Abstract: With the development of information technology, the network information resource grows rapidly. The information collection, processing, storage, retrieval and utilization of the construction of Library Digital Resource have become the important issues of library management. It is also the new hot topic of Library digital. Firstly, this article analyzes the using of digital library resources in developed countries. According to the survey data, it analyzes the utilization of Chinese digital library resources and digs out the main problem. It uses SWOT method to analyze the association of external environmental and internal functional factors of the entire construction of digital library resources. Then it puts forward some scientific suggestions of the development of digital library which provides theoretical basics and technical supports for the construction of the digital library.

Abstract: This paper analyzed on real-time database system, and applied the cloud manufacturing technology and distributed system technology to the database system model. Through the analysis on the real time database, we can got the distributed real-time data system types and data storage model, establish two kinds of memory T-mode and S-mode, database storage model and make the production of block. Finally establish the work flow of distributed real-time database system, get relevant application program. A large number of real-time data collection and administration can be realized, which can improve the real-time information data processing efficiency and system model performance. Through the establishment of model and analysis of its working process in the real-time distributed system real time database application path, it can provide guidance for the establishment of distributed real-time database system model.

Abstract: Database technology as the data management technology, has become the main mean in the extraction methods of computer information management. This paper is focus on the information extraction and puts forward an inaccurate method of statistical model structure of planning database to carry on the information extraction method. For information database technology, it can record text address and cited as an example to have information extraction method. And it establishes a conditional probability distribution of the automatic extraction model of information and data, and gives input sequence, establishes the target demand curve, at last has best segmentation of the data information, to seek out information extraction path and the algorithm formula.

Abstract: Through analysing the assembly relation between the product parts, this paper divided the product parts into function parts and the connectors. Then the simplified assembly semantic relation graph model was established in this paper. The concept of assembly connection strength was introduced to express the complexity of assembly between the parts. Using the least assembly time as the goal to determine the optimal unit division number, the assembly unit division was accomplished based on the connection strength. Finally using the spindle box of HTC2500hs as an example to check this division method, the results show that this method has applicability and effectiveness.

Abstract: Under the aims at corpus automatic collection on the process of the large-scale Lexicography corpus collection, the paper described corpus collection Technology which is based on Web. And then, the paper introduces the book information corpus tool, including how to make use of the technique of search engine and information extraction in our system.

Abstract: The study of distributed search engine based on Hadoop (referred to as DSEH) has put forward system structure of distributed web service search engine based on Map/Reduce, and made introduction to related modules. Built the whole system on Hadoop framework by Map/Reduce and analyzed the key technologies of distributed search engine.

Abstract: With the rapid development of smart grid construction, communication mode size in smart grid business relying on operators 2G/3G wireless network continues to increase. In this paper, first, with a deep study of application, communication requirement and network status in power wireless business, the security risk and defects cannot control in the existing power wireless business are noted. Secondly, wireless VPN target of power grid is innovatively put forward, to achieve the safe and efficient power wireless business hosting, intensive operation and scale development. Once again, the design of wireless VPN for power grid, security access platform, operating platform are made a further analysis and elaboration.

Abstract: Artistic treatment methods for ordinary black matrix QR code are discussed. The design and development of artistic QR code generator software are completed by using WPF technology under Visual Studio platform. The software can generate QR code dynamically based on users inputting, and provides a series of artistic treatment methods to deal with the code including setting colors, setting shape of the module, adding LOGO and rotating transform. QR code generated by the software is not only beautiful but also successfully recognized by kinds of scanning software. The software can be used to handle a variety of marketing mediums and it has high practicing values.

Abstract: Oil and gas resource as the most important part of energysource compositionits in China, its seismic exploration and development has great significance. And this requires development of new generation of high-precision digital telemetry seismograph. Shared memory, the common telecommunication mode between Linux processes becomes the preferred interaction means between applications of seismic exploration for its controlled capacity and speedy interaction rate. This article describes the stacked power station being constructed by the embedded microprocessor PPC405 and FPGA chip, as well as the transplantation of U-boot, Kernel and file system, the development of inter-process communication application on basis of shared memory, and finally the network interaction of telemetering digital seismic power station.

Abstract: The book recommendation system is mainly designed with Struts2 + Hibernate + Spring technologies in the Web design. This paper analyzes the functions of the system, introduces the systems architecture and the key technologies of system implementation, and proves the effectiveness and practicability of the system through experiment.
