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 ...
A branch-and-price algorithm for the two-stage guillotine cutting stock problem
(
Palgrave Macmillan Ltd.
, 2013 , Article)
We investigate the two-stage guillotine two-dimensional cutting stock problem. This problem commonly arises in the industry when small rectangular items need to be cut out of large stock sheets. We propose an integer ...
PS/TiO2 (polystyrene/titanium dioxide) composite nanofibers with higher surface-to-volume ratio prepared by electrospinning: Morphology and thermal properties
(
John Wiley & Sons, Ltd.
, 2013 , Article)
Polystyrene (PS)/Titanium dioxide (TiO2) composite nanofibers were prepared by electrospinning of PS/TiO2 solution in N,N-dimethylformamide (DMF). The effect of PS and TiO2 concentration on the morphology and thermal ...
Improved bounds for hybrid flow shop scheduling with multiprocessor tasks
(2013 , Article)
In this paper, we investigate the problem of minimizing makespan in a multistage hybrid flow-shop scheduling with multiprocessor tasks. To generate high-quality approximate solutions to this challenging NP-hard problem, ...
Key performance indicators (KPIs) for evaluation of energy conservation in buildings
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
The main objectives of this paper are to: identify key performance indicators (KPIs) related to intelligent buildings (economical, environmental, reliability, and quality), and; propose a simulation framework for evaluation ...
An experimental investigation into mechanical behavior of hybrid and nonhybrid composite semi-elliptical springs
(
Elsevier, Ltd
, 2013 , Article)
This study introduces a new composite semi-elliptical suspension spring by utilizing fiber reinforced composite strength in principal direction instead of shear direction. Three types of composites were tested, namely, ...
An assignment-based lower bound for a class of two-machine flow shop problems
(2013 , Article)
We present an assignment-based lower bound that is valid for a wide class of two-machine flow shop problems with a regular additive performance criterion. We provide empirical evidence that this new bound consistently ...
Enhanced compact models for the connected subgraph problem and for the shortest path problem in digraphs with negative cycles
(2013 , Article)
We investigate the minimum-weight connected subgraph problem. The importance of this problem stems from the fact that it constitutes the backbone of many network design problems having applications in several areas including ...
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 ...
