    • The Fourier algebra of a locally trivial groupoid 

      Marti Perez, Laura Raquel (University of Waterloo, 2012-01-10)
      The goal of this thesis is to define and study the Fourier algebra A(G) of a locally compact groupoid G. If G is a locally compact group, its Fourier-Stieltjes algebra B(G) and its Fourier algebra A(G) were defined by ...
    • Fractional Imputation for Ordinal and Mixed-type Responses with Missing Observations 

      She, Xichen (University of Waterloo, 2017-01-12)
      This thesis addresses two essential aspects of large scale public-use data files involving ordinal and mixed-type responses with missing observations: (i) the creation of single complete data sets with imputation for missing ...
    • Fractional refinements of integral theorems 

      Moore, Benjamin (University of Waterloo, 2021-07-09)
      The focus of this thesis is to take theorems which deal with ``integral" objects in graph theory and consider fractional refinements of them to gain additional structure. A classic theorem of Hakimi says that for an ...

      Fortes Tondello, Gustavo; Wehbe, Rina Renee; Orji, Rita; Ribeiro, Giovanni; Nacke, Lennart (Association for Computing Machinery, 2017-10-15)
      Player preferences for different gaming styles or game elements has been a topic of interest in human-computer interaction for over a decade. However, current models suggested by the extant literature are generally based ...
    • A Framework for Logical Structure Extraction from Software Requirements Documents 

      Rauf, Rehan (University of Waterloo, 2011-01-13)
      General purpose rich-text editors, such as MS Word are often used to author software requirements specifications. These requirements specifications contain many different logical structures, such as use cases, business ...
    • A Framework for Machine-Assisted Software Architecture Validation 

      Lichtner, Kurt (University of Waterloo, 2000)
      In this thesis we propose a formal framework for specifying and validating properties of software system architectures. The framework is founded on a model of software architecture description languages (ADLs) and uses ...
    • A Framework for Records Management in Relational Database Systems 

      Ataullah, Ahmed Ayaz (University of Waterloo, 2008-05-14)
      The problem of records retention is often viewed as simply deleting records when they have outlived their purpose. However, in the world of relational databases there is no standardized notion of a business record and its ...
    • A Framework for Resource Allocation in Time Critical Dynamic Environments Based on Social Welfare and Local Search and its Application to Healthcare 

      Shaft, Dean (University of Waterloo, 2014-02-14)
      This thesis provides an artificial intelligence approach for the problem of resource allocation in time-critical dynamic environments. Motivated by healthcare scenarios such as mass casualty incidents, we are concerned ...
    • A Framework for Software Component Interface Specification and Analysis 

      Hoyt, Matthew (University of Waterloo, 2001)
      Although markets are emerging for commercial off-the-shelf components (such as Sun JavaBeans), there are many barriers to widespread component adoption. This is due to the inherent `black-box' nature of software ...
    • A Framework for the Generation of Textures Representing Time-Dependent Changes in the Appearance of Dust Layers 

      Santos, Rebecca Linda Casinha (University of Waterloo, 2022-04-19)
      The perception of realism in computer generated images can be significantly enhanced by subtle visual cues. Among those, one can highlight the presence of dust on synthetic objects, which is often subject to temporal ...
    • Frameworks for Quantum Algorithms 

      Jeffery, Stacey (University of Waterloo, 2014-08-26)
      Due to the difficulty of constructing new quantum algorithms, frameworks that facilitate this construction are of great importance in quantum computing. These frameworks reduce the problem of coming up with a quantum ...
    • Free semigroup algebras and the structure of an isometric tuple 

      Kennedy, Matthew (University of Waterloo, 2011-06-28)
      An n-tuple of operators V=(V_1,…,V_n) acting on a Hilbert space H is said to be isometric if the corresponding row operator is an isometry. A free semigroup algebra is the weakly closed algebra generated by an isometric ...
    • FrictionalMonolith: A Monolithic Optimization-based Approach for Granular Flow with Contact-Aware Rigid-Body Coupling 

      Takahashi, Tetsuya; Batty, Christopher (Association for Computing Machinery, 2021)
      We propose FrictionalMonolith, a monolithic pressure-friction-contact solver for more accurately, robustly, and efficiently simulating two-way interactions of rigid bodies with continuum granular materials or inviscid ...
    • The Frobenius Problem in a Free Monoid 

      Xu, Zhi (University of Waterloo, 2009-08-21)
      Given positive integers c1,c2,...,ck with gcd(c1,c2,...,ck) = 1, the Frobenius problem (FP) is to compute the largest integer g(c1,c2,...,ck) that cannot be written as a non-negative integer linear combination of c1,c2,...,ck. ...
    • From Atoms to the Solar System: Generating Lexical Analogies from Text 

      Chiu, Pei-Wen Andy (University of Waterloo, 2006)
      A <em>lexical analogy</em> is two pairs of words (<em>w</em><sub>1</sub>, <em>w</em><sub>2</sub>) and (<em>w</em><sub>3</sub>, <em>w</em><sub>4</sub>) such that the relation between <em>w</em><sub>1</sub> and <em>w</em>< ...
    • From Fundamentals to Spectroscopic Applications of Density Functional Theory 

      Lyon, Keenan (University of Waterloo, 2020-05-29)
      Density functional theory (DFT) and its time-dependent counterpart (TDDFT) are crucial tools in material discovery, drug design, biochemistry, catalysis, and nanoscience. However, despite its exact theoretical basis, ...
    • From Gravity to Hopf Algebra Lattice Models 

      Osumanu, Abdulmajid (University of Waterloo, 2019-10-02)
      This thesis addresses three different problems related to quantum gravity. In the first problem we will discuss the two natural ways to encode gravity through geometric structures. One is the much acclaimed Einstein's ...
    • Fully Automated Translation of BoxTalk to Promela 

      Kajarekar, Tejas (University of Waterloo, 2011-08-26)
      Telecommunication systems are structured to enable incremental growth, so that new telecommunication features can be added to the set of existing features. With the addition of more features, certain existing features may ...
    • Function-valued Mappings and SSIM-based Optimization in Imaging 

      Otero, Daniel (University of Waterloo, 2015-08-27)
      In a few words, this thesis is concerned with two alternative approaches to imag- ing, namely, Function-valued Mappings (FVMs) and Structural Similarity Index Measure (SSIM)-based Optimization. Briefly, a FVM is a mathematical ...
    • Fundamental Limitations of Semi-Supervised Learning 

      Lu, Tyler (Tian) (University of Waterloo, 2009-05-05)
      The emergence of a new paradigm in machine learning known as semi-supervised learning (SSL) has seen benefits to many applications where labeled data is expensive to obtain. However, unlike supervised learning (SL), which ...
