This research project to enhance evacuation planning and resilience hub design in Edmonton will be completed through a partnership between the University of Alberta, Alberta Ecotrust Foundation, the City of Edmonton, and Mitacs. The graduate student interns will complete and guide research tasks related to data collection (e.g., survey and focus groups), data analysis, and research dissemination.
A large portion of the infrastructures, including bridges in Manitoba, are constructed on problematic alluvial soils such as soft clays. One of the concerns related to the piled foundation bridges is downdrag which is a downward movement of the soil relative to the pile. Drag force is an additional axial force imposed on the pile due to downdrag. Underestimating this force may have detrimental impacts, including excessive settlement or even failure of structures.
Modern power systems wherein renewable resources such as solar and wind power are extensively used need to rely on some means for energy storage to address the intermittency of such resources. This proposal investigates a class of power electronic converters that are able to connect battery energy systems to the grid and provide multi-directional pathways for the flow of energy. Various models will be developed for these converters to facilitate their design, analysis, and computer simulations.
Canada is one of the largest per capita users of fresh water in the world. A blind spot in water consumption is that people are often unaware of how much water is being used. One solution is to provide instant feedback on water consumption to users and use behavioural interventions to promote water conservation among users. In this project, we will conduct a literature review on behavioural interventions that promote water conservation.
Carbon capture and sequestration (CCS) is a practical solution for reducing the overall green house gas (GHG) emission and environmental footprint of the civilization. The CoFlow simulation software developed by CMG is one of the only tools available for predicting the performance of the CCS applications. Generally, there are technical challenges and prediction deficiencies associated with processes involving injection of high-pressure CO2.
Additive Manufacturing is a rapidly growing technology in the gas turbine industry. Its numerous advantages allow for the design of complex shapes which have not been possible in the past, using conventional manufacturing method. The parts could be manufactured on demand, with reduce cost and lead time. Selective Laser Melting is the common method to additive manufacture metal super alloy parts for combustors and turbines. The anisotropic microstructure from the printing process pose a challenge to numerical simulation and conventional predictive models.
The increasing concentration of CO2 has caused various adverse environmental effects on the Earth’s oceans, land, and atmosphere, leading to a worldwide consensus on the necessity of action and commitment to emission reduction. Carbon Capture and Storage (CCS), which involves capturing CO2 resulting from industrial processes for storage in underground geological formations, has proven to be an effective method for CO2 emission mitigation. CO2 absorption using chemical solvents such as amines is a prevailing but technically challenging and rather low-efficiency method of carbon capture.
The objective of this collaborative research project, between American Bureau of Shipping and Memorial University, is to improve the safety of ships in Polar waters. ABS is continuously updating information to its clients on practices for the safe operation of ships. The goal of this research is to provide technology and operational guidelines so that ships can operate safely in regions where ice is present. This requires protecting the ship, its passengers and crew and the marine environment.
Pressurized metered-dose inhalers (pMDIs) are widely used to deliver drugs to the lungs for treatment of respiratory diseases. However, targeting delivery of inhaled drugs to the lungs is not straightforward. The airways of the mouth and throat present a barrier through which inhaled particles must penetrate in order to reach their target sites in the lungs.
Presently the electrical grids of Manitoba, Saskatchewan and Alberta are operated with limited energy exchange between them. Connecting the three provinces together with a “Western Canada Grid (WCG)” could yield significant advantages. Connection with HVDC transmission is attractive due to its control flexibility and stability. This project will investigate optimum converter types and control methods for implementing a successful Western Canada Grid.
