The spherical deformation model.
Miller et al. (1994) describe a model for representing spatial objects with no obvious landmarks. Each object is represented by a global translation and a normal deformation of a sphere. The normal deformation is defined via the orthonormal spherical-harmonic basis. In this paper we analyse the spherical deformation model in detail and describe how it may be used to summarize the shape of star-...
متن کاملSpherical Deformation for one-dimensional Quantum Systems
System-size dependence of the ground-state energy E is investigated for N-site onedimensional (1D) quantum systems with open boundary condition, where the interaction strength decreases towards the both ends of the system. For the spinless Fermions on the 1D lattice we have considered, it is shown that the finite-size correction to the energy per site, which is defined as E/N − limN→∞ E /N , is...
متن کاملSpherical self-consistent atomic deformation model for first-principles energy calculations in ionic crystalline solids.
We present a first-principles method @called spherical self-consistent atomic deformation ~SSCAD!# for calculating the energy per unit cell in ionic crystalline solids. SSCAD is a density-functional method using the local-density approximation ~LDA!. Wave functions are localized about each ion, resulting in a single-particle Schrödinger’s equation for each ion. To simplify the calculation, we s...
متن کاملMechanical deformation of spherical viruses with icosahedral symmetry.
Virus capsids and crystalline surfactant vesicles are two examples of self-assembled shells in the nano- to micrometer size range. Virus capsids are particularly interesting since they have to sustain large internal pressures while encapsulating and protecting the viral DNA. We therefore study the mechanical properties of crystalline shells of icosahedral symmetry on a substrate under a uniaxia...
متن کاملSpherical deformation of compliant substrates with semiconductor device islands
This article explores, through experiments and finite element analysis, the ability to plastically deform thin-film semiconductor structures on deformable substrates to spherical cap shapes without cracking the semiconductor layers. The major challenge involves contending with the large strain due to extreme deformation that will crack uniform stiff layers, such as silicon or silicon nitride. B...
