Hydrothermal Treatment of Bitumen Froth at 250 °C: Impact on Bitumen Properties and Role of Clay Minerals
DownloadFall 2023
Bitumen froth produced in the hot water extraction process of mined oil sands consists of about 60 wt % bitumen, 30 wt% water and 10 wt% mineral solids. To convert the bitumen in bitumen froth into a marketable product, the water and solids need to be separated. Solvent-based froth treatment...

Postnatal development of the purinergic signaling system in the preBötzinger Complex; implications for the hypoxic ventilatory response
DownloadFall 2023
Low oxygen (hypoxia) evokes the biphasic hypoxic ventilatory response (HVR), in which carotid-body chemoreceptors trigger a rapid increase in ventilation (VE) followed by a centrally-mediated, secondary hypoxic depression of respiration (HRD) and metabolic rate (VO2) that involves adenosine. In...

Digital Twin for Production Estimation, Scheduling and Real-Time Monitoring in Offsite Construction
DownloadFall 2023
The offsite construction industry continues to rely on experience-based average production rates (i.e., average quantity per unit of time) to estimate and schedule production operations. This approach is hindered by various sources of production variability, such as machine breakdowns and...

Fall 2023
We consider stochastic generalized linear bandit (GLB) problems when the reward distributions are log-concave and subgaussian. We consider for this problem the perturbed history exploration (PHE) algorithmIn each round of its operation, PHE perturbs the observed rewards by adding fresh noise to...

Treating Waste with Waste – Calcined Bauxite Residue (CBR) as a Potential Wastewater Treatment Option for Oil Sands Process-affected Water (OSPW) and Municipal Wastewater
DownloadFall 2023
Bauxite residue is a byproduct generated during the extraction of alumina from bauxite ore. It is highly alkaline and has the potential to release toxic substances (metals) into the surrounding environment during storage. Hence, there is a growing interest in exploring the potential for metal...
