      Traditionally, the spread of infectious diseases in human populations has been modelled with static parameters. These parameters, however, can change when individuals change their behaviour. If these changes are themselves ...
    • No Zombie Types: Liveness-Based Justification For Monotonic Gradual Types 

      Zi, Yangtian (University of Waterloo, 2021-08-24)
      Gradual type systems with the monotonic dynamic semantics, such as HiggsCheck implementing SafeTypeScript, are able to achieve decent performance, making them a viable option for JavaScript programmers seeking run-time-checkable ...
    • NOCH: A framework for biologically plausible models of neural motor control 

      DeWolf, Travis (University of Waterloo, 2010-01-20)
      This thesis examines the neurobiological components of the motor control system and relates it to current control theory in order to develop a novel framework for models of motor control in the brain. The presented framework ...
    • Node-Weighted Prize Collecting Steiner Tree and Applications 

      Sadeghian Sadeghabad, Sina (University of Waterloo, 2013-05-23)
      The Steiner Tree problem has appeared in the Karp's list of the first 21 NP-hard problems and is well known as one of the most fundamental problems in Network Design area. We study the Node-Weighted version of the Prize ...
    • Noisy Embezzlement of Entanglement and Applications to Entanglement Dilution 

      Lasecki, Dariusz (University of Waterloo, 2019-05-23)
      In this thesis we present the concept of embezzlement of entanglement, its properties, efficiency, possible generalizations and propose the linear programming characterization of this phenomenon. Then, we focus on the noisy ...
    • Noisy Interactive Quantum Communication 

      Shayeghi, Ala (University of Waterloo, 2020-08-25)
      We consider the problem of implementing two-party interactive quantum communication over noisy channels, a necessary endeavor if we wish to fully reap quantum advantages for communication. For an arbitrary protocol with n ...
    • 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 ...
    • Non-Constructivity in Security Proofs 

      Soundararajan, Priya (University of Waterloo, 2018-09-10)
      In the field of cryptography, one generally obtains assurances for the security of a cryptographic protocol by giving a reductionist security proof, which is comprised of a reduction from breaking a mathematical problem ...
    • The non-injective hidden shift problem 

      Gharibi, Mirmojtaba (University of Waterloo, 2012-01-19)
      In this work, we mostly concentrate on the hidden shift problem for non-injective functions. It is worthwhile to know that the query complexity of the non-injective hidden shift problem is exponential in the worst case by ...
    • A Non-Intersecting R-Tree 

      Langendoen, Kyle Jacob (University of Waterloo, 2021-05-12)
      Indexes for multidimensional data based on the R-Tree are popularly used by databases for a wide range of applications. Such index trees support point and range queries but are costly to construct over datasets of millions ...
    • Non-Intrusive Computing 

      Chen, Hao (University of Waterloo, 2008-12-17)
      Pervasive computing is an important trend today. It concerns devices and services in a smart space that interact with users in a simple, natural, and harmonious way. Many problems in this domain have been studied from ...
    • Non-Isotopic Symplectic Surfaces in Products of Riemann Surfaces 

      Hays, Christopher (University of Waterloo, 2006)
      <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=iso-8859-1"> </head> Let &Sigma;<em><sub>g</sub></em> be a closed Riemann surface of genus <em>g</em>. Generalizing Ivan Smith's construction, ...
    • Non-linear Effects on Stopping of Fast Moving Molecular Ions Through Solids 

      Wilson, Tyler (University of Waterloo, 2007-06-27)
      This thesis studies the non-linear (Barkas) effects on stopping of fast moving molecular ions through solids. We model the solid target by a rigid lattice of positive ion cores surrounded by a gas of electrons. To model ...
