Mathematical methods for 2D-3D cardiac image registration
(2016-12-01)We propose a mathematical formulation aimed at intensity-based slice-to-volume registration, aligning a cross-sectional slice of a 3D volume to a 2D image. The approach is flexible and can accommodate various regularization ... -
Mathematical modelling of the plunger pump operation with numerical methods for simulating the flow across the valve
(2011-12-01)Plunger pumps are needed for heavy duty sludge pumping at wastewater treatment facilities. America's leading pump manufacturer Wastecorp Inc. brought their plunger pump problem to us in late 2009. It was found that when ... -
A matrix-free numerical bifurcation method applied to sheared annular electroconvection
(2015-08-01)We investigate the flow transitions in sheared annular electroconvection using matrix-free numerical bifurcation methods. In particular, we study a model that simulates a liquid crystal film in the Smectic A phase suspended ... -
MAVIDS: an intelligent intrusion detection system for autonomous unmanned aerial vehicles
(2021-07-01)Unmanned Aerial Vehicles (UAVs) face a large threat landscape, being used in numerous industries in hostile environments while relying on wireless communication. As attacks against UAVs increase, an intelligent Intrusion ... -
Maximizing efficiency of solar energy harvesting systems supplying a microgrid using an embedded system
(2019-12-01)Due to the high initial capital cost of photovoltaic (PV) panels and their low conversion efficiency, it is imperative to operate the PV system at its maximum power point (MPP). In this context, the goal in this thesis is ... -
Mean girls in the press: a content analysis of two Toronto newspapers
(2011-10-01)Recent criminological scholarship characterizes media attention to aggressive girls, or “mean girls,” as a moral panic, which is correlated with the creation of increasingly punitive antibullying policies in North America. ... -
The meaning of murder: newspaper framing of hate crimes against lesbians.
(2014-08-01)The overall purpose of this study is to assess the representations of lesbians within United States news print media to examine the effect these representations can have on societal level ideologies. Using two separate ... -
Measuring cues to deception: a multitrait-multimethod analysis
(2021-12-01)Cognitive load and arousal are constructs typically included in theories of deception, but they are often measured using a range of unvalidated techniques. Using a multitrait-multimethod analysis, I assessed the reliability ... -
Measuring the effects of subclinical neck pain on sensorimotor integration using electroencephalography event related potentials and source localization
(2017-11-01)Subclinical neck pain (SCNP) is recurrent neck pain that has not yet been treated. This thesis investigated whether acute pain affects motor learning acquisition in SCNP vs. healthy individuals. 10 healthy and 10 SCNP ... -
Measuring Web 2.0 interaction: a meta-synthesis of literature on using transactional distance and social presence
(2015)In this study, the researcher created an instrument, based on a meta-synthesis of relevant literature, to measure the presence of the variables associated with Transactional Distance and Social Presence when used as a ... -
Mechanics of machining metal matrix composites: analytical modeling and finite element simulation
(2015-01-01)Metal matrix composites (MMCs) are commonly utilized materials in various industries, including applications in aerospace and automotive industries, due to their outstanding strength-to-weight ratio and wear resistance. ... -
Mechanisms by which exercise promotes cognitive function in both depressed and non-depressed individuals
(2017-12-01)Major depressive disorder (MDD) is a debilitating disease characterized by low mood, memory deficits, poor sleep quality and alterations in biochemical markers associated with neuroplasticity. Less than half of MDD patients ... -
Mechanisms by which exercise promotes hippocampal function in both depressed and non-depressed individuals: A feasibility study
(2012-08-01)Depression is one of the top ten health problems in the world, affecting millions of Canadians. Research indicates that exercise is an effective treatment for depression but it is not clear on exactly how and why it works. ... -
Metabifurcation analysis of a phenomenological ventricular cell model
(2018-08-01)Heart disease is the leading cause of death in America, and arrhythmia is considered one of the most important precursors of heart attacks. We cannot predict arrhythmia directly; however, it has been shown that cardiac ... -
Metabolic, neurotoxic and immunotoxic effects of PFAAs and their mixtures on the proteome of plasma and head kidney from rainbow trout
(2023-03-01)PFAAs (Perfluoroalkyl acids) are a class of bioaccumulative, persistent and ubiquitous aquatic contaminants. A paucity of toxicological information exists for short chain PFAAs and PFAA mixtures. In order to address these ... -
Metal-free methodology for the preparation of ynones using potassium alkynyltrifluoroborates and its application to the synthesis of natural products
(2015-03-01)A straightforward procedure for the preparation of ynones from potassium alkynyltrifluoroborate salts and acyl chlorides or anhydrides has been developed. The one-pot reaction is advantageous in that it does not require ... -
A method to detect and represent temporal patterns from time series data and its application for analysis of physiological data streams
(2020-03-01)In critical care, complex systems and sensors continuously monitor patients’ physiological features such as heart rate, respiratory rate thus generating significant amounts of data every second. This results to more than ... -
Methods for optimization of neutron detector performance in nuclear power plants
