In order to improve the design method of non- symmetry T-network low pass filer in voltage source inverter, 3-D state trajectory visualization method incorporating time domain simulation was proposed.

Research on taxi trajectory prediction based on conflict detection in surface management system;

Considering Bit-Rock Interaction, anisotropy of bit-cutting and forces applied on the bit etc, a reentry horizontal well trajectory prediction model suited for sliding using BHA with bent housing was presented.

In order to satisfy the online trajectory prediction of multi-machine system,polymerization technology of trajectories was used to reduce the computing burden.

The track forecast of intersectant objects by general Hough transform;

In consideration of maneuverable ability of missile,a track forecast guidance law is presented to meet the requirement of falling angle and to hit targets precisely based on traditional proportional guidance law.

With the advancement of mobile computing technology and the widespread use of GPS-enabled mobile devices,the location-based services have received more and more attentions,and the path prediction of moving objects is one of the most important issues.

The simulation confirms that the algorithm proposed in this paper has higher accuracy than other path prediction method.
