A mixed space-time and wavenumber domain model for predicting ground vibration from railway tracks
(
National Technical University of Athens
, 2015 , Conference Paper)
In this paper, a mixed model for studying ground vibration generated from surface railway tracks is presented. A ballasted track with nonlinear resilient components is modelled in the time domain using the Finite Element ...
Experimental validation of a numerical model for the ground vibration from trains in tunnels
(
DC/ConfOrg
, 2015 , Conference Paper)
Ground vibration and ground-borne noise from trains in tunnels are attracting increasing attention from researchers and engineers. They are important environmental issues related with the operation of underground networks ...
Modelling the dynamic pile-soil-pile interaction in a multi-layered half-space
(
DC/ConfOrg
, 2015 , Conference Paper)
Within the context of railway ground-borne vibration, the dynamic pile-soil-pile interaction remains an area that has not been sufficiently investigated. Whilst a number of researchers have scrutinised the vibration response ...
Effect of rail unevenness correlation on the prediction of ground-borne vibration from railways
(
DC/ConfOrg
, 2015 , Conference Paper)
This paper presents the influence of rail unevenness correlation on the predicted track and ground vibration. The study is based on an integrated railway model in the wavenumber-frequency domain with varying complexity ...
Disruption factor of asphalt mixtures
(
Taylor & Francis
, 2012 , Article)
Typically, aggregate gradation is selected to meet Superpave mix design specification; however, many Superpave mixtures have exhibited deficient field performance. The porosity of the dominant aggregate size range (DASR), ...
State-of-the-art review on sustainable design and construction of quieter pavements-Part 1: Traffic noise measurement and abatement techniques
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2016 , Article)
Noise pollution due to highway traffic has drawn the attention of transportation agencies worldwide. Noise pollution is an irritant to residents, especially in urban areas near roads with high traffic volume. In addition ...
Virtual environments for improving construction site safety
(
Taylor & Francis
, 2011 , Article)
This paper aims to present a visual simulation technique for improving construction site safety based on virtual construction environments (VCE). Additionally, the paper presents a framework to conduct true ‘what-if’ ...
Performance evaluation of full-scale sections of asphalt pavements in the State of Qatar
(
American Society of Civil Engineers (ASCE)
, 2014 , Article)
The population and economy in the State of Qatar have been increasing in the past 5 years. Accordingly, traffic loading has also increased rapidly, which affected the performance of existing roads and highways. This high ...
Integration of Captivate and JOOMLA: Online demonstration and assessment elearning resources
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2010 , Conference Paper)
The system uses Adobe Captivate [1] to create and generate the learning and assessments materials in PDF format to allow students to access the learning materials and to do the assessment interactively. Each assessment is ...
Investigation of Weather Impacts on Pedestrian Volumes
(
Elsevier B.V.
, 2016 , Conference Paper)
This study investigates the impacts of temporal and weather characteristics on pedestrian volumes in a hot climate condition. A major neighborhood located in an urban area in Doha, Qatar was chosen as a case study site. ...
