Modélisation et Optimisation d’un Système de Stockage d’Énergie Thermique à Haute Efficacité

L’utilisation d’énergies renouvelables est nécessaire pour limiter les émissions de gaz à effets de serre ainsi que le réchauffement climatique. Le stockage d’énergie est un secteur d’ingénierie et de recherche indispensable à la mise en place d’énergies renouvelables en grande quantité, car l’apport de ces énergies est intermittent et n’est pas en phase avec la consommation d’énergie mondiale. Pour cela, Sigma Energy Storage a développé une solution hybride de stockage d’énergie thermique et mécanique. L’objectif de ce projet de recherche est de modéliser ce type de système de stockage d’énergie avec une nouvelle approche, afin de déterminer quels sont les étapes du processus de stockage qui génèrent le plus de pertes. Ce travail va permettre de guider les ressources de recherche et développement sur les composants les plus impactant, et ainsi accélérer la mise au point de systèmes de stockage hybrides toujours plus performants.

Expanded graphite/thermoplastic composites

This research will develop an easy to implement compounding process to produce thermoplastic composites containing delaminated graphene platelets, starting from a proprietary exfoliated graphite product (MesographTM). MesoGraf is a highly-exfoliated product that contains near defect-free, few-layered and multi-layered graphene. Graphene nanoplatelets have high mechanical and conductive properties and can thus impart high strength, electrical and thermal conductivity when combined with suitable polymer matrices. The main target area for the resulting composites will be value-added products, such as light-weight automotive and aerospace components. The supporting organization is Grafoid, a Canadian company based in Kingston, Ontario. The knowledge generated by this project has the potential to provide new value-added products at a substantially reduced cost to various Canadian industrial sectors, including the advanced materials, automotive, manufacturing and alternative energy sector.

Development of longwave IR colloidal quantum dot solar cell and Development of high throughput characterization methods for solution processed IR colloidal quantum dot solar cells

The potential candidates will help QD solar develop a nano-technology based solar cell using Colloidal Quantum Dots. The research will be focus on the Infrared (IR) portion of the sun’s energy spectrum where standard silicon solar cells are not effective at converting solar energy into electrical energy. More specifically this project will target longwave IR and when combined with QD Solar’s focus on shorter wavelength IR, will create a more complete offering to the marketplace. In addition, a second part of this project will provide a repeatable and automatable way to electrically and optically measure/characterize the IR quantum dots.

Exploring the lived experience of survivors: The link between intimate partner violence (IPV) and traumatic brain injury (TBI)

Past research has established that a high percentage of women in violent relationships experience a traumatic brain injury (TBI), with one article estimating approximately 23 million women in the US living with a TBI from intimate partner violence (IPV) (Ivany & Schminkey, 2016). While previous research has focused on establishing the link between IPV and TBI, further research needs to be conducted into the experiences of these women. The present project seeks to do exactly that, through interviewing of 6-8 women from The Cridge Centre for the Family. From these interviews, the main objective of this project is to better inform frontline workers who work directly with these women, in order to more adequately equip them to serve the diverse needs of the women. As The Cridge Centre for the Family works directly with women who have experienced IPV, this immediately applicable knowledge is the anticipated benefit to the organization.

Sound localization for acoustic monitoring of bird populations in response to fire and oil extraction in Alberta’s oil sands region

Sound localization involves the triangulation of the location of a sound source by recording it on multiple microphones. One potential application of sound localization technology is to monitor the movements of vocalizing animals passively, without the need for a human observer. This project aims to further develop and test sound localization technology, then to apply the technology to monitor the movements and behaviours of birds in Alberta’s oilsands region in the vicinity of inactive well pads in burned and unburned areas. The resulting data will provide insights into the effects of industrial activities and forest fires on the behaviour and habitat use of birds, including several species of conservation concern. The project will also help identify effective well pad remediation techniques, to mitigate future effects on bird populations and accelerate recovery efforts.

Refoulé.e.s de la naturalisation. Analyse des frontières de la communauté nationale (Canada, France, Royaume-Uni)

Depuis le début des années 2000, les conditions d’accès aux droits dans la société d’installation des résidents étrangers ont été reconfigurées dans l’objectif affiché de s’assurer de leur « bonne » intégration comme préalable indispensable à l’acquisition du statut de citoyen. Dans le but de comprendre ce que ces reconfigurations font aux frontières de la communauté nationale (comment elles justifient leur franchissement), le projet présenté ici propose de
s’intéresser aux situations dans lesquelles des États dont les héritages diffèrent en matière de politiques d’immigration et d’intégration (le Canada, la France, le Royaume-Uni), refusent la nationalité ou décident de la retirer. Cette perspective de recherche implique de s’intéresser aux usages que font les bureaucraties de l’immigration des conditions d’acquisition et de retrait de nationalité, et s’appuie sur une enquête de terrain procédant par entretiens et observations auprès des acteurs administratifs et judiciaires (avocats, magistrats) dans les trois cas d’étude.

The Praxis of Agroecology: Sharing Knowledge and Engaging Policy

This research represents the evolution of an existing partnership between USC Canada and Food: Globally Embedded, Locally Engaged (FLEdGE), a SSHRC Partnership Grant project conducting community-based research on sustainable
food systems. The intern will work with these partners to explore the theory and action of agroecology and food sovereignty at the global level and the implications this may have for the future of food systems in Canada. Through primary and secondary research, this project aims to explore the successes and limitations of agroecology in order to expand this work in Canada. The outcomes will benefit USC Canada by increasing their research capacity, assisting in data analysis and knowledge dissemination while also building connections to researcher and policy-maker partners through FLEdGE. Agroecology has the potential to transform Canada’s food system to be more healthy, equitable, and sustainable,
qualities which are increasingly important for the longevity and success of Canadian agriculture.

Mix-and-Match Pipeline to Ease the Creation of New Facial Models for Video Game Applications

Ubisoft has an extensive database of character’s heads represented as polygonal meshes. Those come from two primary sources: processed 3D scans and models made by artists. It would be convenient to use this database to mix-and-match parts of characters to create new human-like character heads. Let’s say we wish to replace the nose of one character with another nose. We want the junction between the nose and the surrounding areas to be as seamless as possible while accommodating for the new nose, which could have a different size. We will rely on geometric methods such as Laplacian surface editing [Sorkine 2004] to extract vertex positions that fit the new nose in the other facial mesh. The vertex positions will result from an energy minimization to reduce surface curvature discontinuities at the junction while maintaining the surface curvature of both the original face and the new nose. Furthermore, a global optimization will allow the deformation of the new nose so that it fits in the related region of the target head, thus resulting in a realistic head.

Removal of THMs by Aeration in a Conventional Lime/Soda Softening Plant With High DOC Water

Surface waters, such as lakes and rivers, often have high amounts of natural organic matter formed from decaying plants and animals. Drinking water treatment plants that use these water sources often face with high levels of carcinogenic chlorine disinfection by-products (DBPs) which are result of reaction between natural organic matters and chlorine that is added to water for disinfection. Canadian water quality guidelines set maximum acceptable levels for these harmful DBPs and hence water treatment plants are obliged to come up with appropriate solutions to meet the guidelines. There are different strategies to reduce DBPs including: enhance removal of organic matters, application disinfectants alternative to chlorine, or removal of DBPs after they have been formed. This project aims to study aeration of potable water as a strategy for removal of DBPs specially trihalomethanes (THMs). TO BE CONT’D

Exploring home range and habitat use during the breeding season of the Bicknell’s thrush (Catharus bicknelli) in New Brunswick Clear-cuts

The Bicknell’s thrush (Cathurs bicknelli) is a rare songbird with the most restrictive breeding range in North America. The Bicknell’s thrush spends its summer months breeding in high elevation, stunted growth forests – a habitat that the species specializes in. In New Brunswick, there has been a documented population decline of 11.5% per year since 2001. After having identified specific geographic areas where Bicknell’s thrush present, this project proposes using radio-tracking to describe individual’s breeding home ranges and extrapolate population size and densities. Contributing to the research knowledge of the Bicknell’s thrush, a federal species at risk, supports Bird Studies Canada’s mandate in using sound research to advise conservation authorities and managers.

User-Side Analyses of the Effect of Laser Data Uncertainties onMapping Applications

Manufacturers’ specifications for laser data acquisition have been used since

the inception of the technology over a decade ago [Habib et. al., 2008; Ussyshkin et. al, 2006].

However, unbiased geostatistical analysis would be valuable in determining – in a pre-analysis stage –

whether or not user-demanded specifications for project-specific mapping applications can be met or

exceeded by the manufacturer’s standards. The partnering organization’s knowledge of false

accuracies, if any, can assess the uncertainty of marrying airborne laser data budgets with the total

uncertainty propagation model [Hare, 2001] – used for hydrographic data error budgeting – in CARIS

HIPS as of now. Ultimately, CARIS seeks to integrate these two error sources and provide a total

uncertainty budget model suitable for both terrain and hydrographic objects.

Finally, assessing the accuracy of LiDAR measurements within a controlled test field will determine

whether or not the actual uncertainties lie within predicted tolerances.
