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 ... -
Observe, Predict, Adapt: A Neural model of Adaptive Motor Control
(University of Waterloo, 2024-01-24)Biological control systems have evolved to perform efficiently in an environment characterized by high uncertainty and unexpected disturbances, while relying on noisy sensors and unreliable actuators. Despite these ... -
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 ... -
Observing Scattering Mechanisms of Bubbled Freshwater Lake Ice Using Polarimetric RADARSAT-2 (C-Band) and UW-Scat (X- and Ku-Bands)
(IEEE, 2018-05-01)A winter time series of ground-based (X- and Ku-bands) scatterometer and spaceborne synthetic aperture radar (SAR) (C-band) fully polarimetric observations coincident with in situ snow and ice measurements are used to ... -
Obstacle Avoidance in Intelligent Assisted Walking Devices for Improving Mobility Among Seniors with Cognitive and Visual Impairments
(University of Waterloo, 2016-01-25)Current research in walkers and rollators with integrated intelligent computing and robotic components shows promise in treatment, management and rehabilitation of a variety of ailments and disorders such as stroke, Alzheimer ... -
Obstacles and Opportunities in Planning and Implementing Integrated Sustainable Municipal Solid Waste Management (ISMSWM) in Kuwait – a Gulf Cooperation Council (GCC) Country
(University of Waterloo, 2020-08-31)The conventional municipal solid waste (MSW) management approach focuses on collection, transportation and final disposal, while at the same time neglecting the prevention of waste and recycling. The conventional approach ... -
Obus: Intent and Inhabitation
(University of Waterloo, 2019-09-23)First proposed by Le Corbusier for the city of Algiers in 1932 but never built, the Plan Obus is Le Corbusier’s ultimate city planning project. The forerunner of the megastructures projects of the 1960s, it sits squarely ... -
Occlusion-Ordered Semantic Instance Segmentation
(University of Waterloo, 2023-08-23)Conventional semantic ‘instance’ segmentation methods offer a segmentation mask for each object instance in an image along with its semantic class label. These methods excel in distinguishing instances, whether they belong ... -
Occupational Health Research in Workplaces Transitioning from Modernity to Post-Modernity
(University of Waterloo, 2024-04-11)Occupational health is a complex concept and the offspring of a marriage between law and science. The marriage is influenced by multiple extended families or networks, which act together and in opposition to create policy ... -
Occupational Prestige of Canadian Professions in the New Economy
(University of Waterloo, 2008-12-19)Canadian professions have, paradoxically, lost prestige at least in a relative sense, despite being the prototype for the expanding new economy. The early 1990s saw a transition from the old economy to a new economy ... -
The Occurrence and Behavior of Rainfall-Triggered Landslides in Coastal British Columbia
(University of Waterloo, 2009-06-19)This thesis seeks to analyze the occurrence and behavior of rainfall-triggered landslides in coastal British Columbia. In particular, it focuses on the analysis of landslide temporal and spatial distributions occurrence ... -
Occurrence and Seasonal Variability of Selected Pharmaceuticals in Southern Ontario Drinking Water Supplies
(University of Waterloo, 2007-04-27)The presence and seasonal variability of human and veterinary pharmaceuticals in surface water (raw water) and treated water samples from two drinking water facilities in Southern Ontario was investigated. Water samples ... -
Occurrence, Fate, and Mobility of Antibiotic Resistant Bacteria and Antibiotic Resistance Genes among Microbial Communities Exposed to Alternative Wastewater Treatment Systems
(University of Waterloo, 2012-08-29)The ubiquitous nature of antibiotic resistance and antibiotic resistance genes (ARGs) among environmental pathogens from a variety of wastewater effluents, suggests that the aquatic environment, and specifically alternative ... -
Occurrent Contractarianism: A Preference-Based Ethical Theory
(University of Waterloo, 1995)There is a problem within contractarian ethics that I wish to resolve. It concerns individualpreferences. Contractarianism holds that morality, properly conceived, can satisfy individualpreferences and interests better ... -
Octupolar Ordering in the b>0 Bilinear-Biquadratic Heisenberg Pyrochlore
(University of Waterloo, 2019-01-25)We investigate the bilinear-biquadratic Heisenberg model on the pyrochlore lattice. While negative biquadratic couplings result in a first-order transition into a nematic ordered state with spins aligned mutually ... -
