Phase Relations, Reaction Sequences and Petrochronology
(Mineralogical Society of America, 2017-02-01)Phase equilibria modelling has played a key role in enhancing our understanding of metamorphic processes. An important breakthrough in the last three decades has been the ability to construct phase diagrams by integrating ... -
Phase Retrieval Methods for Polychromatic Propagation-Based Phase-Contrast X-ray Imaging
(University of Waterloo, 2019-07-18)X-ray imaging, based on conventional attenuation methods, is employed in various industrial, medical and scientific imaging application. Phase-contrast X-ray imaging is an emerging modality that has shown promise to image ... -
Phase Shifter and LNA Design for Satellite Communication
(University of Waterloo, 2018-06-20)Phased arrays are being used in satellite communication systems in order to provide wireless data to mobile vehicles, ships and even aircrafts. This thesis focuses on the design of phase shifter, which is designed for the ... -
Phase-Locked Loop Stability Based on Stochastic Bounds
(Springer, 2015-08-11)In this paper we study the stability of a phase-locked loop (PLL) in the presence of noise. We represent the noise as Brownian motion and model the circuit as a nonlinear stochastic differential equation, with the noise ... -
A Phase-shifted Fiber Bragg Grating Based Humidity Sensor
(University of Waterloo, 2013-08-30)A humidity fiber optic sensor based on phase-shifted (PS) Fiber Bragg gratings (FBG) is demonstrated. Compared to the standard FBG sensors, the peak of the PS-FBG slips into 2 narrow peaks and forms a sharp dip in the ... -
Phased-Array Antenna-in-Package Technology for Emerging Millimeter Wave Applications
(University of Waterloo, 2022-03-22)The ever-increasing data rates for wireless technologies (e.g., satellite communications, fifth generation (5G) wireless communications, and automotive radars) has directed the interests towards millimeter wave (mm-Wave) ... -
A phenomenological investigation of spirituality in outdoor recreation experiences
(University of Waterloo, 2020-05-22)There exists a rich history of people describing meaningful moments during outdoor recreation as spiritual experiences. These involve connecting to something bigger than yourself, and recognizing your place in a larger ... -
A PHENOMENOLOGICAL MODEL OF SHAPE MEMORY ALLOYS INCLUDING TIME-VARYING STRESS
(University of Waterloo, 2007-08-22)Shape memory alloys (SMAs) are metallic materials, which have two main stable crystalline phases: austenite, a high temperature phase and martensite, a low temperature phase. Austenite and martensite each have unique ... -
Phenomenological Modeling of Sheet Moulding Compound Composites Under Quasi-Static Three-Point Bending
(University of Waterloo, 2018-06-19)A phenomenological model is implemented to model the behaviour of a glass fiber reinforced sheet moulding composite material. Previous characterization of SMC composites, which included the tensile, compressive, in-plane ... -
The Phenomenological Origins of Property
(University of Waterloo, 2018-09-26)This thesis delineates the phenomenological basis of ownership and property. The phenomenological theory of property has three main elements: the minimal self, the relationship between the sense of agency and the sense of ... -
The Phenotype of Tear Neutrophils and Their Role in Ocular Homeostasis and Inflammation
(University of Waterloo, 2023-07-31)Introduction: Neutrophils (polymorphonuclear neutrophils, PMNs) are part of the innate immune system with potent killing mechanisms against pathogens. Although the anterior segment of the eye has a unique characteristic, ... -
Phenotypic Characterization of the Male Tafazzin-Knockout Mouse Model of Barth Syndrome at 3-, 6-, and 12-Months of Age
(University of Waterloo, 2022-05-18)Barth Syndrome (BTHS) is a devastating disorder caused by mutations in the gene encoding for Tafazzin (TAZ), a key enzyme involved in the biosynthesis of the phospholipid cardiolipin, which is vital for maintaining the ... -
Phenotyping Risk Profiles of Substance Use and Exploring the Dynamic Transitions in Use Patterns: Machine Learning Models using the COMPASS Data
(University of Waterloo, 2021-10-01)Background Polysubstance use is on the rise among Canadian youth. Examining risk profiles and understanding how the transition occurs in use patterns can inform the design and implementation of polysubstance risk reduction ... -
Philanthropic Gifting in Tourism: A Study of Guardalavaca and Varadero, Cuba
(University of Waterloo, 2011-06-14)Incorporating philanthropy into tourism, through practices such as volunteer tourism and non-governmental organization (NGO) work, is becoming an increasingly popular way for tourists to aid people of developing nations ... -
THE PHILOSOPHICAL SIGNIFICANCE OF QUINE'S D-THESIS
(University of Waterloo, 2016-02-02)The philosophical significance of Quine's D-thesis is considered. The D-thesis - "Any statement can be held true come what may, if we make drastic enough adjustments elsewhere in the system? (W.V.0. Quine, From a Logical ... -
