However, among the active subspaces, some of them do not contain any query results at all, those are called false active subspaces.

The Interference Analysis in Six DOF Parallel Robot′s Workspace Calculation;

The method of calculating cutting tool workspace is given.

The volume of workspace of parallel Numerical Control Machine Tool is regarded as one of indices to evaluate cutting properties of machine tool, and the calculating formula for the volume of the workspace is given, The influence both of structural and kinematic parameters on the workspace volume is analysed

In the teaching of science, teachers should pay attention to fostering students abilities and qualities of innovational thinking by widening the students thinking space, exploiting the students activity space and providing the students with chances of acting.

It has great practical significance to the research of how can through designer\'s endeavor providing more outdoors activity space with high-quality, rich vigor and secure to the child.

At the same time,China\'s space activities and space policies also affected the space activities and space legislation of Pacific Rim.

Therefore, a modified TM5 algorithm is proposed in this paper, which includes fast computation of spatial activity of macroblocks using DCT coefficients and a new scheme to adjust the fullness of virtual buffer.
