Mining companies are investing in fewer but larger equipment, and downtime associated with larger equipment now represents a higher percentage of operational capacity loss. Thus, it is essential to frequently and accurately monitor the health of this equipment to avoid unscheduled breakdowns and...

One of the current technologies used by the oil sands industry to reduce the volume of fluid fine tailings and create a dry landscape is production of CT (Composite Tailings) and NST (Non-Segregating Tailings). CT and NST are engineered tailings streams obtained by recombination of fines (MFT or...

Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...

The accumulation of huge amount of oil sands process water (OSPW) in tailing ponds has shown a serious threat to the local public health for their potential to contaminate surface and groundwater. Naphthenic acids (NAs) are considered to be one of the most important toxic compounds present in...

This thesis extends the current research on graph theory-based techniques to meet the needs of planners of multimodal transit networks. Graph theory was originally developed in the 1700s to study transportation systems although it was not adapted to study public transportation networks until the...

Numeric data for earth sciences often represent fractions or percentages of a whole, such as the chemical or mineralogical composition of a rock. The individual components are non-negative and have a constant sum of 100%. Satisfying these constraints at unsampled locations after estimation or...
