Robustness in Automatic Physical Database Design
(University of Waterloo, 2007-08-17)Automatic physical database design tools rely on ``what-if'' interfaces to the query optimizer to estimate the execution time of the training query workload under different candidate physical designs. The tools use these ... -
Robustness in Dimensionality Reduction
(University of Waterloo, 2016-04-14)Dimensionality reduction is widely used in many statistical applications, such as image analysis, microarray analysis, or text mining. This thesis focuses on three problems that relate to the robustness in dimension ... -
A Rock Borehole Packer System for Identifying Hydraulically Active Fractures Under Natural Gradient Flow
(University of Waterloo, 2008-05-27)To improve capabilities for understanding and predicting contaminant migration in fractured rock there is need for better field methods to identify the fractures that have active groundwater flow. Current methods have ... -
Rock Stability under Different Fluid Flow Conditions
(University of Waterloo, 2003)It is widely known in oil industry that changes in fluid flow conditions such as water breakthrough or unsteady flow due to well shut-in can lead to sand destabilization, with a possible consequent sand production. In ... -
Rod Coating MoS2 Films and Silver Nanowire Electrodes for 2D Material-based Devices
(University of Waterloo, 2023-09-19)Two-dimensional materials have garnered significant attention in the research community due to their unique physical and electrical properties. Among these materials, molybdenum disulfide (MoS2) is a promising candidate ... -

The role of ACC deaminase in plant growth promotion by the endophytic bacterium Burkholderia phytofirmans PsJN
(University of Waterloo, 2008-08-01)The endophytic bacterium Burkholderia phytofirmans PsJN has been previously shown to promote plant growth. This bacterium produces siderophores, indoleacetic acid (IAA) and the enzyme 1-aminocyclopropane-1-carboxylate (ACC) ... -
The Role of Activities of Daily Living in Healthy Vascular Aging
(University of Waterloo, 2022-01-05)Normal aging leads to endothelial dysfunction and arterial stiffening implicated in cognitive decline. Cerebral blood flow also declines with aging. Elevated blood flow during exercise produces laminar shear stress which ... -
The Role of Acute High-Intensity Interval Exercise as a Potential Facilitator for Improved Executive Functions and Affect in Healthy Young and Older Adults
(University of Waterloo, 2021-01-06)A single bout of aerobic exercise has been shown to improve executive functions and affect across the lifespan. The magnitude of improvements appear to be influenced by exercise-dependent factors, including the intensity ... -
The Role of Affect in Commercializing New Ideas
(University of Waterloo, 2008-07-22)Psychological attachment to an entrepreneurial opportunity may motivate the entrepreneur to persevere but can also bias decisions made in the entrepreneurial process, especially on market entry. This thesis investigates ... -
The Role of Apoptosis Repressor with Caspase Recruitment Domain in Aging Mouse Skeletal Muscle Morphology and Apoptotic Signaling
(University of Waterloo, 2015-01-23)Abstract Aging is associated with a loss of skeletal muscle mass, known as sarcopenia, which results in numerous degenerative alterations and decreased strength. One of the major mechanisms influencing muscle wasting in ... -
Role of Artificial Intelligence in Theranostics: Toward Routine Personalized Radiopharmaceutical Therapies
(Elsevier, 2021-10)KEY POINTS AI has shown promising applications in quantitative imaging required for dosimetry. Segmentation of organs and tumors, the most time consuming task in the dosimetry workflow, can be automated using AI. ... -
The Role of Binocular Vision during the Performance of Complex Manipulation Skills
(University of Waterloo, 2015-09-14)The overall goal for this thesis was to examine the significance of binocular vision during the performance of complex manipulation tasks in visually-normal children and adults. The goal of study 1 was to examine the ... -
