Abstract At present WEB application server especially image server lacks of effective methods of anomaly diagnosis. Therefore, this paper presents the method of anomaly diagnosis based on the dendritic cells algorithm of Danger Theory. The method can achieve the purpose of monitoring system status effectively by building a multi-layer indicator system.

Abstract In heterogeneous data integration, an effective machine learning model plays an important role in schema mapping. Schema mapping machine learning model and its probability learning improvement are analyzed in this paper firstly, and then the concept of multi -analyzer model with the method of fuzzy comprehensive evaluation is put forward to improve machine learning results’ efficiency and accuracy. Comprehensive experiments on multi-analyzer model confirm... In heterogeneous data integration, an effective machine learning model plays an important role in schema mapping.

With the diversification of customer needs and the widely use of 3D CAD systems, in order to make the 3D CAD system truly become the best carrier of professional technologies and realize the accumulation and reuse of enterprise design knowledge and design process, a design knowledge management method based on 3D CAD system is presented. In this method, a Design Navigation system based on 3D CAD system is researched, which can build Design Navigations for different products with language engineers are familiar with, and make product design visualized and processed. The mechanism of knowledge classification, management and reuse is also established for Design Navigation, design model, standards manual, formula, charts, drawings, and so on. This method was applied in piston design, and was approved to be effective in design knowledge accumulation. With this method, design experiences of senior staff can be accumulated within the enterprise in forms of parameterized features, standardized design process, precise rules and verified methods. Finally, design efficiency and quality of modularized and serialized products were improved, and the accumulation of design knowledge and design process was strengthened. Read More Read Less
