E-mail is the most commonly used network application which has become an important way of network communication. The research of content-based spam filtering technology is a key problem of the Internet security field. The paper described a spam filtering which was based on the Naive Bayesian algorithm and designed a spam filtering model based on the naive(More)
In order to satisfy the fault diagnosis of transformer, here, a fully bran-new diagnosis model of transformer was being put forward, which is based on the technology of information amalgamation, and have got an ideal result through applying it to the fault diagnosis of transformers. In order to get this model, here, through using the measures of DGA method,(More)
Aiming at the inherent uncertain problems in motor fault diagnosis, in this paper we propose a new kind of motor fault diagnosis method, which utilize the parallel Bayesian network and D-S evidence theory based on multi-source information fusion technique. Firstly, the set of motor fault features is divided into multiple fault sub-spaces and each fault(More)
A more and more enterprises using Web services to accelerate its own development. At this point, how to network in an open application environment, guard the confidentiality of their data, resources are more and more concern for people, network security has become the network an integral part of the building. This paper introduces the architecture of(More)
In this paper, as the issue of Bayesian networks with missing data bring out a repair method of data. This method through a score function to score all nodes, so can obtained for all states points of the Bayesian Network. This is to say all states which belong to Bayesian networks matching degrees can finalized determine the add data's states. Experiments(More)
The problem of the synchronous drive for gantry-moving milling machines is researched in the paper. Two same linear motors are used as drive mechanisms of synchronous feed. The dynamic compensated method is adopted, effectively limiting the falling of the system's performance which is produced by the changing of the equivalent inertia. At the same time,(More)
The gantry-moving boring-milling machining tools that adapts dual linear motors drive is a high precision and fast motion system, the factors that influence the synchronous performances of the system are not only unknown bounded disturbances but also have parameters variation, unmodelled dynamic and the nonlinear uncertainty. These factors will make the(More)
