How I wasted too long finding a concentration inequality for sums of geometric variables
(2011)I wanted a concentration inequality for sums of iid geometric random variables. This took way too long. 
How many crowdsourced workers should a requester hire?
(Springer, 201601)Recent years have seen an increased interest in crowdsourcing as a way of obtaining information from a potentially large group of workers at a reduced cost. The crowdsourcing process, as we consider in this paper, is as ... 
How Programmers Comment When They Think Nobody's Watching
(University of Waterloo, 20140417)Documentation is essential to software development. Experienced programmers know this well from having worked with poorly documented code. They wish to improve their documentation techniques and habits, but there is ... 
Hubble Spacer Telescope
(University of Waterloo, 20220119)Visualizing a model checker’s run on a model can be useful when trying to gain a deeper understanding of the verification of the particular model. However, it can be difficult to formalize the problem that visualization ... 
Human Skin Modelling and Rendering
(University of Waterloo, 2004)Creating realisticlooking skin is one of the holy grails of computer graphics and is still an active area of research. The problem is challenging due to the inherent complexity of skin and its variations, not only across ... 
HumanAI Interaction in the Presence of Ambiguity: From Deliberationbased Labeling to Ambiguityaware AI
(University of Waterloo, 20200911)Ambiguity, the quality of being open to more than one interpretation, permeates our lives. It comes in different forms including linguistic and visual ambiguity, arises for various reasons and gives rise to disagreements ... 
A HumanMachine Framework for the Classification of Phonocardiograms
(University of Waterloo, 20180420)In this thesis, we present and evaluate a framework for combining machine learning algo rithms, crowd workers, and experts in the classification of heart sound recordings. The development of a hybrid humanmachine framework ... 
Hurwitz Trees and Tropical Geometry
(University of Waterloo, 20160121)The lifting problem in algebraic geometry asks when a finite group G acting on a curve defined over characteristic p > 0 lifts to characteristic 0. One object used in the study of this problem is the Hurwitz tree, which ... 
A Hybrid Cellular Automata Model for the Role of Reactive Oxygen Species in Novel Tumour Treatments Strategies
(University of Waterloo, 20150121)Cancer is a disease that entails uncontrolled proliferation and a disruption of tissue function that often results in a poor clinical outcome. Furthermore, it has continued to elude any universal treatment or cure in part ... 
A Hybrid Model for ObjectOriented Software Maintenance
(University of Waterloo, 20080922)An objectoriented software system is composed of a collection of communicating objects that cooperate with one another to achieve some desired goals. The object is the basic unit of abstraction in an OO program; ... 
A Hybrid SymbolicNumeric Method for Multiple Integration Based on TensorProduct Series Approximations
(University of Waterloo, 2004)This work presents a new hybrid symbolicnumeric method for fast and accurate evaluation of multiple integrals, effective both in high dimensions and with high accuracy. In two dimensions, the thesis presents an adaptive ... 
HybridPointing Touch: A Technique to Switch Between Absolute and Relative Pointing on Large Touch Screens
(University of Waterloo, 20171025)We extend Forlines et al.'s idea of mixed absolute and relative "HybridPointing" to large multitouch displays. In our bimanual "CursorTap" interaction technique, one hand triggers a kinaesthetic relative pointing mode while ... 
Hydrodynamic Modeling of Dielectric Response in Graphene and Carbon Nanotubes
(University of Waterloo, 2006)This thesis studies two important carbon structures, graphene and carbon nanotubes, with the purpose of understanding how their threedimensional electron density distribution affects the way fast ions interact with them. ... 
Hydrodynamic Modelling of the Electronic Response of Carbon Nanotubes
(University of Waterloo, 20070208)The discovery of carbon nanotubes by Iijima in 1991 has created a torrent of new research activities. Research on carbon nanotubes ranges from studying their fundamental properties, such as their electron band structure ... 
Hydrodynamic Stability of Free Convection from an Inclined Elliptic Cylinder
(University of Waterloo, 2006)The steady problem of free convective heat transfer from an isothermal inclined elliptic cylinder and its stability is investigated. The cylinder is inclined at an arbitrary angle with the horizontal and immersed in an ... 
Hydrodynamics of the Yucatan peninsula carbonate aquifer: surface flow, inland propagation and mixing
(University of Waterloo, 20210428)This thesis is a collection of three investigations into the hydrodynamics and hydrogeology of the Yucatan Peninsula, Mexico. The first investigation models potential mangrovegroundwater interactions as a box model. We ... 
The hydrodynamics of twodimensional oscillating flows over ripples: the effect of asymmetries in ripple shape and currents
(University of Waterloo, 20170428)The research presented in this thesis involved consideration of three increasingly asymmetric oscillatory flows over two ripple profiles, one of which is asymmetric and represents a small deviation from a symmetric ripple. ... 
Hyperpfaffians in Algebraic Combinatorics
(University of Waterloo, 2006)The pfaffian is a classical tool which can be regarded as a generalization of the determinant. The hyperpfaffian, which was introduced by Barvinok, generalizes the pfaffian to higher dimension. This was further ... 
Hypothesis Testing in Finite Mixture Models
(University of Waterloo, 20071214)Mixture models provide a natural framework for unobserved heterogeneity in a population. They are widely applied in astronomy, biology, engineering, finance, genetics, medicine, social sciences, and other areas. An ... 
Hysteresis bifurcation and application to delayed FitzHughNagumo neural systems
(Elsevier, 202108)Hysteresis dynamics has been described in a vast number of biological experimental studies. Many such studies are phenomenological and a mathematical appreciation has not attracted enough attention. In the paper, we explore ...
