A comparative analysis of experimental and numerical investigations of composite tubes under axial and lateral loading
(2010 , Article)
Quasi-static tests are performed in order to determine the crash behavior of composite tubes. The specimens are made from woven fiber carbon/epoxy. The crash experiments show that the tubes crushed in a progressive manner ...
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 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 ...
Influence of TiO2 nanoparticles incorporation to friction stir welded 5083 aluminum alloy on the microstructure, mechanical properties and wear resistance
(
Elsevier
, 2017 , Article)
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 ...
Lifted polynomial size formulations for the homogeneous and heterogeneous vehicle routing problems
(
Elsevier B.V.
, 2017 , Article)
We propose compact formulations for the symmetric and asymmetric capacitated vehicle routing problems. These formulations are obtained by lifting, using the Reformulation-Linearization Technique, a novel polynomial size ...
Research frontiers in sustainable development of energy, water and environment systems in a time of climate crisis
(
Elsevier Ltd
, 2019 , Article)
Sustainable energy conversion and management processes increasingly require an integrated approach, especially in the context of addressing the climate crisis. This editorial puts forth related research frontiers based on ...
Regression models for performance prediction of counter flow dew point evaporative cooling systems
(
Elsevier Ltd
, 2019 , Article)
Practitioners take more interest in the output conditions of cooling systems than the details of the processes. In this study, regression models are developed that relate input parameters, including operational and geometrical ...
