    • Non-local Quantum Systems with Infinite Entanglement 

      Liu, Li (University of Waterloo, 2022-08-18)
      The study of quantum entanglement under quantum information has mostly been done in the mathematical model of tensor product of Hilbert spaces. In infinite dimensions, this model cannot capture all cases of non-local ...
    • Nonlinear Dimensionality Reduction by Manifold Unfolding 

      Khajehpour Tadavani, Pooyan (University of Waterloo, 2013-09-27)
      Every second, an enormous volume of data is being gathered from various sources and stored in huge data banks. Most of the time, monitoring a data source requires several parallel measurements, which form a high-dimensional ...
    • Nonlinear Dimensionality Reduction with Side Information 

      Ghodsi Boushehri, Ali (University of Waterloo, 2006)
      In this thesis, I look at three problems with important applications in data processing. Incorporating side information, provided by the user or derived from data, is a main theme of each of these problems. <br /><br ...
    • Nonlinear Preconditioning Methods for Optimization and Parallel-In-Time Methods for 1D Scalar Hyperbolic Partial Differential Equations 

      Howse, Alexander James Maxwell (University of Waterloo, 2017-10-18)
      This thesis consists of two main parts, part one addressing problems from nonlinear optimization and part two based on solving systems of time dependent differential equations, with both parts describing strategies for ...
    • Nonlinear screening of external charge by doped graphene

      In the rst part of this thesis we discuss some details of properties of graphene and we explain the tight-binding approach to nd the energy spectrum in graphene. In the second part of the thesis, we solve a nonlinear ...
    • Nonlinear Wave Propagation in Brass Instruments 

      Resch, Janelle (University of Waterloo, 2013-01-25)
      The study of wave production and propagation is a common phenomenon seen within a variety of math and physics problems. This thesis in particular will investigate the production and propagation of sound waves through musical ...
    • Nonparametric Estimation in a Compound Mixture Model and False Discovery Rate Control with Auxiliary Information 

      Tian, Zhaoyang (University of Waterloo, 2020-05-15)
      In this thesis, we focus on two important statistical problems. The first is the nonparametric estimation in a compound mixture model with application to the malaria study. The second is the control of the false discovery ...
    • Nonribosomal Peptide Analog Identification with Tandem Mass Spectrometry 

      Shiwei, Li (University of Waterloo, 2014-07-29)
      Nonribosomal peptides (NRP) are a class of peptide secondary metabolites, usually produced by microorganisms like bacteria and fungi. NRP antibiotics, cytostatics, and immunosuppressants are in commercial use. ...
    • Nonribosomal Peptide Identification with Tandem Mass Spectrometry by Searching Structural Database 

      Yang, Lian (University of Waterloo, 2012-04-24)
      Nonribosomal peptides (NRP) are highlighted in pharmacological studies as novel NRPs are often promising substances for new drug development. To effectively discover novel NRPs from microbial fermentations, a crucial step ...
    • Nonrigid Image Registration Using Physically Based Models 

      Yi, Zhao (University of Waterloo, 2006)
      It is well known that biological structures such as human brains, although may contain the same global structures, differ in shape, orientation, and fine structures across individuals and at different times. Such ...
    • Nonsmooth Bifurcations of Mean Field Systems of Two-Dimensional Integrate and Fire Neurons 

      Nicola, Wilten; Campbell, Sue Ann (Society for Industrial and Applied Mathematics, 2016)
      Mean field systems have recently been derived that adequately predict the behaviors of large networks of coupled integrate-and-fire neurons [W. Nicola and S.A. Campbell, J. Comput. Neurosci., 35 (2013), pp. 87-108]. The ...
    • The Normal Distribution of ω(φ(m)) in Function Fields 

      Li, Li (University of Waterloo, 2008-01-28)
      Let ω(m) be the number of distinct prime factors of m. A celebrated theorem of Erdös-Kac states that the quantity (ω(m)-loglog m)/√(loglog m) distributes normally. Let φ(m) be Euler's φ-function. Erdös and Pomerance ...
    • Normal Mode Spectra of Idealized Baroclinic Waves
