Modélisation de la vulnérabilité et risques de chutes de blocs pour les parois rocheuses naturelles et fabriquées

Le projet de recherche proposé sera effectué en collaboration avec Hydro-Québec et a pour objectif une meilleure compréhension des mécanismes à l’origine de l’instabilité des parois rocheuses par une analyse de quelques cas répertoriés dans le cadre du projet hydroélectrique de La Romaine.

Feasibility Study of Incineration of Municipal Solid Waste in Churchill

Churchill is experiencing different types of challenges. Because of the remoteness of this place, the communication and transportation systems are very costly and challenging. Managing municipal solid waste manage is another emerging problem for Churchill community. The current waste management system in the town of Churchill is very costly, and environmentally unfriendly. Town of Churchill is evaluating the viability of a more environmentally friendly and cost-effective solution for the future solid waste management for the community.

Improving Structural Integrity of Buried Pipelines under Ground Deformation using Special Geobuffer Blocks: Field Testing and Strain Monitoring

Steel pipelines as key Canadian infrastructure are often exposed to various geological and environmental conditions that cause defects such as cracks, dents, and gouges in the pipe wall, which can lead to pipe fracture in pipelines, compromising the entire pipeline's functionality and resulting in significant economic losses, environmental issues or even fatalities. There are several methods to predict the fracture capacity, including experimental testing, analytical approaches, and advanced numerical methods.

Circular Engineering for Building Adaptation and Material Reuse Planning

An integrated methodology and platform are proposed to improve decarbonization of existing buildings. Circular engineering concepts will be implemented to reduce construction waste, carbon emissions, and costs associated with renovation, retrofitting and adaptive reuse of existing buildings. Novel design methodologies and technologies are explored for optimizing design option generation using various spatial, environmental and economic factors simultaneously.

Assessing liquefaction of sandy soil: missing gaps (with Imperial Oil)

Oil sands tailings, a mixture of clay, sand, water and residual oil, is a by-product from the oil sands mining and extraction process in Alberta, Canada. This mixture is hydraulically transported and stored in engineered structures built with coarse sands separated from the oil sands tailings. The dimensions of these structures depend on the storage capacity retaining oil sands tailings. The structural integrity of these structures is governed by the strength of the coarse sands or their liquefaction potential.

Vibration Monitoring of the Mactaquac Dam

Mactaquac Generating Station, the largest hydroelectric power plant in the Maritime provinces, is located near the capital city of Fredericton, on the Saint John River. In the mid-1970s, concrete structures at Mactaquac began to show signs of distress due to Alkali-silica reaction (ASR), resulting in cracks and leakage. The goal of this research project is to develop a continuous ambient vibration monitoring and damage detection system for the intake structure of the Mactaquac dam.

Equivalent stress formulation for stress design of pipelines

This project aims to provide new stress-design equations based on the equivalent stress criterion for the design of pipelines. The first part of the project will evaluate the safety levels of the stress-design equations already existing in the design standards. The second part will focus on the proposal and calibration of the new stress-design equations that ensure an appropriate safety level for the designed pipelines. The new equations will be proposed to the CSA Z662 design technical subcommittee (TSC) which the primary supervisor is a member of.

Cooperative ramp control in mixed traffic environment - Year two

This research will develop a novel freeway control approach for the era of co-existence of connected and autonomous vehicles (CAVs) and human-driven vehicles (HDVs). Fully connected and autonomous vehicles can navigate roads without a human driver and connect and interact with other vehicles, roadside infrastructure, and their environment. It is anticipated that the technology will be made available to consumers in the very near future. However, generic market adaption and phasing out of the current vehicle fleet is likely to take years or even decades.

Estimation dynamique de l’état des lignes du réseau de transport électrique d’Hydro-Québec par des approches statistiques avancées.

Le conducteur est un élément critique d’une ligne de transport d’électricité. Il est sujet à la corrosion affectant significativement sa durée de vie. Hydro-Quebec surveille avec un vif interet l'etat de corrosion de ses 34 000 km de lignes haute tension et voudrait estimer dynamiquement l’état de cet actif majeur pour optimiser sa valeur d’un point de vue fiabiliste. En premier lieu, le projet consiste à effectuer une revue du phénomène de corrosion des conducteurs, ainsi que des données disponibles sur les essais accélérés de corrosion.

Achieving Circular Wastewater Management with Machine Learning

Effective wastewater treatment is essential to the health of the environment. When operating wastewater treatment plants, utilities must ensure that the treated water meets environmental regulations, while balancing competing needs to minimize the cost of running the plant against the maximizing resource recovery. Additionally, most wastewater treatment plants include a combination of physical, chemical, and biological processes, all of which are complex and which can change rapidly in response to changing conditions.
