Multiple-runway aircraft sequencing problems using mixed-integer programming
(
Institute of Industrial Engineers
, 2012 , Conference Paper)
We examine aircraft sequencing problems over multiple runways, under mixed mode operations, with the objective of minimizing the total weighted tardiness of aircraft landings and departures. A mixed-integer programming ...
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 ...
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 ...
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 ...
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 ...
Centrifugal Compressor Spiral Dry Gas Seal Simulation Working at Reverse Rotation
(
Elsevier Ltd
, 2013 , Conference Paper)
Unidirectional dry gas seal may experiences reverse rotation when equipped in a centrifugal compressor. This paper describes how the reverse rotation effects on the spiral unidirectional dry gas seal performance and pressure ...
Three Dimensional Computational Study for Spiral Dry Gas Seal with Constant Groove Depth and Different Tapered Grooves
(
Elsevier Ltd
, 2013 , Conference Paper)
The three dimensional simulation for dry gas seal with constant depth spiral grooves and with different taper grooves is done using ANSYS FLUENT CFD code. Grid independence study and code validation are done with experimental ...
Optimizing multi-objective dynamic facility location decisions within green distribution network design
(
Elsevier
, 2014 , Conference Paper)
Despite the surge of sustainable economic development which inspires corporations to optimize investment on environmental-friendly infrastructural facilities, limited pragmatic evidences are observed in product-service ...
