Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... Here we present the ionospheric parameters variations for quiet conditions. ...

... The operators will be explained as they are used. The general notion to keep in mind is that any combination of these operators results in a 2- D affine coordinate transformation in the TF plane, which may be represented using the homogeneous coordinates often used in computer graphicsfoley. ... S _t_c,f_c = g_t_c,f_c,(_t) | ... We denote a time shift to the position , with an operator that has a multiplicative law of composition : (Table 1). ... Note that these two operators do not commute. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...

The beam pattern and the polarization characteristics . of the radio telescope RATAN-600 . The Mueller matrix elements was computed via formulas [1]: . ... The BP were computed by the aperture method, proceeding from the fild distribution in the aperture of the primary mirror. The components of the main and cross-polarization components of the electric field in the vertical aperture of the primary mirror was computed in Frenel diffraction approximation. ...

... The Boolean object is an object wrapper for a boolean value. ... JavaScript 1.3: added toSource method . ... If value is omitted or is 0, -0, null, false, NaN , undefined, or the empty string ( "" ), the object has an initial value of false. All other values, including any object or the string "false" , create an object with an initial value of true. ... For Boolean objects and values, the built-in toString method returns the string "true" or "false" depending on the value of the boolean object. ...

THE PARAMETERS INVOLVED IN HAPKE'S MODEL FOR ESTIMATION OF THE COMPOSITION OF THE EJECTA LUNAR TERRAINS. ... In the previous papers we were estimated the surface roughness of the ejecta lunar terrains by means comparison of the local phase function and the average integrated lunar indicatrix. ... The Hapke's theoretical model of the lunar surface reflection. ... For THE PARAMETERS INVOLVED IN HAPKE'S MODEL: S.G. Pugacheva, V.V. Shevchenko a low-albedo lunar surface parameter Bo = 1. ...

Hideyuki Saio Simon Jeffery are exploring models for the evolution of stars formed by the merger of two white dwarfs. The attached movie provides a simulation of the major events involved in the merger process. ... An initial binary system consists of two white dwarfs of masses M 1 and M 2 (given) with an orbital period ( P ). ... We adopt a simple expression for the white dwarf radius as a function of mass (in solar units): . ... The merged star evolution is simulated by a quadratic expansion . ...
