Eigenvibrations of laterally inhomogeneous Earth models

Surface Waves in Laterally Inhomogeneous Regions

Computer Simulation of Ion Beam Analysis of Laterally Inhomogeneous Materials

The program STRUCTNRA for the simulation of ion beam analysis charged particle spectra from arbitrary two-dimensional distributions of materials is described. The code is validated by comparison to experimental backscattering data from a silicon grating on tantalum at di erent orientations and incident angles. Simulated spectra for several types of rough thin layers and a chessboard-like arrang...

Inhomogeneous Parsimonious Markov Models

We introduce inhomogeneous parsimonious Markov models for modeling statistical patterns in discrete sequences. These models are based on parsimonious context trees, which are a generalization of context trees, and thus generalize variable order Markov models. We follow a Bayesian approach, consisting of structure and parameter learning. Structure learning is a challenging problem due to an over...

Exact Inhomogeneous Cosmological Models

We present new exact inhomogeneous vacuum cosmological solutions of Einstein’s equations. They provide new information about the nature of general cosmological solutions to Einstein’s equations. PACS 04.20.Jb, 98.80H, 04.30.-w Inhomogeneous and anisotropic solutions of Einstein’s equations are of great interest because of the subtleties of their non-linearity and the clues they offer about the ...

D ec 1 99 8 Quantitative study of laterally inhomogeneous wetting films

Based on a microscopic density functional theory we calculate the internal structure of the three-phase contact line between liquid, vapor, and a confining wall as well as the morphology of liquid wetting films on a substrate exhibiting a chemical step. We present a refined numerical analysis of the non-local density functional which describes the interface morphologies and the corresponding li...
