Welcome to the Department of Applied Mathematics sub-community.

Research outputs are organized into collections by specific research type.

PLEASE NOTE: During the first phase of the UWSpace expansion project this community will be limited to two collections:

  1. Applied Mathematics Articles (Peer-Reviewed): Publications that have been peer-reviewed.
  2. Applied Mathematics Theses & Dissertations: Graduate student research required for degree completion.

Recent Submissions

  • 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 ...
  • Mathematical Aspects of Scalar-Tensor Field Theories 

    Horndeski, Gregory Walter (University of Waterloo, 2016-09-27)
    This thesis is based on a study of Lagrange scalar densities which are, in general, concomitants of the metric tensor gij (and its first and second derivatives) together with a scalar field ∅ (and its first derivative). ...
  • Infectious Disease Modeling with Interpersonal Contact Patterns as a Heterogeneous Network 

    Boneng, Joanna Felicia (University of Waterloo, 2016-09-26)
    In this thesis, we study deterministic compartmental epidemic models. The conventional mass-mixing assumption is replaced with infectious disease contraction occurring within a heterogeneous network. Modeling infectious ...
  • Early Warning Signals of Vaccine Scares. 

    Pananos, Athanasios (University of Waterloo, 2016-09-26)
    There exists strong evidence that vaccines are extremely effective in the prevention of pediatric infectious disease, yet despite this evidence, vaccine refusal is still popular amongst some parents. Existing mathematical ...
  • Non-compact groups, tensor operators and applications to quantum gravity 

    Sellaroli, Giuseppe (University of Waterloo, 2016-09-23)
    This work focuses on non-compact groups and their applications to quantum gravity, mainly through the use of tensor operators. Non-compact groups appear naturally if the space-time is of Lorentzian signature, but can also ...
  • Decoupling of Information Propagation from Energy Propagation 

    Jonsson, Robert H. (University of Waterloo, 2016-08-31)
    Information and energy are concepts central to our understanding of nature. Their relevance, in physics, ranges from fundamental physics, e.g., in black hole physics, all the way to future quantum computing technology. ...
  • A Taylor polynomial expansion line search for large-scale optimization 

    Hynes, Michael` (University of Waterloo, 2016-08-29)
    In trying to cope with the Big Data deluge, the landscape of distributed computing has changed. Large commodity hardware clusters, typically operating in some form of MapReduce framework, are becoming prevalent for ...
  • Stability of Nonlinear Functional Differential Equations by the Contraction Mapping Principle 

    Ramirez Ibanez, Cesar (University of Waterloo, 2016-08-29)
    Fixed point theory has a long history of being used in nonlinear differential equations, in order to prove existence, uniqueness, or other qualitative properties of solutions. However, using the contraction mapping ...
  • Halocline mixing due to heavy rainfall in the cenote's of the Yucatan Peninsula 

    Coutino, Aaron (University of Waterloo, 2016-08-23)
    The hydrodynamics of the Yucatan peninsula are extremely important due to the strain on water resources caused by increasing development along the eastern coast. The geology of the peninsula is unique geologically in that ...
  • Floating Bodies with Surface Tension 

    Chen, Hanzhe (University of Waterloo, 2016-08-18)
    Capillary phenomena have been studied by mathematicians and physicists for hundreds of years. In this thesis, both two-dimensional(2D) and three-dimensional(3D) bodies floating on an unbounded reservoir are studied based ...
  • Indirect Quantum Control: An Implementation-Independent Scheme 

    Layden, David (University of Waterloo, 2016-08-17)
    The ability to control quantum systems rapidly as compared to their coherence times is a central requirement for most proposed quantum technologies, such as quantum computing and quantum metrology. Improving the ratio of ...
  • Modeling Photoluminescence Decay Dynamics in Nanocrystals 

    Fernandes, Brian (University of Waterloo, 2016-08-17)
    Photoluminescence resulting from donor-acceptor recombination in gallium oxide nanocrystals was studied at short and long time scales for different nanocrystal sizes. A model for the intensity decay was formulated with two ...
  • Mathematical Modelling of Social Factors in Decision Making Processes at the Individual and Population Levels 

    Lang, John (University of Waterloo, 2016-08-11)
    In this thesis we apply mathematical modelling techniques to investigate the implications of social influence on decision making processes in two related contexts. The first problem concerns the mathematical modelling ...
  • A Model for Shear Response in Swimming Plankton 

    Shaw, Justin (University of Waterloo, 2016-08-11)
    The responses of zooplankton to the hydrodynamic variables of their environment, such as shear, are not well understood. We examine stochastic swimming models of the run and tumble type for plankton moving in a velocity ...
  • Infinite-dimensional Kalman Filtering and Sensor Placement Problem 

    Zhang, Minxin (University of Waterloo, 2016-08-03)
    One of the central problems in engineering is to estimate the state of a stochastic dynamic system from limited noisy measurements. A Kalman filter is commonly used for state estimation, which produces an unbiased optimal ...
  • Topographically generated internal waves and boundary layer instabilities 

    Soontiens, Nancy; Stastna, Marek; Waite, Michael L (American Institute of Physics, 2015-08)
    Flow over topography has been shown to generate finite amplitude internal waves upstream, over the topography and downstream. Such waves can interact with the viscous bottom boundary layer to produce vigorous instabilities. ...
  • Short-wave vortex instability in stratified flow 

    Bovard, Luke; Waite, Michael L (Elsevier, 2016-01)
    In this paper we investigate a new instability of the Lamb–Chaplygin dipole in a stratified fluid. Through numerical linear stability analysis, a secondary peak in the growth rate emerges at vertical scales about an order ...
  • Realizing surface driven flows in the primitive equations 

    Bembenek, Eric; Poulin, Francis J; Waite, Michael L (American Meteorological Society, 2015-05)
    The surface quasigeostrophic (SQG) model describes flows with surface buoyancy perturbations with no interior quasigeostrophic potential vorticity at small Rossby number Ro and O(1) Burger number, where quasigeostrophic ...
  • Dependence of model energy spectra on vertical resolution 

    Waite, Michael L (American Meteorological Society, 2016-03)
    Many high-resolution atmospheric models can reproduce the qualitative shape of the atmospheric kinetic energy spectrum, which has a power-law slope of −3 at large horizontal scales that shallows to approximately −5/3 in ...
  • Spectral energy balance in dry convective boundary layers 

    Sandham, James; Waite, Michael L (Taylor and Francis, 2015-04)
    Three-dimensional large-eddy simulations (LES) of the convective boundary layer over a domain of approximately 6 km are performed with the UCLA LES model. Simulations are forced with a constant surface heat flux and ...
