New Approaches in 3D Geomechanical Earth Modeling
In this paper two new approaches for building 3D Geomechanical Earth Model (GEM) were introduced. The first method is a hybrid of geostatistical estimators, Bayesian inference, Markov chain and Monte Carlo, which is called Model Based Geostatistics (MBG). It has utilized to achieve more accurate geomechanical model and condition the model and parameters of variogram. The second approach is the ...
متن کاملA hybrid boundary element-finite element approach to modeling plane wave 3D electromagnetic induction responses in the Earth
A novel hybrid boundary element-finite element scheme which is accelerated by an adaptive multi-level fast multipole algorithm is presented to simulate 3D plane wave electromagnetic induction responses in the Earth. The remarkable advantages of this novel scheme are the complete removal of the volume discretization of the air space and the capability of simulating large-scale complicated geoele...
متن کاملA fully anisotropic Sobolev inequality
Let n ≥ 2 and let A : Rn → [0,∞] be any convex function satisfying the following properties: A(0) = 0 and A(ξ) = A(−ξ) for ξ ∈ R; (1.1) for every t > 0, {ξ ∈ R : A(ξ) ≤ t} (1.2) is a compact set whose interior contains 0. Observe that A need not depend on the length |ξ| of ξ nor be the sum of functions of its components ξi, i = 1, . . . , n. The purpose of this note is to exhibit an inequality ...
متن کاملA New Approximation for 3D Electromagnetic Scattering in the Presence of Anisotropic Conductive Media
Integral equations have been widely used to solve EM scattering problems, including those arising in geophysical prospecting and antenna applications. Hohmann (1971) first discussed the application of integral equations to the simulation of two-dimensional (2D) subsurface geophysical problems. Since then, a number of applications and developments have been reported that include 3D EM scattering...
متن کاملImprovement of Electromagnetic Forces in a Single-Phase Induction Motor by Providing a New Winding Distribution
Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
