    Deformation Correlations and Machine Learning: Microstructural inference and crystal plasticity predictions

    The present thesis makes a connection between spatially resolved strain correlations and material processing history. Such correlations can be used to infer and classify prior deformation history of a sample at various strain levels with the use of Machine Learning approaches. A simple and concrete example of uniaxially compressed crystalline thin films of various sizes, generated by two-dimensional discrete dislocation plasticity simulations is examined. At the nanoscale, thin films exhibit yield-strength size effects with noisy mechanical responses which create an interesting challenge for the application of Machine Learning techniques. Moreover, this thesis demonstrates the prediction of the average mechanical responses of thin films based on the classified prior deformation history and discusses the possible ramifications for modelling crystal plasticity behavior in extreme settings

    Haida Nation and Taku River: A Commentary On Aboriginal Consultation and Reconciliation

    On November 18, 2004 the Supreme Court of Canada ( the Court ) released its two landmark decisions on aboriginal consultation. Haida Nation v. British Columbia (Minister of Forests) and Weyerhaeuser Company Limited, and Taku River Tlingit First Nation v. British Columbia (Project Assessment Director), together, provide the most significant discussion to date by the Court on Aboriginal consultation. The main issue before the Court was very narrow: did the governments have an obligation to consult Aboriginal peoples over government authorized activities in instances where the Aboriginal rights were unknown, uncertain, or in dispute, and if so the extent of that obligation. The Supreme Court of Canada concluded that where the Crown, federal or provincial, has “knowledge, real or constructive,” of the potential existence of an Aboriginal right, title or a treaty right, and contemplates conduct that might adversely affect that right or title, the honour of the Crown requires the Crown to consult and in some circumstances accommodate that interest. Ria Tzimas offers an overview of the two cases, discusses the m with reference to the analysis offered by Slattery and McNeil and discusses some thoughts on were the discussion concerning aboriginal consultation and reconciliation is likely to go and what the future challenges might be

    Huge Interatrial Septal Aneurysm: A Coincidental but Rather Fatal Finding

    Get PDF
    We report the case of a patient with a huge interatrial septal aneurysm as an intraoperative coincidental finding that led to a fatal outcome. The patient was admitted to our hospital in order to undergo elective coronary artery bypass grafting because he suffered from severe coronary artery disease. We intraoperatively diagnosed by transesophageal echocardiography a huge interatrial septal aneurysm mimicking a right atrial tumor. The aneurysm was initially resected and then coronary artery bypass grafting was successfully performed but the patient never achieved a successful separation from cardiopulmonary bypass probably because of massive embolic events
