Abstract: The system uses the MCU to complete the functions such as regularly collecting, computing, error handling, storage, data transmission control, and so on, for the parameters required measurement. The system consists of four components: sensor and modulation circuit part, A/D transformation and send part, optical fiber coupling part and the receiver display part. The system has the following characteristics: The encoder is used to encode and send the digital signal of the measured parameters. Through the optical fiber coupling, this system displays the corresponding measurement parameters after decoding by the decoder. System circuit design is simple, easy debugging, reliable of information transmission, high precision of data transmission, particularly good anti-interference, no need of great sending power. It can be applied to a strong electric field or strong magnetic interference occasions at a distance from tens of meters to hundreds of meters.

Abstract: In order to provide one-stop service of professional title assessment for the college staff, the business process based on SOA integrating personal qualification, automatic generation of vocational assessment materials, quantification of evaluation index, online expert assessment and vocational assessment information release is presented. Especially, the business process reengineering and business service lay-out is designed, heterogeneous distributed data sharing and exchange of the problem is solved, and the original isolation of the information system is integrated as a whole. The professional title assessment system implemented in China Three Gorges University digital campus is setup, which increased the objectivity, scientific and transparency of professional title assessment and improved the working efficiency.

Abstract: A new blood vessel robot is designed, which has two fragellas and cylinder, its thrust force and torque equations are given. Through CFD method simulated the outside flow field characteristics of robot, lots of flow parameters could be obtained, these data help us to optimize the outline of robot. From the computation results, the wall shear stress (WSS) should be influent by flow status (steady flow or unsteady flow) and robot outline, along with velocity decreases, the WSS declines, and the WSS, pressure, velocity would vary obviously as the robot outline changes.

Abstract: The number of base station location impact the network quality of service. A new method is proposed based on immune genetic algorithm for site selection. The mathematical model of multi-objective optimization problem for base station selection and the realization of the process were given. The use of antibody concentration selection ensures the diversity of the antibody and avoiding the premature convergence, and the use of memory cells to store Pareto optimal solution of each generation. A exclusion algorithm of neighboring memory cells on the updating and deleting to ensure that the Pareto optimal solution set of the distribution. The experiments results show that the algorithm can effectively find a number of possible base station and provide a solution for the practical engineering application.

Abstract: Countering the inventory management problem of manufacturing enterprise, according to the optimal control theory, considering the numbers of products as control variables and the stocks as the state variables, this essay establishes systemic real-time dynamic model, gives the objective function, and makes use of dynamic programming method to solve the optimal control and obtains the optimal inventory, which provides a theoretical foundation for the production and inventory management of manufacturing enterprise.

Abstract: With the sharp increase of data amount in modern computing process, it needs more powerful general computing ability to process and compute data. Web Services--based Distributed Universal Computing Platform (WSDCP) provides an inexpensive solution for large-scale computing tasks in a loosely coupled manner with high flexibility and node autonomy. System adopts Web Services, XML as technical support, through installation of intelligent probe on nodes to real-time collect the situation of node, and the disequilibrium task allocation and dynamical task regulation can improve system reliability. WSDCP system takes green computing concept as guiding concept, and takes advantage of idle CPU resources on the Internet, which have positive significant for establishing resource-conserving society.

Abstract: Quality Function Deployment is a quality assurance method that user-driven and meeting customer demands mostly in process of product development and design. It is emphasized to ensure requirements and measures of quality. And Fuzzy Analytic Hierarchy Process considered vague language of judgment matrix can overcome the subjectivism and one-sidedness considered of Analytic Hierarchy Process. Approach of Fuzzy Analytic Hierarchy Process is applied to model Quality Function Deployment in an example of small ERP software development in the study.

Abstract: An outline of marketing decision supporting date warehouse system based on the existing databases is proposed. The application of data warehouse technique and multi-agent systems to modern marketing decision support system may assist supervisors of enterprise to make an analysis of strategic decision and to improve the competitive power of the enterprise. Finally, the developing tools and the implementation of the Web-enabled data warehouse were discussed.

Abstract: This paper discussed library under the network environment of the movement and the development. Digital Library will be understood as a new information environment is a more broad definition. The mandate of the Digital Library will focus on building a network of resources and resource organizations, the number of objects a unique identifier, metadata interoperability, digital resources, such as opening up links.

Abstract: In order to illustrate and analyze the different features between two-stage advanced botnet propagation modeling and multi time zones modeling, an improved honeypot-aware advanced botnet propagation model using multi time zones is proposed. The model is based on two-stage reconnaissance process and firstly induced the time zones factor, then the diurnal properties of regional variations in online vulnerable populations in multi-time zones is creatively given. Also the novel impact of recovery rate is concerned by simulation.
