An algorithm processes the pixel intensities of a digitized image to detect and locate a circular bright spot, the approximate size of which is known in advance. The algorithm is used to find images of the Sun in cameras aboard the Mars Exploration Rovers. (The images are used in estimating...

“Extreme Programming: Maestro Style” is the name of a computer-programming methodology that has evolved as a custom version of a methodology, called “extreme programming” that has been practiced in the software industry since the late 1990s. The name of this version reflects its origin in the work of the...

A method that notably includes the use of compressed representations interleaved with non-compressed (time-line) representations of a general scheduling problem has been conceived as a means of increasing, by orders of magnitude, the speeds of computations needed for scheduling complex...

Robust and reliable autonomous navigation in unstructured, off-road terrain is a critical element in making unmanned ground vehicles a reality. Existing approaches tend to rely on evaluating the traversability of terrain based on fixed parameters obtained via testing in...

Organic photovoltaics, which rely on organic molecules to capture sunlight and convert it into electricity, have come a step closer to reality thanks to discoveries by NIST researchers. The scientists have deepened their understanding of the complex organic films at the heart of the devices.

Although less publicized than alcohol, driver fatigue is a major contributor to auto accidents in the U.S. The National Highway Traffic Safety Administration (NHTSA) estimates that 56,000 sleep-related road crashes occur annually in the U.S., resulting in 40,000 injuries and 1,550 fatalities. According to the...
