Modal and flutter analysis of the sailplane LAK-17B using numerical methods

open access: yesTransport, 2014
The objective of current work is to determine the V–g and V–f diagrams for the sailplane’s LAK-17B empennage using numerical methods. The article considers the following problems: development of finite element model of the sailplane LAK-17B; normal modes

Normal modes for two-dimensional gravitating kinks

open access: yesPhysics Letters B, 2022
We study small perturbations around an arbitrary static kink solution of a two-dimensional (2D) gravity-scalar system, where the gravity part is described by a subclass of 2D dilaton gravity theory, and the scalar matter field has generalized dynamics ...

Nonlinear quasi-normal modes: uniform approximation

open access: yesJournal of High Energy Physics, 2023
Recent works have suggested that nonlinear (quadratic) effects in black hole perturbation theory may be important for describing a black hole ringdown.

Normal-Mode–Vortex Interactions [PDF]

open access: yesPhysical Review Letters, 2002
Standing surface waves that interact with a confined, vertical, vorticity field with zero net circulation are studied both analytically and experimentally. The surface waves are generated by vertical vibration, and constant vorticity injection is achieved by a rotating disk flush mounted in the cell.

A Novel Finite Difference Scheme for Normal Mode Models in Underwater Acoustics

open access: yesJournal of Marine Science and Engineering, 2023
Normal mode models are commonly used to simulate sound propagation problems in horizontally stratified oceanic environments. Although several normal mode models have been developed, the fundamental techniques for accurately and efficiently solving the ...

Solar flares with sustained gamma-ray emission and some characteristics of high-energy proton fluxes

open access: yesSolar-Terrestrial Physics, 2023
The first part of the work presents the results of numerical experiments with the magnetohydrodynamic model of “shallow water” to assess the degree of influence of the magnetic field on the development of instabilities conditioned by a combination of ...

Normal Modes and Essential Dynamics

open access: yes, 2008
Normal mode analysis and essential dynamics analysis are powerful methods used for the analysis of collective motions in biomolecules. Their application has led to an appreciation of the importance of protein dynamics in function and the relationship between structure and dynamical behavior.

Estimating Sound Exposure Levels Due to a Broadband Source over Large Areas of Shallow Sea

open access: yesJournal of Marine Science and Engineering, 2022
3D sound propagation modeling in the context of acoustic noise monitoring problems is considered. A technique of effective source spectrum reconstruction from a reference single-hydrophone measurement is discussed, and the procedure of simulation of ...
