Data-Over-Cable Service Interface Specifications (DOCSIS) 3.1 is a technology that utilizes orthogonal frequency-division multiplexing (OFDM) technology to provide downstream (DS) transmission capacities of up to 10 gigabits per seconds (Gbps), as well as orthogonal frequency-division multiple access (OFDMA) technology to provide upstream (US) transmission capacities of up to 1 Gbps per channel. Full duplex (FDX) communication, via the concurrent transmission of the US and DS on the same frequencies, has been proposed for boosting the US capacity.
High frequency millimeter-waves are quickly becoming essential for many industrial and commercial applications including high resolution automotive radar and high-speed wireless communication systems. While millimeter-waves offer many benefits, they also introduce new engineering challenges, due to the smaller wavelengths and dielectric properties of materials at high frequencies. One of the primary challenges relates to the accurate characterization of the substrate material parameters, which are relied heavily upon in design and simulation of millimeter-wave circuits.
In collaboration with Western Canada Realty, we aim to develop a real-estate valuation online service for the Alberta real-estate market, especially for Edmonton. The product resembles Trulia and Zillow on a high level, which are real-estate price estimation web services in U.S. The system requires a backend that takes as input house pricing information from several sources including real-estate property assessment publicly available from the City of Edmonton website and recent house transaction records on MLSÂ®.
Rapid growth of renewable energy generation and DC loads as electric vehicles and consumer electronics results in the proliferation of DC microgrids. DC microgrids are small electrical grids where energy sources and loads are connected to a main energy distribution power line using power converters.
The use of garbage trucks with ârobot armsâ for municipal waste collection is becoming more and more common in Ontario and across North America. However, these ârobotsâ have very little capability. In our collaboration with Waterloo Controls, we are working to automate the process of garbage collection. Rather than requiring the operator to acquire the truck, then steer the robot arm to pick up the bin, we are working to add automatic capability.
We aim to develop a video surveillance system that detects and reports events of interest to users. Traditional way is to use RGB cameras to operate in constantly and evenly illuminated areas to detect simple events. The challenge is that visual characteristics of an unconstrained scene are unstable due to illumination variations. In this project, by using RGB-D cameras, 3D position information of humans can be obtained, which is robust and insensitive to the illumination variations.
Two High Voltage DC (HVDC) transmission technologies, the mature Line Commutated Converter (LCC) and newer Voltage Source Converter (VSC) technologies have their own pros and cons. For a HVDC transmission system carrying power from a single generation center to multiple load centers, by using a multi-terminal LCC-VSC type hybrid HVDC configuration, advantages of both technologies can be exploited. There is also the possibility of tapping into existing point-to-point LCC transmission lines using this hybrid configuration to supply intermediate locations.
Internet of Things (IoT) is a topic that many enterprises including Ericsson are pursuing to find innovative ways of providing a better and futuristic service to the clients. The large amount of CapEx and OpEx related to IoT infrastructure deployment and operation and humongous amount of data generated by IoT devices on the edge and in the center demands creative ways of sharing the IoT infrastructure between clients and effective ways of transferring/handling the generated/processed data.
Since the adoption of the North American Free Trade Agreement (NAFTA) signed on January 1st 1994, the amount of truck freight moved between Canada, U.S. and Mexico has increased considerably. However, the transportation of goods has still have some gaps that need to be settled such as loss of merchandise and delay in delivery time. The reason of these gaps is due to the involvement of several participants in the transportation loop. The delivery of products from the manufacturers to the retailers is done through asset based carriers (55%) and owner operators (45%).
The field of plastic waste management is essential for sustainable society that utilizes plastic waste for energy production. Land filing and incineration of plastic waste has large environmental impacts due to GHG emissions. Thus, pyrolysis is considered a low environmental impact process with high value end products. RF thermal plasma technology will help reduce operating cost, cleaner thermal source, shorten reaction time and provide high quality hydrocarbon gasoline and diesel.
