Development of see-through near-eye display using embedded concave micromirror array for augmented reality applications

Near-eye displays (NEDs) are small displays that are positioned closed to the eye, which conveniently places visual information in the line of sight of a user. NEDs need to be compact and lightweight as they are typically worn on the head, taking the form of glasses or goggles. In this research, we design and build a thin and transparent NED. The proposed NED uses a high fill-factor embedded concave micromirror array (ECMMA), and light field principles for virtual image formation.

Arsenic release from arsenic-bearing minerals

When waste rocks generated by mining activities are exposed to the air and water, various toxic elements may be released to receiving waters and soils. Arsenic (As) is known as one of the most toxic pollutants which can cause damage to the environment and human health. To implement effective source control, it is essential to identify key factors that control the leaching process. The main objective of this research is to determine the rate-controlling steps in the release of toxic elements, with the initial focus on arsenic release.

Determining an effective management strategy for invasive exotic cattails (Typha spp.) in the Fraser River Estuary

Invasive species represent a major threat to global biodiversity, and are projected to increase in impact as globalization promotes the continued introduction of novel species. Proactive research that investigates the ecological, social, and economic threat of novel species prior to or early in their establishment is therefore critical to effective conservation planning. For our research we will be investigating the threat of cattails (Typha spp.) in the Fraser River Estuary (FRE).

Sulphur dioxide sensor for wine quality control

BarrelWise is focusing on the barrel wine aging process which is labor intensive and is logistically challenging for large wineries with thousands of barrels. Due to wine evaporation through the permeable oak barrels, the aging wine needs to be topped to displace ullage and sulphated to protect the wine from oxidation and microbial spoilage. In addition, sulphur levels in the barrels have to be tracked to ensure sufficient protection to the wine, and guarantee that legislated sulphur levels are not surpassed.

Investigation of Novel HPGR and Size Classification Comminution Circuit

Crushing and grinding rock is the largest consumer of energy at a mining operation. Ball Mill grinding is the main technology that is used for fine grinding, yet it is known to be very inefficient with respect to energy consumptions; estimates are that less than 2% of energy input to ball mills translate into particle breakage. The High-Pressure Grinding Roll (HPGR) is known to be much more energy efficient for breaking coarse particles and the present proposal is aimed at demonstrating that the HPGR is more energy efficient than ball mill grinding of fine particles.

Assessing the Efficacy of Empathetic Computing

As the digital landscape continues to evolve, it becomes increasingly more important to understand how technology affects cognition, emotion, and behaviour. This rapid growth of technology has also led to the development of empathetic computing programs with the goal of augmenting people’s lives. It is crucial to discover the practical implications of these systems. This project will focus on analyzing Maslo’s (and the industry’s) empathetic computing technologies through the lenses of cognitive psychology, neuroscience, and evolutionary psychology.

Analysis and Prototype Development of a Drive System and Novel Control Algorithm for Direct Drive Brushless Permanent Magnet Synchronous Motors

Brushless permanent magnet synchronous motors (PMSMs) are widely used in many applications including automations, instrumentation, propulsion, vehicular systems, etc. This project is focused on research and development of a modified drive system and novel control algorithms for PMSMs that could improve efficiency and torque performance compared to conventional methods.

Investigation of Innovative Methods, Tools and Processes on BC Housing’s First IPD Project

In this unique research project, the researchers will document and analyze the collaborative processes and technologies in a housing project, which follows a formal Integrated Project Delivery (IPD) approach. IPD is an emerging procurement method in the construction industry that engages all major stakeholders from the beginning of the construction project. However, there is still a great need for understanding better the required organizational settings, innovative processes, and collaborative tools in order to conduct successfully an IPD project.

The effect of cultivation conditions on duckweed nutritional profiles, with applications for aquaculture and aquatic ecology

Water lentils (duckweeds) are small aquatic plants that naturally found in ponds, lakes, and streams. Water lentils have been consumed by human populations for decades, and are a plant-based and sustainable source of proteins, potassium, iron, and fatty acids. Fifty years of ecological studies on the effects of abiotic factors on plant nutrients have shown that slight tweaks in temperature, salinity, and species mixtures can significantly increase plant nutrient levels and growth rates in nature.

Use of Jetti Catalysts in Waste Rock/Tailings Treatment

Bio-heap-leaching is a hydrometallurgical process used to process low grade chalcopyrite ore as the cost of alternative routes of processing and refining are not economically viable. However, a viable solution has been found: to add a catalyst that dramatically enhances the kinetics of leaching while not being too expensive, environmentally detrimental or affecting downstream processes. Jetti resources is using this technology to enhance the heap-leaching rate of chalcopyrite.
This new catalyzed leaching technology can also be applied in tanks and other reactor configurations.
