Abstract: AIDL is a android platform to describe the inter process communication interface description language, can simplify the process of data exchange between the format and data code.Research on AIDL communication mechanism has an important significance to the realization of the Android platform interprocess communication. This paper analyzed the AIDL model and the communication mechanism and gives examples to discuss.

Abstract: First of all, three current server push modes are elaborated in this paper, including ​​a detailed analysis and comparison. Due to a single server push mode is used by the current push frame, most application requirements can not be meet. Push techniques based on analytic hierarchy process is proposed in this paper, which selects optimal push mode in different situations by theory of operations research. This method not only improves server performance but also reduces server load. Finally, experimental results show that the proposed method is superior to other single mode.

Abstract: With the development and maturity of digital libirary, the Internet has become more and more intelligent, humane and social. It began gradually infiltrated into every aspect of people's lives, influence and change people's way of life. digital libirary era as representative products -- information management has been the suddenness of a thunderbolt swept the interaction information user global information managementing platforms began showing explosive growth trend however, and people are facing information explosion but the core concept of wisdom barren embarrassing situation.

Abstract: The rapid development of big data will greatly change the government’s management mode. Each country in the world has issued various policies to deal with the development of big data, and our government also attaches great importance to the industry of big data. The e-government model based on big data proposed in the paper raises new ideas for the innovation of e-government affairs.

Abstract: Recent years have observed the frequent occurrences of grave negative events. Along with the application and evolvement of Internet and new media, enthusiasms in distribution and discussing public opinion events have heightened. Internet public opinion research has thus become one of the research priorities of scholars in recent years. Internet public opinion research places heavy premium upon the emergence, evolvement, influencing factors and other aspects of public opinion. With rapid development and deepen evolution of internet public opinion in the internet, a variety of new methods occur on network. As the internet public opinion possesses the features of various topic, complex content and large amount data, the paper constructs an internet public opinion recognition and tracking based on web mining. Then the framework of the internet public opinion recognition and tracking system is presented. At last, it puts forward the whole workflow of the system to process the internet public opinion.

Abstract: Cloud storage is an active research domain currently, and how to secure the reliability of data is an important research issue. For the moment, most systems apply the static data replication strategy, which causes a serious waste of storage resources. Considering the user requirements and the factors influenced on data reliability, i.e., the node reliability and Relevant Failure Degree, Data Replication Strategy based on Relevant Failure is provided in this paper. According to the results of the experiments, our strategy reduces the number of data replicas and meets the user requirement of reliability at the same time. Besides, the strategy has a better performance on increasing the utilization of storage resources.

Abstract: In the practical application of developmental internet, often synchronizing Oracle database tables, the establishment of a reliable remote database synchronization scheme is necessary. The paper uses the EXP/IMP logical backup tool of oracle, tuning of EXP/IMP, and combined with shell command, to implement a remote database synchronization scheme. In addition, this program implements the timing of the Oracle database synchronization.

Abstract: Analysis of user behavior management control has important significance for network users. This paper uses the clustering algorithm to cluster the user behavior for clicking certain software or Website in different times, through the time context of user behavior to analyze user behavior rules. Additionally, this paper analyzes the clustering result in detail, then, divides user behavior into different types. Finally, according to the clustering result, more targeted pages and applications are recommended to the network users to create huge business value.

Abstract: We focus the solution space of a most fundamental problem - Minimum Vertex-Cover problem - in theoretical computer science. After some rigorous analysis, we provide the formation mechanism of minimum vertex-cover solutions on the tree and give the organization of these solutions on arbitrary lattice structure. By the results, we can easily calculate the solution numbers on these structures and have better understanding of the hardness of Minimum Vertex-Cover problem. The proposed study and algorithm can make a new way on detecting the essential difficulty of NP-complete problems and designing efficient algorithms on solving them.

Abstract: Changes in the development of computing technology and calculation model of a profound impact on the development of human society, the popularity of networks and portable devices today and in the future, desktop computing mode has not been able to adapt to the changes in the development of the computer man-machine relationship changes and user computer method. Pervasive computing is in this context is proposed. The new model emphasizes the computer into people's daily life and working environment, to form a "at any time, everywhere and invisible" computing environment. In such a computing environment, user can calculate the services and information resources through the handheld, wearable devices used or other conventional, unconventional computing devices without obstacles. The innovation from the desktop computing to ubiquitous computing can be seen, human-computer interaction is an important index for pervasive computing.
