Tibetan coding method and mutual conversion

This paper introduces the concepts, features and coding methods of 39 bar code, and connecting with the practices, puts forward two kinds of print technologies of 39 bar code based on C#.

In consideration of new demands of cadre file management, this paper discussed the regular of coding cadre personal records and made a conclusion that sequencer-coding method could adapt to the rapid developmen.

This paper introduces four kinds of encoding modes ba sed on XT-14 color-TV signal generator s circuits and their adjusting method.

In this paper,considering the difference of modulate area,multi coding mode is presented.

Error rate is calculated,and the error rate curve is illustrated upon different coding modes.

Recently,to meet the requirements of miniaturization,intelligence,integration of the photoelectric shaft encoders,a lot of research work are developed to reduce the sizes of photoelectric shaft encoders in many countries,especially in research on the coding modes.

Several encoding methods of partheno genetic algorithm (PGA) are given out and it is pointed out that uniform combinatorial optimum problem can use different encoding methods by different gene number of the same order and those encoding methods distinctly differ in the size of string space.

Some improvements are carried out on the encoding scheme and genetic operators of the crossover.
