On-Site Sampling and Determination of Aliphatic Amines in Industrial Waste Water using SPME
(University of Waterloo, 2012-01-06)In any oil production company, one of the problems that is faced on a daily basis and which sometimes hinders the operation is corrosion. In the presence of dissolved oxygen in the water inside any vessel, tank, or pipeline, ... -
One-dimensional Nanostructures of Hafnium Oxides: Fabrication with and without Ti/Fe Doping, and Magnetic Properties
(University of Waterloo, 2022-01-10)Since the discovery of giant magnetoresistance (GMR) in the late 1980s, which marked the emergence of spintronic technology, the integration of conventional semiconductor-based electronics with spintronics has always been ... -
Onion Root Anatomy and the Uptake of Sulphate and Phosphate Ions
(University of Waterloo, 2007-06-12)Ions in the soil solution traverse many layers (epidermis, exodermis, central cortex, and endodermis) within the root to reach the stele. The endodermis is present in almost all vascular plants while the exodermis is found ... -
Open Port Probe Sampling Interface for the Direct Coupling of Biocompatible Solid-Phase Microextraction to Atmospheric Pressure Ionization Mass Spectrometry
(American Chemical Society, 2017-04-04)In recent years, the direct coupling of solid phase microextraction (SPME) and mass spectrometry (MS) has shown its great potential to improve limits of quantitation, accelerate analysis throughput, and diminish potential ... -
Operational Approaches to Quantum Correlations and Particle Creation in Field Theory
(University of Waterloo, 2015-05-22)In this thesis we examine a variety of question regarding several quantum information-theoretic concepts as they manifest in the context of relativistic quantum fields. In particular, we study the qualitative and quantitative ... -
An Operational Road towards Understanding Causal Indefiniteness within Post-Quantum Theories
(University of Waterloo, 2022-01-07)A theory, whatever it does, must correlate data. We commit ourselves to operational methodology, as a means towards studying the space of Generalised Probability Theories that are compatible with Indefinite Causality. Such ... -
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 ... -
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 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 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 ... -
Optical Fiber Sensors for Temperature and Strain Measurement
(University of Waterloo, 2010-12-09)Optical fiber sensors have already been developed from the experimental stage to practical applications in the past 20 years. There is no doubt that this technology can bring a wealth of applications, ranging from sensors ... -
Optical pulse compression of first anti-Stokes order in the multi-frequency Raman generation with the presence of red shifted shoulder
(University of Waterloo, 2018-09-11)Multi-frequency Raman generation (MRG) is a nonlinear technique to generate intense trains of single-femtosecond pulses. The broad spectrum of different Raman orders which is spread from near-infrared (near-IR) to UV can ... -
Optical Pulse Shaping For Chirped Pulse Interferometry And Bio-Imaging
(University of Waterloo, 2011-09-02)Biomedical imaging requires high resolution to see the fine features of a sample and fast acquisition to observe live cells that move. Optical coherence tomography (OCT) is a powerful technique which uses optical ... -
Optical Quantum Communication & Cryptography with Temporarily Trusted Parties
(University of Waterloo, 2019-09-19)The work in this thesis can be divided into three parts. The first two parts deal with optical quantum communication protocols and the third part deals with quantum cryptography. The first part of the thesis is a step ... -
Optical Resonators Integrated into a Hollow Core Photonic Crystal Fiber for Enhanced Light-Matter Interactions
(University of Waterloo, 2019-08-29)The focus of this thesis is to investigate and fabricate a platform that can facilitate the enhancement of light-matter interactions. By tightly confining the photons and atoms to the same region of space, the probability ... -
Optics, Loss and Gravity
(University of Waterloo, 2021-01-13)We look at some ideas that can be found from making connections among optics, non-Hermitian dynamics and gravity. Using nonlinear optics, we demonstrate how loss can be used to make brighter sources of thermal light. Also, ... -
An optimal framework of investment strategy in brownfields redevelopment by integrating site-specific hydrogeological and financial uncertainties
(University of Waterloo, 2009-07-28)Brownfields redevelopment has been encouraged by governments or the real estate market because of economic, social and environmental benefits. However, uncertainties in contaminated land redevelopment may cause massive ... -
Optimal sampling methods for modelling the occupancy of Arctic grayling (Thymallus arcticus) in the Canadian Barrenlands
(Canadian Science Publishing, 2017)In occupancy models, imperfect detectability of animals is usually corrected for by using temporally-repeated surveys to estimate probability of detection. Substituting spatial replicates for temporal replicates could be ... -
