Using state-space techniques to represent frequency dependent single-phase lines directly in time domain
(2008-12-01)
This paper proposes to use a state-space technique to represent a frequency dependent line for simulating electromagnetic transients directly in time domain. The distributed nature of the line is represented by a multiple ...
Corona effect in frequency dependent transmission line models
(2008-12-01)
The inclusion of the corona effect in a frequency dependent transmission line model is proposed in this paper. The transmission line is represented through a cascade of π circuits and the frequency dependence of the ...

Transmission lines model with different basic structures applied to transient electromagnetic simulations
(2016-01-01)
Models based on lumped elements are simple ones to represent systems composed by distributed parameters when models with lumped elements use a lot of these elements. However, such mentioned models usually present numerical ...
Global optimization approach for the H2-norm model reduction problem
(1999-12-01)
A branch and bound algorithm is proposed to solve the H2-norm model reduction problem for continuous-time linear systems, with conditions assuring convergence to the global optimum in finite time. The lower and upper bounds ...
Numerical assessment of mass conservation on a MAC-type method for viscoelastic free surface flows
(2012-12-01)
A numerical study of mass conservation of MAC-type methods is presented, for viscoelastic free-surface flows. We use an implicit formulation which allows for greater time steps, and therefore time marching schemes for ...
Using otsu's threshold selection method for eliminating terms in vector space model computation
(2013-12-01)
Visualization techniques have proved to be valuable tools to support textual data exploration. Dimensionality reduction techniques have been widely used to produce visual representation of document collections. Focusing ...

Laboratory Tests with Model Based on pi Circuits Considering the Introduction of Branches Composing by RL Parallel Elements
(Ieee, 2018-01-01)
For simple transmission line models, it can be applied pi circuit cascades. This type of circuits was applied for composing a physical model that has been applied for simulating of propagation of simple electromagnetic ...
