基于本体库的第五级IETM研究 总被引:2,自引:0,他引:2
技术手册TM(Technical Manual)是军事装备、民用产品使用和维修的保障要素之一,技术手册数字化是装备保障数字化的发展方向。按国内外军用电子技术手册的分级标准,第五级交互式电子技术手册IETM(Interaetive Eleetronic Technieal Manual)是当前开发的最先进级别,它是在第四级基础上进行多功能、多应用的整合。本文以本体作为技术手册中知识表示的手段,构建领域本体库,解决了IETM不同用户和应用程序之间概念共享和互操作问题,也为IETM的语义WEB发布准备了必要的本体词汇。 相似文献

美国国防部正在加紧对纸型技术手册(TM)进行数字化处理,大部分纸型技术手册经数字化处理后直接拷贝到磁盘,另有一小部分升级为电子技术手册(TEM)或交互式电子技术手册(IETM)。然而,没有一种简单易行的方法可被用来以较低的费用来将纸型技术手册转化成各种类别升级产品。先进技术办公室、美军测试/测量/诊断设备专门小组、美军导弹指挥中心已经开发出了转化技术/工具,并开发了转化程序,从而可以实现以下这些目标:以较低的费用开发功能强大且用户友好的ETM/IETM。本文将提供一些指南来帮助ETM/IETM开发者实现这些目标。 相似文献

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form. 相似文献

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues. 相似文献
