Analytical solution for dynamic interaction of end-bearing pile groups subjected to vertical dynamic loads

open access: yesYantu gongcheng xuebao, 2022
An analytical model for pile-soil-vertical coupled vibration of the pile considering the scattering effects of the passive pile is proposed based on the classical plane strain assumption.

First-principles study of the thermal transport properties of superconducting NbN [PDF]

open access: yesE3S Web of Conferences, 2023
We investigate the thermal transport properties of NbN by considering three-phonon scattering (3ph), four-phonon scattering (4ph), electron-phonon (ep) scattering, and isotope (iso) scattering.

Comparison Failure and Successful Methodologies for Diffusion Measurements Undertaken inside Two Different Testing Rooms

open access: yesApplied Sciences, 2021
The scattering phenomenon is known to be of great importance for the acoustic quality of a performance arts space. The scattering of sound can be achieved in different ways: it can be obtained by the presence of architectural and/or decorating elements ...

Modelling the Acoustic Propagation in a Test Section of a Cavitation Tunnel: Scattering Issues of the Acoustic Source

open access: yesModelling, 2023
The prediction of the underwater-radiated noise for a vessel is classically performed at a model scale and extrapolated by semi-empirical laws. The accuracy of such a method depends on many parameters.

Decoherence effects in reactive scattering [PDF]

open access: yesThe Journal of Chemical Physics, 2005
Decoherence effects on quantum and classical dynamics in reactive scattering are examined using a Caldeira–Leggett type model. Through a study of the dynamics of the collinear H+H2 reaction and the transmission over simple one-dimensional barrier potentials, we show that decoherence leads to improved agreement between quantum and classical reactions ...
