摘要:
Method of processing seismic data corresponding to acquisitions carried out in a medium exhibiting azimuthal anisotropy, characterized in that for two sets of data corresponding, for one and the same seismic variable and for one and the same ground zone, to at least two different source/azimuth receiver pair sectors, an average between the data which correspond to the azimuth considered and data which correspond, for the same variable and the same ground zone, to a perpendicular azimuth sector is determined for each of the azimuths considered, and in that an estimate of the part common to the two sets thus obtained of averaged data is determined.

The present invention relates to a new method for treating or processing a cross-linked hyaluronan hydrogel prior to its use in applications involving three-dimensional cell culture. The invention also relates to cross-linked hyaluronan hydrogels prepared by such a method and to their use in 3D cell culture, stem cell/tissue engineering, drug discovery, toxicology testing, and broad cell biology applications.

摘要:
The invention relates to a method for determining, for a detector placed on the surface of the seabed, the vertical propagation time and the velocity of propagation in the water of a wave emitted from an emission point. The method includes: emitting a wave from the emission point; recording the wave received by the detector; determining the vertical propagation time by, where tdir is the direct wave propagation time between the emission point and the detector, and tmul is the propagation time of the first multiple wave between the emission point and the detector; and determining the velocity of propagation of the wave, where X is the distance between the emission point and the water-surface point that is vertical to the detector.

A method of determining the position of a detector disposed under the sea, comprising the following steps: emit N waves from N emission points, record the propagation time of said wave between each emission point and the detector; determine the P time intervals Ti, with P≧1 such that, for each time interval Ti, there exist Mi emission points, Mi≧3 for 1≦i≦P, whose propagation times lie in the time interval, determine for each time interval Ti of the circle which passes closest to the Mi points whose propagation time lies in said time interval, and then determine the position of the detector as being the barycenter of the P centers of the circles determined previously.
