The article has conducted an in-depth research to aim at the existent problems of the FDBSCAN algorithm,proposed a method that choice representative objects from core points in the core fields,resolves the problem of loss points t.

The second stage was to make sure the real core point using the identification mask.

Core point,as an essential feature of fingerprint,plays an important role in fingerprint matching/classification,where the core point region is distinguished from non-core point region by the machine learning method,and their ridge orientation distributions can be used to form training data.

Hardware Design and Improvement of Synchronization Core Node in OBS Network;

Hardware Design and Implementation of Core Node in OBS Network;

The FPGA Design for the Edge Node and Core Node in OBS and LOBS Network;

Finally,based on the core node set and the feature of "local optimal",we get the members of communities by using a breath-first algorithm.

Review of Brand Relationship Research:Views, Themes and Core Issues

And depending on the Five Rings Chart of the Organization Competence, it introduces the setup of key factors system, the decision of core operation points and the quantification of check system model.
