SAR Interferometric Time Series Methods for Monitoring Natural Surfaces

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 […]

ERGO4ALL: Validation d’un algorithme d’analyse des postures et applications de force

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 […]

Nonlinear Dynamic Analysis of Aero-Engines

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 […]

Validation and calibration of Squeeze Film Damper Model with Experiment

This research project studies a specific component in the commercial aircraft engine called the squeezed film damper, or SFD. The SFD is applied to reduce the vibration of the engine rotor, which in turn reduces the noise and brings comfort to the passengers. The expected delivery from this project includes an advanced SFD model which […]

System Controller – Connector/Harness/Baseplate Redesign Feasibility Study

Electronic assemblies are used to control various systems in an aircraft. Under normal operating conditions, these assemblies undergo vibration, and therefore have an expected life span. Different designs are analyzed to reduce production cost, and these designs have to ensure that the electronic components contained within the hardware can tolerate the same operating conditions without […]

Characterization and Design of Additively Manufactured Components for Predictability and Materials Integrity

Rapid prototyping, or 3D printing, has inspired the imagination of the general public, from simple build-it-yourself “hobby” machines using polymer-based binder material with inkjet functionality, to portable printers that can fashion components in zero gravity on the International Space Station. The functionality is user-friendly, in that printed material is dropped onto a substrate in viscous […]

3D RFM SLAM for UAVs Subject to Severe Vibration

The first step for any robot to achieve true autonomy is to create a map of its surroundings and localize itself within this map at the same time. This is popularly known as the Simultaneous Localization and Mapping (SLAM) problem. Although much theory has been developed over the years to solve the SLAM problem, researchers […]
