Parabolic Source Identification Problem With Integral Condition

Journal of Mathematical Sciences
The aim of the present work is to study a source identification problem for the parabolic equation with a nonlocal integral condition. We give stability estimates for the solution of the source identification problem.

Source Identification in River Pollution Problems: A Geostatistical Approach [PDF]

Water Resources Research, 2005
The geostatistical method, formulated in the groundwater field, has been applied to identify contaminant sources in river pollution problems. The problem consists of recovering a contaminant source at a known location from a finite number of concentration measurements.

Source Identification in Remote Sensing Problems

SIAM Review, 1991
In remote sensing problems where a wavefield encounters a scattering body, the source wavelet can be extracted by calculating surface integrals which involve the incident or scattered wavefield. No knowledge of the scattering body is required. The general formulas require the field and its normal derivative; however, some geometries require only the ...

The source identification problem in electromagnetic theory

Journal of Mathematical Physics, 1997
The problem of the identification of the electromagnetic source which produces an assigned radiation pattern is ill-posed: the solution is, in general, not unique and it does not depend continuously on the data. In this paper we treat in detail these two aspects of the problem.

Meshless Collocation Method for Inverse Source Identification Problems

Advances in Applied Mathematics and Mechanics, 2015
Summary: A novel meshless scheme is proposed for inverse source identification problems of Helmholtz-type equations. It is formulated by the non-singular general solutions of the Helmholtz-type equations augmented with radial basis functions.
