Rational design of a material for rapid colorimetric Fe2+ detection
(Elsevier, 2016-10-05)We report on the rational design of a novel TiO2 based screen-printed material suitable for sensitive and selective detection of iron ions in water. This includes the synthesis and characterization of large mesoporous TiO2 ... -
Ray tracing large distributed datasets using ray caches
(2012-03-09)Many large scale simulations now produce datasets that are signi cantly larger than can typically be stored in memory on a visualization system. Visualization algorithms then become ine ective and stall since the data must ... -
Readiness for digital learning: examining self-reported and observed mobile competencies as steps toward more effective learner readiness assessment
(2017-04-01)This mixed-methods study explores a digital-competencies survey tool for probing the readiness of higher-education students for digital learning, in three steps. First, it develops a methodology for capturing and analysing ... -
Ready, Teacher One
(2021-08-01)This study examines how French First-language teachers responded to virtual reality (VR) professional development in 2021 in the province of Ontario. The teachers used higher-end VR Oculus Quest 2 systems in a digital, ... -
Real time safety verification in the process industry using fault semantic networks (FSN)
(2013-08-01)In the process industry, there are uncertainties associated with each variable, which might lead to process deviations and hazards. In order to accurately quantify the risks associated with these hazard scenarios, quantitative ... -
A real-time 12-lead electrocardiogram remote patient monitoring and analytics framework
(2022-10-01)This work presents XBeats: A machine learning-based framework for real-time electrocardiogram monitoring and analysis that uses edge computing and data analytics for early anomaly detection. The framework encompasses a ... -
The reality of virtual, augmented and mixed reality in K-12 education: a review of the literature
(2017-10-01)This paper provides a review of the existing literature specific to the use of augmented reality (AR), virtual reality (VR) and mixed reality (MR) technologies within K-12 educational environments. The review explores the ... -
Reasons for concussion under-reporting in varsity athletes: a mixed methods approach
(2016-06-01)Sport-related concussion is an increasing challenge for student-athletes, medical staff, and faculties to manage in post-secondary institutions. Delayed assessment and management leads to increased time away from class and ... -
Recidivism and treatment attrition among persons who sexually offend (PSOs): applying the integrated risk assessment and treatment system (IRATS)
(2020-09-01)The aim of this thesis was to investigate whether the Integrated Risk Assessment and Treatment System (IRATS; Looman & Abracen, 2013) can provide an explanatory framework for understanding persons who sexually offend (PSOs). ... -
Recommendations in visual analytics using emotions : a mixed-initiative interaction approach
(2018-07-01)The thesis demonstrates an idea for helping users in visual analytic tasks by investigating some critical steps required for providing recommendations. The proposed model uses mixed-initiative interaction approach by ... -
Reconsidering the 'new' penology: Risk management, dangerous and judicial decision-making.
(2013-07-01)As a result of the prevailing sense that ‘nothing works’ and the proliferation of risk oriented concerns in the criminal justice system, the current penal era has been characterized as a “new penology.” According to Malcolm ... -
