Abstract: Dairy products logistics service quality directly affect the quality of dairy products, this article first from management level, advanced technical equipment, warehousing and distribution quality, cost economy four aspects put forward the preliminary evaluation of dairy products logistics service quality, then through questionnaire survey to judge the proposed initial indicators of evaluation, through the analysis of the membership degree and the important degree of initial index screening optimization, get a more scientific and reasonable evaluation index system, lay a solid foundation for the objective evaluation of the dairy products logistics service quality.

Abstract: Now, college graduates’ employment situation is serious increasingly, and it has become the focus of society. This paper first analyzes the connotation of college students’ employment competitiveness and the necessity of enhancing college students’ employment competitiveness. Finally, it summarizes several approaches to enhance college students’ employment competitiveness.

Abstract: Because other consequential damages brought about by the construction delay can not be estimated, so the guarantee period or even ahead of schedule becomes particularly important. The critical path usually determines the progress of the construction. However, because of its own deficiencies, the traditional critical path algorithm cannot accurately describe the overlap between activity and interaction. So, in the paper, matrix method for critical path (CPMM) is designed for CP, and its rules and calculating process are described in detail. Through experiments, the effectiveness of CPMM is proved.

Abstract: This paper establishes a power planning model based on minimization of the initial investment cost. The model includes the initial investment cost of wind turbines, photovoltaic cells, batteries, and biomass generators, diesel generators, power electronic devices and communications facilities in the objective function. In consideration of some constraint conditions, using the principle of priority of biomass generators, we use the particle swarm algorithm to solve the model. Through the calculation of actual examples, we simulate to find optimal solutions. Finally, we conclude that it should be possible to use biomass power generation and diesel generator power.

Abstract: The tradition packet channel multiplexing control algorithm of Advanced Orbiting Systems has the obvious disadvantages such as high time delay, high packet loss probability and low system throughput. Those depress the capability of the space communications badly. Based on the packet parameters, a new packet channel multiplexing control algorithm is proposed to optimize the tradition fixed multiplexing time. Under the prerequisite to ensure the maximal multiplexing efficiency, the processing time of packet channel multiplexing is limited, the packet loss probability is depressed, and the multiplexing throughput is advanced effectively.

Abstract: Geological disasters practical work requires accurate extracted data and convenient cartography. This paper couples the essential features of AutoCAD and MAPGIS. The multi-analysis is supposed to pay attention to both graphic data characteristics and the graphic data switching process. This process and method elaborates and transforms AutoCAD DXF and DWG graphic data and the MAPGIS MPJ graphic data, in order to enable the existing geography information resource obtain the full usage of graphic data coupling.

Abstract: Current emphasis on practical teaching, students creative thinking higher vocational schools teaching philosophy, the traditional manual management mode of the computer training room shows weak features, mainly for equipment maintenance cycle length and the contradiction between the teaching needs. From teaching management, equipment maintenance, environmental management, safety management, explore computer-based training room sensor network management model.

Abstract: In online shopping, studies on consumer reviews are mostly based on the Attitude Change Model. Illustrated from the perspective of perceived trustworthiness, however, it is not easy to measure and characterize the subjective perception of consumers. Starting from the inherent property of online reviews and based on the real data of 360buy which is the domestic large-scale B2C commerce website in China, this paper focuses on the interval distribution of consumer reviews and the data for statistical analysis. Research finds that the distribution of reviews interval can be depicted by the power-law function and there is a monotonically increasing relationship between power-exponent and the customers concerns with the commodity, the higher exponent, the attention consumer get. The findings give an objective basis to judge the credibility of online reviews. The relationship between power-exponent and the consumer attention has demonstrated the vital role of consumer attention in online shopping, and then the double parity between attention and exponent will effectively regulate the e-commerce market environment and promote its healthy operation.

Abstract: In this paper we designed a set of driving process in order to achieve the IPv6 network connectivity between the isolated IPv6 islands which can instruct tunnel packet to forward on the chips. First, it introduces 6to4 tunnel, system structure and the process of chip forwarding. Then it introduces how the drvier respond to the platform and write the correct message on the chip after processing. Experimental results show that the driving process can instruct 6to4 tunnel packet to forward on the NP chip very well. The result is good and has strong practicability.

Abstract: In this work was carried out modeling of organic polymer materials for gas sensors on the example of a homogeneous polypyrrole and polyacrylonitrile with metal silver. The implementation was carried out by modeling the Wang-Landau and entropic Monte Carlo simulation based on a model with a fixed valence angle. To simulate the polymerization process using an algorithm based on the principles of irreversible aggregation of Eden. Methods of quantum chemistry has been investigated and the possibility of obtaining property silver-PAN and polypyrrole
