We reexamine stochastic Fermi acceleration (STFA) in the low energy (Newtonian) regime in the context of solar flares. The particle energization rate depends a dispersive term and a coherent gain term. The energy dependence of pitch angle scattering is important for determining the electron energy spectrum. For scattering by whistler wave turbulence, STFA produces a quasi-thermal spectrum. A se...

Abstract We consider the acceleration of charged particles in relativistic shearing flows, with Lorentz factor up to ? 0 ? 20. present numerical solutions particle transport equation and compare these results from analytical calculations. show that highly limit energy spectrum approaches a power law, <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathM...

Background and objective: numerous seismic hazard analysis studies are conducted annually using probabilistic methods throughout the world and Iran, which are usually different from the initial assumptions of analysis or software used. On the other hand, many researches are presented every year about new methods of earthquake hazard zoning, but so far these studies have not computed earthquake ...

The paper is devoted to a numerical study of the problem interaction wave packet with potential structures moving constant acceleration. In all cases considered result change in velocity spectrum. first approximation magnitude shift spectrum determined by product acceleration group delay time. Also, as direction reverses effect changes its sign. results are completely consistent idea universali...

contrary to the long period ground motions that can be predicted and estimated, high frequency ground motions have random character and behave stochastically. stochastic modeling methods are usually used for the modeling of high frequency ground motions where there are not strong ground motion records. stochastic methods are of two kinds: in the first one, the seismic source is considered as a ...
