Semantic Order Compatibilities and Their Discovery
(University of Waterloo, 2019-09-20)Ordered domains such as numbers and dates are common in real-life datasets. The SQL standard includes an ORDER BY clause to sort the results, and there has been research work on formalizing, reasoning about, and automatically ... -
Semantic Search and Visual Exploration of Computational Notebooks
(University of Waterloo, 2021-08-12)Code search is an important and frequent activity for developers using computational notebooks (e.g., Jupyter). The flexibility of notebooks brings challenges for effective code search, where classic search interfaces for ... -
Semantic-Based Context-Aware Service Discovery in Pervasive-Computing Environments
(University of Waterloo, 2007-01-08)Recent technological advancements are enabling the vision of pervasive or ubiquitous computing to become a reality. Service discovery is vital in such a computing paradigm, where a great number of devices and software ... -
A Semi-Supervised Approach to the Construction of Semantic Lexicons
(University of Waterloo, 2012-03-21)A growing number of applications require dictionaries of words belonging to semantic classes present in specialized domains. Manually constructed knowledge bases often do not provide sufficient coverage of specialized ... -
Semicrossed Products, Dilations, and Jacobson Radicals
(University of Waterloo, 2017-08-18)We compute the C*-envelope of the isometric semicrossed product of a C*-algebra arising from number theory by the multiplicative semigroup of a number ring R, and prove that it is isomorphic to T[R], the left regular ... -
Semidefinite Embedding for the Dimensionality Reduction of DNA Microarray Data
(University of Waterloo, 2006)Harnessing the power of DNA microarray technology requires the existence of analysis methods that accurately interpret microarray data. Current literature abounds with algorithms meant for the investigation of microarray ... -
Semidefinite Facial Reduction for Low-Rank Euclidean Distance Matrix Completion
(University of Waterloo, 2010-04-27)The main result of this thesis is the development of a theory of semidefinite facial reduction for the Euclidean distance matrix completion problem. Our key result shows a close connection between cliques in the graph of ... -
Semidefinite Programming Relaxations of the Simplified Wasserstein Barycenter Problem: An ADMM Approach
(University of Waterloo, 2023-05-04)The Simplified Wasserstein Barycenter problem, the problem of picking k points each chosen from a distinct set of n points as to minimize the sum of distances to their barycenter, finds applications in various areas of ... -
Semiparametric Empirical Likelihood Inference under Two-sample Density Ratio Models
(University of Waterloo, 2021-08-27)The semiparametric density ratio model (DRM) provides a flexible and useful platform for combining information from multiple sources. It has been widely used in many fields. This thesis considers several important inference ... -
Semiparametric inference on the means of multiple nonnegative distributions with excess zero observations
(Elsevier, 2018-07-01)A non-standard, but not uncommon, situation is to observe multiple samples of nonnegative data which have a high proportion of zeros. This is the so-called excess of zeros situation and this paper looks at the problem of ... -
Semiparametric Methods for the Analysis of Progression-Related Endpoints
(University of Waterloo, 2013-05-22)Use of progression-free survival in the evaluation of clinical interventions is hampered by a variety of issues, including censoring patterns not addressed in the usual methods for survival analysis. Progression can be ... -
Semiparametric recurrent event vs time-to-first-event analyses in randomized trials: Estimands and model misspecification
(John Wiley & Sons Ltd., 2021-04-20)Insights regarding the merits of recurrent event and time-to-first-event analyses are needed to provide guidance on strategies for analyzing intervention effects in randomized trials involving recurrent event responses. ... -
Semistable rank 2 co-Higgs bundles over Hirzebruch surfaces
(University of Waterloo, 2015-08-07)It has been observed by S. Rayan that the complex projective surfaces that potentially admit non-trivial examples of semistable co-Higgs bundles must be found at the lower end of the Enriques-Kodaira classification. ... -
Sensitivity Analysis and Robust Optimization: A Geometric Approach for the Special Case of Linear Optimization
(University of Waterloo, 2018-12-21)In this thesis, we study the special case of linear optimization to show what may affect the sensitivity of the optimal value function under data uncertainty. In this special case, we show that the robust optimization ... -
Sensitivity of Idealized Squall Line Simulation to Resolution and Subgrid Turbulence Mixing
(University of Waterloo, 2019-01-23)In this project, the sensitivity of idealized squall line simulations to horizontal grid spacing and turbulent mixing parameterization will be discussed. Inconsistent results from numerical simulations of convective ... -
Sensitivity of the Thermal Structure and Circulation Patterns of a Simple Idealized Lake and Lake Erie to External Driving Forces
(University of Waterloo, 2022-12-22)Lake Erie has been a great source of economic growth and drinking water for both Canada and the United States. All lakes in temperate regions that stratify during summer are prone to hypoxia as they will experience some ... -
Sensor Choice for Minimum Error Variance Estimation
(Institute of Electrical and Electronics Engineers, 2017-06-12)A Kalman filter is optimal in that the variance of the error is minimized by the estimator. It is shown here, in an infinite-dimensional context, that the solution to an operator Riccati equation minimizes the steady-state ... -
Sentiment Lexicon Induction and Interpretable Multiple-instance Learning in Financial Markets
(University of Waterloo, 2020-09-28)Sentiment analysis has been widely used in the domain of finance. There are two most common textual sentiment analysis methods in finance: \textit{dictionary-based approach} and \textit{machine learning approach}. The ... -
Separable State Discrimination Using Local Quantum Operations and Classical Communication
(University of Waterloo, 2013-08-30)In this thesis we study the subset of quantum operations that can be implemented using only local quantum operations and classical communication (LOCC). This restricted paradigm serves as a tool to study not only quantum ... -
The Separate Compilation Assumption
(University of Waterloo, 2014-09-19)Call graphs are an essential requirement for almost all inter-procedural analyses. This motivated the development of many tools and frameworks to generate the call graph of a given program. However, the majority of these ...
