Using load balancing mechanism, multi application servers can cooperate in the distributed GIS to realize task scheduling and load assigning. And in this way it improves the service ability of the distributed system. 通过负载平衡机制,可以实现分布式GIS中多个应用服务器协同工作,完成GIS应用服务的任务调度和负载分配,提高整个分布式GIS的服务能力。
Multi application platform in a business, the user only once the identity authentication in an application, you can free access to all the mutual trust and application system. 通过单点登录技术,在一个业务相关的多应用平台中,用户只在某个应用中进行一次身份认证,就可以自由访问所有相互信任的应用系统。
The paper is based on CPU soft nucleus Nios of Altera Company, Quartus ⅱ software and Sopc Builder. It introduces a method to develop a high precise signal source, that is the multi application of DDS and dynamic dividing of frequency. 以ALTERA公司的CPU软核Nios为基础,利用QuartusⅡ软件和SOPCBuilder,采用两级DDS和动态分频法,提高了信号源的精度。
