To proceed, in terms of system functionality , database structure , input and output interfaces , system and user interaction methods were designed, proposed framework for tourists tourism management information system , functions and solutions with ASP programming from needs analysis language developed software.vv

Abstract: According to the characteristics of the tea product traceability and monitoring system, the master-slavedatabase architecture is adopted. Based on Amoeba frame, the separation technology of reading and writing isachieved. Experimental results show that the design of master-slave distributed database is correct. And the achievement of separation technology of reading and writing effectively implement a distributed data managementto improve data processing efficiency.

Abstract: with the popularity of electronic commerce, its security problem is more and more attention. As unsafe incidents occurred frequently, people for the security of e-commerce is becoming more and more attention. E-commerce security is a core and the key problem of e-commerce development, the development of efficient and safe electronic commerce management system is very necessary. According to the electronic commerce security architecture, this paper studies and analyzes the network service layer, layer encryption technology, security authentication, transaction protocol layer, potential danger in business system and so on various layers and safety technology, according to the security of the encrypted data and the data transmission performance problems, applying the appropriate encryption algorithm to improve the security and speed of the system.

Abstract: With the constant progress of science and technology and the popularity of computer, the human-computer interaction way, tends to be diversified. From the traditional keyboard, graphical user interface (GUI), tablets of handwritten Chinese characters to the recent hot speech recognition, gesture of somatosensory peripherals. Undoubtedly, the human-computer interaction way trends to be more nature and convenience. Gestures with the characteristics of intuition and naturalness have become an important means of human-computer interaction. It got rid of the bondage of traditional keyboard, mouse and so on, more in line with the habit of human beings, therefore has very broad application prospects. In this paper, gesture recognition is also chosen as the research subject.

Abstract: The existing database marketing system of a Tobacco Company can achieve customer care and communication, and collect customer consumption information effectively.However,with the development of the enterprise, the information data it collects is growing very rapidly, therefore,it becomes increasingly difficult to analyze the data on the basis of existing hardware and software.This paper will solve the problem of serious loads on the system caused by massive data by the way of Hadoop Cloud Computing applied in database marketing system,thus improving execution and analysis speed and effectiveness of the system, reducing the cost of system upgrade.

Abstract: Based on the theories of density interpolation schemes for structural topology optimization,introduced the method of moving asymptotes to the theories of RAMP.With the structural volume as the constraint,the method of moving asymptotes based on the theories of RAMP to solve the problem of minimize structure compliance.The correctness and validity of the method were verified by a case.

Abstract: Homogenization or material distribution method based topology optimization will create final topologies in grey level image and saw tooth jump discontinuity boundaries that are not suitable for direct engineering practice, so it is necessary to extract the topological diagram. And a new topology extraction method for compliant mechanisms is presented. In the fist stage, the grey image is transferred into the black-and white finite element topology optimization results. The threshold value meeting to objective function is obtained so that each element is either empty or solid; in the second stage, the density contour approach is used by redistributing nodal densities to generate the smooth boundaries; in the third stage, Smooth boundaries are represented by parameterized B-spline curves whose control points selected from the viewpoint of stiffness and flexibility constitute the parameters ready to undergo shape optimization; Then shape optimization is executed to improve stress-based local performance, The parameters that present the outer shape of the compliant mechanism are used as design variables; In the final stage, simulations of numerical examples are presented to show the validity of the proposed method.

Abstract: Gaussian processes is a kind of machine learning method developed in recent years and also a promising technology that has been applied both in the regression problem and the classification problem. In this paper, the general principle of regression and classification based on Gaussian process and experimental verification was described. A comparison about accuracy between this method and Support Vector Machine (SVM) is made during the experiments.Finally, it was summarized of the regression and classification of Gaussian process application and future development direction.

Abstract: Sports meeting organization and presentation of the input and output of information, statistics and query it has been the most tedious, complicated and hard work. Therefore, a sports meeting management system based on information technology been developed in today's information age. It sets enrollment management, game management in one, self-realization sports management, intelligence, to improve management efficiency and quality. In this paper, the actual management experience, methods and processes of the university as a research object games, design and develop a manage system suitable college sports ,It enables efficient exchange of information can be participants, spectators and between managers improve the management efficiency of college sports, and to promote the development of sports.

Abstract: Forming process parameters are used for providing reference to forming process and die design, which are achieved from uniaxial tension and simulation tests. The forming characteristics in the as-quenching conditions are different from the annealing and T3 status. Database is involved in any kind of hydraulic stretch forming materials parameters used. Its application scope is broad. The graphics data and attribute data are managed using SQL server relation-database technology, management information system is developed by using Visual Basic. The database is convenient to query, retrieve for relevant personnel .Then it provides reliable basis for sheet metal rubber bladder forming more accurately.
