A new lab at the National Institute of Standards and Technology (NIST) is dedicated to improving the quality of light that light-emitting diodes (LEDs) produce. NIST vision scientists Wendy Davis and Yoshi Ohno and a team of physicists created the NIST Spectrally Tunable Lighting Facility (STLF).

A report discusses the Lift and Nozzle Change Effects on Tail Shock (LaNCETS) test to investigate the effects of lift distribution and nozzle-area ratio changes on tail shock strength of an F-15 aircraft. Specific research objectives are to obtain in-flight shock strength for multiple...

Spacecraft landing on small bodies pass through regions where conventional gravitation formulations using exterior spherical harmonics are inaccurate. An investigation shows that a formulation using interior solid spherical harmonics might be satisfactory. Interior spherical...

A document discusses a method for producing nanophase iron lunar dust composite simulant by heating a mixture of carbon black and current lunar simulant types (mixed oxide including iron oxide) at a high temperature to reduce ionic iron into elemental iron. The product is a...

National Semiconductor (Santa Clara, CA) has introduced the WEBENCH® LED Architect, which enables novice and expert designers to perform real-time comparisons and optimize complex lighting systems for performance, size, and cost. To start a design, the designer enters desired light output (lumens) and adjusts the design with...
