The composite products possess an essential role in different industries, including aerospace and marine. Automation has been introduced in the manufacturing line of composite products aiming to improve the production rate. However, the downside with the automation application in the manufacturing line is the formation of defects in the final product, while the conventional inspection methods (e.g., human eye inspection) are not practical anymore. This project aims to use computers for fast inspection and optimization of the final product.
In Canada, screw piles are widely used in supporting residential and commercial buildings. While the design of screw piles are general well-known to engineers, the uplift displacement of screw piles during the winter season is still mysterious, especially in cases where screw piles are installed in frost-susceptible soils. The present project is intended to conduct a field test of screw piles in the clay of Alberta and therefore to provide a case study for the engineering performance of screw piles in cold regions.
? Comprehensive review of S2EBPR, with a focus on operation, performance and microbial structure
? Evaluate and understand the effect of operational factors on conventional and S2EBPR systems by water quality monitoring, carbon, phosphorus and nitrogen mass balance, metabolic activity and kinetic tests and microbial ecology analysis
Climate Change (CC) mitigation and reduction requires a strong effort to develop and put into use clean energy options that significantly reduce anthropogenic CO2 emissions. In Canada, the transportation sector accounts for 25% of all emissions. Hydrogen fueled vehicles is one option that has a great potential to reduce Canadian and global CO2 fuel emissions.
This research project evaluates the environmental performance of two tailings management areas at a decommissioned mine site in Ontario. The tailings areas are decommissioned with a water cover and continue to be managed and monitored with ongoing water treatment. The project revisits groundwater modelling that was conducted prior to the decommissioning of the site and updates it using nearly three decades of environmental monitoring data and advancements in software. The groundwater model will determine the rates and directions of groundwater flow from the tailings areas.
Rising material costs, lack of quality control, labour shortages, challenging climates and significant on-site waste continue to be the challenges encountered by the Canadian construction industry. The collaboration between the research team and NEXII will develop the technical know-how for the new generation building panel products to address these challenges. The new NEXII panel is a three-layer composite “sandwich” structure consisting of an expanded polystyrene insulation (EPS) core between two layers of Nexiite, an innovative material produced by NEXII.
Lift stations are an underground utility transporting wastewater from residential or commercial sources to wastewater treatment plants. Lift stations are defined as a post-disaster structure according to national building code of Canada, which are required to remain operational immediately after earthquakes. A wealth of evidence from historical post-earthquake reconnaissance has confirmed the excellent performance of high-density polyethylene (HDPE) pipelines under earthquakes.
An integrated methodology and platform are proposed to improve circular engineering of the built environment to reduce construction waste, carbon emissions, and costs associated with the adaptation of dated existing buildings. Novel design methodologies and technologies are explored for optimizing design option generation using various spatial, environmental and economic factors simultaneously.
Bacterial cultures are sometimes added to groundwater to increase the rate of degradation of contaminants. Three cultures that are able to completely biodegrade their primary compound to non-toxic end products in the absence of oxygen have been enriched from contaminated soils. The goal of this project is to demonstrate the efficacy of these cultures in a controlled field experiment. High resolution temporal and spatial data will be collected to estimate degradation rates, and support a process level understanding.
