... We study ergodic properties of random maps defined as collections of nonsingular maps $f_1,\dots,f_w$ from a compact metric space $(X,\rho)$ into itself taken with probabilities $p_1,\dots,p_w$ ($\sum_i^wp_i=1$) and considered as Markov processes on $X$. ... In the first situation, when the random map is expanding on average, we mainly follow ideas borrowed from the theory of piecewise expanding maps and the corresponding Banach space is a version of the space of functions of bounded variation on $X...

A. A. Sukhanov . Modern Methods for Space Flight Dynamics and Their Applications . ... The following effective mathematical methods are suggested for solution of different space flight dynamics problems: . 1) A simple method for the calculation of the state transition matrices of the first and second order. The method allows calculation of the matrices for any orbit types. ... 3) A double planet swingby optimization. ... Applications of the methods are given. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...

Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...
