AbstractAbstract
[en] Motion of radioactive gas through a one-dimensional homogeneous layer of porous medium of finite length is considered. The system of equations for motion of radioactive gas with regard to convective diffusion and adsorption is presented. The radioactive gas distribution in the flux at t1=20 s and t2=30 s time moments at the radioactive gas concentration fed to the input in the delta-function form, is demonstrated

AbstractAbstract
[en] Relations decreasing dependence of ionizing current on structural parameters and ionization rate are obtained on the basis of analysis of equations of drift and diffusion model for the short diode case with abrupt transition and recombination type constants. Analytical relations obtained for short diode case are shown to be limiting ones for a long diode. The suggested approach allows to calculate ionization and photoelectrical characteristics of structures with soft transition

AbstractAbstract
[en] The analytical solution of the problem of impurity diffusion in the irradiated plane-parallel semiconductor is found out using the method of the circuit integral. Fast diffusion processes with characteristic times considerably smaller than those of defect annealing was under study. The trap concentration was accepted to be constant with time. The statistic model of capture and release from traps was used under the assumption of homogenizing over traps. In a general case the solution is reduced to the expression of a diffusion type and has more complicated character demonstrating the dynamics of the process development

AbstractAbstract
[en] Technique and the results of calculation of distribution of energy losses of fast charged particles in oriented monocrystal are presented. Calculations are carried out for a narrow proton beam with pulses 15 GeV/c coming under different angles to (100) plane of a crystal and for a wide proton beam with 200 GeV energy coming along (110) plane of silicon. 3 refs.; 2 figs

AbstractAbstract
[en] Dynamics of fast charged particle beam rotation in a bended monocrystal is considered. Face and volume mechanisms of capture in channels are taken into account simultaneously in the model presented. Functions of distribution in transverse energies (φ) of channeled and dechanneled particles are obtained. Charge-energy ''scale invariance'' in ion channeling with charge Z in a bended crystal determined by scale parameter W=pv/Z (p and v are pulse and velocity local to transverse planes) follows from the model presented

AbstractAbstract
[en] The system of differential equations is obtained and solved which describes radioactive gas filtration taking into account condensation and nonequilibrium adsorption. The system solution has been obtained on assumption that condensate motion rate in a gas phase differs from the main gas flow motion rate. At the coincidence of these rates no saturation change (condensate fall-out into the liquid phase) is observed. This is what differs the results of the study of those earlier obtained

AbstractAbstract
[en] The information decomposition (ID) method to analyze symbolical sequences is presented. This method allows us to reveal a latent periodicity of any symbolical sequence. The ID method is shown to have advantages in comparison with application of the Fourier transformation, the wavelet transform and the dynamic programming method to look for latent periodicity. Examples of the latent periods for poetic texts, DNA sequences and amino acids are presented. Possible origin of a latent periodicity for different symbolical sequences is discussed

AbstractAbstract
[en] We consider a nonlinear ordinary differential equation having solutions with various movable pole order on the complex plane. We show that the pole order of exact solution is determined by values of parameters of the equation. Exact solutions in the form of the solitary waves for the second order nonlinear differential equation are found taking into account the method of the logistic function. Exact solutions of differential equations are discussed and analyzed
