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 ... -
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 ... -
Philosophy in Pieces: The Aphorisms of Nietzsche's Human, All Too Human and Wittgenstein's Philosophical Investigations
(University of Waterloo, 2012-09-28)This thesis considers the philosophical importance of the literary form of two aphoristic works of philosophy: Nietzsche’s Human, All Too Human and Wittgenstein’s Philosophical Investigations. Though both these German-speaking ... -
The Philosophy of Bioinformatics
(University of Waterloo, 2007-01-22)The development of bioinformatics as an influential biological field should interest philosophers of biology and philosophers of science in general. Bioinformatics contributes significantly to the development of biological ... -
Phosphor Coated UV-Responsive CCD Image Sensors
(University of Waterloo, 2002)Typical CCD image sensors are not sensitive to Ultra-Violet (UV) radiation, because the UV photons have a penetration depth of 2nm in the ~1µm thick polysilicon gate material. An inorganic phosphor coating was ... -
Phosphoric Acid Doped Polybenzimidazole-Based Membrane Electrode Assembly for a Highly Sensitive and Selective Acetone Gas Sensor
(University of Waterloo, 2018-08-03)The increase in demand for small, inexpensive and portable gas sensors, which are sensitive and reliable, have generated much of the research interest toward solid oxide metal-based acetone gas sensors. However, despite ... -
Phosphorus and Nitrogen Cycling in the Mediterranean Sea: Circulation, biogeochemistry and anthropogenic forcing
(University of Waterloo, 2017-04-28)The Mediterranean Sea (MS) is an oligotrophic marine basin despite being semi-enclosed with unusually low inorganic phosphorus (P) and nitrogen (N) concentrations, and high nitrate (NO₃):phosphate (PO₄) ratios comparative ... -
