An influx of plug-in electric vehicles (PEVs) charging without coordination could prove challenging to the nation's electric grid, according to research conducted by the US Department of Energy's National Renewable Energy Laboratory (NREL).
New research led by WMG, at the University of Warwick has found an effective approach to replacing graphite in the anodes of lithium-ion batteries using silicon, by reinforcing the anode's structure with graphene girders. This could more than double the life of rechargeable lithium-ion based batteries and also increase the capacity delivered by those batteries.
Developed by UZH researchers, the algorithm DroNet allows drones to fly completely by themselves through the streets of a city and in indoor environments. Therefore, the algorithm had to learn traffic rules and adapt training examples from cyclists and car drivers.
In a paper published today in Small, researchers at the University of California, Riverside, describe the development of an inexpensive, efficient catalyst material for a type of fuel cell called a polymer electrolyte membrane fuel cell (PEMFC), which turns the chemical energy of hydrogen into electricity and is among the most promising fuel cell types to power cars and electronics.
'The beauty of this research is that someone using only a laptop and an object that flickers can detect if someone is using a drone to spy on them,' says Ben Nassi, a Ph.D. student in the BGU Department of Software and Information Systems Engineering and a researcher at the BGU Cyber Security Research Center (CSRC). 'While it has been possible to detect a drone, now someone can also tell if it is recording a video of your location or something else.'
Drivers' limited capacity to process the myriad details they absorb could explain why they sometimes fail to avoid crashes with motorcycles.
In a new paper appearing in IEEE Access, members of the Camera Culture group at MIT's Media Lab present a new approach to time-of-flight imaging that increases its depth resolution 1,000-fold. That's the type of resolution that could make self-driving cars practical.
The idea of driverless cars continues to make headlines across the world, including the recent revelation that researchers don car seat costumes to observe how the public interacts with cars that appear driverless. Despite the apparent absurdity of such research techniques, driverless cars are approaching the on ramp to reality. A team of researchers have proposed an integrated framework to help cars interact without the human touch--quite literally.
As cars become more fuel-efficient, less heat is wasted in the exhaust, which makes it harder to clean up the pollutants being emitted. Researchers at The University of New Mexico (UNM) and Washington State University have created a catalyst capable of reducing pollutants at the lower temperatures expected in advanced engines.
Brazilian researcher develops innovative method of laser welding at high temperatures that enhances properties of AHS steel for applications in automotive and aerospace industries
