以南京梅花山为研究对象,以IKNOS,QuickBird等高分辨率遥感数据、数字高程模型为主要信息源,通过遥感图像处理与地理信息系统软件Erdas8.7,ArcGIS9.0提供的可视化功能。对2000年,2004年风景林关学状况进行评价.在研究区域小班... 以南京梅花山为研究对象,以IKNOS,QuickBird等高分辨率遥感数据、数字高程模型为主要信息源,通过遥感图像处理与地理信息系统软件Erdas8.7,ArcGIS9.0提供的可视化功能。对2000年,2004年风景林关学状况进行评价.在研究区域小班界线提取、空间子集生成的基础上,根据不同类型风景林的划分标准和各自关学评价因子,在计算机屏幕上通过目视判读的方式进行风景林类型划分和关学评价因子的提取.评价因子中地形起伏状况可从地形阴影图直接获取,而眺望条件需借助于ArcGis的视域分析功能实现.研究表明:2000~2004年间,梅花山风景林关学质量呈变化不大、总体改善的趋势.针对不同风景林类型,制定了提高风景林关学等级的经营措施,探讨了可视化评价方法存在的问题和未来的研究方向. 展开更多

Quality evaluation is a bottleneck restricting the modernization and internationalization of Chinese materia medica (CMM). Due to characteristics of multi-component, multi-efficacy, multi-target, the existing quality evaluation system still cannot fully meet quality control needs of CMM. Hence, the author put forward “Bio-characteristic profiling related to clinic, BPRC” academic concept, meanwhile, fully take the advantage of analysis method with clinical monitoring superiority or profiling characteristics, build up “BPRC” new technology platform, in order to realize “real-time, dynamic and full-range monitoring” new technologies of CMM quality evaluation system and promote the further development of CMM industry. 展开更多

The aim of this paper is to present the main results arisen from the joint efforts of the public-private partnership in being between CCII (Centro Cultura Innovativa d'Impresa) of University of Salento and Apphia s.r.l.. This paper will focus on the results of the core of the OBSS (on board stability system) module that, starting from the exact 3D geometry of a ship hull, described by a discrete model in a standard format, the distribution of all weights onboard and the data acquired by the system, calculates ship floating conditions (in draught, heel and trim). The proposed approach is based on geometry meshes represented by an universally accepted file format (named OBJ) first developed by Wavefront Technologies. Demonstration of the validity of the results is done by the authors using as hull model a simple rectangular box. 展开更多
