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 ...
Fault location in underground systems through optimum-path forest
(2011-12-21)
In this paper we propose an accurate method for fault location in underground distribution systems by means of an Optimum-Path Forest (OPF) classifier. We applied the Time Domains Reflectometry method for signal acquisition, ...
Proposal of a simplified process to correct the phase decoupling using modal analysis
(2012-12-11)
Modal analysis is widely approached in the classic theory of transmission line modeling. This technique is applied to model the three-phase representation of conventional electric systems taking into account their self and ...
Patellofemoral pain syndrome: Electromyography in a frequency domain analysis
(2011-12-29)
The Patellofemoral Pain Syndrome (PFPS), has a multifactorial etiology and affects approximately 7 to 15% of the population, mostly women, youth, adults and active persons. PFPS causes anterior or retropatelar pain that ...
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 ...
Detection of Malicious Domains Using Passive DNS with XGBoost
(2020-11-09)
The Domain Name System (DNS) has as its main function the mapping of domain names to IPs and vice versa. Because of its function combined with the exponential growth of the internet, it has become an essential component. ...

A Time-domain Harmonic Power-Flow Analysis in Electrical Energy Distribution Networks, Using Norton Models for Non-linear Loading
(Ieee, 2014-01-01)
The purpose of this paper is to present the application of a three-phase harmonic propagation analysis time-domain tool, using the Norton model to approach the modeling of non-linear loads, making the harmonics currents ...
leA New Methodology for Calculating Electromagnetic Transients in Transmission Lines
(Ieee, 2018-01-01)
This paper shows a simple and efficient methodology using recursive convolutions and Vector Fitting to simulate electromagnetic transients of a single-phase transmission line during a switching procedure directly in the ...
