Abstract: According to the solar LED lights characteristics, combined with ZigBee technology and ATmage128L microprocessor. A used in street light control system for wireless sensor network technology solutions, given the sensor nodes and ZigBee routing and the coordinator node hardware and software implementations. The applications show that the system can effectively improve the LED streetlight system reliability, safety and economy. Offers a good hardware platform for wireless sensor networks applied research.

Abstract: American universities information security management system mostly established a special and independent information security management. Management system establishes the most CI0 management system, perfects the organizational structure and management content, which emphasis on differences, but the content covering were roughly the same. Enlightenment is as follows: first, we must establish independent information security management department. Second, we must be standardized, information security management content; Third, we must be installed with the professional information security work team.

Abstract: The overhead brings by metadata journaling is extra space and performance degrade caused by frequent journal data flush. A journal file system based remote journal scheme was designed and implementation. The remote journal scheme removes the frequent journal I/O activities from local disk to remote server. According to the experiments in this paper, remote journal increases about 8% to 19% performance, but the penalty is light. Although remote journal does need more CPU time for network transfer, the overhead is less than 8%. And the extra network bandwidth taken by remote journal is less than 6% in metadata bound workload.

Abstract: In order to improve the quality of the reconstruction of the object boundary is proposed based on false parallax variable block-size stereo image coding scheme. The scheme of the size of the image in pixels can be according to the grey value of the absolute difference and change. If a image block grey value of the absolute difference than the threshold value, the piece may need to be divided into four 4x4 sub-block. If less than threshold, is not divided.The experimental results demonstrate that the proposed algorithm is effective, this article puts forward a coding scheme to promote the application of three-dimensional images is of great significance.

Abstract: This paper introduced the design and implementation of management information system based on WEB. The essay regarded the transformation of the old and the new rural social pension insurance system and the establishment of the new rural social pension insurance system as the main research object, designed and developed the information management through the structural design, technical support, selection of WEB database, WEB application server, programming system options, operation process and so on.

Abstract: This paper first discusses the limitations and shortcomings of data mining under the conditions of massive data. Combined with the advantages of cloud computing, a data mining architecture for cloud computing is designed, and on this basis, the paper discusses the improvement of data mining algorithms for cloud computing. As a theoretical exploration, the paper proposed useful suggestions for the optimization of data mining in face of cloud computing.

Abstract: In recent years, the virtual-reality simulation technology has developed so fast which has been widely used in military and people’s daily lives, etc. As the essential element of the three-dimensional scene, modeling of trees becomes increasingly important. There are many methods for 3D modeling trees such as 3DMAX modeling, the bulletin board technology, the crossing panel and the LOD technology. However, these methods are not so effective either for the bad real-time performance caused by the large quantity of data or the unsatisfactory 3D effect. Therefore, this paper is aiming at proposing a 3D tree modeling method which was based on the combination of Fractal and Non-rectangular raster image technology.

Abstract: Recently, some proposals suggest to use a peer-to-peer network instead of servers to facilitate SIP user registration and location in IMS communication systems. Due to the lack of central authority, security issue becomes one of the main problems in such P2P IMS systems. In this paper, we propose a novel security architecture for P2P IMS system. By using this architecture, our P2P IMS system becomes a fully distributed secure system in which there is not a central server indeed. Furthermore, our system is a scalable system which is capable of anonymous yet accountable real time communication based on SIP protocol which enables the system compatible with any existing IMS systems.

Abstract: The rig is widely used in coal mining production, its research and development, manufacture and use are required to test the performance indicators. For this, the paper researches and developments the comprehensive performance automatic test system in coal mining rig by using virtual instrument technology, and detailedly discussed the hardware configuration and software design scheme of the test system. After a hundred sets of various types testing and inspection of rig, the operation results shows that the automatic test system can meet the various performance parameters’ testing requirements of the split and crawler rigs, and greatly simplify performance testing program of rig, improve the test efficiency.

Abstract: In recent years, the home environment has seen a rapid introduction of network enabled digital technology. This technology offers new and exciting opportunities to increase the connectivity of devices within the home for the purpose of home automation. The use of wireless technologies in automation systems offers attractive benefits and in the same time introduces a number of new technological challenges.Wireless sensor networks (WSN) have recently been proposed for a large range of applications in home and industrial automation, and for health and environment monitoring. ZigBee standard is getting more and more attention as it can be used to implement wireless sensor networks for its low data rate and low power consumption. There are a large number of reseaches dealing with WSN applications, but it is still possible to explored in WSN development and maintenance. Based on the integration of WSN and the service robots, this paper implemented a home automation application. In this work the service robots can be considered to be mobiles nodes that provide additional sensorial information, improve/repair the connectivity and collect information from wireless sensor nodes. And the WSN provide a smart environment for the service robots.
