Harmonics filtering and detection of disturbances using wavelets
(1999-12-01)
Traditional mathematical tools, like Fourier Analysis, have proven to be efficient when analyzing steady-state distortions; however, the growing utilization of electronically controlled loads and the generation of a new ...

Waveform selection for electrical impedance tomography
(Institute of Electrical and Electronics Engineers, 2013-04)
Electrical Impedance Tomography (EIT) is a non– invasive method that can be used to estimate the electrical conductivity of the head tissues. It is based on the measurement of electric potential on the scalp generated by ...
Synthesis of Sinusoidal Waveform References Synchronized With Periodic Signals
(Institute of Electrical and Electronics Engineers, 2008-03)
This paper proposes a novel method to generate a sinusoidal waveform synchronized with any measurable periodic signal whose frequency is within a given neighborhood. The synthesized sinusoidal signal could be used as a ...
Preliminary evaluation of a non-invasive device for monitoring intracranial pressure waveforms in dogs
(2022-01-01)
Objectives: The objective of this study was to compare waveforms obtained with a new device for the non-invasive monitoring of intracranial pressure (ICP) in dogs with and without neurological disease. Materials and Methods: ...
Static converter: didactic support software
(1994-01-01)
Teaching a course of special electric loads in a continuing education program to power engineers is a difficult task because they are not familiarized with switching topology circuits. Normally, in a typical program, many ...
Analysis of the Dielectric Behavior of Distribution Insulators Under Non-Standard Lightning Impulses Voltages
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
Overhead distribution lines are often exposed to lightning overvoltages, whose waveforms vary widely and can differ substantially from the standard impulse voltage waveform (1,2 - 50). Different models have been proposed ...
