Soudage laser avancé sur extrusions d’aluminium

Le projet de recherche proposée porte sur l’amélioration du soudage laser de composantes en aluminium. Composantes qu’on peut retrouver dans des lignes d’assemblage automatisé de l’industrie du transport (automobile, ferroviaire ou aéronautique). Le perfectionnement et la précision micrométrique dans la réalisation de soudure au laser de qualité supérieure, permettront : d’améliorer la productivité de l’organisme […]

Characterization of a novel 3D-FML for submerged turbine application

The proposed research aims at increasing the efficacy of tidal turbines by incorporating light-weight and resilient blades into a currently used turbine. For that, a recently developed 3D fiber-metal-laminate (3D-FML) material at Dalhousie University will be used. In comparison to metals that are presently used to form blades, or potentially fiber-reinforced composites, the 3D-FML would […]

Improved Numerical Combustion Models for Predicting and Reducing Pollutant Emissions in Gas Turbine Engines

Gas turbine engines are the primary propulsion device for today’s aircraft. These engines operate on liquid hydrocarbon-based fuels and as such can yield a range of undesirable pollutants including gaseous emissions such as nitrogen oxides (NOx), carbon monoxide (CO), green-house gases (GHG, largely CO2, really a combustion product) and unburned hydrocarbons (UHC), as well as […]

Optical Variable Effects for Minting Applications

The appearance of polished gold and silver has always been attractive to the human eye. The high reflectivity of these surfaces naturally makes them strong candidates for optical designs that are based purely on reflective optics. When circular grooves are scribed into metal surfaces, some very interesting optical effects can be observed, and in some […]

Exploration of machine/deep learning techniques using Raman spectroscopy for the identification and classification of brain tumors and prostate cancer

Cancer cells are nearly impossible to distinguish from normal tissue without sophisticated detection methods and conventional methods fail to provide real-time information during the surgical procedure. ODS Medical is developing an exclusive Raman spectroscopy system that collects data through an optical probe and is interfaced with sophisticated machine learning algorithm to identify tissues abnormalities in […]

Efficient Face Recognition for Wearable Camera Devices

Titan Sécurité Inc. has deployed wearable video camera devices for security and surveillance applications, and seeks to accurately detect and recognize objects appearing in captured videos. This project focuses on video-based face recognition (FR), where facial trajectories captured with video cameras are compare against one (or few) reference stills for each individual of interest. The […]

Projection hydroclimatique de la teneur en eau des sols et des faibles débits en milieu forestier

Les changements climatiques vont intensifier les périodes de faibles débits et affecter les teneurs en eau dans les sols. Les projections de débits produites à ce jour sont cependant minées par des limitations importantes, notamment une estimation simpliste de l’évapotranspiration et une méconnaissance des propriétés des sols en milieu forestier. Ce projet propose d’intégrer une […]

Performance et optimisation de coagulants inorganiques préhydrolysés pour la production d’eau potable

Le projet vise à optimiser une filière de traitement fréquemment utilisée par les villes lors du traitement des eaux potables: la coagulation. Cette étape est essentielle à l’enlèvement de plusieurs contaminants organiques et inorganiques d’intérêt de santé publique. Kemira, le partenaire, bénéficiera de l’expertise du stagiaire et du superviseur en ce qui a trait à […]

Développement d’un outil de calcul du coût du cycle de vie de ponts routiers pour la Grappe industrielle AluQuébec

Ce projet de recherche vise à optimiser l’utilisation d’aluminium dans la conception de ponts routiers. Des recherches récentes montrent que l’aluminium pourrait présenter de nombreux avantages économiques grâce à son excellente durabilité, le peu d’entretien qu’il nécessite et son recyclage en fin de vie. Ces avantages seront tangibles dans la durée et non pas lors […]

Tribo-electrostatic Separation of Potash

Over two years a post-doctoral fellow will investigate the electrostatic separation of potash. This will be accomplished experimentally by triboelectrically charging different materials, with and without conditioning agents, and then testing different separation techniques. Separation techniques will include electrostatic separation and a fines removal process. Electrostatic separation implementation in Saskatchewan may have multiple advantages, when […]
