Railway lines models for impedance evaluation

8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002
This paper deals with modeling of electrified railway lines using the multiconductor transmission lines (MTLs) approach, in order to investigate the harmonic impedance seen at the train pantograph at various locations along the line. A railway line model has been studied and a sensitivity analysis with respect to the structure of the model has been ...

Beam Measurements of the LHC Impedance and Validation of the Impedance Model

2014
Different measurements of the longitudinal impedance of the LHC done with single bunches with various intensities and longitudinal emittances during measurement sessions in 2011-2012 are compared with particle simulations based on the existing LHC impedance model.

Impedance modelling of pipes

European Journal of Physics, 2015
Impedance models of pipes can be used to estimate resonant frequencies of standing waves and model acoustic pressure of closed and open ended pipes. Modelling a pipe with impedance methods allows additional variations to the pipe to be included in the overall model as a system.

Modelling impedance for 3D impedimetric biosensor

2015 9th International Conference on Sensing Technology (ICST), 2015
There is a growing need for new biosensing technologies that are more rapid and convenient to use for onsite sensing. Impedance-based electrochemical sensor is a promising candidate due to simplicity of its sensing mechanism. However, like other emerging biosensors, specificity, sensitivity, and reliability are major obstacles that limit their use in ...

Electrode Modelling in Electrical Impedance Tomography

SIAM Journal on Applied Mathematics, 1992
Summary: In electrical impedance tomography, measurements of an applied electrical current and the corresponding electrical potential are made on a finite number of electrodes placed on the boundary of an object. These measurements are then used to reconstruct the electrical conductivity distribution in the interior of the object.

Modeling of low-frequency pulmonary impedance in dogs [PDF]

open access: possibleJournal of Applied Physiology, 1990
The mechanical impedance of the lungs (ZL) was measured in open-chest dogs with small-amplitude pseudorandom volume oscillations between 0.125 and 5 Hz, at mean transpulmonary pressures (Ptp) of 0.2, 0.4, and 0.8 kPa. At the lowest frequencies, the pulmonary resistance showed a marked negative frequency dependence and mirrored the changes in the ...

(Keynote) Modeling of Impedance

ECS Meeting Abstracts, 2016
Sophisticated models exist for many electrochemical systems, based on physical and chemical laws.  These may be transient or steady.  They generally involve many physical quantities, and a corresponding number of governing equations, distributed over a spatial region.

The Proton Synchrotron Transverse impedance model

2014
The current knowledge of the transverse impedance of the CERN Proton Synchrotron (PS) has been established by theoretical computations, electromagnetic simulations and beam-based measurements at different energies. The transverse coherent tune and phase advance shifts as a function of intensity have been measured in order to evaluate the total ...

Instantaneous model impedance control for robots

Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002
We propose a new method for implementing impedance control, which is designed to take advantage of the error-correction capabilities of position controllers, while maintaining good impedance tracking performance. The proposed instantaneous model impedance control re-initializes the impedance model to the current position of the robot so the model does ...
