Then presents the relationship between data increment detection and data updating technology.

The result is fine, which shows that the data snooping method with the new weighting function can locate all the measurements with blunders of the framework accurately and effectively in the case that the accuracy of distance measurements are different and a few blunders coexist.

Reliability analysis and data snooping are important contents in quality control of adjustment system.

By considering the quantitative relation between the residual error and the true error,this paper focuses on the data snooping and the iterative methods of weight defining for the robust estimation which are used to detect gross error.

By controlling the diffusion of exploratory message with optimal hops in free space model, the energy consumption can be more efficient.

At first the article analyses directed diffusion routing, then poposes a way which uses nodes’ regional information to control the initial interest diffusion and the diffusion of exploratory message with optimal hops.

A Method of Getting Incremental Data Based On DB2;

In order to ensure structure of neural network to fit with continuous incremental data set, a method for dealing with incremental data is presented, which is app.

The key technology of this model-meta data and its management,the capture for incremental data—is explained.

Based on the parsing of Vehicle-Infrastructure Integration probe data collection process and basic rules,a Ⅶ probe data collection simulation methodology through the COM interface of a commercial traffic simulator,named as VISSIM,was put forward.
