Stille Coupling of α-Acyloxybenzylstannanes with Acid Chlorides
(University of Waterloo, 2016-08-19)Two widely-accepted models (open- and cyclic- transmetalation) are applied to explain the stereochemical outcome of the Stille coupling with organotin compounds containing an sp3 chiral center. However, it is still not ... -
Stille Coupling of α-Alkoxybenzylstannanes: Optimization Study and Stereochemical Outcome
(University of Waterloo, 2011-08-24)In order to make the stereospecific palladium-catalyzed cross-coupling of α-alkoxybenzyl-stannanes a useful synthetic methodology, optimization was undertaken to improve the coupling yields between these stannanes and ... -
Stille Coupling Reactions Involving α-Alkoxybenzylstannanes
(University of Waterloo, 2007-12-20)The Stille reaction has established itself as one of the two most general and most selective palladium-catalyzed cross-coupling reactions, along with the Suzuki cross-coupling of organoboron compounds. The Stille coupling ... -
Stimulating In Situ Denitrification in an Aerobic, Highly Conductive Municipal Drinking Water Aquifer
(University of Waterloo, 2010-04-14)Best or beneficial management practices (BMPs) are often relied upon as a mitigation strategy for nitrate contamination throughout Canada. At a regional scale, reducing the quantity of nutrients applied to agricultural ... -
Stimulus characteristics of a novel air-based multiple stimulus aesthesiometer
(University of Waterloo, 2022-01-05)Purpose: To (1) develop a novel air-based aesthesiometer capable of producing and applying multiple stimuli separated either by time or space; (2) identify the stimulus airflow characteristics and confirm the consistency ... -
A Stimulus-Response Account of Stroop and Reverse Stroop Effects
(University of Waterloo, 2006)This thesis concerns selective attention in the context of the Stroop task (identify the colour) and Reverse Stroop task (identify the word). When a person is asked to select and identify one dimension of a bidimensional ... -
A Stochastic Approach to Measurement-Driven Damage Detection And Prognosis in Structural Health Monitoring
(University of Waterloo, 2017-12-08)Damage detection and prognosis are integral to asset management of critical mechanical and civil engineering infrastructure. In practice, these two aspects are often decoupled, where the former is carried out independently ... -
Stochastic Clearing Systems With Markovian Inputs: Performance Evaluation and Optimal Policies
(University of Waterloo, 2015-09-01)This thesis studies the stochastic clearing systems which are characterized by a non-decreasing stochastic input process {Y(t), t > 0}, where Y(t) is the cumulative quantity entering the system in [0, t], and an output ... -
Stochastic Effects and Fractal Kinetics in the Pharmacokinetics of Drug Transport
(University of Waterloo, 2018-05-16)Pharmacokinetics (PK) attempts to model the progression and time evolution of a drug in the human body from administration to the elimination stage. It is the primary quantitative approach used in drug discovery/development ... -
Stochastic Environmental modeling for Nuclear Waste Management
(University of Waterloo, 2017-10-03)Deep geological repositories are identified as possible disposal site for safely isolating highly radioactive nuclear waste from affecting humans and the environment. These repositories are multi barrier systems and safety ... -
A Stochastic Framework for Soil-Structure Interaction and Constitutive Modelling
(University of Waterloo, 2019-08-19)A stochastic framework for soil-structure interaction and constitutive modelling is investigated in this thesis and developed to account for uncertainties in material properties and loading conditions. The development ... -
Stochastic Hybrid Model Predictive Control using Gaussian Processes for Systems with Piecewise Residual Dynamics
(University of Waterloo, 2023-08-17)Data-driven control methods have been used to provide performance and safety benefits for systems where lower fidelity nominal dynamics models are insufficient when operating systems at their limits. These methods typically ... -
Stochastic Lattice | A Generative Design Tool for Material Conscious Free Form Timber Surface Architecture
(University of Waterloo, 2012-05-16)This thesis attempts to resolve the contradictory relationship between the ecological merits of wood construction and the significant material intensity of recent free form timber surface structures. The building industry ... -
Stochastic Mechanisms for Truthfulness and Budget Balance in Computational Social Choice
(University of Waterloo, 2013-01-23)In this thesis, we examine stochastic techniques for overcoming game theoretic and computational issues in the collective decision making process of self-interested individuals. In particular, we examine truthful, stochastic ... -
Stochastic Minimum Norm Combinatorial Optimization
(University of Waterloo, 2022-07-28)Motivated by growing interest in optimization under uncertainty, we undertake a systematic study of designing approximation algorithms for a wide class of 1-stage stochastic-optimization problems with norm-based objective ... -
Stochastic Modeling and Analysis of Power Systems with Intermittent Energy Sources
(University of Waterloo, 2014-02-11)Electric power systems continue to increase in complexity because of the deployment of market mechanisms, the integration of renewable generation and distributed energy resources (DER) (e.g., wind and solar), the penetration ... -
