Selectivity obstacle_avoidance research based on relative speed

By using auxiliary triangle method,analytic result for the relative speed on four quadrants of the sphere and the computer program were brought out,then 3D curved faces were plotted to illustrate the speed distribution.

Based on the experimental data processed by the MATLAB language, the relative speed distribution curve and vectorgraph are plotted.

A car-following model with stochastically considering the relative velocity in a traffic flow;

The essential view is that the relative velocity of the burning gas directs at the rocket after the burning gas has ejected, rather than the rocket before the burning gas has ejected.

Using the documentary datum and comparative method, the author studies some technology factors of Chinese-foreign long jumpers at the absolute speed, run-up speed, rate of the speed usage, take-off ability, etc, and analyses the existing diversity, based of these, the author makes some proposal for solving questions and increasing achievement.

A query algorithm with a high absolute speed costing low I/O based on set theory is given, and a query algorithm of high response speed based on parallel process is presented.

The paper expounds briefly the absolute speed of ru n -up rhythm etc ,and attempts to improve sportsmen s long jump marks.

This paper discusses how the dynamic points and the dynamic reference system are selscted in composite movement and how the relative motion paths influence the computational points absolute velocity and absolute acceleration.

It was found that apart from his absolute velocity obviously lower than his opponents’, Huang Geng s velocity of the last 10m run up was also lower because of the influence of the absolute velocity.
