... ICND-96, Saratov, Russia. ... And though a number of efficient methods of digital sound compression is developed by far, there is still a need in new efficient methods. In this report we study a possibility of application of fractal methods to compression of speech signals. ... In this method, a speech frame is divided into larger pieces called domains, and smaller ones called regions, and an optimal set of affine transformations of domains into regions is calculated. ...

... Up: Data Analysis Applications . Previous: Mixing IRAF and Starlink Applications - FIGARO under IRAF . ... An infrared-array reduction and analysis package which is written in the IRAF environment has been developed to handle the huge amount of data obtained at the Teide Observatory using the 1.5 m Carlos S?nchez Telescope with the new infrared Camera/Instituto de Astrof?sica de Canarias(IRCAM/IAC). ... One of the advantages of this package is that it can easily handle the large amount of data. ...

... These sources are much more likely to be gravitationally lensed by intervening galaxies as compared with sources discovered in surveys in other wavebands. ... The effect of lensing by clusters is then discussed briefly. This is expected to increase the source confusion noise in a Planck survey in the directions of clusters, and could provide information about galaxies with flux densities that are too faint to be detected directly by Planck . ... 2 The properties of galaxy--galaxy lensing . ...

Organisers: Michel Balazard (CNRS, Laboratoire Poncelet) , Michael Tsfasman (CNRS, Laboratoire Poncelet, Institute for Information Transmission Problems) , Alexey Zykin (Laboratoire Poncelet, State University Higher School of Economics) . ... In this talk, we first motivate the study of zeta functions in families. Then we focus on the study of zeta functions in families of global fields and more specifically that of their logarithmic derivatives (joint work with A. Zykin). ...

... Physical Properties of Crystals . ... The course is an introduction into crystal physics and consists of two introductory parts devoted to the basics of crystallography and tensor analysis and six main chapters in which the physical phenomena in anisotropic medium are described by the example of the elastic, electrical and magnetic crystal properties. The effect of symmetry is also discussed. ... Effect of symmetry on crystal properties. ... Effect of symmetry on crystal optical properties. ...

The notes in their current form concern only 2 but main for astronimy aspects of the optical properties of cosmic dust - the ability to extinct and polarize transmitted radiation. The corresponding obervational effects the extinction and polarization (not due to scattering) plaied and plays till now the primary role in astrophysical effects of cosmic dust considered in the literature. ...

... We present Very Large Array observations of the intermediate mass pre-main-sequence stars UX Ori and CQ Tau at 7mm, 3.6cm, and 6cm. ... Both stars are detected at 7mm but not at longer wavelengths, which confirms that the millimeter emission is dominated by dust. ... The observations do not spatially resolve the 7mm emission. ... The CQ Tau system exhibits a spectral index in the millimeter range of alpha_mm~2.6, consistent with values commonly found for disks around pre-main-sequence stars. ...
