Time domain characterization of the Cole-Cole dielectric model

Journal of Electrical Bioimpedance, 2020
The Cole-Cole model for a dielectric is a generalization of the Debye relaxation model. The most familiar form is in the frequency domain and this manifests itself in a frequency dependent impedance.

Analogue Realization of Fractional-Order Dynamical Systems

Entropy, 2013
As it results from many research works, the majority of real dynamical objects are fractional-order systems, although in some types of systems the order is very close to integer order.

Fractional-Order Phase Shifters with Constant Magnitude Frequency Responses

Elektronika ir Elektrotechnika, 2019
This contribution presents and experimentally analyzes the idea how to reach the constant magnitude as well as the phase response in the fractional-order (FO) phase when shifting two-ports.

Computational analysis of contamination in Kojima Lake using upwind-type finite element method [PDF]

, 1998
We have computed the phase of spreading contaminations in Kojima Lake by using the upwind-type finite element method. We have treated the two cases: the pollutant flows from the Sasagase river and from the Kurashiki River.

Micromechanical response of fibre-reinforced materials using the boundary element technique [PDF]

, 2003
The Boundary Element Method (BEM) and the Embedded Cell Approach (ECA) have been used to analyse the effects of constituent material properties and fibre spatial distribution on the localised behaviour of a transversely loaded, unidirectional fibre ...

Impedance detection of the electrical resistivity of the wound tissue around deep brain stimulation electrodes permits registration of the encapsulation process in a rat model

Journal of Electrical Bioimpedance, 2017
An animal model of deep brain stimulation (DBS) was used in in vivo studies of the encapsulation process of custom-made platinum/iridium microelectrodes in the subthalamic nucleus of hemiparkinsonian rats via electrical impedance spectroscopy.
