Characterizing viscoelastic properties of human melanoma tissue using Prony series [PDF]
Frontiers in Bioengineering and Biotechnology, 2023 Melanoma is the most invasive and deadly skin cancer, which causes most of the deaths from skin cancer. It has been demonstrated that the mechanical properties of tumor tissue are significantly altered.

Interconversion of Prony series for relaxation and creep [PDF]
Journal of Rheology, 2015 Various algorithms have been proposed to solve the interconversion equation of linear viscoelasticity when Prony series are used for the relaxation and creep moduli, G(t) and J(t).

Fast-Acquiring High-Quality Prony Series Parameters of Asphalt Concrete through Viscoelastic Continuous Spectral Models. [PDF]
Materials (Basel), 2022 Prony series representations have been extensively applied to characterizing the time-domain linear viscoelastic (LVE) material functions for asphalt concrete. However, existing methods that can generate high-quality Prony series parameters (i.e., discrete spectra) mostly involve complicated programming algorithms, which poses a challenge for quick ...

Viscoelastic Relaxation Modulus Characterization Using Prony Series [PDF]
Latin American Journal of Solids and Structures, 2015 The mechanical behavior of viscoelastic materials is influenced, among other factors, by parameters like time and temperature. The present paper proposes a methodology for a thermorheologically and piezorheologically simple characterization of ...

Noise suppression in PD signal based on Prony time series energy spectrum [PDF]
IET Science, Measurement & Technology, 2022 On‐line partial discharge (PD) monitoring is related to the safe and stable operation of power grid. However, the measured signal is inevitably affected by noise. Among a variety of noises, white noise is the most difficult to suppress and ubiquitous. It

On the Prony series representation of stretched exponential relaxation [PDF]
Physica A: Statistical Mechanics and its Applications, 2018 Stretched exponential relaxation is a ubiquitous feature of homogeneous glasses. The stretched exponential decay function can be derived from the diffusion-trap model, which predicts certain critical values of the fractional stretching exponent. In practical implementations of glass relaxation models, it is computationally convenient to represent the ...

Известия Томского политехнического университета: Промышленная кибернетика, 2023 The Prony transform is considered in relation to recordings of electroencephalogram data. At the intermediate stage of the Prony transform, the roots of the polynomial are calculated, characterizing the frequency and attenuation of the signal under study.

Taylor series expansion and modified extended Prony analysis for localization [PDF]
Proceedings of 1994 28th Asilomar Conference on Signals, Systems and Computers, 2002 In the multiple source localization problem, many inverse routines use a rooting of a polynomial to determine the source locations. We present a rooting algorithm for locating an unknown number of three-dimensional, near-field, static sources from measurements at an arbitrarily spaced three-dimensional array. Since the sources are near-field and static,
