EVOLUTION OF DEVELOPMENT AND GENE EXPRESSION IN DROSOPHILA
Evolutionary developmental biology (evo-devo) is the study of trait evolution through variation in development. As early as the modern synthesis, it was recognized that to an understanding of the function of genes during ... -
Characterization of the Biomechanical and Situational Aspects of High Magnitude Subconcussive Impacts in Canadian University Football
Background: Subconcussive impacts are asymptomatic head impacts that induce alterations in the brain after repetitive exposure. Understanding factors that lead to higher magnitude or frequency of subconcussive head impacts ... -
ARTIFICIAL NEURAL NETWORK BASED TRANSFER LEARNING FOR ROBOT KINEMATIC MODELLING
This thesis discusses the feasibility of applying the transfer learning for modelling robot manipulators. Artificial neural network (ANN) is selected as the tool to conduct transfer learning. For data generation, two types ... -
The Dark Side of Helping: Escalation
(Queen's University, 2020)In the real world, employees may be presented with difficult tasks that could be tackled in multiple ways and with available resources. On top of this, with deadlines, few external resources, and other tasks that employees ... -
Detecting Lagrangian Coherent Structures in Realistic Experimental FLuid-Flow Data Sets
Detection of coherence in sparse Lagrangian particle tracking (LPT) data is a crucial step towards increasing our understanding in a vast number of biological, engineering and geophysical flows. This thesis explores two ... -
CONTEMPORARY MEASURES OF MENTAL HEALTH STATUS AND SCHOOL-BASED RELATIVE AGE EFFECTS IN CANADIAN ADOLESCENTS
This thesis is on the epidemiology of relative age effects and how they relate to the mental health status of young people. Contemporary measures of mental health are developed, and the association between school-based ... -
HIGH-DOSE WEEKLY CARFILZOMIB, CYCLOPHOSPHAMIDE, AND DEXAMETHASONE IN THE TREATMENT OF PATIENTS WITH RELAPSED AND REFRACTORY MULTIPLE MYELOMA – EXPLORING THE FINANCIAL COST AND RARE SIDE-EFFECTS
Multiple myeloma Multiple myeloma (MM) is a malignant disorder of clonal plasma cells based in the bone marrow that leads to devastating symptoms including renal failure, hypercalcemia, anemia, and fractures. Treatment ... -
Stable Leader-Follower Systems: A Passivity Perspective for Telerobotics and Vehicle Platooning
Advances in computing, more affordable hardware electronics, and reliable communications have led to development of cutting-edge robotic applications where two or more subsystems interact in a leader-follower arrangement ... -
The Application of Structure from Motion Photogrammetry to the Ontario Rockfall Hazard Rating System (RHRON)
Roadways are considered critical infrastructure in North America, however, many pass-through hazardous terrains, such as rock slopes. To better manage and prioritize rockfall mitigation measures on rock slopes, the Ontario ... -
CURATORIAL CONTESTATIONS: CHALLENGING INSTITUTIONAL MODES OF INCLUSION IN THE ARTS THROUGH CURATORIAL POSITION(S) AND PRACTICE(S)
In today’s climate of political unrest, art institutions and curators play increasingly important roles, serving (their) varied constituencies and cultural communities by creating meaningful points of contact with diverse ... -
Response of cladocerans to native and invasive invertebrate predators in Lake Simcoe, Canada
How populations respond to changing environmental conditions is critical to their survival. Organisms can respond adaptively to new environmental conditions, for example an invasive predator, by the expression of phenotypic ... -
The Application of Distributed Optical Sensing to Measure the Full-Field Strain Response of Uniaxial Compression Test Specimens
The uniaxial compressive strength (UCS) test is crucial in determining the strength and stiffness behaviour of intact rock and is frequently utilized by industry to determine project site characteristics. A fundamental ... -
FACTORS AFFECTING GCL SELF-HEALING AND ITS SUBSEQUENT HYDRAULIC PERFORMANCE
A number of researchers have studied GCLs’ self-healing capacity, however, most examined either regular holes or relatively benign hydrating/permeating fluids not representative of typical field applications. This thesis ... -
A Made-in-Muskoka Approach
(2021)The District of Muskoka is well known for being a part of Ontario's cottage country with over 650 freshwater lakes found within the upper-tier municipal boundaries. As shoreline development pressures increase, so does the ... -
Exploring Irish Women's Experiences of Social Climate Around Abortion After the Repeal of the Eighth Amendment
This study explores abortion activists’ experience of the shift in social climate around abortion in the context of the campaign to Repeal the Eighth Amendment, which previously prohibited abortion in Ireland. Abortion was ... -
Using fluorescence spectroscopy to measure the biodegradation of naphtha in Athabasca oil sands tailings ponds
This study used fluorescence spectroscopy and solid phase microextraction (SPME) to develop a time-efficient and cost-effective method to measure naphtha biodegradation in Athabasca Oil Sands Region mature fine tailings ... -
TRANSITION METAL CATALYZED CROSS-COUPLINGS OF ALKYL SULFONE ELECTROPHILES
Sulfones are an important class of organic molecules that can participate in a wide variety of synthetic transformations. For this reason, they have been described as chemical chameleons. While their use as Csp2 electrophiles ... -
On the extraction of path-dependent dynamics from recirculating pulsatile flows using optical and ultrasound imaging
Recirculation is present in nearly every fluid system, and often jeopardizes the system's primary function. This thesis is motivated by recirculation in the cardiovascular system and how it impacts disease. Developing ... -
On the Transient Response of Rotors and Autorotating Seeds in Gusty Flows
Low-inertia rotors are present in quadrotors, micro aerial vehicles, and small wind and tidal turbines, to name but a few examples. The common practice of modelling the unsteady behaviour of low-inertia rotors using ... -
Behavioral Modelling of the Transient and CdV/dt Induced Turn-on of a Hybrid High Power Switch Unit
The use of hybrid power switches is a practical and effective method of improving the performance of high power switching devices. An emerging strategy is to combine high power Si IGBTs with SiC MOSFETs to take advantage ...
