Qatar national MUSEUM-Transit oriented development: The masterplan for the urban regeneration of a 'green TOD'
(
Elsevier B.V.
, 2019 , Article)
Over the past two decades, a growing number of communities have pursued light rail transit (LRT) and Transit-Oriented Developments (TODs) as part of an integrated transportation and land use strategy to revitalize and/or ...
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 ...
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. ...
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 ...
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 ...
Design and testing of a hybrid electromagnetic damping device for automotive applications
(
Elsevier
, 2024 , Article)
This study proposes a new design concept for combining a viscous fluid damper (VFD) with an eddy current damper (ECD). Three main concepts were thoroughly discussed: the magnetic system, the conductive material, and the ...
Nonlinear analysis of shell structures using image processing and machine learning
(
Elsevier
, 2023 , Article)
In this paper, we propose a novel approach to solve nonlinear stress analysis problems in shell structures using an image processing technique. In general, such problems in design optimisation or virtual reality applications ...
Gas turbine failure classification using acoustic emissions with wavelet analysis and deep learning
(
Elsevier
, 2023 , Article)
Compared to vibration monitoring, acoustic emission (AE) monitoring in gas turbines is highly sensitive to changes that do not involve whole-body motion, such as wear, rubbing, and fluid-induced faults. AE signals captured ...
