Other examples of PDEs that finite-difference methods can solve include option pricing (in mathematical finance), Maxwell’s equations (in computational electromagnetics), the Navier-Stokes equation (in computational fluid dynamics), and others. The simple parallel finit...
We study the diffraction of plane elastic waves by a grating of circular holes in an elastic matrix, using a multipole formulation to determine scattering matrices, for both the scalar (out–of–plane shear) and vector (plane–strain) problems. We use these matrices in a recurrence procedure ...
A total of 122 children (aged 8–11 years) with spherical equivalent refraction (SER) between − 1.00 D and − 4.00 D were enrolled in this prospective study and randomly assigned to four groups: 5.0 mm-BOZD OK, 6.2 mm-BOZD OK, DISC, and single-vision SCLs. Children in ...
Learn about difference of sets such as difference between two sets, difference between three sets along with the notations, properties and solved examples, here at BYJU’S.
seismic refractionAn iterative tomographic inversion scheme is presented for determination of 2-D velocity structure from seismic refraction first-arrival traveltimes. the method is suited to refraction profiles where source/receiver spacings are denser than for conventional profiles. the inversion method ...
Distance between two points in a cartesian plane can be calculated using a formula in the Cartesian plane. Learn how to derive the distance between two points formula along with solved examples here at BYJU'S.
electrons in the conduction band of n-GaAs generate FR fluctuations that can be detected at photon energies far below the low temperature GaAs bandgap (for example, at sub-gap wavelengths from 830–900 nm), owing to the long tails of the dispersive indices of refraction (see inset). ...
The deflection of the electromagnetic field vectors due to refraction at the glass-sample interface was neglected, as well as the loss of intensity. For a more accurate investigation of the impact of refractive index mismatch on localisation precision, these effects would have to be included; the...
In addition, the effect of initial model selection and frequency combination on FWI is analyzed. Examples using numerical simulations and FWI calculations are used to verify the efficiency of the proposed method. 展开 关键词: Full-waveform inversion rugged topography attenuation boundary condition finite...
