Discrete Logarithm Cryptography
(University of Waterloo, 2010-04-27)The security of many cryptographic schemes relies on the intractability of the discrete logarithm problem (DLP) in groups. The most commonly used groups to deploy such schemes are the multiplicative (sub)groups of finite ... -
Discrete Path Planing Strategies for Coverage and Multi-Robot Rendezvous
(University of Waterloo, 2014-01-22)This thesis addresses the problem of motion planning for autonomous robots, given a map and an estimate of the robot pose within it. The motion planning problem for a mobile robot can be defined as computing a trajectory ... -
Discrete Quantum Walks on Graphs and Digraphs
(University of Waterloo, 2018-09-26)This thesis studies various models of discrete quantum walks on graphs and digraphs via a spectral approach. A discrete quantum walk on a digraph $X$ is determined by a unitary matrix $U$, which acts on complex functions ... -
Discrete viscous sheets
(Association for Computing Machinery, 2012-07)We present the first reduced-dimensional technique to simulate the dynamics of thin sheets of viscous incompressible liquid in three dimensions. Beginning from a discrete Lagrangian model for elastic thin shells, we apply ... -
Discrete-Time Quantum Walk - Dynamics and Applications
(University of Waterloo, 2010-01-25)This dissertation presents investigations on dynamics of discrete-time quantum walk and some of its applications. Quantum walks has been exploited as an useful tool for quantum algorithms in quantum computing. Beyond quantum ... -
Discretionary capitalisation of R&D expenditures in Canada and Australia

Discretize and Conquer: Scalable Agglomerative Clustering in Hamming Space
(University of Waterloo, 2019-01-11)Clustering is one of the most fundamental tasks in many machine learning and information retrieval applications. Roughly speaking, the goal is to partition data instances such that similar instances end up in the same group ... -
Discrimination in Insurance Pricing
(University of Waterloo, 2023-04-10)Discrimination is an ongoing problem in the insurance industry that persists, regardless of intent, when the insurer blinds the pricing process from socially controversial or legally prohibited input. In this thesis, we ... -
A Discriminative Locally-Adaptive Nearest Centroid Classifier for Phoneme Classification
(University of Waterloo, 2012-08-31)Phoneme classification is a key area of speech recognition. Phonemes are the basic modeling units in modern speech recognition and they are the constructive units of words. Thus, being able to quickly and accurately classify ... -
Discriminators of Integer Sequences
(University of Waterloo, 2017-08-28)The discriminator of an integer sequence \textbf{s} = $(s(n))_{n \geq 0}$, first introduced by Arnold, Benkoski and McCabe in 1985, is the function $D_s (n)$ that maps the integer $n \geq 1$ to the smallest positive integer ... -
The Discursive Construction of Punk: Language and Identity in Russia’s Punk-Rock ‘Subculture’
(University of Waterloo, 2007-05-01)Beginning in the mid 1980s the practices of Soviet youth became a scene of heightened academic interest as western scholars eagerly turned their attention to the changing ‘subcultural’ realities of youth in the wake of the ... -
The Discursive Construction of Russian-German Identity in Interviews with Russlanddeutsche University Students
(University of Waterloo, 2007-06-28)In this sociolinguistic study, qualitative interviews were used in examining discursive identity construction among russlanddeutsche Aussiedler. The interview group was composed of russlanddeutsche university students ... -
Disease Dynamics And Costly Punishment Can Foster Socially Imposed Monogamy
(Nature Publishing Group, 2016-04-01)Socially imposed monogamy in humans is an evolutionary puzzle because it requires costly punishment by those who impose the norm. Moreover, most societies were-and are-polygynous; yet many larger human societies transitioned ... -
Disease Interventions Can Interfere With One Another Through Disease-Behaviour Interactions
(Public Library of Science, 2015-06-01)Theoretical models of disease dynamics on networks can aid our understanding of how infectious diseases spread through a population. Models that incorporate decision-making mechanisms can furthermore capture how behaviour-driven ... -
Disengagement during lectures: Media multitasking and mind wandering in university classrooms
(Elsevier, 2019-04-01)In university classrooms, the use of laptops or smartphones for purposes unrelated to the lecture is on the rise. Consequently, it is important to understand how frequently this behavior occurs, to track whether it increases ... -
Disentangled Representation Learning for Stylistic Variation in Neural Language Models
(University of Waterloo, 2018-08-14)The neural network has proven to be an effective machine learning method over the past decade, prompting its usage for modelling language, among several other domains. However, the latent representations learned by these ... -
Disentangled Syntax and Semantics for Stylized Text Generation
(University of Waterloo, 2020-09-21)Neural network based methods are widely used in text generation. The end-to-end training of neural networks directly optimizes the text generation pipeline has been proved powerful in various tasks, including machine ... -
Disentanglement of Syntactic Components for Text Generation
(University of Waterloo, 2022-02-18)Modelling human generated text, i.e., natural language data, is an important challenge in artificial intelligence. A good AI program should be able to understand and analyze natural language, and generate fluent and accurate ... -
Disentangling the Posthuman: Broadening Perspectives of Human/Machine Mergers through Inter-relational Subjectivity
(University of Waterloo, 2019-12-13)In the conclusion of How We Became Posthuman, N. Katharine Hayles states that the terror of posthumanism comes from its dual connotation of superseding the human and coming after it, implying that the days of being human ... -
Disinfection By-Product Formation in Drinking Water Treated with Chlorine Following UV Photolysis & UV/H<sub>2</sub>O<sub>2</sub>
(University of Waterloo, 2005)ABSTRACT As far back as the early 1900?s when it was discovered that water could be a mode of transmitting diseases, chlorine was used to disinfect water. In the 1970?s, the formation of disinfection by-products ...
