SBB désire changer de procédé de soudage pour un de leurs produits. Ils veulent remplacer 3 soudures présentement effectuées à l’arc électrique, par des soudures par friction malaxage (FSW). Le soudage par friction malaxage est un procédé relativement nouveau qui utilise la friction générée par un outil en rotation pour mélanger l’interface de deux pièces […]

This research project aims to identify the defects in large steel blocks and remove them by providing a practical solution which causes to optimize the machining operations and improve the product quality. The solution will be found using simulations instead of expensive, time-consuming experiments, which are impossible to conduct in large blocks to recognize the […]

Neuromorphic computing is an approach to artificial intelligence (AI) that uses hardware elements inspired by the components of the brain and presents an alternative to the dominant von Neumann computing paradigm based on digital hardware. Recently, nano-scale devices known as memristors have been identified to offer area- and energy-efficient solutions when used in neuromorphic computing […]

Data acquisition at scale implies missing values: in the biological signals as well as in the demographics and questionnaire data. These missing values are structured –missingness appears as blocks– and often causal –more missing health information for lower income individuals. While there are many works on the treatment of missing values in the clinical trial […]

Strong evidence for T cell activation in atopic dermatitis disease pathogenesis exists, as demonstrated by the clinical efficacy of therapeutic T cell cytokine blockade. The subsets of human T cells capable of contributing to pathology of this disease remain poorly defined, lending importance to the characterization of T cells and their cytokines within active skin […]

Similar to current efforts in the automotive industry, there is a substantial interest in developing fully autonomous trains. One of the key steps towards enabling autonomous operation is being able to accurately estimate train position and speed. In addition to this, better estimates will also increase safety and reduce distance between trains, allowing more frequent […]

Robust perception in all weather conditions is a critical requirement for autonomous vehicles. This project proposes fusing gated and conventional RGB camera images for robust scenes encoding, depth estimation and trajectory prediction. Conventional approaches using lidar and RGB camera fail to perform robustly in rain, fog and snow. By extending existing computer vision algorithms to […]

Most of the drugs used to treat cancer have been originally identified from natural sources. While Nature did a great job selecting those compounds, some of them have shown limitations in the treatment of cancer and others have shown to be insufficient on some cancer types. Furthermore, it exists a gigantic number (nearly infinite) of […]

APN in Quebec City faces a high fluctuation of the lifespan of tools in machining operations such as milling and turning. This hampers production planning, since the number of necessary tools for a job as well as their lifetime cannot be well predicted. Previous investigation on this challenge could not determine a reason for this […]

The goal is to create a conversation loop between 3D designers and artificial intelligence programs. This will help the AI provide suggestions to the designer, while the designer provides the AI with feedback. This can help make it easier for designing complicated objects as well as complicated textures that belong to the surface of 3D […]

Le projet consiste à concevoir des liens faibles intégrés dans les cordages des casiers à crabe des neiges pour permettre aux baleines noires qui s’y font piéger de se libérer d’elles-mêmes. Les liens faibles sont des maillons fragiles qui cèdent lorsque la baleine exerce une force quand il se sent pris dans les cordages. Ce […]

Les antibiotiques utilises de nos jours reposent en grande partie sur des architectures chimiques mises au point il y a plusieurs decennies. Le probleme de resistance aux antibiotiques crolt a un rythme alarmant, ce qui laisse presager que les antibiotiques courants pourraient bient6t devenir inefficaces. Notre equipe de recherche a recemment elabore une nouvelle famille […]
