The use of natural gas as a fuel for on-road commercial vehicles offers significant benefits, including lower greenhouse gas emissions. Methane, the main component of natural gas, has many virtues as a fuel. However, its stability makes it harder to react in an engine. This introduces two challenges: first, an ignition source is needed to […]

Multi-phase aerated stirred fermenters are well-accepted in the production of biopharmaceuticals including antibodies and vaccines. Nevertheless, their hydrodynamic and mixing characteristics as well as the influence of various process engineering variables on their performance are not fully understood. In the current study, extensive experimentation (ERT and endoscopy) and the Computational Fluid Dynamics (CFD) approach will […]

A power-assisted wheelchair is a hybrid between manual and power wheelchairs that consists of an electric-assist system that can be easily mounted on a manual wheelchair. The market for power-assisted wheelchair systems has seen growth in the past decade because of their benefits on the health and mobility of manual wheelchairs users. However, current power-assisted […]

As one of the most cost-competitive forms of renewable energy, the wind has remarkable potential for fulfilling the increasing demand for global energy in an environmentally responsible way. Wind turbines in cold climate are becoming one of the most popular trends for wind energy developments. Because of highly variable operational conditions, wind turbines demand a […]

Slow pyrolysis is a process to convert biomass residues to valuable biochar products, which are used in agricultural, wastewater treatment, animal feed, carbon sequestration etc. IRSI focused on identifying optimal pathways for converting biomass into high quality biochar with maximum energy efficiency and minimal environmental degradation. This project focusses on modelling and simulation of a […]

Exonetik est une compagnie en démarrage qui développe une nouvelle technologie d’orthèse active qui permettra, entre autres choses, la réduction du coût métabolique lors de la marche. Cette nouvelle technologie sera bientôt testée sur des sujets humains, mais requiert encore du développement. En collaboration avec les ingénieur d’Exonetik, le stagiaire participera au développement de la […]

Le graphite naturel est un ingrédient essentiel pour la fabrication des piles Li-ion. Une pureté supérieure à 99,95 % est fortement souhaitée afin d’assurer l’efficacité à long terme des piles. Le graphite extrait des sites miniers contient des impuretés qui doivent être retirées avant de pouvoir être utilisé. Cependant, les techniques de purification actuelles nécessitent […]

Rapid prototyping, or 3D printing, has inspired the imagination of the general public, from simple build-it-yourself “hobby” machines using polymer-based binder material with inkjet functionality, to portable printers that can fashion components in zero gravity on the International Space Station. The functionality is user-friendly, in that printed material is dropped onto a substrate in viscous […]

The safe operation of a dam, such as Mactaquac, necessitates regular integrity monitoring over the structure lifespan. Optical fiber temperature sensing can provide seepage monitoring throughout a dam structure providing the operator with location specific seepage rates. Since the monitoring will be continuous over time and potentially operate over the lifespan of the dam operators […]

The proposed research project targets anomaly detection of event data. The project has a duration of four months and aims to achieve two objectives: (1) to evaluate the effectiveness of a novel approach on GAN for real-world data, and (2) compare it to alternative methods. The intern will use existing research resources, and will apply […]

The proposed research project targets computational performance improvements of an data analysis pipeline. The project has a duration of four months and aims to achieve two objectives: (1) to properly characterize the performance of individual stages of the existing data analysis pipeline in terms of execution time, memory, and I/O, and (2) to improve the […]

In warm climates, warm temperatures cause thermal stratification in hydropower reservoirs inhibiting mixing and leading to deoxygenation of waters at depth (hypolimnium). Turbines withdrawing water at depth result in low dissolved oxygen (DO) in the downstream flow having a large negative impact on the downstream riverine ecosystem. Legislation in the USA and elsewhere now requires […]
