Spatial and temporal assessment of rural-urban land-use gradient effects on water quality and periphyton communities in tributaries of Durham Region, Ontario
(2016-08-01)This study examines the effects of longitudinal and local land-use gradients on water quality and periphyton within four watersheds representing varying rural-urban land-use types and intensities. Although numerous studies ... -
Spatial peripheral interaction techniques for viewing and manipulating off-screen digital content
(2015-08-01)When an information space is larger than the display, it is typical for interfaces to only support interacting with content that is rendered within its viewport. To support interacting with off-screen content, our work ... -
Spatial sound and sound localization on a horizontal surface for use with interactive surface (tabletop) computers
(2012-08-01)Tabletop computers (also known as surface computers, smart tables, and interactive surface computers) have been growing in popularity for the last decade and are poised to make in-roads into the consumer market, opening ... -
Special isotopes of the FUGEN nuclear reactor
(2022-04-01)The Canadian and Japanese nuclear regulatory bodies have shown dissimilarities between the isotopes considered to be of interest in decommissioning similarly styled heavy water reactors. This research examines the quantity ... -
Specifics of forced-convection heat transfer in a vertical 7-element bundle cooled with upward flow of SuperCritical Water
(2020-08-17)Current Generation II/III/III+ Nuclear Power Plants (NPPs) are no longer economically competitive partially due to low thermal efficiencies. Six Generation IV NPP concepts were proposed having increased thermal efficiency, ... -
Specifics of forced-convection heat transfer to supercritical water flowing upward in annular and bundle flow geometries
(2016-08-01)Since annulus- and bundle-flow geometries impede coolant flow, heat transfer to the coolant would occur differently than in bare tubes. The main objective of this work is to propose and verity a universal method to accurately ... -
Specifics of forced-convective heat transfer to supercritical CO2 flowing upward in vertical bare tubes
(2015-04-01)Heat transfer in the forced convection regime of fluids at supercritical conditions has been studied extensively for the past 60 years. The dominant approach to summarize the experimental results was by proposing empirical ... -
Spectrum sensing based on capon power spectral density estimation
(2015-04-01)Cognitive radio (CR) technology has evolved to solve the spectrum scarcity problem and improve spectrum utilization. Spectrum sensing is a CR function that allows secondary users to efficiently utilize the spectrum without ... -
Spectrum sharing for multi-user massive MIMO networks
(2023-12-01)In this dissertation, we propose a creative approach to advance 5G network technologies by investigating the impact of employing an underlay spectrum sharing (USS) scheme on the performance of two massive multi-input-multi-output ... -
Spectrum sharing for two-way relay networks
(2015-07-01)We consider a communication network consisting of two transceiver nodes, one relay node, and one receiving node. The relay enables a two-way communication between the two transceivers and meanwhile sends its own information ... -
Spring Stepper: a makerspace controller for seated hands-free locomotion in virtual reality
(2019-12-01)Natural locomotion is crucial for improving presence in a virtual environment (VE), while also reducing simulator sickness. While research in various areas of virtual reality (VR), such as head-mounted displays (HMD) and ... -
Squeegee Punks reunite: safe streets for all: an insider qualitative study
(2023-06-01)Squeegee Punks were a fixture on many busy street corners in urban cities in Canada in the mid to late 1990s. During the height of the squeegee kid phenomenon, multiple studies were conducted on how squeegee work impacted ... -
Stability of heroin metabolites and oxycodone in rat hair and liver during decomposition
(2010-01-01)The aim of this study was to investigate the influence of soft tissue decomposition on the stability of drugs incorporated in hair antemortem. Two burial trials were conducted: in the first trial, rats were administered ... -
Starting the conversation: a phenomenological study exploring registered dietitian’s lived experience counseling children living with obesity and their families.
(2014-08-01)This study was completed in order to gain an understanding of Registered Dietitian’s lived experiences counseling children living with obesity and their families. Between November 2013 and March 2014, 8 Registered Dietitians ... -
STDMn+p0: a multidimensional patient oriented data mining framework for critical care research
(2011-04-01)In the neonatal intensive care unit (NICU) environment, critical care and treatment directly correlate to the multidimensional development of an infant and are influenced by attributes such as gender and gestational age ... -
Steam-reheat option for supercritical-water-cooled reactors
(2010-12-01)SuperCritical-Water-cooled Reactors (SCWRs) are being developed as one of the Generation-IV nuclear-reactor concepts. Main objectives of the development are to increase thermal efficiency of a Nuclear Power Plant (NPP) and ... -
Stereoscopic depth axis interaction: A study of performance and engagement in stereoscopic 3D games.
(2014-01-01)Game developers strive to maximize immersion and engagement, to emotionally involve the audience in their material. One technique used to increase engagement is the development of new technologies, such as Stereoscopic ... -
StoryPass: a system and study for memorable secure passphrases.
(2014-10-01)The goal of this thesis is to study the implementation of a passphrase system that implements new creation policies, called StoryPass. We are motivated to do this research as current text-based authentication methods, ... -
StoryTIME: development of a tangible interface for storytelling
(2018-08-01)The production of 3D digital animated sequences is an iterative process where ideas are scrutinized by members of the production team until they are finalized. Production teams are comprised of many individuals with varying ... -
