This At present, bigdata has risen to the national strategy. bigdata is fully integrated into the military field, becoming the driving force of military scientific research, the core element of construction management, and an important resource for war success. This paper mainly expounds the basic connotation of bigdata technology and military bigdata, and analyzes the application of military bigdata in equipment quality information management, and proposes information collection, storage, analysis, processing, exchange and feedback on equipment quality information management. The countermeasures provide methods and basis for military bigdata in equipment information management.
Quantitative research has been extensively applied in sociology. The traditional way of using data statistical computing tools of R, SPSS and Stata on the stand-alone machine can't deal with the challenges of big ...

Recommender system algorithms are widely used in e-commerce to provide personalized and more accurate recommendations to online users and enhance the sales and user stickiness of e-commerce. This paper discusses several recommendation algorithms and the challenge of tradition recommender system in bigdata situation, and then proposes a framework of distributed and scalable recommender system based on Hadoop. The recommender system based on Hadoop, combining the advantage of computational ability and scalability of MapReduce and hybrid recommendation algorithms, brings a solution to information overload problem in big e-commerce.

Mobile cloudcomputing (MCC) integrates the smart phones with the cloudcomputing technologies, which has resolved the problems of limited storage capacity, battery lifetime and processing capability of the mobile phones. In current mobile applications, mobile devices often require data uploading and downloading tasks with the cloud server. However, connecting mobile devices with the remote cloud servers, suffers from the huge transmission energy consumption especially when using 3G/4G/LTE connections. In this paper, we present a cloudlet based energy-saved data transfer model (EDTM), which focuses on reducing the power consumption of mobile devices while using MCC. And the data upload and download operation process which support users mobility scenarios are given. We hope the proposed data transfer model provides future mobile cloudlet computing research with a guideline and theoretical supports.

Cultural hegemony is an authority with which the subject of cultural hegemony leads group members to form specific values, ideals and faiths, etc. by means of cultural leadership. According to Huang Cui's empirical research methodology of quantification of policy documents and through analysis of the quantity of releases, social network clustering and co-word analysis of 10986 culture-related policies published, this paper reaches a conclusion that the power of the subject of cultural hegemony, the power structure of the subject of cultural hegemony, and the main culture and information dissemination of cultural hegemony are the key influential factors on cultural hegemony construction.

With the popularity of private cloud, how to protect the private cloud network security has become the focus of more and more enterprises. The enterprise information security system needs to integrate the information security construction into the infrastructure construction. Enterprise private cloud network security situation is a systematic, overall situation management engineering problems, and any private cloud vulnerabilities may lead to paralysis of the entire network. This paper takes the basic network security situation, bigdata security, private cloud network security situation as the entry point, analyzes the relevant evaluation indexes, and establishes the evaluation system model and other key technologies, elaborates on the private cloud network security situation in enterprises.

With the rapid development of streaming media and cloud technology, new opportunities have been brought to the progress of network distance education. In order to solve the bottleneck problem of data processing, cloudcomputing architecture and mode are adopted to ensure the data processing ability of the platform. The design of distance learning platform based on cloud technology is given, and CDN (Content Delivery Network) and flash P2P (peer to peer) is used in the streaming media service system. The stability of data and the user experience effect is improved.
