Estimation de la pose de la caméra physique en production virtuelle

Cette recherche explore l’intégration des espaces physique et virtuel en production cinématographique. L’espace physique regroupe acteurs, décors, éclairages et caméras, tandis que l’espace virtuel crée des environnements numériques immersifs. Pour un rendu visuel réaliste, les mouvements de la caméra physique doivent être précisément suivis et reproduits dans l’espace virtuel. Actuellement, ce suivi repose sur des marqueurs réfléchissants détectés par des caméras infrarouges, une solution complexe et coûteuse, sujette à des problèmes comme l’occlusion et des recalibrations fréquentes.

L’objectif de cette recherche est de concevoir un système novateur basé sur l’analyse en temps réel des indices de profondeur et de mouvement, capable de déterminer la pose de la caméra avec une précision millimétrique et une latence inférieure à 8 millisecondes. Cette approche éliminera le besoin d’infrastructures lourdes, rendant la production virtuelle plus accessible. En améliorant l’interaction entre les espaces physique et virtuel, ce projet ouvre la voie à des outils créatifs pour le cinéma, favorisant une synchronisation fluide et en temps réel entre les caméras physiques et les environnements numériques.

The project aims to identify sustainable nitrogen management practices that minimize emissions and enhance crop yields.

This collaboration between the University of Guelph (Canada) and Universidad Nacional de Mar del Plata (Argentina) bridges expertise in sustainable cropping systems and nitrogen management. By integrating datasets from diverse agroecosystems, the research generates actionable insights into reducing GHG emissions, improving nitrogen use efficiency, and fostering climate-resilient farming practices. The findings will benefit policymakers, researchers, and farmers globally, supporting the transition to sustainable agriculture.

Assessment of surgical tool inpainting techniques in epilepsy neurosurgery

Inpainting refers to the process of removing a foreground object from an image and seamlessly replacing it with consistent and contextually relevant background pixels. In the context of epilepsy neurosurgery, training videos are recorded using a microscope-mounted camera to document surgical procedures. However, surgical instruments frequently obstruct the camera’s line of sight, partially occluding brain tissue that is critical for assessing surgical techniques. This project aims to develop advanced inpainting techniques to remove surgical instruments from video recordings while preserving the anatomical integrity of the underlying brain structures. We will investigate state-of-the-art methods to ensure that the reconstructed regions maintain high visual fidelity without introducing distortions or artifacts. By integrating these techniques into our neurosurgery simulation platform, we aim to enhance the training and evaluation of surgical procedures. Additionally, this study will provide valuable insights into the feasibility of inpainting as a viable alternative within our current workflow, potentially improving the clarity and usability of surgical training videos.

The Assessment and Evaluation of Physical and Biochemical Measurements for Leading Indicators to Injury and Illness for Canadian Association of Petroleum Producing workers

The goal of this research project is to explore the current definition of obesity along with the association of body fat distribution and biochemical markers with serious health conditions. Our investigation will employ the utilization of the dual-energy x-ray absorptiometry (the current gold standard to measure body fat percentage, subcutaneous body fat and visceral body fat) to more accurately define obesity and its association with cardiometabolic risk factors. We will also explore the functional interaction of cardiometabolic risk factors and adipose tissue derived cytokines with adiposity and insulin resistance to improve the assessment of worker in isolated work environments. Lastly, from the physical and biochemical measurements we will create a health risk matrix to be implement as a tool to assess the improvement and/or deterioration in health status of the oil and gas workforce of Newfoundland and Labrador. This research project will look to improve upon the current definition/assessment of obesity and demonstrate the importance of body fat distribution regarding cardiovascular metabolic risk for oil and gas workers of Newfoundland and Labrador

Influence of plant chemical diversity on the insect herbivore

Aphids are one of the most destructive pests of agricultural and horticultural crops, damaging plants through their feeding and also by vectoring plant pathogens. In Canada, crop losses due to aphids and the pathogens they vector are significant and forecast to increase as global warming progresses and new aphid species become established with more generations expected during longer summers and lower mortality predicted due to milder winters. This research focuses on understanding how host plant chemical diversity affects two aphid species, the green peach aphid and the black bean aphid, and addresses important agricultural and ecological questions such as whether aphids preferentially feed on host ecotypes that are less chemically diverse, how this affects their performance and if aphids are able to sequester plant-derived compounds. This collaborative research project draws on expertise from both McGill University and the University of Bielefeld in plant chemical ecology, aphid biology and plant-insect interactions to understand how intraspecific chemodiversity shapes plant-insect interactions to provide fundamental insights into plant chemical ecology as well as critical information that may be applied in agriculture to optimize sustainable management practices.

Micro-compounding Techniques for Optimizing ecoFibre-Polymer Composites

FibeCycle is committed to advancing the recycling of EOL composite materials into high-value, sustainable products. By sourcing EOL wind turbine blades and other composite materials, FibeCycle’s ecoFibre offers a sustainable alternative to virgin glass fibers. However, the variability in the chemical and physical properties of these recycled fibers necessitates careful consideration of their compatibility with different polymers.
Rapid micro-compounding tests provide a powerful tool for efficiently exploring a wide range of formulations. These tests enable the evaluation of small batches of polymer composites, allowing for relatively rapid iteration and optimization. This approach not only reduces the time and cost associated with traditional compounding methods but also accelerates the identification of optimal formulations that maximize the mechanical properties of the resulting composite materials.

Investigating the role of probiotics in cell death and intestinalbarrier integrity

Our gastro-intestinal tract is colonized by billions of microorganisms that constitute the intestinal flora or microbiota. These microorganisms, primarily bacteria, are required for our development and physiology; however, changes in the “normal” composition of the microbiota, referred to as dysbiosis, have been linked to chronic inflammatory diseases in humans. Currently, a major research effort is to understand what these commensal bacteria are, how they maintain health, and how their dysregulation causes disease. Probiotic bacteria supplementation constitutes an attractive therapeutic strategy for inflammatory diseases and are investigated in this project to understand how they interact with intestinal epithelial cells to regulate barrier integrity. Our specific aim is to interrogate whether a probiotic combination, consisting of three commensal bacterial strains, maintains intestinal barrier function by modulation programmed cell death, specifically, an inflammatory form termed necroptosis. We aim to understand the triggers of intestinal epithelial cell death, how the probiotics regulate its induction and the consequences on inflammation and disease.

L’intention d’entreprendre en collectif chez les jeunes au Québec : Valeurs, motivations et dynamiques de l’économie sociale

Ce projet de recherche s’intéresse aux jeunes Québécois de 18 à 35 ans et à leur intérêt pour l’entrepreneuriat en économie sociale. Il vise à mieux comprendre leurs motivations, leurs valeurs et la dynamique collective qui les anime, tout en mettant en lumière ce qui distingue cette approche des modèles entrepreneuriaux plus individualistes.
L’entrepreneuriat collectif, fondé sur la solidarité et la participation, répond à des défis sociaux majeurs, notamment en région où son impact est structurant. Pourtant, il demeure peu représenté dans les politiques publiques et encore mal compris. Ce projet comblera ce manque en apportant des connaissances essentielles sur les aspirations des jeunes et en aidant le Chantier de l’économie sociale à développer des outils et programmes adaptés.
Les résultats attendus permettront de mieux soutenir les jeunes entrepreneurs collectifs et de valoriser ce modèle auprès des décideurs publics. À terme, cette initiative contribuera à renforcer l’économie sociale et à générer des retombées positives pour les jeunes, leurs communautés et l’ensemble du Canada

The R&D project focusing on ingredient extraction and subsequent product formulation

This project focuses on developing a natural ingredient from fruit waste to be used in an agricultural product called a biostimulant, which helps plants grow better. The intern(s) will first work on extracting this ingredient using a special process that ensures it has the right properties for the final product. Then, they will mix and test the biostimulant to check how well it dissolves and flows, which are important factors for its use in farming. The goal is to create a high-quality, easy-to-use product that can be applied to crops effectively.

The partner organization will benefit from this research by gaining a reliable and efficient method for making their biostimulant. This will help them bring a new, eco-friendly agricultural product to market, supporting sustainable farming practices. If successful, the project could lead to further development, commercialization, and wider adoption of the product, benefiting both the company and the farming industry.

Surface modification of Petcoke Activated Carbon for Removal of Recalcitrant Naphthenic Acids from Oil Sands Process Effected Waters

The oil sands industry in Alberta, Canada, generates large amounts of wastewater, known as oil sands process-affected water (OSPW), which contains high levels of toxic naphthenic acids (NAs). NAs, which can reach concentrations of up to 120 mg/L, are the main contributors to the water’s toxicity, posing significant risks to nearby ecosystems like the Athabasca River. This research seeks to develop a cost-effective remediation solution by using adsorbent activated carbon materials made from petroleum coke (petcoke), a waste by-product of oil sands extraction. While traditional petcoke-based activated carbon can absorb many contaminants, certain complex NAs are difficult to remove. The study aims to enhance these activated carbon adsorbents by chemically modifying them with amines, nitrogen-containing compounds that improve the capture of stubborn NAs. Various chemical methods will be explored to attach these amines to the carbon surface, and the modified materials will be tested to measure their effectiveness in removing NAs from OSPW. The goal is to create an affordable and scalable treatment process that can significantly reduce the environmental impact of OSPW, offering a sustainable solution to wastewater management in the oil sands industry.
