Phase inversion of seismic data

SEG Technical Program Expanded Abstracts 2004, 2004
Summary Waveform inversion requires extracting a reliable low frequency content of seismic data for estimating of the low wave number velocity model. The low frequency content of the seismic data is usually discarded or neglected because of the band-limited response of the source and the receivers.

Shape Inversion from Phase Shifts

1993
The integral representation for the scattered far-field is first derived with the help of the partial wave decomposition of the fundamental solution. The integral representation for the phase shifts is obtained from the integral representation of the scattered far-field.

Inverse Micellar Lyotropic Cubic Phases

1999
Many amphiphilic molecules (surfactants, biological lipids, etc) can form three-dimensionally ordered liquid-crystalline structures in the presence of water [1, 2]. The most common of such complex lyotropic mesophases are the bicontinuous cubic phases [3], which appear to be based upon underlying periodic minimal surfaces [4].

Phase Inversion in Mixer Settlers

1992
ABSTRACT The phenomenon of phase inversion is one of the major causes of operating problems in industrial mixer-settler equipment. However, although the avoidance of inversion is one of the most important design criteria, the study of inversion has not attracted as much research attention as other aspects of liquid-liquid mixing.

Nanoemulsion Formation by Phase Inversion Emulsification:  On the Nature of Inversion

Langmuir, 2006
Emulsification processes are usually characterized by the way they allow the surfactants, as well as the dispersed phase, to be incorporated into emulsions. A model cyclohexane-in-water emulsion using a pair of polyoxyethylene nonylphenyl ether surfactants, one oil-soluble and one water-soluble, was considered.

Membranes Prepared via Phase Inversion

2011
The most important part in membrane reactors is the membrane itself. The traditional membrane separation processes such as reverse osmosis, micro-, ultra- and nanofiltration, electrodialysis, pervaporation, and so on, already largely used in many different applications, are today combined with membrane systems as catalytic membrane reactors.
