Dynamics And Control Of Foot-And-Mouth Disease In Endemic Countries: A Pair Approximation Model
(Elsevier, 2014-09-21)Previous mathematical models of spatial farm-to-farm transmission of foot and mouth disease (FMD) have explored the impacts of control measures such as culling and vaccination during a single outbreak in a country normally ... -
Dynamics of a Diffusive Nutrient-Phytoplankton-Zooplankton Model with Spatio-temporal Delay
(SIAM, 2021-01)We study a diffusive nutrient-phytoplankton-zooplankton (NPZ) model with spatio-temporal delay. The closed nature of the system allows the formulation of a conservation law of biomass that governs the ecosystem. We advance ... -
The Dynamics of Inhomogeneous Cosmologies
(University of Waterloo, 2004)In this thesis we investigate cosmological models more general than the isotropic and homogeneous Friedmann-Lemaître models. We focus on cosmologies with one spatial degree of freedom, whose matter content ... -
The Dynamics of the Beaufort Gyre
(University of Waterloo, 2020-09-23)The Beaufort gyre is located in the Canadian Arctic basin and is responsible for the dominant circulation of the Beaufort Sea. Currently, the gyre flows in an anti-cyclonic direction, which leads to the deflection of fresh ... -
Dynamics Of The Global Wheat Trade Network And Resilience To Shocks
(Nature Publishing Group, 2017-08-03)Agri-food trade networks are increasingly vital to human well-being in a globalising world. Models can help us gain insights into trade network dynamics and predict how they might respond to future disturbances such as ... -
Dynamics of the spherical Sherrington-Kirkpatrick model and average case complexity for top eigenvectors
(University of Waterloo, 2023-04-28)In this Master’s thesis, we investigate the Langevin dynamics on the spherical Sherrington- Kirkpatrick (SSK) model, a classical mean-field spin glass model. The first contribution of this thesis is the asymptotic limit ... -
Early Language Learning is a Good Model for Studying Early User Interface Learning
(University of Waterloo, 2005)To date, the self-revealing interface has been the elusive holy grail of the user interface community. This research advocates the use of early language learning as a model for early user interface learning. This model ... -
The Early Universe: New Aspects of Cuscuton Theory, Modified Dispersion Relations and Pulsar Constraints on Vacuum Noise
(University of Waterloo, 2017-10-26)The modern cosmology started blossoming in the early 1900s, with the theoretical framework provided by Einstein's general relativity. Soon after that, with observational discoveries such as expansion of cosmos by Hubble ... -
Early Warning Signals of Vaccine Scares.
(University of Waterloo, 2016-09-26)There exists strong evidence that vaccines are extremely effective in the prevention of pediatric infectious disease, yet despite this evidence, vaccine refusal is still popular amongst some parents. Existing mathematical ... -
The Eberlein Compactification of Locally Compact Groups
(University of Waterloo, 2013-01-24)A compact semigroup is, roughly, a semigroup compactification of a locally compact group if it contains a dense homomorphic image of the group. The theory of semigroup compactifications has been developed in connection ... -
Economic Pricing of Mortality-Linked Securities
(University of Waterloo, 2012-09-26)In previous research on pricing mortality-linked securities, the no-arbitrage approach is often used. However, this method, which takes market prices as given, is difficult to implement in today's embryonic market where ... -
Edge coloring multigraphs without small dense subsets
(Elsevier, 2015-12-06)One consequence of a long-standing conjecture of Goldberg and Seymour about the chromatic index of multigraphs would be the following statement. Suppose $G$ is a multigraph with maximum degree $\Delta$, such that no vertex ... -
Edge Estimation and Community Detection in Time-varying Networks
(University of Waterloo, 2024-04-30)In modern statistics and data science, there is a growing focus on network data that indicate interactions among a group of items in a complex system. Scientists are interested in these data as they can reveal important ... -
Edge State Transfer
(University of Waterloo, 2019-01-11)Let G be a graph and let t be a positive real number. Then the evolution of the continuous quantum walk defined on G is described by the transition matrix U(t)=exp(itH).The matrix H is called Hamiltonian. So far the most ... -
Edge-disjoint Linkages in Infinite Graphs
(University of Waterloo, 2022-09-26)The main subject of this thesis is the infinite graph version of the weak linkage conjecture by Thomassen [24]. We first prove results about the structure of the lifting graph; Theorems 2.2.8, 2.2.24, and 2.3.1. As an ... -
EdgeX: Edge Replication for Web Applications
(University of Waterloo, 2015-10-13)Global web applications face the problem of high network latency due to their need to communicate with distant data centers. Many applications use edge networks for caching images, CSS, javascript, and other static content ... -
Editing Fluid Flows with Divergence-Free Biharmonic Vector Field Interpolation
(University of Waterloo, 2022-09-16)Achieving satisfying fluid animation through numerical simulation can be time-consuming because such simulations are computationally expensive to perform and there are few practical post-processing tools for editing of ... -
The Edmonds-Giles Conjecture and its Relaxations
(University of Waterloo, 2022-12-23)Given a directed graph, a directed cut is a cut with all arcs oriented in the same direction, and a directed join is a set of arcs which intersects every directed cut at least once. Edmonds and Giles conjectured for all ... -
Effcient Simulation of Message-Passing in Distributed-Memory Architectures
(University of Waterloo, 1996)In this thesis we propose a distributed-memory parallel-computer simulation system called PUPPET (Performance Under a Pseudo-Parallel EnvironmenT). It allows the evaluation of parallel programs run in a pseudo-parallel ... -
Effect of a Mobile Phone Intervention on Quitting Smoking in a Young Adult Population of Smokers: Randomized Controlled Trial
(JMIR, 2018-10-23)Background: Digital mobile technology presents a promising medium for reaching young adults with smoking cessation interventions because they are the heaviest users of this technology. Objective: The aim of this study ...
