Time-reversed imaging as a diagnostic of wave and particle chaos

RK Snieder, JA Scales - Physical Review E, 1998 - APS
In the presence of multiple scattering, waves and particles behave fundamentally differently.
As a model for the stability of the temporal evolution of particle and wave propagation, a …

The origin of the 100,000 year cycle in a simple ice age model

RK Snieder - Journal of Geophysical Research: Atmospheres, 1985 - Wiley Online Library
A one‐dimensional nonlinear ice age model developed by J. Imbrie and JZ Imbrie was
used to investigate the 100,000 year cycle in climate records. It was already known that the …

The stability of one-dimensional inverse scattering

HJS Dorren, EJ Muyzert, RK Snieder - Inverse Problems, 1994 - iopscience.iop.org
The stability of one-dimensional inverse scattering is discussed. The analysis is performed
analytically using perturbation theory for reflection coefficients that are rational functions of …

Shear wave velocity structure in North America from large‐scale waveform inversions of surface waves

D Alsina, RL Woodward… - Journal of Geophysical …, 1996 - Wiley Online Library
A two‐step nonlinear and linear inversion is carried out to map the lateral heterogeneity
beneath North America using surface wave data. The lateral resolution for most areas of the …

Shear‐wave velocities under the Transantarctic Mountains and Terror Rift from surface wave inversion

S Bannister, RK Snieder… - Geophysical Research …, 2000 - Wiley Online Library
Rayleigh wave data between 20 and 120s period recorded in the western Ross Sea region
of Antarctica are inverted using the waveform inversion technique described in Passier and …

On the presence of intermediate-scale heterogeneity in the upper mantle

ML Passier, RK Snieder - Geophysical Journal International, 1995 - academic.oup.com
Power spectra of tomographic models of the entire earth and of models of Europe and the
Mediterranean area are compared. This comparison reveals a discrepancy (a factor 15–30) …

Bias in reported seismic arrival times deduced from the ISC Bulletin

AHE Röhm, J Trampert, H Paulssen… - Geophysical Journal …, 1999 - academic.oup.com
The accurate timing of seismological data is crucial for most quantitative examinations in
seismology. We present evidence that traveltime data from many stations contain systematic …

An acoustic Lippmann-Schwinger inversion method: Applications and comparison with the linear sampling method

AC Prunty, RK Snieder - Journal of Physics Communications, 2020 - iopscience.iop.org
We introduce an imaging method based on solving the Lippmann-Schwinger equation of
acoustic scattering theory. We compare and contrast the proposed Lippmann-Schwinger …

Using differential waveform data to retrieve local S velocity structure or path‐averaged S velocity gradients

ML Passier, RK Snieder - Journal of Geophysical Research …, 1995 - Wiley Online Library
An algorithm is presented which uses the surface waveforms originating from one event
recorded in two stations which are located close to each other. The waveforms are inverted for …

Theory of the linear sampling method for time-dependent fields

AC Prunty, RK Snieder - Inverse Problems, 2019 - iopscience.iop.org
The linear sampling method seeks to localize the unknown source of an observed, time-dependent
field. The unknown source could be, for example, a scatterer embedded within a …
