Abstract: This paper investigates the connotation of Taoist aesthetics and applies it to the creation of public art on campus so as to help the campus take on cultural and aesthetics connotation. It also points out that with the influence of Taoist aesthetics public art on campus is of rich aesthetic connotation, which mainly consists of the harmony between man and nature, harmony and coexistence and the beauty of harmony.

Abstract: In this paper, a integrated control system based on the LonWorks fieldbus to the application of LED public lighting has developed. Advanced control strategy of lighting energy saving has realized in this integrated control system, in order to improve the effect of lighting energy saving and management level. The control network of LED lighting and the specific techniques of integrated control system are mainly focused, including data acquisition, development of lighting control node based on LonWorks, design of lighting control network, implementation of energy saving and management strategy, monitoring and data management of the lighting system. Finally, to verify energy saving effect of the control integrated system and its high efficiency, three campus’s roadway lighting of GuiLin university of electronic technology is taken as the simulated object.

Abstract: This paper researched on vehicles’ emissions in Nanjing based on IVE model and presented the method to quantify the main inputting parameters of IVE model. This research has collected the traffic of different types of roads in Nanjing. The light-duty vehicles, taxis, buses and trucks respectively accounted for 73.4%, 13.3%, 10.3% and 3.0% of the total traffic volume. According to vehicle driving condition data collected by GPS, the driving cycle of light-duty vehicles in Nanjing was defined. The on-road vehicles’ emission data were measured using the on-board vehicle emission analyzer made by ourselves. Then the correction factors of NOx in IVE model could be obtained using the testing emission data. The results of IVE model showed that the daily NOx emission of light-duty vehicles, taxis, buses and trucks in Nanjing city were 17.79t, 5.51t, 146.37t and 83.78t. Buses and trucks were the main emission sources of NOx, with the contribution of 57.75% and 33.06%.

Abstract: “Virtual architecture” is a combination product of architecture and information science, the paper introduces the features of virtual architecture system from its application implementation, and discusses in depth the key technologies from building life cycle, such as BIM technology, notology, digital photogrammetry, virtual reality and parametric design, which hope for borrowing ideas on its implementation from the paper.

Abstract: This article compares the differences of evaluating the same environment between professional personnel and unprofessional personnel whose culture backgrounds are different. It uses the method of Subjective Evaluation of Built Environment and modern mathematical statistic. This evaluation object is the campus of Three Gorges University, in Hubei. The comparison adopts these methods such as average values comparison, one-way variance analysis, and regression analysis. According to the evaluation result, it analyzes the differences of the two groups about understanding environment.

Abstract: Based on the traditional David Jolley nine body stochastic simulation model, this article has designed a number of simulation programs of different drawing interval and refuse content. Research indicates that of top coal drawing body in this model upper width compared to lower width is small 1.3 ~ 1.7m, with the top coal drawing rate 50~71%. Improve the traditional stochastic simulation model of fully mechanized top-coal caving, considering temporary retention problems in top vacancy diffusion and horizontal fill issues in module. Under the same working face condition, it additionally builds the improvement simulation programs of different horizontal fill probability. Research shows that 10% increase in horizontal probability, the top coal drawing amount increases 2.2%. When horizontal fill probability reaches 30 to 40%, the top coal drawing ellipsoid body grows to be perfect.

Abstract: The short mullite fibers were manufactured by andalusite mineral raw materials of Mei County China through isothermal sintering process between 1350°C and 1550°C under the oxidation atmosphere. And then the process which andalusite mineral raw materials of Mei County China had transformed into short mullite fibers was analyzed by X-ray automatic powder diffractometer D/MAX-2400, and the property of morphology of short mullite fibers was observed by scanning electronic microscope QUNATA200. The result manifests that in the range of experimental temperature, andalusite mineral raw materials of Mei County China fully transforms into mullite phase after the specimen is kept warm for 3 hours under sintered temperature 1450°C, and the mullite phases which are transformed at sintered temperature 1450°C mostly present in the form of short fiber while the temperature naturally cools to room temperature with furnace, and this kind of short mullite fiber has the best crystallinity, and the least structural defect and the highest length to diameter ratio.

Abstract: Crumb rubber modified asphalt can not only improve asphalt pavement performance, but also can achieve the waste re-use, further study on the crumb rubber modified asphalt is very important. This paper mainly discusses the action mechanism of waste tire rubber modified asphalt, and analysis the performance improvement of the asphalt when it is mixed with the waste tire rubber. By analyzing the test results of asphalt’s conventional, we find out that mixed the waste tire rubber in asphalt is the resulting in the improvement of asphalt’s performance. Lastly, it discusses waste tire rubber modified asphalt advantages and the prospects of development. Overall, popularize and application the asphalt-rubber mixture is valuable.
