This paper proposes a novel approach to evaluate development level of regional industrial economic. To promote the performance of the original neural network, we present a hybrid neural networks model based on a fuzzy regression model, and then apply this model in regional industrial development level evaluating. The proposed algorithm is made up of three steps, which are (1) Training a network by the data from observations, and output the optimum solution, (2) Determining the minimal fuzziness, (3) The data of the proposed model around upper bound and lower bound are pruned. Experimental results show that our method is effective in regional industrial economic development level evaluating, and the performance of our algorithm in just close to the ground truth. © Springer-Verlag Berlin Heidelberg 2014.

With the development of computer and information technology, computer and network have been popular. At the same time, security problem has greatly aroused people's attention, especially in campus environment. Campus network as an important part of the campus life, people also arouse enough attention to the problems of personal computer safety management. Running a set of effective campus network monitoring software is real needed for the campus network management and maintenance personal safety. In order to ensure the safety, reliability and steady running of the campus network, according to the present situation and development of the campus network, people plan and design to use network monitoring system on the campus network security management. The system can effectively control and manage the reliable operation of the campus network. © 2014 IEEE. Source

Remote sensing classification, as an important means of urban planning and construction, has been widely concerned. Urban land use classification is extremely challenging tasks because of some land covers are spectrally too similar to be separated using only the spectral information of remote sensing image. Object-oriented remote sensing image classification method overcomes the drawbacks of traditional pixel-based classification method. It combines the spectral, special structure and texture features of the images, can effectively avoid the phenomenon of "different objects share the same spectrum" or "the same objects differ in spectrum". Support Vector Machine (SVM) is an excellent tool for remote sensing classification. Combination of both can develop their own advantages to do high-resolution remote sensing image classification. Using a public image in Harbin city as an example, classification based on object-oriented method and SVM has achieved better results than traditional pixel-based classification method. © (2014) Trans Tech Publications, Switzerland.

Based on a principal-agent model, the motivations of China's listed companies to have political connections are analyzed using Game Theory. The internal mechanism of the motivation is also demonstrated, that is, the performance of senior executives is directly exposed to the influence of political connections. When government resources are used for a trade, whether openly or covertly, the agent will perceive the political contact as a "high-speed channel" through which the contact will turn into a large profit; when the agent improves his performance and gains profit through political ties and the listed company gains profit and improves the company's value, the agent's work enthusiasm is reduced due to the political contact; thus the agent's working efficiency is decreased, which may erode the value of the listed company. © 2013 by Binary Information Press.

This paper discourses the method to improve steam temperature and analyses the feasibility to increase steam temperature in the existing saturated steam boiler. The retrofit scheme aimed at a superheater installed on SHL6.5-1.29-A?type boiler is elaborated including the investigation of installation location and structure of the superheater. In addition, the test results before and after boiler transformation are compared, by analysing the energy saving effect, the problems needing attention in transformation and operation management measures are put forward and the technology promotion field is indicated. The practical basis on boiler transformation and energy saving for enterprise are also provided. Source
