The effect of indoor light spectrum and intensity on viability and infectivity of indoor pathogens on different surface materials

Indoor environments have became a predominant habitat for modern individuals. Physical spaces can have meaningful effects on how we feel, how we interact with others, and how we perceive our experiences. Comfort in physical spaces encompasses different facets including thermal comfort, visual comfort, noise nuisance, as well as indoor air quality. Combination of these make a built environment a healthy environment for its occupant.

Development of environment-friendly seismic-resilient precast beam-column modules

The inordinate carbon footprint of the precast concrete industry mainly originates from its raw material supply, predominantly cement. Besides, deficient design and detailing of the joints in precast structures result in their inherent poor seismic performance. Thus, it is crucial to investigate greener alternatives to raw materials along with innovative structural design in precast concrete structures to obtain a wholesome sustainable solution for the precast concrete industry.

The Transitioning Youth with Disabilities and Employment Project – “The TYDE Project” – Focus on Gender Equity: Why are jobs distributed so unequally across gender?

Employment is important for ensuring social inclusion of people with intellectual and developmental disabilities, who commonly use the identity term self-advocates in Canada. Self-advocates are much less likely to be employed, and work fewer hours a week and often earn only minimum wage. When gender is taken into account, men are hired more frequently, work longer hours, and earn higher wages. A better understanding of employment barriers facing women and gender diverse self-advocates is needed to protect and promote the right to work.

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.
In this project, we study and explore state-of-the-art adversarial patch attacks and their defences.

Clarifying the biochemical basis of smoke-taint in grapes and wines

When grapevines are exposed to forest fire smoke they often trap the compounds responsible for the odour of smoke within the ripening berries. Through poorly understood processes, grapes may transform these compounds into forms that are not readily detected by smell or current testing procedures. The yeasts used for fermentation may break down these storage forms, regenerating the smoky aroma and tainting the resulting wines.

Evaluating the Environmental, Social and Governance (ESG) Risk Assessment Method in Supporting Decisions for Loan Approval by Financial Institutions

Financial institutions ensure borrowers’ ability to repay the loan before lending them for the pursuing projects. The ESSAFIN Logic 1.0 software tool is available for evaluating loan proposals based on the Environment, Social, and Governance (ESG) criteria. The tool has a potential for improvement to account for the lack of critical practical application and evidence-based literature support.

Analog ASIC Artificial Intelligence at the Edge

Enabling Analog Artificial Intelligence by the systematic generation of Analog Neural Networks from well-known Artificial Intelligence software tools. The circuits and methodologies developed here enable “AI at the Edge” meaning local, low power, analog AI that provides, for example, medical devices that analyse signals to asses the need for intervention; voice recognition devices that do not send recordings to the internet; smoke detectors that recognise the chemical composition of gas in the air and similar.

Researcher shifts work, finds “silver bullet” for COVID-19 protection

The COVID-19 pandemic sparked an urgent need for innovation in all aspects of our lives – and researchers rose to the challenge. From COVID-19 diagnostics and treatments to changes in how we work and receive healthcare, the pandemic has fast-tracked innovation across sectors. 

High-potential researchers and businesses around the world did a pandemic pivot, shifting their work and resources to respond to the world’s pressing need for solutions. In Canada, Seyyedarash (Arash) Haddadi’s story is a standout example of innovation partnerships helping to counter the COVID-19 threat. 

Li4Ti5O12/Hard Carbon Anode for Fast-Charging Batteries for Grid Applications

Fast-charging Li-ion batteries have great potential for electricity storage from renewables, frequency regulation, and peak shaving in large-scale grid applications. The Li-ion batteries must have a fast response, high rate performance, high power capability, and low cost to meet this increasing demand for grid applications. This project between Dr. Jian Liu’s group at the University of British Columbia (UBC) and Tycor UPS will develop a hybrid Li4Ti5O12/hard carbon anode to enable Li-ion batteries fast-charging capability and low cost.

Wireless Readout Integrated Microwave Sensor for Detecting Ice/Snow in Harsh Environments

Several de-icing systems have been developed to reduce economic losses and safety hazards due to ice and snow accretion on home pathways. These de-icing systems need to be energy-efficient, and therefore, must be accompanied by high-performance sensors capable of accurately detecting ice and snow to control the de-icing system. In addition to this application, recent industrial developments have shifted the paradigm of ice sensors towards extreme environment applications requiring sensors be operated in harsh conditions.
