The O'Nan-Scott Theorem for Finite Primitive Permutation Groups, and Finite Representability
(University of Waterloo, 2009-08-06)The O'Nan-Scott Theorem classifies finite primitive permutation groups into one of five isomorphism classes. This theorem is very useful for answering questions about finite permutation groups since four out of the five ... -
Oakland Media Library: Urban Communication Space
(University of Waterloo, 2007-10-10)As North American cities experience rapid changes in demographics, communication technology, and economy, how will urban libraries continue to hold meaning and usefulness to their publics? Investigating the position of ... -
Obedience-based Multi-Agent Cooperation for Sequential Social Dilemmas
(University of Waterloo, 2020-05-14)We propose a mechanism for achieving cooperation and communication in Multi-Agent Reinforcement Learning (MARL) settings by intrinsically rewarding agents for obeying the commands of other agents. At every timestep, agents ... -
An Obese Genotype Affects Apoptosis Related Gene Expression
(University of Waterloo, 2009-01-15)Apoptosis is a genetically regulated form of cell death that occurs when the cell is exposed to physiological, pathogenic, or cytotoxic stimuli. Unregulated apoptosis (too much or too little apoptosis) at any time from ... -
An Obese Genotype Affects the Sphingolipid Signaling Pathway
(University of Waterloo, 2008-01-24)Sphingolipids are important signaling molecules regulating cell growth, cell death and differentiation, thus making them important molecules in determining the fate of a cell and in the pathogenesis of chronic illnesses. ... -
Obesity associated colon tumorigenesis: An assessment of tumor phenotype
(University of Waterloo, 2006)Colon cancer and obesity are two significant and related pathological states with multiple etiological factors. In this dissertation, it was hypothesized that tumor growth is accelerated in the altered state of obesity ... -
Obesity, Physical Activity and Sedentary Behaviour Among Canadian First Nations Youth: An Exploration of Associated Factors and Evaluation of a School Sports Program
(University of Waterloo, 2016-01-19)Background: Secondary to inequities in several determinants of health, Canadian Aboriginal youth are affected by a higher prevalence rate of obesity and chronic disease than the general population. While the factors ... -
Object Histories in Java
(University of Waterloo, 2010-04-30)Developers are often faced with the task of implementing new features or diagnosing problems in large software systems. Convoluted control and data flows in large object-oriented software systems, however, make even simple ... -
'The Objectifying Gaze': The Role of Adaptation in Perceptions of Gender on Television
(University of Waterloo, 2021-07-06)For too long, adaptation studies has been limited to film and focused on adaptation as a product (i.e. the transformation of a novel into a film), but expanding the field to television and emphasizing the process of ... -
Objective assessment of Visual acuity in infants
(University of Waterloo, 2013-08-06)Purpose Early detection of abnormal visual acuity (VA) is crucial in the identification and management of ocular and visual abnormalities in infants. Currently, the Teller Acuity Cards (TACs) are considered the gold ... -
Objective Quality Assessment and Optimization for High Dynamic Range Image Tone Mapping
(University of Waterloo, 2014-06-06)Tone mapping operators aim to compress high dynamic range (HDR) images to low dynamic range ones so as to visualize HDR images on standard displays. Most existing works were demonstrated on specific examples without being ... -
Objective Validation of Airport Terminal Architecture using Agent-based Simulations
(University of Waterloo, 2021-05-25)This thesis explores how airport terminal architecture is tested before it is built. The purpose of testing is to make sure an architectural layout aligns with the rest of the airport’s systems. The design of a terminal ... -
Observability and Economic aspects of Fault Detection and Diagnosis Using CUSUM based Multivariate Statistics
(University of Waterloo, 2010-12-08)This project focuses on the fault observability problem and its impact on plant performance and profitability. The study has been conducted along two main directions. First, a technique has been developed to detect and ... -
Observation of Resonant Electric Dipole-Dipole Interactions Between Cold Rydberg Atoms Using Microwave Spectroscopy
(University of Waterloo, 2006)This thesis reports the first observation of the resonant electric dipole-dipole interaction between cold Rydberg atoms using microwave spectroscopy, the observation of the magnetic field suppression of resonant interactions, ... -
Observations of Atmospheric Gases Using Fourier Transform Spectrometers
(University of Waterloo, 2007-10-23)Remote sensing of atmospheric gases improves our understanding of the state and evolution of the Earth’s environment. At the beginning of the thesis, the basic principles for the retrieval of concentrations of atmospheric ... -
Observations of Moderate to Deep Seasonal Snow in Agricultural Fields with a Radar Scatterometer at Ku- and X-band Frequencies
(University of Waterloo, 2015-10-26)The water contained within a snowpack, or the snow water equivalent (SWE), is very important to the hydrological cycle and to populations who depend on it for drinking, agriculture and industry. Measuring SWE over large ... -
Observers on linear Lie groups with linear estimation error dynamics
(University of Waterloo, 2012-09-20)A major motivation for Lie group observers is their application as sensor fusion algorithms for an inertial measurement unit which can be used to estimate the orientation of a rigid-body. In the first part of this thesis ... -
