Application of Variable Speed Drives for Improved Grinding Energy Efficiency

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.

Optimization and validation of carbon nanofiber catalyst supports in fuel cell stack

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.

Comparative Analysis of Milking Systems in Nova Scotia to improve efficiency and sustainability of water resource

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.

Kinetics of dispersion of fine phosphate particles associated with organic matter

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.

Development of improved condensing system for biomass pyrolysis process

ABRI-Tech and Memorial University (MUN) have been collaborating to optimize ABRI-Tech’s pyrolysis system to convert woody biomass (i.e. demolition wood waste, sawmill residues, forest residues, agricultural and other residues) to bioproducts.

Graphene Oxide membranes for acoustic drivers

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.

Resource Allocation for Cloud-Based Notary Service

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.

A remote sensing-based wetland inventory and classification framework for Newfoundland and Labrador using satellite optical and synthetic aperture radar data

This project aims to develop a remote sensing based framework for Newfoundland and Labrador (NL) wetland inventory and classification and monitoring through the synergistic use of satellite and airborne multi-spectral and ortho-imagery and space-born synthetic aperture radar (SAR) data. The proposed project involves collaboration from C-CORE, Ducks Unlimited Canada, and Santec. The results and approach will help Ducks Unlimited Canada for conserving wetland and for waterfowl, wildlife and people.

Evaluation of cyanide and thiosulphate lixiviant systems for KSM Seabridge gold circuit

Most of the gold that is produced by hydrometallurgical processes is recovered by cyanide leaching. However, the reactive nature of some minerals questions the applicability of cyanide technology for selected applications. The current research is designed to evaluate the cyanide technology as well as an alternative processing path for a particular material through extensive experimental program. The project will yield the mathematical models describing all chemical processes in each circuit, as well as mass and energy balances based on laboratory data and scientific reasoning.

Performance Based Seismic Design Guidelines for Sprayed-FRP Retrofitted Circular Reinforced Concrete Bridge Columns

The proposed study will develop seismic design guidelines for retrofitting deficient concrete bridge columns with sprayed fiber reinforced plastic (FRP). Seismically deficient bridge columns (with different aspect ratios and transverse reinforcement ratios) retrofitted with composites will be tested under reverse cyclic loading. The tests will determine various damage states in terms of strain and drift.
