Carbon Nanotubes Dosage Optimization for Strength Enhancement of Cementitious Composites
(
Elsevier
, 2019 , Conference Paper)
Concrete is the most common used material for construction in Qatar as well as in the world. Exposure to sever environmental conditions causes physical deterioration of concrete structures and significantly affect the ...
Development of novel blend poly (Ethylene Glycol) / Poly(Ethersulfone) polymeric membrane using N-Methyl-2-Pyrollidone and dimethylformamide solvents for facilitating CO2/N2gas separation
(
Elsevier
, 2020 , Conference Paper)
Carbon dioxide (CO2) emissions have been the main cause for anthropogenic climate change. To meet the growing demand for CO2 removal, membrane separation technology using blend membranes is a promising and attractive ...
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 ...
Soil-concrete interface properties subjected to temperature changes and cycles using direct shear tests
(
American Society of Civil Engineers Library (ASCE Library)
, 2017 , Conference Paper)
Geothermal foundations (energy piles) combine the structural function of deep foundations with the ground source heat exchangers to transfer geothermal energy to superstructures. The intermittent operation of the geothermal ...
Potential of geothermal energy for electricity generation in Qatar
(
Canadian Institute of Mining, Metallurgy and Petroleum
, 2013 , Conference Paper)
There is general acceptance that climate change, which is the most important challenge facing humanity, is anthropogenic and attributed to fossil fuel consumption. Therefore, improving the performance of our existing energy ...
Recycling low grade waste heat to electricity
(
Canadian Institute of Mining, Metallurgy and Petroleum
, 2013 , Conference Paper)
Most mining and metallurgical industries produce relatively large quantities of low grade waste heat which they vent, for the most part, to the environment. To date, little is being done to recover some of this heat and ...
Geothermal energy extraction from decommissioned petroleum wells
(
International Society for Rock Mechanics
, 2014 , Conference Paper)
Abandoned wells impose enduring liabilities to petroleum companies and/or governments. However, the depth and abundance of abandoned petroleum wells make them an economically attractive source of geothermal energy. Geothermal ...
A novel technique for extraction of geothermal energy from abandoned oil wells
(2012 , Conference Paper)
This paper investigates the possibility of design and construction of a geothermal heat exchanger suitable for installation in abandoned oil wells. Based on the in-situ data collected, an amenable heat transfer numerical ...
Heat transfer analysis of regenerative thermo-mechanical refrigeration system
(
American Society of Mechanical Engineers (ASME)
, 2020 , Conference Paper)
Refrigeration systems contribute to the critical environmental concerns including global warming and ozone depletion. It is necessary to develop new systems that use renewable energy resources and waste heat to perform the ...
Engaging Engineering Students in Active Learning and Critical Thinking through Class Debates
(
Elsevier Ltd
, 2015 , Conference Paper)
Within the program of engineering, typically there are courses that are heavily dependent on mathematics and derivations of fundamental concepts. A lot of active learning can be done in these classes by using the engineering ...
