The project is centered around the need for procedures in classical relativistic field theories. The idea is to determine the minimal amount of rules (postulates) such that a classical field theory can be uniquely determined. More specifically, determining a set of rules such that a unique set of models will follow from Noether’s theorem. The […]

Consider the temperature distribution in a classroom; to change it, we need to install a heater somewhere in the classroom. With a heater, we can raise the temperature, as well as change its distribution such that less heat flows to doors and windows, and more to seats. The location of the heater in the room […]

We seek to test the behaviour of candidate detectors for the proposed CASTOR space telescope. We are focused on the response to dim images, the behaviour when resetting portions of an image during exposure, and the behaviour when using multiple reads throughout an exposure to reduce the effect of random noise generated when reading the […]

Tout au long de l’histoire de l’humanité le progrès scientifique et technique a été un moteur de notre évolution comme espèce. Ce progrès pousse l’humain constamment à reconsidérer ses propres limites tant du point de vue physique que cognitif. Bien que les conséquences des actions erronées des humains soient connues depuis l’antiquité, industrie 4.0 mène […]

Nickel based alloys manufactured via powder metallurgy (PM) are the next generation of materials that offer great service performance and increased efficiency of gas turbine engines. This class of material is characterized by their poor machinability. Additionally, limited information is known about the integrity of machined surfaces; thus limiting its acceptance by the industry. This […]

Les logiciels actuels de DHM (Digital Human Modeling ou d’ergonomie virtuelle) destinés à la conception de situations de travail et de produits demeurent difficiles à utiliser ce qui en limite grandement l’utilisation par les concepteurs et les ergonomes. Pourtant, l’utilisation plus répandue de DHM permettrait d’en arriver à des environnements de travail plus sécuritaires et […]

The ability for an autonomous robot to create its own map based on onboard sensors and simultaneously, localize itself within this map is know as Simultaneous Localization and Mapping (SLAM). Although the theory behind SLAM has been well developed much work still needs to be done in realizing SLAM solutions that meet situation-specific real-world requirements. […]

The degradation in performance and operating envelope of aero-engines with age and during critical transient operating conditions such as take-off is a well-known phenomenon. It is mainly caused by the increase in size of the tiny gap between the tip of the compressor rotor blades and the shroud, called tip clearance, from wear and/or shroud […]

This project involves developing novel methods for improving the estimation of surface displacement of natural earth surfaces using Synthetic Aperture Radar Interferometry (InSAR). The developed methods improve the precision that can be obtained when analyzing a series of sequentially acquired images over the same area. The methods also improve the robustness of the estimation in […]

Aero-engines are lightweight structures which are assembled of several thin walled cylindrical components (casings). Casings are joined by bolted flanges, and must withstand high forces. To accurately predict the response of casings assembly, the non-linear behavior of the casing joints must be considered. Currently, aero-engine manufacturers (i.e PWC) are facing serious limitations in matching the […]
