    Possibilities of determination of alteration degree of rocks by thermogravimetry

    Rhyolite-rhyodacite tuff samples were analysed by X-ray powder diffraction, ICP-OES and thermogravimetric (TG) methods to determine mineral and major element composition as well as different types of bound wat...

    Generalized band matrices and their inverses

    The idea of defining the generalized band matrices is based on the recognition that several pattern matrices and their inverses have low rank submatrices in certain domains. Theoretical considerations concerni...

    On the inverse of band matrices

    Band matrices and Green's matrices have been defined by E. Asplund [1]; his basic theorem shows their relationship. The definition of one-pair-matrices was given by F. R. Gantmacher and M. G. Krein [5]; they show...

    Optics of thin films in the soft x-ray and vacuum UV regions

    The final results of this paper are expressed by equations (4.21)–(4.27). We can see that the formulae for the complex reflectivities rR, rL and transmittivity t of a stack are formally the same as those deduced ...
