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 ...
Mitigation of Traffic Congestion Using Ramp Metering on Doha Expressway
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Ramp metering is the most effective and widely implemented strategy for improving traffic flow on freeways by restricting the number of vehicles entering a freeway using ramp meters. A ramp meter is a traffic signal ...
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ...
Characterisation of fatigue resistance of alternative pavement design for the state of Qatar
(
Taylor and Francis - Balkema
, 2014 , Conference Paper)
Asphalt mixtures have been designed in the past in the State of Qatar to safeguard against permanent deformation associated with high temperatures. These mixtures are typically designed to have low content of unmodified ...
Reveal the hidden layer via entity embedding in traffic prediction
(
Elsevier B.V.
, 2019 , Conference Paper)
The neural network-based models have been widely used in traffic prediction. They have improved accuracy and efficiency in traffic flow, speed, passenger flow, and delay. Many variables are considered to predict traffic ...
Using pavements to generate electricity
(
Elsevier B.V.
, 2019 , Conference Paper)
As part of developing a safe, efficient, and sustainable transportation infrastructure, health monitoring of pavements and bridges, as well as the monitoring of real-time roadway conditions for safety, have become increasingly ...
Status quo and critical review of PPV safe limits for subsurface construction blasting close to low-rise buildings
(
Taylor and Francis - Balkema
, 2013 , Conference Paper)
Subsurface construction blasting may result sever man-made ground vibrations.Waves generated due to detonating a charge in a solid medium like rock generate particle movement and travel at different wave velocities. As ...
A framework for construction workspace management: A serious game engine approach
(
2012 ASCE International Conference on Computing in Civil Engineering
, 2012 , Conference Paper)
Construction workspace is regarded as one of the main constraints on construction sites. Construction workspaces are generally difficult to proactively plan and manage due to the dynamic nature of a site where workspace ...
Characterisation of air voids in w-fam samples using x-ray ct imaging
(
CRC Press/Balkema
, 2018 , Conference Paper)
This study documents the use of high-resolution X-Ray Computed Tomography to characterise air void distribution in Fine Aggregate Mixtures (FAM) prepared using Warm Mix Asphalt (WMA) additives (W-FAM). Specimens were imaged ...
Geotechnical considerations on the design of piled rafts on rock
(
Research Publishing Services
, 2011 , Conference Paper)
This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ...
