Simplified procedure to estimate the resistance parameters of transmission lines
(2013-09-01)
An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the ...
Sampling Rate Impact on Estimation of Untransposed Transmission Line Parameters Based on Fault Records
(Springer, 2018-06-01)
This paper highlights the sampling rate impact over an estimation method based on modal analysis techniques applied on untransposed three-phase transmission line. The analysed method represents a transmission system in the ...

Application of modal-phase domain relations to estimate transmission line parameters
(Inst Engineering Technology-iet, 2019-07-01)
The accuracy of transmission line parameters (TLPs) allows the proper response to faults or load variations and the monitoring of common fault indicators, such as the conductor's temperature and sag. TLP estimation ...
Estimation of transmission line parameters using multiple methods
(2015-12-03)
An estimation procedure for transmission line parameters is developed that combines a new method of determining line parameters with others available in the technical literature. Each estimation method has certain advantages ...
Chemical abundance analysis of the Be star HD 171054
(ELSEVIER SCIENCE BV, 2011)
In this work the results of a spectroscopic study of the southern field narrow-line Be star HD 171054 are presented. High dispersion and signal-to-noise ratio spectra allowed the estimation of the fundamental photospheric ...
Offline Detection, Identification, and Correction of Branch Parameter Errors Based on Several Measurement Snapshots
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
This paper proposes a three-stage offline approach to detect, identify, and correct series and shunt branch parameter errors. In Stage 1 the branches suspected of having parameter errors are identified through an Identification ...
Line based camera calibration in machine vision dynamic applications
(1999-12-01)
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object ...
Bayesian inference in single-line spectroscopic binaries with a visual orbit
(IOP, 2022)
We present a Bayesian inference methodology for the estimation of orbital parameters on single-line spectroscopic binaries with astrometric data, based on the No-U-Turn sampler Markov chain Monte Carlo algorithm. Our ...
High and intermediate-resolution spectroscopy of Be stars : an atlas of Hg, He I 4471 and Mg II 4481 lines
(EDP Sciences, 2001-11)
We present an atlas of Hγ, He i λ 4471 and Mg ii λ 4481 line profiles obtained in a 10 year observation period of 116 Be stars, which enabled many of them to be observed at quite different emission epochs. From the best ...
