Multiphysics Simulation of Optoelectronic Devices, Circuits and Systems

Traditionally, the microchips that power our communications technology use electrical signals to compute, transfer, and store information. Silicon photonics (SiP) is an emerging field, where structures fabricated on those same microchips replace electrical signals with optical ones, enabling exciting new applications such as optical and wireless communications, bio/environment-sensing, and computing.

Improving in-situ SVE remediation process through an integrated stochastic simulation-optimization system at the Cantuar sitea

This project is to help SaskEnergy characterize the pollutant transport behaviors under the remediation process of SVE through advanced modelling system. Such a modelling system employs a series of stochastic analysis methods to quantify the random features in the subsurface at Cantuar site such as the porosity, hydraulic conductivity and so on. Then, relationships (or functions) between SVE control variables and pollutant concentrations are generated through advance statistical methods.

External Cavity Laser Integrated with Silicon Photonic Systems

The project aims to develop a novel optical device for use in high-bandwidth data-communications. Such applications feed the insatiable desire for data transfer fuelled by the ever-expanding demand for social networking, video-over-internet and the emerging internet-of-things. The intern will gain invaluable industrial experience in a rapidly growing area, while the company will obtain an insight into the potential expansion of its product line into new applications.

Spatial and Temporal Linear Induction Motor Harmonics

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.

Investigation of possible surface contamination from a deep waste disposal injection well in Northeastern, British Columbia, Canada

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.

Study the effect of magnetic liner on ball milling efficiency utilizing DEM modelling

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.

Three-dimensional numerical simulation tool for the optimization of electromagnetic force feedback actuators

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.

Agent-based scheduling in community health care

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.

Fast and robust real-time precise point positioning

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.

Validation of a Machine Vision-based System for the Recognition of Indian Coins

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.
