Traditionally, the microchips that power our communications technology use electrical signals to compute, transfer, and store information. Silicon photonics (SiP) is an emerging field, where structures fabricated on those same microchips replace electrical signals with optical ones, enabling exciting new applications such as optical and wireless communications, bio/environment-sensing, and computing.
Just months the June 2014 the Supreme Court of Canada decision granting partial title to the Tsilhqotin First Nations land claim, the communities of Xeni Gwetin and Yunesitin, with support form the Tsilhqotin National Government, declared another traditional area, just beyond the granted claim, as the Dasiqox Tribal Park. The surface area of the new park contains a barrier to Tsilhqotin self-governance in the form of an undetermined amount of mineral claims staked under the mineral tenure system of British Columbia.
Regular physical activity has well known health benefits. Paradoxically, exercise can increase the risk of sudden cardiac death (SCD) in those with underlying disease. Sports-related SCDs account for approximately 90% of all SCDs. Pre-participation screening can detect underlying disease and decrease sports-related SCD. Optimal screening methods have not been universally agreed and Canadian Masters athletes are not currently required to have a cardiovascular screen before participation in sport.
Cognitive impairments are the most common long-term challenges after traumatic brain injury (TBI). There is very little research on interventions to improve cognitive function after brain injury. The goal of this project is to evaluate whether and how an intensive cognitive intervention program (Arrowsmith program) may stimulate positive changes in the brain. We have already started this program and showed that after 3 months of intervention, there were small changes in both brain and behaviour.
Hypersensitivity to sensory stimuli causes overstimulation, inducing overwhelming emotional distress in individuals with an autism spectrum disorder (ASD). Reveal is a wearable device designed by Awake Labs that monitors anxiety levels in ASD children and interfaces with parents and caregivers. It predicts behavioural meltdowns by tracking and classifying key physiological markers of anxiety using machine learning technology. However, the features between which this model is trained to differentiate were developed ad hoc, and built from data that was collected from adults without ASD.
Research suggests that individuals with autism live a lower quality of life than their peers. Individuals with autism are more likely to become obese than their typically developing peers, and less likely to develop friendships and be involved in their communities. While physical fitness service providers are experts in physical fitness, working with individuals with autism can require additional teaching skills. This study will investigate the effectiveness of instructor implemented Positive Behaviour Support for young adults with autism in a physical fitness program.
Hydrogen fuel cells require humidification in order to operate effectively, yet, at the same time produce a constant stream of moisture through their exhaust. Membrane fuel cell humidifiers provide a method of recycling this moisture, thereby saving energy. They work similarly to heat exchangers, but take advantage of special polymer membranes in order to exchange moisture. Fuel cell environments can be very taxing on membranes, reaching temperatures of 95C, so selecting the right membrane material is of utmost importance.
HMR-Canada has introduced magnetic liners for grinding mills that will improve the mill performance and efficiency. Mill liners have two main functions. First they protect the mill shell from wear and deliver energy to the material by lifting the material in a trajectory that creates the energy needed to break the rocks.
Magnetic liners in specific add other functions to the liners. They attract scats and magnetic minerals that form a renewable protective layer, which would increase life span of liners and shell, easier and faster to install.
As computer chips approach the nanometer-scale size, it is becoming increasingly clear that the next revolution in computing technologies will be enabled by quantum computing. A pioneer in quantum technologies aimed at quantum computing, the Canadian company D-wave Systems has developed quantum annealing processors consisting of superconducting circuit that can be used as efficient devices for solving high-dimensional optimization or sampling problems. The same problems can be solved using conventional computers and it is not yet clear if quantum annealers offer quantum speedup.
