Recherche de traceurs chimiques dans l’huile isolante permettant de déterminer indirectement la vie résiduelle des transformateurs de puissance

Un problème réel dans l’industrie des transformateurs de puissance est le manque d’outils et de méthodes précises pour déterminer l’état et la durée de vie de l’isolation principale. Ces appareils onéreux, composés d’enroulement de cuivre isolés par du papier et le tout baignant dans une huile isolante, représentent le coeur de tous réseaux électriques. Le […]

Shear-induced coalescence for controlling emulsion stability

To reduce the negative impact on the environment and increase the competitiveness of Canada’s oil resources in the global economy it is essential to improve the ability to separate crude oil from water. This proposal aims to advance the understanding of a novel mechanism to do this by studying individual oil and water droplets. The […]

Dynamic multi-type multi-priority emergency surgery scheduling with accurate service duration estimation

The process of setting surgical schedules in a modern hospital operating room suite is complicated. Scheduling surgery involves coordinating two separate but inter-related service distribution channels, namely, elective surgery operations and emergency surgery operations. Elective surgical cases are selected from a broad range of diagnostic categories and are scheduled in advance into surgical time that […]

Co-Ordination of Steel Production Operationsfor Increased Throughput

This project aims to improve the throughput of the production system at ArcelorMittal through better coordination between the production operations. The project proposes a sophisticated discrete-event simulation model to analyze the impact of all important parameters of the production system, such as steel temperature, furnace heat duration, ladle movements, and heat loss at ladle. Several […]

Economic and technical feasibility assessment of decarbonizing British Columbia’s building, transport and industrial sectors with electrification and power-to-gas transitions

This project investigates substitution of fossil fuels with electricity from renewable sources for the purpose of reducing greenhouse gas emissions in British Columbia. Burning natural gas, gasoline, diesel and other petroleum products heats our buildings, drives out cars, and powers our industries. Electricity generated from hydro, wind, and solar power can provide those same services, […]

Development of a UV-LED air purifier for indoor air

Indoor air is contaminated by a variety of chemical and microbial contaminants. These contaminants can be effectively removed or inactivated using a process known as photocatalysis. In this method, a photocatalyst is chemically activated using ultraviolet (UV) radiation and readily degrade the contaminants when coming in contact with them. The application of newly emerged ultraviolet […]

Prioritization and Optimization of the Sewer Flushing Program for Municipal Wastewater Collection Systems

The objective of the study is to develop an algorithm to streamline and automate the decision making process for implementing the municipal wastewater collection flushing program. Traditionally, a municipal flushing program, or pipe cleaning, is based on a time-cycle approach. This means that all sewer pipes in the network are treated the same, ignoring variables, […]

Effects of Switching Dynamics on Solvent Recovery Efficiency from Shrinking Polymer Microdroplets

Latex particles are widely applied in inkjet printing, painting, coating, lubrication and many other areas. The current process for latex production relies on emulsion formation and separation, requiring the use of organic solvents that are flammable and volatile with negative environmental impact. In their seminal work, Jessop et al reported switchable solvents that can be […]
