Characterizing controls on plot-scale evapotranspiration and soil water dynamics of a constructed fen in the Athabasca Oil Sands Region, Alberta
(University of Waterloo, 2015-09-29)In the Athabasca oil sands region of the Western Boreal Plains (WBP) mining companies now recognize the importance of reclaiming peatlands, as they cover > 50% of the pre-mined regional landscape. Open-pit mining operations ... -
Characterizing current and past hydroecological conditions in shallow tundra ponds of the Hudson Bay Lowlands
(University of Waterloo, 2012-01-10)Due to accelerated climatic warming during the past fifty years, interest and concerns have been growing about changes in the ecological integrity of shallow freshwater ponds that dominate the landscape of the Hudson Bay ... -
Characterizing Distortion in Successive-Approx imation Analog-to-Digital Converters due to Off-Chip Capacitors within the Voltage Reference Circuit
(University of Waterloo, 2014-12-19)The Successive Approximation Analog-to-Digital converter (SAR-ADC) is a popular architecture due to its low power, simple design, and reasonable resolution and speed. Due to the prevalence of ADCs in modern hardware, it ... -
Characterizing Errors in Quantum Information Processors
(University of Waterloo, 2016-05-12)Error-free computation is an unattainable ideal, yet our world now contains many computers that appear error-free to their users. That such things are possible is explained by sophisticated theorems that demonstrate the ... -
Characterizing Hardness in Parameterized Complexity
(University of Waterloo, 2007-05-18)Parameterized complexity theory relaxes the classical notion of tractability and allows to solve some classically hard problems in a reasonably efficient way. However, many problems of interest remain intractable in the ... -
Characterizing Humulone Content in Beer Using Differential Mobility Spectrometry
(University of Waterloo, 2018-09-19)Beer is a complex fermented beverage and several hundreds of components have been identified erenow. Hops are extremely important to beer’s organoleptic qualities, especially bitterness. Bitterness, a distinguishing component ... -
Characterizing low-sulfide instrumented waste-rock piles: image grain-size analysis and wind-induced gas transport
(University of Waterloo, 2011-01-18)This study is part of the Diavik Waste-Rock Pile Project taking place at the Diavik Diamond Mine in the Northwest Territories, Canada. The project involves the construction of three 15m-scale low sulfide test waste-rock ... -
Characterizing Net Life Cycle Greenhouse Gas Emissions and Environmental Performance of Organic Field Crops in Ontario and Quebec
(University of Waterloo, 2023-01-20)Food production systems are at the heart of one of humankind’s greatest challenges – meeting the nutritional demands of a population expected to reach 10 billion by 2050 while limiting contributions to environmental ... -
Characterizing Noise in Quantum Systems
(University of Waterloo, 2012-07-26)In practice, quantum systems are not completely isolated from their environment and the resulting system-environment interaction can lead to information leakage from the system. As a result, if a quantum system is to be ... -
Characterizing poly-substance use and its associations with anxiety and depression among a sample of Canadian high school students
(University of Waterloo, 2022-01-05)In any given year, one in five Canadians experience mental illness. The majority of mental illnesses originate in adolescence or young adulthood. Many complex factors can contribute to this, including substance use. However, ... -
Characterizing Polymers with Complex Architecture using Pyrene Excimer Fluorescence
(University of Waterloo, 2021-09-29)This thesis combines two different models, namely the model free analysis (MFA) and the fluorescence blob model (FBM), that were used to study the conformation and internal dynamics of two highly branched macromolecules, ... -
Characterizing sediment transport and stability in remote river systems
(University of Waterloo, 2020-05-26)Canada is a large country with vast networks of linear infrastructure, such as roads and pipelines, that unavoidably intersect with waterways. Engineers must be able to characterize geomorphologic processes and channel ... -
Characterizing Sex Differences in Lipid Metabolism during an Acute, 30-Minute Bout of Moderate- Intensity Continuous (MIC) Exercise
(University of Waterloo, 2021-01-05)INTRODUCTION: Increased intramyocellular lipid (IMCL) size and storage in the subsarcolemmal region of the myocyte are associated with insulin resistance (IR) and the development of type 2 diabetes (T2D). Women have a ... -
Characterizing Sex Differences in Skeletal Muscle Anaerobic Metabolism during an Acute Bout of High Intensity Interval Exercise
(University of Waterloo, 2020-09-03)INTRODUCTION: Exercise is known to improve insulin sensitivity (IS); however, its effectiveness may be absent or blunted in women, particularly following high intensity interval (HII) training. Sex differences in anaerobic ... -
Characterizing Single Photon Emission From Quantum Dots in Nanowires
(University of Waterloo, 2019-05-28)Bright sources of highly indistinguishable single photons are desirable for diverse applications in quantum technology, including quantum cryptographic protocols, information processing, and metrology. The most common ... -
Characterizing site-specific body composition of older adults and their associations with strength, functional capacity, and metabolic health
(University of Waterloo, 2021-06-03)Background: Ageing is associated with skeletal muscle atrophy and increased intramuscular adipose tissue. Emerging evidence indicates that specific muscle groups may be largely responsible for the ageing-related degradation ... -
Characterizing Spatial and Temporal Variations in Nutrient and CO2 Dynamics Within and Across Peatlands in the Western Boreal Plain, Canada
(University of Waterloo, 2015-02-10)Peatlands are found extensively throughout the Western Boreal Plain, a region under pressure due to persistent drought conditions and industrial development (especially oil and gas, and oil sands development). Our ability ... -
