Two B-25 bombers associated with American servicemen missing in action from World War II were recently documented in the waters off Papua New Guinea by Project Recover -- a collaborative team of marine scientists, archaeologists and volunteers who have combined efforts to locate aircraft and associated MIAs from World War II.
Significant commercial investment in wearable vision systems for personal communications and entertainment is driving rapid advances in miniature optoelectronics components and consumer-driven applications. A special section in this month's issue of Optical Engineering, published by SPIE, the international society for optics and photonics, aims to help boost progress across development in automotive, industrial, and military applications.
Engineers have known for some time that calcium chloride salt, commonly used as deicer, reacts with the calcium hydroxide in concrete to form a chemical byproduct that causes roadways to crumble. A civil engineer from Drexel University is working on a new recipe for concrete, using cast-off products from furnaces, that can hold its own against the forces of chemical erosion.
NRL researchers at the Vehicle Research Section and Photovoltaic Section are building on the proven concept of autonomous cooperative soaring of unmanned aerial vehicles (UAVs), which enables long endurance flights of unmanned sailplanes that use the power of the Sun.
The presence of just a few autonomous vehicles can eliminate the stop-and-go driving of the human drivers in traffic, along with the accident risk and fuel inefficiency it causes, according to new research. The finding indicates that self-driving cars and related technology may be even closer to revolutionizing traffic control than previously thought.
A study recently published in the SPIE Journal of Photonics for Energy demonstrates how to convert a luminescent solar concentrator into an energy-harvesting laser phosphor display by projecting intensity modulated light. The journal is published by SPIE, the international society for optics and photonics.
Researchers at NRL have developed a breakthrough alternative to fire-prone lithium-ion batteries.
Advances in wearable technology offer new possibilities for in-vehicle interaction but also present new challenges for managing driver attention and regulating device use in vehicles.
Driverless cars are hitting the headlines across the globe but for the foreseeable future we will still have drivers. The pressure then is how might some of the safety features of driverless cars be incorporated into conventional vehicles? Writing in the International Journal of Vehicle Autonomous Systems, researchers from India describe a real-time automatic obstacle detection and alert system for driver assistance.
Turbulence strong enough to catapult unbuckled passengers and crew around the aircraft cabin could become twice or even three times as common because of climate change, according to a new study from the University of Reading published in Advances in Atmospheric Sciences.
