Linear Induction Motors (LIMs) are used in a significant portion of existing rail transport systems, and Bombardier Transport Canada Inc. is a global leader in the industry. LIMs will be ever more important in the future with the expansion of Maglevs globally. In this project, the intern will explore the mathematical models used in designing LIMs. The main objective will be improving the mathematical treatment in order to increase the efficiency of LIMs and eliminate or minimize undesirable effects such as overheating.
In British Columbia, highly saline waste water produced as a by-product of oil and gas operations are injected into deep geological formations via injection wells. The purpose of this research project is to investigate whether or not these injected fluids remain at depth as intended or rather, can return to the surface and contaminate water resources. In particular this project aims to evaluate the role that surrounding active and abandoned wellbores play in acting as vertical conduits for subsurface fluids to leak to the surface.
HMR-Canada has introduced magnetic liners for grinding mills that will improve the mill performance and efficiency. Mill liners have two main functions. First they protect the mill shell from wear and deliver energy to the material by lifting the material in a trajectory that creates the energy needed to break the rocks.
Magnetic liners in specific add other functions to the liners. They attract scats and magnetic minerals that form a renewable protective layer, which would increase life span of liners and shell, easier and faster to install.
In applications, such as pilot training, the cost and risk of injury can be reduced by using simulation tools. Recently, Iris Dynamics Ltd. has developed a competitively priced controller for aircraft simulation that produces force feedback on the user. Their products are currently used in both pilot training and gaming. When scaling their technology to larger forces they encounter problems of severe heating and requiring large magnets that are unsafe and difficult to handle. To solve these problems, this project will develop the mathematical theory needed for optimization of heat management.
In this project, the intern will design a community health care scheduling system for the allocation of home visits to care givers in community health care. The system adopts an agent-based distributed system architecture which take patients scheduling preferences on time, location and care givers into account when assigning care givers to home visit appointments. In addition, the system will also provide care givers with the opportunity to express their preferences and availability constraints in taking service appointments.
Current real-time precise point positioning (PPP) systems still suffer significant challenges. One is its long position convergence time necessary before precise position solutions become obtainable. Another is its sensitivity to the loss/latency of high-frequency precise orbit and clock corrections, resulting in degraded performance. Those challenges have limited PPP's adoption in many applications. This project aims to develop a fast and robust real-time PPP system.
Counting coins, with speed and accuracy, has been a challenging issue for banks and stores. People used to count coins manually before the arrival of coin counting machines. The process of counting coins manually is a very time consuming and tedious job. Moreover, mistakes are likely to occur due to various reasons such as fatigue, eye tiredness and too many coins of nearly same shape and size cause confusion in sorting and counting. Coin sorters are common in North America and can be found in most commercial banks and even some grocery stores.
Customized image sensors will be designed by EnviroSen specifically for advanced microscopes used in biomedical imaging. The goal is to develop image sensors with improved efficiency, image resolution and speed compared to existing technologies for novel microscopes for fluorescence lifetime imaging. The McMaster Biophotonics group has recently developed a novel microscope that is capable of detecting fluorescence lifetimes of biological samples with 400 times improvement in image acquisition speed.
Nowadays, there is a rapid increase in the use of Unmanned Aerial Vehicles (UAVs) for commercial and civil applications. Fully autonomous or remotely controlled UAVs requires a reliable and continuous navigation system providing meter level accuracy. The cost, size, and power demand of navigation systems providing this level of accuracy preclude their use on commercial UAVs. To provide a viable and alternative option, this research will focus on developing a navigation system for UAVs that minimizes costs, while maintaining reasonable performance standards.
Biomass combustion is used to generate combined heat and power (CHP). The combustion furnace of this study (WiseWay) has been providing heat in small scales using wood pellets. The target of this project, however, is to upgrade the stoves design (for larger scale purposes and other biomass types) and integrate it with a steam microturbine (NextGrid). The resulting system is attractive to the environment and economy because it provides heat and electricity in one package, at a cheaper price compared with oil and gas, with less pollutants emitted.
