Understanding probabilistic cognitive relaying communication with experimental implementation and performance analysis
(
MDPI AG
, 2019 , Article)
Efficiently use of the limited wireless spectrum can be achieved by cooperative cognitive relaying, where secondary users (SUs), who do not pay for the licensed spectrum and have better channel condition to the primary ...
A Modular Multilevel Converter with Ripple-Power Decoupling Channels for Three-Phase MV Adjustable-Speed Drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
This paper presents a drive system based on a modular multilevel converter (MMC) with high-frequency magnetic channels between adjacent-arm submodules (SMs), suitable for medium-voltage, high-power three-phase variable-speed ...
A Collaboration Incentive Exploiting the Primary-Secondary Systems' Cross Interference for PHY Security Enhancement
(
IEEE
, 2016 , Article)
We investigate the spectrum sharing possibility as an incentive to enhance the physical layer security. The concept behind is that a legitimate source-destination pair, communicating in the presence of a passive eavesdropper, ...
Molecular and electronic structure elucidation of Fe2+/Fe3+ complexed chelators used in iron sulphide scale removal in oil and gas wells
(
Wiley-Liss Inc.
, 2019 , Article)
Quantum chemical calculations based on DFT are employed to study the electronic structure and binding affinity of chelators used in the removal of iron sulphide scales. Three chelating agents, EDTA, HEDTA, and DTPA, are ...
Effect of copper-nickel interlayer thickness on laser welding-brazing of Mg/Ti alloy
(
Elsevier Ltd
, 2019 , Article)
Dissimilar lap joining of AZ31B Mg alloy to Cu-Ni coated Ti-6Al-4V was carried out by laser welding-brazing method. The effect of Cu and Ni contents on interfacial reaction and joint fracture load were analyzed. For the ...
Study on the impact of welding on the corrosion properties of AA 6061 T6
(
Trans Tech Publications Ltd
, 2014 , Article)
Aluminium alloy 6061 T6 circular specimens were joined using TIG welding method. AlMg5 was used as filler. The corrosion behavior of welded and un-welded AA 6061 T6 was investigated using potentiodynamic and open circuit ...
Application of Ni and Cu nanoparticles in transient liquid phase (TLP) bonding of Ti-6Al-4V and Mg-AZ31 alloys
(
Springer US
, 2014 , Article)
The transient liquid phase (TLP) bonding of Ti-6Al-4V alloy to a Mg-AZ31 alloy was performed using an electrodeposited Ni coating containing a dispersion of Ni and Cu nanoparticles. Bond formation was attributed to two ...
A quantum chemistry study of natural gas hydrates
(
Springer Verlag
, 2014 , Article)
The structure and properties of natural gas hydrates containing hydrocarbons, CO2, and N2 molecules were studied by using computational quantum chemistry methods via the density functional theory approach. All host cages ...
A PLM components monitoring framework for SMEs based on a PLM maturity model and FAHP methodology
(
Mundo Press
, 2014 , Article)
Right PLM components selection and investments increase business advantages. This paper develops a PLM components monitoring framework to assess and guide PLM implementation in small and middle enterprises (SMEs). The ...
Automatic detection of regions in spinach canopies responding to soil moisture deficit using combined visible and thermal imagery
(
Public Library of Science
, 2014 , Article)
Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of ...
