A continuum model with a percolation threshold and tunneling-assisted interfacial conductivity for carbon nanotube-based nanocomposites
(
American Institute of Physics Inc.
, 2014 , Article)
A continuum model that possesses several desirable features of the electrical conduction process in carbon-nanotube (CNT) based nanocomposites is developed. Three basic elements are included: (i) percolation threshold, ...
Bird strike analysis on a typical helicopter windshield with different lay-ups
(
Korean Society of Mechanical Engineers
, 2014 , Article)
In the current paper, bird strike to a typical helicopter windshield is investigated using smoothed particles hydrodynamic (SPH) finite element method. Five types of lay-ups in a windshield (single layer stretch acrylic, ...
A three dimensional extended Arlequin method for dynamic fracture
(
Elsevier B.V.
, 2015 , Article)
We propose a concurrent multiscale method for fracture coupling two three-dimensional continuum domains. Fracture in both domains is treated by the extended finite element method. The coupling is based on the Arlequin ...
Heterogeneities in Polymer Structural and Dynamic Properties in Graphene and Graphene Oxide Nanocomposites: Molecular Dynamics Simulations
(
Wiley-VCH Verlag
, 2017 , Article)
The effect of graphene (G) and graphene oxide (GO), used as the nanofiller in polymer nanocomposites (NC), on the structural and dynamic properties of polymer chains, has been studied by means of molecular dynamics (MD) ...
First and Last Triggering Event Approaches for Replacement with Minimal Repairs
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
To make effective use of a running system, this paper proposes that, when replacement times could be scheduled at a planned time T of operation, and at a number N of minimal repairs, the newly proposed approach of whichever ...
What is Middle Maintenance Policy?
(
John Wiley and Sons Ltd
, 2016 , Article)
The main purpose of this paper is to propose several new maintenance policies that can be performed at suitable middle times for trivariate preventive maintenance scenarios. Firstly, characteristics and limitations for the ...

(
MDPI
, 2018 , Article)
This paper presents the bandwidth enhancement and frequency scanning for fan beam array antenna utilizing novel technique of band-pass filter integration for wireless vital signs monitoring and vehicle navigation sensors. ...
Microstructure, thermal and mechanical response of AZ51/Al2O3 nanocomposite with 2 wt.% Ca addition
(
Elsevier, Ltd
, 2013 , Article)
In the present study, new AZ51/Al2O3–2Ca magnesium nanocomposite was successfully synthesized by simultaneously adding 2wt.% aluminum, 2wt.% Ca and 1.5vol.% nanosized Al2O3 (50nm) into AZ31 matrix using a disintegrated ...
An empirical study on lean awareness and potential for lean implementations in Qatar industries
(
Springer-Verlag London Ltd
, 2016 , Article)
In this study, an investigation on the level of recognition of lean concepts, principles, tools, and techniques in different industrial sectors in Qatar was carried out. The general aim of the study was to determine lean ...
Damping and vibration response of viscoelastic smart sandwich plate reinforced with non-uniform Graphene platelet with magnetorheological fluid core
(
Techno Press
, 2019 , Article)
This study considers the instability behavior of sandwich plates considering magnetorheological (MR) fluid core and piezoelectric reinforced facesheets. As facesheets at the top and bottom of structure have piezoelectric ...
