An Integrated Nonlinear Analysis (INA) Software for Space Plasma Turbulence
Echim, Marius; Munteanu, Costel; Kovács, Péter
We built an integrated nonlinear analysis software (INA)-designed to study space plasma turbulence and intermittency. The MATLAB programming environment was used for the algorithmic development and implementation of methods for spectral analysis, multiscale fluctuations and multifractal analysis. The performance of INA is demonstrated using magnet…
FPGA Design for On-Board Measurement of Intermittency From In-Situ Satellite Data
Echim, M. M.; Teodorescu, E.; Deak, N. +2 more
Intermittency is a fundamental property of space plasma dynamics, characterizing turbulent dynamical variables as well as passive scalars. Its qualitative and quantitative description from in-situ data requires an accurate estimation of the probability density functions (PDFs) of fluctuations and their moments, particularly the flatness, a normali…
Open-Source Software Analysis Tool to Investigate Space Plasma Turbulence and Nonlinear DYNamics (ODYN)
Echim, M. M.; Teodorescu, E.
We have designed and built a versatile modularized software library—ODYN—that wraps a comprehensive set of advanced data analysis methods meant to facilitate the study of turbulence, nonlinear dynamics, and complexity in space plasmas. The Python programming language is used for the algorithmic implementation of models and methods devised to under…
