Abstract: In seismic inversion, the subsurface model can be parameterized by a truncated Fourier series, and then, the inversion problem is the inversion of the Fourier coefficients. To improve the ...

Abstract: Two sets of rotationally invariant, horizontal, and vertical fractures permeated in a homogeneous isotropic background rock can yield a long-wavelength effective orthorhombic medium.

Boise’s location in a valley often causes it to experience inversions, but the current one has been unusually long. The inversion even caused Treasure Valley residents to miss out on the beauty of ...
