One of the mechanisms of energy transfer between degrees of freedom of dusty plasma system can be described by equations similar to Mathieu equation with account of stochastic forces. Such equation is studied by analytical approach. The solutions for higher order of accuracy are obtained. The method for numerical solution and resonance zone detection is proposed. The solution for the extended Mathieu equation is obtained for wide range of parameter values. The results of numerical solution are compared with analytical solutions of different order and known analytical results for Mathieu equation.

Dust particles in plasma may have different values of average kinetic energy for
vertical and horizontal motion. The partial equilibrium of the subsystems and the relaxation
processes leading to this asymmetry are under consideration. A method for the relaxation time
estimation in nonideal dusty plasma is suggested. The characteristic relaxation times of vertical
and horizontal motion of dust particles ...

The molecular dynamics method is used for studying the effect of forces acting in a dusty plasma and discharge parameters on the mean interparticle distance in structures in a dc glow discharge in the temperature range 50–300 K. We report on the results of the dependence of the mean interparticle distance on the neutral gas ...

The self-consistency and basic openness of dusty plasma, charge fluctuations, high
dissipation and other features of dusty plasma system lead to the appearance of a number
of unusual and unique properties of dusty plasma. “Anomalous” heating of dusty particles,
anisotropy of temperatures and other features, parametric resonance, charge fluctuations
and interaction potential are among these unique properties. Study is ...

It is often suggested that inter-particle distance in stable dusty plasma structures decreases with cooling as a square root of neutral gas temperature. Deviations from this dependence (up to the increase at cryogenic temperatures) found in the experimental results for the pressures range 0.1–8.0 mbar and for the currents range 0.1–1.0 mA are given. Inter-particle ...

Viscosity and diffusion are chosen as an example to demonstrate the universality of diagnostics methods in the molecular dynamics method. To emphasize the universality, three diverse systems are investigated, which differ from each other drastically: liquids with embedded atom method and pairwise interatomic interaction potentials and dusty plasma with a unique multiparametric interparticle interaction potential. ...

Dust particles under certain conditions can acquire kinetic energy of the order of
10 eV and higher, far above the temperature of gas and temperatures of ions and electrons in the
discharge. Such heating can be explained by the energy transfer between degrees of freedom of
a dusty plasma system. One of the mechanisms of such energy transfer ...

Particles interaction and value of the screening length in dusty plasma systems
are of great interest in dusty plasma area. Three inter-particle potentials (Debye potential,
Gurevich potential and interaction potential in the weakly collisional regime) are used to solve
equilibrium equations for two dusty particles suspended in a parabolic trap. The inter-particle
distance dependence on screening length, trap parameter ...

A general approach to measure statistical uncertainty of different filtration techniques for market network analysis is proposed. Two measures of statistical uncertainty are introduced and discussed. One is based on conditional risk for multiple decision statistical procedures and another one is based on average fraction of errors. It is shown that for some important cases ...

Text encodings from automatic speech recognition (ASR) transcripts and audio representations have shown promise in speech emotion recognition (SER) ever since. Yet, it is challenging to explain the effect of each information stream on the SER systems. Further, more clarification is required for analysing the impact of ASR's word error rate (WER) on linguistic emotion ...

Motivated by a problem arising when analysing data from quarantine searches, we explore properties of distributions of sums of independent means of independent lattice-valued random variables. The aim is to determine the extent to which approximations to those sums require continuity corrections. We show that, in cases where there are only two different means, the ...
