Kollokvium om at udstille kunst og naturvidenskab. Steno Museet, Danmarks Videnskabshistoriske Museum, Århus, 25. september 2006. In the fall of 2006, the Steno Museum (Aarhus, Denmark) exhibited the installation Room One created by the American artist Rosamond Purcell. This installation consists of a full-size model of Museum Wormianum, the Danish physician Ole Worm’s curiosity cabinet, dating from the 17th century. This is a work of art – yet it depicts a naturalist’s laboratory. When one adds that it has also been called the first museum in Denmark, it seemed an obvious step to make the artwork the occasion of a symposium on the relationship between art, science and museums. At this symposium, the artist, along with a number of science historians and museum curators, discussed the definitions of art and science then and now, and spoke about the attempts to transcend the disciplinary boundaries that take place within the museums. Different ways of exhibiting were brought into focus, and Purcell’s installation formed the basis for many interesting discussions about the museum as a place of learning and of aesthetic experience.

Concrete is used in tower, and steel is used in anchor zone. It can make full use of the two materials’ nature. It can not only satisfy the tower’s stressed aptitude, but also can reduce the cost of construction. In this paper, the full size model has been designed and constructed. The test investigation of the statical performance have been proceeded. The results show that the neotype anchor system can make full use of the materials’ nature and is in good working order. The anchor system with enough bearing capacity satisfies the operating requiements of the cable-stayed bridge.

At present, small radius looped prestressed tendons have been widely used in cable-stayed bridge anchorages; the error limitation of stretch elongation in prestressed technology is 6 percentage, but in field it always exceeds the limitation. In this study, the main factors which lead to the stretch elongation were analyzed through a field full-size model test of a cable-stayed bridge. Moreover, the behaviors of ring prestressed tendons were studied for different penetrating strands technology and some advices and suggestions were finally made to offer an example for similar engineering.

Computer modeling and simulations on the crashworthiness of aircraft using validated models have provided insight into the energy-absorption characteristics of structures and have allowed parametric studies in the evaluation of different crash energy management designs. In this study, the dynamic responses of a detailed and simplified full-size, and scaled fuselage models in vertical impact are investigated. The detailed full-size model, constructed from a Boeing 737 mid-fuselage section, consists of a stiff auxiliary fuel tank and a cargo door. The detailed full-size model is dropped from a height of 4.26 m (14 ft) onto a rigid surface, which corresponds to a vertical impact speed of 9.14 m/s (30 ft/s). The drop simulations are performed using the non-linear explicit code, LS-DYNA. Correlation of the detailed full-size model with the physical test conducted by the Federal Aviation Administration is demonstrated. Scale modeling technique applied to the aircraft fuselage section is utilized and for scaling purposes, a simplified full-size model is constructed without the auxiliary fuel tank and cargo door. The crash responses of the simplified full-size models in relation to the detailed full-size model are shown and discussed. The scaling approach involves geometrical scaling of the simplified full-size model with scale factors of 1/5th, 1/10th and 1/20th. The vertical impact simulations of the scaled models are carried with identical impact speed as that of the detailed full-size model. General scaling laws for geometry, mass, velocity, acceleration and forces are utilized to predict the results for the scaled models. The approach and results presented in this study have demonstrated an efficient and innovative method on the design and crashworthiness of a fuselage section.
