Thermal conductivity and latent heat thermal energy storage properties of LDPE/wax as a shape-stabilized composite phase change material
(2014 , Article)
Phase change material (PCM) composites based on low-density polyethylene (LDPE) with paraffin waxes were investigated in this study. The composites were prepared using a meltmixing method with a Brabender-Plastograph. The ...
Perspectives on food waste management: Prevention and social innovations
(
Elsevier
, 2022 , Article Review)
Food waste is one of the challenging issues humans are facing. A third of the food produced in the world is wasted at various points along the food supply chain. Food waste can be reduced by developing technology that can ...
Investigation of the Effect of The Temperature and Magnetization Pattern on Flux Density, Instantaneous Torque, Unbalanced Magnetic Forces of a Surface Inset PMM
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Conference Paper)
Electrical machines utilized in domestic applications such as ceiling fans should have low losses and cost. Permanent magnets are used instead of rotor excitation to reduce losses. Therefore, not only the losses of the ...
Application of cobalt incorporated Iron oxide catalytic nanoparticles for thermochemical conversion of CO2
(
Elsevier B.V.
, 2019 , Article)
This investigation describes the application of the sol-gel synthesized CoxFe3?xO4 (CF) materials towards the solar thermochemical fuel production. The CF materials were derived by sol-gel method (where x was varied in the ...
Transport layer performance analysis and optimization for smart metering infrastructure
(
Elsevier
, 2014 , Article)
In a smart power grid, collecting data from a large number of smart meters and sensors over the conventional one-hop transmission control protocol (TCP) communication is prone to a high packet loss rate and degraded ...
Deadbeat control of Z source inverter with voltage ride-through capability
(
IEEE
, 2013 , Conference Paper)
This paper presents a Z source inverter connected to grid. The effect of voltage sags on ZSI will be studied when two different ac side control schemes are used. The paper compares the performance of both PI control and ...
On the Achievable Secrecy Diversity of Cooperative Networks with Untrusted Relays
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
Cooperative relaying is often deployed to enhance the communication reliability (i.e., diversity order) and consequently the end-to-end achievable rate. However, this raises several security concerns when the relays are ...
Refining the ambiguity domain characteristics of non-stationary signals for improved time–frequency analysis: Test case of multidirectional and multicomponent piecewise LFM and HFM signals
(
Elsevier Inc.
, 2018 , Article)
This paper aims at providing a more accurate description of the ambiguity domain characteristics of a piecewise multicomponent non-stationary signals with focus on piece-wise linear frequency modulated (LFM) (PW-LFM) signal ...
Oilfield scale formation and chemical removal: A review
(
Elsevier B.V.
, 2018 , Article Review)
In oil and gas industry operations, scale deposition on the surface and subsurface production equipment can cause different problems such as formation damage, loss in production, pressure reductions, and premature failure ...
Thermo-mechanical vibration of rotating axially functionally graded nonlocal Timoshenko beam
(
Springer Verlag
, 2017 , Article)
The free vibration analysis of rotating axially functionally graded nanobeams under an in-plane nonlinear thermal loading is provided for the first time in this paper. The formulations are based on Timoshenko beam theory ...
