A Grounding System Model Directly in Time-Domain
(2016-10-01)
This work presents a technique for electrical grounding system representation, directly in the time domain. It is based on the theory of least squares and starts from harmonic grounding impedance, representing it by discrete ...
A reduced order state space model for aeroelastic analysis in time domain
(2017-02-01)
The objective of this paper is to describe a new method for modeling aeroelastic system in time domain based on a modification of the Laguerre Polynomials to represent complex quantities. These polynomials are used to ...
Baseline-free Damage Imaging Algorithm using Spatial Frequency Domain Virtual Time Reversal
(2021-01-01)
Structural health monitoring techniques are widely used in industry applications to guarantee the integrity of several types of components. This article proposes a baseline-free damage imaging algorithm based on Spatial ...
A note on the state space representation of aeroelastic systems for time domain analysis
(2021-07-01)
The time domain state space model for describing an aeroelastic system has usually been obtained by using rational function approximations to write unsteady aerodynamics in the time domain. This strategy has been employed ...
Time-domain full-band method using orthogonal edge basis functions

Reaction-diffusion equations in a noncylindrical thin domain
(Springer, 2013-11-20)
In this paper we are concerned with nonlinear reaction-diffusion equations posed in a time-dependent family of domains {Omega(epsilon)(t)}(t is an element of R) subset of Rn+1 which collapses to a lower dimensional set as ...
Comparison between frequency domain and time domain riser analysis
(ASMENEW YORK, 2012)
In the optimization or parametric analyses of risers, several configurations must be analyzed. It is laborious to perform time domain solutions for the dynamic analysis, since they are time-consuming tasks. So, frequency ...
Sparse network equivalent based on time-domain fitting

Alternative proposal for Modal Representation of a Non-transposed Three-Phase Transmission Line with a Vertical Symmetry Plane
(Institute of Electrical and Electronics Engineers (IEEE), 2009-06-01)
The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is ...
