Pedestrians' Speed Analysis at Signalized Crosswalks
(
Elsevier B.V.
, 2018 , Conference Paper)
Pedestrian speed is essential for designing signal timings as well as for understanding pedestrian safety issues. This paper presents analysis of three types of pedestrian speeds (entry speed, crossing speed, and exit ...
Comparison of SimTraffic and VISSIM Microscopic Traffic Simulation Tools in Modeling Roundabouts
(
Elsevier B.V.
, 2015 , Conference Paper)
Abstract SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation ...

(
Elsevier
, 2018 , Article)
Doha, the capital of the State of Qatar, has faced enormous economic growth and rapid urban
transformation over the last few decades. More recently, this has been accentuated by the construction
of major urban public ...
Engaging Engineering Students in Active Learning and Critical Thinking through Class Debates
(
Elsevier Ltd
, 2015 , Conference Paper)
Within the program of engineering, typically there are courses that are heavily dependent on mathematics and derivations of fundamental concepts. A lot of active learning can be done in these classes by using the engineering ...
Self-organized TiO2 nanotube layer on Ti–6Al–7Nb for biomedical application
(
Elsevier B.V.
, 2015 , Article)
In the present study, a self-organized nanotube TiO2 layer on Ti–6Al–7Nb was fabricated. The influence of acidic electrolytes including glycerol (G) and ethylene glycol (EG) on the anodization, microstructural features and ...
Constitutive analysis for the quantification of hardness decay in a superlattice CrN/NbN hard-coating
(
Elsevier B.V.
, 2015 , Article)
In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ...
Axial crushing behavior and energy absorption efficiency of corrugated tubes
(
Elsevier, Ltd
, 2014 , Technical Report)
This paper presents the effect of corrugations on the crushing behavior, energy absorption, and failure mode of circular aluminum tubes. Experimental investigations were carried out on five geometrical types of corrugated ...
Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser
(
Elsevier
, 2016 , Article)
In this study, we present a numerical investigation of active surge control and performance improvement for an aero engine centrifugal compressor (NASA CC3) using self-recirculating bleed slots with different bleeding ...
Time-domain simulation of second-order irregular wave diffraction based on a hybrid water wave radiation condition
(
Elsevier
, 2016 , Article)
A time-domain second-order method is presented to simulate three-dimensional wave–body interaction. In the approach, Taylor series expansions are applied to the free surface boundary conditions, and a Stokes perturbation ...
Random number of units for K-out-of-n systems
(
Elsevier
, 2017 , Article)
This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ...
