At the Corner of Space and Time
(University of Waterloo, 2019-12-09)We perform a rigorous piecewise-flat discretization of classical general relativity in the first-order formulation, in both 2+1 and 3+1 dimensions, carefully keeping track of curvature and torsion via holonomies. We show ... -
Bedload sediment transport regimes of urban gravel-bed rivers under different management scenarios
(University of Waterloo, 2019-12-09)Watershed urbanization profoundly alters the hydrologic characteristics of urban rivers compared to their rural counterparts. This change in hydrologic conditions in combination with alterations to the sediment supply ... -
Communal Inferentialism: Charles S. Peirce’s Critique of Epistemic Individualism
(University of Waterloo, 2019-12-09)Charles S. Peirce’s critique of epistemic individualism, the attempt to make the individual the locus of knowledge, is a dominant theme in his writings. While scholars often mention this critique, there is, surprisingly, ... -
Novel Starch Nanocomposites
(University of Waterloo, 2019-12-09)Thermoplastic materials using bio-derived renewable resources are studied intensively and are widely used in applications including packaging, agriculture and other consumer goods. Starch-based plastics exhibit a good ... -
Computationally Efficient Field-Theoretic Simulations for Block Copolymer Melts
(American Chemical Society, 2019-11-12)Field-theoretic simulations (FTS) provide fluctuation corrections to self-consistent field theory (SCFT) by simulating its field-theoretic Hamiltonian rather than applying the saddle-point approximation. Although FTS work ... -
Thin film composite membranes via layer-by-layer assembly for pervaporation separation
(University of Waterloo, 2019-12-06)The aim of this study was to develop LbL membranes based on polyethyleneimine and graphene oxide (PEI/GO) and to investigate them for three different applications, namely the pervaporative desalination of high-salinity ... -
Design and Evaluation of Grasp Assistive Devices in an Industrial Environment
(University of Waterloo, 2019-12-06)Carpal tunnel syndrome and tendonitis are two common upper extremity cumulative trauma disorders related to repetitive and forceful activities in the workplace. The objective of this research was to reduce the hand force ... -
Coordinated Voltage and Reactive Power Control for Renewable Dominant Smart Distribution Systems
(University of Waterloo, 2019-12-06)Driven by their economic and environmental advantages, smart grids promote the deployment of active components, including renewable energy sources (RESs), energy storage systems (ESSs), and electric vehicles (EVs), for ... -
Enabling the Integration of Ecosystem Service-based Approaches into Planning Organizations: Municipal Natural Asset Management
(University of Waterloo, 2019-12-06)This research seeks to help bridge the gap between science and practice around the integration of ecosystem service-based approaches within municipal planning. This thesis identified enablers of organizational change needed ... -
A Canadian Study of Young Adults’ Suburban Ways of Living
(University of Waterloo, 2019-12-06)This thesis contributes to a better understanding of how young adults are living, in regard to the suburban and urban nature of their lifestyles. Specifically, it explores young adults’ ways of living in Canada and are ... -
Application of a Hydrological Model for Predicting River Ice Breakup
(University of Waterloo, 2019-12-06)In cold regions, the breakup of river ice can be a significant event, resulting in flooding and damage to communities. Given the severity of such events, it is desirable to be able to predict the timing and severity of ... -
Design and Implementation of Google Cloud Framework for Monitoring Water Distribution Networks
(University of Waterloo, 2019-12-06)With urbanization and growing human population, water demand is constantly on the rise. Due to limited water resources, providing access to fresh potable water to the rising needs is challenging. Water distribution systems ... -
In-situ chemical oxidation of chlorendic acid by persulfate: Elucidation of the roles of adsorption and oxidation on chlorendic acid removal
(Elsevier, 2019-10-15)The oxidation of chlorendic acid (CA), a polychlorinated recalcitrant contaminant, by heat-, mineral-, and base-activated persulfate was investigated. In pH 3–12 homogeneous (i.e., solid-free) solutions, CA was oxidized ... -
Reduction of chlorendic acid by zero-valent iron: Kinetics, products, and pathways
(Elsevier, 2020-02-15)Chlorendic acid (CA) is a recalcitrant groundwater contaminant for which an effective treatment technology does not currently exist. In this study, a series of batch experiments were conducted to investigate the treatment ... -
The Effect of Religious Participation on Cognitive Function in Middle- and Old-Aged Adults: A Sequential Explanatory Mixed Methods Study of the Canadian Longitudinal Study on Aging
(University of Waterloo, 2019-12-05)Background: Preserving cognitive health is a crucial aspect of successful aging. Atypical cognitive decline is linked to the onset of dementia disorders such as Alzheimer’s disease. Even normal cognitive deterioration can ... -
Automatic Identification of Algae using Low-cost Multispectral Fluorescence Digital Microscopy, Hierarchical Classification & Deep Learning
(University of Waterloo, 2019-12-05)Harmful algae blooms (HABs) can produce lethal toxins and are a rising global concern. In response to this threat, many organizations are monitoring algae populations to determine if a water body might be contaminated. ... -
Effective removal of silica and sulfide from oil sands thermal in-situ produced water by electrocoagulation
(Elsevier, 2019-12-15)Effective removal of silica and sulfide from oil sands thermal in-situ produced water can reduce corrosion and scaling of steam generators, enhancing water recycling and reuse in the industry. The removal of these two ... -
From eye to face: The impact of face outline, feature number, and feature saliency on the early neural response to faces
(Elsevier, 2019-11-01)The LIFTED model of early face perception postulates that the face-sensitive N170 event-related potential may reflect underlying neural inhibition mechanisms which serve to regulate holistic and featural processing. It ... -
The semiconductor properties of passive films and corrosion behavior of stainless steel reinforcing bars in simulated concrete pore solution
(Elsevier, 2019-06)The vulnerability of concrete reinforcing steels to corrosion when depassivation occurs, typically in the presence of chloride, makes it important to understand the nature of the steels’ passive films. In Part I of the ... -
