Influence of hard alloys CEDG modes on the size of dissolved layer

open access: yesMATEC Web of Conferences, 2018
Correctly assigned technological modes of processing define the accuracy of forming, optimum mechanical and electrochemical speed of the processed material removal, quality and durability of the cutting tool as well as provide the self-sharpening ...

BroadBand-Adaptive VMD with Flattest Response

open access: yesMathematics, 2023
A mixed signal with several unknown modes is common in the industry and is hard to decompose. Variational Mode Decomposition (VMD) was proposed to decompose a signal into several amplitude-modulated modes in 2014, which overcame the limitations of ...

Small x divergences in a heavy quark-antiquark state [PDF]

open access: yes, 2001
With the current state of similarity renormalisation group approach to light-front QCD, it is possible to address with a degree of generality the issue of light-cone zero modes.

A model of the effect of collisions on QCD plasma instabilities

open access: yes, 2006
We study the effect of including a BGK collisional kernel on the collective modes of a QCD plasma which has a hard-particle distribution function which is anisotropic in momentum space.

Collective Dynamics in Quasi-One-Dimensional Hard Disk System

open access: yesFrontiers in Physics, 2021
We present the results of molecular dynamic studies of collective dynamics in a system of hard disks confined to a narrow quasi-one-dimensional (quasi-1D) channel. The computer simulations have been performed for the specific channel width of 3/2 of disk

Stability of Nonlinear Normal Modes in the FPU-$\beta$ Chain in the Thermodynamic Limit

open access: yes, 2011
All possible symmetry-determined nonlinear normal modes (also called by simple periodic orbits, one-mode solutions etc.) in both hard and soft Fermi-Pasta-Ulam-$\beta$ chains are discussed.

Time-dependent mode structure for Lyapunov vectors as a collective movement in quasi-one-dimensional systems

open access: yes, 2004
Time dependent mode structure for the Lyapunov vectors associated with the stepwise structure of the Lyapunov spectra and its relation to the momentum auto-correlation function are discussed in quasi-one-dimensional many-hard-disk systems. We demonstrate
