Advanced Materials for Energy Storage in Supercapacitors and Capacitive Water Purification
In this study, polypyrrole (PPy) prepared by chemical and electrochemical polymerization was investigated as the electrode of electrochemical supercapacitor (ES). New strategies were developed for the fabrication of nano-structured PPy and PPy based nano-composites, which included discovery of advanced anionic dopants and multi-functional nano-crystals, and development of co-dispersing agents. ...
Effects of Cognitive Control Exertion on Feeling States and Performance of a Graded Exercise Test
Exerting cognitive self-control leads to subsequent decrements in muscular and cardiovascular endurance performance. According to the Process Model of self-control, affective feeling states may account for later self-control impairments. Affective feeling states are sensitive to exercise and show a pronounced negative shift in valence at the ventilatory threshold (VT). The purpose of this study...
Strategic Communications Management in Arts Organizations
The purpose of this thesis is to determine the extent to which strategic communications
is being practiced, and its implications on organizational performance in the Canadian
arts sector. This thesis discusses the unique characteristics of not-for-profit charitable
performing arts organizations within the context of strategic communications. As a
mission-based field, the not-f...
Verification and Implementation of Embedded Systems from High-Level Models
Existing modelling tools for embedded systems analyze models that do not necessarily reflect executable code. We propose a holistic approach that includes visual modelling of the system and its environment, qualitative and quantitative verification of the model, and automated executable code generation.
For high-level modelling, we introduce pCharts, a variant of hierarchical state machines w...
Kinematic Simulation for Turbulent Particle-Laden Flows
Kinematic simulation (KS) is a means of generating a turbulent-like velocity field, in a manner that enforces an input Eulerian energy spectrum. Such models have also been applied in particle-laden flows, due to their ability to enforce spatial organization of the fluid velocity field when simulating the trajectories of individual particles. A critical evaluation of KS is presented; in particul...
THREE ESSAYS ON THE ASSOCIATION OF ECONOMIC CONDITIONS WITH THE HEALTH AND HEALTH BEHAVIOURS OF CANADIANS
This thesis comprises of three chapters that study the association of economic conditions with the health and health behaviours of adults and the health outcomes of infants.
The first chapter examines the impact of economic conditions on modifiable health behaviours, weight-related health (proxied by BMI), self-assessed mental health, life stress and general health of Canadians using data fro...
EXERCISE ENHANCES ALLOCENTRIC PROCESSING AND HIPPOCAMPAL FUNCTION IN THE ADULT BRAIN
This experiment explored whether a long-term aerobic exercise program may induce significant structural and functional changes in the hippocampus, an area of the brain that is important for spatial navigation and memory formation. Based on existing rodent studies, we hypothesize that exercise will cause a shift to allocentric processing, away from a less robust egocentric learning strategy. It ...

Reactive Extrusion of Phosphate Cross-linked Resistant Pea Starches
The primary objectives of this study were to develop an effective reactive extrusion process to produce granular phosphorylated pea starches with enhanced enzyme resistance, and examine the effects of bulk phosphorylation conditions on the morphology, physicochemical and functional properties of extruded pea starch phosphates. Two types of commercially available pea starches (NutriPea and Meelu...
A Study of Recombination Mechanisms in Gallium Arsenide using Temperature-Dependent Time-Resolved Photoluminescence
Recombination mechanisms in gallium arsenide have been studied using temperature-dependent time-resolved photoluminescence-decay. New analytical methods are presented to improve the accuracy in bulk lifetime measurement, and these have been used to resolve the temperature-dependent lifetime. Fits to temperature-dependent lifetime yield measurement of the radiative-efficiency, revealing that s...
MULTISCALE MODELING TECHNIQUES PERTAINING TO COMPOSITIONALLY GRADED MARTENSITIC STEELS
The introduction of composition gradients into the already hierarchical structure of martensitic steel leads to difficulties in modeling that arise from events occurring in the material at different length scales. In this thesis we isolate the features that are important to describing the mechanical properties of martensite and constitutively couple them through their respective length scales. ...
An Integrated Approach to Improve Data Quality
A huge quantity of data is created and saved everyday in databases from different types of data sources, including financial data, web log data, sensor data, and human input. Information technology enables organizations to collect and store large amounts of data in databases. Different organizations worldwide use data to support their activities through various applications. Issues in data qual...

The Oxidation of Fe-Mn Alloys in Carbon Dioxide-Carbon Monoxide Atmospheres at 1000°C
The oxidation kinetics of iron-manganese alloys with manganese contents up to 60 w/o exposed to carbon dioxide-carbon monoxide atmospheres at 1000°C have been determined as a function of gas composition by a gravimetric technique. The experimental conditions were chosen in order that the product of the reaction between metal and oxidizing atmosphere would be a single-phase oxide scale.
Studies on Deoxyribonucleic Acid Synthesis in Human KB Cells Infected with Human Adenovirus Type 2
Human adenovirus, type 2, was utilized to investigate its effects on the host cell population. The progression of KB cells through the various phases of the cell cycle after
infection was studied, with special emphasis of DNA metabolism. At different times after infection, the rate and the amount of viral DNA synthesized was determined and their efficiency of incorporation into virious was...
