Use of Supercritical Propylene to Produce Polypropylene/Clay Nanocomposites via in situ Polymerization
(University of Waterloo, 2014-05-02)Nanocomposites have been receiving a lot the attention in the last decade from both industry and academia, since a small amount of nanofiller can significantly improve the materials properties. In the field of thermoplastics, ... -
Use of Technological Tools for Supporting Interpersonal Trust: From Modelling to Fostering Trust Through Design
(University of Waterloo, 2014-05-15)Trust is a core construct of our social lives, influencing how we interact with other individuals that are part of our social circle. Whether at work, in teams, or with friends and family, trust influences how much information ... -
The Use of Temperature and Environmental Isotopes as Tools to Characterize Groundwater Discharge to the Grand River, Ontario, Canada
(University of Waterloo, 2013-01-25)The Grand River Watershed, in southern Ontario, is home to approximately 900,000 people and one of the fastest growing regions in Canada; specifically, in the urban areas of Guelph, Cambridge, Kitchener, and Waterloo. ... -
The Use of the Internet in Distributing Packaged Software
(University of Waterloo, 2006)To reflect common practice in the software industry and extend transaction cost theory, this research developed building on previous research and empirically tested a model based on to identify conditions in which software ... -
Use of the interRAI Acute Care Assessment Instrument to Predict Adverse Outcomes Among the Hospitalized Elderly
(University of Waterloo, 2010-09-01)Abstract Objectives: This research project was undertaken to review two commonly used screening instruments for the elderly who attend at hospital emergency departments in Ontario. These instruments were then contrasted ... -
A Use of the Theory of Planned Behaviour to Determine the Social Barriers to the Implementation of Stormwater Green Infrastructure on Private Properties in Dundas, Hamilton, Ontario
(University of Waterloo, 2017-12-22)Climate change has resulted in more extreme rainfall events and most municipalities’ stormwater infrastructure is not prepared to deal with the increased flooding instances that may be associated with the increased rainfall. ... -
The Use of Traditional Environmental Knowledge to Assess the Impact of Climate Change on Subsistence Fishing in the James Bay Region, Ontario, Canada
(University of Waterloo, 2010-05-21)This thesis used traditional environmental knowledge (TEK) to assess the impacts of climate change on food security for First Nations communities located in the western James Bay region of northern Ontario. In addition, ... -
Use of Water Isotope Tracers to Characterize the Hydrology of Prairie Wetlands in Alberta
(University of Waterloo, 2018-01-22)Our understanding of prairie wetland hydrology comes primarily from a handful of long-term research stations, but generalizing from a few intensively monitored areas to the entire prairie pothole region requires assumptions ... -
Use of water isotope tracers to elucidate hydrological conditions of lakes in the Peace-Athabasca Delta over space and time: A foundation for lake ecosystem monitoring
(University of Waterloo, 2022-01-17)Hydrological monitoring in complex, dynamic northern floodplain landscapes is challenging but increasingly important as these ecosystems come under threat from multiple stressors, including climate-driven decline in ... -
Use-Bounded Strong Reducibilities
(University of Waterloo, 2009-08-20)We study the degree structures of the strong reducibilities $(\leq_{ibT})$ and $(\leq_{cl})$, as well as $(\leq_{rK})$ and $(\leq_{wtt})$. We show that any noncomputable c.e. set is part of a uniformly c.e. copy of ... -
User Interface Design and Validation for the Automated Rehabilitation System
(University of Waterloo, 2015-10-27)In current physical rehabilitation protocols, patients typically perform exercises with intermittent feedback or guidance following the initial demonstrations from the physiotherapist. Although many patient-centered systems ... -
A User-Centric Approach to Improve the Quality of UML-like Modelling Tools and Reduce the Efforts of Modelling
(University of Waterloo, 2020-01-28)As software systems grow in size and complexity, their development and maintenance are becoming increasingly challenging. Model-Driven Engineering (MDE) has been proposed as a means to increase the developer's productivity ... -
User-Controlled Computations in Untrusted Computing Environments
(University of Waterloo, 2019-01-15)Computing infrastructures are challenging and expensive to maintain. This led to the growth of cloud computing with users renting computing resources from centralized cloud providers. There is also a recent promise in ... -
User-Defined Gestures with Physical Props in Virtual Reality
(University of Waterloo, 2020-09-01)When building virtual reality (VR) environments, designers use physical props to improve immersion and realism. However, people may want to perform actions that would not be supported by physical objects, for example, ... -
A User-level, Reliable and Reconfigurable Transport Layer Protocol
(University of Waterloo, 2009-08-20)Over the past 15 years, the Internet has proven itself to be one of the most influential inventions that humankind has ever conceived. The success of the Internet can be largely attributed to its stability and ease of ... -
User-specific explanations of AI systems attuned to psychological profiles: a user study
(University of Waterloo, 2023-05-24)In this thesis, we design a model aimed at supporting user-specific explanations from AI systems and present the results of a user study conducted to determine whether the algorithms used to attune the output to the user ... -
Users, Queries, and Bad Abandonment in Web Search
(University of Waterloo, 2021-11-18)After a user submits a query and receives a list of search results, the user may abandon their query without clicking on any of the search results. A bad query abandonment is when a searcher abandons the SERP because they ... -
