Abstract: As a kind of cloud computing infrastructure, Hadoop has attracted more attention from a group of corporations and has been widely used. The framework and character of Hadoop were detailed introduced and analyzed as well as the application opportunities of Hadoop in the field of communication in the future were prospected in this paper. An application based on Hadoop was designed and experiment result demonstrates the efficiency of Hadoop on dealing with big dataset.

Abstract: Basing on the introduction in the knowledge management and E-commerce concept and main theory, this paper discusses the relationship between knowledge management and E-commerce, put forward E-commerce to build the foundation o f knowledge, information flow and organization structure for knowledge management and the thesis that knowledge management constructs the sustainable competitive advantage for E-commerce. It also compares and analyzes the knowledge management and E-commerce popular model, Proposes the individual-centered organization, knowledge and business three dimensional model and the knowledge and business system model of business process which is based on the former.

Abstract: With the development of Internet scale, diversifications of applications and the network virtualization, novel applications emerge, such as search services, stream, social networks, cloud services, e-commerce, big data services and so on. Current Internet cannot afford the diversifying services any more. The network architecture should be improved or a clean slate architecture design is desired. Novel designs of future Internet become a hot topic. IPv6 is the improvement version of IPv4, which solves the address issue of the current Internet, but issues of routing scalability, security, mobility and Quality of Service are still remain. There are two ways to future Internet, improving ones and clean slate designs. The former is based on the current Internet and the latter is novel design without the limitation of the current network architecture. In this paper, we introduce related work of future Internet and summarize the locator/ID separation mechanism, SDN, OpenFlow, NDN and so on. At final, we conclude the paper.

Abstract: Beijing colleges and universities are capable of sharing teaching resources via network. However, most of them develop these resources for self-use and independently from each other. To solve this problem, the article discusses the cloud-based sharing modes of teaching resources, which integrates scattered quality resources for unified management by means of distributed storage systems and virtualization technology.

Abstract: With the rising user number of mobile smart terminal and the rapid development of Internet in our country, the demand of resources sharing between mobile terminal and the Internet becomes more and more urgent. However, the mobile banking based on mobile smart terminal is facing increasingly serious security threatens. On the basis of a comprehensive analysis of the development and present situation of mobile banking, this paper describes the related security mechanism and potential security threatens of mobile banking. Furthermore, information security technology and development trend of mobile banking are comparised and summarized in this paper, and the security assessment demand for mobile banking is proposed.

Abstract: Information recommendation systems is the one of the most effective tools to solve the problem of information overload. In this paper, we design SIRSCA, a semantic-driven information recommendation system under cloud architecture. SIRSCA mainly includes four modules: semantics representation of foundation data and user preference informations; indexing mechanism of massive semantic informations under cloud architecture; recommendation approaches based on semantic computation theory; and technologies of dynamic migration under cloud architecture.

Abstract: Virtual reality (VR) is a computer-simulated environment that can simulate physical presence in places in the real world or imagined worlds. It is new comprehensive information technology which enables users to "access" to the computer-simulated environment through the use of standard input devices and realize the direct interaction between users and the simulated environment. With a case study by using the theory of visual reality technology, this thesis analysises the application types and application methods of visual reality technology as well as the existing problems and solutions during the application process of visual reality technology.

Abstract: In the basis of the integration of traditional and network teaching, a network teaching system based on webquest and mindmap was established. Around webquest and mindmap, the main modules of the system had been designed and a new inquiry teaching model had been established, in which the teacher-leading and student-centered idea was introduced and intellectual analysis feedback circle was designed. By inputting teaching tasks, teaching situation and teaching resources, and by means of teacher's just-in-time guidance and student's thinking and inquiry, the system could output the final complete mind maps and inquiry conclusions. The system was applied to the "principles of computer network" course and empirical research was carried out in the experimental class. The experimental results show that, the network teaching system can stimulate student's learning interest, and improve student's comprehensive qualities and innovation ability.

Abstract: With the rapid development of modern information technology, some high technologies (such as the multimedia technology, the communication technology, the network information technology and so on) have been widely applied to various fields of education. Not only has the impacts for ideas and concepts of the traditional education and changes the teaching content, means, methods and forms of organization, but it also brings an extensive and profound impact for the role of teachers. The intensive study and exploration of these issues and impacts and providing the corresponding countermeasures will undoubtedly provide the important idea and reference value for the school to achieve the modernization of education.

Abstract: Nowadays the concept of Big data has become a hot issue in IT technical development. It combines frontier information techniques with scientific research method, which is also a new research direction. Power big data is an advanced application of that concept, technology and method in electric industry, involving many aspects such as electric production, enterprise operation and management. This paper briefly analyzes the character, research object and method of power big data, discusses some existential questions in research work, finally introduces application prospect of big data technology in the field of power information.
