Inclusion of the frequency effect in the lumped parameters transmission line model: State space formulation
(2009-07-01)
The objective of this paper is to include the frequency dependence of the longitudinal parameters in the lumped parameters line model. The distributed nature of the transmission line was approximated by a cascade of π ...

Effect of soil structure interaction on the dynamic responses of base isolated bridges and comparison to experimental results
(Elsevier Ltd, 2018)
In this paper, the effect of soil structure interaction and base isolation on the dynamic characteristics of an instrumented bridge is examined using transfer functions and measured motions in the frequency domain. A three ...
Time-Domain Electromechanical Impedance for Structural Health Monitoring
(European Assoc Structural Dynamics, 2011-01-01)
Electromechanical impedance (EMI) technique is a very simple method that can be usefulness in most of Non-Destructive Evaluation (NDE) and Structural Health Monitoring (SHM) systems. A common application of EMI methods is ...

Analysis of the Frequency Dependent Lumped Parameter Transmission Line Model
(2020-11-12)
An accurate transmission line model must consider the frequency-dependence of the longitudinal parameters. In this context, the lumped parameter model (LPM), despite its well-known limitations, had been largely used to ...
Using circuit elements to represent the distributed parameters of a grounding systems under lightning strokes
(Ieee, 2017-01-01)
This work presents a proposal to represent electrical grounding systems directly in the time domain. The advantage in using this type of representation is that voltage and current are better understood in this domain and ...

Analyses of the Spurious Oscillations in the Lumped Parameters Line Model
(Ieee-inst Electrical Electronics Engineers Inc, 2015-07-01)
The currents and voltages in the multiphase transmission line are described by differential equations that sometimes can be difficult to solve due the mutual coupling and skin effect that have to be considered for accurate ...
