Tuktu Past, Present, and Future: State of Torngat Mountains Caribou and their Forage in a Changing Environment
(University of Waterloo, 2022-05-20)Caribou (Rangifer tarandus) populations are in decline across Canada, making this charismatic species a major conservation concern. For Inuit of Northern Labrador and Quebec, caribou are a cultural keystone species with ... -
THE TULU KAPI GOLD DEPOSIT OF THE WESTERN ETHIOPIAN SHIELD: STRUCTURAL FRAMEWORK, U-PB ZIRCON GEOCHRONOLOGY AND PARAGENESIS
(University of Waterloo, 2019-04-10)Gold production dates back millennia in the Arabian Nubian Shield. Most of the mined deposits are in the northern portions of the shield, with little know about its southern extent. Tulu Kapi is a rare example of a gold ... -
Tunable Band Pass Filters for Communication Systems
(University of Waterloo, 2021-05-08)The ever-increasing demand for high communication data rate and high-quality multi-media services; over past few decades, has ignited new avenues in radio architectures. Frequency reconfigurable (or frequency agile) ... -
Tunable Coupler in Superconducting Circuits and Impedance Engineering for Josephson Parametric Amplifier
(University of Waterloo, 2020-09-04)In this thesis, we study two topics on superconducting circuits. The first topic is the tunable coupler for resonators. This coupler is implemented with a superconducting circuit coupling with resonators in the dispersive ... -
Tunable Filters and RF MEMS Variable Capacitors with Closed Loop Control
(University of Waterloo, 2012-01-23)Multi-band and multi-mode radios are becoming prevalent and necessary in order to provide optimal data rates across a network with a diverse and spotty landscape of coverage areas (3G, HSPA, LTE, etc.). As the number of ... -
Tunable Permittivity Sensors
(University of Waterloo, 2021-09-02)This thesis presents a novel electric permittivity sensor based on Bleustein- Gulyaev (BG) waves; waves that propagate along the surface of shear-poled piezoelectric materials. BG waves couple electromagnetic and acoustic ... -
Tunable Reflectarrays and Metasurfaces
(University of Waterloo, 2022-05-19)Fifth-generation (5G) wireless communication networks have been rapidly expanding in recent years. However, due to the higher frequency bands used in 5G applications compared with previous generations, it is more difficult ... -
Tunable Superconducting Microwave Filters
(University of Waterloo, 2010-08-20)Adaptive microwave systems can benefit from the use of low loss tunable microwave filters. Realizing these tunable filters that show low loss characteristics can be very challenging. The proper materials, tuning elements, ... -
Tunable three-body interactions between superconducting flux qubits for quantum annealing
(University of Waterloo, 2019-09-03)The field of quantum information has been a fast growing field of research in the last few decades. The reason for this development is the potentially immense power of quantum computers, capable of solving hard problems ... -
Tunable Two-Color Ultrafast Yb:Fiber Chirped Pulse Amplifier: Modeling, Experiment, and Application in Tunable Short-Pulse Mid-Infrared Generation
(University of Waterloo, 2013-10-04)In this thesis, I have developed a tunable two-color two-stage ultrafast Yb:fiber chirped pulse amplifier for the generation of short-pulse mid-infrared (MIR) radiation in the long-wavelength side of the "molecular ... -
Tuneable Hybrid and Multimode Squeezed States of Light
(University of Waterloo, 2020-09-03)Gaussian quantum states of light have many applications in quantum technologies. Two of the most widely used Gaussian quantum states of light are the single- and two-mode squeezed states. In this thesis, we propose the ... -
Tuning and Predicting Consistency in Distributed Storage Systems
(University of Waterloo, 2017-09-27)Distributed storage systems are constrained by the finite speed of propagation of information. The CAP (which stands for consistency, availability, and partition tolerance) theorem states that in the presence of network ... -
Tuning Cation and Anion Redox Chemistry in Transition Metal Oxide Positive Electrode Materials for Lithium and Sodium-Ion Batteries
(University of Waterloo, 2021-03-31)The surging demand for electrified transportation (both ground and air), robots, and other battery-powered devices has driven the development of electrochemical energy storage systems that can provide high gravimetric/volumetric ... -
Tuning Monuments
(University of Waterloo, 2020-05-25)This thesis examines the development of historically inaccurate monuments that censor and sanitize reality by questioning their ongoing legacies by using a derivative of counter monument culture. Tuning Monuments seeks to ... -
Tunnel Ionization in Strong Fields in atoms and molecules and its applications
(University of Waterloo, 2011-04-26)We look at the theory of ionization of atoms and molecules in the presence of a strong laser field. The history of ionization of atoms is reviewed and the methods used to calculate the ionization rates are examined in ... -
