A Finite Element Framework for Non-linear Material Constitutive Modelling of Superalloy Additive Manufactured Parts

Due to its versatility, time and cost saving, additive manufacturing (AM) technology, and more specifically selective laser melting process (SLM), is replacing conventional manufacturing processes, particularly for producing complex geometry components. In this technology, the near net shape parts are incrementally built by fusing layers of powder material using an intensive heating source/ Structural stress […]

Rugged Silicon Photonic Transceiver

Rugged transceivers, which can sustain harsh environments, are in high demand in the applications such as telecommunications, avionics, and space. Vertical-cavity surface-emitting laser (VCSEL)-based transceivers have been a cost-effective approach to address the demand. However, the exponential growth in the data volume, push the technology toward higher speeds at longer reaches. Reflex Photonics has been […]

Detection of spacecraft maneuvers based on publicly available data

Detecting maneuvers is important to a number of operational needs, such as to ease tracking of active satellites, discern and forecast the regular activity of a satellite, and detect deviations from nominal maneuver patterns. Although data on the orbits of satellites are publicly available on the internet, their precision is low and uncertain, which makes […]

Development of a Novel Sustainable Adsorbent Unit for Indoor Air Purifiers

This project is with Airpura – a developer of indoor air purifiers. We plan to develop a prototype and upscale the technology of recyclable coated iron-oxide systems, incorporated in the design, from the laboratory-scale to final consumer product use. The newly introduced adsorbent system serves to increase the removal efficiency of the volatile pollutants less […]

Searching for Supernova Neutrinos in the nEXO Experiment

nEXO is a planned rare nuclear decay search in xenon-136. The experiment will tell us whether the neutrino, somewhat like a charge-less and extremely light electron, and its antiparticle are identical. However, nEXO has extremely low backgrounds and thus is sensitive to a lot more than just decays in xenon-136. Core-collapse supernovae are stellar explosions […]

A Combined Theoretical and Experimental Study of Heterojunction Photocatalysis

Heterojunction Photocatalysis is currently considered as one of the promising routes to produce eco-friendly hydrogen fuel by exploiting the solar energy. The idea is based on the conversion of the solar energy to perform fuel-producing (e.g., hydrogen) electrochemical reaction that can split water into its ingredients. This technology has the potential to provide scalable, non-toxic […]

Development of Machining Strategies for Low Machinability Powder Metallurgy Ni-Alloys

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 […]

Impact zootechnique, économique et génique de l’âge au sevrage des caprins

Même si une forte croissance de la production laitière caprine au Canada est observée au cours des 20 dernières années, la productivité des fermes laitières caprines dépend de plusieurs facteurs liés à la génétique et à la régie de troupeau. La nutrition des chevrettes laitières et des méthodes d’élevage des chevrettes ont été identifiées comme […]
