The Limited Effectiveness of Neural Networks for Simple Question Answering on Knowledge Graphs
(University of Waterloo, 2017-12-08)Simple factoid question answering (QA) is a task, where the questions can be answered by looking up a single fact in the knowledge base (KB). However, this QA task is difficult, since retrieving a single supporting fact ... -
Limiting techniques for the discontinuous Galerkin method on unstructured meshes
(University of Waterloo, 2022-08-18)Many complex phenomena like shock-shock interactions, shock-vortex interactions, stratified flows, etc., are governed by nonlinear hyperbolic conservation laws. Higher order numerical schemes like the discontinuous Galerkin ... -
The Limits of Incrementalism: The G20, the FSB, and the International Regulatory Agenda
(De Gruyter, 2012-01)At their very first summit in Washington in November 2008, the G20 leaders placed the reform of international financial regulation at the core of their agenda. The issue has retained a central place in discussions and ... -
THE LIMITS TO INFLUENCE: THE CLUB OF ROME AND CANADA, 1968 TO 1988
(University of Waterloo, 2006)This dissertation is about influence which is defined as the ability to move ideas forward within, and in some cases across, organizations. More specifically it is about an extraordinary organization called the Club of ... -
A Line in Motion
(University of Waterloo, 2009-06-19)This is a graphic account, showing various spaces found in a work of Chinese calligraphy, using, for analysis, the work of contemporary calligrapher Noriko Maeda, historical examples by Wang Hui, Wang Xizhi, Wen Cheng Ming, ... -
Line-based deep learning method for tree branch detection from digital images
(Elsevier, 2022-06)Preventive maintenance of power lines, including cutting and pruning of tree branches, is essential to avoid interruptions in the energy supply. Automatic methods can support this risky task and also reduce time consuming. ... -
Line-Scan Spectral-Domain Optical Coherence Tomography for Cellular Resolution Structural and Vascular Imaging of Biological Tissues
(University of Waterloo, 2022-06-07)Optical coherence tomography (OCT) is an optical interferometric technique for non-invasive contactless imaging of the cellular-level structures of biological tissues. However, the application of OCT for in-vivo volumetric ... -
A Linear Algebraic Method on the Chromatic Symmetric Function
(University of Waterloo, 2023-08-28)The Stanley-Stembridge conjecture is a longstanding conjecture that has evaded proof for nearly 30 years. Concerned with the e-basis expansions of the chromatic symmetric functions of unit-interval graphs, this conjecture ... -
Linear and Non-linear Monotone Methods for Valuing Financial Options Under Two-Factor, Jump-Diffusion Models
(University of Waterloo, 2007-10-01)The evolution of the price of two financial assets may be modeled by correlated geometric Brownian motion with additional, independent, finite activity jumps. Similarly, the evolution of the price of one financial asset ... -
Linear and Nonlinear Regression Techniques for Simultaneous and Proportional Myoelectric Control
(Institute of Electrical and Electronics Engineers, 2014-03-01)In recent years the number of active controllable joints in electrically powered hand-prostheses has increased significantly. However, the control strategies for these devices in current clinical use are inadequate as they ... -
Linear Approximations For Factored Markov Decision Processes
(University of Waterloo, 2004)A Markov Decision Process (MDP) is a model employed to describe problems in which a decision must be made at each one of several stages, while receiving feedback from the environment. This type of model has been extensively ... -
Linear Interactive Encoding and Decoding Schemes for Lossless Source Coding with Decoder Only Side Information
(University of Waterloo, 2008-08-29)Near lossless source coding with side information only at the decoder, was first considered by Slepian and Wolf in 1970s, and rediscovered recently due to applications such as sensor network and distributed video coding. ... -
Linear Macro-Micro Positioning System Using a Shape Memory Alloy Actuator
(University of Waterloo, 2004)The use of high-precision automated equipment is steadily increasing due in part to the progressively smaller sizes of electronic circuits. Currently, piezoelectric transducers (piezos) dominate as the actuation device ... -
Linear MMSE Receivers for Interference Suppression & Multipath Diversity Combining in Long-Code DS-CDMA Systems
(University of Waterloo, 2003)This thesis studies the design and implementation of a linear minimum mean-square error (LMMSE) receiver in asynchronous bandlimited direct-sequence code-division multiple-access (DS-CDMA) systems that employ long-code ... -
Linear optical characterization of graphene structure
(University of Waterloo, 2018-01-04)Graphene as a newly developed 2D material has attracted a lot of attention for its promising applications in optoelectronic fields. To pursue a profound understanding of its optical properties, this thesis presents the ... -
Linear preservers of polynomial numerical hulls of matrices
(Elsevier, 2019-08-15)Let Mn be the algebra of all n × n complex matrices, 1 ≤ k ≤ n − 1 be an integer, and φ : Mn −→ Mn be a linear operator. In this paper, it is shown that φ preserves the polynomial numerical hull of order k if and only if ... -
