Powder metallurgy uses metal powders to produce parts of varying complexity. The processes can generally be divided in two big steps. The first is to form the powder into the required shape. This is generally done by pressing or molding the powder. The second step is to consolidate the powder into a solid piece of metal. This is done by heating the formed powder just below its melting temperature. At this point the metal particles will slowly coalesce into a uniform metal structure.
Unconventional gas reservoirs are a great energy resource in the province of BC and Alberta and thus for Canada in general. Extracting this resource is not as straight forward as conventional gas reservoirs and requires hydraulic fracturing, also known as fracing or fracking, which has recently become a controversial topic in the public eye. This research project will examine water and fluids used in and returning from frac operations with respect to its geochemistry and bacterial populations.
Traditional fleet management systems suffer from zone-based aggregation. i.e. they use aggregate zone-level road and terrain characteristics to estimate trip performance indicators. In addition, most of these systems require intermediate ad-hoc staging tables to generate trip performance reports. To address these limitations, this research aims at developing a segment-based fleet management system for near real-time analysis. The proposed approach uses static segmentation to associate road and terrain characteristics with each segment of the road network.
The research program is aimed at developing operating systems that enable grinding mill speeds to be controlled in responses to variations in ore properties. Although there are studies that show speed control can improve productivity and significantly reduce energy requirements, mines presently used fixed speed systems for their ball and tower mills. With development of new variable speed drive systems that can retrofitted to the fixed speed systems, there is an opportunity for mines to introduce the technology for their operation.
Motivated by the urgent need for clean and sustainable source of energy we propose to develop structurally and chemically controllable fuel cell catalyst layers based on ultrafine nanocomposite carbon fibre catalyst support. Manufacturing parameters will be controlled and optimized to investigate the effect of microstructure on key performance factors. Ultimately, the knowledge gained from this study will pave the way to building more efficient fuel cells. Current phase of the project involves validating our design by in-situ testing.
This project will provide a detailed evaluation of the energy, water and labour requirements of the four different types of milking systems used in Nova Scotia. Nova Scotia currently has 36 robotic milking systems installed with more expected in the near future. It is generally considered that robotic systems use more water than free stall systems, however tie stall systems use less than free stall. If the industry is moving to high water use systems then such evaluations are important to ensure a sustainable and responsible approach to water use if achieved.
This research project seeks to improve the process which is used to recover fine phosphorous particles from mine tailings. Phosphorus based fertilizers are important for plant growth and essential to large-scale, high-efficiency farming methods. However, the processing method used to obtain phosphate from phosphate-bearing ore is not very efficient. Upward of 13 % of the available phosphate is lost to the waste stream during processing, which represents a major inefficiency and creates a large environmental problem.
ABRI-Tech and Memorial University (MUN) have been collaborating to optimize ABRI-Techs pyrolysis system to convert woody biomass (i.e. demolition wood waste, sawmill residues, forest residues, agricultural and other residues) to bioproducts.
The Graphene Audio group at TandemLaunch is working to revolutionize loudspeaker design through the use of graphene composite materials (Graphene-CMs) in loudspeaker membranes. Graphene is a newly discovered material with exceptional mechanical and electrical characteristics. Its low mass and high strength make it ideal for use in acoustic transducers offering an immediate benefit over existing loudspeaker technologies.
This project seeks to improve the manufacturing techniques and acoustic characteristics of these Graphene-CMs.
Cloud computing has emerged as an important platform for business and companies, providing a cost-effective way to scale business service with users demand. The proposed research project aims to take full advantage of cloud computing for legal-service companies in Canada, with a particular focus on cloud resource allocation. Unlike conventional resource-allocation schemes that are either centralized or distributed, the proposed research will develop a new hybrid resource-allocation scheme that enjoys clear advantages over conventional schemes.
