Développement d'un amortisseur multi-plages pour la suspension des motoneiges Ski-DooPizarro, Céline January 2013 (has links)
La nouvelle suspension des motoneiges Ski-Doo de l'entreprise Bombardier Produits Récréatifs (BRP), la R-motion, présente un amortisst~ur passif dimensionné pour un type spécifique de motoneige. L'objectif est maintenant de concevoir un amortisseur ajustable couvrant la vaste plage de fonctionnement de trois amortisseurs présents sur différents modèles de motoneiges et ainsi permettre à BRP d'avoir un seul amortisseur pour la famille de suspensions R-motion. Pour comprendre les phénomènes internes à l'origine de la force d'amortissement, la modélisation d'un amortisseur de référence a été effectuée en intégrant un nouveau modèle de déflexion de cales dans le modèle d'amortisseur de Talbott. Des essais expérimentaux effectués sur des empilements de cales de l'amortisseur de référenoe ont permis de corréler le modèle développé aux résultats expérimentaux. Par la suite, cette connaissance a été utilisée, pour simuler le comportement d'un prototype d'amortisseur ayant deux valves ajustables fournissant une plage d'amortissement en compression et une autre en détente. Une deuxième phase expérimentale a alors été réalisée. Elle a servi à valider l'architecture en série utilisée pour placer les valves dans le prototype, puis elle a permis de trouver la meilleure configuration de valves ajustables en compression et en détente pour répondre au cahier des charges.

Design, Prototyping and Testing of a Tool for Intracardiac Delivery and Anchoring of a Prosthetic MitraI ValveMarshall, Eli 25 April 2012 (has links)
The mitral valve in the heart sometimes struggles with diseases and complications, and needs to be replaced. This problem becomes more frequent with the ageing of the population in developed countries. The most common practice consists of suturing a prosthetic valve into place. However, newer methods are being devised and tested to make the surgery faster and less invasive. In particular, various types of new sutureless heart valve systems exist on the market. However, there is still a need for a tool designed for the intracardiac delivery and anchoring of a prosthetic mitral valve, as addressed here. A number of criteria and specifications were set by researchers at the Robarts Research Institute (London, ON) who came up with the design task. To address their request, ten conceptual designs of a sutureless, virtual-reality guided, self-anchoring, intracardiac system were developed to hold a prosthetic mitral valve, deliver it safely, and quickly affix it in position. The winning concept adequately met the design criteria. Two prototypes were manufactured. The attachment of a prosthetic valve to a simulated mitral valve annulus was tested with the first prototype to verify feasibility and measure leakage. The second prototype was pressure tested in a dynamic surgical phantom reproducing the circulatory conditions during surgery. While the preliminary feasibility of the concept was established, recommendations were made to develop a less bulky design.

Data based abnormality detectionPurwar, Yashasvi 06 1900 (has links)
Data based abnormality detection is a growing research field focussed on extracting information from feature rich data. They are considered to be non-intrusive and non-destructive in nature which gives them a clear advantage over conventional methods. In this study, we explore different streams of data based anomalies detection. We propose extension and revisions to existing valve stiction detection algorithm supported with industrial case study. We also explored the area of image analysis and proposed a complete solution for Malaria diagnosis. The proposed method is tested over images provided by pathology laboratory at Alberta Health Service. We also address the robustness and practicality of the solution proposed. / Process Control
