Abstract: Environmental pollution caused by rural domestic wastewater has become increasingly serious. However, data on the current characteristics of rural domestic wastewater are scarce. In this study, we selected typical villages along the Tuojiang River as study objects. We analyzed the pollution status and discharge characteristics of rural domestic wastewater along the Tuojiang River through field research in winter and summer. Data analysis and collection, as well as water monitoring, were performed to determine the water quality and quantity characteristics of the rural domestic wastewater. The per capita daily discharges of rural domestic wastewater along the Tuojiang River are 11.26–50.37 L in winter and 18.39–303.57 L in summer. Both the maximum and average concentrations of pollutants in the rural domestic wastewater are higher than those in urban domestic wastewater, but the per capita daily discharge of pollutants is clearly lower in rural areas than in urban areas. The analysis of the typical discharges of rural domestic wastewater along the Tuojiang River provides a valuable reference for rural wastewater discharge treatment planning and process selection.

Abstract: Requirements Traceability has a very important role in the entire application development lifecycle. As for the problem of manual creating requirement traceability relationship time-consuming and error-prone effort problem, this paper proposed a new component-based dynamic requirement traceability model. The model incorporates the requirements specification model and component functionality tree model to format requirements documents and component library. Establish requirements traceability relationships through mutual matching between component facet functional items and requirement documents. Validate requirements traceability feasibility and efficiency through multiple systems and component requirements documents, the experimental results provided by the implemented system show that the model is valid, and efficiency and accuracy have been improved to some extent compared with the conventional information retrieval model.

Abstract: In this paper, based on the status quo of plastics extrusion production process at the present stage in China, put forward on the basis of general embedded industrial control scheduling expert system for optimizing the process parameters is established. Structures of the expert system, user interface, the establishment of a knowledge base, reasoning machine design, the learning machine design and so on are introduced. System can according to customer's production goal reasoning out the required process parameter values, and has good portability, instead of the professional engineers for plastics extrusion production process parameters manually, save the human cost, improve the intelligent level of automation and production efficiency.

Abstract: This paper evaluates the environmental art design based on digital technology by analyzing its digitalization and level as well as the design process. The analysis on the straight line and free curve composition rules of digital environmental art and the verification of its feasibility provide new design strategy for environmental art design.

Abstract: Machine element survey is a process by measuring, drawing, analysis, design according to existing elements, finally drawing the formal pattern of the element. The method that the operator used to deduce the original design dimensions based on measured value analysis is called dimension roundness. It includes the measured data processing, defining the basic dimensions, tolerances, limits and fits type. Base on years of teaching, experiment, analyzing and practical producing experiences, I found that the dimension roundness and the presentation or definition of related elements in all textbooks were inexact and unreasonable. It influenced the effectiveness of higher vocational education. This paper analyzed advantages and disadvantages of several dimension roundness methods, and then put forward the innovative practical roundness method. I revised the unconventional design dimension roundness; and pointed out that no matter using what roundness method, result diversity always exists.

Abstract: Workflow technology continues to be subjected to on-going development in its traditional application areas of business process modeling and business process coordination [ .It can improve the efficiency and manageability of an enterprises daily teamwork .Traditionally, it is not easy for the workflow modeling method to describe the complex business process clearly and intuitively [ .In this paper ,we improve the role based workflow model and introduces definition and enactment models to characterize workflows. In the way ,flexible modeling and enactment of business process is supported allowing changes even during execution.Finally,an example of Financial Reimbursement System is demonstrated to prove the convenience and feasibility about the method mentioned.

Abstract: In this paper ,we explored the new method of urban design modeling based on a new rule-based parametric modeling software: CityEngine. Through combining the technology of CityEngine and ArcGIS, we can solve the problems existing in traditional urban design: complex modeling process, poor 3D visualization, low efficiency of modification and poor public participation, and can expand the new technique applications in urban design.

Abstract: Preliminary exploration on simulation data mining with BP network and rough set method is made in the paper. Data mining method based on rough set theory and BP neural network is put up. Firstly, we reduce the redundant attributes in the decision-making table with rough set method, and then the noise is filtered by BP neural network. Finally, rule set is generated by rough set from the reduction decision table. This method not only avoids the complexity of the rules extracted from training the neural network, but also improves the classification accuracy effectively. At last, the mining data by the experimental data of the troops marching warfare simulation system and the result with the actual reference value is obtained.

Abstract: This paper takes microblog as an example, recognising names in finance and economics field by the algorithm combining the use of rules and probability calculation. This method firstly get the candidate names through calculating the probabilities, then choose from the candidate names by matching them with corresponding rules which contain positive rules and negative rules .This method has good robustness and flexibility.

Abstract: The design load plays an important role in research on structural analysis of surface warship. The methods for the design loads have been proposed by many famous classification societies rules. In this paper the methods of the design loads from the native existing classification societies rules and foreign rules were studied, and based on these rules, the design loads of a warship were obtained. Meanwhile, segment model self propulsion tests of this ship were performed in heading waves in the seakeeping tank to confirm the design values. Comparisons of calculation of classification societies rules with experimental data were also conducted and results were summarized in this paper. It is concluded that the evaluation methods from the rules don’t take full account of the importance of slamming，the slamming moments from rules are fewer and wave moments are too large while those from BV rules give relatively conservative design values for the surface warship.
