Numerical Simulations of Internal Solitary and Solitary-Like Waves: Wave Interactions and Instabilities
(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 ... -
Numerical Simulations of Reactive Extrusion in Twin Screw Extruders
(University of Waterloo, 2010-01-18)In this work, the peroxide-initiated degradation of polypropylene (PP) in co-rotating intermeshing twin-screw extruders (COITSEs) is analyzed by means of numerical simulations. This reactive extrusion (REX) operation is ... -
Numerical Simulations of Shoaling Internal Solitary Waves of Elevation
(University of Waterloo, 2015-04-13)We present high-resolution, two- and three-dimensional direct numerical simulations of laboratory-scale, fully nonlinear internal solitary waves of elevation shoaling onto and over a small-amplitude shelf. The three-dimensional, ... -
Numerical Simulations of Small-scale and Full-scale Fire Experiments
(University of Waterloo, 2018-06-15)A fundamental part of fire safety engineering is dedicated to the application of numerical fire models. Accurate predictions of real-life fires are needed in scenarios related to fire growth, smoke propagation, occupant ... -
Numerical Simulations of Undrained Granular Media
(University of Waterloo, 2004)The objective of the present study was to develop a fluid flow-coupled distinct element model capable of capturing the undrained behaviour of granular soils by considering fundamental physical mechanisms that involve fluid ... -

Numerical Solutions of Two-factor Hamilton-Jacobi-Bellman Equations in Finance
(University of Waterloo, 2015-12-03)In this thesis, we focus on solving multidimensional HJB equations which are derived from optimal stochastic control problems in the financial market. We develop a fully implicit, unconditionally monotone finite difference ... -
Numerical Solutions to Stochastic Control Problems: When Monte Carlo Simulation Meets Nonparametric Regression
(University of Waterloo, 2019-07-30)The theme of this thesis is to develop theoretically sound as well as numerically efficient Least Squares Monte Carlo (LSMC) methods for solving discrete-time stochastic control problems motivated by insurance and finance ... -
Numerical Stability in Linear Programming and Semidefinite Programming
(University of Waterloo, 2006)We study numerical stability for interior-point methods applied to Linear Programming, LP, and Semidefinite Programming, SDP. We analyze the difficulties inherent in current methods and present robust algorithms. ... -
Numerical studies of transport and spin-orbit exchange in InAs nanowires
(University of Waterloo, 2013-01-11)High spin-orbit coupling and low effective mass of electrons in InAs nanowires makes it an attractive material for studying quantum physics in mesoscopic and nanoscale quantum devices. We first study the transport properties ... -
Numerical Study of a Viscoelastic Model for Hydrocephalus
(University of Waterloo, 2006)Hydrocephalus is a clinical conditon where the brain tissue is deformed by the expanding ventricules. In this thesis, the mechanical deformation of a hydrocephalic brain is studied using a biomechanical model, where the ... -
Numerical Study on Single Flowing Liquid and Supercritical CO2 Drop in Microchannel: Thin Film, Flow Fields, and Interfacial Profile
(MDPI, 2018-06-01)Taylor segments, as a common feature in two- or multi-phase microflows, are a strong flow pattern candidate for applications when enhanced heat or mass transfer is particularly considered. A thin film that separates these ... -
Numerosity and Cognitive Complexity of a Medium as Moderators of Medium Effect on Effort
(University of Waterloo, 2010-09-30)As a part of loyalty programs in marketing or as incentive plans in companies, mediums have attracted considerable interest from marketing and organizational behavior researchers. Previous studies focused mainly on the ... -
Nuna-Regionalism: A Vision of Iqaluit Regionalism
(University of Waterloo, 2013-02-22)The recent demographic shift, sparked by a combination of political and environmental forces, towards urbanization in the Canadian Arctic has uprooted a tie to the land that largely defines Inuit cultural identity. The ... -
