Abstract: As a large number of the multimedia information emerges, the cross-media retrieval system becomes an important research focus. The cross-media retrieval system is based on the traditional content retrieval, extracting color, texture, and shape features vector of the images. A new method was carried out in this paper. Firstly, the uniform semantic representational framework was built to organize the different mode media heterogeneous characteristics. Secondly, the Ontology database representing each type of media concepts was set up. The Ontology database organizes the low level features of the multimedia objects to associate multimedia files in the semantic level. Thirdly, the cross-media retrieval algorithm based on ontology was introduced. The results of the experiment showed that this cross-media retrieval method based on the Ontology was more effective and accurate.

Abstract: Plant is not only closely related to human beings’ life, but also an integral part of raw materials in production. Protection of nature and plant resources is an increasingly urgent needs around the world. Cognition is a prerequisite for the protection of plant. But the way of plant science popularization is old, the knowledge of plant is too obscure to the general public. The system of plant science popularization based on the QR code spreads the knowledge of plant with illustrations interactively, to facilitate ordinary users to learn, understand and identify plant species. The article will detail all aspects of development of the system, allowing more scholars to understand the digitized plant science popularization under the new media.

Abstract: In order to achieve a paperless office, to improve test efficiency and save costs, we develop an online examination system. The system is designed by JSP technology and SQL Server database. Through two years of use proves that the online examination system facilitates and simplifies the test process, and makes the teacher complicated free from the examination process and has more time to study the teaching and the scientific research. The system has saved printing papers costs and office expenses. Online examination reflects the characteristics of the course Network Information Retrieval and solves the problems that paper test can not comprehensively inspects the student's ability of application.

Abstract: To implement the multi-directional test of WAMS application system, and to satisfy the requirement for the flexibility and reusability of WAMS application system, the test platform of WAMS application system is designed and built. Firstly, the basic functions, the platform components and software structure of the test platform of WAMS application system are described. Then, the realization of data model and multi-source data interface and other aspects are expounded in detail. Finally, by using the test platform developed completely, the test case aiming at the disturbance source location system based on the WAMS data is produced, and test work of the disturbance source location system based on WAMS data is finished. The test results verify the accuracy and practicability of WAMS application system. Moreover, it proves the use value of the test platform; the test platform of WAMS application system can not only reduce workload of the test work remarkably, but also enhance the standardization degree of the test program and the reusability of the test case, which plays an important role in reducing the research cost of the WAMS application system and speeding up the progress of the research.

Abstract: Internet-based multimedia network for moral teaching system already been an ordinary thing, but they all lack of teachers and students in interactive sessions, in order to effectively improve the interactivity and effectiveness of online teaching, this paper studies the online browsing courseware, online division and online various teaching resources systems, providing a good online learning platform, the use of second-generation network technology to achieve real-time communication between teachers and students and students to enhance the online teaching interaction of teaching system.

Abstract: Rapid development of information technology in education not only leads to great changes in the field of education, but also results in some security risks. How to ensure the safety of teaching resources has become a hot topic in current research in the teaching system with the cloud-terminal integrated digital classroom as scene. In the paper, importance of identity authentication mechanism is proposed by analyzing defects of cloud computing firstly, multiple identity authentication technologies are adopted for privacy protection of data. Features of four technologies, password authentication, smart card authentication, USB key authentication and biometric authentication, are analyzed in details. A set of multiple identity authentication system is designed and realized. The system is designed in Detailed system architecture is designed in the system for improving dynamic password technology and fingerprint recognition technology for ensuring data operation of legitimate users. Mobile terminals should be combined as example, and actual test can be conducted aiming at account recovery, remote data destruction and other demand after unexpected loss of smart terminal equipment. The result shows that the system can ensure accuracy and reliability of account and hardware equipment with excellent test effect.

Abstract: Based on the analyzing of digital textile picture, pattern, and feature, Digital textile computer simulation is proposed in this paper. A series of softwares are used to make the digital patterns. and some examples are showed done by software. They are created by experiments of classic patterns and parameters or combination of several softwares.The results shows that the methods of making digital textile pattern are useful and available.

Abstract: A software quality evaluation method for vehicle based on set pair theory was proposed. The evaluating index system of software quality evaluation for vehicle was constructed. The software quality evaluation models were constructed by using four-element connection number of set pair theory. Then the computer-implemented method was given, and was verified by an example. Finally, the practical application showed that the evaluation method was simple, effective and had good practicality.

Abstract: The Value Stack , Object Stack, and Context Map are important concepts in Struts2, but many books and websites have their own opinions. This paper use the “debug” tag of struts2 in JSP and the debug function of MyEclipse to research their relationship.

Abstract: During the research of cosmic rays in high energy physics, the data produced by real-time observation and simulation experiments is increased all the time. Besides, various physics detector must have description to explain their characteristics. These data become great pressure for the research center. Once LHAASO project officially begins, the data it produced will be approximately several PB. How to store and get data with high rate, along with manage files efficiently, is an important issue.The topic is designing a data management system of LHAASO project. The design will be reference for the engineering of BOOKKEEPING in order to render excellent services for LHAASO project. Its key points are designing friendly and succinct page, using Hadoop platform to distributed store and manage data files, recommending data warehouse principle to associate data source, and uniting Kettle to transform different data files.
