In practical machine learning problems, it is important to understand impact of features on models’ predictions. Such an understanding helps not only better explain the black-box machine learning models but also enables their effective applications in business environment. The general model explanation approaches make an untenable assumption that the model’s features are uncorrelated, which can […]

L’entreprise Hortau a mis au point une nouvelle technologie mesurant directement le potentiel matriciel du sol sur une plage étendue allant jusqu’à -1000 kPa. Cette technologie a permis de caractériser de nombreux phénomènes en physique et hydrodynamique qui n’avaient encore jamais été observés. En testant différentes approches pour mesurer la tension du sol, l’objectif du […]

En 2010, au Québec, 73 % des terrains recensés par le Système de gestion des terrains contaminés (Système GTC), affichent une contamination de nature organique (Hébert et Bernard, 2013) Actuellement, les techniques de dégradation chimique et/ou biologique sont largement utilisés dans l’industrie, mais les résultats sont souvent décevants pour les hydrocarbures les plus lourds (Bunker […]

Product lifecycle management has always been promising. But achieving fully connected data, people, and processes may seem daunting for most SMEs. Spiri Robotics is a vibrant company with strong software engineering roots. They run distributed, remote operation in parallel in several North American cities using state-of-the-art versioning, testing and deployment tools for their code. However, […]

Parkinson’s disease (PD) is a devastating neurodegenerative disease impacting the nervous system and resulting in a wide range of symptoms including characteristic motor impairments such as tremor, slowed movement and muscle rigidity. It is an age-related disease affecting 1% of the population over the age of 60. Although symptomatic treatments are available, there are no […]

De nombreux problèmes décisionnels réels issus des domaines des transports, de la logistique et de l’administration publique partagent une structure commune dans laquelle un décideur cherche à adopter des politiques permettant d’optimiser un objectif qui dépend de la réaction d’une population. Pour adéquatement formaliser ce type de problème, l’hétérogénéité des préférences et des objectifs des […]

Reducing greenhouse gas emissions, particularly carbon dioxide, is a major scientific concern to tackle climate change. One promising method is to convert CO2 into fuels via electrochemical CO2 reduction (ECR). Nonetheless, several challenges remain before this technology can be scaled up and commercialized, including achieving a high selectivity, current density (i.e., reaction rate), and long-term […]

Decomposition is the dynamic process whereby a compound is disintegrated into its elementary constituents through physical, chemical and biological mechanisms. Matrices associated with decomposing human remains, such as soil, are an omnipresent source of physical evidence in forensic casework. Previous research has already emphazied the use of these matrices to evaluate their potential to capture […]

Probiotics could help prevent or treat metabolic-related conditions such as dyslipidemia or Type 2 Diabetes. Combination of probiotics with prebiotic fibers could potentiate the positive effect of these treatments. Our hypothesis is that probiotic strains, coupled with brown algae prebiotic fibers, may hold potential for modulating lipid metabolism, which might represent an interesting avenue for […]

Companies in the energy sector are increasingly considering the use of liquid metals in their operations (e.g. for cooling). This presents new challenges related to the inspection and monitoring of these infrastructures. Indeed, these industries often operate in very harsh environments (e.g. ionizing radiation) and under very high pressure and temperature conditions. Thus, the ultrasonic […]

The proposed consultancy services are going to conduct research related to the introduction of Automated Speed Enforcement (ASE) tools in a low-income African country (based on the Rwandan case study). Quantifying the effect of installing enforcement cameras on the number of damages, injuries, fatality collisions, and traffic offenses like speeding, crossing red lights, and talking […]

Le présent projet appartient au domaine de la représentation des connaissances et constitue un premier pas vers le développement d’outils informatiques en support au développement de dossiers de sécurité et d’audits de conformité reliés à la sécurité des TI. Il porte plus particulièrement sur la représentation formelle d’interprétations de requis de conformité reliés à la […]
