Normalizations of hyperband

Abstract

Mission and proof of existence theorem for hyperband m n SH  A which carrier conjugated system (; * ) of planar elements are examined: the tangent subbundle of (; * ) -planes (-subbundle) and the tangent subbundle of lines (* -subbundle). Internal beams of normalizations of hyperband m SH and its tangent subbundles in the second-order differential neighborhood are constructed.

Implementation persistent scatterers interferometry in MATLAB environment on a high performance computer cluster

Abstract

The features of the method implementation Persistent Scatterers Interferometry in MATLAB environment on a high performance computer cluster are considered. The process and results of interferometric processing of multi-time measurements made by radar ALOS/PALSAR in 2007—2011 is described. For processing software package developed used high-precision evaluation of the displacement of man-made objects. The technology publication of displacement velocity of terrestrial surface on the basis of GeoServer and Google Maps services is offered.

Numerical recovering an absorption coefficient by BC-method

Abstract

A numerical algorithm for solving inverse dynamical problem recovering an absorption by the boundary control method is developed. The absorption coefficient is determined independently of a speed of sound, which can be an arbitrary smooth positive function. The results of numerical experiments are represented.
