Abstract: Based on the original CAV formula definition given by the electric power research institute in the United States, the continuous integral formula is discretized so that it can be better applicable to the actual application requirements, and also the shaded area calculation method necessary in the process of calculation is further proposed. Finally, this algorithm is implemented with LAVIEW program, and also the simulation data and the CAV calculation result of the real Lushan earthquake acceleration data were given so that the algorithm was fully validated, and also a solid foundation was further laid for the deeper CAV-related parameter study.

Abstract: Cloud computing is a high-tech developed rapidly relatively in recent years, you can take advantage of cloud computing to share the storage space and computing power on the network, then allocate and use it according to the users demands to prevent the waste of resources but to get fully utilized. The data generated from library is also growing rapidly, so that universities need a management system which can manage a large-scale data to manage its data library. Generation of cloud computing is bound to lead to the change of library management system structure, there will be more and more university libraries try to use cloud computing to improve library network information management and service levels, and to reduce management and service costs. And cloud computing university library to solve the problem at this stage has become an inevitable trend, but universities still need to constantly research and practice before the trial.

Abstract: The modern logistics as the product of the modern scientific and technological progress is to promote the logistics industry toward efficient, fast, low-cost distribution system was further extended. Computers in logistics information management, providing a broad space for development, Article by describing the role of computer technology in the logistics, indicating that the two are interdependent and mutual restraint and mutual development of the relationship.

Abstract: With the acceleration of process of modernization as well as continuous development of computer network technology, the Internet application field and category are expanded. As the Internet has the characteristics of richness, high update speed and innovation, it makes people's daily life more convenient, enriches people's material and cultural life and creates a free and open social environment. However, the network is a double-edged sword that brings people both convenience and many security problems, so it is an important issue to improve network environment. This paper combines the author's work experience to analyze the security problems existing in the computer network at present, and explores specific emergency response technology to solve these problems so as to provide fellows or everybody some theoretical suggestions and basis.

Abstract: The system uses B / S mode and ASP as the web-based support and connects with the SQL Server 2005 database, which realizes the automatic and manual assessment of Photoshop course exam management operations. At the same time, it will be able to generate paper reference to test the difficulty levels of papers.

Abstract: With the development of the science and technology of the computer application, the maintenance management and the security of the computers is an important problem. In this paper the author presents his own opinions on these issues. Therefore, the maintenance management of the computer local area network is very important to guarantee the security and stability of the network and to the use of the cyber sources to a maximum.

Abstract: Based on the situation that the statistic of the missile facilities stability was small, and the conventional big example preview method was no longer of use. So, this article used the gray GM (1, 1) model to preview a facilitys stability .The gray GM (1, 1) model doesnt need a large number of example statistics, and it is also accurate, so this model solved the problem in the analyze and preview of the stability of the missiles electronic facility system, and it has possibility to imply to engineering use.

Abstract: Image interpolation is widely studied and used in digital image processing. In this paper, a method of image magnification according to the properties of fractal interpolation and wavelet transformation are presented. We focus the development of edge forming methods to be applied as a post process of standard image zooming methods for grayscale images, with the hope of retaining edges. Experiments make sure it valid.

Abstract: The construction of the computer network experimental platform can effectively solve the existing problems in the computer network teaching, and has the vital significance for promoting the quality education, and improving the students' practical skills. This article mainly discusses the construction of the open experimental platform of the computer network laboratory of the Shandong University, mainly introduces the software and hardware resources of the open experimental platform, and the teaching contents and teaching methods of the open experiment, and sums up the teaching effect of the open experimental platform.

Abstract: Service-oriented architecture (SOA) is a design idea under which we can cover all aspects of the business service in life cycle including the creation and usage of the service. SOA also provides IT infrastructure. It can make the different services exchange data or work is a business process. Implementing the objectives can completely cross operating system platform and cross programming language platform. The objective of the paper is to propose a security service agent based on SOA. The service agent not only can protect the information exchange of network services, but also can realize on different development platforms.
