In this paper, serial algorithms associated with editing Delaunay Triangulation oriented huge terrain are presented which based on the spatial index of quad tree, including the algorithm of adding constrained point, the algorithm of adding constrained line and the algorithm of fast searching the group of common vertex triangulation.

The constrained texture mapping algorithm is an approach of texture mapping,and it can maintain the alignment of the corresponding features in the texture mapping process by the predefined constrained points.

Then,a new method to compress the non-topology polygon data based on constraint points is put forward.

Research on ship ant rolling control with robust pole constraint;

Firstly,based on the T-S fuzzy model of ASV re-entry attitude dynamic system,considering external disturbance and system uncertainties,the stabilization problem of angular rates and attitude angles is studied,then combining with pole constraints,an existence condition for H_∞fuzzy guaranteed cost control law with pole constraints is derived.

The uncertain attitude dynamic system descriptor during ASV’s (aerospace vehicle’s) re-entry phase based on T-S fuzzy model with parameter perturbation is considered firstly, then, the stabilization problems of attitude angles and angular velocity errors are researched, and combined with disk pole constraints, a condition for the existence of fuzzy guaranteed c.

Influence of glass and joint constraint on loading capacity of monolayer cable net for point supported glass buildings;

In the whole matching process,the corner constraint and the edge constraint were proposed to guarantee the matching speed.

"PATRAN" is used to create a canopy FEM for an aircraft using MPC to simulate the flexible attachment between plexiglass and frame.
