The main objective of this project is to investigate the performance of LiN-cryogenic technologY, as well as, high pressure cooling (HPC) in turning of hard-to-cut aerospace materials. The performance of cryogenic machining and HPC will be compared to flood coolant to establish the optimum conditions for each cooling technique, in terms of material removal rate, […]

Typiquement, les matériaux utilisés dans les composites ne sont pas recyclables. Lorsqu’une pièce est brisée ou qu’elle atteint sa fin de vie, elle peut être brulée afin de récupérer les fibres de renforts, mais plus souvent les pièces se dirigent directement vers un site d’enfouissement. Nous travaillons depuis environ 10 ans sur une méthode de […]

L’objectif du stage de recherche proposé est de poursuivre un travail de thèse portant sur la caractérisation des déformations d’un matériau testé en compression. Pour exploiter des essais de compression et en déduite les propriétés mécaniques d’un matériau, l’hypothèse de la déformation homogène du matériau est faite. Or, la déformation est hétérogène à cause de […]

The past decade has revolutionized the astronomical observation of black holes. In 2015, the gravitational waves generated by the merger of two black holes were detected, which confirmed the predictions of general relativity and led to a Nobel prize. In 2019, an array of telescopes spread across the globe took the first image of a […]

Gravitational lensing occurs when a massive object, such as a galaxy cluster, bends the fabric of spacetime, turning it into a magnifying glass that focuses the light from a distant object behind it. This phenomenon allows astronomers to observe faint astronomical objects and some of the earliest faraway galaxies or black holes that would otherwise […]

The development of lunar rovers requires research in terramechanics to understand the interactions between wheels and loose terrain. While extensive terramechanics research has been conducted on Earth, few studies have focused on adapting these findings to the Moon’s different gravity environment. This project will focus on the Granular Scaling Law (GSL), a recently utilized mechanical […]

Molybdenum disulfide (MoS2) has been utilized as a space lubricant due to its suitability for vacuum environments. While MoS2 lubricants were adequate for early spacecraft, the increasing duration of missions has heightened the demands on these lubricants, necessitating ultrahigh wear lives extending from months to decades. To overcome these limitations, MoS2 has been co-deposited with […]

Lors des missions spatiales, les astronautes perdent souvent du muscle en raison de la microgravité, ce qui pourrait être aggravé par une balance énergétique négative, c’est-à-dire consommer moins de calories que celles dépensées. Pour les prochaines missions, les agences spatiales considèrent la gestion de cette balance comme essentielle. Cependant, peu d’études ont exploré comment l’exercice, […]

We will investigate a decision procedure for the monitorability of timed-properties of software controlled systems. A property defines a behaviour that a system is expected to exhibit, or in some cases, to not exhibit. In Runtime Verification, a property is monitorable if it is possible to construct a monitor that can detect the system’s conformance […]

This project focuses on improving the component quality after Laser Beam Machining (LBM) for HS188 (AMS5608), a superalloy critical in aerospace and power generation due to its high strength and corrosion resistance. LBM often leaves a recast layer, a residue of resolidified molten material on the side edges, which weakens the material’s strength and corrosion […]

The “Drone-Based Search and Rescue (SAR) System in Dense Forests” project aims to transform SAR operations using a coordinated swarm of drones equipped with advanced computer vision and machine learning algorithms. These drones, launched from DJI dock stations and connected via Starlink satellite technology, will efficiently locate missing persons in densely forested areas. By processing […]

While OLED displays are now a relatively-mature technology, they have been almost exclusively targeting consumer electronics. As such, the ultimate goal of this ambitious collaboration will be to: Evaluate the technology and supply chain readiness of actual OLED and other emerging display technologies. Assess their potential for cockpit (critical) and cabin (passenger-level) aeronautics and train […]
