Integrated multi-trophic aquaculture (IMTA) is a technique by which the environmental impacts are minimized while efficiency is increased. However, these aquaculture activities can put a strain on their surrounding environment, as operations encroach on valuable wetland areas, act as a stressor on local water resources, and effluent waste can increase the concentrations of pollutants in nearby waterbodies. Hence, development IMTA system that can produce fish and marketable co-products without drastic water demands will improve operations.
Due to the length and intrinsic flexibility of cable-supported bridges, wind causes serious challenges to designers of such structures. To ensure the safety of these bridges, it is common practice to test scale models of bridges in the wind tunnel. As bridges are getting longer, simplifications used for typical wind tunnel test become questionable. Therefore, this project aims at developing a new type of wind tunnel tests for bridges in order to check whether these simplifications are safe for very long bridges.
The joint research's primary goal is to pursue the most optimized design and materials of new interlocking barriers to prevent coastal erosion and reduce flooding, which are growing concerns of coastal communities like Newfoundland and Labrador. The research results will support investors and industry to have access to a cost-effective and efficient barrier to protect their natural resources and cultural heritage in a sustainable way.
The waste generated from construction, renovation and demolition (CRD) activities accounts for around 27% of all waste generated in Canada. The large amount of CRD waste which could be prevented or recycled is sent to landfill without utilization, resulting in environmental problems and waste of resources. The aim of project is to provide the best management practices and policy recommendations for CRD waste management in Montreal West.
Pipelines are extremely important for the transportation of oil and gas. Buried pipelines can move in a relatively large distance under special scenarios, e.g. slope failure. Meanwhile, the surrounding soils are subjected to a large deformation. This project aims to develop a computer modeling technique to analyze the large-deformation behavior of soil and its impact on the pipeline. The result will be compared with a previous physical test so that the reliability of this new technique can be evaluated.
An Indigenous community living near Alberta’s oil-sand mines is concerned that mining operations may be harming the rivers and lakes where they fish, hunt and trap. The research looks at finding the locations along the edges of rivers and lakes where there is evidence that mining operations may be affecting these waterbodies. The unique part of the research is that Indigenous knowledge, which is the wisdom owned by the community, and Western science are being combined in complementary and respectful ways to find the affected locations along the edges of rivers and lakes.
An early-stage design analysis methodology will be investigated for evaluating preliminary building envelope design alternatives using advanced computation and analysis tools. Design alternatives will be generated based on different envelope materials, structure, insulation types and window-to-wall ratios and evaluated based on selected metrics including energy use, daylighting, life cycle analysis and life cycle costing. A master-planning project in Mississauga, Ontario, will be used as a test-bed for the methodologies explored in this research.
This project aims to develop an itinerary demand forecasting model that can handle long-term and short-term forecasting and adjust its parameters under changing situations. General long-term prediction models are relatively precise because the context often remains stationary over time, but can not quickly adapt to unforeseen events, like the global pandemics. It is necessary to develop an adaptive model with multi-horizon perspectives. The model will integrate external data sources to output a plausible range of future booking status.
The project seeks to discover the optimum design and commercialization strategy for newly developed sandwich structures derived from recycled plastic for the civil engineering sector. The sandwich structures are highly sustainable and could potentially consume large amounts of the rapidly produced plastic waste. The final sandwich product would have the potential to be used in various applications such as roof panels and exterior/interior walls of buildings.
Ultraviolet-C (UV) light is able to damage cells and organic matter to make water, air, and high touch surfaces safe for the public. UV-C lamps render microorganisms harmless by damaging their cell structure and DNA. UV-C based water treatment has safely been used for decades by water utilities around the world. Recent developments in technology and research have allowed for an even wide application to clean surfaces, air, and water using UV light.
