Preliminary results concerning the VSS X- chart with unknow in-control parameters
(2010-12-01)
The VSS X- chart is known to perform better than the traditional X- control chart in detecting small to moderate mean shifts in the process. Many researchers have used this chart in order to detect a process mean shift ...
A procedure to estimate parameters of a line segment taking into account its representation through π circuits: Theoretical development
(2006-12-01)
The objective of this paper is to show an alternative methodology to estimate per unit length parameters of a line segment of a transmission line. With this methodology the line segment parameters can be obtained starting ...
A disease evolution model with uncertain parameters
(2001-12-01)
In this study we consider the SIS epidemiological model (susceptible-infected-susceptible) in which the transmission and recuperation rates are considered fuzzy sets. The concepts of possibility measures and fuzzy expectancy ...
Transmission Line Parameter Error Detection, Identification and Correction with Geometrical View: Topological Errors
(Ieee, 2015-01-01)
correct series and shunt branch parameter errors of a transmission line using a geometrical view. Firstly it is tested if any of the measurement equations have a gross error using the J(x) index, but with the measurement ...

(2015-08-31)
In this paper it is proposed an approach to detect, identify and correct series and shunt branch parameter errors of a transmission line using a geometrical view. Firstly it is tested if any of the measurement equations ...
Comparing Lumped and Distributed Parameters Models in Transmission Lines during Transient Conditions
(Ieee, 2014-01-01)
The solutions of differential equations of transmission line are generally difficult to obtain due to the convolution integral present. Considering this, there are models proposed for the study of electromagnetic transients ...

A neural network approach for robust nonlinear parameter estimation in presence of unknown-but-bounded errors
(Elsevier B.V., 2000-01-01)
Systems based on artificial neural networks have high computational rates due to the use of a massive number of simple processing elements and the high degree of connectivity between these elements. This paper presents a ...
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 ...
Estimation of parameters for faulted transposed transmission lines
(Ieee, 2018-01-01)
This paper presents a method to estimate transmission line parameters for transposed lines from faulted current and voltage measurements at the line's terminals, in the time domain. The measurements are transformed to the ...
