Imagine using unattended ground sensors to provide continuous weather reports and surveillance of critical targets in enemy areas. The Defense Department thinks the idea is sound enough to pursue. The agency includes it among nine projects it will fund this fiscal year under its Advanced Concept Technology Demonstration (ACTD) program. The other projects are: a networked early warning system for biological threats, a method for detecting coordinated attacks on computer networks, a "joint continuous strike environment" using combined suites of weapons on targets, a system for moving weapons and other materiel from ship to shore in heavy seas, an interface between major tactical data links on the ground and in the air, an advanced forward looking infrared system for precise target location and identification, a markedly improved capability for precise counterfire at the battle-theater level, and a line-of-sight system for high-speed destruction of many tanks at once.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
Anyone who’s ever moved files from a hard drive to a computer has sat patiently waiting for the transfer to complete. But what if this process could be done wirelessly, without having to connect devices with cables, and in seconds?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
