Utilization of oil wells for electricity generation: Performance and economics
(
Elsevier Ltd
, 2015 , Article)
There is a general agreement that the climate change, which is the most important challenge facing humanity, is anthropogenic and attributed to fossil fuel consumption. Therefore, deploying more renewable energy resources ...
Thermal characterization of polymer matrix composites containing microencapsulated paraffin in solid or liquid state
(
Elsevier Ltd
, 2014 , Article)
This work focuses on the study of heat transfer mechanisms in composites materials which may be used for Latent Heat Thermal Energy Storage applications. These composites contain phase change material (PCM) which can absorb ...
Thermal vibration of two-dimensional functionally graded (2D-FG) porous Timoshenko nanobeams
(
Techno Press
, 2017 , Article)
The thermo-mechanical vibration behavior of two dimensional functionally graded (2D-FG) porous nanobeam is reported in this paper. The material properties of the nanobeam are variable along thickness and length of the ...

The aim of the current study is to investigate the effect of addition of TiO2 nanoparticles and friction stir welding (FSW) parameter such as number of passes on microstructure, mechanical and tribological properties of ...
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 ...
Correlating the microstructure to mechanical properties and wear behavior of an accumulative back extruded Al-Mg2Si in-situ composite
(
Elsevier
, 2017 , Article)
The present work was conducted to study the effects of microstructural evolutions on the mechanical and wear behavior of an accumulative back extruded aluminum-based in-situ composite. The mechanical fragmentation and ...
A Robust Channel Estimation Scheme for 5G Massive MIMO Systems
(
Hindawi Limited
, 2019 , Article)
Channel state information (CSI) feedback in massive MIMO systems is too large due to large pilot overhead. It is due to the large channel matrix dimension which depends on the number of base station (BS) antennas and ...

(
Elsevier Ltd.
, 2016 , Article)
With the development of ecological science, the demand to integrate ecosystem services into ecological management is increasing. Stakeholders are interested in comparing stocks and ability to supply ecosystem services in ...
Type 2 diabetes mellitus in pregnancy: The impact of maternal weight and early glycaemic control on outcomes.
(
Elsevier
, 2018 , Article)
To study the pregnancy outcomes in women with type 2 diabetes mellitus (T2DM) and to relate these to maternal risk factors. We conducted a retrospective study of 419 women with T2DM (index group)- who attended our diabetes ...
Solar co-production of samarium and syngas via methanothermal reduction of samarium sesquioxide
