The primary role of the lubrication system of aero-engines is to remove the excess heat generated by the movement of the bearings, gears and shafts. An aircraft engine has bearing chambers to contain the oil used for lubrication and excess heat removal. Inefficient scavenging of the oil out of the bearing chamber can result in […]

Tailings dams are used to store water and waste that come as by-products from the mining process. They can be huge in size, as big as lakes, and reach 300 meters high. Tailings storage facilities can pose a threat to local wildlife and ecosystem, especially in the case of failure. In Canada, the Mount Polley […]

Additive manufacturing (AM), also known as metal 3D printing, can revolutionize the way we make things by ‘printing’ parts one layer at a time using a laser and metal powder. However, AM is an inherently expensive process. One of the major costs of the process is the metal powders, with some powders costing hundreds of […]

The project brings together Canadian industrial and academic partners. This project will allow Pi-Sol Technologies, our industrial partner to develop durable and cost-effective zinc anodes for sustainable energy applications such as Zin-Air batteries. The zinc-air battery market includes a large number of electronic gadgets and appliances used in day-to-day life, remote sensing & communication sector, […]

Le traitement du drainage minier (DM) est une activité clé pour la durabilité des opérations minières. Idéalement, un système de traitement passif devrait être conçu pour fonctionner pendant nombreuses années, sans nécessiter une maintenance majeure. Des études récentes ont montré l’efficacité de ce système pour les sites miniers abandonnés et éloignés en voie de restauration. […]

Per- and polyfluoroalkyl substances (PFAS) are a very large family of persistent anthropogenic chemicals utilized in the manufacturing of industrial materials with non-stick and oil/water repellent properties, Teflon, and fire-fighting foams. Their use has resulted in their final dispersion in soil, groundwater, and surface water, causing adverse environmental and health effects. They are responsible for […]

The proposed project aims to apply artificial intelligence methods to augment in-place non-destructive testing technologies in order to reduce or eliminate the need for intrusive methods (i.e. concrete core extraction) for concrete strength estimation. The proposed approach is based on the SonReb method, which combines two non-destructive testing technologies, namely ultrasonic pulse velocity and rebound […]

Robotic sensor networks (RSN) are increasingly applied to Critical Infrastructure Protection (CIP). In such an application, a RSN is deployed to safe-guard some critical infrastructure (e.g., building, pipeline, etc.) in a secure and reliable fashion. By actively considering risk as a major driving force, this project aims at deciding on the optimal configuration of an […]

The use of disposable face masks as preventive measures significantly increased in the past years. Overloading landfills with disposable face mask wastes will raise certain environmental concerns. However, their degradation in landfill leachate is poorly studied. The objective of this study is to investigate the degradation process of the mask in landfill leachate and quantify […]

The successful agronomic strategy relies on nutrient detection and estimation. Adequate management of nutrients is an important concern for the whole growth period of Potato (Solanum tuberosum L.) cultivation. In this work, we try to analyze the situation of potential harmful elements for potato production such as Aluminium (Al) and Manganese (Mn) in soil and […]

Route Optimization for Waste Collection vehicles at the City of Edmonton

Malgré le peu de considération portée aux impacts du gel en conception de chaussées rigides, il est connu qu’elles sont sensibles aux variations de température. Les gradients de température entre le haut et le bas des dalles font en sorte qu’il peut y avoir apparition de fissures transversales et de fissures aux coins (Harvey, 2004). […]
