In this paper, we discuss stability and Tikhonov regularization for the integral equation of the rst kind with logarithmic kernel. Since the kernel is analytic in our case, the problem is severelyâ€¦ (More)

This paper is devoted to the inverse problem of identifying a spatially varying coe cient in a linear elliptic di erential equation describing the ltration of groundwater. Practice suggests that theâ€¦ (More)

This work describes the design, development, and characterization of an ionization chamber to detect and locate gamma ray sources with intensities down to 100 mu Gy h(-1). The results show thatâ€¦ (More)

We consider a linear operator equation with noise in the operator and the right-hand side. As a concept, the ill posedness of the problem is composed of the ill-posedness with respect to the operatorâ€¦ (More)
