加利福尼亚州的商业景观与购物环境

自20世纪中期第个郊区购物中心兴起之后．北美的商业景观设计也开始逐渐走向成熟。当时的创新理念是打造一个可控制的、无机动车和犯罪行为、室外环境良好的安全购物形式。规模较小的零售点通常会设置在大型购物中心的两端,以吸引购物者。     

An Application of Wavelets in Tomography

A method of tomographic inversion using wavelets is described which relies on the “diagonalization” property of wavelets for the derivative of the Hilber transform. Error bounds are given for reconstruction using the technique and an optimal wavelet which minimizes the error is presented. The method is well suited for inversion of from local data.     

基于数据融合的居民区建筑物重建方法研究

针对美国新奥尔良地区稀疏的LiDAR （Light Detecting and Ranging）点云数据,提出了一种基于LiDAR数据和卫星图像进行融合的居民区建筑物重建方法.该方法利用LiDAR数据点集的边界来定位卫星图像上的感兴趣区域,利用从感兴趣区域中提取的关键提示线来实现屋顶的分割,从而得到属于每个建筑物的屋顶点.然后,基于三角面片的法向量方向信息对其进行聚类,根据法向量之间的关系进行屋顶类型识别,从而实现居民区建筑物的重建.实验表明,该方法在进行居民区建筑物重建时,能达到较高的重建率,且重建所需时间合理,能够满足虚拟现实系统的需要.     

Modern Management's Role in the Demise of Sustainable Society

This paper examines the development of modern strategic management and portrays it as a major problem-causer in modern society, rather than a problem-solver. Frederick Taylor's philosophy and practice of scientific management is alive and well, and stronger than ever, in the final decade of the 20th century. Although scientific management is a vital underpinning to strategic development in a highly competitive, productivity-conscious, organizational world, its intense, single-minded and tunnelvisioned application raises the paradox of it being at one and the same time, “saint and sinner”. Its “saint” role is that of an economic productivity enhancing, competitive capability bestower. Its “sinner” role arises because of the adverse, and potentially dangerous impact it has on rank and file personnels’commitment to, or acceptance of, the way things are in organizations and society. The paper is intended to give an airing to significant problems which are emerging in a practical and theoretical managerial world which seems otherwise to be blindly, and extremely, embracing scientific management as the rightfully dominant paradigm for modern day management strategy. It suggests tha nature of changes which might need to be made to mainstream management paradigms. The challenge is to create a society based, at least in part, on cultural values of opposite dimensions to those which underpin scientific management.
