The goal of the study was to determine if it was possible to reduce the cost of verifying computational models of tidal waves and currents. Statistical techniques were used to determine the least number of samples required, in a given situation, to remain statistically significant, and thereby reduce...

Multiparallel three-dimensional optical microscopy is a method of forming an approximate three-dimensional image of a microscope sample as a collection of images from different depths through the sample. The imaging apparatus includes a single microscope plus an assembly of beam splitters and...

For the Space Interferometry Mission (SIM) Spectrum Calibration Development Unit (SCDU) testbed, wideband white light is used to simulate starlight. The white light source mount requires extremely stable pointing accuracy ( lights were coupled to a photonic crystal fiber (PCF).

A theoretical analysis has revealed that tapered optical waveguides could be useful as white-light whispering-gallerymode (WGM) optical resonators. The compactness and the fixed-narrow-frequency- band nature of the resonances of prior microdisk and microsphere WGM resonators are advantageous in...

As another decade comes to a rapid close, it seems like just yesterday that the main topic of discussion was how to prepare for the impending Y2K disaster that was supposed to throw computer networks into chaos and create massive disruptions in our lives. Though most level-headed citizens did not buy into the Y2K hype, many...

One may not normally associate Santa Claus with cutting-edge science and technology, but a story in our recent Tech Briefs INSIDER newsletter shows that notion is outdated. The story, based on research by North Carolina State University professor Dr. Larry Silverberg, paints a picture of St. Nick as a technical guru....

Have a son or daughter fascinated by space travel? NASA has invited more than 350 student rocketeers from middle schools, high schools, colleges, and universities to take part in its 2009-2010 Student Launch Projects. The contest is designed to inspire students to channel their interests in science,...
