm for cooperation and coverage extension in wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
In this paper, we focus on wireless coverage extension and nodes' cooperation. We propose a new protocol based on an incentive approach and a scheduling algorithm to reward cooperative nodes. The cost of cooperation can ...
MIP models for minimizing total tardiness in a two-machine flow shop
(
Palgrave Macmillan Ltd.
, 2013 , Article)
We propose compact mixed-integer programming models for the NP-hard problem of minimizing tardiness in a two-machine flow shop. Also, we propose valid inequalities that aim at tightening the models' representations. We ...
Photo-oxidative enhancement of polymeric molecular sieve membranes
(
Nature Research
, 2013 , Article)
High-performance membranes are attractive for molecular-level separations in industrial-scale chemical, energy and environmental processes. The next-generation membranes for these processes are based on molecular sieving ...
High pressure CO2 absorption studies on imidazolium-based ionic liquids: Experimental and simulation approaches
(2013 , Article)
A combined experimental-computational study on the CO2 absorption on 1-butyl-3-methylimidazolium hexafluophosphate, 1-ethyl-3-methylimidazolium bis[trifluoromethylsulfonyl]imide, and 1-butyl-3-methylimidazolium ...
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
(
Wiley Online Library
, 2013 , Article)
In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ...
Chemical composition and evaluation of antioxidant and antimicrobial activities of Tunisian Thymelaea hirsuta with special reference to its mode of action
(
Elsevier B.V.
, 2013 , Article)
In the present study, we evaluated in vitro antimicrobial and antioxidant properties of Thymelaea hirsuta extracts as well as its phytochemical composition. Total phenolic and flavonoid contents were highest in acetone and ...
A Portrait of Low-Income Migrants in Contemporary Qatar
(
Taylor & Francis (Routledge)
, 2013 , Article)
Though transnational labor migration in the Gulf States has increasingly been of
scholarly interest, that scholarship has to date relied largely on qualitative ethnographic
methodologies or small non-representative ...
Moisture and temperature dependence of the dielectric properties of pharmaceutical powders
(2013 , Article)
The dielectric properties of pharmaceutical powder–(paracetamol, aspirin, lactose, maize starch, adipic acid) solvent (water) mixtures were measured at 2,450 MHz at a range of moisture contents (0–1.0 kg kg−1, dry basis) ...
Microstructure, thermal and mechanical response of AZ51/Al2O3 nanocomposite with 2 wt.% Ca addition
(
Elsevier, Ltd
, 2013 , Article)
In the present study, new AZ51/Al2O3–2Ca magnesium nanocomposite was successfully synthesized by simultaneously adding 2wt.% aluminum, 2wt.% Ca and 1.5vol.% nanosized Al2O3 (50nm) into AZ31 matrix using a disintegrated ...
An improved palmprint recognition system using iris features
(
Springer
, 2013 , Article)
This paper presents a bimodal biometric recognition system based on the extracted features of the human palmprint and iris using a new graph-based approach termed Fisher locality preserving projections (FLPP). This new ...
