多光谱成像仪几何特征标定技术研究

多光谱成像仪具有同目标多谱段信息获取的特点,因此在空间遥感领域占据很重要的位置。由于成像仪光学系统不可避免的存在几何畸变问题,会对获取地面目标信息的精度造成很大的影响,因此对于多光谱成像仪进行几何特征标定对于提升成像仪成像质量的有很大的作用。本文中应用标准网格板、自准直仪和高精度二维转台组合的几何特征标定方法,此方法具有测量原理简单、实验直观、标定结果可靠性高等特点。多次标定结果表明：主点标定精度优于5.2 μm,主距标定精度优于0.02 mm。满足实验要求。     

The Presence of the Weather

Modern architecture has dedicated much of its discourse to crystal-ball gazing – dwelling on the visionary and the speculative. Conversely, Kevin Nute , Professor of Architecture at the University of Oregon, puts the case for the present over the future and the past. To enhance experiences of the present, he describes how architects can harness the effects of changing temporal and weather conditions – sun and shadow, wind and rain. Design can heighten the sensory stimuli these conditions generate, keeping us ‘in the moment’ while still enjoying the comfort of being indoors.     

以廊为主题的地域建筑设计实践

廊作为建筑类型和符号,在中国当代建筑创作实践中被广泛运用。将相关设计思路归纳为三种倾向,继而分析汤桦的建筑设计作品中线型元素的应用,归纳为以类型学方法展现廊在建筑、城市双重尺度上表现力的设计倾向。在对这些设计倾向进行研究的基础上,将廊作为明确符号意义的建筑类型,进行了一系列建筑设计实践,进而提出以廊为主题的地域建筑设计思路,并以相关的四个作品作为例证。     

Norfolk Park Green Homes,Sheffield

In a neighbourhood of Sheffield that was once dominated by tower blocks, Matthew Lloyd Architects has created colourful timber-clad homes that resemble a community. David Littlefield describes how a determined architect and client, despite local scepticism, have been able to provide housing that is not only spacious, generous in size and sustainable, but also comparatively cheap.

崀山风景名胜区管理设施设计探索

风景名胜区景区入口管理设施具有典型的风景建筑的特征,代表了景区的形象和特征,是风景区总入口和景区之间的过渡与衔接点,对风景区的整体形象和游客的游览感受有着十分重要的作用。该文以崀山风景名胜区五个景区入口服务设施设计为例,对景区入口管理设施的设计方法、设计中需要考虑和施工中可能出现的问题做出总结,为风景建筑的设计者提供有价值的实践经验,以利于更好地开展风景区的建设。     

The Open City and the e[ad] School of Architecture and Design

Located in Ritoque on central Chile's Pacific coast, Open City is a unique community established in the 1970s by faculty members from the nearby e[ad] school of architecture at the Pontifical Catholic University of Valparaíso. Here Professor David Jolly Monge , a founding member of the Open City, and Guest-Editors Christian Hermansen Cordua and Michael Hensel describe how the construction of structures on the site offer the collective community and students alike ongoing opportunities for ‘thinking, research and experimentation’.

明朗擦洗砂在酯硬化水玻璃自硬砂上的试验与应用

研究了明朗擦洗砂作为酯硬化水玻璃自硬砂的原沙时,水玻璃加入量、酯的加入量、原沙含量等因素、对酯硬化水玻璃砂的硬化速度,强度及残留强度的影响。并在小型铸钢件上进行代替树脂砂生产试验,取得了良好的效果。     

郎枣轻微损伤可见/近红外光谱分波段动态判别研究

为了实现轻微损伤郎枣的快速无损检测,以完好和轻微损伤郎枣为研究对象,动态采集其可见/近红外光谱数据。依据光谱波段定义将采集的光谱数据分为可见光(Vis)、短波近红外(SW-NIR)、长波近红外(LW-NIR)、可见/短波近红外(Vis/SW-NIR)、近红外(NIR)和可见/近红外(Vis/NIR)等6个波段,分别选取各波段最佳预处理方法。采用连续投影法(SPA)和主成分分析法(PCA)分别对各波段光谱数据降维,以全波长、SPA提取的特征波长和PCA提取的主成分作为输入,分别建立偏最小二乘回归法(PLSR)和最小二乘支持向量机(LS-SVM)模型,通过比较预测集的判别准确率,确定最佳建模方法。结果表明,PLSR模型优于LS-SVM模型,SW-NIR波段较其余5个波段有更好的判别能力,所建SW-NIR-SNV-SPA-PLSR模型判别准确率为93.3%,为最佳模型。本实验为轻微损伤郎枣的快速无损检测和相关仪器的开发提供了理论基础。
