建筑(建成环境)更新、再利用已经成为当代建筑行业十分重要和普遍的工作。从新建到再利用、从保护到活化的转变对当下建筑教育提出了新的要求,传统建筑教育中建筑史和建筑设计相关课程所面临的挑战尤为严峻。荷兰代尔夫特理工大学建筑与建成环境学院通过改革史学课程、将遗产价值导向置入建筑设计选修课等方式进行探索,一方面以设计教育为史学课程教学目的;另一方面以遗产价值评估作为设计决策的指导和评判标准,实现史学理论教育与设计教育的融合,培养学生在宏观历史、社会文化背景中完成设计/规划的能力。这一探索和所取得的经验,为中国建筑教育改革带来新的思路。  相似文献

Valentina Croci describes how Dutch artist Daan Roosegaarde's Sustainable Dance Floor (SDF) provides the centrepiece for an eco-club in Rotterdam that builds low energy consumption into the attraction. The square dance floor uses ‘mechatronic’ sensors to convert kinetic movement into electricity when people dance. Movement is not only part of the thrill, but is literally electrifying.

If a new stringency with economic and material resources is to become a new way of life, how should austerity be recast as a positive force rather than a negative imposition? Daliana Suryawinata and Winy Maas look at definitions of austerity and describes the Austeria project at The Why Factory at Delft University of Technology (TU Delft) that looked at new models for combating excessive consumption, such as the ‘Zen road to affluence’.  相似文献

An Historic Overview of the Development of Fibre Metal Laminates   总被引:1,自引:0,他引:1  
In this paper a brief overview of the history of Fibre Metal Laminates Arall and Glare is given as background information for the other, technical articles in this journal. The story of the development of Fibre Metal Laminates is rather a unique story in the history of aircraft materials: A university laboratory invented, developed and certified an aircraft material. Many parties were involved naturally, yet the very heart of the activity was the Structures and Materials Laboratory of the Faculty of Aerospace Engineering of Delft University of Technology in The Netherlands. At the break of the world's largest passenger transport aircraft, the Airbus A380, in which a substantial part of the fuselage will be made of Glare, the glass fibre-aluminium version of Fibre Metal Laminates, it is a good moment to tell some of its history.  相似文献

ABSTRACT

In this paper, we introduce the notion of a cooperative game with multiple attributes where players can provide partial participations in multiple attributes and form coalitions. The power or influence of the players due to their multiple attributes is evaluated based on their memberships in the coalitions. Our game therefore, extends the notion of cooperative games with fuzzy coalitions. The Shapley function for this class of games is proposed as a rational and fair solution concept. Every fuzzy game stems out of a specific crisp game under the assumption that the players provide partial memberships in forming multiple coalitions simultaneously. We adopt similar techniques to obtain the cooperative games with multiple attributes from their crisp counterparts and subsequently determine their Shapley functions.  相似文献

在稀硫酸中添加硫脲对块体纳米晶纯铁腐蚀行为的影响   总被引:1,自引:0,他引:1  
研究了在稀硫酸溶液中添加硫脲(TU)对块体纳米晶工业纯铁(BNII)室温电化学腐蚀行为的影响,并与普通工业纯铁(CPII)的室温电化学腐蚀行为进行了比较.结果表明:将CPII在添加TU的稀硫酸溶液中浸泡5 min,其电化学阻抗(EIS)谱图中出现感抗弧.随着浸泡时间的延长,CPII的EIS谱图表现为一非圆心下偏的半圆;而在相同的条件下,BNII的EIS谱图表现为两个时间常数的容抗弧,表明硫脲对其腐蚀行为有促进作用.动电位极化(PDP)测试结果表明,两种材料的样品均出现阳极脱附现象.  相似文献

Interactive design has come about as a result of the intermingling of disciplines. As a consequence, the language it uses has become blurred - borrowed or stolen with little restraint from elsewhere. Though particular terms have become ubiquitous, the original concepts that lie behind them have been lost. This means that all too frequently they are no longer knowingly used. Usman Haque sorts the wheat from the chaff and brings clarity to bear on the vocabulary and thinking behind interactivity. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

The wind-driven nature of large lakes suggests that the accuracy of meteorological inputs is essential for hydrodynamic modelling. Moreover, coupling between the meteorological inputs and density stratification may also influence the simulated lake behavior. To investigate wind-driven large lake processes, a high-resolution coupled Delft3D-SWAN model was applied to Lake Ontario to simulate storm surges, surface waves, and circulation during two recent storm events. In both events, the sustained wind speeds approached 20 m s?1; however, variations in wind direction and duration altered the lake's surface wave and storm surge responses. The influence of different atmospheric inputs was investigated by comparing results from two spatially varied atmospheric models: the Rapid Refresh (RAP) and the High-Resolution Deterministic Prediction System (HRDPS). Hydrodynamic simulations using HRDPS were marginally better, with maximum root mean squared errors (RMSE) between modelled and observed water levels of 0.07 m, compared to 0.08 m with RAP. Predictions of the magnitude and timing of the maximum wave heights varied based on wind fields, with differences between predicted peak wave heights of up to 0.4 m. Both events occurred during a stratified period, allowing for a comparative evaluation of the influence of baroclinic and barotropic processes on the simulated surface wave and storm surge results. Simulations including the vertical density gradient gave a better representation of current velocities with depth and resulted in an improved prediction of peak storm surge magnitudes and surface water level behavior following the storms, reducing the RMSE by up to 12%.  相似文献
