Weak Moment Maps in Multisymplectic Geometry
(University of Waterloo, 2018-07-04)We introduce the notion of a weak (homotopy) moment map associated to a Lie group action on a multisymplectic manifold. We show that the existence/uniqueness theory governing these maps is a direct generalization from ... -
Weakly-supervised Semantic Segmentation with Regularized Loss Hyperparameter Search
(University of Waterloo, 2021-09-20)Weakly supervised segmentation signi cantly reduces user annotation e ort. Recently, regularized loss was proposed for single object class segmentation under image-level weak supervision. Regularized loss consists of ... -
Weaving a Faster Tor: A Multi-Threaded Relay Architecture for Improved Throughput
(University of Waterloo, 2020-08-10)The Tor anonymity network has millions of daily users and thousands of volunteer-run relays, but growing it further has several research and deployment challenges. One such challenge is supporting the increase in bandwidth ... -
Web Data Integration for Non-Expert Users
(University of Waterloo, 2018-04-26)oday, there is an abundance of structured data available on the web in the form of RDF graphs and relational (i.e., tabular) data. This data comes from heterogeneous sources, and realizing its full value requires integrating ... -
Web Search, Web Tutorials & Software Applications: Characterizing and Supporting the Coordinated Use of Online Resources for Performing Work in Feature-Rich Software
(University of Waterloo, 2015-08-06)Web search and other online resources serve an integral role in how people learn and use feature-rich software (e.g., Adobe Photoshop) on a daily basis. Users depend on web resources both as a first line of technical ... -
A Web-based Statistical Analysis Framework
(University of Waterloo, 2007-04-26)Statistical software packages have been used for decades to perform statistical analyses. Recently, the emergence of the Internet has expanded the potential for these packages. However, none of the existing packages have ... -
Website Fingerprinting on LEO Satellite Internet
(University of Waterloo, 2024-01-24)Although encrypted channels, like those provided by anonymity networks such as Tor, have been put into effect, network adversaries have proven their capability to undermine users' browsing privacy through website fingerprinting ... -
Website Fingerprinting: Attacks and Defenses
(University of Waterloo, 2016-01-13)Website fingerprinting attacks allow a local, passive eavesdropper to determine a client's web activity by leveraging features from her packet sequence. These attacks break the privacy expected by users of privacy technologies, ... -
Weighting Document Genre in Enterprise Search
(University of Waterloo, 2007-08-14)The creation of an Enterprise Search system involves many challenges that are not present in Web search. Searching a corporate collection is influenced both by the structure of the data present in the collection and by ... -
The Weil conjectures
(University of Waterloo, 2008-01-24)In discussing the question of rational points on algebraic curves, we are usually concerned with ℚ. André Weil looked instead at curves over finite fields; assembling the counts into a function, he discovered that it ... -
Welch Bounds and Quantum State Tomography
(University of Waterloo, 2008-12-22)In this thesis we investigate complete systems of MUBs and SIC-POVMs. These are highly symmetric sets of vectors in Hilbert space, interesting because of their applications in quantum tomography, quantum cryptography and ... -
Well-Posedness of Boundary Control Systems
(Society for Industrial and Applied Mathematics, 2003-01-01)Continuity of the input/output map for boundary control systems is shown through the system transfer function. Our approach transforms the question of continuity of the input/output map of a boundary control system to ... -
What is a field, what is a particle?
(University of Waterloo, 2019-01-25)Much of the structure of quantum field theory (QFT) is predicated on the principle of locality. Adherence to locality is achieved in Algebraic QFT (AQFT) by the association of algebras of observables with regions of ... -
Which classes of structures are both pseudo-elementary and definable by an infinitary sentence?
(2019-03-21)When classes of structures are not first-order definable, we might still try to find a nice description. There are two common ways for doing this. One is to expand the language, leading to notions of pseudo-elementary ... -
White Paper: Measuring Research Outputs Through Bibliometrics
(University of Waterloo, 2016)This White Paper provides a high-level review of issues relevant to understanding bibliometrics, and practical recommendations for how to appropriately use these measures. This is not a policy paper; instead, it defines ... -
Wholetoning: Synthesizing Abstract Black-and-White Illustrations
(University of Waterloo, 2009-02-18)Black-and-white imagery is a popular and interesting depiction technique in the visual arts, in which varying tints and shades of a single colour are used. Within the realm of black-and-white images, there is a set of ... -
Wikipedia-Based Semantic Enhancements for Information Nugget Retrieval
(University of Waterloo, 2008-05-16)When the objective of an information retrieval task is to return a nugget rather than a document, query terms that exist in a document often will not be used in the most relevant nugget in the document for the query. In ... -
WiseBench: A Motion Planning Benchmarking Framework for Autonomous Vehicles
(University of Waterloo, 2020-10-01)Rapid advances in every sphere of autonomous driving technology have intensified the need to be able to benchmark and compare different approaches. While many benchmarking tools tailored to different sub-systems of an ... -
WKB Analysis of Tunnel Coupling in a Simple Model of a Double Quantum Dot
(University of Waterloo, 2008-12-16)A simplified model of a double quantum dot is presented and analyzed, with applications to spin-qubit quantum computation. The ability to trap single electrons in semiconductor nanostructures has led to the proposal of ... -
WLAN Interface Management on Mobile Devices
(University of Waterloo, 2008-08-15)The number of smartphones in use is overwhelmingly increasing every year. These devices rely on connectivity to the Internet for the majority of their applications. The ever-increasing number of deployed 802.11 ...
