Learning Quantum States Without Entangled Measurements
(University of Waterloo, 2021-10-22)How many samples of a quantum state are required to learn a complete description of it? As we will see in this thesis, the fine-grained answer depends on the measurements available to the learner, but in general it is at ... -
Understanding Mode and Modality Transfer in Unistroke Gesture Input
(University of Waterloo, 2021-10-22)Unistroke gestures are an attractive input method with an extensive research history, but one challenge with their usage is that the gestures are not always self-revealing. To obtain expertise with these gestures, interaction ... -
Fingerprint-based indoor positioning and intensity classification using an improved machine learning framework
(University of Waterloo, 2021-10-21)Covid-19 has changed the world in terms of business, public, and many other fields. Millions of livelihoods have been affected by the pandemic. Amidst the upheaval, work from home and restrictions on indoor gatherings have ... -
Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
A Scalable Recoverable Skip List for Persistent Memory on NUMA Machines
(University of Waterloo, 2021-10-20)Interest in recoverable, persistent-memory-resident (PMEM-resident) data structures is growing as availability of Intel Optane Data Center Persistent Memory increases. An interesting use case for in-memory, recoverable ... -
Constitutive Behaviour and Formability of Pre-aged AA7075 Sheet in a Warm Forming Process
(University of Waterloo, 2021-10-19)Warm constitutive and formability characterization of a high strength aluminum alloy (AA7075) was performed for a range of pre-aged (i.e. under-aged) tempers, strain rates and temperatures. The pre-aging processes were ... -
Measuring and modelling soil erosion in agricultural systems: Evaluating the application of UAVs and SfM-MVS for soil erosion research
(University of Waterloo, 2021-10-19)Soil erosion in agricultural systems is a pressing issue for agricultural sustainability. Accelerated rates of soil erosion from conventional agricultural practices continues to outpace the rate of natural soil regeneration, ... -
A Quantitative and Qualitative Empirical Evaluation of a Test Refactoring Tool
(University of Waterloo, 2021-10-18)Reducing the gap between what practitioners want vs. what researchers assume they want is one of the vital challenges in software projects. When it comes to software tools, many people develop tools, but only some tools ... -
Reducing the Latency of Dependent Operations in Large-Scale Geo-Distributed Systems
(University of Waterloo, 2021-10-14)Many applications rely on large-scale distributed systems for data management and computation. These distributed systems are complex and built from different networked services. Dependencies between these services can ... -
Identifying Prioritized Areas for Grassed Waterways Implementation
(University of Waterloo, 2021-10-14)Soil erosion remains a primary challenge in the 21st century threatening fresh water and cropland that supports more than 95% of global food production. It is of significance to plan for and prevent soil erosion in its ... -
Separation of Phenols and Aniline from Water Streams using Poly(ether-block-amide) Membranes
(University of Waterloo, 2021-10-14)Phenols and aniline are aromatic compounds in which a hydroxyl group and amine group are attached to the benzene ring, respectively. Both are common organic pollutants in a wide range of effluents from such industries as ... -
Flags and Error Weight Parities: A Development of Fault-tolerant Quantum Computation with Few Ancillas
(University of Waterloo, 2021-10-13)In quantum computation, errors in a quantum circuit arising from its interaction with the environment is one of the biggest obstacles to building large-scale quantum computers. One way to deal with such errors is using ... -
Powder-fed Laser Directed Energy Deposition of Near-β Titanium Alloy: A Comprehensive Analytical and Experimental Analysis
(University of Waterloo, 2021-10-12)Laser directed energy deposition through powder feeding (LDED-PF), a class of metal additive manufacturing (AM), is a promising technique that enables the repair and refurbishment of metallic components with a variety of ... -
Detection and Prediction of Freezing of Gait in Parkinson’s Disease using Wearable Sensors and Machine Learning
(University of Waterloo, 2021-10-12)Freezing of gait (FOG), is a brief episodic absence of forward body progression despite the intention to walk. Appearing mostly in mid-late stage Parkinson’s disease (PD), freezing manifests as a sudden loss of lower-limb ... -
Local Structure for Vertex-Minors
(University of Waterloo, 2021-10-12)This thesis is about a conjecture of Geelen on the structure of graphs with a forbidden vertex-minor; the conjecture is like the Graph Minors Structure Theorem of Robertson and Seymour but for vertex-minors instead of ... -
Silver Nanowire-enhanced Microflake Electrically Conductive Adhesives for Flexible Hybrid Electronics
(University of Waterloo, 2021-10-08)Flexible hybrid electronics combine the power and performance of conventional integrated circuits with the large area, lower cost, and mechanical flexibility of printed, flexible electronics. To mount rigid, discrete ... -
The Rebirth of Rape: Tracing Ovidian Rape Motifs with Respect to Bernini's Pluto and Persephone as a Piece of Classical Reception
(University of Waterloo, 2021-10-08)Rape, as it is understood in a modern context, is approached with a completely different perspective than that of an ancient, and even a post-Renaissance, audience. With the contributing factors of cultural, historical, ... -
Spillover gentrification? Mid-sized cities within commuter sheds of global cities
