In this work, we applied a Bayesian time-lapse (4D) seismic inversion to deep-water heavy oil field located in the Campos Basin (Brazil). procedure, differences of amplitudes baseline and repeated surveys are input calculate changes acoustic impedances. To ensure quality results, parametrization was performed by analyzing anomalies resolution signal-to-noise ratio with different values paramete...

New high resolution seismic data (Subbottom Chirp) coupled to high resolution Multibeam bathymetry collected in the frame of the Stromboli geophysical experiment aimed at recording active seismic data and tomography of the Stromboli Island are here presented. The Stromboli geophysical experiment has been already carried out based on onshore and offshore data acquisition in order to investigate ...

Estimation of the tissues mechanical properties of is an important information to the pathologies diagnosis. A novel ultrasound-based methods use shear wave dispersion for this purpose. This paper describes the Magneto Motive Ultrasound (MMUs) implementation to evaluate mechanical parameters of paraffin phantoms. This technique can be applied in vivo as an alternative to biopsy. Ultrasound equi...

Updraft vertical velocity is an important dynamical quantity which is strongly related to storm intensity and heavy precipitation. It can be calculated by direct observations, NWP model, and geostationary satellites which can provide the possibility of measuring this quantity with high temporal resolution. This research analyzed updraft velocity based on six derived parameters from INSAT3-D and...
