Different geophysical methods provide information about various physical properties of rock formations and mineralization. In many cases, this is mutually complementary. At the same time, inversion data for a particular survey subject to considerable uncertainty ambiguity as causative body geometry intrinsic property contrast. One productive approach reducing jointly invert several types data. ...

Articulatory features are proved to be efficient in the area of speech recognition and synthesis. However, acquiring articulatory has always been a difficult research hotspot. A lightweight accurate model is significant meaning. In this study, we propose novel temporal convolution network-based acoustic-to-articulatory inversion system. The acoustic feature converted into high-dimensional hidde...

We present a phrasal inversion transduction grammar as an alternative to joint phrasal translation models. This syntactic model is similar to its flatstring phrasal predecessors, but admits polynomial-time algorithms for Viterbi alignment and EM training. We demonstrate that the consistency constraints that allow flat phrasal models to scale also help ITG algorithms, producing an 80-times faste...

The method of simultaneous PP-PS inversion has recently been developed and tested on the 3-D Blackfoot seismic data set. This paper shows the application of this method on 3C-2D seismic data from Pikes Peak oilfield. The inversion was accomplished with a newly installed inversion module in ProMAX. After careful prestack processing, five limitedoffset stacked sections for each of the vertical an...

Recently, the processing of aeromagnetic data to account for leveling has developed into the use of gradients. Utilizing multiple magnetometers allows for the measurement of magnetic gradients and minimizes the diurnal variation and other common-mode noise. We extend the use of these data to quantitative interpretation through 3D inversion. We make use of a well-known relationship between the d...

Teleseismic P-wave receiver functions and surface-wave dispersion measurements can be employed to simultaneously infer the shear-wave velocity distribution with depth in the lithosphere. Receiver functions are primarily sensitive to shear-wave velocity contrasts and vertical travel times and surface-wave dispersion measurements are sensitive to vertical shear-wave velocity averages, so that the...

A joint inversion method is developed to estimate the elastic constants of two elastic, homogeneous, isotropic media separated by a flat horizontal boundary. The method jointly uses P and S-converted wave reflection amplitude-versusangle (AVA) data and seeks the Poisson’s ratios of each layer, ratios of the densities and bulk modulus of the layers. The generalized linear inversion (GLI) method ...
