Business Cases

  • Data assimilation system for seismic waves - development

    We have developed a data assimilation system that optimizes the mass density and elastic constants of seismic wave simulation model based on ground-based pseudo-seismic observation data.

    Although it is difficult to directly observe the subsurface mass density and elastic constants, they can be estimated by data assimilation using seismic data from the ground.

    The data assimilation method used was the four-dimensional variational method (4DVar or adjoint method). This method uses an adjoint model based on a simulation model. This allows us to optimize the parameters over a period of time to satisfy the governing equations of the simulation model.

  • Noise reduction algorithm by wavelet analysis - R&D

    A system was developed which experiments and analyze reduction algorithms of noise included in speech or vibration by using wavelet analysis related techniques.

    Global GCV Method, Level-Dependent GCV Method

    Calculating threshold of minimizing GCV (Global Cross-Validation) against discrete wavelet coefficients, this method reduces noise by eliminating components less than the threshold.

    Tree-Structured Method

    Calculating sub-tree having strength more than some threshold from wavelet coefficients tree, this method reduces noise which have no relations with the essential waveform. Implemented Dyadic CART (Classification And Regression Trees) algorithm for searching optimal sub-tree. This algorithm does model regression against (sparse) binary-tree whose node has numerical value by posing penalty for complexity of the binary-tree.

    To develop this system, we have needed processing of complex data structure, but MATLAB is not so good at such a work, so we implemented core algorithm in C++ and let MATLAB call it as a plug-in.
