A General Framework of Optimal Stochastic Optimization with Dependent Data: Multiple Optimality Guarantee, Sample Complexity, and Tractability
DownloadSpring 2023
We consider stochastic optimization in settings where the distribution of unknown parameters is observable only through finitely dependent training samples. Using the Sample Averaging Approximation ({SAA}), we specifically study the data-driven procedure in which, instead of receiving samples...

There is a fundamental need to improve grit removal techniques for municipal wastewater treatment plants (WWTP) to meet newer effluent standards and to deal with the rapid growth of urbanization and industrialization. In response to this need, secondary and tertiary treatment processes are being...

In many applications, it is desired to separate unwanted fine particulates from a liquid by gravity settling. An efficient separation, however, will be feasible only if a combination of aggregation and sedimentation occurs. To understand the kinetics of such a process, a mathematical model that...

At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids whether suspended in aqueous or non-aqueous liquids continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

This thesis explored the properties of asphaltene nano-aggregates in crude oil and toluene based solutions and fouling at process furnace temperatures, and the links between these two phenomena. The link between stability of asphaltenes at ambient conditions and fouling at the conditions of a...

Colloidal-collector interactions are of fundamental importance in separation and filtration technologies. Here, the effect of collector grains on the behavior of colloidal particles was studied in two different experimental systems, i.e., column studies with stationary collectors and batch mixing...

Concentration and Mixing Effects on the Production of Amine Hydrochloride Salts in a Confined Impinging Jet Reactor
DownloadFall 2013
A Confined Impinging Jet Reactor (CIJR) was used to react 4, 4’-methylene dianiline (MDA) with hydrogen chloride (HCl) in order to study formation of the aminehydrochloride (AHC) salts, unwelcome byproducts in the manufacture of polyurethanes. The effects of several processing variables (local...

In oil sands extraction, the removal of heavy materials from a bitumen feed is often facilitated by solvent addition treatment processes. These processes mix solvent with bitumen feed to cause the precipitation of heavy products. The settling properties of these heavy products as they separate...

The current work presents the results of an experimental study on the effects of submergence on the performance of a submerged hydraulic jump with baffle blocks downstream of a sluice gate. A wide range of Froude numbers, submergence factors, and block sizes, locations and arrangements were...

Identifying seasonal Lake Sturgeon (Acipenser fulvescens) movement patterns and habitat selection in the South Saskatchewan River Basin
DownloadFall 2016
Lake Sturgeon (Acipenser fulvescens Rafinesque 1817) have experienced population declines throughout their range. In Alberta, low density age-class distributions, irregular recruitment, critically low spawning potential ratios and other factors led to a 2007 designation of “Threatened” for this...
