世界城市发展的大生态观与制度制衡

一、生态足迹视野下的四大城市发展弊端加拿大不列颠哥伦比亚大学社区与区域规划学院教授WilliamRees(威廉姆?里斯)2012年3月7日在纽卡斯尔大学建筑规划景观学院发表演讲,提出了"可持续性的障碍是什么?为什么我们如梦游一般走入全球生态危机之中?"的设问。他从生态足迹分析角度,指出了现代城市     

Synthesis of neural tree models by improved breeder genetic programming

Neural tree model has been successfully applied to solving a variety of interesting problems. In most previous studies, optimization of the neural tree model was divided into two steps: first structure optimization, then parameter optimization. One major problem in the evolution of structure without parameter information was noisy fitness evaluation. In this paper, an improved breeder genetic programming algorithm is proposed to the synthesis of neural tree model. The effectiveness and performance of the method are evaluated on time series prediction problems and compared with those of related methods. Simulation results show that the proposed algorithm is a potential method with better performance and effectiveness.     

Accurate mirror-based camera pose estimation with explicit geometric meanings

An accurate closed form solution is proposed to estimate camera pose by several mirrored reference object images acquired via a planar mirror under different unknown poses. Compared with state-of-the-art methods, our method is more accurate when there are more than three images and has explicit geometric meanings. This method also properly handles cases in which some of the mirror poses are parallel. The central idea is to minimize an error metric based on all reflections of rotation, which enables the camera rotation to be estimated directly by SVD of sum of mirrored camera rotations. After that, the camera translation is computed by solving a large system of linear equations to minimize object space collinearity error. Both synthesized data and real data experiments show the advantages of our approach.     

论汉学家周蕾对老舍《恋》的双向阐发

美国汉学家周蕾运用本雅明关于收藏者的理论解读老舍短篇小说《恋》,并通过对两者的互文性解读,展开对以下命题的剖析和论述:恋物的本质,《恋》的人物特征、心理冲突,老舍和本雅明对于"物"之思的异同,忠诚的命题及其生发出的取舍之精神实质、儒家传统道德观念与爱国主义等。她为中西比较文学的双向阐释在现实语境中如何操作提供了一个创造性范例。     

城市规划专业留杭毕业生住房情况调查及分析——以浙江科技学院为例

随着中国城市化的快速推进和房价的日益飙升,大学毕业生在刚毕业几年间的住房问题显得越来越突出。现以浙江科技学院近六年城市规划专业本科毕业生为调查对象,结合多种调研方法的综合运用,通过对其居住足迹的跟踪调查,剖析大学毕业生的住房现状和住房困难问题,探讨公共租赁房这一保障性住房的准入机制及理想的区位分布等议题。     

泥金漆画与松田权六

中国是个文明古国 ,国人都知道在天然生漆的髹物上敷以金银粉末概称为泥金漆画。这一宝贵的技艺 ,于唐代流传到邻邦日本。日本名之为“莳绘”。泥金漆画 ,是在髹好的器物上先用漆绘好图样 ,待漆末干燥时撒上金 (或银 )粉 ,然后又在上面髹以薄漆 ,漆膜实干后用木炭磨平 ,使之泽光如镜。日本的《竹取物语》记载 ,泥金漆画不仅用之装饰家具漆器 ,而且在屋舍的墙壁上也髹以漆 ,绘以泥金画。这一技法 ,一直流传到近代 ,始终未衰颓过。要说日本的科学较先进 ,取而代之的事是极容易的。但是 ,这个国家很重视传统泥金漆画的保护与流传。不像我们中国…     

对应用投资项目财务评价指标的探讨

投资项目财务效果评价指标，按决策目的可分为绝对效果评价指标和相对效果评价指标两大类；按是否考虑资金时间价值可分为静态评价指标和动态评价指标两大类。本文将按后一种分类对项目评价中使用的各种指标的应用作以下的探讨。
