Fall 2020
This thesis develops a time averaged model (TAM) and a dynamic phasor model (DPM) of a generalised modular multilevel converter (MMC) structure that can be used to represent four different MMC topologies. These four topologies include two different classes of next generation MMCs that are...

Modeling, Analysis, and Stabilization of a Single-Stage Utility-Scale Photovoltaic System with Reduced DC-Link Capacitance
DownloadFall 2020
A single-stage utility-scale photovoltaic (PV) system is usually interfaced with the host grid via a central voltage-source converter (VSC). Recently, due to their reliability, dc-link film capacitors are favored over electrolytic capacitors in grid-connected VSC applications. However, the...

Fall 2019
Lateral–torsional buckling is a stability-related failure mode of unbraced or insufficiently braced flexural members. In recent years, several concerns have been raised regarding the adequacy of the Canadian steel design standard, CSA S16-14, in characterising the lateral–torsional buckling...

Novel feed enzyme delivery method: Binding exogenous feed enzymes to Bacillus spores to improve enzyme stability and total tract digestibility
DownloadFall 2018
The effects of binding feed enzymes to Bacillus subtilis (strain RK28) spores on enzyme stability and digestion in cattle were studied in comparison to unbound enzymes. Optimal conditions for adsorbing six different enzymes (α-amylase, β-glucanase, feruloyl esterase, phytase, purified xylanase,...

Study of Methylammonium Lead Triiodide Intrinsic Stability and Solid-Solution behaviour in Mixed Halide Perovskite Systems
DownloadFall 2018
Askar, Abdelrahman Mostafa Mohamed Sanad
Over the last nine years, a new class of materials named lead halide perovskite has made a paradigm shift in the field of optoelectronic solution-processable low-cost and high-efficiency devices, with outstanding accomplishments especially in the ever-growing field of renewable solar energy...

Characterization of magnetic nanoparticles as contrast agents and their application for quantitative magnetic susceptibility monitoring of the waterflooding of heavy oil in real time
DownloadSpring 2018
Waterflooding is one enhanced oil recovery process used in heavy oil reservoirs such as at Cold Lake in North-Eastern Alberta. However, little has been published in terms of imaging heavy oil waterfloods, mainly due to the similar densities of water and heavy oil, which makes it difficult to...

Modeling, Analysis and Advanced Control of Voltage- and Current-Source Converters in Renewable Energy-Based Active Distribution Systems
DownloadSpring 2016
This thesis addresses the integration of renewable energy resources into the grid-connected and isolated distribution systems using voltage- and current-source converters. Motivated by its promising potential and attractive features, a one-stage current-source converter (CSC) is selected as an...

Development of Poly(ethylene oxide)-block-poly(ε-caprolactone) based Micelles for Tumor Targeted Drug and siRNA Delivery
DownloadFall 2015
The use of nanotechnology has made significant advancements in cancer diagnosis and treatment. Polymeric micelles are a relatively new generation of nanocarriers mostly intended for the delivery of hydrophobic drugs. In this thesis, our objective was to develop an optimized polymeric micellar...

Fall 2014
Developing a simple, general, and isothermal self-replicating system is one of the key requirements for a simplified detection platform for nucleic acid sequences specific to a disease causing microrganism. One of the challenges in achieving nucleic-acid templated isothermal amplification is that...

Reading Rawls’s Lectures on Hobbes’s Leviathan: Pluralism, Stability, and Political Consensus
DownloadSpring 2014
This work examines Rawls’s lectures on Hobbes, which are delivered at a time when Rawls is developing his political liberalism. It especially seeks to question the foundations of Rawls’s interpretation of Hobbes’s Leviathan as presenting a core “political” doctrine based around prudential egoism....
