Operator Spaces and Ideals in Fourier Algebras
(University of Waterloo, 2008-08-11)In this thesis we study ideals in the Fourier algebra, A(G), of a locally compact group G. For a locally compact abelian group G, necessary conditions for a closed ideal in A(G) to be weakly complemented are given, ... -
Operator Theoretic Methods in Nevanlinna-Pick Interpolation
(University of Waterloo, 2009-03-31)This Master's thesis will develops a modern approach to complex interpolation problems studied by Carath\'{e}odory, Nevanlinna, Pick, and Schur in the early $20^{th}$ century. The fundamental problem to solve is as follows: ... -
OPERATORS WHICH ARE POLYNOMIALLY ISOMETRIC TO A NORMAL OPERATOR
(American Mathematical Society, 2020-01-15)Let H be a complex, separable Hilbert space and B(H) denote the algebra of all bounded linear operators acting on H. Given a unitarily-invariant norm k · ku on B(H) and two linear operators A and B in B(H), we shall say ... -
Opportunistic Spectrum Utilization for Vehicular Communication Networks
(University of Waterloo, 2016-06-21)Recently, vehicular networks (VANETs), has become the key technology of the next-generation intelligent transportation systems (ITS). By incorporating wireless communication and networking capabilities into automobiles, ... -
The Opportunities and Challenges of Aggregate Site Rehabilitation in Southern Ontario. An Evaluation of the Rehabilitation Process from 1992-2011
(University of Waterloo, 2013-09-27)Aggregate extraction has been identified as one of the most contentious land-uses in Southern Ontario. The siting or expansion of aggregate operations is often met with vehement debate from concerned members of the public, ... -
Opportunities for Redistribution and Area Planning in Parks A Case Study at Bruce Peninsula National Park
(University of Waterloo, 2015-05-12)Some national parks in Canada are experiencing growing visitor numbers and changes in visitor demographics. Bruce Peninsula National Park, located in Tobermory Ontario is one such park experiencing this phenomenon. Increased ... -
Opportunities for Redress: Re-imagining Relations, Restoration, and Leisure for Uniformed Bodies serving as First Responders
(University of Waterloo, 2023-03-17)In times of distress, uniformed first responders (UFRs) are the first formal line of care on scene and are responsible for providing care. Due to the obligations required of UFRs, they are considered to be at higher risk ... -
Opportunity in Absence: Activating Vacant Space in The Temporary City
(University of Waterloo, 2015-09-24)The vacant buildings in Cambridge await new uses as traditional commercial activity has shifted to the sprawl that defines the landscape between the city’s historic cores. Downtown businesses have been replaced by big-box ... -
Opposing effects of cationic antimicrobial peptides and divalent cations on bacterial lipopolysaccharides
(American Physical Society, 2017-10-09)The permeability of the bacterial outer membrane, enclosing Gram-negative bacteria, depends on the interactions of the outer, lipopolysaccharide (LPS) layer, with surrounding ions and molecules. We present a coarse-grained ... -
Opposition-Based Differential Evolution
(University of Waterloo, 2007-05-07)Evolutionary algorithms (EAs) are well-established techniques to approach those problems which for the classical optimization methods are difficult to solve. Tackling problems with mixed-type of variables, many local optima, ... -
Oppositional Reinforcement Learning with Applications
(University of Waterloo, 2008-09-25)Machine intelligence techniques contribute to solving real-world problems. Reinforcement learning (RL) is one of the machine intelligence techniques with several characteristics that make it suitable for the applications, ... -
OppropBERT: An Extensible Graph Neural Network and BERT-style Reinforcement Learning-based Type Inference System
(University of Waterloo, 2022-12-20)Built-in type systems for statically-typed programming languages (e.g., Java) can only prevent rudimentary and domain-specific errors at compile time. They do not check for type errors in other domains, e.g., to prevent ... -
Optical aberrations and cone photoreceptor sampling during normal emmetropization and emmetropization to imposed defocus
(University of Waterloo, 2018-04-23)The eye grows in a coordinated fashion during normal emmetropization which results in an image close to being in focus on the retina for distance vision. Myopia results from the failure of normal emmetropization. Myopia ... -
Optical and Microwave Beamforming for Phased Array Antennas
(University of Waterloo, 2009-01-19)Phased array antenna has been used for a variety of military and civil applications, over the past five decades. Being structurally conformal and flexible, phased array antenna is highly suitable for mobile applications. ... -
Optical Biosensing Using Localized Surface Plasmon Resonance of Gold Nanoparticles
(University of Waterloo, 2011-05-25)This thesis describes some experiments developed to probe the fundamental aspects of the interfacial behaviour of proteins. The contents of this thesis can be broadly divided into two parts. In the first part, we ... -
Optical Changes during Normal Emmetropization, Lens-induced Myopia and its Recovery in the Young Chick Eye
(University of Waterloo, 2015-01-20)In human eyes, the at-birth hyperopoic defocus gradually decreases to mild hyperopia or emmetropia at around age 6. Studies on refractive development suggest somewhat complex mechanisms at work between eye power and length. ... -
Optical Coherence Tomography Image Analysis of Corneal Tissue
(University of Waterloo, 2012-01-23)Because of the ubiquitous use of contact lenses, there is considerable interest in better understanding the anatomy of the cornea, the part of the eye in contact with an exterior lens. The recent technology developments ... -
Optical Design for an Open Access Trapped Ion Quantum Processor
(University of Waterloo, 2021-08-31)The future of quantum information is scaling to a ever larger number of qubits. Doing so will require advances in the approach for all aspects of current experimental systems. The QuantumION project is a large step in this ... -
