Remote sensing opens a new method for obtaining forest canopy density. The forest resource field inventory data and simultaneous LANDSAT TM data were used to discover the model of estimating forest canopy density based on remote sensing here in Shimian county, Sichuan province, P.R.of China. A lot of derivative data were created from LANDSAT TM data. 1204 forest sub-compartments with inner homogeneity...
Roughness of concrete pavement is partly due to cracks, potholes, road repairs and so on, therefore, pavement roughness is correlated to distress rate. However, the correlation is not clear, and has not been reflected in existing pavement evaluation models. Firstly, linear and nonlinear regression are used to analyze the relationships between international roughness index and pavement distress rate...

Taking 22 Chinese Taibei men volleyball players as the subjects, we have tested 16 physical quality indexes related to the players' leaping abilities. A “0–1 program” is used to filter the tested figures according to such indexes and the selected ones will be examined by multiple regression analysis to establish the regression model. It has been tested that this model is of statistical significance...
