Using the model of the slope inter-dependence on the gray system theory,the author studies the inter-relationship between the governmental expenditure and the economic increase.

First,the algorithm regards pixel neighboring sequence in overlapping area as referential sequence and compared sequence because of the relation of center point and neighboring points,then computes grey relational degree of referential sequence and compared sequence using slope relational degree,finally finds an optimal seam line which is less differences in color and texture between the images.

Study on FCC correlation models;

The experimental correlation model of mass-transfer coefficient of absorber in AIP;

A correlation model has been developed to predict the product yields by Fs and H/C atomic ratio of cracking feedstock.

Data mining is the most important step in KDD,so this paper suggests an association model based on user’s requirement.

Fundamental to the full model and its association model are discussed.

Unlike traditional EZW, the lowest frequency subband is coded separately from other highpass subbands, the SAQ process is improved by using multi threshold, the embedded coding strategy is modified and the complex context modeling is adopted in our compression algorithm.

A new image-coding algorithm based on quadtree splitting-quantization and context modeling is presented.
