Objects after Image

For 12 years, the Koshirakura Landscape Workshop has been an annual summer event. Located in a beautiful and remote region of Japan, it encourages a small group of architecture students to respond to the setting by creating projects that read, represent and spatially reconfigure the landscape into new constructions. Shin Egashira reveals how, over time, these constructions in turn act as a continuous form of documentation and reflection. Copyright © 2008 John Wiley & Sons, Ltd.

The Global Architectural Influences on London

London today has become ‘a laboratory and testing ground’ for neoliberal capitalism, attracting investment from the Middle East, Russia, India, the Far East and Australasia as well as the US. Murray Fraser describes the urban impact of economic globalisation in the capital, while exploring ways that it might potentially be countered. Copyright © 2012 John Wiley & Sons, Ltd.     

Material Behaviour: Embedding Physical Properties in Computational Design Processes

Material behaviour computes form. In the physical world, material form is always inseparably connected to internal constraints and external forces; in the virtual space of digital design, though, form and force are usually treated as separate entities – divided into processes of geometric form generation and subsequent engineering simulation. Using the example of the interdisciplinary ICD/ITKE Research Pavilion, constructed at the University of Stuttgart in 2010, Moritz Fleischmann, Jan Knippers, Julian Lienhard, Achim Menges and Simon Schleicher explain how feedback between computational design, advanced simulation and robotic fabrication expands the design space towards previously unexplored architectural possibilities.

集聚纺车间地沟均匀吸风设计方法探讨

探讨集聚纺车间地沟均匀吸风设计方法。介绍了地沟均匀吸风的设计原理和实现均匀吸风的措施;分析了变风量系统对均匀吸风性能的影响;介绍了变风量均匀吸风系统的设计;计算分析表明:回风沟道应采用变截面分段设计法,吸风口采用条缝型形高速自适应风口,吸风口面积之和与沟道截面积之比不大于0.4,前后吸口的吸风不均匀程度可以控制在15%以内。认为:采用支沟道变截面分段设计能较好地控制吸风的均匀性,可以保证集聚纺车间气流均匀稳定。     

基于同步数据的电力系统不同保护方式下故障在线定位

电力系统保护机制出现故障可导致保护装置拒动或者误动,影响系统的安全稳定运行。大数据处理技术在电力系统中逐渐应用使得电力系统保护可以实时在线分析,因此可在一定程度上避免级联事故。文中提出了一种基于大数据同步信息的保护在线分析机制。首先选取大数据量测节点,并对电压和电流量测数据进行处理。为了分析保护装置的动作情况,依据网络拓扑结构得到所选节点的同步数据。然后利用同步数据计算得到距离保护、方向保护和过电流保护下的指标,并构建了以该指标为变量的继电保护装置故障识别函数,经过计算故障下的函数值,以确定继电保护动作矫正方案。最后在IEEE39节点系统中进行了仿真分析。     

Astronauts Orbiting on Their Stomachs: The Needs to Design for the Consumption and Production of Food in Space

The sustainable and convivial habitation of Space requires the provision of a ready food supply that does not have to be transported from Earth. Architect and space researcher Sandra Häuplik-Meusburger highlights how important it is that Space Architecture fully accommodates and abets the consumption and production of food.
