Abstract: Through BBR, DTT and independently developed Asphalt Thermal Cracking Test, several asphalt low temperature performance indexes(SHRP critical cracking temperature, Asphalt Thermal Cracking temperature, SHRP creep stiffness, m value, conventional ductility) were evaluated. The TSRST test was used as low temperature evaluating standard indicator. The theory of grey correlation is adopted to reach that TSRST fracture temperature has the highest correlation degree with Asphalt Thermal Cracking temperature. The SHRP critical cracking temperature has the second place of correlation degree with TSRST. Low temperature ductility has the lower correlation. Therefore it is more reasonable to adopt thermal cracking temperature than other general evaluations.

Abstract: Looking back at the historical process of urban and architectural development, people can clearly see that the light technology and light culture synchronized with the development of cities and architecture, and they can also see what an important role that technological advances of daylight illumination have played in cities and appearance of the architecture as well as modern life. With the development of economy and improvement of the living standards of human, the landscape lighting at night has been rapidly developed, and has made brilliant achievements. In recent years, the city government attaches great importance to city lighting work, taking the construction of city lighting project as an important measure to improve and beautify the city environment. However, the problem of light pollution attendant should be worthy of attention as a serious problem

Abstract: The Qinghe and Fanhe basin in Tieling, Liaoning were studied as case in this sduty. The COD emission reduction was assigned by the method of information entropy and the Gini coefficient method first. Then the correlation between the calculation methods and the water environmental quality was analyzed. Finally, the best method of reduction calculation was identified. The results showed that the information entropy method was a better method in total allocation because it was highly correlated with water environment quality,at the same time it combined the pollution reduction and water environment quality management better. The results also showed the COD reduction in Qinghe basin was larger than Fanhe basin, so the Qinghe basin was the focus of emission reduction. Key words: Information entropy method;Gini coefficient method;COD emission reduction assignment;Correlation

Abstract: The SO2 concentration can be figured out through measuring the light intensity attenuation. But the scattering and absorption of the multidispersion soot particles can attenuate the light intensity, so the visible measurement light intensity attenuation is larger and the concentration is increased. The interference on the SO2 concentration caused by the multidispersion soot particles is discussed in this paper. The dissipativity, concentration, average size, size distribution parameters and the scattering light angle range of the multidispersion soot particles can interference the SO2 concentration.

Abstract: SO2 is one of the most important atmosphere pollutants which can be figured out by measuring the attenuation of the visible light intensity on the characteristic wavelength. But the visible light intensity is also attenuated by the monodispersion soot particles because of the particles absorption and scattering. The interference of the monodispersion particles is discussed in the paper. Simulation results show that the impact parameters on the SO2 concentration accuracy include the received scattering angle range, particle size and concentration. According to the study SO2 concentration measurement accuracy can be improved

Abstract: With the aggravation of water resources scarcity in northeast China at present, the area of the wetlands in the watershed has gradually decreased, and the ecotope is getting worse. In this article we take Xianghai wetland and Zhalong wetland as an example to study the process of ecological water requirement, so as to provide the basis for water environment protection. The results show that the suitable ecological water requirement of Xianghai wetland is 191.19 million m³, and the minimum ecological water requirement of Xianghai wetland is 74.32 million m³. While the suitable ecological water requirement of Zhalong wetland is 559.63 million m³, and the minimum is 217.39 million m³. The wetlands in northeast has four ecological water requirement characteristics, which includes that the northeast wetland ecological water requirement process assumes an M type; May is the month having the highest ecological water requirement of the wetland; the wetlands’ ecological water requirement shows a sharp decline in July; and the wetlands ecological water requirement becomes less in winter. The wetlands should choose a right time to make an ecological water supplement for the wetland, in order to alleviate the water shortage condition, and maintain the wetlands’ structure and function to play them normal roles.

Abstract: In this study a food company in the production of sauerkraut pickled wastewater as an object, using the anaerobic biological filter and biological contact oxidation pond process, feed water salinity, HRT are investigated, and the effects of each process. The results showed that anaerobic biological filter when HRT is 36 h, the COD removal rate can reach 81%. Biological contact oxidation pool when HRT is 60 h, when the COD removal rate reached 85%. Anaerobic biological filter - biological contact oxidation coupling process of pickling wastewater removal effect is obvious, after processing salted COD removal rate reached 88%.

Abstract: The distribution of arsenic speciation can be applied to elucidate the mechanism of removal arsenic during treatment the water containing arsenic with molysite. In this study, the effect of initial pH on the distribution of arsenic speciation in arsenic-ferric precipitation was determined by a five-step sequential extraction procedure. And then further explore the mechanism of arsenic removal with molysite. This experimental results showed that the main mechanisms governing the arsenic removal with ferric chloride were specific adsorption and coprecipitation. Besides, as pH increased from 5 to 9, the arsenic-ferric coprecipitation played a more and more important role in mechanism of arsenic removal with molysite. At the same time, the water soluble state As and the non-specific adsorption As were barely detectable, which suggested that physical absorption had almost no effect on arsenic removal.

Abstract: Community is based on a certain region of the community of human life. In the face of increasingly serious ecological crisis, a benign living environment has became the urgent need for human beings. Under the guidance of sustainable development and ecological civilization concepts, as well as relying on the paths of applied-information technology,Low-carbon industry,low-carbon transport and low-carbon consumption, we can establish an evaluation index system from low-carbon buildings, low-carbon production, low-carbon transport, low-carbon consumption etc.by the Delphi method and analysis hierarchy process (AHP), so as to promote the development of Hengyang low-carbon community.

Abstract: This paper presents a novel approach for simultaneous localization, mapping (SLAM) and detection of moving object based on information fusion. We use different information sources, such as laser range scanner, and monocular camera, to improve the ability of distinction between object and background environment. The approach improves the accuracy of SLAM in complex environment, reduces the interference caused by objects, and enhances the practical utility of traditional methods of SLAM. Moreover, the approach expands fields of both research and application of SLAM in combination with target tracking method. Results in real robot experiments show the effectiveness of our method.
