Abstract: Linear frequency modulated signal and the two-phase encoded signals are widely used in pulse compression radar system derived, based on the analysis of the two signals, a linear frequency modulated with chaotic two-phase coding complex modulated signals. Versatility advantages of simple structure, radar signal processing using DSP signal processing devices. TI's TMS320C6713 DSP as the core basis works to achieve a common structure, the composite modulation signal frequency domain digital pulse compression processing, given the realization of the system block diagram and pulse pressure results. The results showed that the composite modulation signal is easy to produce and handle, and works to achieve feasible.

Abstract: In order to enhance the resistance to interference of radar, introduced chirp and chaos BPSK two pulse compression signals principles, has analyzed the respective signal characteristics. Based on MATLAB simulation, from 5 aspect analysis and comparisons the performance of these two radar pulse compression signals. The results show that when these two pulse pressure signals can meet is big request of wide band width, the signal after pulse pressure have the ratio of high.

Abstract: The paper takes mathematical morphology into locomotive image by operating the high frequency sub image after wavelet first level decomposition, finding the license rectangular area, extracting the area position by area researching, and then further making sure the license area by line and row projecting. Keywords: wavelet; rectangular area; area researching;

Abstract: Quick and highly efficient warning is critical in any emergency evacuation. From the issuing of warning until action taken by people in response, the entire course is a very complex process which is restrained by social, economic, population and other factors. To study the diffusion characteristics of warning in the social network environment as well as the relevant influencing factors, under the guidance of complex system theory and multi-agent modeling method, this paper analyzes the six stages in the diffusion process of warning and builds a diffusion model of warning on the multi-agent software platform Repast based on WS small world network model. Through the study of the simulation results, we find that the diffusion of warning is similar to the diffusion of other information, which showed a similar S-curve.

Abstract: The use of MODIS remote sensing data desired physical concept fuel preheating energy based on data, by fully considering the heat in the ignition probability index actual transfer heat loss in the process of combining fire probability index by population density and surface roughness index. Construction of integrated fire danger index by ignite two exponential probability index and fire probability index. After the analysis of forest fire in Heilongjiang in October 12, 2004 fire points results, show that the model can obtain better forecasting results. This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text.

Abstract: As one of the major projects, urban subway plays an important role in the city development. However, therere a lot of uncertain risks throughout the entire construction process, any improper handling may lead to serious safety accidents and incalculable property damage, so it is essential to take full concentration in the urban subway risk management. This paper divided risks that may encountered in the process of subway construction into three parts, and gave advices from four aspects so as to effectively prevent and mitigate the subway risk, thus ensure the achievement of the subway construction.

Abstract: Jiangsu is a province with scarce energy resources, Binhai LNG project will guarantee the supply of clear energy and ease the shortage situation in the middle and north Jiangsu province. The project can greatly increase the GDP and prompt the development of Binhai county, it can also improve the local revenue and motivate the development of relative industries. With the entry of LNG project, peoples behaviour on energy consumption will change significantly. It will be helpful to increase the income of local people and provide more job opportunities.

Abstract: The economic loss forecasting model is built up on the basis of the Fourier series to simulate economic loss and grades in storm surge disaster of Zhejiang, Fujian and Guangdong Provinces. The wind speed can be used to forecast the economic loss of Guangdong Province, and the accuracy of trend and grade forecasting is good (80%). The wind power data can be used in Zhejiang and Fujian Provinces, and the accuracy results are both inferior (60%). Therefore, in the economic warning of storm surge disaster, the Fourier series model can be applied to forecast economic loss and grades.

Abstract: The new round economic restructuring which is caused by the U.S. Subprime Crisis proceeds in the environment of many adverse effects. Facing the new round Economic Restructuring, it is an objective requirement for Liaoning to use scientific and technological innovation to implement Revitalizing programs for ten major industries, also a very important way to ensure the emancipation from the financial crisis with the fast development of Liaoning economy. Through theoretical analysis of Scientific and Technological Innovation in promoting economic restructuring, the paper combined with the characters of the new round economic restructuring analyzes ways and contents even an index system of scientific and technological innovations promotion of economic restructuring.

Abstract: The index system for the tourism value evaluation of the urban industrial heritage was constructed from four perspectives, including the value of locational factor, value of science and technology, value of humanistic emotions and the aesthetic value of tourism. The evaluation model for the urban industrial heritage was established on the basis of matter-element model and analytical hierarchy process.
