  • Nov 2021: Philippe and Jonas just published a great paper on the vibrational deformation of alpine skis in-use. The key message is that skis don't vibrate through separate bending and torsion modes, contrary to common knowledge, but through mixed modes. This is the first time this is measured in-use. This happens as the motion of a ski is constrained by one of its edge by the snow. Understanding how skis move is key to develop better products. We also present a new miniature data acquisition system to measure the in-use deformation, a simulation model that reproduce the observed behaviours and a new "robotic" testbed that can be used to evaluate the vibration response of skis on ice skating rinks to speed up product development. Follow this link to take a look at it.
  • Sep 2021: Branching Out Again with Remote Controlled Canopy Sampling: Good job to the DeLeaves' team for a successful sampling campaign with Neon.

  • Sep 2021: Sooth Ski just launched the most advanced alpine ski comparator & selector. This comparison tool was developed at the University of Sherbrooke and includes measured data from 3000+ skis! Using the online application, you can easily compare the geometry (e.g., rocker height/length, effective length, camber, surface, sidecut), bending and torsional stiffnesses (i.e., flex and twist resistance) and mass of different models/lengths to choose the best skis for you.
  • Nov 2020: Saws on drones: the latest tools in forest research Desbiens points out that there should be more back and forth feedback and open communications between scientists and engineers. “There are a lot of bright young engineers who want to help with conservation and are great at building technologies. We want to help improve how science is done by building innovative devices. If you have different tools you will think differently and that’s what’s exciting about this project.”

  • Juin 2020: Quatre doctorantes et un doctorant de l’UdeS parmi les meilleurs au monde: Bravo Hughes pour cette bourse Vanier (150,000$)! Le projet de Hughes La Vigne, qui s’effectuera en partenariat avec le National Tropical Botanical Garden, à Hawaï, vise à développer un prototype pour récolter des échantillons d’espèces sur les falaises de l’île afin de faciliter leur repopulation. L’outil favorisera la préservation de la biodiversité tout en offrant aux scientifiques l’occasion de développer des projets de recherche autrefois inimaginables.
  • Juin 2020: Bravo aux nouveaux étudiants boursiers d'excellence du CRSNG, FRQNT et IRSST: John Bass, Philippe Gosselin, Marc-Antoine, Guillaume Charron, Hughes La Vigne et Alexandre St-Jean. J'ai hâte de réaliser tout ces beaux projets.
  • Nov 2019: Radio-Canada: Dessine-moi un dimanche - Trouver la paire de skis parfaite: « Il n'y a pas de mauvais skis, mais il s'agit de trouver les bons skis adaptés pour chacun », dit le chroniqueur Jean-Luc Brassard. Celui-ci est allé à la rencontre d'Alexis Lussier Desbiens, professeur au Département de génie mécanique de l'Université de Sherbrooke, qui a mis au point une machine testant les propriétés d'un ski sans le faire glisser sur la neige.
