Abstract: The peripheral malfunction will cause the nodes fail to work when there is no central control node in the large scale sensor network. The network cant guarantee the continuity of the communication and service and the communication efficiency will be low in this situation. In order to fix the issue, the paper proposes a correcting fusion algorithm for the sensor network data communication. When the collision of the communication data happens in the sensor network due to the failure of the nodes, the correcting fusion algorithm can ensure the effective data fusion between the fault nodes and other nodes to guarantee the communication to the maximum extent. The experiment indicates the algorithm can increase the efficiency of the sensor network to achieve the satisfactory results.

Abstract: Combining distributed computing and data mining techniques, a distributed personalized search engine is put forward to solve the the problems current search engines faced. It has described the theoretical model and algorithmic processing. Under the Hadoop, a distributed platform processing information with Java, the key parts are programmed and implemented. The experimental results show that this theoretical model can improve the accuracy and speed of the user's queries so it can improve the retrieval performance of the search engine.

Abstract: This paper combined with computer graphics and related spatial information sciences technologies, made use of the software Vega Prime, On the basis of three-dimensional modeling of Nanchang HangKong University campus, built a campus three-dimensional visual simulation software, which can achieve the campus landscape, zoom, rotation, scaling, flight roaming and static and dynamic simulation capabilities, such as the fountain, lake, pedestrians, vehicles, etc. The use of this technology has great importance on school enrollment, employment, education, alumni relations, showing the school strength and other aspects.

Abstract: Due to the increasing frequency and intensity of marine monitoring tasks, the need for a comprehensive information management system for marine monitoring to organize and implement all types of marine monitoring tasks is growing. This paper put forward an integrated information management system for marine monitoring using office automation (OA) technology which is based on service-oriented architecture (SOA) workflow. The system realized the management of monitoring tasks in all aspects and the statistical analysis of data. And it informationized the set of processes required.

Abstract: The paper introduced a method eliminating the influence of cloud shadow in TM image by using the bands ratio and linear transformation. The result shows the method is very effective, especially on enhancing the image contrast and improving the detail information in the shadow.

Abstract: The phenomena often appears that sea surface is above land, island is under sea surface and distortion of building inter-island in conflux area of water and land when creating three-dimensional image using fusing DEM and image. The paper introduced a fast method of modifying DEM and creating three-dimensional image in the batch by using PCI software. This method was validated by using SPOT5 and DEM in the Zhoushan area. The results showed that PCI could accurately mask the target objects and modify DEM in the batch; the result could be showed in three-dimensional mode by setting many parameters and meet different requirements; the results could fly by setting given route; the file was organized in a systemic mode, which will facilitate management.

Abstract: By making small adjustment to general ad hoc network architecture, we build a network topology with short average path length and high clustering coefficient, which are two important metrics of ad hoc networks. Furthermore, an efficient probabilistic flooding routing algorithm is proposed based on this network model. Simulation results show that this architecture behaves better performance than its ordinary counterpart.

Abstract: In this paper, the authors carry out an introduction to the principles of implementing serial port communication by Android mobile and give a detailed explanation to this implementation process through a case. In other words, through .NET serial port communication realizing serial port communication between PC and control equipment, and then Android mobile delivers control signals to the PC serial port by way of Socket communications.

Abstract: A wireless ad hoc network is a self-configuring infrastructurelessh network of mobile devices connected by wireless. In order to support the basal networking functions like routing and packet forwarding, the nodes in wireless ad hoc network should be cooperate with each other due to the limited range of wireless transmission. However, nodes are unwilling to relay packets for others considering the poor energy and bandwidth especially in the open community environment. Some approaches to stimulate nodes cooperation have been introduced recently. In this paper, we provide a novel method based on cross-layer design to solve the cooperation issues both in Mac and network layer. The method with the help of reputation mechanism and utility function based on game theoretical approach can promote nodes to cooperate and make the whole network to reach Nash equilibrium.

Abstract: Clarification dialogue is an efficient and direct way of handling speech recognition errors in speech interface applications. In this paper we present a new approach to Clarification Question (CQ) generation. Monolingual phrase-based SMT (PB-SMT) framework is introduced to generate robust and flexible CQs. A parallel corpus from simulated error to manually annotated CQ is established and used for training the model. A new type of generalized phrase pair is expanded from conventional translation phrase table. Combining both generalized and conventional phrase pairs, a two-step decoding process is carried out to generate CQs. Both manually and automatic metrics are used to evaluate the quality of generated CQs. Experimental results show that our method can effectively generate reasonable CQs form miss-recognized utterances, and generated CQs can be used to prompt a clarification dialogue for error handling.
