Quasi-contiguous approximation for line-shape modeling in plasmas
نویسندگان
چکیده
We present an analytical method for the calculation of shapes of Stark-broadened spectral lines in plasmas, applicable to hydrogen and hydrogen-like transitions (including Rydberg ones). The method is based on the recently suggested quasi-contiguous approximation of the static Stark line shapes [E. Stambulchik, and Y. Maron, J. Phys. B: At. Mol. Opt. Phys. 41, 095703 (2008)], while the dynamical effects are accounted for using the frequency-fluctuation-model approach. Comparisons with accurate computer simulations show excellent agreement.

A Free Line Search Steepest Descent Method for Solving Unconstrained Optimization Problems
In this paper, we solve unconstrained optimization problem using a free line search steepest descent method. First, we propose a double parameter scaled quasi Newton formula for calculating an approximation of the Hessian matrix. The approximation obtained from this formula is a positive definite matrix that is satisfied in the standard secant relation. We also show that the largest eigen value...
متن کاملIdeal Coulomb Plasma Approximation in Line Shape Models: Problematic Issues
In weakly coupled plasmas, it is common to describe the microfield using a Debye model. We examine here an “artificial” ideal one-component plasma with an infinite Debye length, which has been used for the test of line shape codes. We show that the infinite Debye length assumption can lead to a misinterpretation of numerical simulations results, in particular regarding the convergence of calcul...

Biorthogonal wavelet-based full-approximation schemes are introduced in this paper for the numerical solution of elasto-hydrodynamic lubrication line and point contact problems. The proposed methods give higher accuracy in terms of better convergence with low computational time, which have been demonstrated through the illustrative problems.
متن کاملFluxon modeling of low-beta plasmas
We have developed a new, quasi-Lagrangian approach for numerical modeling of magnetohydrodynamics in low to moderate b plasmas such as the solar corona. We introduce the concept of a ‘‘fluxon’’, a discretized field line. Fluxon models represent the magnetic field as a skeleton of such discrete field lines, and interpolate field values from the geometry of the skeleton where needed, reversing th...
متن کاملSession Iib Multimedia Storage, Compression and Application Three-dimensional Shape Modeling with a Raster Scan Format
A simple and robust procedure of three-dimensional shape modeling for an object approximation has been developed based on a raster scan modeling algorithm. A prototypical surface or solid model with desired meshing is first prepared and then transferred to the model that approximates the shape of the real object. The vertex geometry of the prototypical mesh is modified based on the multi-direct...
