Voltage Sag Ride-Through and Harmonics Mitigation for Adjustable Speed Drives using Dual-Functional Hardware
(University of Waterloo, 2006)Great portion of today's industry are <em>Adjustable Speed Drives</em> (<em>ASD's</em>) operated in order to fulfill certain processes. When these processes are critical ones or sensitive to voltage disturbances, that ... -
Voltage Stability Analysis with High Distributed Generation (DG) Penetration
(University of Waterloo, 2012-08-14)Interest in Distributed Generation (DG) in power system networks has been growing rapidly. This increase can be explained by factors such as environmental concerns, the restructuring of electricity businesses, and the ... -
Volume Changes during Fracture Injection of Biosolids
(University of Waterloo, 2007-05-22)The term biosolids refers to the nutrient-rich organic materials resulting from the treatment of domestic sewage at a wastewater treatment facility. It is a widely acceptable term for sewage sludge that has been treated ... -
Volume Visualisation Via Variable-Detail Non-Photorealistic Illustration
(University of Waterloo, 2002)The rapid proliferation of 3D volume data, including MRI and CT scans, is prompting the search within computer graphics for more effective volume visualisation techniques. Partially because of the traditional association ... -
A Volumetric Contact Model for Planetary Rover Wheel/Soil Interaction
(University of Waterloo, 2013-01-11)The main objective of this research is the development of a volumetric wheel-soil ground contact model that is suitable for mobile robotics applications with a focus on efficient simulations of planetary rover wheels ... -
Volumetric Weak Supervision for Semantic Segmentation
(University of Waterloo, 2022-05-24)Semantic segmentation is a popular task in computer vision. Fully supervised methods are data hungry, they require pixel precise annotations for thousands of images. To reduce user annotation efforts, weak supervision for ... -
The Voluntary Adoption of Green Electricity by Ontario-Based Businesses
(University of Waterloo, 2005)This paper explores the contextual factors that promote and inhibit firms? motivations to adopt a voluntary environmental initiative that is good for the environment but does not provide a clear competitive or legitimating ... -
Voluntary Simplicity as a Value Orientation in the Lifestyle, Leisure, Well-being Relationship
(University of Waterloo, 2002)Leisure typically has been regarded as a positive component in people's lives, and evidence points to its central rather than peripheral role in lifestyle. Further, studies of leisure suggest it is conducive to psychological ... -
Volunteer Participation in Ecological Restoration: Motivations, Organizations, and Conviviality
(University of Waterloo, 2024-02-28)The state of ecosystems worldwide are increasingly dire. Ecological restoration is a practice that has the potential to remedy ecosystem degradation. Engaging people in ecological restoration can help ensure project success, ... -
Volunteer Tourism: An Exploration of Socially Responsible Tourism Practices
(University of Waterloo, 2016-08-25)This study explored the practices of commercial volunteer tourism operators in order to determine their perspectives on the role certification may play as a strategy for socially responsible volunteer tourism. It was ... -
The Volunteering Self: Ethnographic Reflections on “The Field”
(University of Waterloo, 2010-04-28)This thesis explores the author’s experience of fieldwork in Western Ghana while volunteering to promote gender equality at an elementary school. Analyzing the stages of preparation for fieldwork, situating the self in ... -
Von Neumann Algebras for Abstract Harmonic Analysis
(University of Waterloo, 2008-08-28)This thesis develops the theory of operator algebras from the perspective of abstract harmonic analysis, and in particular, the theory of von Neumann algebras. Results from operator algebras are applied to the study of ... -
The Vortex Dynamics of Laminar Separation Bubbles
(University of Waterloo, 2021-01-15)Laminar separation bubbles (LSBs) are common features in low Reynolds number flows, and can have considerable performance impacts in applications such as hydrofoils, small-to-medium scale wind turbines, micro and unmanned ... -
Vortex Dynamics within the Laminar Separation Bubble over a NACA 0018 Airfoil at Low Reynolds Numbers
(University of Waterloo, 2015-11-02)The structures formed in the separated shear layer within a Laminar Separation Bubble (LSB) over a NACA 0018 airfoil at a chord Reynolds number of 100,000 and Angles of Attack (AOA) of (5°, 8°, and 10°) were investigated. ... -
Vortex-induced vibrations of a circular cylinder in elevated turbulence and unsteady freestream conditions
(University of Waterloo, 2024-04-26)This thesis presents the results of a series of experimental investigations focused on exploring one degree of freedom (1-DOF) vortex-induced vibrations (VIV) of a rigid, circular cylinder in two practical flow conditions: ... -
Vortex-induced vibrations of a pivoted circular cylinder and their control using a tuned-mass damper
(University of Waterloo, 2011-05-19)Vortex-induced vibrations of a pivoted circular cylinder and control of these vibrations were investigated experimentally. A novel experimental setup was employed to reproduce orbiting response observed in some engineering ... -
Voting-Based Consensus of Data Partitions
(University of Waterloo, 2008-08-29)Over the past few years, there has been a renewed interest in the consensus problem for ensembles of partitions. Recent work is primarily motivated by the developments in the area of combining multiple supervised learners. ... -
vProfile: Voltage-Based Sender Identification on Controller Area Networks
(University of Waterloo, 2021-08-25)Modern vehicles are becoming more accessible targets for cyberattacks due to the proliferation of wireless communication channels. The intra-vehicle Controller Area Network (CAN) bus lacks sender authentication, exposing ... -
