Under-Ice Fluid Dynamics in Freshwater Lakes: Implications for Ecology in a Changing Climate
(University of Waterloo, 2021-08-24)An abundance of evidence exists to support the notion of annual winter blooms of phytoplankton, particularly diatoms, persistent in the surface waters of freshwater lakes located in temperate and boreal climatic zones. ... -
Universe Beyond Inflation and ΛCDM
(University of Waterloo, 2021-09-09)The current paradigm of universe, $\Lambda CDM$ model with an early phase of inflation, has been quite successful in describing our universe in a simple manner, yet matching well with the observational evidence. This model ... -
Unsteady Free Convection from Elliptic Tubes at Large Grashof Numbers
(University of Waterloo, 2008-09-11)This study solves the problem of unsteady free convection from an inclined heated tube both numerically and analytically. The tube is taken to have an elliptic cross-section having a constant heat flux applied to its ... -
Using numerics to explore the EPRL spinfoam amplitude
(University of Waterloo, 2020-08-25)The use of numerical methods in loop quantum gravity is still relatively untapped. Numerical methods are, however, a useful tool, and offer access to regimes that are as of yet inaccessible by analytical methods. This ... -
Vacuum Energy in Expanding Spacetime and Superoscillation - Induced Resonance
(University of Waterloo, 2008-05-20)This thesis is divided into two parts. The first part is a study of the general problem of vacuum energy or so-called `zero point fluctuations' of a quantum field on expanding spacetimes and the interplay between the ... -
Viewing Trends in Graph Connectivity as Early Warnings of Epidemics and Vaccine Crises
(University of Waterloo, 2020-12-15)When measles was rampant, suffering apparent, and relief desired, the prospect of vaccination was received with open arms by a grateful public. But it worked \emph{too} well, and opinions slowly diverged; scientists saw ... -
“Wait and see” vaccinating behavior during a pandemic: a game theoretic analysis
(Elsevier, 2011-07-26)During the 2009 H1N1 pandemic, many individuals adopted a “wait and see” approach to vaccinating until further information was available on the course of the pandemic and emerging vaccine risks. This behaviour implies two ... -
A walk through quantum noise: a study of error signatures and characterization methods
(University of Waterloo, 2019-09-17)The construction of large scale quantum computing devices might be one of the most exciting and promising endeavors of the 21st century, but it also comes with many challenges. As quantum computers are supplemented with ... -
Wall turbulence response to surface cooling and formation of strongly stable stratified boundary layers
(AIP, 2019-08-20)This paper investigates the processes by which stable boundary layers are formed through strong surface cooling imposed on neutrally stratified wall-bounded turbulence using high-resolution direct numerical simulation at ... -
Wave Refraction Effects in High Intensity Focused Ultrasound
(University of Waterloo, 2019-01-22)High-Intensity Focused Ultrasound (HIFU) is a promising field of research being developed as an alternative to surgery and radiation therapy for the treatment of tumours. Within this field, many current methods of ... -
Well-Posedness of Boundary Control Systems
(Society for Industrial and Applied Mathematics, 2003-01-01)Continuity of the input/output map for boundary control systems is shown through the system transfer function. Our approach transforms the question of continuity of the input/output map of a boundary control system to ... -
What is a field, what is a particle?
(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 ... -
WKB Analysis of Tunnel Coupling in a Simple Model of a Double Quantum Dot
(University of Waterloo, 2008-12-16)A simplified model of a double quantum dot is presented and analyzed, with applications to spin-qubit quantum computation. The ability to trap single electrons in semiconductor nanostructures has led to the proposal of ... -
Zero dynamics for networks of waves
(Elsevier, 2019-05)The zero dynamics of infinite-dimensional systems can be difficult to characterize. The zero dynamics of boundary control systems are particularly problematic. In this paper the zero dynamics of port-Hamiltonian systems ... -
Zero Dynamics for Port-Hamiltonian Systems
(2017-11-19)The zero dynamics of infinite-dimensional systems can be difficult to characterize. The zero dynamics of boundary control systems are particularly problematic. In this paper the zero dynamics of port-Hamiltonian systems ...
