Abstract: In this paper, according to the characteristics of the site of the urban public transport station problem, a mathematical model of the urban public transport station problem was established. A Novel Firefly Algorithm was used to solve the model, with Hezuo city of Gansu Province as example, the algorithm was experimented and the experimental results show that the novel firefly algorithm has better feasibility for the site of the urban public transport station problem.

Abstract: The gray-scale digital image is two-dimension, most of the previous polynomial fitting methods for edge detection belong to one-dimension methods. The new method of two-dimension polynomial fitting for edge detection is presented. The grey level data of the interest area around the edge in the image are fitted by the two-dimension polynomial function. The edge of interest is identified by finding the maximum of the form of gradient of the fitting function. Because the two-dimension fitting is actually more suitable for the two-dimension image, the fitting results of two dimension method are significantly better than that of the one-dimension method. It is shown through the analysis of the synthesis image that the results of surface fitting and edge identification used of the proposed method are quite good.

Abstract: Based on being a modeling process of the network learning system essentially, it has three elements of learning environment, learning, learning activities, and three dimensions of conceptual model, physical model and logical model. From the method aspect, it has analytical method, theoretical basis, model design; from logical view, it has branch learning resource, learning control management and students' interaction layer. Focus on the analysis of the learning system model of learning resources and learning system modeling.

Abstract: This study has the hypotheses of the factors influencing customer satisfaction of the website features and model, and uses AMOS 7.0 structural equation analysis to process questionnaire data. According to the path coefficients of structure model and the indices of fit that verify the hypotheses, this study reaches a conclusion that the factors affect customer satisfaction of e-commerce mainly contain website economy, website security, website informative, followed by the convenience and website interactivity, and website popularity and entertainment has little impact on customer satisfaction. Most of the hypotheses of this study are supported by empirical research. And the conceptual model that customer satisfaction of e-commerce is decided by the website service quality consumers perceived and customers expectations is set up.

Abstract: With the development of economy, online shopping has become more prominent, study found if a website has good quality dimensions will promote consumers to buy. Paper based on site characteristics, takes perceived risk and perceived emotional as intermediate variables using structural equation model (AMOS) to study consumers purchase intention. The results shown that the security impact on purchase intention by perceived risk, interactive and entertaining impact on purchase intention by perceived emotional, convenience and functionality directly impact on purchase intention.

Abstract: In this paper, according to the characteristics and influence factors of the distribution logistics and distribution center problem, a mathematical model of the distribution center of the LRTWP (Location and Routing with Time Window Problem) was established. An improved simulated annealing algorithm was used to solve the model, the parameter and selection operator in the algorithm is setted reasonably. Simulations and results indicate that the improved simulated annealing algorithm has better feasibility and validity for solving the LRTWP.

Abstract: The so-called e-commerce refers to the ESD (Electronic System of Distribution) which can be achieved in the areas of enterprises through the modern network and information technology, including the issuance and exchange basic information of the network, enterprises promotion, pre-market advertising, after-sales service and electronic distribution by electronic means, as well as, internal process and the electronic management information system applications of enterprises. In order to accommodate the complex network data of large scale companies, this thesis analyses PMI, strategy and role hierarchical model. On such a basis, the thesis proposes an applicable plan for access control of enterprises information system based on attribute certificate. These new entrants are often backed by advanced technology companies and competitive organizations with funds from Chinese and foreign conglomerates. Therefore, the applications of e-commerce in the field have brought about the information of business operations and internal management, which can provide consumers with a higher quality of services. In this paper, the enterprises information management and organization will be discussed in the e-commerce. Currently the technology of information and network develops rapidly. As a result, e-commerce, e-government and e-office prevail over our society and have become a part of our life. This situation enhances the efficiency of work and changes for the enterprises information management in China.

Abstract: A camera self-calibration algorithm based on the Kruppas equation has been put forward by decomposing the fundamental matrix on the basis of computing the geometrical static moment. The fundamental matrix could be estimated through the normalized 8 points algorithm in which the centroid of the irregular polygon was calculated by computing the geometrical static moment. The five intrinsic parameters of a camera were calculated in accordance with the optimal target function established from the simplified Kruppas equation and the linear equation about the five internal parameters of a camera. The experiment showed that the five intrinsic parameters of a camera could be realized by this method.

Abstract: Wearable computer will give a huge impact on traditional industries, which can effectively overcome the traditional industrial areas in the mobile monitoring, data acquisition, and the difficulties encountered by the large and complex equipment installation, maintenance and breakdown maintenance, special industrial field operations, remote collaboration. This paper is to study the wearable computer applications in the industrial field, and wearable computer design specifications. The model of the hardware and software is designed based on these indicators, and study and design a complete design.

Abstract: Whether charging the electric vehicle is convenient has an important impact on the promotion of electric vehicles, the construction of charging stations should minimize the total cost of charging the electric vehicles. In order to select the optimal building addresses of charging stations, this paper proposed a site selection method based on the Floyd shortest path algorithm. This method uses the analysis of the shortest charging path between the electric car rallying points by shortest path method, and combines the assumption of charging cost and the number of charging stations in order to minimize the total charging distance in the region. Through the example analysis, this method can select one or more optimal construction sites of charging stations in the regional networks quickly and conveniently, so that the minimum total charging distance can be got and the optimal economic benefits can be achieved, too.
