11. He was honored for solving, in 1930, the inverse problem of the calculus of variations. 12. Professor Mura was also interested in the inverse problems . 13. This is a simple example of an inverse problem . 14. It is used to solve the inverse problem with incomplete input data, similar to local tomography. 15. The solution for sound speed, hence temperature, from the acoustic travel times is an inverse problem . 16. It will be a hard inverse problem that will get very bad signal to noise ratio. 17. Mathematically, this is an often difficult inverse problem . 18. Beals works on inverse problems in scattering theory, integrable systems, pseudodifferential operators, complex analysis, transport theory. 19. This is referred to as the inverse problem . 20. In common with other geophysical methods, reflection seismology may be seen as a type of inverse problem .
