Constructing multilingual selves. Subjective perspectives on learning and living with German as a "heritage" language in Canada
(University of Waterloo, 2018-12-14)Based on the perception that language students who have a family background in the target language differ from ‘typical’ foreign language learners in important ways, the phenomenon of what has been termed "heritage language ... -
Preferential flowpaths and fertilizer placement influence subsurface P transport across soil textures and seasonal conditions
(University of Waterloo, 2018-12-14)Agricultural tile drains are a source of phosphorus (P) contributing to eutrophication. Preferential flowpaths can rapidly transport P to tile drains, but their activation in different soil textures and under variable ... -
Development, Optimization and Testing of an Innovative Wedge Anchorage for CFRP Plates
(University of Waterloo, 2018-12-14)Replacing degraded concrete structures can be quite expensive and time consuming; thus, strengthening these structures with fiber reinforced polymer (FRP) elements, such as carbon FRP (CFRP) plates, is more practical. ... -
A Multi-scale model for CO2 capture: A Nickel-based oxygen carrier in Chemical-looping Combustion
(Elsevier, 2018-01-01)In this work, we present a multi-scale modelling framework for the Ni-based oxygen carrier (OC) particle that can explicitly account for the complex reaction mechanism taking place on the contacting surface between gas and ... -
Multilevel Monte Carlo for noise estimation in stochastic multiscale systems
(Elsevier, 2018-12-01)The purpose of this study is to adapt Multilevel Monte Carlo (MLMC) sampling technique for random noise estimation in stochastic multiscale systems and evaluate the performance of this method. The system under consideration ... -
An integrated personnel allocation and machine scheduling problem for industrial size multipurpose plants
(Elsevier, 2018-01-01)This paper describes the development and implementation of an optimization model to solve the integrated problem of personnel allocation and machine scheduling for industrial size multipurpose plants. Although each of these ... -
A comprehensive study of geothermal heating and cooling systems
(Elsevier, 2019-01-01)Geothermal heat is an energy source that is local, reliable, resilient, environmentally-friendly, and sustainable. This natural energy is produced from the heat within the earth, and has different applications, such as ... -
Recent advances on first-principles modeling for the design of materials in CO2 capture technologies
(Elsevier, 2018-11-10)Novel technologies in consideration of industrial sustainability (IS) are in urgent need to satisfy the increasing demands from the society. IS realizes the production of materials and while maintaining environmental and ... -
A non-local plasticity model of stimulated volume evolution during hydraulic fracturing
(Elsevier, 2018-10-02)Hydraulic fracturing in naturally fractured rocks often leads to the creation of a stimulated zone in which the target rock formation is deformed and fractured by the reactivation and shear dilation of natural fractures ... -
School start time changes in the COMPASS study: associations with youth sleep duration, physical activity, and screen time
(Elsevier, 2018-10-12)Background To date, no longitudinal population-based studies of school start times have been conducted within Canada. School schedule changes provided an opportunity to examine start times in association with youth sleep, ... -
Design and development of pH-responsive polyurethane membranes for intravaginal release of nanomedicines
(Elsevier, 2018-12-01)The objective of this study was to develop and characterize a novel intravaginal membrane platform for pH-triggered release of nanoparticles (NPs), which is essential for efficient intravaginal delivery of certain effective ... -
Empirical validation of the Gamification User Types Hexad scale in English and Spanish
(Elsevier, 2018-10-13)Gamification, the use of game elements in non-game systems, is now established as a relevant research field in human-computer interaction (HCI). Several empirical studies have shown that gameful interventions can increase ... -
Using pattern recognition to detect differences in movement strategy between high and low relative biomechanical exposure lifts and lifters: Application to backboard lifting
(University of Waterloo, 2018-12-13)Introduction: Backboard lifting is a demanding aspect of paramedic work that results in higher low back moments and sagittal trunk angles compared to other paramedic tasks. Movement strategy in a backboard lift affects ... -
Crystallization Studies of Highly Monodisperse Oligomeric Poly(Ethylene Oxide)
(University of Waterloo, 2018-12-13)Poly(ethylene oxide) is one of the most intensively studied polymers in terms of crystallization, because of its linear structure. In this thesis the chapters are organized in a self-contained fashion, with a general ... -
Hydrobiogeophysics: Linking geo-electrical properties and biogeochemical processes in shallow subsurface environments
(University of Waterloo, 2018-12-13)Microbially mediated reactions drive (bio)geochemical cycling of nutrients and contaminants in shallow subsurface environments. Environmental forcings exert a strong control on the timing of reactions and the spatial ... -
Pricing and Hedging of Emerging Products in Finance and Insurance
(University of Waterloo, 2018-12-12)This thesis addresses the pricing and hedging issues on the newly-developed financial and insurance products, including simplified hedges for path-dependent options, variable annuities tied with state-dependent fees, and ... -
Cooperative Autonomous Vehicle Speed Optimization near Signalized Intersections
(University of Waterloo, 2018-12-12)Road congestion in urban environments, especially near signalized intersections, has been a major cause of significant fuel and time waste. Various solutions have been proposed to solve the problem of increasing idling ... -
Portraits from the State Mental Hospitals
(University of Waterloo, 2018-12-12)The thesis is a short book of fifty sketches. I felt I threw out a significant amount of other material – plans, sketchup models, physical models, and photographs. Many people I had shown my work to were uninterested in ... -
Highly pressurized partially miscible liquid-liquid flow in a micro-T-junction. I. Experimental observations
