Ground-borne vibration investigation by model-ling the tunnel-soil interaction using a finite element package
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
In 2013, Qatar Rail announced major rail projects that include an urban rail network for the city of Doha with lines running on the surface and underground which are expected to be in operation by 2020. Railway systems are ...
Defect based risk assessment model for prioritizing inspection of sewer pipelines
(
American Society of Civil Engineers (ASCE)
, 2018 , Conference Paper)
In presence of financial constraints and dire need for inspecting deteriorated sewer pipelines, inspection prioritization tools are required. This paper presents a defect based risk assessment model for prioritizing ...
Investigating the behavior of railroad ballast in a box test under sinusoidal & simulated train loading
(
National Technical University of Athens
, 2019 , Conference Paper)
The use of railway transportation systems has been increased throughout the years. Conventional ballasted tracks have been widely used in many countries around the world. Ballast material is the basic element in ballasted ...
Measuring construction materials price fluctuation risk
(
Canadian Society for Civil Engineering
, 2013 , Conference Paper)
Construction projects costs are believed to be highly susceptible to a combination of internal and external factors. One of these factors is the prices of construction materials and the risk of their fluctuation. This paper ...
A multi-objective genetic algorithm model for time-cost trade-off analysis of construction projects
(
Civil-Comp Press
, 2006 , Conference Paper)
Time-cost trade-off analysis is one of the most important aspects of construction project planning and control. There are trade-offs between time and cost to complete the activities of a project. Existing methods for ...
Developing a framework for calculating LCA normalization factors for the State of Qatar
(
Canadian Society for Civil Engineering
, 2013 , Conference Paper)
Life Cycle Analysis (LCA) has recently emerged as a powerful tool for assessing the environmental impact of materials, systems and processes used in building construction. With its ability to clarify the ambiguities of the ...
Planning post-disaster reconstruction efforts of damaged transportation networks
(
American Society of Civil Engineers (ASCE)
, 2009 , Conference Paper)
Planning, Reconstruction Efforts, Transportation, Network Analysis. Planning the reconstruction efforts of damaged transportation networks in the aftermath of natural disasters is a challenging task due to the limited ...
Challenges and Mitigation of Cyber Threat in Automated Vehicle: An Integrated Approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The technological development of automated vehicles opens novel cybersecurity threats and risks for road safety. Increased connectivity often results in increased risks of a cyber-security attacks, which is one of the ...
Numerical study on the effect of insulator size and shape on fouling suppression by electrodeless dielectrophoresis in submerged membrane bioreactors
(
American Institute of Physics Inc.
, 2018 , Conference Paper)
The application of obstacle dielectrophoresis has the potential to enhance membrane fouling suppression in submerged membranes bioreactors while requiring low energy consumption. In this study, the effect of the insulators ...
Impact of fines type on gas flow using 3D micro-computed tomography
(
Society of Petroleum Engineers
, 2019 , Conference Paper)
Methane hydrates are promising unconventional energy source with natural reserves above 1,000 Trillion m3. Hydrates are found in saturated sandy sediments, where multi-phase flow of gas takes place through sediment's pores, ...
