The concept of vibration damping of the variable mass assembly

MATEC Web of Conferences, 2019
An innovative method of damping vibrations using a variable mass assembly will be presented in this article. The concept was based on a physical pendulum model consisting of two connected elements.

Blow-up solutions with minimal mass for nonlinear Schrödinger equation with variable potential

Advances in Nonlinear Analysis, 2021
This paper studies the mass-critical variable coefficient nonlinear Schrödinger equation. We first get the existence of the ground state by solving a minimization problem.

Coupled oscillators with variable mass

Journal of Physics: Conference Series, 2022
Abstract In this work the problem of two containers with variable mass coupled and aligned by springs is studied. The containers are filled with granular mass that lose at a constant rate. Once the containers have been emptied, the classic problem of coupled oscillators with constant mass is recovered.

Nucleosynthesis in thermonuclear supernovae with tracers: convergence and variable mass particles

, 2010
Nucleosynthetic yield predictions for multi-dimensional simulations of thermonuclear supernovae generally rely on the tracer particle method to obtain isotopic information of the ejected material for a given supernova simulation.

Predictions of variable mass loss for Luminous Blue Variables [PDF]

, 2002
We present radiation-driven wind models for Luminous Blue Variables (LBVs) and predict their mass-loss rates. We study the effects of lower masses and modified abundances in comparison to the normal OB supergiants, and we find that the main difference in

Perturbation Methods in Solving the Problem of Two Bodies of Variable Masses with Application of Computer Algebra

Applied Sciences
The classical many-body problem is not integrable, so perturbation theory based on an exact solution to the two-body problem is usually applied to investigate the dynamics of planetary systems.

Analysis of Cattaneo-Christov heat and mass fluxes in the squeezed flow embedded in porous medium with variable mass diffusivity

Results in Physics, 2017
This research article investigates the squeezing flow of Newtonian fluid with variable viscosity over a stretchable sheet inserted in Darcy porous medium. Cattaneo-Christov double diffusion models are implemented to scrutinize the characteristics of heat
