CONCEPTION ET FABRICATION D’UN BANC D’ESSAI POUR UN RÉCOLTEUR D’ÉNERGIE PROVENANT DU ROTOR D’UN HÉLICOPTÈRE

La récolte d’énergie (“energy harvesting” ou “energy scavenging”) a connu une croissance importante au cours des dernières années. C’est le processus de récupération de l’énergie (voir Figure 1) des sources externes (solaire, thermique, éolienne, acoustique, mécanique/cinétique, etc.) et de conversion en électricité utile à petite échelle. Dans l’industrie aéronautique en particulier, la conversion d’énergie vibratoire […]

Improved Unsteady Aerodynamic InfluenceCoefficients

Currently Bombardier Aerospace uses the Doublet Lattice Method (DLM), incorporated into a structural solver, to perform aeroelastic calculations such as flutter. This method is able to provide very good results in the subsonic regime, but looses accuracy in the transonic regime due to the high non linearity of the flow. A methodology was developed where […]

Development of a data processing and machine learning pipeline using non-invasive diffuse reflectance spectroscopy eye imaging for Alzheimer disease screening

Alzheimer’s disease (AD) is a progressive neurodegenerative disease and is currently the most common cause of dementia, affecting approximately 50 million individuals worldwide. RetiSpec has developed a non-invasive, label-free retinal imager that can uniquely detect and quantify AD biomarkers – namely, signatures of A? aggregates. The combination of hyperspectral imaging and machine learning may be […]

Identification of high-frequency periodic acoustic fish tags with deep learning

Innovasea produces fish tags and receivers to track the presence and motion of fish and marine mammals while underwater. Fish tracking (acoustic telemetry) is used by researchers worldwide to determine the abundance and habits of marine life, make decisions about fishing seasons and allowed catches, and help protect marine mammals. Innovasea has developed a novel […]

Simulation of turbulent premixed flames

Combustion continues to be the major source of power for electricity, transportation, and material processing. Modem day combustion devices such as automobile engines rely on computer simulations for analysis and optimization of geometry or operating conditions. Combustion problems that are solved to perform such simulations are described by complex multi-scale non-linear mathematical equations that entail […]
