Dynamic Treatment Regimes with Interference
(University of Waterloo, 2022-08-18)Precision medicine describes healthcare in which patient-level data are used to inform treatment decisions. Within this framework, dynamic treatment regimes (DTRs) are sequences of decision rules that take individual patient ... -
A Dynamic User-Centric Mobile Context Model
(University of Waterloo, 2010-07-22)Context-aware systems can dynamically adapt to user situations to provide smarter services. In general, context refers to the information that can be used to characterize these situations, and context models are deployed ... -
Dynamic-Occlusion-Aware Risk Identification for Autonomous Vehicles Using Hypergames
(University of Waterloo, 2021-12-17)A particular challenge for both autonomous vehicles (AV) and human drivers is dealing with risk associated with dynamic occlusion, i.e., occlusion caused by other vehicles in traffic. In order to overcome this challenge, ... -
Dynamical Systems in Spiking Neuromorphic Hardware
(University of Waterloo, 2019-05-10)Dynamical systems are universal computers. They can perceive stimuli, remember, learn from feedback, plan sequences of actions, and coordinate complex behavioural responses. The Neural Engineering Framework (NEF) provides ... -
Dynamical Systems Methods Applied to the Michaelis-Menten and Lindemann Mechanisms
(University of Waterloo, 2009-08-06)In the first part of this thesis, we will explore an iterative procedure to determine the detailed asymptotic behaviour of solutions of a certain class of nonlinear vector differential equations which approach a nonlinear ... -
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 ...
