Simple Implementations of the Cole-Cole Models

2020 2nd Novel Intelligent and Leading Emerging Sciences Conference (NILES), 2020
A novel procedure for the circuit implementation of the single and double dispersion Cole-Cole models is presented in this work. The concept is that the impedance of the whole model is approximated and implemented by appropriately configured RC networks, instead of the conventional implementation method where the approximation of each one of the ...

On the adequacy of identified Cole–Cole models

Computers & Geosciences, 2003
The Cole-Cole model has been widely used to interpret electrical geophysical data. Normally an iterative computer program is used to invert the frequency domain complex impedance data and simple error estimation is obtained from the squared difference of the measured (field) and calculated values over the full frequency range.

Cole-cole dispersion models for aqueous gelatin-syrup dielectric composites

IEEE Transactions on Geoscience and Remote Sensing, 2006
A dielectric composite is developed with permittivity ranging from 8 to 75 with selectable conductive and dielectric losses. The composite comprises gelatin, high fructose corn syrup (HFCS), NaCl, and water, and can be used to model soils, loams, and sands in the 200-MHz to 20-GHz range.

Extracting the Cole-Cole Model Parameters of Tissue-mimicking Materials

2018 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2018
Tissue mimicking materials are used as a safe alternative testing platform during the development of medical applications such as wearables devices and body area networks. Identifying the accurate electrical properties of the materials in use is important to guarantee accuracy and reproducibility of results. In this paper, we propose a novel extraction

AN ANISOTROPIC COLE–COLE MODEL OF SEISMIC ATTENUATION

Journal of Computational Acoustics, 2002
A simple model of seismic wave attenuation combining anisotropy with anelastic effects is constructed. The anelastic response is based on the Cole–Cole relaxation function. Time-stepping finite-difference and ray-asymptotic methods of numerical solution are discussed.

Two-modal cole-cole modelling of lP time domain relaxations

53rd EAEG Meeting, 1991
The dominant method for detecting and delineating native pyrite mineralization is Induced Polarization (lP). In presence of hydrocarbon reservoirs the lP anomalies are thought to he caused by epigenetic pyritization located in a plume over oil fields in a geochemically active environment.

Interpolation of Induced Polarization Transients by the Generalized Cole-Cole Relaxation Model

1990
We consider a Generalized Cole-Cole (GCC) model as representative of relaxations of electric voltages in time domain Induced Polarization.

The cole-cole model of porcine activity tissues in radio frequency

2017 10th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2017
In this paper, the four-pole Cole-Cole model of porcine normal activity tissues in radio frequency band is presented in order to describe the dielectric properties of activity tissues for the simulation study. The measurements of activity tissues with 90% humidity at 34°C are achieved by the open-ended coaxial probe and network analyzer in the ...

Mechanical interpretation and generalization of the Cole-Cole model in viscoelasticity

GEOPHYSICS, 2018
The mechanical basis of the popular Cole-Cole rheological model in viscoelasticity is investigated by using Lagrangian mechanics with nonlinear energy dissipation. The Cole-Cole model is usually viewed as a convenient way to fit the observed frequency-dependent attenuation and velocity-dispersion spectra, but its time-domain and numerical formulations
