Improvement of negative selection algorithm based on hamming distance;

Calculating Hamming distance of DNA codes with linear constructions;

The rock mass blastability was divided into seven grades to analyze the blastability classification indexes of seven types of rock mass of an iron mine,in which the weighted Hamming distance was applied to determine the blastability grades of the rock masses.

Dynamic crossover and mutation operators which are based on Haiming Distance are brought forward in this paper to maintain generation s diversity.

The concept of fuzziness,the absolute Haiming distance ,and the two-way evaluation standard are adopted to express the surplus and lack of some ions in groundwater in this region .

A binary image watermark authentication method based on Hamming Code

Hamming code is of a forward error correction coding ability,the data error correction is carried out at the receiver,without the request of re-sending,and the original data can be correctly obtained from the wrong data.

A Hamming code error-correcting system based on FPGA is designed for this purpose,the principle of its implementation is elaborated on from two sides,one is the sending side which completes Hamming coding,the other is the receiving side completes correcting and data gaining from the Hamming code,th.
