Cornell University researchers are expressing hope for the future of Houston's breathable air, despite the city's poor rankings in the American Lung Association's 2019 'State of the Air' report. The report, released in April, ranked Houston ninth nationally for worst ozone pollution and 17th for particle pollution. Researchers say replacing at least 35 percent of Houston's gasoline cars and diesel trucks with electric vehicles by 2040 will reduce pollution and improve air quality by 50 percent.
A team of roboticists at Harvard's Wyss Institute for Biologically Inspired Engineering, the Harvard John A. Paulson School of Engineering and Applied Sciences, and MIT has developed a new way to design pistons that replaces their conventional rigid elements with a mechanism using compressible structures inside a membrane made of soft materials. The resulting 'tension pistons' generate more than three times the force of comparable conventional pistons, eliminate much of the friction, and at low pressures are up to 40 percent more energy efficient.
Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less than half as much. The finding means that vehicle designers will be able to develop lighter military vehicles without sacrificing safety, or can improve protection without making vehicles heavier.
A group of scientists in USA has developed the first-ever standardized method of evaluating commercially available driver-monitoring systems. The researchers hope to use their method in a more complex way by incorporating more factors and looking at more scenarios. These include a lighting device that could be used in the lab to simulate real light conditions as well as a few other sites that could enhance the method's accuracy and efficiency even further.
A group of American and Chinese researchers has designed and tested a microgrid system that is both robust and reliable -- and therefore capable of delivering energy safely and without interruptions. This is particularly important during harsh weather conditions and times of peak consumption and is critical for economic growth.
Southwest Research Institute (SwRI) has announced the release of ActiveVision, a machine vision tool that transportation agencies can use to autonomously detect and report traffic condition changes. ActiveVision's algorithms process camera data to provide real-time information on weather conditions and other anomalies affecting congestion. Designed for integration with intelligent transportation systems (ITS), ActiveVision can be configured with existing traffic cameras to analyze roadway conditions with no human monitoring required.
Control engineers and AI experts team up to make drones that fly more smoothly close to the ground.
Aluminum is one of the most promising materials for aeronautics and automobile industry. Scientists from the National University of Science and Technology 'MISIS' found a simple and efficient way of strengthening aluminum-based composite materials. Doping aluminum melt with nickel and lanthanum, scientists managed to create a material combining benefits of both composite materials and standard alloys: flexibility, strength, lightness. The article on the research is published in Materials Letters.
University of Washington researchers have developed a novel solution to help reduce impact forces -- for potential applications in spacecraft, cars and beyond.
With aims of bringing more human-like reasoning to autonomous vehicles, MIT researchers have created a system that uses only simple maps and visual data to enable driverless cars to navigate routes in new, complex environments.
