In the light of the actual situation of a certain trade center large parking lot, optimized parking design model of the parking lot is built with such data as length, width and minimum turning radius of large buses and cars, the optimized results of the optimum parking composition and arranging angles of vehicles in the parking lot are obtained based on genetic algorithm.

First,minimum turning radius of hypersonic vehicle was calculated.

Research on Method to Confirm Minimum Radius of Circular Curve of Mountain Expressway;

According to the speed and overload during vertical maneuver,the minimum radius, its speed as well as rapid rotating speed are calculated and analyzed for upward level flight, downward inverted flight and vertical ma-neuver.

This paper considers the minimum radius problem of ball-coverings with the cardinality m(≥n+1) in n by the neural network method.

Z-averace radius of gyration for the A_f-A_g type polycondensation involving initiation mechanism;

The correlation between the square end-to-end distance R~2 and the asphericity parameter A and the correlation between the square radius of gyration S~2 and A were computed for chain lengths from 10 to 23.

By analysised the different density of pendulum hammers,to same geometry size(same radius of gyration),there are two same period points which independent with hammer′s mass when the weight slip along pendulum staff.
