Strategic Interactions in Antiviral Drug Use During an Influenza Pandemic
(Public Library of Science, 2017-01-12)Background: The evolution of antiviral drug resistance during influenza pandemics has created widespread concern. Use of antiviral drugs is a main contributor to the evolution of drug-resistant strains. Moreover, there are ... -
Strategic Voting and Social Networks
(University of Waterloo, 2018-01-19)With the ever increasing ubiquity of social networks in our everyday lives, comes an increasing urgency for us to understand their impact on human behavior. Social networks quantify the ways in which we communicate with ... -
Stratified Flow Over Topography: Steady Nonlinear Waves, Boundary Layer Instabilities, and Crater Topography
(University of Waterloo, 2013-11-29)This thesis investigates several aspects of stratified flow over isolated topography in ocean, lake, and atmospheric settings. Three major sub-topics are addressed: steady, inviscid internal waves trapped over topography ... -
Stream WatDiv - A Streaming RDF Benchmark
(University of Waterloo, 2018-01-18)Modern applications are required to process stream data which are semantically tagged. Sometimes static background data interlinked with stream data are also needed to answer the query. To meet these requirements, streaming ... -
Streaming and Dynamic Algorithms for Minimum Enclosing Balls in High Dimensions
(University of Waterloo, 2011-08-30)At SODA'10, Agarwal and Sharathkumar presented a streaming algorithm for approximating the minimum enclosing ball of a set of points in d-dimensional Euclidean space. Their algorithm requires one pass, uses O(d) space, ... -
Strong Morita Equivalence and Imprimitivity Theorems
(University of Waterloo, 2016-09-15)The purpose of this thesis is to give an exposition of two topics, mostly following the books \cite{R & W} and \cite{Wil}. First, we wish to investigate crossed product $C^*$-algebras in its most general form. Crossed ... -
A Structural Modelling Approach to Closed End Bond Funds
(University of Waterloo, 2013-08-28)This thesis develops a model of closed end bond funds that helps us better understand a recent finding in the literature. In 2012 Elton et al. published an empirical study of closed end bond funds (CEBFs) and they suggested ... -
Structure in Stable Matching Problems
(University of Waterloo, 2016-12-14)In this thesis we provide two contributions to the study of structure in stable matching problems. The first contribution is a short new proof for the integrality of Rothblum’s linear description of the convex hull of ... -
Structured Mixture Models
(University of Waterloo, 2023-08-11)Finite mixture models are a staple of model-based clustering approaches for distinguishing subgroups. A common mixture model is the finite Gaussian mixture model, whose degrees of freedom scales quadratically with increasing ... -
Structured Prediction on Dirty Datasets
(University of Waterloo, 2021-12-20)Many errors cannot be detected or repaired without taking into account the underlying structure and dependencies in the dataset. One way of modeling the structure of the data is graphical models. Graphical models combine ... -
Structured Reverse Mode Automatic Differentiation in Nested Monte Carlo Simulations
(University of Waterloo, 2017-01-17)In many practical large scale computational problems, the calculation of partial derivatives of the object function f with respect to input parameters are entailed and the dimension of inputs n is much larger the one of ... -
Structured Total Least Squares for Approximate Polynomial Operations
(University of Waterloo, 2004)This thesis presents techniques for accurately computing a number of fundamental operations on approximate polynomials. The general goal is to determine nearby polynomials which have a non-trivial result for the operation. ... -
Struts2JSF: Framework Migration in J2EE Using Framework Specific Modeling Languages
(University of Waterloo, 2007-05-16)Java 2 Enterprise Edition is a portable, robust, scalable and secure platform for enterprise software development based on Java technologies, and embraces open standards through the Java Community Process (JCP). J2EE ... -
Student Success in Co-operative Education: An Analysis of Job Postings and Performance Evaluations
(University of Waterloo, 2023-05-26)Co-operative education (co-op) programs combine coursework and work internships and have become popular worldwide. In this analysis, we use two separate co-op datasets to understand employer expectations and factors that ... -
Studies of tumor heterogeneity, tumor microenvironment, and radiotherapy: A mathematical and computational approach
(University of Waterloo, 2019-01-04)Radiotherapy uses high doses of energy to eradicate cancer cells and thus destroy the bulk of tumors. Radiobiologists try to precisely deliver radiation to a targeted area in order to maximize the cancer cell kill rate ... -
A Study in Preference Elicitation under Uncertainty
(University of Waterloo, 2011-08-30)In many areas of Artificial Intelligence (AI), we are interested in helping people make better decisions. This help can result in two advantages. First, computers can process large amounts of data and perform quick ... -
A Study of Adaptation Mechanisms for Simulation Algorithms
(University of Waterloo, 2012-08-30)The performance of a program can sometimes greatly improve if it was known in advance the features of the input the program is supposed to process, the actual operating parameters it is supposed to work with, or the ... -
A Study of Efficiency, Accuracy, and Robustness in Intensity-Based Rigid Image Registration
(University of Waterloo, 2008-09-30)Image registration is widely used in different areas nowadays. Usually, the efficiency, accuracy, and robustness in the registration process are concerned in applications. This thesis studies these issues by presenting an ... -
A Study of Immediate Requery Behavior in Search
(Association for Computing Machinery, 2018-03-11)When search results fail to satisfy users' information needs, users often reformulate their search query in the hopes of receiving better results. In many cases, users immediately requery without clicking on any search ... -
A Study of Infectious Disease Models with Switching
(University of Waterloo, 2009-05-20)Infectious disease models with switching are constructed and investigated in detail. Modelling infectious diseases as switched systems, which are systems that combine continuous dynamics with discrete logic, allows for the ...
