Evaluation and Improvement of High Voltage Module (HVM) of X-ray Generator - Year two

The motivation for this research comes from an overall need to improve the performance of high voltage module (HVM) and to reduce the size and its material costs while maintaining its efficient performance, with no partial discharge, arc or thermal issues. In particular, stable transient and steady state performances must be achieved for medical X-generators under wide load variation, ranging from 40-150 kV output voltage and 0.1-1000 mA output current to obtain defect free images. The desired HV module will combine the optimum cost-effective design with compactness.

Control Scheme for Smart Combiner in Large-Scale Solar Farms

The smart combiner is a new device which can help increase the energy yield of large solar farms. However, its control system needs to be well designed. This project aims at developing a new control scheme to best utilize the ability of smart combiners, increasing energy yield while ensuring control accuracy and good dynamics. To reach this goal, an emerging control technology, model predictive control, will be adopted and designed to achieve a high-performance control system for smart combiners.

Design of High-performance LDPC-based Forward Error Correction Codes for Fiber Optic Communications Systems

As time goes on, we observe a significant growth for the high-speed error-free communication systems. This requires that the optical networks, as the major carrier for data transmission, increase their capacity to meet the current needs of the telecommunication industry. Forward error-correcting (FEC) codes, as the most effective solution to enhance the quality and reliability of data transmission, have been adopted in optical communication systems.

Environmental DNA samplers for aquaculture decision making

We propose a research project that explores lab-on-chip microfluidic technology for transformative gains in wet-chemistry handling for environmental DNA samplers applied to the aquaculture space. We anticipate that our lab-on-chip sampler will reduce instrument size and cost, while improving sample integrity through automation and fluidic integration. We believe that such an eDNA sampler would find broad applicability beyond our initial use case of aquaculture.

Development of Electronically Tunable and Fixed Filters for TVWS and 5G Wireless Systems

TV Whitespace (TVWS) designates the inactive or unused space between TV channels actively used in UHF and VHF spectrum :470 MHz to 700 MHz. The TVWS band performs best in the most rural service areas. This is due to the characteristics of TVWS, and how it's shared with powerful analog TV stations Such TV transmitters can have up to hundreds of kilowatts of transmit power creating strong interference. Due to spectrum sharing with these powerful analog TV stations the reliability of wireless communications in TVWS is affected.

Reducing the effect of magnetic disturbance in inertial measurement based indoor localization

Using inertial measurement units (IMUs) has been one of the main techniques for indoor localization. In many cases, this type of methods uses accelerometer, gyroscope, and/or magnetometer that are available in commercial mobile devices, such as smart phone. One main advantage of using this type of techniques is that no separate infrastructure deployment is needed. However, its performance is affected by noise that exists in the measurement data. When tracking pedestrians, the moving speed and direction are usually estimated separately. Muldi Vision Ltd.

Implementation of Photonic Computing Chip (IPCC)

The IPCC project aims to utilize the advancements in lasers, optics and semiconductor fabrication facilities to deliver a computing chip that uses laser instead on electrical signals to perform computations. The new paradigm of computation execution allows computations to be performed much faster at lower energy consumption which directly leads to lower costs for computations. The advantage is particularly huge for AI computations. The Interns will perform research work to design, fabricate and test the new chip and develop software that allow using this chip efficiently.

Multiplexed POCT detection of inflammatory biomarkers for disease diagnosis and stratification

The local and global prevalence of infectious diseases require plenty of healthcare resources. Accurate and on-time diagnostic information is of critical value for appropriate patient treatment and healthcare resource management. Typically, single biomarker testing results are not sufficiently sensitive and specific to achieve the high accuracy of diagnosis and stratification. Testing multiple biomarkers (e.g. inflammatory markers) may significantly improve the sensitivity of diagnosis and the efficiency of clinical decision-making processes.

Design Energy Harvesting Circuit and its System-on-Chip Implementation

We have seen the acceleration of global warming in recent years. Green-energy powered electronic devices are more desirable. In this proposal, we propose to develop an energy harvesting circuit and implement it on a system-on-chip. The design goals are low-cost, user-friendly, and portable. By partnering with Hidaca Ltd., our ultimate goal is to have this made-in-Canada technology available on the market as soon as possible to benefit Canadians and the global population.

Schedulability Analysis of Real-Time Systems Using Metaheuristic Search and Machine Learning

Schedulability analysis aims at determining whether task executions complete before their specified deadlines. It is an important activity in developing real-time systems. However, in practice, engineers have had difficulties applying existing techniques mainly because the working assumptions of existing methods are often not valid in their systems. Specifically, uncertainties in real-time systems and hybrid scheduling policies that combine standard scheduling policies have not been fully studied in the literature.
