Three-phase harmonic distortion state estimation algorithm based on evolutionary strategies
(ELSEVIER SCIENCE SA, 2010)
This paper presents a new methodology to estimate unbalanced harmonic distortions in a power system, based on measurements of a limited number of given sites. The algorithm utilizes evolutionary strategies (ES), a development ...
Contribution of distributed generators to the harmonic distortion in low voltage power network
(2010-12-01)
In the last 20 years immense efforts have been made to utilize renewable energy sources for electric power generation. This paper investigates some aspects of integration of the distributed generators into the low voltage ...

Numerical analysis of the straightening process of thin plate structures by elastic FEM based on the inherent strain method
(2012-12)
Welding distortion is practically an expected feature in shipbuilding, with a few exceptions; when thick plates are used, for example. Nowadays, the trend is to use thinner plates in order to reduce weight, aiming to reduce ...
Velocity fields using NURBS with distortion control for structural shape optimization

Transient evoked and distortion product otoacoustic emissions in a group of neonates
(Fundação Otorrinolaringologia, 2015-09-01)
Introduction The most commonly used method in neonatal hearing screening programs is transient evoked otoacoustic emissions in the first stage of the process. There are few studies comparing transient evoked otoacoustic ...
The finite-sample size of the BDS test for GARCH standardized residuals
(2014-05-05)
This paper uses a multivariate response surface methodology to analyze the size distortion of the BDS test when applied to standardized residuals of rst-order GARCH processes. The results show that the asymptotic standard ...

Design and simulation of techniques for mitigation of harmonic distortion in a three-phase rectifier
(Cartagena de Indias, 2020)
Rectifiers are electrical devices that receive an alternating signal and deliver a direct current signal at their output, this process by which they transform one type of energy to another is known as rectification. This ...
