Abstract: The research of College English mobile learning platform based on mobile phone help to develop and improve mobile learning theory and provide a solid theoretical foundation for future generations; on the other hand, it also help to achieve the learning style with student-centered, Individualization and self-control the learning process to stimulate College students 'interest in College English learning and improve College students' English ability.

Abstract: To avoid the cost due to security problems, the repair and defense the threat of information, this paper build information system CAACM the tree structure model, through the study of the characteristics of attribute date classification, and then reconstruct the formula defined data characteristics depend on the degree of classification properties can be achieved, propose a classification attribute data for feature selection algorithm. Simulation result demonstrates the effectiveness of the algorithm.

Abstract: In the mobile Internet era, in order to learn whenever and wherever possible, we design a mobile learning system based on Android platform. With the key technologies introduced, we design the overall architecture, structure layer and system flow of the mobile learning system, and further design some function modules.

Abstract: Nowadays, cloud computing is widely concerned, it is a new generation of information resource sharing and application mode. It provides IT resource services in way of virtualization and resource pool, which is the extension and development of network distributed computation, and greatly improves the sharing and utilization of information resources. This paper describes the significance of constructing current maritime navigation information resources of cloud platform, presents the research methods, and designs the platform construction structure. By the cloud platform, we can realize the integration of existing maritime information resources, the analysis of business process, the cleaning, selection and aggregation of business data, and finally achieve the unified management of navigation application system and business data of maritime Departments.

Abstract: SDN is the current hot research topic in the network area. It becomes high-profile because of being considered as the direction of next-generation network. Service deployment is the core content of northbound interface and the focus for researchers in SDN. So far, there are still rare successful SDN application cases, the relevant researches on service deployment are even fewer. Based on the concept of service deployment, we bring up a service deployment framework in SDN, build a service deployment model, and then study the problem of price calculation during the process of service deployment and present some corresponding optimization algorithms.

Abstract: Network centric warfare is the main development trend of informatization warfare in the future, while the present of network centric warfare has raised higher requirements for the future equipment support. In this paper, the new thoughts and structure of network centric warfare are put forward by comparing network centric warfare with traditional warfare. And the command flow of equipment support is analyzed specifically combined with the instantiation. The establishment of the equipment support model can promote the development of network centric warfare and has guiding significance and applied value for the establishment of the future equipment support model.

Abstract: Now, as the security threats for the Android phone increasing, the security problem about the smart mobile-phone has become a focus of the topic. In this paper, we take the security problems on Android operating system as the study object .Our contribution in this paper is two-fold. First, SQLite database is the mainly way for data storage on Android, but no security mechanism was provided in SQLite, we implement data encryption technique refer to the common database security mechanism. Second, in order to solve the security threats existing in the traditional phone, we also give a design and implementation of multi-function mobile phone firewall.

Abstract: In order to adapt to the demand of integration and sharing about electrical power school and to break the limitation of "Islands of information", it is necessary to develop a loosely coupled information system. This paper introduces the system application demand of electrical power school, and designs the functions of the system and scientific object-oriented data model. A concept of operating mode information system is designed based on cloud computing. Object-oriented programming language C# is used to develop the prototype of the system. The result of application is showed in various UI. This paper provides a valuable reference for the information technology future about electrical power school

Abstract: The ability of acquiring and processing information in manufacturing influences agile of manufacturing system. According to the idea that networked field information processing is realized based on intelligent nodes of field-bus technology, distributed intelligent field information processing flow is researched to synthesize multiple functions such as information gathering, information processing, warning system and field control. The method of information represented and collected was put forward. The multilayer data fusion model of distributed intelligent field information processing is built. Then the distributed LonWorks fieldbus monitoring model (DLFMM) based on LonWorks fieldbus technology is established. A monitoring system of a rail vehicle automatic door factory is shown as an example to illustrate design strategy of monitoring system based on DLFMM. This monitoring system shows that the model of distributed intelligent field information processing, DLFMM and the extraction and representation of information flow discussed in this paper are reasonable and applicable.

Abstract: This paper presents an approach for modeling and implementing e-textbook (electronic textbook) resource organization and storage using a content structure model. The model is divided into three layers, namely atomic component layer, composite component layer and component pool layer, and provides the means for the reclassification and package of e-textbook resource. A formal definition is proposed for the model, and a storage algorithm is analyzed. The results show that the approach has the following characteristics, such as low resource maintenance cost, simple and efficient access, large and uniform directory capacity, and easily expanded storage space.
