TV Whitespace (TVWS) designates the inactive or unused space between TV channels actively used in UHF and VHF spectrum :470 MHz to 700 MHz. The TVWS band performs best in the most rural service areas. This is due to the characteristics of TVWS, and how it’s shared with powerful analog TV stations Such TV transmitters […]

L’objectif de cette recherche est d’étudier et améliorer les performances d’un rotor de queue d’hélicoptère novateur. Le concept à l’étude fait usage de plusieurs hélices fixées sur des moteurs électriques pour générer une poussée. Ce concept se veut intéressant pour plusieurs raisons notamment la réduction des émissions sonores, la réduction de la consommation énergétique et […]

Oil sand tailings could take ages to naturally dewater enough to be reclaimed. Finding ways to accelerate dewatering fluid tailings is crucial to improving overall reclamation planning and performance. The goal of the proposed project is to establish a new thermoanalytical technique for quantification and analysis of free and bound water contents in both individual […]

Just as every computer needs a processor, every processor needs a cooling system. Without one, the significant heat generated by the processor will overheat the system. As time has advanced, this heating issue has only become more critical, thus necessitating the advent of more effective cooling solutions. Microgaps, which pass coolant through, as the name […]

Artificial Intelligence (AI) is transforming our lives in the same way as the advent of the Internet and cellular phones has done. However, it takes thousands of CPUs and GPUs, and many weeks to train the neural networks in AI hardware. Traditional CPUs, GPUs, and brain-inspired electronics will not be powerful enough to train the […]

Shape memory alloys are materials which, when cooled are easily stretched, but when heated, return to its previously “remembered” shape with a high force. This allows for a simple heat engine to be made, which can use hot and cold sources to create motion and do work. The amount of work that can be done […]

Currently, the service provided by GRAD4 has an interface for visualization of CAD models. However, there is still room for improvement in speed and comprehensibility for the users: both manufacturers and buyers. The main challenge of implementing the improvements is in relatively high computational cost of such visualizations: while a regular PC handles such task […]

In recent years, automation has become more accessible to small- and medium-sized businesses, leading to an increase in popularity of ultra-compact and easy-to-integrate industrial robot arms like Mecademic’s Meca500. However, because of their size constraints, it is harder for these robots to accurately follow a programmed path. This research project aims to improve the path-tracking […]

Underground mining operations are very energy intensive and could require significant use of fossil fuel burning on site for electrification and heat provision, if situated in off-grid areas. Conventionally, these power plants employ diesel gen-sets that can convert only about 35% of the combustion energy to qualified work and discard about 65% of the energy […]

Les nouvelles technologies émergentes dans la construction, notamment celles liées au BIM et aux simulations 4D à 7D, créent une rupture dans les méthodes de gestion et entrainent des changements majeurs dans la manière de gérer, coordonner, modéliser et planifier les chantiers, de même que la communication des informations. Cependant, lors de la planification, les […]

Le Canada est un important producteur de cuivre et de zinc. Ces deux métaux sont exploités pratiquement en continu depuis les années 1950 dans le Camp Minier de Matagami en Abitibi. Le district a produit près de 5 millions de tonnes de zinc à l’aide d’une douzaine de gisements appelés « amas sulfurés ». Ces […]

Brine water is often produced in mineral extracting processes. It can cause damage to soil and biota when being spilled during storage and transportation. The damage can last for decades. Even after a mineral extracting process is closed, the damage of soil structure and composition would still not be recovered. The long-lasting devastation may cause […]
