Mine waste rock drainage is one of the most challenging and lasting global environmental issues facing the entire mining industry, regulatory agencies and society as a whole. Mine drainage can be alkaline, neutral, moderately or extremely acidic and contains significant levels of sulfate, dissolved iron, and frequently a variety of heavy metals and metalloids. As […]

Cohesys is developing a surgical tape indicated for stabilizing fractures to the face and cranium. In order for a tape to function inside the body, the adhesive must be non-toxic and be able to adhere and maintain strength overtime, in an environment which is wet, filled with proteins and other molecules and be able to […]

This project aims at solving the difficult problems faced by indoor positioning and related issues, which are part of the future development direction. For different positioning environments and positioning requests, the project will explore the corresponding positioning schemes, conversion mechanism sand switching strategies. The project will use the geomagnetic-based technology that does not require additional […]

The evolution of aerospace technologies and automated systems has been accompanied by the phenomenon of “de-crewing”. A large body of current research focuses on how to move to single-pilot operations (SPO), but a major barrier to the implementation of SPO and other autonomous commercial aircraft operations is that advances in human-machine interactions and human factors […]

Paints are complex colloidal suspensions that usually contain binders (resins), solvents, pigments and rheological modifiers. From production to applications, these raw materials should remain uniformly mixed and stable during pumping processes and storage, as well as after application with brushes, rollers, spray guns, etc. It is very important to know how the paint behaves under […]

This project aims to develop a pneumatic (compressed air) powertrain to be used in a 40-feet bus for municipal transit and school buses. Since the transportation sector is one of the prior contributors of Canada’s GHG emissions ( 24%), any alternative solutions to conventional vehicles carries significant importance to reach the GHG target that Canada […]

In an effort to ensure pipelines continue to operate in a safe condition, various inspections and assessments are completed on a continual basis during their operating lifespan. These assessments include radiographic or ultrasonic examinations, forms of non-destructive examination (NDE), of circumferential girth welds formed between multiple pipe sections. The purpose of this project is to […]

The objective is to: (1) develop full-coverage path plans for an autonomous DOT vehicle, designed and developed by Dot Technologies Corp., operating in a farm field, and (2) avoid collision with other agricultural machines operating in the same field, e.g., a combine, via model-based motion tracking using on board camera vision. A software suite, with […]

Wollastonite(CaSiO3) and diopside(CaMgSi2O6) are silicate minerals occurring in the mining operation near Kingston. Quantity of each mineral in the deposit vary from 30 to 40%. An efficient separation of wollastonite from diopside represents a challenge in processing this ore. Efficiency of flotation separation at high levels diopside is not consistent since both silicates respond the […]

The intent of this research is to study fire dynamics and the threats it imposes on people, property, business continuity and environments, namely at wildfire-urban interfaces (WUI). Worcester Polytechnic Institute of Boston, MA, is equipped with modern technologies, not yet available at my home institution, that can be used to build a comprehensive analysis of […]

The main concern for helmet performance is the reduction of skull and brain injury risk during impact events. Combinations of shell materials, foams, and three-dimensional engineered structures are used to design hockey helmets. Using current helmet evaluation techniques, the contributions of each of these components cannot be directly assessed. In the proposed work, high-speed X-ray […]
