Development of Novel Graphene-modified High Performance Concrete Materials

Cementitious composites having superior mechanical strength and durability are always desirable in practical applications. To satisfy the multi-faceted need for future structural applications, it is critical to develop the materials that exhibit enhanced mechanical and durability performance in a sustainable way. Over the past decade, considerable research effort was focused on high performance construction materials using nanomaterials like Carbon Nanotubes (CNTs), Graphene Oxide (GO) and other strength modifiers.

Green technology to develop graphene oxide (GO) from forestry waste to remediate waste streams

This green technology is beneficial for Canada to mitigate environmental pollution as well as to find renewable resources to replace the exhaustible and expensive materials to develop composites, supercapacitors and nanomaterials for a secure supply of bioenergy as well as for environmental applications.

A computer vison-based method to recognize material transported by dump trucks

In the construction industry monitoring activities is important in order to evaluate the level of productivity or detect flaws in processes. Thanks to the advancement of methods based on artificial-intelligence such as computer vision, some activities concerning progress monitoring, quality control, and material flow tracking can be automated. In this project, computer vision methods are going to be employed in order to detect dump trucks during earthmoving work and identify the type of excavated material that are in it.

Evaluation of the effects of pipe-soil interaction on the stress based design of buried pipelines using advanced numerical modeling - Year two

Thermal stress analysis of the buried pipeline is an integral part of pipeline design and integrity analysis. Pipeline design code (e.g. CSA Z662) provides guidance on the thermal stress analysis of restrained and unrestrained pipe sections. However, a buried pipeline bend is more likely to be partially restrained, as the pipe is free to expand longitudinally, but the expansion is restrained by the pipe-soil interaction. No clear guidance is provided in the design code for a partially restrained condition.

Investigation comparative pour déterminer les aspects ayant un impact sur le comportement à la fatigue du conducteur alu-acier Bersfort monté avec une pince de suspension semi-rigide

Ce projet étudie les aspects mécaniques qui influencent le comportement en fatigue d'un conducteur alu-acier Bersfort monté avec une pince élastomère. En ce sens, l'étude réalise une comparaison entre les niveaux de contrainte des brins critiques du conducteur Bersfort lorsqu'il est installé avec des pinces métalliques et élastomériques pendant les vibrations induites par le vent. Cette comparaison est effectuée expérimentalement, à l'aide de jauges de contrainte, et numériquement, à l'aide de modèles par éléments finis des deux configurations d'assemblage.

A computer vision approach for identifying missing welds on prefabricated steel elements

Traditional time-consuming and error-prone methods of quality control of prefabricated elements can be replaced with state-of-the-art approaches. For example, emerging computer vision and deep learning technologies can be employed in the processes to achieve better performance and quality. To detect defaults and missing welds on prefabricated steel products in real-time, this study enhances the performance, robustness, and extensibility of the computer vision-based method previously proposed by our research team.

Introduction de l’intelligence artificielle à l’usine pour une réduction des émissions carbone associées à la production du béton

La réduction des émissions CO2 reliées à la production du béton est un défi important pour l’industrie. Le programme de recherche présenté vise à intégrer l’intelligence artificielle dans la production du béton. À terme, une usine « intelligente » pourra utiliser chacun des constituants du béton à son plein potentiel par une optimisation de la production en fonction de critères techniques, économiques et environnementaux.

Real-Time Control of Integrated Stormwater Systems using a Model Predictive Control Approach

Burdened by aging infrastructures, urbanisation and climate change, municipalities are seeking innovative solutions to address urban water management. To mitigate flooding, riverbank erosion as well as stormwater-caused pollution, many authorities are now relying on green infrastructures and intelligent flow control instead of the traditional grey infrastructures (e.g., basins and pipes).

Analysis of concentrically loaded braced frame using continuous end plate

The project consists in developing a design procedure for beam-column-bracing connection using welded end plates. This type of connection is simpler to fabricate, however, at present, the design standards do not specifically provide for their design calculations.

Teneurs en métaux dans les liquides de cigarettes électroniques et détermination de leur potentiel oxydatif

Les laboratoires Vaporus, une compagnie québécoise reconnue dans le marché des e-liquides et détentrice d’une certification ISO 9001 :2015, possède un strict contrôle de qualité sur les e-liquides qu’elle fabrique et commercialise. Cependant, la compagnie n’a aucun contrôle sur la fabrication des cigarettes électroniques qui se trouvent sur le marché et voudrait savoir si les atomiseurs de ces dernieres affectent la qualité des e-liquides.
