Virtual Network Embedding with Path-based Latency Guarantees in Elastic Optical Networks
(University of Waterloo, 2019-10-21)Elastic Optical Network (EON) virtualization has recently emerged as an enabling technology for 5G network slicing. A fundamental problem in EON slicing (known as Virtual Network Embedding (VNE)) is how to efficiently map ... -
Virtual PCF: Improving VoIP over WLAN performance with legacy clients
(University of Waterloo, 2009-07-22)Abstract Voice over IP (VoIP) is one of the fastest growing applications on the Internet. Concurrently, 802.11 Wireless LANs (WLANs) have become ubiquitous in residential, enterprise, campus and public networks. Currently ... -
VisConductor: Affect-Varying Gestural Widgets for Animating Dynamic Data Visualization in Augmented Video Presentations
(University of Waterloo, 2023-12-12)To enhance presentations involving data in remote settings, we introduce VisConductor, an authoring and presentation tool that allows presenters to manipulate data visualizations overlaid on their webcam feed with hand ... -
Viscous Liquid Animation with Spatially Adaptive Grids
(University of Waterloo, 2018-01-08)Viscous fluid behaviors are among the most complex yet familiar physical phenomena we encounter in everyday life. Much attention and investigation has been paid to the creation of visually realistic results, especially ... -
The Visibility Freeze-Tag Problem
(University of Waterloo, 2014-08-25)In the Freeze-Tag Problem, we are given a set of robots at points inside some metric space. Initially, all the robots are frozen except one. That robot can awaken (or “unfreeze”) another robot by moving to its position, ... -
Vision-Based Observation Models for Lower Limb 3D Tracking with a Moving Platform
(University of Waterloo, 2011-08-23)Tracking and understanding human gait is an important step towards improving elderly mobility and safety. This thesis presents a vision-based tracking system that estimates the 3D pose of a wheeled walker user's lower ... -
Visualizing and Understanding Code Duplication in Large Software Systems
(University of Waterloo, 2006-12-22)Code duplication, or code cloning, is a common phenomena in the development of large software systems. Developers have a love-hate relationship with cloning. On one hand, cloning speeds up the development process. On the ... -
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 ... -
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 ... -
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 Vulcan game of Kal-toh: Finding or making triconnected planar subgraphs
(University of Waterloo, 2011-04-28)In the game of Kal-toh depicted in the television series Star Trek: Voyager, players attempt to create polyhedra by adding to a jumbled collection of metal rods. Inspired by this fictional game, we formulate graph-theoretical ... -
“Wait and see” vaccinating behavior during a pandemic: a game theoretic analysis
(Elsevier, 2011-07-26)During the 2009 H1N1 pandemic, many individuals adopted a “wait and see” approach to vaccinating until further information was available on the course of the pandemic and emerging vaccine risks. This behaviour implies two ... -
Waiting Time Distributions in the Preemptive Accumulating Priority Queue
(Springer, 2017-03-01)We consider a queueing system in which a single server attends to N priority classes of customers. Upon arrival to the system, a customer begins to accumulate priority linearly at a rate which is distinct to the class to ... -
A walk through quantum noise: a study of error signatures and characterization methods
(University of Waterloo, 2019-09-17)The construction of large scale quantum computing devices might be one of the most exciting and promising endeavors of the 21st century, but it also comes with many challenges. As quantum computers are supplemented with ... -
Walking Onions: Scaling Distribution of Information Safely in Anonymity Networks
(University of Waterloo, 2020-08-07)Scaling anonymity networks offers unique security challenges, as attackers can exploit differing views of the network’s topology to perform epistemic and route capture attacks. Anonymity networks in practice, such as ... -
Wall turbulence response to surface cooling and formation of strongly stable stratified boundary layers
(AIP, 2019-08-20)This paper investigates the processes by which stable boundary layers are formed through strong surface cooling imposed on neutrally stratified wall-bounded turbulence using high-resolution direct numerical simulation at ... -
Wasserstein Adversarial Robustness
(University of Waterloo, 2020-09-21)Deep models, while being extremely flexible and accurate, are surprisingly vulnerable to ``small, imperceptible'' perturbations known as adversarial attacks. While the majority of existing attacks focus on measuring ... -
Wasserstein Autoencoders with Mixture of Gaussian Priors for Stylized Text Generation
(University of Waterloo, 2021-01-28)Probabilistic text generation is an important application of Natural Language Processing (NLP). Variational autoencoders and Wasserstein autoencoders are two widely used methods for text generation. New research efforts ... -
WatchTrace: Design and Evaluation of an At-Your-Side Gesture Paradigm
(University of Waterloo, 2017-11-16)In this thesis, we present the exploration and evaluation of a gesture interaction paradigm performed with arms at rest at the side of one's body. This gesture stance is informed persisting challenges in mid-air arm gesture ... -
