We proposed a new dynamical description for the arbitrary neighborhood rule cellular automata, and a new kind of reproduction pattern, copy-reproduction.

This paper introduces a practical measuring system, which, under the control of micro-computer, can measure the surface roughness of casual position in special long deep-bore (includingblind bore).

Implementation of parallel CRC approach of arbitrary bit length and encoder and decoder;

A novel calibration method to determine all the primitive parameters of the stereo visual sensor with free-position planar pattern is proposed.
