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 ...
Experimental study on using PCMs of different melting temperatures in one cooling vest to reduce its weight and improve comfort
(
Elsevier Ltd
, 2017 , Article)
This study aims at evaluating experimentally phase change material (PCM) cooling vest performance when incorporating two types of PCM with different melting temperatures with varied PCM placement on the lower, upper, front ...
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 ...
Corruption and Economic Development: New Evidence from the Middle Eastern and North African Countries
(
Elsevier B.V.
, 2017 , Article)
This paper analyses the role of economic development in curbing corruption by focusing on political and economic freedoms for a sample of Middle Eastern and North African (MENA) countries over the period 1984-2013. In ...
Dynamic risk spillovers between gold, oil prices and conventional, sustainability and Islamic equity aggregates and sectors with portfolio implications
(
Elsevier B.V.
, 2017 , Article)
This paper investigates the time-varying equicorrelations and risk spillovers between crude oil, gold and the Dow Jones conventional, sustainability and Islamic stock index aggregates and 10 associated disaggregated Islamic ...
An efficient inverse short-time Fourier transform algorithm for improved signal reconstruction by time-frequency synthesis: Optimality and computational issues
(
Elsevier Inc.
, 2017 , Article)
This paper presents an improved signal reconstruction method based on a new inverse short-time Fourier transform (ISTFT) estimator. The main challenge addressed in this study is to design a more computationally efficient ...
A robust high-resolution time-frequency representation based on the local optimization of the short-time fractional Fourier transform
(
Elsevier Inc.
, 2017 , Article)
The Locally Optimized Spectrogram (LOS) defines a novel method for obtaining a high-resolution time-frequency (t,f) representation based on the short-time fractional Fourier transform (STFrFT). The key novelty of the LOS ...
