Epidemic Models with Pulse Vaccination and Time Delay
(University of Waterloo, 2011-08-22)In this thesis we discuss deterministic compartmental epidemic models. We study the asymp- totic stability of the disease-free solution of models with pulse vaccination campaigns. The main contributions of this thesis ... -
An Epidemiological Analysis of Smoking and Smoking Cessation among Persons Undergoing Inpatient Treatment for Psychiatric Illness
(University of Waterloo, 2008-01-14)Background: Tobacco use increases the odds of suffering and dying prematurely from a host of chronic disease, including heart disease, stroke, cancer, lung diseases, and mental illness. There is limited published data ... -
The epidemiology and healthcare costs of pregnancy-related listeriosis in British Columbia, Canada, 2005-2014
(University of Waterloo, 2023-08-29)Introduction: Listeriosis, a disease caused by the bacteria Listeria monocytogenes, remains relatively rare in Canada. However, the case-fatality rate from listeriosis is high at 20-30%. Listeriosis in pregnancy is of ... -
The Epidemiology of Acute Gastrointestinal Illness in Ethiopia, Mozambique, Nigeria, and Tanzania
(University of Waterloo, 2022-04-26)Gastrointestinal infections transmitted by food are a global concern and most severe in African low-and-middle-income countries (LMICs), though in these countries accurate data on acute gastrointestinal illness (AGI) are ... -
The Episodic Nature of "Blessedness" in Spinoza's Ethics
(University of Waterloo, 2008-09-26)The final chapter of Spinoza’s Ethics has elicited numerous interpretations, and in this work, I discuss Jonathan Bennett’s and Harry Wolfson’s. Bennett claims that the doctrine of blessedness is unintelligible, while ... -
Epoxy Adhesives, Correlation between Strain Whitening and Damage Using a Macroscopic Optical Method
(University of Waterloo, 2019-03-12)The success of lightweight automotive multi-material assemblies depends on selecting appropriate joining techniques that can provide the expected day-to-day operational strength while delivering occupant protection during ... -
Equality of Number-Theoretic Functions over Consecutive Integers
(University of Waterloo, 2009-04-30)This thesis will survey a group of problems related to certain number-theoretic functions. In particular, for said functions, these problems take the form of when and how often they are equal over consecutive integers, n ... -
Equality Operators for Constant-weight Codewords with Applications in (Keyword) PIR
(University of Waterloo, 2021-09-21)Homomorphic encryption allows computation to be performed on data while in encrypted form. However, the computational overhead of a circuit that is run using homomorphic encryption depends on the number of multiplications ... -
Equator Principles and Climate Change Issues: Examining the EPs’ Climate Change Policies and Analyzing the Likely Effectiveness of these Policies
(University of Waterloo, 2016-04-07)Climate change is a global environmental issue that adversely affects economic activities; on the other hand, economic activities, in particular infrastructure project financing, are one of the main drivers of current ... -
Equiangular Lines and Antipodal Covers
(University of Waterloo, 2010-09-22)It is not hard to see that the number of equiangular lines in a complex space of dimension $d$ is at most $d^{2}$. A set of $d^{2}$ equiangular lines in a $d$-dimensional complex space is of significant importance in Quantum ... -
Equilibrium and dynamical computation schemes for vibronic models of nonadiabatic systems
(University of Waterloo, 2023-01-06)Two computational schemes were investigated for studying vibronic models of nonadiabatic systems: Path Integral Monte Carlo (PIMC) and vibrational electronic coupled cluster (VECC). A PIMC method was used to investigate ... -
Equilibrium and kinetic folding studies of two YchN-like proteins: the Tm0979 dimer and the Mth1491 trimer
(University of Waterloo, 2007-09-28)Proper folding of a protein to its native state is critical for the protein to be fully functional under biological conditions. Understanding protein folding and protein folding evolution within the same structural family ... -
Equilibrium Phase Behaviour of Liquid Crystalline Polymer Brushes
(University of Waterloo, 2019-08-29)Using self-consistent field theory of worm-like chains with Maier-Saupe interactions we study the equilibrium phase behaviour of liquid crystalline (LC) polymer brushes. In a good solvent the brush extends out normal to ... -
Equity Implications of Cordon Pricing in Downtown Toronto
(University of Waterloo, 2013-01-15)The City of Toronto has done much to reduce congestion through transportation system management and travel demand measures. Yet, while measures to eliminate the traffic congestion problem have been necessary, they simply ... -
Equivalence of Queries with Nested Aggregation
(University of Waterloo, 2009-12-11)Query equivalence is a fundamental problem within database theory. The correctness of all forms of logical query rewriting—join minimization, view flattening, rewriting over materialized views, various semantic optimizations ... -
The Erdős Pentagon Problem
(University of Waterloo, 2018-12-20)The Erdős pentagon problem asks about the maximum number of copies of C_5 that one can find in a triangle-free graph. This problem was posed in 1984, but was not resolved until 2012. In this thesis, we aim to capture the ... -
Erosion, Self-Organization, and Procedural Modeling
(University of Waterloo, 2015-01-16)Procedural modeling of natural objects such as coastlines and terrains in combination with their characteristic erosion features involves integration of appropriate physical models with the procedural approach and culminates ... -
Erosion: Desiging with Materiality in Impermanent Landscapes
(University of Waterloo, 2017-01-17)sing the Buddhist notion that we conceive of time through observing change, this thesis attempts to answer the question ‘how can we create the sensation of time in architecture?’ It is important to acknowledge the fact ... -
Error Bounds and Singularity Degree in Semidefinite Programming
(University of Waterloo, 2020-01-24)An important process in optimization is to determine the quality of a proposed solution. This usually entails calculation of the distance of a proposed solution to the optimal set and is referred to as forward error. ... -
Error characterization and quantum control benchmarking in liquid state NMR using quantum information processing techniques
(University of Waterloo, 2008-09-12)Quantum information processing has been the subject of countless discoveries since the early 1990's. It is believed to be the way of the future for computation: using quantum systems permits one to perform computation ...
