Certified Defense Framework against Patch Attacks on Images

Adversarial perturbation of all the image pixels is computationally intensive and may not be realized in practice. In contrast, an adversarial patch attack where an adversary can choose to perturb a specific subset of pixels in an image, is more practical in fooling a trained image classifier or hiding a person from an object-detection model.

Efficacy of Harm Reduction Approaches to Hoarding in Social Housing

Hoarding involves keeping so many objects that the home becomes unsafe or unhealthy. Due to fire risks and other issues, hoarding can also be unsafe for neighbours – risks that housing providers must manage. A common strategy in social housing settings is to evict the tenant or forcibly clean out the unit, traumatic practices that […]

Investigating social-ecological enabling conditions for the revitalization of Indigenous clam management systems in an urban context

The general objective of the proposed activity is to increase the future productivity of Burrard Inlet and the contribution of seafood to the diet of Tsleil-Waututh Nation (TWN) members in support of the TWN Cumulative Effects Monitoring Initiative. Specifically, we propose to identify the primary environmental drivers of clam productivity and species composition in Burrard […]

Assessing potential interactions between wild and hatchery Chinook salmon in the early marine environment

Estuaries are crucial stopover areas for juvenile salmon during outmigration and especially for Chinook salmon who can reside in this habitat for over a month. Many populations of Chinook salmon from the Pacific Northwest are threatened and endangered making conservation important for this species. In response to relatively small returns to spawning grounds, hatchery production […]

Toxic Disinformation: Credibility Attacks Against Journalists

Journalists around the world face attacks on their reputations and efforts to undermine the impact of their work. These “credibility attacks” can take the form of false allegations, insults about their character or professionalism, or denigration of their social identity. They often take place online, and in some cases involve disinformation tactics such as doctored […]

Real-time Energy Analytics for Distributed Facilities

New meters, sensors and other field data collection devices are providing a plethora of real time system operational data for building, industrial plants and production systems. At the same time, building owners, industrial plant owners and campus based operations are being challenged with managing their energy use both through conservation and demand management processes. In […]

The carbon abatement potential of pine beetle affected wood biochar in British Columbia

This project aims at providing a comprehensive appreciation of the net carbon capture potential of using pine beetle affected wood as feedstock for biochar (a carbon rich material) production and use throughout British Columbia. The carbon capture potential will be assessed by balancing the greenhouse gas emissions associated with the production, transport, and amendment of […]
