    • 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 ...
    • Jets, Vortices and Turbulence in Quasi-Geostrophic Magnetohydrodynamics 

      Tessier, Jonathan (University of Waterloo, 2022-07-28)
      In this thesis, we model the dynamics of the solar tachocline and the Earth's molten core using a shallow, rapidly rotating, and electrically conducting fluid on an f-plane. We explore the effects of a strong uniform ...
    • JITGNN: A Deep Graph Neural Network for Just-In-Time Bug Prediction 

      Keshavarz, Hossein (University of Waterloo, 2022-05-10)
      Just-In-Time (JIT) bug prediction is the problem of predicting software failure immediately after a change is submitted to the code base. JIT bug prediction is often preferred to other types of bug prediction (subsystem, ...
    • Join Cardinality Estimation Graphs: Analyzing Pessimistic and Optimistic Estimators Through a Common Lens 

      Chen, Jeremy Yujui (University of Waterloo, 2020-08-07)
      Join cardinality estimation is a fundamental problem that is solved in the query optimizers of database management systems when generating efficient query plans. This problem arises both in systems that manage relational ...
    • Juicy Haptic Design: Vibrotactile Embellishments Can Improve Player Experience in Games 

      Singhal, Tanay; Schneider, Oliver (ACM, 2021-05)
      Game designers and researchers employ a sophisticated language for producing great player experiences with concepts such as juici- ness, which refers to excessive positive feedback. However, much of their discourse excludes ...
    • The k-best paths in Hidden Markov Models. Algorithms and Applications to Transmembrane Protein Topology Recognition. 

      Golod, Daniil (University of Waterloo, 2009-08-26)
      Traditional algorithms for hidden Markov model decoding seek to maximize either the probability of a state path or the number of positions of a sequence assigned to the correct state. These algorithms provide only a ...
    • A k-Conjugacy Class Problem 

      Roberts, Collin (University of Waterloo, 2007-09-07)
      In any group G, we may extend the definition of the conjugacy class of an element to the conjugacy class of a k-tuple, for a positive integer k. When k = 2, we are forming the conjugacy classes of ordered pairs, when k ...
    • k-Connectedness and k-Factors in the Semi-Random Graph Process 

      Koerts, Hidde (University of Waterloo, 2022-12-20)
      The semi-random graph process is a single-player graph game where the player is initially presented an edgeless graph with n vertices. In each round, the player is offered a vertex u uniformly at random and subsequently ...
    • K-theory for C*-Algebras and for Topological Spaces 

      Xiao, Rui Philip (University of Waterloo, 2015-04-27)
      K-theory is the study of a collection of abelian groups that are invariant to C*-algebras or to locally compact Hausdorff spaces. These groups are useful for distinguishing C*-algebras and topological spaces, and they are ...
    • Kalman Filter Based Sensor Placement For Burgers Equation 

      Zonov, Stanislav (University of Waterloo, 2019-06-03)
      The algorithm used for determining sensor placement in this thesis will be based on the Kalman filter. This filter is very famous and its application are numerous - some examples include aircraft navigation, finance and ...
    • Kernel Methods in Computer-Aided Constructive Drug Design 

      Wong, William Wai Lun (University of Waterloo, 2009-05-14)
      A drug is typically a small molecule that interacts with the binding site of some target protein. Drug design involves the optimization of this interaction so that the drug effectively binds with the target protein while ...
    • Key Compression for Isogeny-Based Cryptosystems 

      Leonardi, Christopher (University of Waterloo, 2016-04-21)
      We present a method for key compression in quantum-resistant isogeny-based cryptosystems, which reduces storage and transmission costs of per-party public information by a factor of two, with no effect on the security level ...
    • Key establishment --- security models, protocols and usage 

      Ustaoglu, Berkant (University of Waterloo, 2008-07-30)
      Key establishment is the process whereby two or more parties derive a shared secret, typically used for subsequent confidential communication. However, identifying the exact security requirements for key establishment ...
    • KG-Pipeline: An Automated Knowledge Graph Generation Framework 

      Vezvaei, Alireza (University of Waterloo, 2022-09-16)
      Knowledge Graphs (KGs) have many applications, specifically in information retrieval and question answering. Community projects are conducted for building large-scale KGs with crowdsourcing, but building KGs with this ...
    • Kinematic Templates: Guiding Cursor Movement in End-User Drawing Tools 

      Fung, Richard Hai-Ping (University of Waterloo, 2009-08-26)
      This thesis presents kinematic templates, end-user drawing tools that influence the mouse cursor's movement within specific areas of a digital canvas. Two types of kinematic templates influence the cursor's movement: ...
