A report describes approximate solutions for surface temperature and heat flux for two embedded temperature sensors. The solutions were verified and the range of validity was established using several methods including comparisons with an exact analytical...

A document describes experiments performed to investigate rates of delivery of energy onto targets from different explosive formulations. The experiments were designed to measure relative positions of blast fireballs and leading shock fronts; determine whether different explosive formulations exhibit...

The internal mechanism of the connector part of this system works to maintain positioning repeatability and rigidity, and compensates for wear over time, while both the connector and receiver are tapered in two planes to assure repeatable positioning. Together, the two form a rigid connection that can...

Shape Memory Alloys (SMAs) are metals that “remember” their original shapes. SMA technology can provide the same mechanical movement and required forces of an electromagnetic actuator, but in a more compact form, while removing the need for motors, gearing, or springs. This SMA...

A company seeks technologies enabling a woven or nonwoven substrate to contain liquid/fluid that can be released by applying pressure (to yield a moist/wet substrate). They are interested in solutions that will enable water or other liquids/ fluids to be contained within a substrate and then released under moderate...

Binders used for molding are typically self-setting, so that after mixing two or more binder components into sand, there is a short delay before the mixture starts to set hard. Binders used for core-making are typically gas-cured. A company seeks an environmentally...

There’s no shortage of solutions proposed to solve the problem of global warming, some devised after long, painstaking, and expensive hours of research. But President Obama’s key energy expert has come up with what appears to be a low-cost no-brainer - paint the roofs of all buildings white. According to U.S. Secretary of...

Much of the attention during the current space shuttle mission has focused on making long-awaited repairs to the aging Hubble Space Telescope. But there are other matters to attend to as well. Such as tasting water recycled from urine. On Wednesday, astronauts aboard the International Space Station conducted the first taste test of an...

Earlier this week the space shuttle Atlantis took off from NASA’s Kennedy Space Center on the fifth – and what is said to be final – repair mission to the Hubble Space Telescope. Launched in April 1990, Hubble has produced some spectacular images over the years, greatly expanding our knowledge of the universe well beyond...

Star Trek aficionados will once again get to see their beloved Starship Enterprise traveling at warp speed – the speed of light - when the latest Star Trek movie opens in theatres today. While 'warp speed' has long been associated with the long-running science fiction entertainment series, the concept remains a pipe dream...

Tornadoes are fast-moving but deadly events, able to carve out a wide path of destruction in just seconds. Now, scientists from the National Center for Atmospheric Research and other organizations hope to get a better handle on how and why tornadoes form, by launching what is reportedly the largest and most...
