Hierarchical honeycomb auxetic metamaterials
(
Nature Publishing Group
, 2015 , Article)
Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson’s ratio. Here we develop a new class of two dimensional (2D) metamaterials with ...
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 ...
Road users' behavior at marked Crosswalks on channelized right-turn lanes at intersections in the state of Qatar
(
MDPI AG
, 2019 , Article)
At non-signalized marked crosswalks, pedestrian priority is neither well-defined nor well acknowledged by drivers. This paper presents the findings of an investigation on both driver and pedestrian behavior at non-signalized ...
Bayesian framework for fault variable identification
(
Taylor and Francis Inc.
, 2019 , Article)
In most manufacturing processes, identifying the faulty process variables that may lead to process changes is crucial for quality engineers and practitioners. There are several parametric procedures for identifying faulty ...
Nonlinear forced vibrations of sandwich smart nanobeams with two-phase piezo-magnetic face sheets
(
Springer Verlag
, 2019 , Article)
The present research is devoted to examine nonlinear forced vibration behavior of sandwich nanobeams with piezo-magnetic face sheets and rested on a hardening elastic substrate based on ordinary differential nonlocal ...
A low-cost test rig for impact experiments on a dummy head
(
Elsevier Ltd
, 2019 , Article)
Anthropomorphic test dummies are commonly used to evaluate the potential harm to humans due to dangerous scenarios, such as that due to car accidents. Furthermore, they have been used in sports to evaluate the efficacy of ...
An exact approach for the multicommodity network optimization problem with a step cost function
(
EDP Sciences
, 2019 , Article)
We investigate the Multicommodity Network Optimization Problem with a Step Cost Function (MNOP-SCF) where the available facilities to be installed on the edges have discrete step-increasing cost and capacity functions. ...
A novel in ovo model to study cancer metastasis using chicken embryos and GFP expressing cancer cells.
(
Association of Basic Medical Sciences of Federation of Bosnia and Herzegovina
, 2019 , Article)
Cancer metastasis is the leading cause of cancer-related mortality worldwide. To date, several in vitro methodologies have been developed to understand the mechanisms of cancer metastasis and to screen various therapeutic ...
Prioritisation of lean construction barriers in Qatari context: A fuzzy AHP approach
(
Inderscience Enterprises Ltd.
, 2019 , Article)
This study identifies, reviews and prioritises lean construction barriers in Qatari context. Lean has been widely adopted in manufacturing and service sectors, but its applications in construction sector are found in scarce. ...
Crashworthiness design of multi-cell tapered tubes using response surface methodology
(
Shahid Rajaee Teacher Tarining University (SRTTU)
, 2019 , Article)
In this article, crashworthiness performance and crushing behavior of tapered structures with four internal reinforcing plates under axial and oblique dynamic loadings is investigated. These structures have a tapered form ...
