Abstract: In order to improve measuring-temperature accuracy of the PT100 temperature sensor, we conduct multi-point calibration experiment. The BP neural network based on LM algorithm can process experimental data and the least square method can fit out more accurate formula that express the relationship between the temperature and resistance. It is available that this arithmetic that the interrelated experiment demonstrate its accuracy improve precision of the PT100 temperature sensor.This arithmetic can be applied to the calibration test.

Abstract: With the rapid development of mobile ad hoc network, energy and trust are important to the network. Energy consumption and trust routing scheme are the main issues in mobile ad hoc network. Trust routing is related to many factors such as hop numbernode residual energy and node behavior. To use the multi-source information, multi-agent information fusion method is used to design trust routing scheme. The definition of trust routing is proposed. Ad hoc On-Demand Distance Vector (AODV) routing protocol is used to validate trust routing scheme, Route Reply (RREP) Message is extended to record node residual energy and behavior information. NS-2 simulator is used to simulate different network scenarios. Simulation results show that low power trust routing scheme can improve the security and efficiency of network, the scheme is sensitive to node residual energy, so it extends the service lifetime of the network.

Abstract: A kind of detection and location method for the network traffic anomaly focusing the wavelet analysis was proposed in this paper on the signal feature and self-similarity of the network traffic in the enterprise. The method can effectively detect the network traffic anomaly and locate the anomaly point through the simulation and verification of the data collected in DipSIF platform.

Abstract: Rough Sets (RS) networks and expert system theory were applied to the photoelectric equipment fault diagnosis, and the intelligent diagnosis expert system was built. The accuracy and efficiency of photoelectric equipment fault diagnosis were significantly improved by using of the RS and networks. With combined RS theory with networks, photoelectric equipment fault implementation was optimized and simplified during the training of sample set.

Abstract: Reversible logic synthesis has become a fast developing area. In order to construct reversible logic gate network, this paper presents an algorithm of iterative construct reversible network by cascade operation. The cascade operation was implemented with Boolean permutation. We proposed two important decision condition of Boolean permutation, and changed to choose balance function of suffice Boolean permutation condition for the problem of construct reversible network. The result of algorithm analysis show that it is can be implemented fleetly.

Abstract: Through the analysis of the hypertext markup, proposed and implemented several new methods of text information hiding. The concealment of these methods is better, Comprehensive utilization of these methods can obtain large information hiding capacity, better concealed. And they have better robustness for traditional attack.

Abstract: Usually the support environment for network teaching needs establishing in short time for numerous training activities. In order to meet the general requirements of many trainings, a relatively complete network teaching system is designed based on B/S mode and with adoption of ASP.NET and C# etc. key technologies and programming language, achieving the rapid transfer, sharing and communication and effective management of teaching information. The method can rapidly construct the network teaching environment with such features as universality, convenience, economy and expansibility etc.

Abstract: This paper proposes a communication scheme for heterogeneous wireless and wired sensor networks. In the scheme, through a common protocol to shield the differences of different types of wireless-wired networks, to realize the mobility management for heterogeneous wireless and wired network environment. In addition, access technology of the second layer can be shielded, and provided a unified interface for upper protocol layers. From the theoretical and simulative perspectives, the paper analyzes the performance parameters, including the mobile function, throughput capacity, energy consumption and network lifetime, and the analytical results show that the performance of the scheme is better than other mobility management scheme.

Abstract: This paper has searched the six key influential network group incidents in 2011 in China through SINA Microblog platform, screen the most active Microblog users who pay close attention to the incidents, their Microblog followers are above 50,000 , finally collects 30 Microblog user information by the way of snowballing, form 30*30 “follow – be followed ” Microblog netizens relationship matrix. Specific to this asymmetric matrix, the authors use UCINET social network analysis software and visual software NETDRAW, analyze Microblog network structure, network centrality based on network group incidents, and comprehensively describe the laws to release and acquire group incidents under the mixed network environment of Microblog, combined with the massive Microblog exchange data, to analyze the non-rational behavior of the netizens, so as to provide a scientific basis for setting out the appropriate guiding strategy and interventions.

Abstract: Applying the electronic technology simulated software to internet remote teaching platform has very important significance for expending the function of simulated software and creating new mode of remote practice teaching. This article introduced research results and development idea of electronic technology simulated practice training platform which based on Proteus.
