Bulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2023 Summary: We study a mathematical model of coastal waves in the shallow water approximation. The model contains two empirical parameters. The first one controls turbulent dissipation. The second one is responsible for the turbulent viscosity and is determined by the turbulent Reynolds number. We study travelling waves solutions to this model.

Electrophoretic traveling waves [PDF]
Transactions of the American Mathematical Society, 1988 An existence-uniqueness-approximability theory is given for a prototypical mathematical model for the separation of ions in solution by an imposed electric field. The separation is accomplished during the formation of a traveling wave, and the mathematical problem consists in finding a traveling wave solution of a set of diffusion ...

Symmetric Waves Are Traveling Waves
International Mathematics Research Notices, 2009 We show that horizontally symmetric water waves are traveling waves. The result is valid for the Euler equations, and is based on a general principle that applies to a large class of nonlinear partial differential equations, including some of the most famous model equations for water waves. A detailed analysis is given for weak solutions of the Camassa-

Geometric Scaling as Traveling Waves [PDF]
Physical Review Letters, 2003 We show the relevance of the nonlinear Fisher and Kolmogorov-Petrovsky- Piscounov (KPP) equation to the problem of high energy evolution of the QCD amplitudes. We explain how the traveling wave solutions of this equation are related to geometric scaling, a phenomenon observed in deep-inelastic scattering experiments.

Turning the Stimulus On and Off Changes the Direction of α Traveling Waves
eNeuro, 2020 Visual Abstract Traveling waves have been studied to characterize the complex spatiotemporal dynamics of the brain. Several studies have suggested that the propagation direction of α traveling waves can be task dependent.

Active Traveling Wave in the Cochlea [PDF]
Physical Review Letters, 2003 A sound stimulus entering the inner ear excites a deformation of the basilar membrane which travels along the cochlea towards the apex. It is well established that this wavelike disturbance is amplified by an active system. Recently, it has been proposed that the active system consists of a set of self-tuned critical oscillators which automatically ...

Euler–Darboux–Poisson Equation in Context of the Traveling Waves in a Strongly Inhomogeneous Media
Mathematics, 2023 The existence of traveling waves in an inhomogeneous medium is a vital problem, the solution of which can help in modeling the wave propagation over long distances. Such waves can be storm waves or tsunami waves in the seas and oceans.

Traveling Waves and Superposition Exercise Set 1
, 2002 The top two panes display waves that are traveling simultaneously in the same medium (same string, spring, air column, etc). Note that the two waves are traveling at the same speed in opposite directions and that they have the same amplitude and ...

Classification of diagnostic features of transient signals in the electric power industry [PDF]
E3S Web of Conferences, 2021 Problems of practical implementation of traveling wave fault location caused by the registration of signals of different nature are considered. Analysis of the experimentally recorded traveling waves made it possible to divide them into 4 groups caused ...

Alpha oscillations and traveling waves: Signatures of predictive coding?
PLoS Biology, 2019 Predictive coding is a key mechanism to understand the computational processes underlying brain functioning: in a hierarchical network, higher levels predict the activity of lower levels, and the unexplained residuals (i.e., prediction errors) are passed
