Microwave Imaging (MWI) is an emerging modality where the goal is to estimate the electrical properties of an object-of-interest. This is done by transmitting a microwave signal into the OI and collecting measurements outside the OI. The measurements are inputs to an optimization algorithm that solves for the unknown electrical properties. It has been proven using computational techniques that the proposed modality can be successfully adapted for monitoring moisture content inside grain bins.
The existing technologies used for monitoring the voltage and the electric field in the vicinity of the high voltage devices are bulky and expensive. On the other hand, maintenance of the monitoring devices requires specific safety precautions. In this research project, a small and inexpensive electric field sensor is proposed. They are passive and require no source of power. This eliminates the need of changing the batteries and direct contact to the high voltage apparatus. The interrogation system will be wireless that makes the distant measurement possible.
The aim of the proposed research cluster is to advance the state of the art of secure operation of power systems by developing new methods and tools. A power system is expected to perform within specified operating boundaries of system voltage and frequency under normal conditions when there are no component outages. Further, it should also be able to deliver the same performance under single outages that are most likely to occur. Two ways of advancing the state of the art will be addressed in this research cluster.
A cross-disciplinary collaboration between investigators in Electrical Engineering and Chemistry has lead to the discovery of a promising new material system for nanoelectronics. This material system is a conducting polymer / inorganic metal oxide heterojunction, electrochemically grown onto a crossbar structure. This heterojunction produces transient current-voltage characteristics that can be controlled by electric fields and exhibits memory effects.
This innovative system will allow for highly controlled quantitative data, which will provide efficient cell migration analysis. The research is important because it reveals the underlying mechanisms behind the process of wound healing and other vital cell functions.
Song’s internship in Canada has provided him with hands-on experience that offered insight into a research field that he intends to pursue in graduate studies.
A wireless sensor has been designed to monitor overhead line temperature. The economic importance of this issue is to maximize the power transfer capacity of the lines. The sensor has two main parts, a local interrogator and a passive battery-less sensor. The power to turn on sensor comes from interrogator. The sensor measures the temperature, and transfers the data to interrogator for signal processing. The measurement accuracy of the sensor is reported to be about 0.07°C. There are some sources of error in sensor measurements.
Computer attacks such as viruses, Trojans, etc. are a continuous problem for governments, companies, and individuals. The most common methods of detecting these computer problems like anti-virus systems rely on an attack being known and described before it can be detected. This opens a hole in computer security systems for new attacks that have not yet been detected. This project focuses on the use of mathematics and advanced anomaly detection algorithms to determine 'normal' and 'abnormal' behavior on computer networks, and attempts to detect attacks by detecting 'abnormal' behavior.
Daniel comes to Canada from Guadalajara, Mexico’s Instituto Tecnológico y de Estudios Superiores de Monterrey’s Department of Biotechnology engineering on a 12-week Mitacs Globalink internship. Under the guidance of Dr. Peter Eck, from the Department of Human Nutritional Sciences, he is contributing to research on the genes implicated in complex chronic diseases such as Type 2 Diabetes.
The proposed project is dedicated to fast resistance and inductance extraction for multiconductor transmission lines. Since the complexity of power cable designs has grown significantly over the past decade, fast and accurate tools for electromagnetic characterization are required. The cable models presently used by Manitoba Hydro however are overly simplified compared to the ones available on the market. The alternative surface-volume-surface integral equation formulation is proposed to reduce computational time and memory.
Buhler Versatile Inc. (BVI) is in the process of making design improvements to its air seeding equipment. The intern will be tasked with completing an ergonomic evaluation of the air seeder control system, with specific emphasis on the design of the displays used to provide information to the air seeder operator. Proposed modifications to the existing displays will be based on situation awareness design principles.
