Based on this model,feature based fixture automotive variant design was realized based on geometry reasoning.

This paper introduces a method which uses geometry reasoning & degrees of freedom calculating based on constraint driven to solve the problem of checking over constraint & under constraint.

In order to increase the efficiency of traditional construction process planning,this paper presents an approach to automatic construction planning based on artificial intelligent and geometric reasoning.

In this paper, a geometric reasoning algorithm for grasping planning of intelligent robot is introduced.

The artificial intelligence techniques in-cluded in the approach, such as constraint manipulation and geometric reasoning, can deduce and predicateimage models when only the partial 3-D information of object are known.

A geometric method of qualitative analysis and stability analysis of plane dynamic system;

Study of geometric method for angle-of-arrival distribution according to phase fluctuation;

A geometric method was discussed for detendning the orbit of satellites in double satellites position ing system.

It deals with the fundamental concepts, variational principles, equations of motion, special problems, integration methods, algebraic structure, and the geometrical methods of nonholonomic mechanics.

This paper gives a general formula for the acceleration of instantaneous cen-tre of (?)gid body s rotation in the planar motion and the theorem of angular momentumof rigid body was worked out,with the geometrical method.
