People give instructions at varying levels of abstraction -- from the simple and straightforward ("Go north a bit.") to more complex commands that imply a myriad of subtasks ("Take the block to the blue room."). A new software system...
Tim Koehler, a Sandia National Laboratories mechanical engineer, is using computational fluid dynamics modeling to help the Santa Fe, New Mexico, company Atmocean with the design of a buoy — shown here in a miniature prototype — that powers...
Carnegie Mellon University researchers have developed methods to detect the body pose, including facial expressions and hand positions, of multiple individuals. This enables computers to not only identify parts of the body, but to understand how they are moving...

Some problems are so challenging to solve that even the most advanced computers need weeks, not seconds, to process them.
Now a team of researchers at Georgia Institute...

Researchers at the University of Texas at Dallas have developed a wearable diagnostic biosensor that can detect three interconnected, diabetes-related compounds -- cortisol, glucose and interleukin-6 -- in perspired sweat for up to a week without loss of signal...
This is a specially designed laser system and a new methodology based on gated digital holography enable LiDAR to see through obscuring elements like foliage and netting.

This scaled-up test bed of NEWT's direct solar desalination technology uses carbon black nanoparticles that convert as much as 80 percent of sunlight energy into heat. Results from an earlier prototype showed the technology could produce as much as...
