Abstract: The load balancing method based on the Linux server cluster is proposed in large-website construction. The load balancing of server cluster is achieved by SSH framework, Oracle database and Ajax technologies. The load balancing of server cluster method can’t only improve performance, scalability, availability of system and reduce the execution time of multi-tasking but also eliminates network bottlenecks and improve the flexibility and reliability of the network. In order to verify the validity of the algorithm, large number of experimental data is used in the experiment. We propose a method of load balancing algorithm is compared with the traditional non-load-balancing algorithm for CPU utilization and system response time in the experiments. The experimental results show that the load balancing technology can reduce system response time and CPU utilization of server.

Abstract: The magnetohydrodynamic (MHD) flow control techniques for inlet based on “AJAX” vehicle concept have attracted many researchers’ attention for its potential wide applications in the supersonic flights or the hypersonic ones. In this paper, a preliminary discussion for basic problems that are ionization and magnetic field in the MHD applications is presented. And three major MHD techniques for enhancing inlet aerodynamic performance and operability, which are large scale flow control for enlarging flight scope in Mach/angle-of-attack, near surface flow control for shock wave/boundary layer interaction and leading edge heating-transfer control for enormous thermal load on leading edge of the compression ramp, are briefly explained and reviewed.

Abstract: It researched key technology based on ajax of svg in feeder data analysis system, for the requirement of complicated circuit quick analysis and high efficiency in aviation arming ensure domain, combined with S1000D specification for interactive electronic technical manuals and data requirements of creative thinking, proposed feeder S1000D data modules and svg technology dynamic publishing model,and the application of research results, case study results show that: The design can be automatically and quickly analyze circuit through the auxiliary equipment, leads the list of inter-path, achieve troubleshooting.

Abstract: As Web2.0 rapidly develops, B/S structure is increasingly used in applications. Many applications require higher conditions in being real-time. However, due to the limit of applying in communication modes of the B/S structure [1], B/S structure can’t meet the requirement. To solve the problem, solutions have emerged incessantly. This thesis first analyzes the reason of the problem, and tries to review existing solutions. Then performance, advantages and disadvantages are analyzed and summarized subsequently. This thesis mainly introduces the WebSocket protocol of HTML5 standard, and also compares it with polling’s performance. Finally, this thesis discusses the choices of push technology in concrete applications.

Abstract: With the more and more expanded city and the heavier remote sensing image production, update, management, building the modern Remote Sensing Image Publication System is placed in the forefront for providing the good services. The paper discussed the NET system of Remote Sensing Image Publication System based on SuperMap IS.NET, and so more, the core contents including data-model, system-structure, system-aim, and key technology about the system are introduced in this paper.

Abstract: In the use of Ajax technology on web pages, it is needed to execute client-side Javascript code to present dynamic information. This will result in that a lot of useful data cannot be retrieved with search engine. This paper will introduce a method based on calling browser API and, add the preprocessing stage and put forward effective element specification before trigger the Ajax page events. Besides, several experiments are introduced to testify it’s feasibility and effectiveness.

Abstract: Now the popular Struts+Spring+Hibernate framework provides a weak coupling, easily containable, lightweight J2EE software development model which helps to build high-quality Web applications. Through researching of SSH framework and ExtJS framework based on AJAX technology, an integration framework is designed, which is based on ExtJS+SSH ,and can be used to build a flexible, easily extended and maintainable multi-tier Web application platforms. In this paper, a teaching resource management network platform is introduced, which is based on the integration framework. Experimental results show that business operations, the database, and display will be divided completely by using this integration framework based on ExtJS and SSH, in order to achieve a system of weak coupling and high level of maintenance.

Abstract: In this paper, using UML modeling tool (Rational Rose) conducted a needs analysis and modeling system, and on this basis, we design the interface module functions, system architecture and database. The paper finally designed and realized the system based on the.NET platform and Ajax technology. The system uses SQL Server as the background data management system, and in the end using ADO.NET technology to realize data access. According to the actual scientific research management, system design includes integrated office, scientific research institutions, scientific research personnel, research projects and other subsystems. the majority of teachers and the laboratory research team can within the prescribed time limit, in any location by logging into the science and Technology Department of scientific research project management webpage query declaration, provides great convenience for research teachers.

Abstract: In the experiment of Neutral Beam Injection (NBI), Experimental Data Publishing Software (EDPS) is developed to get experimental data monitored remotely. Adopting B/S module, EDPS publishes information, such as experimental configurations and results on the Internet dynamically. The design and implementation of how EDPS uses the present information source in NBI Control System (NBICS), the procedure EDPS handles the requests from clients and displays the information on web pages are introduced in this paper.

Abstract: This paper analyzes the present situation of intelligent transportation industry in China and proposes a solution based on web map compatible interface which is aimed at satisfying the various requirements of the vehicle monitoring system on map. Firstly the technical feasibility of the solution is analyzed and 36 interface methods are listed. Then design principles and key techniques of vehicle monitoring and tracking, historical trajectory playback, regional function and monitoring are provided. Finally the development environment of the system and the screenshot of running results are presented. This system has already passed the platform compliance testing of the Department of Transportation and has achieved good results in management benefit in several enterprises.
