... 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. ...

... 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 . ...

We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...
