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 ...
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, ...
Numerical study of the attenuation properties of viscoelastic metamaterials
(
Institute of Physics Publishing
, 2018 , Conference Paper)
Metamaterials (MMs) are materials engineered to have a property that is not found in nature. In this study, one-dimensional MMs is investigated, particularly that with a functional elastic wave band gaps where propagation ...
Experimental study of the attenuation properties of metal-viscoelastic bi-layered materials
(
Institute of Physics Publishing
, 2018 , Conference Paper)
Phononic crystals (PCs) are multi-layered materials with functional elastic wave band gaps where propagation of vibration within these band gaps is restricted. PCs have vibration attenuation properties dependent on their ...
Comparing eurocode 2 prestress loss estimations to strains measured on a pretensioned bridge beam
(
CRC Press/Balkema
, 2019 , Conference Paper)
The implementation of Eurocode 2 (EC2) for the design of concrete structures in South Africa in the near future is pending and necessitates refined understanding of EC2’s prediction models; including prestress losses and ...
NAVIGATION IN INDOOR VOXEL MODELS
(
Copernicus GmbH
, 2019 , Conference Paper)
The paper proposes to use voxel models of building interiors to perform indoor navigation. The algorithms can be purely geometrical, not relying on semantic information about different building elements, such as floors, ...
Bond and shear-strengthening performance of FRCM composites
(
ISEC Press
, 2019 , Conference Paper)
This paper is aimed at studying the bond and shear-strengthening performance of fabric reinforced cementitious matrix (FRCM) systems. Three FRCM systems were compared, namely, polyparaphenylene benzobisoxazole (PBO)-FRCM, ...
Where Is Qatar from Complete Streets?
(
Springer Verlag
, 2019 , Conference Paper)
In Qatar, it is perceived that the country's street system should be improved. Traffic crashes and congestion are seen as a threat to the safety of the community in Qatar and a negative element that detracts from the ...
