Geovisual Analytics for Smart Cities: Designing and Developing a User Interface for an Immersive Environment

This proposal represents part of a doctoral thesis aimed at developing an interface for immersive environments, allowing for geovisual analyses targeted at smart cities, using digital twins to investigate flood-related data. The proper application of interface design in this environment enables an improved understanding and perception of emerging risks, which are crucial elements in flood risk management. For the 13 weeks of research, we propose planning, conducting, and analyzing interviews with Canadian users to identify the user profile in developed countries, aiming for a future comparison with the needs of users in middle-income countries. As a result, we expect to finalize the proposed research project with detailed documentation on the needs, functionalities, and specifications of users in this environment.

Stretchable Electronics for 6G Anomalous Reflectors

6G is the next generation of wireless network technologies. 6G signals are millimeter-waves, which are highly prone to blockage from obstacles such as trees or buildings. Due to this, behavior of the wireless environment is highly probabilistic and coverage holes can appear. This project aims to develop a reconfigurable intelligent surface (RIS) which has the potential to mitigate coverage holes and allow for the wireless environment to be more programmable by steering signals. The RIS being explored in this project is an elastic anomalous reflector which can be mechanically stretched to change the direction of beams reflected off the surface. This approach shows promise as it works for millimeter waves, has a fairly large steering range, and is low cost. This project explores optimizations to previous designs of the device in order to increase its beam steering range as well as its reflection efficiency.

This will benefit the Sanada Lab at Osaka University by furthering their progress in research on this RIS. This project will benefit the University of Toronto by bringing unique perspectives and knowledge on 6G technologies, RIS, and metamaterials that may help advance research in related areas.

Shifting perceptions of substance use in northwestern Ontario

The Northwestern Health Unit (NWHU) aims to address substance use issues prevalent in its catchment area by integrating two projects. Firstly, targeting high alcohol consumption rates, the initiative will require behavior change strategies to combat the normalization of alcohol use. By tailoring interventions to diverse subgroups, NWHU endeavors to shift cultural attitudes, thus reducing associated health risks. Secondly, addressing misconceptions surrounding harm reduction, particularly in the context of drug use prevalent in the region, the project seeks to educate staff, stakeholders, and the public. By promoting evidence-based interventions, NWHU aims to mitigate stigma and enhance support for harm reduction programs. This holistic approach aims to foster healthier behaviors and attitudes, ultimately improving community well-being.

Innovation dans l’entraînement sportif: optimisation de l’interface d’un simulateur de boxe en réalité virtuelle

Ce projet de recherche a pour but d’améliorer un simulateur de boxe en réalité virtuelle afin d’aider les athlètes de boxe canadiens à s’entraîner de manière plus performante tout en réduisant les risques de blessures, telles que les commotions cérébrales. Le stagiaire sera responsable de l’évaluation de l’interface utilisateur du simulateur, en établissant une étude scientifique visant à comprendre l’expérience d’utilisation par des athlètes de haut niveau, des entraîneurs et des non-athlètes. En se fondant sur les retours des utilisateurs, le stagiaire proposera des suggestions d’améliorations pour rendre l’interface plus conviviale et mieux adaptée aux besoins de chacun.
L’organisme partenaire, l’Institut national du sport du Québec (INS Québec), bénéficiera de ces améliorations puisqu’il aura accès à un nouvel outil d’entraînement novateur qui répondra aux besoins des athlètes professionnels de boxe. Ainsi, il sera possible d’offrir une méthode d’entraînement plus sécuritaire, plus performante et plus efficace que les méthodes de boxe traditionnelles. En développant une solution qui améliore la performance des athlètes de boxe canadienne, l’INS Québec contribuera à accroître la visibilité et la réputation de la boxe canadienne sur la scène mondiale. Cela pourrait mener à davantage de succès sportifs et à plus de médailles.

Explainable time-series machine learning using the tsfresh module

The central idea of this project is the observation that publications using systematic time series feature extraction from the Open Source machine learning library tsfresh, always need to visualize and explain the extracted features. Due to the fact that tsfresh uses 168 algorithms to compute up to 800 time series features, this process can be highly automated using an object oriented approach. This project will contribute towards the development of a Python module for explainable time-series machine learning, which will assists researchers and engineers in the interpretation of their time-series based machine learning models.

Work order Scheduling at maintenance Sites for Commercial Aircraft Fleet

The effective planning of resources when scheduling maintenance tasks and repair jobs is an enormous challenge, especially for heavy industries such as aerospace and transportation manufacturers. In such industries, because of the product complexity and variety, not to mention continuous technological improvements, a broad range of maintenance tasks and high-performance services should be done over the course of a year to guarantee the safety and reliability of the products. The main contribution of the project is to address an important gap in the current theoretical methodologies and market software packages: the lack of an integrated tool to manage the resources in a maintenance site of the commercial aircraft fleets.

Caractérisation sous choc de foudre d’une nouvelle méthode de mise à la terre (MALT) basées sur l’utilisation des géopolymères électriquement conducteurs développés à partir de résidus de production de l’aluminium.

Depuis maintenant plus trois (3) ans, un projet a été initié par Rio Tinto et l’UQAC dans le but de réduire les
résidus issus de la production de l’aluminium sachant que leur entreposage est de plus en plus problématique.
Une des solutions proposées est d’utiliser ces différents résidus pour développer des géopolymères
électriquement conducteurs (GEC). Le présent projet vise donc à développer une application concrète utilisant
une quantité importante de GEC dans le développement d’une nouvelle méthode de mise à la terre (MALT) dédiée
aux équipements des réseaux électriques. La méthode proposée, appelée EE-GEC, est basée sur le principe
d’électrodes (en acier) encastrées (EE) dans un géopolymère électriquement conducteur (GEC). La mise en place
ce nouveau système de MALT va ainsi permettre développer une économie circulaire en permettant de réduire
significativement les résidus de bauxites et en offrant une alternative à l’utilisation du cuivre bientôt considéré
comme un matériau critique.

Advancing Dissolvable Fertilizer

Dissolvable Fertilizers are an agricultural innovation with slow and controlled fertilizer release. This technology is posed to reduce application costs and lead to optimized nutrient uptake by plants. Furthermore, it promises to reduce the agricultural, carbon footprint, as the frequency and amount of fertilizer applied is decreased resulting in less environmental pollution from nutrient loss. Excess nitrates and phosphates is leading national governments calling for the reduction in fertilizer use by 20 to 30%. However, the growing global population demands increased food production that is made possible through fertilizers. This project supports the development of dissolvable or glass fertilizer products. Sample compositions and plant growth on canola and/or select cereal crops will be assessed. The results will advance further development and customization of fertilize for improved nutrient ratios and dissolution rates for various crops and climates. The goal of the research outcome is to become commercially available to replace current, competitive fertilizers that do not solve greenhouse gas emissions, that are expensive, that tend to burn seedlings and that perform poorly in colder climates.

Simulation of viscoplastic fluid flows in superhydrophobic channels

The proposed project explores the flow dynamics of Bingham fluids through channels with superhydrophobic (SH) grooved walls. The focus is on understanding how these special surfaces, which trap air in grooves, affect the flow behavior of fluids that exhibit both solid-like and fluid-like properties under different stress levels. The research aims to develop a semi-analytical model alongside direct numerical simulations to investigate various flow regimes, especially how the flow transitions from creeping to inertial. The outcomes of this study could significantly benefit both participating institutions by advancing knowledge in fluid dynamics and potentially influencing the design of microfluidic devices and systems that use non-Newtonian fluids like blood or industrial pastes. This research is not only academically valuable but could also have practical implications in fields like biomedical engineering and materials science.

La production de quatre quarks top dans l’état final multilepton avec le détecteur ATLAS

La physique des particules se concentre sur l’étude des éléments fondamentaux constitutifs de la matière et des forces qui régissent leurs interactions. Les recherches dans ce domaine sont menées à l’aide d’accélérateurs de particules. De plus, le Modèle Standard de la physique des particules est le cadre théorique principal décrivant les interactions entre ces particules élémentaires, incorporant trois des quatre interactions fondamentales de la nature. Cependant, la gravité n’est pas pleinement intégrée dans ce modèle, le laissant encore incomplet.

Le stage proposé se déroulera au CERN en Suisse, dans le cadre de la Collaboration ATLAS au Large Hadron Collider, le plus grand et le plus puissant accélérateur de particules du monde. Le projet se concentre sur la mesure de la production de quatre quarks top dans l’état final multilepton dans des collisions proton-proton à une énergie de centre de masse de 13,6 TeV avec le détecteur ATLAS. Cette mesure rare peut fournir des informations cruciales sur les processus de production de particules et révéler de nouveaux phénomènes au-delà du Modèle Standard. Cette opportunité unique offre à une étudiante motivée la chance de contribuer à une recherche de pointe et d’améliorer notre compréhension des collisions de particules à haute énergie.
