    • Intersperse Coloring 

      Chiniforooshan, Ehsan Jay (University of Waterloo, 2007-09-27)
      In this thesis, we introduce the intersperse coloring problem, which is a generalized version of the hypergraph coloring problem. In the intersperse coloring problem, we seek a coloring that assigns at least l different ...
    • Interval Censoring and Longitudinal Survey Data 

      Pantoja Galicia, Norberto (University of Waterloo, 2007-09-11)
      Being able to explore a relationship between two life events is of great interest to scientists from different disciplines. Some issues of particular concern are, for example, the connection between smoking cessation and ...
    • Intervals with few Prime Numbers 

      Wolczuk, Dan (University of Waterloo, 2004)
      In this thesis we discuss some of the tools used in the study of the number of primes in short intervals. In particular, we discuss a large sieve density estimate due to Gallagher and two classical delay equations. ...
    • An introduction to Gerber-Shiu analysis 

      Huynh, Mirabelle (University of Waterloo, 2011-09-30)
      A valuable analytical tool to understand the event of ruin is a Gerber-Shiu discounted penalty function. It acts as a unified means of identifying ruin-related quantities which may help insurers understand their vulnerability ...
    • Invariant manifold theory for impulsive functional differential equations with applications 

      Church, Kevin E. M. (University of Waterloo, 2019-07-03)
      The primary contribution of this thesis is a development of invariant manifold theory for impulsive functional differential equations. We begin with an in-depth analysis of linear systems, immersed in a nonautonomous ...
    • Inverse Probability Weighted Estimating Equations for Randomized Trials in Transfusion Medicine 

      Cook, Richard J.; Lee, Ker-Ai; Cuerden, Meaghan; Cotton, Cecilia (Wiley, 2013-03-26)
      Thrombocytopenia is a condition characterized by extremely low platelet counts, which puts patients at elevated risk of morbidity and mortality because of bleeding. Trials in transfusion medicine are routinely designed ...
    • Inverse Problems and Self-similarity in Imaging 

      Ebrahimi Kahrizsangi, Mehran (University of Waterloo, 2008-08-06)
      This thesis examines the concept of image self-similarity and provides solutions to various associated inverse problems such as resolution enhancement and missing fractal codes. In general, many real-world inverse ...
    • Inverse Problems in Portfolio Selection: Scenario Optimization Framework 

      Bhowmick, Kaushiki (University of Waterloo, 2011-10-27)
      A number of researchers have proposed several Bayesian methods for portfolio selection, which combine statistical information from financial time series with the prior beliefs of the portfolio manager, in an attempt to ...
    • Inverted Index Partitioning Strategies for a Distributed Search Engine 

      Patel, Hiren (University of Waterloo, 2010-12-21)
      One of the greatest challenges in information retrieval is to develop an intelligent system for user and machine interaction that supports users in their quest for relevant information. The dramatic increase in the amount ...
    • Inverting Permutations In Place 

      Robertson, Matthew (University of Waterloo, 2015-08-17)
      We address the problem of quickly inverting the standard representation of a permutation on $n$ elements in place. First, we present a naive algorithm to do it using $O(\log n)$ extra bits in $O(n^2)$ time in the worst ...
    • Investigating Selection above a Multitouch Surface 

      Pyryeskin, Dmitry (University of Waterloo, 2012-10-25)
      Above-surface interaction is a new and exciting topic in the field of human-computer interaction (HCI). It focuses on the design and evaluation of systems that humans can operate by moving their hands in the space above ...
    • An Investigation of Methods for Missing Data in Hierarchical Models for Discrete Data 

      Ahmed, Muhamad Rashid (University of Waterloo, 2011-03-09)
      Hierarchical models are applicable to modeling data from complex surveys or longitudinal data when a clustered or multistage sample design is employed. The focus of this thesis is to investigate inference for discrete ...
    • An Investigation of Word Sense Disambiguation for Improving Lexical Chaining 

      Enss, Matthew (University of Waterloo, 2006)
      This thesis investigates how word sense disambiguation affects lexical chains, as well as proposing an improved model for lexical chaining in which word sense disambiguation is performed prior to lexical chaining. A ...
    • Investigations into quantum light-matter interactions, their approximations and applications 

      Funai, Nicholas (University of Waterloo, 2021-01-26)
      Devoting some thought to the interactions between light and matter quickly conjure a myriad of different possibilities; different models for light and matter, different possible interaction Hamiltonians, different simplifying ...
    • An Isogeny-Based Adaptor Signature Using SQISign 

      Gilchrist, Valerie (University of Waterloo, 2022-04-19)
      Transactions on blockchains can prove very costly, so as a solution to avoid these large costs, schemes involving payment channel networks have been developed. One approach to implementing these off-chain forms of payment ...
    • Iterated Function Systems with Place-Dependent Probabilities and the Inverse Problem of Measure Approximation Using Moments 

      Maki, Erik (University of Waterloo, 2016-10-25)
      The study of iterated function systems has close ties with the subject of fractal-based analysis. One important application is the approximation of a target object by the fixed point of a contractive iterated function ...
    • Iterative Edit-based Unsupervised Sentence Simplification 

      Kumar, Dhruv (University of Waterloo, 2020-07-28)
      We present a new iterative approach towards unsupervised edit-based sentence simplification. Our approach is guided by a scoring function to select simplified sentences generated after iteratively performing word and ...
    • Iterative Rounding Approximation Algorithms in Network Design 

      Shea, Marcus (University of Waterloo, 2010-05-21)
      Iterative rounding has been an increasingly popular approach to solving network design optimization problems ever since Jain introduced the concept in his revolutionary 2-approximation for the Survivable Network Design ...
    • Jaeger’s Strong 3-Flow Conjecture for Graphs in Low Genus Surfaces 

      de Jong, Jamie (University of Waterloo, 2020-05-05)
      In 1972, Tutte posed the 3-Flow Conjecture: that all 4-edge-connected graphs have a nowhere zero 3-flow. This was extended by Jaeger et al. (1992) to allow vertices to have a prescribed, possibly non-zero difference (modulo ...
    • A Java Toolkit for Distributed Evaluation of Hypergeometric Series 

      Chughtai, Fawad (University of Waterloo, 2004)
      Hypergoemetric Series are very important in mathematics and come up regularly when dealing with the precise definitions of constants such as <i>e</i>, &pi; and Apery's constant &sigmaf;(3). The evaluation of such series ...
