Seismic inversion by artificial neural networks.
(2001)
The first application is seismic inversion. Artificial neural networks were used to invert post-stack seismic data into the petrophysical attributes. This application involves two steps. In the first step, the seismic data, ...
AVO polarization attributes and hodograms.
(2001)
A case study using seismic data from the Gorgon field of the NW Shelf of Australia is done to validate the methodology. Application of this new scheme can help one recognize AVO anomalies and enhances AVO interpretation.
Mechanisms and rates of strength recovery in laboratory fault zones.
(2001)
The results of this investigation may be applied to explain observations of rapid strengthening along large, active crustal fault zones such as parts of the San Andreas Fault system in California and the Nojima fault in ...
Optical observations of lightning by the FORTE satellite: Terrestrial ground truth and implications for the interpretation of Jovian lightning data.
(2001)
Lightning and storm electrification have been studied from many different viewpoints and with many different instruments. The myriad of viewpoints and instruments often see the results or effects of different processes ...
A hierarchical, multiscale texture segmentation algorithm for real-world scenes.
(2001)
We also develop a way of objectively evaluating texture segmentation algorithms on natural and synthetic texture patches. Finally, our multiscale segmentation approach is demonstrated on several families of real-world ...
Pseudo-inverse imaging for ground penetrating radar data.
(2001)
Ground Penetrating Radar (GPR) is a proven method of characterizing the shallow subsurface. Most interpretations using GPR have relied upon raw data records or records that have been processed with seismic data processing ...
Static and dynamic behavior of multiphase porous media: Governing equations and finite element implementation.
(2001)
The mechanical behavior of porous media such as geomaterials is largely governed by the interactions of the solid skeleton (or grains) with the fluids existing in the pores. These interactions occur through the interfaces ...
Magnetic minerals: Understanding the processes of formation in soils and clays and identifying their presence in the rock record.
(2001)
This work presents results of biological formation of magnetite under a variety of laboratory conditions in a hydrocarbon-contaminated soil profile. Magnetite was formed only in biological samples but not in the abiotic: ...
