Abstract: When a missile runs under the complex situation such as high dynamic flying, receiver signal being blocked and so on, the GNSS receiver sometimes gets less than four satellites. For the loosely coupled system, the navigation accuracy will decrease over time. In this paper ,tightly coupled integrated navigation system which is based on pseudo range and pseudo range rate dynamically adjusts the dimension of the system according to the number of visible satellites, in order to achieve seamlessly navigation; a multiple step optimum precision factor satellite selection algorithm is proposed, an error compensation method which is based on the state transition is designed and implemented. Experiments show that when the number of visible satellites changes, tightly coupled system can seamlessly switch, when more than four satellites are received, the multiple step optimum precision factor selection algorithm can provide a combination of high precision satellites, by applying the error compensation method to calibrating the system, high-precision navigation can be achieved.

Abstract: RFID middleware for massive data focused on the performance of server-side processing to bring pressure on the issue, a new for mobile devices can be flexibly configured RFID middleware (SMM). SMM can be used for mobile devices, has a better platform independence , can be deployed with multiple operating systems ; abstract objects by device , user via the user interface (UI) and a standard Web interface to control and manage a variety of mobile devices . Meanwhile, SMM also provides data synchronization. Experimental results show that, SMM has low energy consumption; high efficiency advantages can effectively reduce server stress and improve system performance.

Abstract: The paper analyses the present situation and characteristics of job hunting and recruitment information sharing in China, takes a technical scheme of distributed data sharing based on mobile Internet and web service, combined with the actual situation of data source of job hunting and recruitment in China, designs and develops middleware of the application service. The scheme uses the mobile phone as the terminal, to publish and browse talent supply and demand data, to effectively solve the problem of distributed data sharing, and the use of google android integrated development environment-Android Studio, designs the information sharing platform of the job hunting and recruitment based on android system.

Abstract: Most quantum error-correcting codes constructed are stabilizer codes which are potentially more efficient and significant.Under the concept of graph states theory, we focused on 7-qubit graph states characteristics of stabilizer codes, by calculating and analyzing the entanglement properties of graphical codes. For the instance of code ((7,1,3)) with 16 inequitable graphs, the figure of entanglement properties can be measured.And we analyzed 7-qubit graph characteristics of stabilizers codes and calculated the entanglement measures by iterative algorithm.

Abstract: This paper has a comprehensive analysis of the cloud logistics development momentum, in view of the commercial mode theory of Alexander Osterwalder. In combination with the three aspects of assets management such as the allocation of resources, core competitiveness and the partner network , this paper lists the commercial mode analysis of XingChenJiBian Company (STARS EXPRESS).Finally, the current problems and developing trend of cloud logistics mode under e-commerce have been sorted out.And the future of cloud logistics has been prospected in the paper based on the development of cloud logistics.

Abstract: With the Internet and the rapid development of wireless communications technology, online shopping e-commerce model has been widely accepted.At the same time, people use the desktop computer to have access to a wired network outside, and they also begin to receive information and services through the cell phones,PDA,small quick and mobile equipment.This kind of new commercial trading patterns are produced, and obtained the preliminary application.In this article,we discussed the development of Huanggang mobile business,the situation status of mobile commerce,its existed problems and future development direction through the investigation of the development situation of Huanggang mobile commerce.

Abstract: Virtual Campus is the important part of the university digitization and information construction. The prototype system is established via a case study of the City institute campus, the Dalian University of Technology. 3DMax is adopted as the scene modeling tool and Unity3D is used to be the development tool in the paper. 3D virtual campus based on Web is designed and developed. The virtual campus enables the users to navigate the 3D virtual space, to guide and browse, and to inquire conveniently about relevant campus information at full length. The system runs well and maintain expediently, which means Unity3D is an effective tool for designing and developing a virtual reality platform.

Abstract: With the rapid development of Internet technology, the management capacity of traditional relational databases becomes relatively inefficient when facing the access and processing of big data. As a kind of non-relational databases, the key-value stores, with its high scalability, provide an efficient solution to the problem. This article introduces the concept and features of Key-Value stores, and followed by the comparison with the traditional relational databases, and an example is illustrated to explain its typical application and finally the existing problems of Key-Value stores are summarized.

Abstract: In response to the Tai'an City to seize new opportunities, "building strong economic and cultural city, to create an international tourist city," the goal, to contribute to economic development in Tai'an City, combined with the current actual situation Mountain Tai tourism industry, the paper constructed Mountain Tai tourism e-commerce service platform, and to promote e-commerce operations in the country. This article fully and semi positioned Walks Walks consumer groups, unlike Ctrip, the way cattle and other typical third-party e-commerce platform, Mountain Tai tourism e-commerce service platform can be used as a third-party e-commerce platform consignment of various travel services, but also independent Tarzan become tourist attractions, the official website of Mountain Tai tourism hub, is a full range of travel e-commerce platform.

Abstract: One of the key technologies of the Web personalized service is the user’s model which can precisely describe user’s interests. Mining user’s interests by their behavior is an important method in this research field. In order to analyze and study user’s browsing documents in web personalized service, this article uses a new type of personalized participle dictionary. The experimental result shows that the method is feasible. In addition, it greatly improves the efficiency of the system.
