For storing and modeling three-dimensional(3D)topographic objects(***,roads,dykes,and the terrain),tetrahedralizations have been proposed as an alternative to boundary *** in theory they have several advantages,current implementations are either not space efficient or do not store topological relationships(which makes spatial analysis and updating slow,or require the use of an expensive 3D spatial index).We discuss in this paper an alternative data structure for storing tetrahedralizations in a database management system(DBMS).It is based on the idea of storing only the vertices and stars of edges;triangles and tetrahedra are represented *** has been used previously in main memory,but not in a *** describe how to modify it to obtain an efficient implementation in a DBMS,and we describe how it can be used for modeling 3D *** we demonstrate with different real-world examples,the structure is compacter than known alternatives,it permits us to store attributes for any primitives,and has the added benefit of being topological,which permits us to query it *** structure can be easily implemented in most DBMS(we describe our implementation in PostgreSQL),and we present some of the engineering choices we made for the implementation.

多年来 ,许多国家都普遍认识到需要将交通和土地使用规划政策一体化。英国也不例外 :一段时间以来 ,政府的规划指导强调 ,土地使用规划和交通政策需要一体化。本文讨论了实践的情况 ,考察了英国地方当局实施交通和土地使用规划政策一体化的程度。文章勾勒了英国交通和土地使用规划政策一体化的政策环境 ,讨论了实施政策一体化在制度和专业方面面临的阻碍。文章汇集了有关这一主题的最新文献以及参与交通和土地使用规划政策的地方政府官员的观点。本文指出 ,在地方 ,交通和土地使用规划政策的决策在实践中并不总是那么一体化的。

在荷兰,社会(公有)出租的住房的比重占到了35%——是欧盟范围内这一比例最高的国家。这一部门是在1901年住房法确立的公共框架下由独立经营的住房协会所主导的。本文阐述了住房协会在1995年"总收益与收支平衡实施办法"执行前后的历史渊源和发展变化。自从这一办法实施以来,住房协会不再从政府接受实物补贴。但是,它们却变得愈加富有。这一点将会影响住房协会的社会形象。由于结合了社会与市场行为,在坚实的公共框架下运作,并经营高品质多样化的住宅,荷兰的社会住宅可为其他欧盟国家、俄罗斯和中国提供借鉴。
