... COMPUTER SIMULATION OF RADIOWAVE MULTIPLE SCATTERING EFFECTS IN IONOSPHERE USING MONTE-CARLO METHOD . ... Distribution of reflected radiation on the ground is computed. ... Such influence can be remarkable if the scattering is multiple, i.e. the optical thickness for the scattering process is considerably greater than a unit. ... Radiation energy transfer in the slab is modeled by distribution of some particles carring small portions of radiation energy. ... The isotropic plasma approximation is...

G., European Space Agency, Research and Scientific Support Department, ESA/ESTEC, Noordwijk, The Netherlands, greg.michael@esa.int An algorithm for autonomous identification of crater centres from topography data has been improved in accuracy since [1,2] by taking account of the slope direction on the interior of the crater rim. ...

... SHORT TERM PREDICTION OF POWER SOLAR FLARES FROM SSRT DATA . The algorithm for short term prediction of powerful solar flares, based on SSRT data, includes microwave emission characteristics in total and polarized flux, the structure of active region (AR) magnetic field at the photospheric level, and H a patrol data. ... During this period, 7 AR's crossed the solar disk, in which 20 flares of importance ? ... Data on AR's and magnetic fields were received from the Sayan observatory by teletype. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... Estimates are obtained for the limits of variability of the parameters of harmonic components that can be determined on a specified time grid. ... The second is the same as the first, but for model time series on a temporal grid determined by the real series with model harmonic components and with the parameters for the harmonic components obtained by solving the first problem. ... Thus, our problem involves choosing a method for determining the harmonic components of time series 72 TABLE 1. ...
