Constituting Restorative Justice: A Case Study Exploring Volunteers’ Experiences of Meaning
(University of Waterloo, 2018-08-31)Restorative Justice (RJ), a model for responding to crime that focuses on addressing harm and restoring the relationships between victim, offender, and community, has gained legitimacy as an effective alternative to lengthy ... -
Constitutive and Fracture Characterization and Modelling of Monolithic and Tailor-Welded Blanks of Press-Hardening Steels
(University of Waterloo, 2021-04-21)This study investigates the constitutive (flow) and fracture response of two automotive-grade press-hardening steels, Usibor® 1500-AS and Ductibor® 500-AS, as well as their tailor-welded blanks (TWBs), for a range of ... -
Constitutive and Fracture Characterization of an Anisotropic and Asymmetric Alloy Sheet
(University of Waterloo, 2018-02-14)Magnesium alloys can offer significant weight reduction over conventional steel or aluminum alloys. Specifically, rare-earth alloyed magnesium sheets have the potential to be used as light-weight structural alloys since ... -
Constitutive and Fracture Characterization of High Strength Aluminum Alloys at Low and Elevated Strain Rates
(University of Waterloo, 2022-05-27)The present research investigates the constitutive and fracture behavior of three high strength automotive aluminum sheet alloys, AA6013-T6, AA7075-T6, and AA7xxx-T6 under quasi-static and elevated strain rate conditions. ... -
Constitutive and Friction Characterization and Simulation of AA7075 Aluminum Alloy Sheet under Die Quenching Conditions
(University of Waterloo, 2022-10-31)This thesis investigates the die quench forming of AA7075 aluminum alloy sheet, including the constitutive and friction behaviour at elevated temperatures. Experiments examining characterization of friction behaviour and ... -
Constitutive Behavior of Aluminum Alloy Sheet At High Strain Rates
(University of Waterloo, 2005)In this work, three aluminum sheet alloys, AA5754, AA5182 and AA6111, which are prime candidates for replacing mild steel in automobile structures, are tested in tension at quasi-static and high strain rates. <br /><br ... -
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 characterization of a rare-earth magnesium alloy sheet (ZEK100-O) in shear loading: Studies of anisotropy and rate sensitivity
(Elsevier, 2017-08-01)Rare-earth magnesium alloys such as ZEK100-O offer improved ductility over other conventional magnesium alloys at room temperature; however, they exhibit significant anisotropy and complex yield behaviour. In this work, a ... -
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 ... -
Constrained-CNN losses for weakly supervised segmentation
(Elsevier, 2019-05)Weakly-supervised learning based on, e.g., partially labelled images or image-tags, is currently attracting significant attention in CNN segmentation as it can mitigate the need for full and laborious pixel/voxel annotations. ... -
