Heating and cooling in residential and commercial buildings account for 20% of total energy consumption in Canada. Conditioning indoor air using less energy is closely associated with minimizing production of greenhouse gases and making a sustainable global environment. In this study, we apply a nanocomposite fibrous membrane for an energy recovery ventilator (ERV). Heat and moisture from an exhaust contaminated indoor air are captured via ERV and recycled for conditioning entering outdoor air, ultimately resulting in energy savings and improving the indoor air quality of buildings.
Pesticide detection in water has become a high priority worldwide, from protecting the population from environmental contamination due to agricultural pesticides, and bio-threats from terrorist activities. An exhaustive characterization of water pollutants requires laboratory-based analyses which are inherently slow and expensive. Thus, regarding the above mentioned pesticide contaminations, developing a real-time and in-situ detection technique would be very valuable to rapidly protect the population and the environment, especially in remote places.
The ultimate goal of this project is to detect and localize leaks in pipelines in real time. Hifi Engineering has developed
distributed fiber optic sensors. Measurements are obtained at evenly spaced intervals along the pipeline (called
channels). This project aims to develop data processing tools to improve leak detection and localization. Many events
occur along a pipeline whose effects are registered by sensors (trucks driving by, compressors turning on, leaks).
Events are registered in many channels as sounds propagate down the pipeline.
CO2 is a greenhouse gas that impacts climate change. The Carbon Upcycling Technologies has developed a technique to attach gaseous CO2 molecules to graphite. In this project, this graphite will be converted to graphene using chemical oxidation methods. The one-atom thin monolayer graphene oxide will have potential applications in variety of industries, such as waste water treatment, gas separation and reinforcement of plastics.
Corporate improv training is becoming a popular and effective method for enhancing a host of workplace skills such as leadership, communication, problem solving, collaboration, and adaptation. However, there is a lack of empirical research looking at the cognitive impacts of improv training in the workplace. As such, I am proposing to conduct a twelve-week improv training program with a targeted group of Vancity employees, with two specific objectives in mind.
The efficiencies of biomass-fueled power plants are much lower than those of natural gas and coal-fueled plants because exit steam temperatures are restricted to inhibit corrosion of superheater tubes. Nexterra needs to raise steam conditions from 403?C to 460?C in future systems in order to satisfy customer demands. The raise in the probability of corrosion issues due to contaminants in the fuel. In order to achieve the more aggressive steam conditions it is necessary to modify boiler design to include selection of the boiler tube materials that are resistant to corrosion.
The Independent Electricity System Operator (IESO) coordinates electricity generation and transmission to ensure a reliable and stable electricity supply for the province of Ontario. Human operators monitor the power grid with the help of automated energy management systems. Increasing amounts of data, electricity demand, and renewable generation mean these operators need new tools to help them monitor and manage grid reliability. These tools include displays that consolidate data, support operator decision-making, and reduce the likelihood of human error.
Alternative fuels and energy resources play a key role in both the short and long term sustainable development of transportation. Ammonia (NH3) is the only carbon-free chemical energy carrier (other than hydrogen) suitable for use as a transportation fuel. NH3 can be produced using either fossil fuels, or any renewable energy source, using heat and/or electricity. Comparative analysis related to ammonia production and ammonia based applications such as transportation options will be undertaken.
In order to enhance the capabilities of fuel cell test stations, a new tool for fuel cell diagnostics based on nonlinear frequency response analysis (NFRA) will be developed. NFRA applies a perturbation of the operating current and measures the voltage response of the cell. By varying the frequency of the perturbation, processes with different dynamics (i.e. fast or slow processes) are excited and can be probed individually. From this frequency response, the state of the cell can be determined.
A rice husk pyrolysis reactor producing syngas and char was developed by GreenGenTech Energy Inc. (Ottawa, ON) and is currently being built and commercialized in China by a partner company called Ruizhantai. The reactor is fully functional and some sites have been running continuously for two years, although requiring skillful operation during start-up or when agglomeration of husk occurs. Aiming at optimized and more automatically controlled operations, GreenGenTech Energy Inc.
