    • On the structure of invertible elements in certain Fourier-Stieltjes algebras 

      Thamizhazhagan, Aasaimani (University of Waterloo, 2021-08-27)
      Let $G$ be a locally compact group. The Fourier-Stieltjes and Fourier algebras, $B(G)$ and $A(G)$ are defined by Eymard to act as dual objects of the measure and group algebras, $M(G)$ and $L^1(G)$, in a sense generalizing ...
    • On the Structure of Nonnegative Semigroups of Matrices 

      Williamson, Peter (University of Waterloo, 2009-08-18)
      The results presented here are concerned with questions of decomposability of multiplicative semigroups of matrices with nonnegative entries. Chapter 1 covers some preliminary results which become useful in the remainder ...
    • On the Succinct Representation of Equivalence Classes 

      El-Zein, Hicham (University of Waterloo, 2014-12-17)
      Given a set of n elements that are partitioned into equivalence classes, we study the problem of assigning unique labels to these elements in order to support the query that asks whether the elements corresponding to two ...
    • On the Techniques for Efficient Sampling, Uncertainty Quantification and Robust Control of Stochastic Multiscale Systems 

      Kimaev, Grigoriy (University of Waterloo, 2020-08-25)

    • On the theoretical importance of distinguishing between intentional and unintentional types of Mind Wandering 

      Seli, Paul (University of Waterloo, 2015-07-22)
      When introduced to mainstream psychological research nearly a decade ago, mind wandering was defined as unintentional, internally-focused thought. The requirement of an absence of intention was critical in terms of the ...
    • On the Use of Directed Moves for Placement in VLSI CAD 

      Vorwerk, Kristofer (University of Waterloo, 2009-07-31)
      Search-based placement methods have long been used for placing integrated circuits targeting the field programmable gate array (FPGA) and standard cell design styles. Such methods offer the potential for high-quality ...
    • On the Use of MODIS for Lake and Land Surface Temperature Investigations in the Regions of Great Bear Lake and Great Slave Lake, N.W.T. 

      Kheyrollah Pour, Homa (University of Waterloo, 2011-08-19)
      Lake surface temperature (LSTlake) can be obtained and studied in different ways: using in situ measurements, satellite imagery and modeling. Collecting spatially representative in situ data over lakes, especially for large ...
    • On the Utility of Adding An Abstract Domain and Attribute Paths to SQL 

      Ma, Weicong (University of Waterloo, 2018-04-30)
      Albeit its popularity today, RDBMS and the relational model still have many limitations. For example, one needs to pay premature attention to naming issues in the schema designing phase; and the syntax for conjunctive ...
    • On the Verge: Activating Public Space in the Periphery 

      Young, Alana (University of Waterloo, 2009-06-19)
      This thesis examines the suburban verge’s latent potential as an alternative public space. It is located between the boundaries of private properties and public streets, where territorial boundaries and ownership are ...
    • On Tolerant Testing and Tolerant Junta Testing 

      Levi, Amit (University of Waterloo, 2020-07-08)
      Over the past few decades property testing has became an active field of study in theoretical computer science. The algorithmic task is to determine, given access to an unknown large object (e.g., function, graph, probability ...
    • On Transcendence of Irrationals with Non-eventually Periodic b-adic Expansions 

      Koltunova, Veronika (University of Waterloo, 2010-05-18)
      It is known that almost all numbers are transcendental in the sense of Lebesgue measure. However there is no simple rule to separate transcendental numbers from algebraic numbers. Today research in this direction is about ...
    • On Two Combinatorial Optimization Problems in Graphs: Grid Domination and Robustness 

      Fata, Elaheh (University of Waterloo, 2013-08-30)
      In this thesis, we study two problems in combinatorial optimization, the dominating set problem and the robustness problem. In the first half of the thesis, we focus on the dominating set problem in grid graphs and present ...
    • On Using Embeddings for Ownership Verification of Graph Neural Networks 

      Waheed, Asim (University of Waterloo, 2023-08-11)
      Graph neural networks (GNNs) have emerged as a state-of-the-art approach to model and draw inferences from large scale graph-structured data in various application settings such as social networking. The primary goal of a ...
    • On Using Storage and Genset for Mitigating Power Grid Failures 

      Singla, Sahil (University of Waterloo, 2013-04-25)
      Although modern society is critically reliant on power grids, even modern power grids are subject to unavoidable outages due to storms, lightning strikes, and equipment failures. The situation in developing countries is ...
    • On Vegh's Strongly Polynomial Algorithm for Generalized Flows 

      Lo, Venus Hiu Ling (University of Waterloo, 2014-05-22)
      This thesis contains an exposition of the new strongly polynomial algorithm for the generalized flow problem by Laszlo Vegh (2013). It has been a long-standing open question whether such an algorithm exists, until it was ...
    • On Walking 

      Neault, Sarah Michelle (University of Waterloo, 2010-12-03)
      Imagine the anatomy of architecture as a complex system, where the form is the result of generative processes, the material properties of the components, and their patterns of assembly. Within this paradigm, surface is ...
    • On Yonge Street 

      Kalfakis, Eleftheria (University of Waterloo, 2010-08-26)
      Yonge Street is a unique urban resource for the City of Toronto. It acts as the central nervous system uniting local, suburban and out-of-town populations with both surface and underground networks. It has transformed to ...
    • On-Chip Power Supply Noise: Scaling, Suppression and Detection 

      Karim, Tasreen (University of Waterloo, 2012-08-24)
      Design metrics such as area, timing and power are generally considered as the primary criteria in the design of modern day circuits, however, the minimization of power supply noise, among other noise sources, is appreciably ...
