Mapping the Impedance Spectrum of Montague Model of Skin Impedance
2018 4th International Conference for Convergence in Technology (I2CT), 2018Transdermal drug delivery is a non-invasive method of drug administration. However to achieve this, drug has to pass through the complicated structure of skin. Complex structure of skin can be modeled by electrical equivalent circuit to calculate its impedance which is frequency dependent.

Modeling of respiratory system impedances in dogs
Journal of Applied Physiology, 1987Mechanical impedances between 4 and 64 Hz of the respiratory system in dogs have been reported (A.C. Jackson et al. J. Appl. Physiol. 57: 34–39, 1984) previously by this laboratory. It was observed that resistance (the real part of impedance) decreased slightly with frequency between 4 and 22 Hz then increased considerably with frequency above 22 Hz ...

Impedance modeling of modular multilevel converters
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015The impedance modeling of modular multilevel converters (MMCs) is a prerequisite for applying the impedance-based stability analysis method to an MMC-based high-voltage direct current (MMC-HVDC) transmission system. The objective of this paper is to develop impedance models of a three-phase MMC in order to assess its stability.

Broadband Time-Domain Impedance Models
AIAA Journal, 2001The modeling of a set of impedance values given either experimentally or heuristically for implementation as a time-domain impedance-equivalent boundary condition (TDIBC) is discussed. It is shown that impedance as defined by the reflection of plane harmonic waves when extended for broadband time-domain applications can correspond to mathematically ...

Radioengineering
Models of black anisotropic bodies are proposed, realized by a fine lattice of orthogonal impedance bands with generally variable orientation on the surface. Using flat surfaces and bodies of arbitrary shape as examples, it is shown that the impedance of a black anisotropic body is a complex quantity, the real part of which (resistance) can take both ...

Modelling respiratory impedance in patients with kyphoscoliosis
Biomedical Signal Processing and Control, 2014Abstract When a nonlinear biological system is under analysis, one may employ linear and nonlinear tools. Linear tools such as fractional order lumped impedance models have not been previously employed to characterize difference between healthy volunteers and patients diagnosed with kyphoscoliosis (KS).

Railway lines models for impedance evaluation
8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002This 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
2014Different 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 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), 2015There 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 ...
