In the near future, a large quantity of satellites will be used to provide Internet and communication services everywhere on Earth. Most of these satellites will be moving at very high speeds on orbits close to Earth which implies the satellites will be moving relative to a user on the ground. As a result, the links between the ground and the satellite will experience frequent disconnections; a user will be disconnected from a satellite rapidly moving out of sight and the connection will be re-established with another satellite coming into view.
This research is concerned with speaker diarization for the purpose of facilitating automated speech transcription. This problem has multiple depths depending on the prior knowledge provided to the system. The type and amount of information about the number and characteristics of the speakers can differentiate this problem in a range from a 1-to-N matching, where the voice is compared against different templates, to a clustering problem, where no prior knowledge is available.
Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. Terahertz (THz) electromagnetic waves have frequencies in the range of 1012 Hz. Terahertz spectroscopy and imaging has many applications ranging from security, communication, food production, quality control for pharmaceutical industries, and cancer diagnosis. In the heart of every terahertz spectroscopy imaging system, there is terahertz transmitter and receiver pair antennas.
Hydrogen Fuel Cell technology is actively pursued as a viable, sustainable and long-term solution for resolving transportation-related emission issues on a global scale. While Canada has a strong presence in this technology space in various parts of the world such as Europe, the USA, and China, hydrogen technology integration at the transit level is still not a reality in this country.
Blockchains operate as perhaps the most promising system of trust for any type of digital transaction of value -- everything from cryptocurrencies to patient medical records. But a number of barriers -- involving social institutions, data and identity management and technological processes -- stand in the way of broader adoption. These challenges also ultimately speak to fundamental issues of trust and perceived legitimacy on the part of both service providers and their end users.
The telecommunication industry is rapidly evolving towards providing faster services to accommodate the global surge in network demand. The next-generation (5G) network aims to increase the current network speed by more than twentyfold. This transition brings enormous benefits for the economy and society. A main challenge faced by network providers, however, is that the existing infrastructure cannot fulfill the new requirements of the 5G network. For example, the future 5G small cells need to be more powerful than the conventional 4G network architecture.
In Canada, less than 30% of the geography is covered by cellular systems. There are lots of human activities in these uncovered remote areas for either gaining nature resources or outdoor experience. In this scenario, the walkie talkie is the only and vital method helping people to build connection between each other, which can ensures their safety. Nevertheless, the signal of walkie talkie devices can be easily attenuated and/or blocked by complicated terrains such as the forest, large rock messes, and mountains.
The forthcoming 5G networks will be much more complex than their predecessors. They are on the verge of a generational transformation driven by the coverage, connectivity, availability, speed and latency demands of 5G. 5G networks will use network slicing to open up the network “as a service” to various third parties and their diversified applications, e.g., from autonomous vehicle control to massive machine-type communication for IoT devices.
Flow cytometry is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. A sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument. The sample is focused to ideally flow one cell at a time through a laser beam and the light scattered is characteristic to the cells and their components. Cells are often labeled with fluorescent markers so that light is first absorbed and then emitted in a band of wavelengths.
The research proposed in this document will build upon and extend the previously funded CRIAQ (AUT-1701) and MITACS (IT12130) projects on the development of a UAV platform for search and rescue activities in the ski facilities of Domain Saint Bernard in Mont Tremblant in collaboration with SII Canada. The goal of this research is to develop a synthesis methodology for a multivariable PID flight controller to steer a rescuing UAV to a person in danger using output feedback.
