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
(University of Waterloo, 2021-07-22)Interlocking Concrete pavers (ICPs) have become increasingly common in North America. These pavements consist of impermeable concrete paving units and permeable joints that allow water to freely enter the surface. The ... -
Human motion estimation and controller learning
(University of Waterloo, 2021-07-22)Humans are capable of complex manipulation and locomotion tasks. They are able to achieve energy-efficient gait, reject disturbances, handle changing loads, and adapt to environmental constraints. Using inspiration from ... -
Accounting Conservatism and Risk Disclosures
(University of Waterloo, 2021-07-22)This thesis adopts a broad view of conservative financial reporting—managers can use two ways to communicate business uncertainties to outsiders, namely, conservative accounting via timely loss recognition and narrative ... -
Ecological legacies of long-term plant management along the Central Coast of British Columbia
(University of Waterloo, 2021-07-22)Quantifying long-term human impacts to landscapes allows us to understand the ways in which ecosystems respond to constant human pressure and the effects this pressure has on permanently influencing ecological processes ... -
Understanding Minimax Optimization in Modern Machine Learning
(University of Waterloo, 2021-07-21)Recent years has seen a surge of interest in building learning machines through adversarial training. One type of adversarial training is through a discriminator or an auxiliary classifier, such as Generative Adversarial ... -
Social Equity Dimensions of Flood Risk Management in Canada
(University of Waterloo, 2021-07-21)Disproportionate exposure to hazards among socioeconomically disadvantaged populations and racial/ethnic minority communities contributes to rising environmental injustices worldwide. Examining the link between race/ethnicity, ... -
Predictors of Palliative Home Care Costs in Ontario, Canada
(University of Waterloo, 2021-07-21)Background: The demand for palliative care in Canada is expected to grow in coming years due to a confluence of factors that include population aging, a more gradual dying process, emphasis on the early provision of ... -
Induced Binary Submatroids
(University of Waterloo, 2021-07-21)The notion of induced subgraphs is extensively studied in graph theory. An example is the famous Gy\'{a}rf\'{a}s-Sumner conjecture, which asserts that given a tree $T$ and a clique $K$, there exists a constant $c$ such ... -
Identifying regions of trusted prediction
(University of Waterloo, 2021-07-20)Quantifying the probability of a label prediction being correct on a given test point or a given sub-population enables users to better decide how to use and when to trust machine learning derived predictors. In this work, ... -
Design of Improved Carbon Capture Solvents Using Molecular Simulation
(University of Waterloo, 2021-07-20)Study of the equilibrium compositions of complex chemically reacting systems by means of experimental measurements and thermodynamic modeling tools is of great interest and importance in chemistry, biology, and chemical ... -
Merlynne: Motivating Peer-to-Peer Cognitive Behavioral Therapy with a Serious Game
(ACM, 2021-09)Human-Computer Interaction researchers have explored how online communities can be leveraged for peer support, but general disinterest and a lack of engagement have emerged as substantial barriers to their use in practice. ... -
Nature vs. Stress: Investigating the Use of Biophilia in Non-Violent Exploration Games to Reduce Stress
(ACM, 2021)Games hold the potential to help many address health-related issues such as chronic stress. We investigated the use of biophilia, an affective response to nature grounded in the psychology literature, as indirect physiological ... -
Circuit Complexity of Mixed States
(University of Waterloo, 2021-07-20)Quantum information has produced fresh insights into foundational questions about the AdS/CFT correspondence. One fascinating concept, which has captured increasing attention, is quantum circuit complexity. As a natural ... -
Neural control of the healthy pectoralis major from low-to-moderate isometric contractions
(American Physiological Society, 2021-07-01)The pectoralis major critically enables arm movement in several directions. However, its neural control remains unknown. High-density electromyography (HD-sEMG) was acquired from the pectoralis major in two sets of experiments ... -
Velocity scaling of high-speed turbulent boundary layer flows with wall heat transfer
(University of Waterloo, 2021-07-19)The law of the wall has been a staple in collapsing the mean velocity profiles of seemingly very different turbulent channel and boundary layer flows into one single, semi-analytical function. Accordingly, it has equipped ... -
Adaptive Control of a First-Order System Providing Linear-Like Behaviour and Asymptotic Tracking
(University of Waterloo, 2021-07-19)Adaptive control is an approach used to deal with systems having uncertain and/or time-varying parameters. In this thesis, we consider the problem of designing an adaptive controller for a discrete-time first-order plant. ... -
Analysis of Stochastic Models through Multi-Layer Markov Modulated Fluid Flow Processes
(University of Waterloo, 2021-07-19)This thesis is concerned with the multi-layer Markov modulated fluid flow (MMFF) processes and their applications to queueing systems with customer abandonment. For the multi-layer MMFF processes, we review and refine ...
