USSR Venus Orbiters . ... Venera 15 and Venera 16 were a two-spacecraft mission designed to use 8-centimeter (3-inch) band, side-looking radar mappers to study the surface properties of Venus . ... Each spacecraft consisted of a synthetic aperture radar (SAR) and a radio altimeter. ... The Venera 15 and 16 synthetic aperture radar (SAR) systems were identical, and were used to map the surface of Venus at a resolution of 1 to 2 kilometers (.6 to 1.2 miles) over a period of 8 months. ...

... 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. ...

... At the simplest level of modelization, these phenomena are described by reaction-diffusion equations. The theory of this type of equation is far away from being fully understood but one can give however several results providing in some cases existence of solutions and their qualitative behaviour. ... Reaction-diffusion equations. ... Theory of uniformly elliptic equations: existence, regularity, Schauder theory, Agmon-Douglis-Nirenberg theory, Harnack estimates, boundary Harnack principle. ...

... The formation of the disks of disk galaxies remains poorly understood. ... Many disk galaxies have only the thin disk component, with no bulge or significant thick disk. ... Almost all disk galaxies have an exponential radial surface brightness distribution. The reason for this exponential form is not known; nor is it known when the exponential form is established. ... We would compare low redshift galaxies observed in the I band with galaxies at z =0.5 in the J band and at z =1 in the H band. ...

Authors: Yu.G. Shevelev , V.A. Marsakov , . ... 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. ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...
