Abstract: Resources of memory are frequently used times without number for reducing cost of control system. Rewriting in memory would cause occasional hardware conflict when especial data are inputted or are calculated, thereby system faults even accidents are elicited. Origin of occasional malfunction was analysed in automatic control system, necessity of program storage separate from data storage was discussed, and the notion was put forward that resource allocation of memory should be compatible with the system function. So dead halt owing to codes cover each other could be avoided, and reliability of measurement or control system could be effectively improved.

Abstract: Recently, the amount of blogs on the Internet rises sharply. Hence, mining valuable information in blogs possesses realistic significance for improving user experience, network services, etc. This paper proposes a mining algorithm with blog authors' interests based on classification techniques, which introduces an evaluation standard of non-empty intersection. This algorithm can also improve the hit ratio of recommendation service based on blog authors' interests by means of the interest collection from expanding prediction; therefore, it can reach a higher degree of satisfaction. In addition, this paper performs experiments with the data set from Sina Blog and NetEase Blog, whose result illustrates the higher accuracy of our algorithm. Keywords: Blog mining; Interest mining; Classification algorithm; Non-empty intersection.

Abstract: In order to solve the data interaction problem of title bar between the AutoCAD and ERP system, the information processing technology of title bar for the AutoCAD/ERP integration was put forward. The overall principle of technology was analyzed, and some key technologies and methods were studied, including the technology of identifying and extracting the data, the data integration method with ERP, the design principle of the drawing number generator, the technology of filling information into title bar, etc. Based on these, the information processing software of title bar was developed by VB. It could make the information of title bar rapidly transfer between AutoCAD and ERP.

Abstract: Based on examples of the application of e-government, this paper aims to provide a theoretical study on how the Information and Communication Technology (ICT) helps to increase the innovation dynamics of the regional systems. According to the literature review, we understand the innovation dynamic of a regional system is generated from the interplay of the knowledge production between different actors such as government, university and industry. ICT can be viewed as the stimulus of facilitating the e-government to develop the innovation dynamics. Accordingly, some examples of the application of e-governments around the world will be provided for a deep understanding the link between ICT and innovation dynamics.

Abstract: To design parallel algorithm for gravity and magnetic 3D forward and inversion, we used multithreading technology. Calculation process was decomposed into two major parts: forward program and inversion program, and the amount of two-part calculation can be equally distributed to computing threads. The results show that algorithm can increase calculation efficiency, and this process is reliable and efficient.

Abstract: IPv6 has the advanced nature compared with IPv4.The IPv4/IPv6 transition is inevitable to the current network development, but it is impossible to upgrade from IPv4 to IPv6 in short time. The transition is a gradually process. In order to achieve the stable transition, we must select the most suitable strategy according the different time and the different network environment. Introduce several kinds of commonly used transition strategies, Analysis on the evolution of IPv6 and the selection of IPv4/IPv6 transition strategy from both vertical and lateral, and in the paper.

Abstract: HDFS is a distributed file system designed to access large files, which is inefficient for storing small files. For this issue, a new storage architecture based on the HDFS is designed to solve the problem of low efficiency of HDFS storing small files in this article. This paper mainly uses SequenceFile to merge small files and against to the shortcoming that SequenceFile merges small files, the paper provides the solution and designs a new system structure based on HDFS. The system mainly increases the file judgment unit to mark and identify small files, creates a local index file which is helpful to improve the retrieval efficiency of small files to record the size and offset of the small files and finally uses binary serialization to merge the small files, which makes small files be written into large files as time order.

Abstract: With the development and advancement of technology, remote sensing data of MODIS satellite become more precise, loved and applied by relevant researchers widely. This software enables remote sensing data of EOS/MODIS satellite's automated ordering and address of FTP resource's accessing, providing convenience for users. Currently, the software with stable and reliable performance, is robust, fully automated, and can provide services to all kinds of users of remote sensing data of MODIS satellite.

Abstract: Based on the method and process of manual design of the synthesis mining curve, as well as the characteristics of the data source and real-time information release, the system realizes the auto-design network platform of the synthesis mining curve based on J2EE. The system mainly uses JSP, SSH and JDBC database access technology etc.. This paper briefly describes the system framework, system function and each layer realization, such as the presentation layer, business logic layer and data persistence layer.

Abstract: Buddy algorithm is one of the classical algorithms for Linux Memory Management. In buddy algorithm, free memory blocks, even if they have the same size and consecutive address, they cant be combined into a larger memory space because they dont have a partnership. For these shortcomings of the algorithm, this paper proposes an improved buddy algorithm which mainly include in the main data structure adding an array and a variable respectively to record the starting address and the number of two adjacent free memory blocks which are in the linked list of last order and do not meet the partnership, at the same time, improving memory allocation management and memory recovery management.By experiment, when the memory space is insufficient and memory allocation request is frequent, the improved algorithm can effectively reduce the number of failed memory requests and improve the memory utilization.
