Dynamics of solid neon monolayers.
The dynamics of two-dimensional solid neon is investigated within the self-consistent phonon theory. Phonon frequencies and lifetimes and the one-phonon dynamic form factor are evaluated as a function of temperature and lattice spacing in the self-consistent harmonic approximation with the cubic anharmonic term added. Two-dimensional solid neon is found to be highly anharmonic. It becomes mecha...
متن کاملThe infrared spectrum of HOOH+ trapped in solid neon.
When a Ne:H(2)O(2) mixture is codeposited at 4.3 K with a beam of neon atoms that have been excited in a microwave discharge, three new, photosensitive absorptions appear which can be assigned to the three infrared-active vibrational fundamentals of trans-HOOH(+). When the Ne:H(2)O(2) deposition system is pretreated with the vapors of D(2)O, the product absorptions include new peaks which can b...
متن کاملSpectral descriptors for deformable shapes
Informative and discriminative feature descriptors play a fundamental role in deformable shape analysis. For example, they have been successfully employed in correspondence, registration, and retrieval tasks. In the recent years, significant attention has been devoted to descriptors obtained from the spectral decomposition of the LaplaceBeltrami operator associated with the shape. Notable examp...
متن کاملContribution of Spectral Shapes to Tone Perception
Tones in tonal languages are defined based on the characteristics of their fundamental frequencies. However, it has been shown that fundamental frequencies alone do not lead to good tone identification, either by human or machines. This paper reports a study based on tone perception experiments in which participants identified Thai tones from recorded mono-syllabic, bi-syllabic, and trisyllabic...
متن کاملProbabilistic matching of solid shapes in arbitrary dimension
Determining the similarity between objects is a fundamental problem in computer vision and pattern recognition, but also in other fields of computer science. This thesis concentrates on the matching problem, which has received a lot of attention in Computational Geometry. Given a class of shapes S, a set of transformations T , mapping shapes onto shapes, and a distance measure d on S, the match...
