Algorithms that learn and sample from probability distributions form an important part of machine learning, AI, and the natural sciences. One needn’t look far to find such algorithms at the bleeding edge of methodology, and in everyday scientific pursuit. The Wang-Landau algorithm is an example. It combines a sampling step with a learning step, to […]

Conventional agriculture needs large inputs of nutrients, through the addition of fertiliser, in order to produce the amount of food needed globally to sustain the population. Typical fertilisers are hugely wasteful, polluting the atmosphere and waterways, and affecting human health, wildlife, and ecosystem stability. Nanomaterials are very small particles that have potential to be used […]

Gasification of wastes (either urban waste or residues from forest and agricultural operations) at large scale is a challenging operation because of the heterogeneity of the feedstock. Enerkem has addressed such challenge via its state-of-the art Bubbling Fluidized Bed (BFB) technology coupled with secondary Cracking and Reforming that results in high conversion of Carbon to […]

The intern Samuel Valman will work with Professors André St-Hilaire and Normand Bergeron at IRNS to develop a system to monitor river water discharge using satellite earth observation. The method developed will focus on measuring discharge during the melt water season of rivers in Quebec. This meltwater period is traditionally the most difficult period to […]

La transition énergétique et le développement de nouvelles politiques en faveur du recyclage des matériaux dans les pays du Nord impliquent de nouveaux modèles de commerce des matériaux. En particulier, les régions qui importent des matériaux vierges pourraient passer au recyclage local, réduisant ainsi leurs importations. Ce remodelage initial des échanges de matériaux pourrait inciter […]

In order to accelerate the energy transition to a carbon-free economy, hydrogen is becoming increasingly important as an energy carrier. One way of producing green hydrogen is via water electrolysis using renewable energy. Strong governmental policies are being deployed around the world to support the implementation of the hydrogen infrastructure. However, the intermittent and fluctuating […]

This project extends my internship with the organization that began in May (another 4 month internship). My internship mandate from the start has been to support SeeChange in developing a DEI strategy based on the “best” practices in the literature. However, I have learned that there is mounting evidence proving that many DEI initiatives being […]

Insects, being dominant in almost all ecosystems, are vitally important for regulating ecosystem health. There are growing concerns that insect abundance is declining globally, causing serious consequences for ecosystem services. To understand insect abundance trends, and their drivers, we need long-term monitoring schemes that are sensitive enough to detect change over time whilst balancing against […]

My project proposes to analyze representations of the built environment in William McFarlane Notman’s photographs of the Royal Tour of Canada in 1901. Held at the McCord Museum in Montreal, the photographs picture the tour taken by the Duke and Duchess of Cornwall and York (later King George V and Queen Mary) across Canada on […]

La réalisation des travaux sur les infrastructures urbaines peut générer des nuisances qui affectent le bien-être et causent des pertes économiques aux citoyens. Afin de gérer ces impacts, il faut connaître leur nature et leur intensité, ce qui dépend, parmi d’autres facteurs, des caractéristiques du milieu environnant. Ce projet propose donc de classifier le milieu […]

Les systèmes de cueillette aléatoire robotisée (« 3D bin picking ») existent sur le marché depuis plus d’une décennie, mais sont toujours difficiles à configurer, lents, et très dispendieux. Avec les avances de la librairie libre de vision artificielle OpenCV et les caméras stéréo abordables, telles que OAK-D, le développement de systèmes de « 3D […]

Le Labo – Solutions Brassicoles est une entreprise qui produit à grande échelle des solutions de levures liquides à des fins brassicoles, c’est-à-dire qu’elle fournit aux microbrasseries du Québec, et bientôt d’ailleurs, les petites bêtes nécessaires à l’élaboration des bières, celles qui rendent possible la production d’alcool lors de l’étape qu’on appelle ‘fermentation’, mais permettent […]
