The features of the interaction between internal solitary waves are investigated within
the framework of the completely integrable Gardner equation with positive cubic nonlinearity. It is
shown that the soliton polarity affects radically the result of the interaction between the solitons.
The role of the pair interactions between solitons of different polarities proceeding when rogue waves
emerge in the soliton fields in a stratified basin is demonstrated. The effect of such interactions on
the higher-order moments of the wave field is studied.

We study the statistical moments of the soliton gas (mean field, variance, skewness, and kurtosis),
which is described within the framework of the Gardner equation with negative cubic nonlinearity.
The influence of the limiting (thick or table-like) soliton on the statistical moments of the soliton
gas is considered. It is shown to be substantial if the thick-soliton intensity ...

The article presents the results of numerical simulation of the dynamics of solitary internal waves’ ensembles in a stratified (vertically inhomogeneous) ocean for hydrophysical conditions close to those on the Indian Ocean shelf. Ensembles of unipolar and bipolar solitons, as well as solitons and breathers with random amplitudes and phases are considerate. Estimates of the statistical characteristics of ...

Oscillating wave packets (breathers) are a significant part of the dynamics of internal gravity
waves in a stratified ocean. The formation of these waves can be provoked, in particular, by the decay
of long internal tidal waves. Breather interactions can significantly change the dynamics of the wave
fields. In the present study, a series of numerical experiments on ...

Приведена физико-математическая модель трансформации двумерных нелинейных внутренних волн в природных стратифицированных водоемах. Модель основана на уравнении Кортевега-де Вриза и его обобщениях. Коэффициенты этого уравнения вычисляются по известным вертикальным распределениям плотности жидкости с помощью решения задачи Штурма-Лиувилля на собственные значения. Модель учитывает горизонтальную изменчивость гидрологических полей по горизонтали и переменность глубины водоема. В качестве примера рассмотрена трансформация ...

In the present paper, we study phase waves of self-sustained oscillators with a nearest-neighbor dispersive coupling on an infinite lattice. To analyze the underlying dynamics, we approximate the lattice with a quasi-continuum (QC). The resulting partial differential model is then further reduced to the Gardner equation, which predicts many properties of the underlying solitary structures. ...

We study the two-soliton interaction dynamics within the framework of a fully integrable model,
i.e., the Gardner equation with negative cubic nonlinearity, which admits the existence of a limiting
soliton. The features of the soliton interaction with participation of a thick soliton are demonstrated.
Special attention is paid to the nonlinear-interaction influence on the moments of the wave ...

Work solutions are proposed for problems of leader definition and role distribution in homogeneous groups of robots. It is shown that transition from a swarm to a collective of robots with hierarchical organization is possible using exclusively local interaction. The local revoting algorithm is central to the procedure for choice of leader while redistribution of roles can ...

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 ...
