Then the paper demonstrates the process to system modeling , analysis and design making use of object - oriented technology and uml , describes and analyses especially expression result to the user ' s needs and system model of uml view . the systematic model to consistency of the user ' s needs model is proved , and the superiority of using object - oriented thought is announced in the software researches and develops . the paper has put forward system ensemble frame mode relying mainly on b / s structure and complemented of c / s structure , and discussed the superiority of choosing java as the programming language and oracle database as stores for the data ; finally , the paper describes the implementation and running situation of ammis based on web , and summarizes the relevant technology and question in the development course of application system 然后,论文论述了运用面向对象技术、 uml统一建模语言进行系统建模、分析和设计的过程,重点描述、分析了使用uml视图对用户需求和系统模型的表达结果,论证了系统模型与用户需求模型的一致性,揭示了面向对象思想在软件研发过程中应用的优越性,提出了以b s结构为主、 c s结构为辅的系统总体结构模式,讨论了选择java为编程语言、 oracle数据库为数据存储的优越性;最后,描述了基于web的飞机维修管理信息系统的实施运行情况,并对应用系统开发过程中相关技术和问题进行总结,对系统待改进之处进行了分析,对飞机维修企业信息化进行了展望。
Instead of fix grids , adaptive grids derived from the pixel projection histograms are employed . the proposed system ensembles multiple classifiers based on boosting algorithm . this integrated classifier works in a similar way to the serial integration mode in the training stage , and to the parallel integration mode in the classification stage 实验基础上,本文从全局特征集、纹理特征集中选取分类能力强的特征分量集;并改进网格的选取方案,采用基于像素投影直方图的自适应网格划分,以处理用户签名的多变性。
