The use of first-principles based models of plasma processes is discussed in this paper. Such processes are essentially highly nonlinear, feature complex interactions and are difficult to analyse. As an illustration of the nature of firstprinciple based models, a characterisation of a simple plasma process is presented in this work. Quantification of the nonlinearity, in terms of steady-state a...

The multi-species plasma of natural or laboratory origin is often considered to host nonlinear ion-acoustic waves. We present calculations ion fluxes induced by waves in a consisting multiple populations, electrons, and dust. following models are considered: an electron-ion with cold ions, bi-ion two types warm positively charged dusty plasma. It found that the plasma, wave-induced flux directe...

We have developed a time-dependent three-dimensional model of isotropic, adiabatic, and compressible magnetohydrodynamic plasma to understand nonlinear cascades of density fluctuations in local interstellar medium. Our simulations, describing evolution of initial supersonic, super Alfvénic plasma modes, indicate that nonlinear interactions lead to damping of plasma motion. During the process, t...

Based on quantum hydrodynamics theory (QHD), the propagation of nonlinear quantum dust-ion acoustic (QDIA) solitary waves in a ‎collision-less, unmagnetized four component quantum plasma consisting of electrons, positrons, ions and stationary negatively charged ‎dust grains with dust charge variation is investigated using reductive perturbation method. The charging current to the dust grains ca...

The article describes the features of organizing a competently oriented educational process university, showing its strengths and weaknesses. nonlinear management organizations construction are described. Higher education development in Russia is proposed. importance personality students, formation professionally significant traits indicated. data survey (attitude students to existing process) ...

  Nonlinear Dust lattice modes are studied in a hexagonal two-dimensional dusty plasma lattice, in presence of charge gradient of dust particles. In this lattice, such gradients affect nonlinear behavior of dust lattice waves. The amplitude modulation of off-plane transverse dust lattice wave packets is investigated considering the anisotropy of interactions, caused by the height-dependent char...
