Show Abstract
Voronoi diagrams are essential topics of modern physics, chemistry, biology and other fields. There is a great interest in generating Voronoi diagrams for real-time applications that can be made by means of parallel analog computation. We report the observation of self-organized Voronoi diagrams as a pattern arising in a barrier gas-discharge system. It is shown experimentally that this phenomenon provides an opportunity to generate Voronoi diagrams in a parallel way for a given set of reference points on submillisecond time scale. © 2002 American Institute of Physics.

Show Abstract
The correlation between the vacuum ultraviolet (VUV) luminous efficiency and the plasma ion density has been investigated in terms of the xenon mole fraction in the neon filling gas for alternating current plasma display panels. The VUV luminous efficiency and plasma ion density are found to have strong correlation and to be saturated at xenon mole fractions greater than 7% and gas pressures of 400 Torr. © 2002 American Institute of Physics.
