3D concrete printing and the digital design processes associated with this technology are developing quickly across the world, both in academia and in practice, moving from the realm of the artisan to the early stages of automated manufacturing.
How do architects engage this emerging new field that combines fabrication technologies with material in their design processes? Emerging use of ultra-high-performance concrete (UHPC) creates designs without steel reinforcing in thinner structures by using fine sand and integrated fibre reinforcements.
With the development of industry, more and more energy consumption has brought about a huge crisis. The development of renewable energy technologies, such as photovoltaic equipment, offers new hope for solving energy problems. Solantro SFnG has been developed and operated in the company’s lab for about 5 years. This real-life nanogrid contains PV panels, energy storage units, a variety of loads and the micro-chip controller.
The COVID-19 pandemic is a rapidly evolving, dramatic health crisis. Daily, the numbers are rising of people infected with, and killed by, the novel coronavirus. Due to physical distancing measures put in place to slow the spread of the virus, there are unprecedented work/life situations for thousands of Canadians, particularly those who are faced with the challenge of working remotely while providing care to their children and dependents such as elderly parents.
Massive drifting icebergs frequently threaten offshore operations on the Grand Banks because of their massive size, and great mechanical strength. These ice hazards move erratically, which complicates efforts to modify their trajectory or undertake evasive action. This MITACS project aims to further improve security of offshore workers and help protect wildlife and the environment by allowing refined prediction of short-term iceberg drift. The funding partner, ASL Environmental Sciences, will benefit through improved capability to provide world-class services to their clients.
Coffee production with imported beans has doubled in Canada since 2003. From this > 125,000 t of waste is generated most of which ends up in landfill. A significant component of the waste is as the pulp (cascara) and silverskin. In 2019, the Happy Goat Company roasted 50 t of green coffee beans yielding 300kg silverskin which will greatly increase in 2021. Silverskin teas have 3-6 times more caffeine than coffee beans and are rich in total phenolics, antioxidant capacity and phytosterols. There is good evidence of their safety.
Physical inactivity is a growing global health crisis, with childhood physical inactivity being of particular concern. The Global Matrix 4.0 Physical Activity Report Cards for Children and Youth is an initiative aimed at promoting global childhood physical activity through international collaborations. The goal of this project is to further the global promotion of childhood physical activity by contributing to the development of the Global Matrix 4.0.
The advent of 5G (fifth generation) telecommunication networks also brings new security challenges, in addition to many benefits to the community. Such is exemplified by its special nature of technology (as well as the new business model) and its deep involvement in people’s everyday life, hence more critical. We need proper security metrics to tell how secure these new networks are especially for decision makers. Our preliminary studies show that existing security metrics are insufficient for 5G networks (as they are not designed so).
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.
