• Analysis of a two fluid model and its comparison with MHD system 

  Shen, Shengyi (2019-05-22)

  In this thesis, we study a two fluid system which describes the motion of two charged particles in a strict neutral incompressible plasma. We study the well-posdness of the system in both space dimensions two and three. ...
• K-theory correspondences and the Fourier-Mukai transform 

  Hudson, Daniel (2019-05-02)

  The goal of this thesis is to give an introduction to the geometric picture of bivariant K-theory developed by Emerson and Meyer building on the ideas Connes and Skandalis, and then to apply this machinery to give a geometric ...
• Ramp approximations of finitely steep sigmoid control functions in soft-switching ODE networks 

  Quee, Graham (2019-04-24)

  In models for networks of regulatory interactions in biological molecules, the sigmoid relationship between concentration of regulating bodies and the production rates they control has lead to the use of continuous time ...
• Minimax robust designs for misspecified regression models 

  Shi, Peilin (2018-11-09)

  Minimax robust designs are studied for regression models with possible misspecified response functions. These designs, minimizing the maximum of the mean squared error matrix, can control the bias caused by model ...
• Relative equilibria in the curved N-body problem 

  Alhowaity, Sawsan Salem (Canadian Mathematical Bulletin, 2018-08-22)

  We consider the curved N-body problem, N > 2, on a surface of constant Gaussian curvature κ ≠ 0; i.e., on spheres S2κ, for κ > 0, and on hyperbolic manifolds H2κ, for κ < 0. Our goal is to define and study relative equilibria, ...
• Waves generated by a load moving on an ice sheet over water 

  Nugroho, Widijanto Satyo (2018-07-25)

  A load moving on a floating ice sheet produces a deflection of the ice sheet. In this Dissertation, three problems associated with mathematical models of the ice water system are examined. A mathematical model involving ...
• Optimal regression design under second-order least squares estimator: theory, algorithm and applications 

  Yeh, Chi-Kuang (2018-07-23)

  In this thesis, we first review the current development of optimal regression designs under the second-order least squares estimator in the literature. The criteria include A- and D-optimality. We then introduce a new ...
• Neural networks and neural fields: discrete and continuous space neural models 

  Edwards, Roderick (2018-07-12)

  'Attractor' neural network models have useful properties, but biology suggests that more varied dynamics may be significant. Even the equations of the Hopfield network, without the constraint of symmetry, can have complex ...
• Mappings on triangular algebras 

  Cheung, Wai-Shun (2018-05-07)

  In this dissertation, we study certain types of linear mappings on triangular algebras. Triangular algebras are algebras whose elements can be written in the form of 2 x 2 matrices [special characters omitted]where a ∈ A, ...
• Irreversible k-threshold conversion processes on graphs 

  Wodlinger, Jane (2018-04-30)

  Given a graph G and an initial colouring of its vertices with two colours, say black and white, an irreversible k-threshold conversion process on G is an iterative process in which a white vertex becomes permanently coloured ...
• Particle systems with quasihomogeneous interaction 

  Stoica, Cristina (2018-03-16)

  In this dissertation we analyse from a qualitative standpoint motion in a quasihomogeneous potential field: we offer a complete description of the flow associated with the two-body problem in quasihomogeneous field, obtain ...
• A program evaluation of applications of Mathematics 10 in British Columbia public schools 

  McAskill, Donald Bruce (2018-02-22)

  This is an outcomes based program evaluation which used a nonequivalent control-group design to determine the effectiveness of the implementation of Applications of Mathematics 10 in British Columbia public schools. The ...
• Host contact structure is important for the recurrence of influenza A 

  Jaramillo, Juan M. (2018-01-08)

  An important characteristic of influenza A is its ability to escape host immunity through antigenic drift. A novel influenza A strain that causes a pandemic confers full immunity to infected individuals, yet because of ...
• Mathematical models to investigate the relationship between cross-immunity and replacement of influenza subtypes 

  Asaduzzaman, S M (2018-01-08)

  A pandemic subtype of influenza A sometimes replaces (e.g., in 1918, 1957, 1968) but sometimes coexists (e.g., in 1977) with the previous seasonal subtype. This research aims to determine a condition for replacement or ...
• Is ocean reflectance acquired by ferry passengers robust for science applications? 

  Yang, Yuyan (2017-12-22)

  Monitoring the dynamics of the productivity of ocean water and how it affects fisheries is essential for management. It requires data on proper spatial/temporal scales, which can be provided by operational ocean colour ...
• C*-algebras of sofic shifts 

  Samuel, Jonathan Niall (2017-11-15)

  This Dissertation shows how the theory of C*-algebra of graphs relates to the theory of C*-algebras of sofic shifts. C*-algebras of sofic shifts are generalizations of Cuntz-Krieger algebras [8]. It is shown that if X is ...
• A fast and efficient solver for viscous-plastic sea ice dynamics 

  Seinen, Clint (2017-10-04)

  Sea ice plays a key role in the global climate system. Indeed, through the albedo effect it reflects significant solar radiation away from the oceans, while it also plays a key role in the momentum and heat transfer ...
• A pipeline for differential expression analysis of RNA-seq data and the effect of filter cutoff on performance 

  Robert, Bonnie-Jean (2017-09-01)

  RNA sequencing is a powerful new approach to analyzing differential expression of transcripts between treatments. Many statistical methods are now available to test for differential expression, each one reports results ...
