Abstract: <p>Deep Neural Networks (DNNs) have reached human-level performance in numerous tasks in the domain of computer vision. DNNs are efficient for both classification and the more complex task of image segmentation. These networks are typically trained on thousands of images, which are often hand-labelled by domain experts. This bottleneck creates a promising research area: training accurate… more Full Text: Representation Learning with Restorative Autoencoders for Transfer Learning A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science …

Abstract: <p>Mafic and ultramafic mine wastes have the potential to sequester atmospheric carbon dioxide (CO2) through enhanced weathering and CO2 mineralization. In this study, kimberlite residues from South African diamond mines were investigated to understand how weathering of these wastes leads to the formation of secondary carbonate minerals, a stable sink for CO2. Residues from Venetia Diamond… more Full Text: ENHANCED WEATHERING AND CARBONATION OF KIMBERLITE RESIDUES FROM SOUTH AFRICAN DIAMOND MINES: IMPLICATIONS FOR CO2 SEQUESTRATION A thesis submitted to Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of …

Abstract: <p>The human cornea is required to exhibit specific material properties to maintain its regular shape under typical intraocular pressures which then allow for its correct optical functionality. In this thesis, the basis of continuum solid mechanics and the finite element method are introduced. We use finite element modelling to simulate the extension of an effective-1d, linear-elastic bar,… more Full Text: The Adoption of a Finite Element Model of Material Deformation Relevant to Studying Corneal Biomechanics A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty …

Abstract: <p>The Continuity Hypothesis states that dreams reflect waking day cognition and experiences, which reflect one's mental health status. As such, dreams are, by extension, cognitions that occur during sleep. To date, Cognitive Behavioural Therapy (CBT) is deemed the most efficacious method of social anxiety treatment by working with cognitions. The current study utilized both CBT and… more Full Text: IT’S ALL IN YOUR HEAD: COMPARING COGNITIVE BEHAVIOURAL THERAPY (CBT) AND THE STORYTELLING METHOD (TSM) OF DREAM INTERPRETATION FOR REDUCING SOCIAL ANXIETY LEVELS A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the …
