Pragmatic Groundwater-Surface Water Model Coupling with Unstructured Grids
(University of Waterloo, 2021-07-29)Faced with an array of water issues exacerbated by a rapidly changing climate, hydrologists and hydrogeologists have increasingly found themselves needing to simultaneously model the groundwater and surface water domains ... -
Defects and Boundaries in Quantum Field Theories
(University of Waterloo, 2021-07-29)We discuss some aspects of defects and boundaries in quantum field theories (QFTs) and their applications in revealing non-perturbative aspects of QFTs in combination with other techniques, including integrability. ... -
Quantum Blind Data Compression and Structure of Quantum Operations Approximately Preserving Quantum States
(University of Waterloo, 2021-07-29)In this thesis, we investigate a variation of quantum information processing tasks, blind data compression, and we analyze an approximation of a structure of a set of quantum states closely related to the task, which is ... -
Exploring, Understanding, and Determining the Quality of Plan Monitoring and Evaluation in Ontario
(University of Waterloo, 2021-07-28)Planning takes place in the context of diverse stakeholder interests and complex decision-making processes. Planning activities are often complicated by a range of factors: increasing pressure on municipalities with ageing ... -
High Areal-capacity and Durable Aqueous Rechargeable Zinc Li-ion Battery
(University of Waterloo, 2021-07-28)Rapid deployment of renewable energy sources around the world is crucial to lessen energy shortage and environmental pollution. As the contribution of renewable energy rises, energy storage with different battery systems ... -
Investigating the Commitment to Official Plan Monitoring and Evaluation in Ontario’s Mid-Sized Cities
(University of Waterloo, 2021-07-28)Plans often need updates to stay applicable to evolving needs, experiences and knowledge. In this context, monitoring and evaluation of plans has a critical role to play in guaranteeing the applicability and relevance of ... -
Failure Time Analysis with Discrete Marker Processes under Intermittent Observation
(University of Waterloo, 2021-07-28)Regression analysis for failure time data is often directed at studying the relationship between a time-dependent biomarker and failure. The Cox regression model and the associated partial likelihood on which inference ... -
Essays on building and evaluating two-stage DEA models of efficiency and effectiveness
(University of Waterloo, 2021-07-27)Researchers are not consistent in their choice of input and output variables when using two-stage data envelopment analysis (DEA) models to measure efficiency and effectiveness. This inconsistency has resulted in the ... -
Plastic Film and Packaging Waste Management in Southwestern Ontario: An analysis of current diversion patterns and trends
(University of Waterloo, 2021-07-27)The production of plastics has drastically grown through the years. In the age of convenience, single use plastics (especially film) have become ubiquitous in everyday life and so has its waste. Plastic waste can be found ... -
Topics in Study Design and Analysis Involving Incomplete Data
(University of Waterloo, 2021-07-27)Incomplete data is a common occurrence in statistics with various types and mechanisms such that each can have a significant effect on statistical analysis and inference. This thesis tackles several statistical issues in ... -
Spatial analysis exploring the influence of stream daylighting in building resilient urban form: A study of Zürich, Switzerland’s ‘Bachkonzept’ for stream daylighting
(University of Waterloo, 2021-07-27)Cities face several risks that jeopardize their adaptability as the effects of climate change and urbanization on our ecosystems intensify. Recognizing the potentially disastrous outcomes of inaction, local governments and ... -
Deep Learning Tools for Yield and Price Forecasting Using Satellite Images
(University of Waterloo, 2021-07-26)The ability to forecast crop yields and prices is vital to secure global food availability and provide farmers, retailers, and consumers with valuable information to maximize effectiveness. Conventional approaches used to ... -
Impact of Anaerobic Biofilm Formation on Sorption Characteristics of Powdered Activated Carbon
(University of Waterloo, 2021-07-23)Subsurface contamination by petroleum hydrocarbons (PHCs) results from the leakage of petroleum products during extraction, processing or transport. It has been documented that activated carbon (AC) can effectively sorb ... -
A Class of Augmented Convolutional Networks Architectures for Efficient Visual Anomaly Detection
(University of Waterloo, 2021-07-23)Visual anomaly detection, the task of isolating visual data that do not conform to the defined notion of normality, is very crucial for the autonomous functioning of entities with exceptional potential in a spectrum of ... -
AI Aided Tools for Fresh Produce Yield and Price Forecasting: Deep Learning Approaches
(University of Waterloo, 2021-07-22)It is important to have an accurate estimate of the yields and prices of fresh produce (FP) for maintaining an effective Fresh Produce Supply Chain Management (FSCM). Since, the FP comprises of the perishable goods, it is ... -
Development of a New and Innovative Concrete Paver
