Using metal frames for constructing residential buildings is gaining attention in North America. They would be advantageous over wood frames because: (1) metal has a higher strength-to-weight ratio, therefore, less framing would be required, (2) metal frames are lighter in weight than wood, so easier to carry them on site, and (3) they offer better […]

La transition énergétique mondiale nécessite le développement et le déploiement massif des énergies renouvelables, telles que les technologiques photovoltaïques. Les technologies photovoltaïques à base de matériaux pérovskites sont parmi les plus prometteuses pour les prochaines générations de modules photovoltaïques. Éventuellement combinées avec des cellules à base de silicium, des rendements de conversion photovoltaïques proches de […]

The main challenge in using polymers in outdoor application is to extend their life time and make them stable against sunlight. Recently, graphene has been suggested as a new type of polymer photo-stabilizer to replace toxic and harmful photo-stablizers commonly used. The main challenge is to understand protective mechanisms of its action. Is it a […]

The presence of chlorine-bearing compounds in sewer headspaces is a potential risk to personnel and can cause decay of valuable infrastructure through increased rates of corrosion. There is however little information available on their speciation and concentration in these systems as standard methods for sampling them from sewer headspaces do not exist. In addition, the […]

Corrosion of the reinforcing steel is an extensive problem that reduces the service life of the structure and results in costly repairs and safety hazards. As a result, such deteriorated concrete structures must be replaced or extensively repaired, rehabilitated or strengthened. As a result, engineers worldwide are continuously seeking durable materials and robust systems to […]

Le Centre vétérinaire DMV a été fondé en 1993, par un groupe de vétérinaires avant-gardistes. Leur objectif est d’offrir une gamme étendue de services d’urgence et de soins spécialisés, dans un centre hospitalier permanent. Au fil des ans, le Centre vétérinaire DMV n’a cessé d’investir dans de l’équipement de pointe afin de permettre à ses […]

The CookieBox is an angular streaking detector developed for LCLS-II which extracts intrinsic characteristics from an X-ray shot. Those characteristics can then be used to classify and determine if the X-ray shot respects the pre-established experimental framework. However, to be of any value to the rest of the experiment, this classification must be done quickly, […]

Virtual and mixed reality (VR/MR) systems have burgeoned over the last couple of years with applications in healthcare, gaming, telepresence, and skills training, to name a few. Within the skills training sector, for example, police/law enforcement training is an important application domain which has seen increased adoption worldwide. In Canada, Public Safety and the Royal […]

L’objectif de mon travail est d’améliorer l’efficacité globale du rendement énergétique dans le domaine de l’installation de l’entreprise Stace, spécialisée dans le CPV (Photovoltaïque à concentration). Pour ce faire, la solution retenue consiste à insérer un étage intermédiaire de conversion DC/DC entre les panneaux CPV (en configuration série) et l’onduleur branché à chaque tracker. L’idée […]

Au Québec, le secteur des arts du cirque a été fortement touché par la pandémie. Les industries du divertissement souhaitent créer des spectacles virtuels ou hybrides pour se réinventer. Pour ce faire, il est nécessaire de capture le mouvement des acrobates pour le retranscrire dans un environnement numérique, mais la technologie actuelle avec marqueurs sur […]

Credit card payments are one of the most common transaction methods in our daily life, such as online shopping, e-commerce, and mobile payment. However, with the extensive usage of credit cards, numerous credit card fraud transactions occur every year and cause a huge economic loss. In order to improve the detection performance, this project proposes […]

Sludge, a waste component of the paper making process, while typically placed in landfills, has the potential for a value-added end use in the capacity as a component in the hydroseeding process replacing the typical cellulosic shredded additive utilized to bind the hydroseed mixture and reduce movement once spread. The case study industry, Port Hawkesbury […]
