Abstract: An entropy fuzzy matter-element model is combined, based on the establishment of credit risk evaluation index system of the power listed companies. The model uses entropy weight method to determine the weight of evaluation index, which has strong objectivity. The calculation results show that this model is scientific and practical.

Abstract: Manganese in water has low toxicity. The product will form the yellow stain when the industrial water content is high. There are many ways to monitor it. The determination of trace Manganese in the YangjiaoPu source water by oscillographic polarography is introduced in this paper. The result indicate that the standard deviation of this method is 0.001~0.002 mg/L, the relative standard deviation is 2.3~2.5% and the mark-on recovery ranged from 96.8%～105.8%. At the same time several problems needing attention about experiment process are posed in this paper.

Abstract: The risk assessment is a very important aspect in the process of plant construction and operation. The risk factors of Bio-technology Group, Handan Chenguang protein plant are analyzed in this paper. Meantime propose preventive measures and contingency plans. Thus offer technical assurance for the possible risk of the environment when the project launch smoothly .

Abstract: The resource limitation of mobile commerce systems cause the problem that the existing image processing software based on the centralized computing mode had difficulty in running in mobile commerce systems. This paper gives a solution for the problem by adopting web service-based image processing approach. The solution reduces the resource consumption of mobile commerce systems by distributing image processing tasks to service providers, service registry centers and service requesters. Furthermore, a web service discovery algorithm called WBSD is presented. Service providers adopt the WBSD to provide efficient services and increase image processing speed. Compared with traditional methods of image processing, Web service-based image processing method has the advantages of loose coupling and component oriented and can take full advantage of the computing resources in heterogeneous network. Thus web service-based image processing approach can effectively solve the resource bottle-neck that traditional image processing software had.

Abstract: Luxury consumption in China has seen a rapid development over recent years. From the eyes of luxury suppliers, China is a huge market with the highest potential which is not yet fully opened. Considering the market environment in China and comparing with method in developing the traditional physical stores, suppliers will tend to choose internet direct marketing as means when developing new market, which will be an excellent supplement or even a replacement in this concept. The paper make an introduction of luxury, then analyze the possible problems of internet direct marketing for luxuries under existing domestic environment and bring forward the countermeasure to deal with them. The paper is helpful for the development of luxury market in China. With the situation in China fully considered, most of the conclusions are useful and practical.

Abstract: With rapid development of search engine users, the auto bidding for search engine keywords is stealthily rising and such kind of service is now essentially being conducted on the majority of existing search engines. For merchants, users and even the search engine service suppliers, auto bidding is of many advantages, which is also thought it has brought forth serious phenomenon of bad faith in terms of such kind of similar search websites, leading to a crisis of confidence. This text is intended to give it a full analysis on the various problems of bad faith resulted from the auto bidding for search engine keywords. And it is in consideration of the huge controlling forcing and social influence of the search engines, there lies a great need in strengthening the closer government supervision. While guaranteeing a healthy and orderly development of search engine, our purpose is to render back an honest and clean searching environment of internet information to the public.

Abstract: As the principal body of technology innovation and the core value-creator, the high performance of knowledgeable employees in knowledge-based enterprises is the foundation of the enterprise improvement. While how to appraise and raise their performance is a difficult problem, the paper studies performance evaluation of knowledgeable employees in knowledge-based enterprises based on knowledge-based enterprises and knowledgeable employees' own characteristics, aim to set up a performance evaluation process to identify, appraise and improve the employee performance effectively. The paper also proposes several advices to appraise the knowledgeable employees.

Abstract: By analyzing the structure of PDF files as well as the characteristics of CORBA technology and taking the information dump from PDF files to SQL Server as an example, the paper illustrates the achievement of integrated system of E-book resources. The paper shows the system framework and process design. With a view to the integration of electronic resources, this paper can play a reference role to the integration of E-books resources.

Abstract: In the paper we adopted CDIO as the guiding ideology, analyzed the shortcomings in laboratory and equipment management and the relevant causes, and then proposed an effective solution which combined with laboratory and equipment management-related standards in CDIO and current actual situation of experiment teaching and the protruding problems in laboratory management.

Abstract: Subminiature fixed-wing Unmanned Aerial Vehicles (SUAVs) present enormous potential. In order to develop a robotic SUAV with significant levels of autonomy, a portable ground control and test station (GCTS) is studied and developed. The requirements of GCTS are analyzed and the overview of GCTS is given firstly. Then the main operation modes of digital data link module are detailed. As the core of the portable GCTS, a set of software tools, including embedded map and trajectory visualization, 3-dimention attitude viewer, avionics panel, plotting utility, mission and control configuring, flight data and mission video storage and playback, etc., are researched and developed. The flight experiments application validate that the portable GCTS satisfy most of the requirements, and mitigates the difficulties and cost of development of the robotic SUAV remarkably.
