Curved Folded Plate Timber Structures
Current research at the laboratory for timber construction IBOIS at EPFL focuses on shell structures. Two main families are investigated: shells made of linear elements, as timber rib shells, and shells made of surface elements, typically folded plate structures. With regard to timber rib shells, bent linear timber elements are used to create the shape of a shell. With folded plate structures, ...
متن کاملA Falling, Folded String
This classic problem was brought to the author’s attention by Johann Otto. This view seems to be advocated by Routh (1896) in Ex. 4, p. 82 of [13]. Examples of falling chains were often considered at Cambridge U. [11, 12, 13, 14, 16, 18, 19], as recounted in a footnote on p. 80 of [13]: Problems on infinitesimal impulses were solved in the lecture room of the late Mr Hopkins as long ago as 1850...
متن کاملCurved QCD string dynamics
We consider the effects of going beyond the approximation of a straight string in mesons by using a flexible flux tube model wherein a Nambu-Goto string bends in response to quark accelerations. The curved string is dynamically identical to the straight string even for ultra-relativistic mesons except for a small additional radial momentum. We numerically solve the curved string model in the ca...
متن کاملDetection of Protrusions in Curved Folded Surfaces Applied to Automated Polyp Detection in CT Colonography
Over the past years many computer aided diagnosis (CAD) schemes have been presented for the detection of colonic polyps in CT Colonography. The vast majority of these methods (implicitly) model polyps as approximately spherical protrusions. Polyp shape and size varies greatly, however and is often far from spherical. We propose a shape and size invariant method to detect suspicious regions. The...
متن کاملRealtime Shading of Folded Surfaces
In this paper we present a new, simple, and efficient way to illuminate folded surfaces with extended light sources in realtime including shadows. In a preprocessing step we compute the parts of the surrounding environment that are visible from a set of points on the surface and represent this information in a binary visibility map. The illumination of the scene, i.e., incoming light from diffe...
