Minimal model for tidal bore revisited

New Journal of Physics, 2019
This develops a recent analysis of gentle undular tidal bores (2018 New J. Phys. 20 053066) and corrects an error. The simplest linear-wave superposition, of monochromatic waves propagating according to the shallow-water dispersion relation, leads to a ...

Relaxation Oscillations in a System with Delays Modeling the Predator-Prey Problem

Моделирование и анализ информационных систем, 2013
A new asymptotic method for investigating complex relaxation oscillations of a system with delay was offered. Applying it, we can reduce the problem of predator-prey system dynamics to problem of one-dimensional maps analysis.

Asymptotic Quasinormal Frequencies of Different Spin Fields in Spherically Symmetric Black Holes [PDF]

, 2005
We consider the asymptotic quasinormal frequencies of various spin fields in Schwarzschild and Reissner-Nordstr\"om black holes. In the Schwarzschild case, the real part of the asymptotic frequency is ln3 for the spin 0 and the spin 2 fields, while for ...

Meanders: exact asymptotics [PDF]

Nuclear Physics B, 2000
We conjecture that meanders are governed by the gravitational version of a c=-4 two-dimensional conformal field theory, allowing for exact predictions for the meander configuration exponent =\sqrt{29}(\sqrt{29}+\sqrt{5})/12, and the semi-meander exponent {\bar }=1+\sqrt{11}(\sqrt{29}+\sqrt{5})/24.

On the Diophantine Equation z(n) = (2 − 1/k)n Involving the Order of Appearance in the Fibonacci Sequence

Mathematics, 2020
Let ( F n ) n ≥ 0 be the sequence of the Fibonacci numbers. The order (or rank) of appearance z ( n ) of a positive integer n is defined as the smallest positive integer m such that n divides F m .

Full Waveform Inversion Based on an Asymptotic Solution of Helmholtz Equation

Geosciences, 2023
This study considers the full waveform inversion (FWI) method based on the asymptotic solution of the Helmholtz equation. We provide frequency-dependent ray tracing to obtain the wave field used to compute the FWI gradient and calculate the modeled data.

The Exponentiated Power Alpha Index Generalized Family of Distributions: Properties and Applications

Mathematics, 2023
The study of hydrological characteristics has a vital role in designing, planning, and managing water resources. The selection of appropriate probability distributions and methods of estimations are basic elements in hydrology analyses.

Asymptotic Capture-Number and Island-Size Distributions for One-Dimensional Irreversible Submonolayer Growth

, 2003
Using a set of evolution equations [J.G. Amar {\it et al}, Phys. Rev. Lett. {\bf 86}, 3092 (2001)] for the average gap-size between islands, we calculate analytically the asymptotic scaled capture-number distribution (CND) for one-dimensional ...

Dynamics of Dollard asymptotic variables. Asymptotic fields in Coulomb scattering [PDF]

, 2016
Generalizing Dollard's strategy, we investigate the structure of the scattering theory associated to any large time reference dynamics $U_D(t)$ allowing for the existence of M{\o}ller operators.

Discrete asymptotic nets and W-congruences in Plucker line geometry

, 2000
The asymptotic lattices and their transformations are studied within the line geometry approach. It is shown that the discrete asymptotic nets are represented by isotropic congruences in the Plucker quadric.
