Individual Chinese characters are identified mainly by their skeleton structure instead of texture or color.In this paper, an approach based on skeleton similarity for Chinese calligraphic characters retrieval is proposed.By this approach,first,the skeleton of the binarized individual characters are acquired by an improved multi-level module analysis algorithm.Second,the first round of skeleton matching based on the invariant moment-descriptor guarantees the recall rate;the second round of skeleton matching based on the comprehensive characteristic difference in the polar coordinates system guarantees the retrieval precision.Finally,different styles of the same Chinese characters are ranked and displayed according to the two rounds of matching score. Besides,the efficiency of our approach is manifested by the preliminary experiment.

This paper sets up an unascertained measure model of synthetic evaluating on the stock market's characteristics, and applies it to evaluate the present characteristics of the stock market in China. This model is supposed to be strict in theory. The measure function is meticulously constructed. According to sequence in dividing the evaluating space, the rule of the incredible recognition is introduced. The evaluating result is reasonable. It is the practical model for synthetic evaluating on the stock market. The purpose is to provide quantitative point of view on the stock market to predict. Simplex technical index measure was used would be misleading to investors, the technical indicators should be used with each other. Only a number of technical indexes are applied could comprehensively reflect the characteristics of the stock market. Only investors who have a comprehensive understanding of the stock market's characteristics will be able to make more accurate investment decisions.

XML employs a tree-structured model for representing data, and queries over XML documents are typically represented as twig patterns. At the same time, keyword search over XML documents has been well studied because of its intuitive and friendly query interface. Consequently, XQuery Full-Text emerges as a full-text extension to XQuery to query both the structure and the text content of XML documents seamlessly. This paper proposes the extended twig pattern matching problem based on the semantics of 'ftcontains' expression in XQFT and develops a novel algorithm, XConquer, for matching an extended twig pattern. Our experimental results show that XConquer offers considerable performance benefits when compared with existing approach variation for this problem.

With the development of electric power industry, operating states in power plants become more complex and the data need to be displayed increase sharply. The original ways of data display can’t meet the practical needs. This paper analyses disadvantages of display and manipulate mode in operating state visualization. Based on balloon tips in windows operating system, the paper proposes to use balloon tips in DCS (Distributed Control system) visualization in power plants. The contents needed to be displayed in DCS are divided into data point, specific equipment and alarm point. Corresponding display mode is designed for the three objects. Electronic regulations are integrated as a functional module in balloon tips. The practical results show the proposed visualization technique is quick and flexible to operate. Moreover, it displays more information on the limited screen, reduces redundant window manipulation, and improves the human-computer interface of DCS and work efficiency.

To overcome the deficiencies of single neural network such as low diagnosis precision, long training time and bad generalized ability, an integrated neural network classifier is proposed for electronic circuit fault diagnosis in the paper. The investigation shows that the proposed method has higher classification precision and reliability, and is an ideal pattern classifier. Both simulation and experiment indicate that the proposed method is quite effective and ubiquitous.

Abstract: Automatic negotiation is a key problem in the autonomous multi-agent systems (MAS). How to carry out automatic multi-issue negotiation quickly and effectively has become an important problem that we must deal with in MAS. In this paper, the well-known Bazaar negotiation model is analyzed, a new idea is proposed for solving the problem of unknown or incomplete negotiation constraint information and the fuzzy evaluation is utilized to simplify the complexity of multi-issue negotiation. The new method of multi-issue automatic negotiation is established based on fuzzy evaluation and quick evolution. The experiment indicates that this method is quick and effective.

Among the numerous EMISs (Education Management Information System), the ubiquitous problems such as the difficulties for data sharing and the limited abilities for interoperating make the information systems of different colleges and different departments isolated. Therefore,the committee of Educational Information Technology Standardization (belong to Ministry of Education of China) issued specifications, Education Management Information System Interoperability Framework, which are good solutions for those problems. In this paper, the framework structures and data exchange models as well as the message formate of EMIF are discussed. The systematic analyses for functional demands of a Zone Integration Server (ZIS), the core component of the EMIF, are made, also its functional model is given. The implementation mechanism and algorithm based on message services, message transportation, and message management for the key functions such as message processing are given, and an instance for providing message processing is presented. Finally, the structure for the data interoperation among multi-EMIS on the campus net based on EMIF is discussed.
