High-Order Numerical Methods in Lake Modelling
(University of Waterloo, 2014-06-18)The physical processes in lakes remain only partially understood despite successful data collection from a variety of sources spanning several decades. Although numerical models are already frequently employed to simulate ... -
High-Performance Concurrent Memory Allocation
(University of Waterloo, 2022-05-25)Memory management takes a sequence of program-generated allocation/deallocation requests and attempts to satisfy them within a fixed-sized block of memory while minimizing the total amount of memory used. A general-purpose ... -
High-Resolution Analysis of Snow Albedo Interactions in the Arctic
(University of Waterloo, 2022-08-23)The Snow Albedo Feedback (SAF) is an important contributor to Arctic warming, however models disagree significantly on the strength of this effect. Previous work has investigated the influence of vegetation on surface ... -
High-Resolution Numerical Simulations of Wind-Driven Gyres
(University of Waterloo, 2011-08-26)The dynamics of the world's oceans occur at a vast range of length scales. Although there are theories that aid in understanding the dynamics at planetary scales and microscales, the motions in between are still not yet ... -
Higher Gauge Theory and Discrete Geometry
(University of Waterloo, 2023-06-05)In four dimensions, gravity can be seen as a constrained topological model. This provides a natural way to construct quantum gravity models, since topological models are relatively straightforward to quantize. Difficulty ... -
Higher Order Random Walks, Local Spectral Expansion, and Applications
(University of Waterloo, 2020-09-16)The study of spectral expansion of graphs and expander graphs has been an extremely fruitful line of research in Mathematics and Computer Science, with applications ranging from random walks and fast sampling to optimization. ... -
Higher-Dimensional Kloosterman Sums and the Greatest Prime Factor of Integers of the Form a_1a_2\cdots a_{k+1}+1
(University of Waterloo, 2007-08-29)We consider the greatest prime factors of integers of certain form. -
Higher-order Losses and Optimization for Low-level and Deep Segmentation
(University of Waterloo, 2021-12-21)Regularized objectives are common in low-level and deep segmentation. Regularization incorporates prior knowledge into objectives or losses. It represents constraints necessary to address ill-posedness, data noise, outliers, ... -
Highly Non-Convex Crossing Sequences
(University of Waterloo, 2012-05-18)For a given graph, G, the crossing number crₐ(G) denotes the minimum number of edge crossings when a graph is drawn on an orientable surface of genus a. The sequence cr₀(G), cr₁(G), ... is said to be the crossing sequence ... -
Highway Development Decision-Making Under Uncertainty: Analysis, Critique and Advancement
(University of Waterloo, 2011-01-20)While decision-making under uncertainty is a major universal problem, its implications in the field of transportation systems are especially enormous; where the benefits of right decisions are tremendous, the consequences ... -
Hilbert space operators with compatible off-diagonal corners
(Elsevier, 2018-08-15)Given a complex, separable Hilbert space H, we characterize those operators for which ‖PT(I−P)‖=‖(I−P)TP‖ for all orthogonal projections P on H. When H is finite-dimensional, we also obtain a complete characterization of ... -
Homologous Gene Finding with a Hidden Markov Model
(University of Waterloo, 2007-01-12)The homology search problem and the gene finding problem are two fundamental problems in bioinformatics. The homology search problem is to find the homologous regions of two biological sequences; the gene finding problem ... -

Homomorphic Encryption
(University of Waterloo, 2013-01-24)In this thesis, we provide a summary of fully homomorphic encryption, and in particular, look at the BGV encryption scheme by Brakerski, Gentry, and Vaikuntanathan; as well the DGHV encryption scheme by van Dijk, Gentry, ... -
Homotopy algorithms for solving structured determinantal systems
(University of Waterloo, 2020-12-17)Multivariate polynomial systems arising in numerous applications have special structures. In particular, determinantal structures and invariant systems appear in a wide range of applications such as in polynomial optimization ... -
Honest Approximations to Realistic Fault Models and Their Applications to Efficient Simulation of Quantum Error Correction
(University of Waterloo, 2014-04-25)Understanding the performance of realistic noisy encoded circuits is an important task for the development of large-scale practical quantum computers. Specifically, the development of proposals for quantum computation must ... -
Honkling: In-Browser Personalization for Ubiquitous Keyword Spotting
(University of Waterloo, 2019-12-19)Used for simple voice commands and wake-word detection, keyword spotting (KWS) is the task of detecting pre-determined keywords in a stream of utterances. A common implementation of KWS involves transmitting audio samples ... -
House Price Risk in Mortgage Contracts
(University of Waterloo, 2016-01-25)Research has shown that mortgage default is closely related to house prices. When house prices fall the borrower has an incentive to default. Since default incurs substantial cost to the lender, the borrower and many other ... -
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, 2016-01)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 ...
