Woven fabric-reinforced polymers (WFRP) are composite materials consisting of interwoven fibers dispersed in a continuous polymeric matrix phase. Lightweight and yet very strong mechanical characteristics of WFRPs are, however, often disadvantaged by poor quality due to manufacturing defects. The proposed project aims to exploit the simulation tools developed at University of Bristol to simulate the […]

La production de l’énergie électrique nécessite des actuateurs mécaniques de grande puissance. Au Canada, la puissance mécanique provient principalement des turbines hydrauliques activées par les rivières. Cependant, dans plusieurs pays, elle provient des turbines thermiques qui utilisent de la vapeur générée par des centrales à combustibles fossiles ou nucléaires. En Amérique du Nord, plusieurs de […]

Over 70% of tasks in manufacturing are still manual and because of this over 75% of the variation in manufacturing comes from human beings. Human errors were the major driver behind the $22.1 billion in vehicle recalls in 2016. Currently when plant operators want to gain an understanding of their manual processes, they send out […]

Les systèmes de production d’énergie basés sur l’utilisation de la force hydraulique utilisent une machine synchrone afin de convertir l’énergie mécanique en énergie électrique. Pour que ces machines fonctionnent, il faut fournir une puissance d’excitation sur la partie tournante de la machine (que l’on nomme système d’excitation.) Ce système d’excitation peut produire des courants électriques […]

Surface degradation during Oil & Gas and Mining operations in the Province of Alberta are pervasive. This has resulted in extensive research and development activities into the development of advanced surface modifications that are based on overlays and coatings. Most research effort has focused on materials selection, fabrication, and optimization of wear performance of those […]

The focus of my research is modelling graphene-hBN (graphene-hexagonal-boron nitride), a novel two-dimensional ceramic with the ability to allow for the measurement of both plastic and elastic strain. Mixing graphene with hBN augments the properties of the ceramic by making it stronger and more versatile. When exposed to an elastic strain, the ceramic will exhibit […]

Aircraft painting processes are very complex and involves several working stages. Besides, several highly skilled workers are required to work in a polluted environment for long periods of time. The automation of these processes would result in several benefits for both workers and companies. This project proposes the automation of aircraft painting processes using autonomous […]

Les sources de production d’énergie font appel à des éléments d’électronique de puissance permettant une gestion de l’énergie électrique produite. Il peut s’agir par exemple de convertisseurs transformant une tension alternative en tension continue, ou inversement. Ils servent de plus à définir correctement les caractéristiques électriques (tension et courant) mises en oeuvre dans les réseaux […]

In the operation of CANDU reactors, the Zr-2.5Nb pressure tubes holding the cooling water and fuel bundles are susceptible to hydride cracking-induced crack initiation mechanisms, known as delayed hydride cracking and overload crack initiation. For structural integrity evaluation of CANDU pressure tubes, of fracture toughness and hydride crack initiation models were developed. However, the hydride […]

A two-year study on brazing technologies used for sintered tungsten carbide tiles is proposed to address the following technical objectives: 1) brazing metallurgy for sintered tungsten carbide and substrate high strength steel, 2) adherence mechanisms between different braze compositions and carbide tiles, 3) brazing parameters for optimized brazed joint performance, and 4) the mechanical stresses […]

Thermal management of power electronic devices in an electric vehicle inverter is a critical factor influencing cost, size, efficiency and reliability of the system. Liquid cooling is a viable option; however, for peak power operation, the existing liquid cooling system must be optimized. A new impinging-jet-based liquid cooling system with enhanced heat transfer was designed […]
