When designing flying vehicles, there are many aspects of which we can be certain but there are also many uncertainties. Most are random, and others are just not well understood. University of Illinois Professor Harry Hilton brought together several mathematical and physical theories to help look at problems in more unified ways and solve physical engineering problems.
A study led by Chalmers University of Technology, Sweden, has shown that carbon fibers can work as battery electrodes, storing energy directly. This opens up new opportunities for structural batteries, where the carbon fiber becomes part of the energy system. The use of this type of multifunctional material can contribute to a significant weight-reduction in the aircraft and vehicles of the future -- a key challenge for electrification.
A study of dandelion seeds in motion has revealed a form of flight not seen before, and explains why the plant is among nature's best fliers.
Graphene Flagship industrial and academic partners published a new paper in Nature Reviews Materials analysing the possibilities of graphene in the internet of everything market, expected to reach over 12 billion connected devices in 2020
On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers at the University of Illinois gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the wing.
Apps that can detect what mode of transport phone users are traveling on and automatically offer relevant advice are set to become a reality after extensive data-gathering research led by the University of Sussex.
Army researchers are using metallic alloys to lighten the load and enhance the power of Soldier devices used on the battlefield. This research was recently featured on the cover of Advanced Optical Materials.
Army scientists have developed a novel algorithm that enables localization of humans and robots in areas where GPS is unavailable.
A new study, 'How should autonomous cars drive? A preference for defaults in moral judgments under risk and uncertainty,' published in Risk Analysis: An International Journal addressed this challenge by asking the public what they believed would be the most morally and ethically sound behavior for an autonomous vehicle (AV) faced with an oncoming collision. Even a perfectly functioning AV will not be able to avoid every collision and in some situations, every option will result in some type of crash.
Researchers from Chalmers University of Technology, Sweden, have now shown that studded winter tyres cost more lives than they save. The new study takes a holistic view of the tyres' impact on wider public health. At the same time, they show that their use contributes to the bloody conflict in the Democratic Republic of Congo, and fatal accidents in their production phase.
