A comparison of ground vibration due to ballasted and slab tracks
(
Elsevier Ltd
, 2019 , Article)
With the development of non-ballasted track forms (often referred to as slab tracks) over the few last decades, it is important to understand their behaviour with respect to ground-borne vibration compared with the traditional ...
Literature Review of Advancements in Adaptive Ramp Metering
(
Elsevier
, 2016 , Conference Paper)
Over a period spanning more than 30 years, several ramp metering algorithms have been developed to improve the operation of freeways. Many of these algorithms were deployed in several regions of the world, and field ...
Time Delay and Cost Overrun in Qatari Public Construction Projects
(
Elsevier Ltd
, 2016 , Conference Paper)
This paper investigated cost overruns and delays in Qatari public construction projects. An extensive review of regional and international publications was conducted to get a better understanding of the problem and the ...
Digitally-tuned resolver converter
(
Elsevier B.V.
, 2009 , Article)
Sinusoidal encoders provide electrical signals related to the sine and cosine of the mechanical shaft angle θ. An analog converter is described for the linearization of these signals and hence for linear computation of θ. ...
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 ...
Mechanical and durability properties of ultra-high performance steel FRC made with discarded materials
(
Elsevier
, 2021 , Article)
This study investigates the mechanical and durability properties of 12 ultra-high performance fiber reinforced concrete (UHPFRC) mixes manufactured using alternate aggregate sources. Natural gabbro aggregates (GA), steel ...
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 ...
