Heating and cooling in residential and commercial buildings account for 20% of total energy consumption in Canada. Conditioning indoor air using less energy is closely associated with minimizing production of greenhouse gases and making a sustainable global environment. In this study, we apply a nanocomposite fibrous membrane for an energy recovery ventilator (ERV). Heat and moisture from an exhaust contaminated indoor air are captured via ERV and recycled for conditioning entering outdoor air, ultimately resulting in energy savings and improving the indoor air quality of buildings.
Hydropower dams are significant investments and their integrity affects many stakeholders. Failure of a dam results in catastrophic events which cannot be mitigated. Seismic evaluation and prediction of dynamic response of dams need in depth assessment which has always been challenging with complex dam-water-foundation interaction. Impounded water considerably affects the response of a dam during a seismic event.
Wild blueberries are an important crop to this region as this is the only area that wild blueberries are naturally occurring. The changes in wild blueberry crop conditions caused by improved management practices over the past decade has caused increased plant density and leaf foliage. This extra foliage has made it more difficult for the harvester operator to clean debris (leaf, soil, sticks, etc.) from the blueberries before they are placed in the loading bins.
Micro-chip implantation provides a reliable, cost effective and less painful method of reuniting the lost pets with their owners. However, the formation of tumors and inflammation at the micro-chip implant sites has been observed in companion animals as well as rats and mice. Therefore, there is an emerging need for alternative material to coat or encapsulate the micro-chips to control the inflammatory reaction after the implant and the potential tumor formation.
This project will combine filtration characterization and advanced 3D imaging and modelling of material structures to find ways to improve the recovery of process water from difficult-to-treat tailings that are the by-product of mining and mineral processing. This process is called solid-liquid separation and it is a critical area for the reduction of oil sands tailings volumes. Due to the chemistry and solids composition of oil sands tailings, they are extremely resistant to dewatering.
Using modern machine learning techniques and analytical tools, the intern will create a joint recommendation and inventory management system that will be able to automatically choose the ideal package for Chic Maries customers. This package will include curated clothes for each customer based on their tastes, buying history and any other data they wish to provide. These selections will then influence what merchandise Chic Marie will purchase from suppliers, ensuring an optimal level of inventory and efficiency from supplier all the way to the end user.
With increased emphasis on water quality in the Lake Winnipeg watershed, more stringent guidelines for wastewater effluents are being implemented. Smaller municipalities and remote communities, with limited financial resources, will be facing regulatory pressures, particularly around discharge of phosphorus, as well as micropollutants such as estrogens, pharmaceuticals and pesticides. To ensure the release of high quality wastewater effluents post-lagoon treatment technologies such as subsurface filtration systems are being employed for enhanced removal of pollutants.
Klashwerks is an Ottawa-based engineering design and Technology Company founded in 2016 that focuses on the emerging connected car market. They are currently developing an intelligent driver companion for smart car. One desirable feature of this product is to offer the possibility to drivers to interact with the device by simply using their hands. Gestures constitute indeed one of the most powerful modality for humans to interact with computers.
Since energy is the major concern in current and future mining operations, energy efficient technologies are a major focus for research and development. The CAHM machine was developed based on principals of energy efficient particle breakage by compression. The machine design was based on computer simulation and modeling results indicate the potential to reduce comminution energy requirements by 50% as compared to present technologies. CAHM simulations show that the technology can achieve high reduction ratios, consuming less specific power, which translates into energy efficient operation.
Cu and Ni minerals that have great economic value mostly exist in the form of sulfides, making them difficult to extract using hydrometallurgical processes. Currently, heap leaching is the most economical way to extract these metals from low grade ores. Copper recoveries of many chalcocite heap leaches report around 70% copper recovery. However, the chalcocite leaching reaction has several stages. The first stage leach is characterized by 50% copper extraction and the conversion of chalcocite into a second stage of covellite (CuS) which is very difficult to leach at ambient temperature.
