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 ... -
Constitutive Modelling of Creep in a Long Fiber Random Glass Mat Thermoplastic Composite
(University of Waterloo, 2009-01-16)Random Glass Mat Thermoplastic (GMT) composites are increasingly being used by the automotive industry for manufacturing semi-structural components. The polypropylene based materials are characterized by superior strength, ... -
Constrained Nonnegative Matrix Factorization with Applications to Music Transcription
(University of Waterloo, 2014-08-15)In this work we explore using nonnegative matrix factorization (NMF) for music transcription, as well as several other applications. NMF is an unsupervised learning method capable of finding a parts-based additive model ... -
Constrained Rationality: Formal Value-Driven Enterprise Knowledge Management Modelling and Analysis Framework for Strategic Business, Technology and Public Policy Decision Making & Conflict Resolution
(University of Waterloo, 2011-05-20)The complexity of the strategic decision making environments, in which busi- nesses and governments live in, makes such decisions more and more difficult to make. People and organizations with access to the best known ... -
Constrained Shortest Paths in Terrains and Graphs
(University of Waterloo, 2009-10-28)Finding a shortest path is one of the most well-studied optimization problems. In this thesis we focus on shortest paths in geometric and graph theoretic settings subject to different feasibility constraints that arise in ... -
Constraining sources of atmospheric trace constituents with Lagrangian particle dispersion modeling
(University of Waterloo, 2013-06-19)This manuscript based thesis examines and advances methods for constraining sources of atmospheric trace constituents with a Lagrangian particle dispersion model. The method of Bayesian inversion is demonstrated, and a new ... -
Constraining the Properties of Sagittarius A* with the Event Horizon Telescope
(University of Waterloo, 2015-10-01)Sagittarius A* (Sgr A*) is a primary target for testing strong gravity, jet formation and black hole accretion for the the Event Horizon Telescope (EHT). Motivated by continued improvements of the observations from the ... -
Constraint Programming Techniques for Optimal Instruction Scheduling
(University of Waterloo, 2008-04-21)Modern processors have multiple pipelined functional units and can issue more than one instruction per clock cycle. This puts great pressure on the instruction scheduling phase in a compiler to expose maximum instruction ... -
Constraint-Guided Machine Learning for Solving Optimal Power Flow Problem
(University of Waterloo, 2022-08-31)Due to the nonlinear and non-convex attributes of the optimization problems in power systems such as Optimal Power Flow (OPF), traditional iterative optimization algorithms require significant amount of time to converge ... -
Constructing an External Cavity Diode Laser for the Probing of Rydberg Excitons in Cu2O
(University of Waterloo, 2021-10-05)Cuprous oxide (Cu2O) is a direct bandgap semiconductor that presents a promising platform for the implementation of a solid state quantum simulator. This promise is in part due to the presence of excitons in the material ... -
Constructing China’s National Food Security: Power, Grain Seed Markets, and the Global Political Economy
(University of Waterloo, 2019-07-19)What is China’s place in the global food system? This thesis provides an analytical lens to explain the factors behind the structure of China’s national seed industry and recent global agribusiness expansion. Scholars of ... -
Constructing Cospectral and Comatching Graphs
(University of Waterloo, 2019-07-18)The matching polynomial is a graph polynomial that does not only have interesting mathematical properties, but also possesses meaningful applications in physics and chemistry. For a simple graph, the matching polynomial ... -
Constructing Crime: Understanding the Roles, Functions and Claims-Making Activities of Media Relations Officers in Ontario
(University of Waterloo, 2019-02-22)Despite a growing body of prior research, little attention has been paid to media relations officers (MROs) and how media releases are constructed for the public. This research begins to address this gap by examining the ... -
Constructing Exact Correlators In N=4 SYM Using Integrability
(University of Waterloo, 2019-08-09)This thesis is devoted to the study of correlation functions in N = 4 superconformal Yang- Mills theory. We focus on a class of four point functions for which we achieve formal results at finite coupling and explicit ... -
Constructing multilingual selves. Subjective perspectives on learning and living with German as a "heritage" language in Canada
(University of Waterloo, 2018-12-14)Based on the perception that language students who have a family background in the target language differ from ‘typical’ foreign language learners in important ways, the phenomenon of what has been termed "heritage language ... -
Constructing Our Environments: A Material Comparison
(University of Waterloo, 2014-08-12)Our built environment is constantly adapting to changing factors: technology, the state of the economy, material resource availability, and, in turn, environmental conditions. The latter has gained notable importance in ... -
Construction and Characterization of a Fine-Tuned Lytic Phage Display System
(University of Waterloo, 2014-08-15)Bacteriophage (phage) Lambda (λ) has played a key historic role in driving our current understanding of molecular genetics. The lytic nature of this bacterial virus along with the conformation of its wild-type capsid protein ... -
Construction and characterization of a hybrid bacteriophage gene delivery platform
(University of Waterloo, 2022-04-26)Bacteriophages, viruses that specifically infect bacteria, may be considered as structurally simplistic protein-based vehicles for ferrying nucleic acid cargo. Since phages cannot infect nor replicate within human cells, ... -
