Road network model based on virtual node joint;

Study on road network model based on virtual node joint

A method on uncertainty knowledge representation is proposed by introducing the concept of virtual node into the Bayesian network while retrieving the land surface vegetation parameters.

A practical multi-electrode extracellular recording system based on virtual testing

The concept and the theory model of the virtual testing based on virtual reality are studied.

Considering that aerial lifting basket safety lock has high critical locking velocity and low braking distance,a virtual testing and analyzing system is developed with virtual instruments and LabVIEW software.

Research on virtual test system of automobile electric power steering;

This paper studied the sub-functional models of VR-based virtual test technology by setting up its interaction model,simulation model and test model,and finally gave an example of the approach discussed.

To realize fault diagnosis and location of the missile electrical equipment economically and effectively,a method of fault diagnosis for electrical equipment system based on virtual test technology is proposed.

To convert the uncertain branches with wide possible resistance ranges into clear branches with determined resistances,an improved approach is presented by digging and converting a few untouchable nodes into touchable nodes,and supplementing the corresponding tests.

To improve the precision of finite element analysis, considering the transition elements with varying nodes in the mesh of the isoparameter elements, this paper suggested two modified methods with the same essentiality the modified interpolated function method and introducing virtual nodes method, and realized the displac.
