Due to limitations imposed by transistor physics as device geometries continue to get finer and finer, the time when each new generation of processors was clocked faster than its predecessors is largely over. Nevertheless, as individual processor cores get smaller, chip manufacturers have turned instead to...

Concept design plays a central role in project success for space missions, as the product of concept design effectively locks in the majority of system lifecycle cost. It involves a concurrent investigation of requirements and multiple mission characteristics...

Model-based diagnosis deals with the problem of diagnosing faults in systems using a model of the system for guidance. This problem is complicated by the presence of hybrid dynamics in the system (continuous evolution of the system interspersed with discrete events like commands to...

NASA Langley Research Center researchers have developed a wireless, low-profile sensor that uses a magnetic field response measurement acquisition system to provide power to the sensor and to acquire physical property measurements from it. Unique to...

Innovators at NASA's Glenn Research Center have developed a number of materials and methods to optimize the performance of nanomaterials by making them tougher, more resistant, and easier to process. Glenn's scientists are generating critical improvements at all stages of...

Innovators at NASA's Glenn Research Center have developed a method for fabricating a fiber-reinforced diamond composite coating on the surfaces of sliding thrust bearings at low and cryogenic temperatures. The...

Material damping is important in the design of structures as it limits vibration amplitudes, increases fatigue life, and affects impact resistance. This is particularly true for composite materials, which are currently used extensively in applications that experience frequent dynamic loading....

NASA Langley researchers, in work spanning more than a decade, have developed a portfolio of technologies for low-temperature gas catalysis. Originally developed to support space-based CO2 lasers, the technology has evolved into an array of...
