The observation of dust in the rings Saturn by instruments on board Voyager 1, 2, and Cassini missions triggered our interest exploring evolution electrostatic acoustic waves (DAWs) Saturnian magnetospheric dusty plasma. salient features dust-acoustic solitary have been examined means numerical simulations that adopted a fluid algorithm. We considered highly energetic non-Maxwellian ion electro...

A linear stability analysis of ion-acoustic and dust-acoustic waves is carried out using a multifluid model in the presence of ionization, ion drag, and collisions of ions and dust with the background neutral gas. It is found that an unstable dust-acoustic mode of nonzero real frequency can be generated via a resonance phenomenon. This resonance develops as the frequency of the dust-ion-acousti...

The passage of an ion-acoustic solitary wave through the boundary between electron-ion plasma and a negative ion is considered. After enters region another plasma, disturbance arises, from which chain oscillations form over time. amplitude after changes in such way that its value greater than plasmas. An exception case compressive propagating having exceeding critical plasma. Such wave, when en...

This paper is concerned with the system of Zakharov equations which involves the interactions between Langmuir and ion-acoustic waves in plasma. Abundant explicit and exact solutions of the system of Zakharov equations are derived uniformly by using the first integral method. These exact solutions are include that of the solitary wave solutions of bell-type for n and E, the solitary wave soluti...

Dust acoustic waves (DAW) are spontaneously excited in dusty plasmas produced in dc and rf discharge plasmas over a wide range of plasma and dust conditions. A common feature of these plasmas is the presence of an ion drift relative to the dust, which is driven by an electric field, Eo in the discharge. Using a three fluid model of the DAWs, including the zero order electric field and collision...

Dust ion-acoustic shocks in a Q machine device are considered. For their description the so-called hydrodynamic ionization source model is used. The model is appropriate for the description of the laboratory experiments in a Q machine device and contains the most important basic mechanisms responsible for the formation of the dust ion-acoustic shocks. A comparative analysis of various dissipati...

EEG signals are records of nonlinear solitary waves in human brains. The waves have several types (e.g., α, β, γ, θ, δ) in response to different levels of consciousness. They are classified into two groups: Group-1 consists of complex storm-like waves (α, β, and γ); Group-2 is composed of simple quasilinear waves (θ and δ). In order to elucidate the mechanism of EEG wave formation and propagati...
