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 ...
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 ...
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 ...

Elsevier
, 2019 , Article)
Objective: To evaluate the effects of the patient–dentist relationship on dental anxiety among young adult Sudanese patients. Materials and methods: In this cross-sectional study, 864 patients attending outpatient dental ...
Hospital effect on infections after four major surgeries: Outlier and volume-outcome analysis using all-inclusive state data
(
Elsevier
, 2017 , Article)
Hospital volume is known to have a direct impact on outcomes of major surgeries. However, it is unclear if the evidence applies specifically to surgical site infections. To determine if there are procedure-specific hospital ...
Molecular scale cure rate dependence of thermoset matrix polymers
(
Elsevier B.V.
, 2016 , Article)
This manuscript demonstrates the molecular scale cure rate dependence of di-functional epoxide based thermoset polymers cured with amines. A series of cure heating ramp rates were used to determine the influence of ramp ...
