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 ...
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: ...
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 ...
Waveform inversion and focal mechanisms of two weak earthquakes in Cordillera Principal (Argentina) between 35° and 35.5° S
(Pergamon-Elsevier Science Ltd, 2016-11)
Only few (six) focal mechanism, in CMT Catalog, have been so far known for intraplate shallow events in the Andean chain close to Chile–Argentina state border at latitudes ∼35° S. We add two more mechanisms, depths and ...
Practical evaluation of different modulation techniques for current-controlled voltage source inverters
(INST ENGINEERING TECHNOLOGY-IET, 1996)
The quality of the current waveform generated by a current-controlled, voltage source inverter, depends basically on three factors: (a) the switching frequency of the PWM modulator; (b) the type of current waveform being ...
