NUMERICAL SIMULATION OF MULTICOMPONENT ION BEAM DYNAMICS IN TRANSPORTATION LINES (2009)
V. Alex, N. Kazarinov, V. Mironov, V. Shevtsov, G. Shirkov
A new version of a program library for numerical simulation of ion beam transportation is presented. The library is aimed for simulation of high current and low energy multicomponent beams extracted...
PARTICLE-IN-CELL NUMERICAL SIMULATIONS OF PARTICLE DYNAMICS IN BEAMS AND ECR SOURCES (2008)
G. Shirkov, V. Alex, V. Shevtsov
Finite particle methods allow studying the detailed beam and plasma characteristics, the distribution function of particles, the nonlinear self and external fields. A particle-in-cell method is one...
Parallel resolvent Monte Carlo algorithms for linear algebra problems (2008)
I. Dimov A, V. Alex, Rov B, A. Karaivanova A
In this paper we consider Monte Carlo (MC) algorithms based on the use of the resolvent matrix for solving linear algebraic problems. Estimates for the speedup and efficiency of the algorithms are...

controversy. The tension between production and preservation continues and hampers current negotiations for a code of practice for private native forestry. The structure of many private forests...
Reinig, P., Selle, B., Fenske, F., Fuhs, W., Alex, V., Birkholz, M.
Nominally undoped polycrystalline silicon (poly-Si) thin films were deposited on glass at 450 deg C at high deposition rate (>100 nm/min) by pulsed dc magnetron sputtering. The pulse frequency was...
