Process industries involve processes that have complex, interdependent, and sometimes uncontrollable/unobservable features that are subject to a variety of uncertainties such as operational fluctuations, sensory noises, process anomalies, human involvement, market volatility, and so forth. In the...

The Structure and Dynamics of Fish Isotopic and Trophic Niches in Natural Lakes and Constructed Fisheries Offsets in the Alberta Oil Sands
DownloadFall 2022
Habitat offsets, where damages to natural ecosystems caused by socio-economic development projects are compensated for by the construction or restoration of other ecosystems, can contribute to biological conservation when implemented properly. But, large uncertainties remain surrounding our...

Water-mediated adhesion of oil sands on solid surfaces at low temperature and possible solutions to mitigate adhesion
DownloadSpring 2022
Adhesion of frozen granular materials on solid surfaces creates various problems for surface cleaning, reduces the carrying capacity of vehicles, and increases energy consumption for inland transportation. Here in the first part of this thesis, water content demonstrates to determine the adhesion...

Techno-economic assessment of solvent-based bitumen extraction technologies including in-situ electromagnetic heating
DownloadFall 2021
The oil sands are a vast fossil fuel resource that supports the worldwide energy supply. The bitumen found in fossil deposits is too viscous to flow under reservoir conditions. For this reason, steam-based processes such as steam-assisted gravity drainage (SAGD) are used to increase the reservoir...

Calibration and Validation of a SWAT model for the quantification of water provision ecosystem service for the Conservation Area of Guanacaste
DownloadFall 2021
Water is considered a cross-cutting resource for all the ecosystem services (ES) types, namely: for the provision of drinking water and food; regulation through flood control; guarantee of a suitable habitat for fauna and flora; and inspiration for many cultures and their intangible heritage...

Monitoring Macrophage Immune Gene Expression Profiles as an Early Indicator System for Examining the Bioactivity of Oil Sands Process Affected Waters
DownloadFall 2021
Oil sands process-affected waters (OSPW) are by-products of bitumen (i.e. oil) extraction from the oil sands located in northern Alberta. These large volumes of water are held in tailings ponds and cannot be released due to their potential toxic effects. Overall, tailings ponds and mining...
