The focus of my research is modelling graphene-hBN (graphene-hexagonal-boron nitride), a novel two-dimensional ceramic with the ability to allow for the measurement of both plastic and elastic strain. Mixing graphene with hBN augments the properties of the ceramic by making it stronger and more versatile. When exposed to an elastic strain, the ceramic will exhibit […]

Aircraft painting processes are very complex and involves several working stages. Besides, several highly skilled workers are required to work in a polluted environment for long periods of time. The automation of these processes would result in several benefits for both workers and companies. This project proposes the automation of aircraft painting processes using autonomous […]

Les sources de production d’énergie font appel à des éléments d’électronique de puissance permettant une gestion de l’énergie électrique produite. Il peut s’agir par exemple de convertisseurs transformant une tension alternative en tension continue, ou inversement. Ils servent de plus à définir correctement les caractéristiques électriques (tension et courant) mises en oeuvre dans les réseaux […]

In the operation of CANDU reactors, the Zr-2.5Nb pressure tubes holding the cooling water and fuel bundles are susceptible to hydride cracking-induced crack initiation mechanisms, known as delayed hydride cracking and overload crack initiation. For structural integrity evaluation of CANDU pressure tubes, of fracture toughness and hydride crack initiation models were developed. However, the hydride […]

A two-year study on brazing technologies used for sintered tungsten carbide tiles is proposed to address the following technical objectives: 1) brazing metallurgy for sintered tungsten carbide and substrate high strength steel, 2) adherence mechanisms between different braze compositions and carbide tiles, 3) brazing parameters for optimized brazed joint performance, and 4) the mechanical stresses […]

Thermal management of power electronic devices in an electric vehicle inverter is a critical factor influencing cost, size, efficiency and reliability of the system. Liquid cooling is a viable option; however, for peak power operation, the existing liquid cooling system must be optimized. A new impinging-jet-based liquid cooling system with enhanced heat transfer was designed […]

La fabrication de pièces aérospatiales présente plusieurs défis importants, dont ceux du délai et du coût de réalisation. Dans le contexte économique d’aujourd’hui, `bien faire du premier coup` est impératif pour maintenir la compétitivité des entreprises. La recherche de l’efficience est alimentée par diverses opportunités provenant de technologies émergentes telles que l’assemblage par métrologie 3D, […]

Closed-loop control of nonlinear systems is typically performed by combining a number of linear controllers, each designed to perform well around an operating point. Although this solution generally works in many cases, there are some important practical applications, e.g. in diesel engine control or in robotics in which it fails and leads to serious performance […]

Aerosol deposition (AD) is a modification of low pressure cold spray technology which allows the deposit of ceramic based coatings. AD technology in a vacuum allows the formation of dense and well adhering ceramic films from sub-micro and nanoparticles directly at room temperature. The AD technology is still under development to cover more applications and […]

This project relates to the configuration of data generated by several robotic arms during the manufacture of an Airbus A350. Robots generate an enormous amount of data during these type of processes, and the data is crucial for future analysis of how to improve the process. In order to be analyzed, the data must first […]

Ce projet consiste à la mise au point de nouveaux procédés de fonctionnalisation par plasma du verre. À travers la synthèse d’un film mince, nous modifierons la surface du verre et étudierons les effets antibuée produits. Cette étude permettra de développer un procédé alternatif aux solutions existantes. La nature chimique du film mènera à une […]
