It is well known that the parabolic partial differential equations in two or more space dimensions with overspecified boundary data, feature in the mathematical modeling of many phenomena. In this article, an inverse problem of determining an unknown time-dependent source term of a parabolic equation in general dimensions is considered. Employing some transformations, we change the inverse prob...

The angular power spectrum of the cosmic microwave background ~CMB! contains information on virtually all cosmological parameters of interest, including the geometry of the Universe (V), the baryon density, the Hubble constant (h), the cosmological constant (L), the number of light neutrinos, the ionization history, and the amplitudes and spectral indices of the primordial scalar and tensor per...

The recession flow analysis of Brutsaert and Nieber [1977] extended by Troch et al. [1993] to estimate aquifer parameters (saturated hydraulic conductivity and mean aquifer depth) is examined by means of a numerical model. It is found to be reliable for the estimation of the catchment-scale saturated hydraulic conductivity and mean aquifer depth. Increasing the complexity of the synthetic water...
