Approche empirique à la calibration d’un modèle d’élément finis d’une mine en roche dure sous l’effet d’un comportement viscoplastique

L’exploitation d’une mine souterraine est sujette à d’importantes contraintes: l’espace de travail réduit, la distance parfois très élevé au minerai et le besoin de renforcer ou de supporter le massif rocheux. C’est sur ce dernier point que porte la présente recherche. Le choix d’un support de terrain approprié repose avant tout sur la bonne compréhension des contraintes (forces) naturel agissant sur notre excavation et les propriétés de résistance de la roche.

Development of Cost-Effective Solutions for Energy Management in Smart Buildings

The proposed research aims at developing control strategies under the paradigm of Demand Response (DR) in the context of the Smart Grid in order to improve energy efficiency and to reduce operational cost in commercial buildings and communities. The emphasis will be put on consumer side energy management strategies that able to balance energy demand and supply and to reduce the overall operational cost while providing an enhanced performance.

Planification de la production à court terme à la mine Westwood

Le projet Westwood est une mine d’or situé à proximité de Rouyn-Noranda, en Abitibi-Témiscamingue. Le gisement à exploité est composé de plusieurs veines minces très étalées dans l’espace et à grande profondeur. Ces conditions font en sorte que beaucoup de travaux préparatoirs sont requis afin d’accéder aux zones minéralisées. Étant donné ces conditions particulières et la grandeur de l’exploitation, il est déjà facile de prévoir que la planification à court terme, ou opérationnelle, des activités sera un vrai casse-tête.

Effet de la teneur en carbone sur la résistance du métal de base CA6NM à la propagation des fissures de fatigue

Les turbines hydrauliques dans les barrages sont fabriquées en acier inoxydable martensitique. Cet acier contient du Chrome, du Nickel et moins de 0.06% de Carbone. Notre étude se concentrera sur trois types de cet acier avec différente teneur carbone. Afin de ne mettre en valeur que l’effet du carbone, on leur fait subir des traitements thermiques pour avoir la même microstructure. Par la suite on fait des essais de traction et de résilience pour les trois aciers suivie par des mesures fractographique pour expliquer l’effet de carbone sur les propriétés monotone du matériau.

Improving efficiency and safety in aviation industry using big data analytics

In aviation industry a large flow of data including thousands of parameters are registered by FDRs (Flight Data Recorders). The objective of this project is to use this big data to improve the efficiency and safety of flights. The data is collected and segmented from the raw datasets and then proper data cleaning methods are used to preprocess data. Then, by the help of analytical models we define a baseline for different registered parameters and compare individual flights against the baseline to detect anomalies.

CRIAQ MANU-404 : Additive Manufacturing

Bombardier Aerospace, Bell Helicopter Textron Canada Limited and Pratt & Whitney Canada have all initiated projects on Additive Manufacturing processes. Although applications are different, all companies are facing the same challenges including the lack of a mature certification path and a mature Canadian supply chain. In order to accelerate the maturation of this technology, we are proposing the first Canadian industryled R&D program on additive manufacturing (AM).

Multi-Fidelity Design Optimization of Hydro Turbine Runner Blades

From an energy production perspective, the mobile component of the turbine, the runner, plays a key role in the operation of a water turbine. In the present competitive situation of deregulated energy markets, there is a great demand for more efficient runners which can withstand severe operating conditions. Traditional trial-and-error runner design methods largely depend on the designers’ experience, and always need long design cycles.

Development of an image-guided navigation platform for an automated and MRI-compatible robotic needle guiding device for percutaneous procedures

Prostate cancer is the second most cancer related death in men, accounting for over 111 M$ yearly in Canada. Current prostate biopsy or therapy procedures such as transperineal brachytherapy use transrectal ultrasound guidance and  a  template to guide needles along parallel trajectories. However, pubic arch interference (PAI) with the implant path obstructs part of the prostate from being targeted by the  brachytherapy needles.

Aircraft optimization and sizing methodologies

The proposed research project concerns the development of optimization tools and sizing methodologies used to assess optimal structural airframe configurations and aerodynamic lines for given business cases. A PDF intern will be in charge of proposing improved optimization strategies, mainly related to composite material, and of adding specific capabilities inside the internally developed sizing tool (LibStress) with the aim to increase the reliability and accuracy of the optimization models.

Validation of Android-based NFC technologies as a Platform for Authentication Solutions

Today, a growing number of mobile devices come enabled with Near Field Communications (NFC) “out-of-the-box.” This has opened the door to an explosion of new possibilities for smartphones, such as those running on the Andriod platform. These new NFC capable Android devices could potentially replace RFID technologies, which are widely used in a variety of authentication applications, such as control access cards. However, it is unclear that all such cards can actually be “cloned” on the Android platform, which only offers a limited access to its NFC capabilities.
