Universality of fragment shapes
The shape of fragments generated by the breakup of solids is central to a wide variety of problems ranging from the geomorphic evolution of boulders to the accumulation of space debris orbiting Earth. Although the statistics of the mass of fragments has been found to show a universal scaling behavior, the comprehensive characterization of fragment shapes still remained a fundamental challenge. ...
متن کاملScaling behavior of fragment shapes.
We present an experimental and theoretical study of the shape of fragments generated by explosive and impact loading of closed shells. Based on high speed imaging, we have determined the fragmentation mechanism of shells. Experiments have shown that the fragments vary from completely isotropic to highly anisotropic elongated shapes, depending on the microscopic cracking mechanism of the shell. ...
متن کاملMultiresolution Molecular Shapes
We introduce a multiresolution representation scheme for variable levels of detail of molecular shapes (shapes synthesized as sets of balls). In particular, we consider in our model the exact boundary computation of the the basic union of balls for CPK model and solvent accessible surface as well as the more complex rolling ball solvent contact surface and molecular skin. Our decimation/refinem...
متن کاملIntrinsic Shapes of Molecular Cloud
We conduct an analysis of the shapes of molecular cloud cores using recently compiled catalogs of observed axis ratios of individual cores mapped in ammonia or through optical selection. We apply both analytical and statistical techniques to de-project the observed axis ratios in order to determine the true distribution of cloud core shapes. We nd that neither pure oblate nor pure prolate cores...
