On the Perpetuation of Ignorance: System Dependence, System Justification, and the Motivated Avoidance of Socio-Political Information
(University of Waterloo, 2012-06-28)How do people cope when they feel uninformed or unable to understand important social issues, such as the environment, energy concerns, or the economy? One would intuitively expect that a lack of knowledge would motivate ... -
On the planar flow development and structural loading of cylinders with circular fins in cross-flow
(University of Waterloo, 2015-05-14)Finned cylinders are commonly encountered in the design of heat exchangers. Critical to the design and performance of a heat exchanger are the mean and fluctuating loading on the tubes, as they relate to pressure losses ... -
On the Polyhedral Lift-and-Project Rank Conjecture for the Fractional Stable Set Polytope
(University of Waterloo, 2008-01-16)In this thesis, we study the behaviour of Lovasz and Schrijver's lift-and-project operators N and N_0 while being applied recursively to the fractional stable set polytope of a graph. We focus on two related conjectures ... -
On the Potential Use of Small Scale Fire Tests for Screening Steiner Tunnel Results for Spray Foam Insulation
(University of Waterloo, 2013-05-21)The goal of this study is to assess the potential of using bench-scale fire testing to screen materials for the Steiner tunnel fire test. It is hypothesized that the chemical and physical changes made to a material to ... -
On the Power and Limitations of Shallow Quantum Circuits
(University of Waterloo, 2022-09-01)Constant-depth quantum circuits, or shallow quantum circuits, have been shown to exhibit behavior that is uniquely quantum. This thesis explores the power and limitations of constant-depth quantum circuits, in particular ... -
On the power of interleaved low-depth quantum and classical circuits
(University of Waterloo, 2022-09-26)Low-depth quantum circuits are a well-suited model for near-term quantum devices, given short coherence times and noisy gate operations, making it pivotal to examine their computational power. It was already known as early ... -
On The Precipice Of Change
(University of Waterloo, 2014-09-18)Situated centrally, two blocks north of People’s Square, in Zhabei District of Shanghai, China, Sihang Warehouse is a place steeped in time. In 1937, during the Sino-Japanese War, when this building was still one of ... -
On the Prediction of Gas Hold-up in Ebullated Bed Reactors
(University of Waterloo, 2019-09-19)Commercial ebullated bed reactors (EBRs) are three-phase fluidized bed systems used for hydroprocessing (upgrading) of bitumen, a major Canadian resource. The objective of this thesis is to improve the understanding of the ... -
On the Properties and Structure of Bordered Words and Generalizations
(University of Waterloo, 2022-10-12)Combinatorics on words is a field of mathematics and theoretical computer science that is concerned with sequences of symbols called words, or strings. One class of words that are ubiquitous in combinatorics on words, ... -
On the Relation between Quantum Discord and Purified Entanglement
(University of Waterloo, 2013-08-30)In this thesis, I study bipartite discord between A and B in terms of the structure formed by the bipartite and tripartite entanglement found in the purified system ABC. I find that discord manifests itself only when there ... -
On the Relationship between Conjugate Gradient and Optimal First-Order Methods for Convex Optimization
(University of Waterloo, 2014-01-23)In a series of work initiated by Nemirovsky and Yudin, and later extended by Nesterov, first-order algorithms for unconstrained minimization with optimal theoretical complexity bound have been proposed. On the other hand, ... -
On the relationship between satisfiability and partially observable Markov decision processes
(University of Waterloo, 2018-09-26)Stochastic satisfiability (SSAT), Quantified Boolean Satisfiability (QBF) and decision-theoretic planning in finite horizon partially observable Markov decision processes (POMDPs) are all PSPACE-Complete problems. Since ... -
On the Relationship between Sum-Product Networks and Bayesian Networks
(University of Waterloo, 2015-06-08)Sum-Product Networks (SPNs), which are probabilistic inference machines, have attracted a lot of interests in recent years. They have a wide range of applications, including but not limited to activity modeling, language ... -
On the Relationship Between the Developer’s Perceptible Ethnicity and the Evaluation of Contributions in GitHub
(University of Waterloo, 2020-08-28)Context: Open Source Software (OSS) projects are typically the result of collective efforts performed by developers with different backgrounds. Although the quality of developers' contributions should be the only factor ... -
On the Relationships Between Mind-Wandering, ADHD, Engagingness, and Effort
(University of Waterloo, 2020-12-21)Existing research on mind-wandering (MW) has found that adults with attention-deficit hyperactivity disorder (ADHD) experience it more frequently and find it more disruptive to their daily lives than individuals without ... -
On the Representation Theory of Semisimple Lie Groups
(University of Waterloo, 2010-08-30)This thesis is an expository account of three central theorems in the representation theory of semisimple Lie groups, namely the theorems of Borel-Weil-Bott, Casselman-Osborne and Kostant. The first of these realizes all ... -
On the Response of 7000-Series Alloys to Hot Stamping
(University of Waterloo, 2020-01-07)Hot stamping, or die quenching (DQ), of 7000-series aluminum alloys is a metal forming process in which a blank is heated (solutionized) and then quenched and formed in cold tooling. The formed part is then subjected ... -
On the Road to Making Science of “Art”: Risk Bias in Market Scoring Rules
(The Institute for Operations Research and the Management Sciences, 2018-06)We study market scoring rule (MSR) prediction markets in the presence of risk-averse or risk-seeking agents that have unknown yet bounded risk preferences. It is well known that if agents can be prescreened, then MSRs can ... -
