In a multinational collaboration, researchers have developed a new method to produce unique reflecting patterns that can be applied on valuable objects. As these patterns can't be cloned or copied, ...

Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.

WASHINGTON--(BUSINESS WIRE)--Using pseudo-random speckle patterns is an efficient way to image targets, but most approaches require bulky, expensive, complex and slow machinery. To apply this ...

Physicists show how patterns can emerge from chaos in turbulent fluids. The turbulent motion of a tumbling river or the outflow from a jet engine is chaotic: that is, it contains no obvious pattern.

Journal of Applied Probability, Vol. 44, No. 1 (Mar., 2007), pp. 71-81 (11 pages) In this paper we study two distributions, namely the distribution of the waiting times until given numbers of ...

If you wanted to create a VGA card, you might think about using an FPGA. But there are simpler ways to generate patterns, including an old-fashioned EPROM, as [DrMattRegan] points out in a recent ...
