Measurement Optimization for Localization using Modeled Radio Maps and Compressive Sensing

Location information is an important enabler for context-aware services and communication system improvement. Localization can be performed by comparing the power readings of all surrounding wireless transmitters to a database of these readings at all possible locations, known as the radio map. For this localization process to work, the system requires accurate radio maps. Our industrial partner, Siradel, have designed a software to create modeled estimates of radio maps for any site, which need to be refined with measurements.

Innovating Computing Devices

In general, if a user is not willing/able to implement himself the solution, attaching sensor and actuator equipment to a computer typically leads to disproportionately expensive  purchases of proprietary hardware or software, which often still requires a considerable time investment. The goal of our planned company is to provide affordable computer-attached electronic equipment to individuals and businesses worldwide. Our devices will: (1) perform data acquisition and control of external hardware, i.e. input/output (I/O) operations; or (2) speed-up compute-intensive calculations.

Cooperative Wireless Cellular Networks: System Design, Analysis and Simulation

The ever growing market demands for higher data rates and more reliable communication are the main drivers behind the technological growth in the wireless telecommunications industry. This R&D project aims to address an innovative technological shift from conventional wireless cellular networks to a paradigm of cooperative cellular networks that can potentially provide multiple-fold improvements in terms of the total data rates.

Integrated Pulse Shaping Devices

Pulse shaping devices are the key elements for optical signal processing that are capable of reshaping the temporal waveform of optical pulses.  The applications of pulse shaping devices include ultrahigh-speed optical telecommunication, ultrafast all-optical computing and information processing, biomedical imaging, and electronic and photonic signal/device characterization and monitoring. For these applications, ultrafast optical waveform shapers capable of synthesizing temporal waveform features down to the sub-picosecond regime are required.

Heterojunction colloidal quantum dot based solar cells

Solar power is one of the most promising renewable energy sources and its terrestrial abundance is several orders of magnitude higher than world’s consumption. Conventional solar cells, however, collect only a portion of solar energy – mostly visible sunlight. Our technology is capable of collecting the entire solar energy spectrum by using semiconducting nanocrystals (NCs) as the photovoltaic material.

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).

Conductivity measurements of cardiac tissue using magnetic resonance imaging

The first objective of this project is to obtain the first high resolution impedance measurements of cardiac tissue. These measurements will be synchronized with electrocardiogram to determine quantitatively for the first time the changes of conductivity at different stages of the cardiac cycle. Since the heart is one of the most electrically-active areas inside human body, knowledge of its electrical properties will benefit many cardiac modeling and clinical applications. The second objective of this project is to test the influence of anisotropy on cardiac impedance imaging.

Monolithic Integration of Sheath-less Piezo-resistive Pressure Sensor with Volume Conductance Catheter

Scisense is a medical device company focused on Micro Sensor technology used to monitor cardio dynamics in animals as small as mice. Scisense's existing production process l-Or building the micro sensor probes is a tedious process that requires a high degree of skilled labour and ultimately results in a low yield of marketable devices. The company's growth is limited by this yield potential.

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.
