A parallel algorithm of non-linear high order boundary condition problem is discussed, and super-cavitation hydrofoil with finite span near free surface is given. by using non-linear initial boundary two dimension condition and three dimension lifting line theories, the numeric results of a flat plate hydrofoil are better than that of Furuya.
It is useful for researcher to predict amount of general program supported by NSFC. This paper explores the history data of amount of general program supported by NSFC, builds a regression equation of general program amount, analyses regression parameters by employing variance analysis method, and obtains predicting amount domain of general program(More)
This paper provides a tree crown reconstruction method. We calculate the total lighted area a leaf receives in a day and analyze the best included angle between a pair of leaves when their mutual overlap is considered. By using discrete summation and equilibrium condition of forces we conclude that when leaf angle is consistent with light angle, the(More)
