By comparison with the results of ideal Henon sequence mixed with noise,the improved Farmer algorithm is able to increase the precision of noise attenuation and reduce the absolute error between itself and ideal Henon sequ.

According to original laser measure error and error analysis transfer expressions,calculations about absolute errors and relative errors of the measuring deformation of wing were performed.

It may measure the frequency and phase of the signal which begin from 10 Hz to 20 kHz,absolute error isn′t more than 1°.

Using this new model, the paper compares the different deadweight costs of awarding risk-averse with stock options and restricted stock compensations , and finds that managers prefer restricted stocks more than e.

The proposed fast selection algorithm for intra prediction uses sum of absolute difference(SAD) to filter out some less probable modes,reducing the complexity of intra prediction and improving the speed of the mode decision.

2, a new method by improving the calculation procedure of SAD in macro block is proposed in order to reduce time consuming of motion estimation with minimal loss in video bitrates.
