SEEDS: Secure Decentralized Storage for Authentication Material
(University of Waterloo, 2022-03-03)Applications that use passwords or cryptographic keys to authenticate users or perform cryptographic operations rely on centralized solutions. Trusted Platform Modules (TPMs) do not offer a way to replicate material, making ... -
Seeking Middle Ground: Reconciling two trajectories for food system relocalization
(University of Waterloo, 2018-09-25)As food systems expand in scale and scope, the sources of their negative externalities are less effectively identified. Globally, this diffusion has resulted in a plethora of paradoxes, as well as a decrease in overall ... -
Seeking Renewal: The Value of Nature and Pausing in Shifting our Focus Inward
(University of Waterloo, 2020-09-10)We live in a society that is overly fixated on our outer conditions and stimuli rather than our inner state, which is seen through one of the behaviours this outward focus produces, busyness. So often we choose filling ... -
Seeking Safety: The Perceived Function and Consequences of Safety Behaviour Use in Social Anxiety
(University of Waterloo, 2017-08-29)This study was designed to examine the perceived self-protective function and consequences of safety behaviour use in social anxiety. The research explores how individuals’ selection and use of different types of safety ... -
Seeking Structure in Social Organization: Compensatory Control and the Psychological Advantages of Hierarchy
(University of Waterloo, 2013-09-23)Hierarchies are a ubiquitous form of human social organization. I hypothesized that one reason for hierarchies’ prevalence might be that core motivational needs for order and control make hierarchies psychologically ... -
Seeking the Source: Dioxin Exposure Levels and Determinants and Fluoroalkyl Substance Determinants in Arctic and Subarctic Communities within Canada
(University of Waterloo, 2023-11-27)Abstract Background Dioxins, furans, and non-ortho dioxin-like polychlorinated biphenyls (PCBs), and per- and poly- fluoroalkyls (PFAS) are persistent toxic chemicals that have been detected in areas far from known ... -
SEGMENTATION INFORMS THE GAMIFICATION OF SUSTAINABLE FOOD CONSUMPTION
(University of Waterloo, 2024-01-18)Food systems activities produce around 30% of global anthropogenic greenhouse gas (GHG) emissions and are responsible for numerous environmental issues which could ultimately harm our ability to grow food reliably. One way ... -
Segmentation of 3D Carotid Ultrasound Images Using Weak Geometric Priors
(University of Waterloo, 2010-10-29)Vascular diseases are among the leading causes of death in Canada and around the globe. A major underlying cause of most such medical conditions is atherosclerosis, a gradual accumulation of plaque on the walls of blood ... -
Segmentation of RADARSAT-2 Dual-Polarization Sea Ice Imagery
(University of Waterloo, 2009-09-24)The mapping of sea ice is an important task for understanding global climate and for safe shipping. Currently, sea ice maps are created by human analysts with the help of remote sensing imagery, including synthetic aperture ... -
Seismic Coupling and Hydrological Responses
(University of Waterloo, 2006)In seismology, the capability of an earthquake to induce other seismic events has been widely accepted for decades. For example, the term aftershock involves a strong relation of such a seismic event with the incidence ... -
Seismic Fragility Analysis for Structures, Systems, and Components in Nuclear Power Plants
(University of Waterloo, 2017-01-18)Seismic fragility analysis has been widely used to evaluate seismic capacities of structures, systems, and components (SSCs) in nuclear power plants. In the seismic fragility analysis, a single ground motion parameter ... -
Seismic Performance Assessment of Multi-Storey Buildings with Cold Formed Steel Shear Wall Systems
(University of Waterloo, 2007-05-22)Cold-Formed Steel (CFS) is a material used in the fabrication of structural and non-structural elements for the construction of commercial and residential buildings. CFS exhibits several advantages over other construction ... -
Seismic Risk Analysis for Nuclear Energy Facilities
(University of Waterloo, 2015-02-20)Earthquakes are destructive natural disasters that can inflict various levels of damage on engineering structures and lead to other adverse consequences. Accurate seismic risk quantification of critical engineering structures ... -
Selectable Heaps and Their Application to Lazy Search Trees
(University of Waterloo, 2021-04-29)We show the O(log n) time extract minimum function of efficient priority queues can be generalized to the extraction of the k smallest elements in O(k log(n/k)) time. We first show the heap-ordered tree selection of Kaplan ... -
Selected Experiments with Proteins at Solid-Liquid Interfaces
(University of Waterloo, 2008-12-12)This thesis describes a number of novel experiments contributing to the understanding of protein adsorption from both a fundamental and applied perspective. The first three papers involve the use of the localized surface ... -
Selected topics in Computational Relativity
(University of Waterloo, 2022-08-18)This thesis addresses a collection of topics that are either directly related to, or have implications for, current challenges in computational relativity. In the first part, we explore a spacetime discretization method ... -
Selected Topics in Variable Annuities
(University of Waterloo, 2021-06-22)Variable annuities are long-term insurance products. They have become one of the most popular savings/investment vehicles over the past two decades due to their flexible investment options, stable long-term guarantees, and ... -
Selecting Sustainable Point-of-Use and Point-of-Entry Drinking Water Treatment: A Decision Support System
(University of Waterloo, 2011-08-10)Point-of-use (POU) and point-of-entry (POE) water treatment are forms of decentralized water treatment that are becoming increasingly sought alternatives for ensuring the safety of drinking water. Although the acceptance ... -
Selection and characterization of an aptamer to a thiazole orange derivative for use in a fluorescence-based biosensor
(University of Waterloo, 2023-08-18)Aptamers are short single-stranded DNA or RNA sequences that have been selected in vitro to have a high binding affinity to a specific target molecule. One class of aptamers can bind to small non-fluorescent molecules to ... -
Selective Flooding in Ad Hoc Networks
(University of Waterloo, 2002)An ad hoc network is a collection of mobile wireless devices that cooperate with each other to route packets amongst themselves. The main difficulty in designing routing algorithms for such a network is the large number ...
