Semiconductor Nanowire Based Piezoelectric Energy Harvesters: Modeling, Fabrication, and Characterization
(University of Waterloo, 2015-12-22)Semiconductor nanowire (NW) arrays’ unique advantages over bulk forms, including enhanced surface area, high mechanical flexibility, high sensitivity to small forces, better charge collection, and enhanced light absorption ... -
The semiconductor properties of passive films and corrosion behavior of stainless steel reinforcing bars in simulated concrete pore solution
(Elsevier, 2019-06)The vulnerability of concrete reinforcing steels to corrosion when depassivation occurs, typically in the presence of chloride, makes it important to understand the nature of the steels’ passive films. In Part I of the ... -
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 for assignment and partitioning problems

A Semidefinite Programming Model for the Facility Layout Problem
(University of Waterloo, 2010-08-30)The continuous facility layout problem consists of arranging a set of facilities so that no pair overlaps and the total sum of the pairwise connection costs (proportional to the center-to-center rectilinear distance) is ... -
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 ... -
Semiosis and the Crisis of Meaning: Continuity and Play in Peirce and Derrida
(University of Waterloo, 2019-09-17)Semiosis and the Crisis of Meaning addresses the difference between continuity and play in Charles Peirce’s and Jacques Derrida’s theory of signs. The main aim is to offer a reply to Derrida’s reading of Peirce in 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. ... -
Semiquinone-Bridged bis-Dithiazolyls as Neutral Radical Conductors
(University of Waterloo, 2011-12-21)Radicals are potential building blocks to prepare conductive and magnetic materials. In order to achieve high conductivity, materials displaying a large bandwidth W and a low on-site Coulomb repulsion energy U must be ... -
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. ... -
Seniors and Cruising: Motivations and Satisfactions
(University of Waterloo, 2008-03-10)Millions of vacationers are taking a cruise each year and nearly one-third are senior tourists. There is little attention to this sector in the literature. This qualitative study reveals some of the motivations and ... -
Sense of Belonging, Peer Support, and Social Media: Examining the Mental Health, Well-Being and School to Work Transitions of Co-operative and Non-Co-operative Education Students
(University of Waterloo, 2016-01-04)The primary aim of this study was to examine student perceptions of sense of belonging, peer support, and student social media use and how these factors influence their mental health, overall well-being, and confidence ... -
Sense of Place and Walking Tours: A Case Study of the Tour Guys Downtown Toronto Tour
