    • Parking Functions and Related Combinatorial Structures. 

      Rattan, Amarpreet (University of Waterloo, 2001)
      The central topic of this thesis is parking functions. We give a survey of some of the current literature concerning parking functions and focus on their interaction with other combinatorial objects; namely noncrossing ...
    • Parlez-vous le hate?: Examining topics and hate speech in the alternative social network Parler 

      Ward, Ethan (University of Waterloo, 2021-12-23)
      Over the past several years, many “alternative” social networks have sprung up, with an emphasis on minimal moderation and protection of free speech. Although they claim to be politically neutral, they have been a haven ...

      Chakraborty, Rishiraj (University of Waterloo, 2019-08-16)
      The Eulerian point of view is the traditional theoretical and numerical tool to describe fluid mechanics. Some modern computational fluid dynamics codes allow for the efficient simulation of particles, in turn facilitating ...
    • A Particle Filter Method of Inference for Stochastic Differential Equations 

      Subramani, Pranav (University of Waterloo, 2022-05-31)
      Stochastic Differential Equations (SDE) serve as an extremely useful modelling tool in areas including ecology, finance, population dynamics, and physics. Yet, parameter inference This thesis explores this latter approach. ...
    • Partition Algebras and Kronecker Coefficients 

      Marcott, Cameron (University of Waterloo, 2015-08-28)
      Classical Schur-Weyl duality relates the representation theory of the general linear group to the representation theory of the symmetric group via their commuting actions on tensor space. With the goal of studying Kronecker ...
    • Partitioning Pauli Operators: in Theory and in Practice 

      Jena, Andrew (University of Waterloo, 2019-09-04)
      Measuring the expectation value of Pauli operators on prepared quantum states is a fundamental task in the variational quantum eigensolver. Simultaneously measuring sets of operators allows for fewer measurements and an ...
    • Passenger Response to Driving Style in an Autonomous Vehicle 

      Dillen, Nicole (University of Waterloo, 2019-09-23)
      Despite rapid advancements in automated driving systems (ADS), current human-computer interaction research tends to focus more on the safety driver in lower level vehicles. The future of automated driving lies in higher ...
    • Password Advice Shouldn't Be Boring: Visualizing Password Guessing Attacks 

      Zhang-Kennedy, Leah; Chiasson, Sonia; Biddle, Robert (IEEE, 2013-09)
      Users are susceptible to password guessing attacks when they create weak passwords. Despite an abundance of text-based password advice, it appears insufficient to help home users create strong memorable passwords. We propose ...
    • Path Queries in Weighted Trees 

      Zhou, Gelin (University of Waterloo, 2012-08-24)
      Trees are fundamental structures in computer science, being widely used in modeling and representing different types of data in numerous computer applications. In many cases, properties of objects being modeled are ...
    • Path Tableaux and the Combinatorics of the Immanant Function 

      Tessier, Rebecca (University of Waterloo, 2013-04-29)
      Immanants are a generalization of the well-studied determinant and permanent. Although the combinatorial interpretations for the determinant and permanent have been studied in excess, there remain few combinatorial ...
    • A Path to DOT: Formalizing Scala with Dependent Object Types 

      Rapoport, Marianna (University of Waterloo, 2019-12-13)
      The goal of my thesis is to enable formal reasoning about the Scala programming language. To that end I present a core calculus that formalizes Scala's i) essential features in a ii) type-safe way and is iii) easy to extend ...
    • Patterns of Search Result Examination: Query to First Action. 

      Abualsaud, Mustafa; Smucker, Mark (ACM, 2019-11-03)
      To determine key factors that affect a user's behavior with search results, we conducted a controlled eye-tracking study of users completing search tasks using both desktop and mobile devices. We focus our investigation ...
    • Peer-Based Intelligent Tutoring Systems: A Corpus-Oriented Approach 

      Champaign, John (University of Waterloo, 2012-05-11)
      In this thesis, we present an artificial intelligence approach for tutoring students in environments where there is a large repository of possible learning objects (e.g. texts, videos). In particular, we advocate that ...
    • Penalized Regression for Interval-Censored Times of Disease Progression: Selection of HLA Markers in Psoriatic Arthritis 

      Wu, Ying; Cook, Richard J. (Wiley, 2015-09)
      Times of disease progression are interval-censored when progression status is only known at a series of assessment times. This situation arises routinely in clinical trials and cohort studies when events of interest are ...
    • Pencil Light Transport 

      Steigleder, Mauro (University of Waterloo, 2005)
      Global illumination is an important area of computer graphics, having direct applications in architectural visualization, lighting design and entertainment. Indirect illumination effects such as soft shadows, color ...
    • People know how diverse their music recommendations should be; why don’t we? 

      Robinson, Kyle (University of Waterloo, 2021-02-17)
      While many researchers have proposed various ways of quantifying recommendation list diversity, these approaches have had little input from users on their own perceptions and preferences in seeking diversity. Through a ...
    • Peptide Sequencing with Deep Learning 

      Qiao, Rui (University of Waterloo, 2020-09-30)
      In shotgun proteomics, de novo peptide sequencing from tandem mass spectrometry data is the key technology for finding new peptide or protein sequences. It has successful applications in assembling monoclonal antibody ...
    • Perfect Hash Families: Constructions and Applications 

      Kim, Kyung-Mi (University of Waterloo, 2003)
      Let <b>A</b> and <b>B</b> be finite sets with |<b>A</b>|=<i>n</i> and |<b>B</b>|=<i>m</i>. An (<i>n</i>,<i>m</i>,<i>w</i>)-<i>perfect hash</i> family</i> is a collection <i>F</i> of functions from <b>A</b> to <b>B</b> ...
    • Performance Analysis of Distributed Virtual Environments 

      Kwok, Kin Fai Michael (University of Waterloo, 2006)
