In the backcountry, avalanche risk is managed by first assessing avalanche hazard and subsequently carefully choosing terrain and travel procedures accordingly to mitigate the identified hazard. What are suitable terrain choices under different types of avalanche conditions and how are choices made? With this project, we quantitatively examine large-scale terrain choices in two commercial backcountry skiing operations in British Columbia. Our data set covers four resp. sixteen winter seasons with documented operational decisions on where to ski.
The Nsyilxcn (Syilx Okanagan Interior Salish) language is critically endangered; fewer than fifty Elder speakers remain, no young people are learning at home and no effective school programs. Syilx people are highly invested in creating language opportunities, including teaching positions in schools, daycares, and adult programs, however no young speakers exist to staff them. Questions arise: how can we make Nsyilxcn language transmission more effective? What are the barriers to success, including linguistic, methodological, organizational, and community capacity challenges?
Have you ever wondered what is underground below your feet? In this project, the intern will work at CRM Geotomography Technologies on developing a compact detector that will make it possible to construct 3D images of underground structures. The concept is similar to an X-ray, except that naturally occurring particles called atmospheric muons are used instead of electromagnetic waves. This technique is useful whenever it is necessary to scan volumes of underground earth.
The successful commercialization of new cathode materials for lithium ion batteries requires an improved and detailed understanding of the correlations between their structure, properties, and performance. Such a correlation will provide a foundation for better understanding the degradation mechanisms and optimized operating conditions for these cathode materials; pairing new battery materials with ideal applications and standardizing the methods by which these materials are evaluated.
Since the beginning of recorded time, humans have been developing ways to make themselves more beautiful or otherwise change their appearance. The hair-care industry itself has a huge global economic power: its estimated total value is $47B annually. However, beauty does not come without a price: methods currently being used for hair colouring and styling damage hair greatly. More importantly, they involve treatments that have negative effects on human and environmental health.
In 1995, proportions of several stocks of Fraser River sockeye salmon (Oncorhynchus nerka) began to enter the Fraser River system early to spawn creating uncertainty in mortality and spawning abundance estimates. This has created large problems for fisheries management in their attempt to protect less abundant stocks. To address this issue, Fisheries and Oceans Canada performed a large tagging study of sockeye salmon using radio telemetry in the Harrison River.
There is a strong push toward producing fuel cells on a commercial scale. This means a greater focus on production speed and yields with a need to understand the unintended features that arise from larger-scale manufacturing processes. This project requires the set up of state-of-the-art, camera-vision, defect detection equipment to find and collect observed membrane features. These features will then be catalogued and tested to determine their impact on membrane durability and whether they affect later processing steps.
Hydrogen powered polymer electrolyte membrane fuel cells (PEMFCs) are a clean energy technology that generates electricity without harmful emissions at the point of use. Current R&D efforts mainly target to commercialize PEMFCs through cost reduction and durability enhancement. The lifetime of PEMFC is limited by the degradation and failure of the polymer electrolyte membrane (PEM). The proposed research project addresses the mechanical degradation mechanism, a key factor reducing the lifetime of PEMs, by developing in-house ex-situ mechanical durability evaluation tools.
During the proposed internships, adaptive corrosion protection system (ACPS) will be developed as a stand-alone unit to provide optimum corrosion protection by changing the protection power according to the changes in environment or the material properties. This will allow the dynamic adjustments by implementing the feedback loop for the protected system. The proposed ACPS will also use efficiently stored energy from harvesting or charging. The proposed ACPS will significantly reduce and/or eliminate human interaction for an efficient and a cost-effective.
