The Steiner Ratio for the Obstacle-Avoiding Steiner Tree Problem
(University of Waterloo, 2008-09-26)This thesis examines the (geometric) Steiner tree problem: Given a set of points P in the plane, find a shortest tree interconnecting all points in P, with the possibility of adding points outside P, called the Steiner ... -
A step at a time: An investigation of preschoolers’ simulations of narrative events during story comprehension
(University of Waterloo, 2010-04-23)A growing body of work suggests that narrative comprehension involves the simulation of the events and actions described in a narrative (e.g., Barsalou, 2008; Matlock, 2004). Preliterate children’s ability to simulate a ... -
Step into the Void: A Study of Spatial Perception in Virtual Reality
(University of Waterloo, 2019-02-13)The introduction of virtual reality (VR) into the architectural profession offers an unprecedented opportunity to experience unbuilt designs at full scale. The premise of the technology is that it gives users the illusion ... -
A Step Towards Sustainable Transportation Behaviour: Understanding automobile ownership and mode choice through qualitative research
(University of Waterloo, 2007-09-27)It is now widely recognized that society’s over-reliance on the automobile contributes to environmental problems, especially in urban areas. Nevertheless, efforts to bring about modal shifts through transportation demand ... -
Stereocoherence thresholds as a measure of global stereopsis
(University of Waterloo, 2017-06-14)Purpose: The purpose of this study was to develop a robust and reliable clinical test of stereopsis that is complementary to the conventional disparity threshold tests. Methods: Random dot stereograms containing ... -
Stereoscopic image quality assessment by deep convolutional neural network
(Elsevier, 2019-01)In this paper, we propose a no-reference (NR) quality assessment method for stereoscopic images by deep convolutional neural network (DCNN). Inspired by the internal generative mechanism (IGM) in the human brain, which ... -
Stiffness and stability of deployable pantographic columns

Still Wandering: Tales from the Diaspora
(University of Waterloo, 2018-09-21)As human beings, we are compelled to establish relationships and develop communities; we practice finding meaning in these things. However, no matter how much effort goes into their creation, and no matter how rich they ... -
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 ... -
Stimuli-responsive releasing of gold nanoparticles and liposomes from aptamer-functionalized hydrogels
(Institute of Physics, 2011-11-21)Controlled release of therapeutic agents is important for improving drug efficacy and reducing toxicity. Recently, hydrogels have been used for controlled release applications. While the majority of the previous work focused ... -
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 ... -
Stitch Bond Process of Pd-Coated Cu Wire: Experimental and Numerical Studies of Process Parameters and Materials
(IMAPS, 2013)Cost reduction is the main driver in the recent transition to Cu wire bonding from predominate Au wire bonding. Other cost reduction in packaging comes from new developments in substrates and lead frames, for example, ... -
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 decomposition for ℓp-norm symmetric survival functions on the positive orthant
(Elsevier, 2021-07)We derive a stochastic representation for the probability distribution on the positive orthant (0,∞)ᵈ whose association between components is minimal among all probability laws with ℓp-norm symmetric survival functions. ...
