2. 5-D finite-element CSAMT numerical inversion is an inversion method based on 2. 5-D finiter-element forward modeling and CSAMT-RRI sensitivity matrix approximative computation as well as pseudo-1-D inversion method.
Coming from elastic wave equation in VTI me- dia,by the aid of elastic parameters of VTI media and Thomsen parameters and combining with Kelvin-Christoffel equation, the paper deduced quasi P-wave equation in VTI media and implemented its forward simulation.
The introduction of quasi-neural network BP algorithm,firstly solved the fast 3D forward problem,then the breakthrough of limitation from inversion parameter dimensionality,realized the fast convergence,so that effectively solved the inverse problem with two or multiple density interfaces.
The second part deals with the unsolved problem put forward by Bennett  by showing that there is at least one payoff which is balanced, partnered and equal gains aspiration.
In this paper, a new optimal design criterion-joint model and criterion optimal design criterion is put forward.
In this paper a generalized defaultable bond pricing formula is derived by assuming that there exists a defaultable forward rate term structure and that firms in the economy interact when default occurs.
Discontinuous galerkin finite element method for a forward-backward heat equation
A space-time finite element method, discontinuous in time but continuous in space, is studied to solve the nonlinear forward-backward heat equation.
With the experimental study on forward simulation of anomalies given by the superposition of six objects and measured data in Songliao plain, Northeast China, the shape, size and depth of the buried objects were estimated in the study.
Finite difference time domain method forward simulation of complex geoelectricity ground penetrating radar model
The ground penetrating radar (GPR) forward simulation all aims at the singular and regular models, such as sandwich model, round cavity, square cavity, and so on, which are comparably simple.
The Mur super absorbed boundary condition is adopted to solve the super strong reflection on the interceptive boundary when there is the forward simulation.
And a self-made program is used to process forward simulation to two typical geoelectricity model.
The forward problem is to solve the natural frequencies through a cracked structural model and the inverse problem is to quantitatively determine the crack parameters using the experimental testing frequencies.
Then, the one-dimensional crack element of B-spline wavelet on the interval (BSWI) was built to solve the forward problem.
Another effect of their application is a substantial decrease in the dimensions of the modeling domain and therefore in the time required to solve the forward problem.
