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 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 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 ... -
Using Penalized Linear Discriminant Analysis and Normalized Difference Indices Derived from Landsat 8 Images to Classify Fruit-tree Crops in the Aconcagua Valley, Chile
(University of Waterloo, 2016-05-20)Accurate crop type maps are critical for yield estimation and agricultural practices in modern agriculture. A new approach is proposed in this thesis to improve the crop type classification accuracy, by creating a new ... -
Using pragmatism to overcome the perils of monetary valuation: Applying Deliberative Q-method to understand the value of stream ecosystems in Amman, Jordan
(University of Waterloo, 2020-04-16)Existing ecosystem service literature is predominated by valuation studies that narrowly ascribe to either positivist or constructionist worldviews; each subject to inherent limitations that make their operationalization ... -
Using Pyrene to Probe Interparticle Polymer Diffusion in a Latex Film
(University of Waterloo, 2015-12-16)Fluorescence has been used for many years as a powerful analytical tool to probe the formation of films from aqueous latex dispersions. Currently, the most widely used method is fluorescence resonance energy transfer (FRET), ... -
Using Random Digit Representation for Elliptic Curve Scalar Multiplication
(University of Waterloo, 2018-09-20)Elliptic Curve Cryptography (ECC) was introduced independently by Miller and Koblitz in 1986. Compared to the integer factorization based Rivest-Shamir-Adleman (RSA) cryptosystem, ECC provides shorter key length with the ... -
Using Rhetorical Figures and Shallow Attributes as a Metric of Intent in Text
(University of Waterloo, 2011-05-20)In this thesis we propose a novel metric of document intent evaluation based on the detection and classification of rhetorical figure. In doing so we dispel the notion that rhetoric lacks the structure and consistency ... -
Using Road Weather Information Systems (RWIS) to optimize the Scheduling of Load Restrictions on Northern Ontario's Low-Volume Highways
(University of Waterloo, 2007-09-18)Covering the Northern part of the Province, Ontario’s low-volume roads provide a link from remote resource areas to markets. Thus, preserving this transportation asset from the two main sources of pavement deterioration, ... -
Using Self-Affirmation to Persuade Male Engineers to Respect Female Engineers
(University of Waterloo, 2016-09-29)Women are underrepresented in Science, Math, Engineering and Technology (STEM). Due to negative stereotypes, females in these fields are often treated with less respect from their male peers. In this study, we compared a ... -
Using Shamir's Secret Sharing Scheme and Symmetric Key Encryption to Achieve Data Privacy in Databases
(University of Waterloo, 2016-09-01)The Internet has become an essential tool for communication and information access, and with growing demand, new challenges and usage continue to surface. A complimentary tool that came to exist in recent years is Cloud ... -
Using Social Topography to Understand the Active Mobility Networks (AMNs) of People with Disabilities (PWDs)
(University of Waterloo, 2014-02-11)This study explores the physical features in the urban setting that give rise to inequitable outcomes for people with disabilities (PWDs), in particular, those with mobility impairments. The objective is to identify the ... -
