  • Particle Clustering and Sub-clustering as a Proxy for Mixing in Geophysical Flows 

    Chakraborty, Rishiraj (University of Waterloo, 2019-08-16)
    The Eulerian point of view is the traditional theoretical and numerical tool to describe fluid mechanics. Some modern computational fluid dynamics codes allow for the efficient simulation of particles, in turn facilitating ...
  • Prandtl number dependence of stratified turbulence 

    Legaspi, Jesse (University of Waterloo, 2019-08-15)
    Stratified turbulence is affected by buoyancy forces that suppress vertical motion, resulting in a horizontally-layered structure with quasi-two-dimensional vortices. The Prandtl number Pr quantifies the relative strengths ...
  • Model for the RE-TC thalamic circuit with application to childhood absence epilepsy 

    Newman, Jennie (University of Waterloo, 2019-08-12)
    Childhood absence epilepsy (CAE) is an idiopathic neurological disorder affecting roughly 2-8 children per 100,000 children worldwide. It is characterized by absence seizures, or short lapses in consciousness, and the ...
  • Relativistic Theory of the Interaction of Two-Dimensional Materials with Moving Charged Particles 

    Akbari, Kamran (University of Waterloo, 2019-08-08)
    Prompted by the recent surge of interest in integrating atomically thin layers of conducting materials into nanophotonic and nanoplasmonic devices; we propose, in this thesis, a theoretical framework to analyze the ...
  • Correlation and Communication via a Quantum Field 

    Simidzija, Petar (University of Waterloo, 2019-07-15)
    We study the ability of qubit detectors to i) extract correlations from, and ii) transmit quantum information through, a quantum field. We start by perturbatively studying the harvesting of correlations from thermal and ...
  • 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 ...
  • 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 ...
  • Numerical Simulations of Internal Solitary and Solitary-Like Waves: Wave Interactions and Instabilities 

    Xu, Chengzhu (University of Waterloo, 2019-05-31)
    Internal solitary and solitary-like waves (ISWs) are commonly observed in stably stratified fluids such as the Earth's atmosphere and oceans. As these waves interact with other physical processes and/or move through a ...
  • Estimation for Linear and Semi-linear Infinite-dimensional Systems 

    Germ, Fabian (University of Waterloo, 2019-05-21)
    Estimating the state of a system that is not fully known or that is exposed to noise has been an intensely studied problem in recent mathematical history. Such systems are often modelled by either ordinary differential ...
  • Three Results in Quantum Physics 

    Huq, Jaron Meser (University of Waterloo, 2019-05-09)
    This thesis is split into three disjoint sections. The first deals with two practical issues regarding the use of unitary 2-designs. A simplified description of how to generate elements of the smallest known unitary 2-design ...
  • Microswimmer Propulsion by Two Steadily Rotating Helical Flagella 

    Shum, Henry (MDPI, 2019-01-01)
    Many theoretical studies of bacterial locomotion adopt a simple model for the organism consisting of a spheroidal cell body and a single corkscrew-shaped flagellum that rotates to propel the body forward. Motivated by ...
  • Harnessing surface-bound enzymatic reactions to organize microcapsules in solution 

    Shklyaev, Oleg E.; Shum, Henry; Sen, Ayusman; Balazs, Anna C. (American Association for the Advancement of Science (AAAS), 2016-03)
    By developing new computational models, we examine how enzymatic reactions on an underlying surface can be harnessed to direct the motion and organization of reagent-laden microcapsules in a fluid-filled microchannel. In ...
  • The effects of flagellar hook compliance on motility of monotrichous bacteria: A modeling study 

    Shum, H.; Gaffney, E. A. (AIP Publishing, 2012-06)
    A crucial structure in the motility of flagellated bacteria is the hook, which connects the flagellum filament to the motor in the cell body. Early mathematical models of swimming bacteria assume that the helically shaped ...
  • Harnessing catalytic pumps for directional delivery of microparticles in microchambers 

    Das, Sambeeta; Shklyaev, Oleg E.; Altemose, Alicia; Shum, Henry; Ortiz-Rivera, Isamar; Valdez, Lyanne; Mallouk, Thomas E.; Balazs, Anna C.; Sen, Ayusman (Springer Nature, 2017-02-17)
    The directed transport of microparticles in microfluidic devices is vital for efficient bioassays and fabrication of complex microstructures. There remains, however, a need for methods to propel and steer microscopic cargo ...
  • Convective flow reversal in self-powered enzyme micropumps 

    Ortiz-Rivera, Isamar; Shum, Henry; Agrawal, Arjun; Sen, Ayusman; Balazs, Anna C. (Proceedings of the National Academy of Sciences, 2016-02-22)
    Surface-bound enzymes can act as pumps that drive large-scale fluid flows in the presence of their substrates or promoters. Thus, enzymatic catalysis can be harnessed for "on demand" pumping in nano-and microfluidic devices ...
  • Synthetic quorum sensing in model microcapsule colonies 

    Shum, Henry; Balazs, Anna C. (Proceedings of the National Academy of Sciences, 2017-07-24)
    Biological quorum sensing refers to the ability of cells to gauge their population density and collectively initiate a new behavior once a critical density is reached. Designing synthetic materials systems that exhibit ...
  • An Integral Projection Model for Giant Hogweed 

    Drake, Jonathan Peter (University of Waterloo, 2019-02-04)
    In this thesis I investigate the impact that the choice of model may have on predictions of giant hogweed population dynamics. It has been shown in two case studies that population growth rates predicted by matrix population ...
  • What is a field, what is a particle?...what about algebras? 

    Papageorgiou, Maria-Eftychia (University of Waterloo, 2019-01-25)
    Much of the structure of quantum field theory (QFT) is predicated on the principle of locality. Adherence to locality is achieved in Algebraic QFT (AQFT) by the association of algebras of observables with regions of ...
