Explicit form of relaxation tensor for isotropic extended Burgers model and its spectral inversion
Youjun Deng, Ching-Lung Lin, Gen Nakamura
Concerning the anelastic nature of Earth, the quasi-static extended Burgers model (abbreviated by q-EBM), an integro-differential system, is used to study the free oscillation of E…
Inverse Spectral Problem With Low Regularity Refractive Index
Kewen Bu, Youjun Deng, Yan Jiang +1
This article investigates the unique determination of a radial refractive index n from spectral data. First, we demonstrate that for piecewise twice continuously differentiable fun…
Inverse spectral problem for glassy state relaxation approximated by Prony series
Shuli Chen, Marrten V. de Hoop, Youjun Deng +2
The stretched exponential relaxation function is used to analyze the relaxation of the glassy state data. Due to the singularity of this function at the origin, this function is in…
Clustered eigenvalue problem for glassy state relaxation and its inverse problem
Shuli Chen, Maarten V. de Hoop, Youjun Deng +2
For computational convenience, a Prony series approximation of the stretched exponential relaxation function of homogeneous glasses has been proposed (J. Mauro, Y. Mauro, 2018), wh…
