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.
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.
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.
The production capacity of the Kraft process is one of the important measures in the pulp and paper industry. A promising method for increasing the production capacity of the Kraft process is to lower the load of the recovery boiler by means of extracting lignin from the black liquor (BL).
An integrated biorefinery for furfural production is an opportunity for Kraft pulp mills to create value from hemicellulose, a class of wood component that is currently burnt for energy. Furfural is one of the top bio-products with the potential to replace many industrial organic compounds that are currently produced from crude oil revenue. The objective of this work is to develop an optimized biorefinery process that can be best integrated into a Kraft pulp mill.
High demands for fossil fuels and increasing concerns over global warming have renewed the interests in bio-butanol production from biomass resources as an alternative liquid fuel. Hemicellulose, as an inexpensive and abundant raw material, has great potential for being suitable fermentation substrate.
The research proposal introduced is a development of a systematic method for evaluating the performance of Kraft process equipments from the point of 'view of energy, water and chemicals, using new and adapted key performance indicators. The objectives are (i) to develop new Key Performance Indicators adapted to the Kraft process operations and equipments to evaluate their performance regarding energy, chemicals and water utilization, (ii) to propose process improvement projects and validate their practicality with the mill engineers.
Integrated lignin biorefineries present opportunities to increase the profitability of Kraft pulp mills through the diversification of product portfolio and improved sustainability. The purpose of this work is to develop optimized lignin biorefinery designs, which would be integrated into a Kraft pulp mill. A methodology combining process simulation, analysis and synthesis is proposed to achieve the purpose. Lignin acid precipitation process will be optimized in terms of chemical usage and yield and will be integrated into Kraft process.
MDA Montreal possesses a niche expertise on a wide variety of high-performance satellite telecommunication antennas. These antennas are exposed to extremely harsh environments. Some panels require a rigid mechanical assembly (i.e., nut and bolt fastening) but must preserve their thermal isolation for the proper operation of the antennas and to limit heat exchange towards the spacecraft. Relatively thick thermal shims or washers are currently inserted into these assemblies to almost completely block the heat flow between the two structures.
Dam failures may lead to catastrophic consequences, extending far beyond the immediate neighbourhood of the dam site due to sudden reservoir release or overtopping. The main objectives of this research project are: (i) to apply state-of-the-art simulation tools to investigate the seismic response of a real dam in Québec to formulate guidelines on the significance of including the effects of the irregularity of dam-rock interface and vertical component of earthquakes in the evaluation of the seismic response of dams.
