Abstract: with the rapid development of information technology especially Ipv6, people become more and more dependent on internet and some related applications. yet some security intrusion vary from minor mischief for pleasure, denial of service, and criminal intent for stealing or destroying still threat the security of information system which provides service online. Traditional researches on intrusion tolerant mainly focus on Ipv4, which cannot satisfy the requirement of Ipv6. Regarding this problem, the architecture of intrusion tolerant system based on Ipv6 is designed and some critical modules are improved accordingly, the workflow of the system is described in detail. The validity of the system is proven by the result of simulation experiment.

Abstract: In this paper, we aim to the digital watermarking technology comprehensively and basic framework of digital watermarking system. Also, attack technology on watermarking systems and performance indicators are discussed. By analysis, we proposed mage digital watermarking algorithm based on integer wavelet transform and give some advantages of this algorithm in applications of digital watermarking technology.

Abstract: This paper refer to weight as objective and subject to multiple response amplitude of the harmonic excitation. The ICM method is employed for solving the topology optimization problem and dual sequence quadratic programming (DSQP) is effective to solve the algorithm. A numerical example was presented and demonstrated the validity and effectiveness of the ICM method.

Abstract: Single task learning is widely used training in artificial neural network. Before, people usually see other tasks as noise in same learning machine. However, multitask learning, proposed by Rich Caruana, sees simultaneously training several correlated tasks is helpful to improve single tasks performance. In this paper, we propose a new neural network multitask similarity cluster. Combined with hellinger distance, multitask similarity cluster can estimate distances among clusters more accurate. Experimental results show multitask learning is helpful to improve performance of single task and multitask similarity cluster can get satisfactory result.

Abstract: Aiming at energy consumption problem in the ZBR hybrid routing algorithm, an improved algorithm (W-ZBR) based on ZBR routing protocol is proposed to reduce the network energy consumption. The algorithm was improved mainly from the following parts: Cluster-tree routing algorithm and AODVjr routing algorithm. In Cluster-tree routing algorithm the redundant packet of RREQ is limited to reduce energy consumption by setting the parent node id. In AODVjr routing algorithm the network energy consumption is balanced by monitoring the remaining energy of nodes. The simulation result indicated that W-ZBR performs better than ZBR in remaining energy ratio, routing overhead ratio, available node ratio and packet delivery ratio. The algorithm can also prolong the life span of network.

Abstract: We adopted the form of questionnaire survey to interview some college graduates, got six factors that influenced graduates job choices and the importance among these six factors ,then built a model and evaluated these factors based on AHP and passed the consistency check, then concluded that such method has practical acceptability. Finally, as one of the applications of such method is presented.

Abstract: It is necessary to consider the energy efficiency of nodes and load balance in wireless sensor networks. This paper combines with the network of the actual heterogeneous nodes, the improved algorithm of LEACH is proposed, which is called LEACH-HA. The optimal number of cluster heads is derived with improved in the network which increases energy of nodes become cluster probability. A hybrid communication mode that cluster heads alternate between single hop and multi-hop mode is proposed. After analysis LEACH-HA improves the energy efficiency among nodes and expands the coverage of network.

Abstract: The design of records management information system should take into account the features of information technology and the special requirements of records management to guide the design of the system with a brand new idea. Through the analysis of functions of network-based records management information system, this paper made an in-depth study on the system architecture, logical structure, and data storage and optimized and adjusted the data model combined with specific development needs and development environment. It also provided the specific solutions and technical measures on the records management information systems with numerous and complex data information.

Abstract: In order to make the users who didnt study the computer-related major can find the useful information in their familiar manner, it becomes a hot research topic to search in an interactive way using Chinese natural language. But because the complexity of Chinese, how to build of a formal model of natural language is always a difficult research problem. In this paper, by analysis the query sentence type in SQL based on the special database, we bring forward the rules and the context irrespective grammars of the restrictive Chinese that resolves the difficult comprehension problem in natural language processing. And aiming at the comprehension processing, we give the detailed arithmetic describing that can translate a natural language query of the restrictive Chinese to SQL.

Abstract: As an important part of FTTx network, ODN is facing the challenge to better management on large mount optical fibers and ports. Intelligent ODN is a promising solution with automatic deployment and management. Technical solutions are well developed, and part of its standards is in process. But the test consideration is still blank. Based on our study and real network operation experience, we firstly provide a suit of test methods on the evaluation of Intelligent ODN networks.
