Al applications require massive computing resources that consume immense energy. Al compute is expected to account for a significant percentage of the global power consumption. As current digital Al chips cannot keep up with demand, more energy-efficient Al chips are required.This project addresses major milestones toward implementing an energy-efficient photonic Al accelerator system.
The overall purpose of this research is to measure the effect of lower extremity muscular fatigue and bracing on the hip, knee, and ankle joint biomechanics in two different populations; i) those at risk of ACL injury and ii) those with early onset osteoarthritis.
Canada, in general, and BC, in particular, is in the melting pot when its territory starts to experience a range of unprecedented multi-hazards such as floods and earthquakes, among others. Climate change, being the key cause, has increased the uncertainty, intensity and frequency of such hazards. As a consequence, the continuous defective separator (CDS) system, a unique hybrid technology to effectively separate suspended solids, hydrocarbons and trash from stormwater runoff, will suffer hydraulic overloading due to the overflow during peak hours or high rainfall events.
Detecting the presence of bacteria at a low concentration during a wound healing process can eliminate catastrophic results such as chronic infection and amputation. The available diagnostic techniques with high sensitivity require high-tech equipment and are expensive. Moreover, to monitor the wound with these kits/technologies, wound dressing removal is needed, which causes the second trauma. In order to overcome these shortcomings, we are fabricating Nanosheet™ Biosensor.
Capturing high quality images is a major selling point of modern flagship smartphones. However, due to physical constraints on sensor size, capturing a good image with a mobile phone is challenging especially in low-light conditions. To obtain a bright image, one has to use a long exposure or digitally gain up a short exposure image. The former will result in blurry images due to handshake and scene motion, and the latter will yield noisy images. We will explore methods that combine complimentary information from both types of images captured from two separate cameras synchronously.
The proposed research project aims at technology for environmentally benign recycling of nickel. The process entails conversion of nickel found in the "black mass" from recycled Ni-based batteries into nickel carbonyl, Ni(CO)4, by reaction with CO at modest temperatures around 50-120°C (pressuredependent). Only nickel carbonyl is volatile under these conditions and is easily separated from other metals and residual materials found in the "black mass". Downstream, the nickel tetracarbonyl vaporsare introduced into a high-temperature zone (ca.
Heat stress is a deadly occupational hazard that is projected to increase in severity with global warming. While upper limits for heat stress designed to protect all workers have been recommended by occupational safety institutes for some time, heat stress continues to compromise health and productivity. The continuing detrimental effects of heat stress may be partly explained by the inability of existing guidelines to consider individual factors (e.g., age, sex, health status, work duration) that can modify an individual’s tolerance to a given heat stress.
Electric machine condition monitoring and control techniques are being widely investigated for electric vehicle applications, which are essential to ensure high performance, efficiency, and reliability in electric traction drive system. However, the testing and validation of these techniques are challenging and have not received enough attention. Thus, the research project aims to propose new testing methodologies for validation of electric machine condition monitoring and control techniques to fill this knowledge gap in electric machine field.
Rappelon is robotic platform that works at heights on vertical surfaces. The robot can pass obstacles and working on facades with complicated geometries. With this robot, some dangerous and laborious tasks can be automated. They include highrise window cleaning, water tank painting and wind turbine blades maintenance. This project focuses on developing algorithms to keep the robot stable and make it move in different directions.To this end, analytic models as well as computer software will be developed to predict the position of each component, forces and loads on the building.
As the heat fluxes produced by modern high-performance microprocessors continue to rise, so too must the effectiveness of the removal of these fluxes. Accordingly, a large amount of research has focused on developing techniques to enhance cooling in computer systems. A novel method of doing so involves replacing the single-phase liquid or two phase-liquid vapor coolants typically employed in such systems with binary fluid mixtures.
