Using Machine Learning to Understand the Hydrologic Impacts of Permafrost Thaw-Driven Land Cover Change
(University of Waterloo, 2023-04-25)Discontinuous permafrost regions are experiencing a change in land cover distribution as a result of permafrost thaw. In wetlands interspersed with discontinuous permafrost, climate change is particularly problematic because ... -
Using Major Histocompatibility Genes Polymorphism to Identify Arctic Charr (Salvelinus alpinus) Populations
(University of Waterloo, 2008-01-18)Arctic charr is the most northerly distributed salmonid and the most abundant fish in high latitude postglacial lakes. Arctic charr lives in oligotrophic water bodies where it has been able to adapt and thrive due, in part, ... -
Using Media Consumption To Explain Political Identification and Behaviour and Perceptions of the News Media
(University of Waterloo, 2006)Using secondary data from Pew's Early January 2004 Political Communications Study this thesis explains political identification, the range of media sources that a person uses, perceptions of political party bias and political ... -
Using Mental Set to Change the Size of Posner's Attentional Spotlight: Implications for how Words are Processed in Visual Space
(University of Waterloo, 2010-01-05)The present thesis investigated how words are processed within the context of visual search. Both explicit and implicit measures were used to assess whether spatial attention is a prerequisite for words to undergo processing. ... -
Using Metagenomic Approaches to Determine Antimicrobial Resistance Diversity and Prevalence within Four Landfills
(University of Waterloo, 2023-08-21)Antibiotics are one of the many hazardous substances present in municipal solid waste (MSW) landfills. Antibiotics can contaminate the leachate generated in landfills, which poses a threat to human health as leachate ... -
Using Microsimulation to Estimate the Impact of Transportation Improvements and Operational Policy Changes on Travel Time Reliability
(University of Waterloo, 2017-01-16)Traditionally, traffic engineers have designed roadway networks and operational strategies to manage congestion and minimize delays during the peak demand period for some “average” or “typical” day. However, increasingly, ... -
Using Natural Language Processing to Detect Breast Cancer Recurrence in Clinical Notes: A Hierarchical Machine Learning Approach
(University of Waterloo, 2021-04-26)The vast amount of data amassed in the electronic health records (EHRs) creates needs and opportunities for automated extraction of information from EHRs using machine learning techniques. Natural language processing (NLP) ... -
Using network analysis to explore the effects of road network on traffic congestion and retail store sales
(University of Waterloo, 2017-04-21)The physical road system plays a critical role in environmental and city planning. In the context of retail store site-selection, measures of accessibility and the ease and willingness of consumers to shop at a store can ... -
Using Numerical Models for Managing Water Quality in Public Supply Wells
(University of Waterloo, 2013-08-30)Groundwater models can be useful tools to support decisions regarding the management of public water supply wells. Scientific progress and the availability of increasingly powerful computer resources provide a continuous ... -
Using numerics to explore the EPRL spinfoam amplitude
(University of Waterloo, 2020-08-25)The use of numerical methods in loop quantum gravity is still relatively untapped. Numerical methods are, however, a useful tool, and offer access to regimes that are as of yet inaccessible by analytical methods. This ... -
Using paleolimnology to assess influence of Peace River regulation on lakes along two transects in the northern portion of the Peace-Athabasca Delta
(University of Waterloo, 2022-08-18)The Peace-Athabasca Delta (PAD), northern Alberta, Canada, is an ecologically and culturally important floodplain where debate has persisted for more than 60 years about causes of water-level drawdown of its abundant, ... -
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 ... -
