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 ...
Preventive replacement policies with aging failure and third-part damage
(
SciTePress
, 2016 , Conference Paper)
In general, corrosions, degrading the mechanical strength of pipelines gradually with its age in a stochastic way, is the predominant cause of pipeline leaks. In addition, the third-part damage is the leading cause of ...
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 ...
Study on the effects of tool tile angle, offset and plunge depth on friction stir welding of poly(methyl methacrylate) T-joint
(
SAGE Publications Ltd
, 2019 , Article)
The effects of tilt angle (TTA), plunge depth (TPD) and offset (TO) of tool in friction stir welding of poly(methyl methacrylate) T-joint were investigated. To understand better the effects of process parameter, thermomechanical ...
Replacement policies for periodic damage models
(
International Society of Science and Applied Technologies
, 2016 , Conference Paper)
A new periodic damage model for preventive replacement policies is proposed in this paper, where the damage produced by shocks is only measured at periodic times, without considering the mathematical models of the stochastic ...
Age replacement models: A summary with new perspectives and methods
(
Elsevier Ltd
, 2017 , Article Review)
Age replacement models are fundamental to maintenance theory. This paper summarizes our new perspectives and hods in age replacement models: First, we optimize the expected cost rate for a required availability level and ...
Elastic properties of chiral, anti-chiral, and hierarchical honeycombs: A simple energy-based approach
(
Elsevier Ltd
, 2016 , Article)
The effects of two geometric refinement strategies widespread in natural structures, chirality and self-similar hierarchy, on the in-plane elastic response of two-dimensional honeycombs were studied systematically. Simple ...
Nonlocal damage modelling in clay/epoxy nanocomposites using a multiscale approach
(
Elsevier
, 2016 , Article)
This study proposed a concurrent multiscale method to model damage in clay/epoxy nanocomposites. The method uses a nonlocal damage formulation to regularize the damage model. The multiscale method used, is based on the ...
