Magneto-electric effects on nonlocal nonlinear dynamic characteristics of imperfect multi-phase magneto-electro-elastic beams
(
Elsevier
, 2020 , Article)
This paper studies nonlinear dynamic characteristics of a nonlocal two-phase piezo-magnetic beam including geometric imperfections by considering piezoelectric reinforcement scheme. The piezoelectric reinforcement can cause ...
Investigating nonlinear vibrations of multi-scale truncated conical shell segments with carbon nanotube/fiberglass reinforcement using a higher order conical shell theory
(
SAGE Publications Ltd
, 2021 , Article)
This research deals with the nonlinear vibration analysis of functionally graded carbon nanotubes and fiber-reinforced composite truncated conical shell segments based upon third-order shear deformation theory. A detailed ...
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 ...
A robust resource allocation scheme for device-to-device communications based on Q-Learning
(
Tech Science Press
, 2020 , Article)
One of the most effective technology for the 5G mobile communications is Device-to-device (D2D) communication which is also called terminal pass-through technology. It can directly communicate between devices under the ...
Collaborative Wireless Power Transfer in Wireless Rechargeable Sensor Networks
(
Hindawi Limited
, 2020 , Article)
Wireless power transfer techniques to transfer energy have been widely adopted by wireless rechargeable sensor networks (WRSNs). These techniques are aimed at increasing network lifetime by transferring power to end devices. ...
Geometrically nonlinear vibration analysis of eccentrically stiffened porous functionally graded annular spherical shell segments
(
Taylor and Francis Ltd.
, 2022 , Article)
This article investigates nonlinear free vibrations of porous functionally graded (FG) annular spherical shell segments surrounded by elastic medium and reinforced by circumferential stiffeners. Porous FG material contains ...
Effect of multi-pass friction stir processing on the microstructure, mechanical and wear properties of AA5083/ZrO2 nanocomposites
(
Elsevier Ltd
, 2017 , Article)
In this study, multi-pass friction stir processing using zirconia nanoparticles was performed on AA5083 sheets to fabricate surface nanocomposites. Effect of using different number of passes on the microstructure, ...
