The studies mentioned above show that the system of structural damage identification based on bp has acquired relatively high accuracy and rapid convergence . meanwhile , the remote intelligent diagnose model based on client as scientific computing center can solve the problem in some extents 上述内容的研究表明:基于java的以客户端为计算中心的网络模型在一定程度上有效解决了远程智能识别所面临的一些问题。
Nowadays , the human society has been coming into a network - computing centered informationera , in which information sharing in great area and distributed transaction is becoming the urgent require of computer application . more and more applications want to access data in different network notes and different database . so multidatabase which can solve the interoperation of heterogeneous database problem is becoming a research hotspot in database area 目前,人类已进入以网络为中心的信息时代,大范围内的信息共享与分布式事务成为计算机应用的迫切要求,越来越多的应用要存取分布在不同网络结点上的、不同种类的数据管理系统中的数据,因此,解决异构数据库互操作问题的多库系统成为目前数据库领域的一个研究热点。
In this thesis , the main studies include : ( 1 ) discussing the advantages of several network models , and finding one which is suitable for large scale science computing ; ( 2 ) the methods and process of establishing the identification system model are demonstrated . and the structural damage identification methods based on bp network for unilateral damage plates and multiple beams are demonstrated ; ( 3 ) based on the b / s model which sets client as computing center , a remote intelligent diagnostic system is developed by java 论文的主要研究内容包括: ( 1 )从现阶段的网络模型出发,探讨了各种网络模型的优缺点,从而改进得出一种适合于大规模科学计算的网络模型? ? “胖客户”服务器模型; ( 2 )讨论了利用神经网络建立结构损伤智能识别系统求解结构损伤识别反问题的思路、方法和步骤,并在此基础上论述了利用基于bp神经网络的结构损伤识别系统对单处、多处损伤结构进行辨识的方法; ( 3 )在以客户端为计算中心的b s模式下,并利用java语言设计实现了结构损伤远程智能识别系统。
Basing herself on the analysis made , the authoress concludes that the task confronting enterprises is to perfect the financial management system , to reasonably share the costs by working out the network basic unit cost driving factors and establish a cost computing center , for the sake of providing development strategies for enterprises 本研究的结论是:完善财务管理体系,合理地寻找产生基本网络单元成本驱动因子来分摊成本费用,建立成本测算中心,为企业的发展提供决策依据。
