Feasibility of Sectional Bioelectrical Impedance Spectrum Evaluating Joint Effusion in Rat

open access: yesIEEE Access, 2020
Background: Joint effusion is a significant cause of disability worldwide. Practical assessment and diagnosis can avoid the secondary damage caused by the effusion. Nowadays, bioimpedance spectroscopy (BIS) is an emerging tool to differentiate biological

ES-MDA Method for Inverting SIP Data Based on Cole-cole Model Parameters

open access: yesJournal of Physics: Conference Series, 2023
Abstract SIP reflects the characteristics of charge storage in underground media. IP parameters such as polarizability and relaxation time are correlated with minerals, pores and other physical properties of rocks, so when establishing the relationship between SIP and other petrophysical parameters, it is necessary to accurately estimate

Parameter Identification for a New Circuit Model Aimed to Predict Body Water Volume

open access: yesAdvances in Electrical and Computer Engineering, 2012
Intracellular and extracellular water volumes in the human body have been computed using a sequence of models starting with a linear first order RC circuit (Cole model) and finishing with the De Lorenzo model. This last model employs a fractional order

Fractional calculus model of electrical impedance applied to human skin. [PDF]

open access: yesPLoS ONE, 2013
Fractional calculus is a mathematical approach dealing with derivatives and integrals of arbitrary and complex orders. Therefore, it adds a new dimension to understand and describe basic nature and behavior of complex systems in an improved way.

Bioelectrical Impedance Analysis of Capacitance and Inductance Effects Using Multisim Circuit Simulation

open access: yesJournal of Engineering
Bioelectrical impedance analysis (BIA) is a widely used method for estimating body composition, particularly body fat and muscle mass. It works by passing a weak electric current through the body and measuring the resulting voltage to calculate the body ...

Re-parameterization of the Cole-Cole Model for Improved Spectral Inversion of Induced Polarization Data

open access: yesProceedings, 2017
ABSTRACTThe induced polarization phenomenon, both in time domain and frequency domain, is often parameterised using the empirical Cole–Cole model. To improve the resolution of model parameters and to decrease the parameter correlations in the inversion process of induced polarization data, we suggest here three re‐parameterisations of the Cole–Cole ...

Realization of Cole–Davidson Function-Based Impedance Models: Application on Plant Tissues

open access: yesFractal and Fractional, 2020
The Cole–Davidson function is an efficient tool for describing the tissue behavior, but the conventional methods of approximation are not applicable due the form of this function.

Relationship between Cole–Cole model parameters in permittivity and conductivity formulation

open access: yesGeophysical Journal International
SUMMARY For the analysis of spectral induced polarization (SIP) measurements and for the description of frequency-dependent electrical relaxation responses, so-called Cole–Cole models (CCMs) are widely used. Typically, CCM formulations in terms of complex electrical conductivity or complex electrical resistivity are used in geophysical ...
