Development of MEMS auto-focusing mechanism for cell phone cameras

Micro-electromechanical systems (MEMS) refer to integrated mechanical & electrical systems in micron scale that are now growing in numbers due to a miniaturization trend. An advanced actuation method proposed for MEMS in University of Toronto and Ryerson University will be applied for an auto-focus mechanism in cell phone cameras. This research will build on work conducted by a six-member research team in both universities. The proposed MEMS autofocus not only has larger depth of focus, but also is faster than the current technologies, and is easier to implement.

Computational modeling of Magnetic Nanoparticles for Ultrasound Detection and Targeted Hyperthermia of the Sentinel Lymph Nodes

Breast cancer tumors spread to the rest of the body through the sentinel lymph nodes (the first lymph node to receive lymphatic drainage from a tumor). The metastases of breast cancer can be controlled by the detection and removal of these nodes.  The surgical removal of the auxillary lymph nodes and perform biopsy tests is the only reliable way to detect and remove the nodes.  This procedure can result in significant morbidity.

Sustainable Development through the Effective Production and Use of Bio-Fuels and Integrated Bio-Refineries

The project concentrates on developing a holistic approach to integrate bio-refinery with multiple feedstocks. The proposal is directed towards the use of all types of renewable raw materials except food. The project examines the possibility of retrofitting an existing petroleum refinery and petro-chemical complex into integrated bio-refinery to emphasize the utilization of existing infrastructure for bio-fuels; bio-products and direct bio-energy production.

Development of Tall-Structure Lightning Return-Stroke Current Modelling for Lightning Protection of Wind Turbines

The lightning return-stroke is the vital component of a lightning flash since it causes most of the lightning-related damages/disturbances to electric power lines and installations. This research emphasizes the development of a lightning return-stroke model in order to analytically correlate the lightning current, usually measured at a tall structure, to its associated lightning electromagnetic pulse (LEMP).

Passive Dampers in Elevated Tanks for Mitigating the Effects of Wind and Seismic Loads in New and Existing Structures

The objective of the proposed R & D project is to recommend a methodology for using tuned liquid damper as a passive damper placed in elevated tanks. A portion of contained liquid can be utilized to act as a tuned liquid damper with some modifications. This methodology can be used to control displacements due to wind and earthquake effects. A numerical program using the finite element method is proposed, which will be conducted to simulate a structure with a TLD attached and subjected to transient loading. The results of this study will be applied to elevated tanks.

Demonstration and Performance Evaluation of an Optimized Lab-scale Biogas-fuelled Heat and Electric Power Generation System Based on the Solid Oxide Fuel Cell

The build of an efficient, low cost, and environmentally friendly heat and power generation system for the use in single family detached dwellings, wastewater treatment plants, or landfills, is the objective of this project. This system is based on the solid oxide fuel cell and is designed to operate with biogas. We have successfully proved the advantages of this system over the traditional and other fuel cell-based systems developed in the United States and Europe, through computer simulation.

Development of Framework for Integrating Smartphones for Transportation Information Applications

Recently, a new kind of cell phones known as “smartphones” is introduced and sold to the public in great numbers. A smartphone generally refers to a cell phone that is capable of communicating through the internet (via wireless internet or data network), determining its current positions (with Global Positioning System, GPS), and taking photos (with high resolution cameras) in addition to the classic voice communications. Most smartphones are also equipped with touch screens that provide a user-friendly intuitive interface.

Multivariate Feature Extraction Methods for Biomedical Signals and Health Data Classification

In large health data sets, researchers may want to classify individuals into important groups, such as risk groups, based on multiple important variables from various different data resources.  Different groups may warrant different, targeted interventions.  Combining different data sources to classify individuals with the highest risks and needs can provide health officials an objective way of targeting scarce health care resources.  Since each individual would have variables from multiple data sources, determining the key features that can be used to classify individuals into groups requi

Intraoperative Surgical Guidance for Neurosurgical Applications

Current intraoperative surgical navigation techniques are time consuming, may involve radiation and most importantly, are only able to account for patient motion during surgery a few times. The research project will focus on the development of an optical imaging device capable of capturing topographical images of exposed anatomical structures within the surgical field. These images in combination with CT and MRI data will guide the surgeon in the placement of devices such as screws within the spine.

Modelling of integrated biomass gasification and solid oxide fuel cell systems

Integrated solid oxide fuel cell and biomass gasification systems are one of the most promising energy technologies of the future. Usage of this system to utilize biomass yields better performance and environmental impact compared to the conventional biomass utilization technologies, e.g. steam turbine and internal combustion engine. However, to get the most benefit from this system, the configurations and operating parameters of this system should be optimized, which can be done through modeling.
