Source Reconstruction as an Inverse Problem
Inverse Problem techniques offer powerful tools which deal naturally with marginal data and asymmetric or strongly smoothing kernels, in cases where parameter-fitting methods may be used only with some caution. Although they are typically subject to some bias, they can invert data without requiring one to assume a particular model for the source. The Backus-Gilbert method in particular concentr...
متن کاملDetermination of a Source Term in an Inverse Heat Conduction Problem by Radial Basis Functions
In this paper, we propose a technique for determining a source term in an inverse heat conduction problem (IHCP) using Radial Basis Functions (RBFs). Because of being very suitable instruments, the RBFs have been applied for solving Partial Dierential Equations (PDEs) by some researchers. In the current study, a stable meshless method will be pro- posed for solving an (I...
متن کاملOptimal results for a time-fractional inverse diffusion problem under the Hölder type source condition
In the present paper we consider a time-fractional inverse diffusion problem, where data is given at $x=1$ and the solution is required in the interval $0
متن کاملSource optimization in the inverse geoelectrical problem
In electrical tomography, to determine the conductivity of a body or of a region of the earth, currents are injected on the surface and surface voltage responses are measured. Then the data are inverted to a conductivity distribution which matches the measurements. Usually all available data are used in the belief that pertinent information in the complete data set will be utilized. However, on...
متن کاملMulti-Source Family Reconstruction
The complex problem of automatic family reconstruction on the basis of multiple historical sources can only be solved within the framework of a transparent and modular system. The source information (gathered from multiple sources in various tables in the Source Database) should be transformed and normalized in such a way that a source-independent representation is realized (in a second, indepe...
