Virtual instrumentation applied to the implementation of IEEE STD 1459-2000 power definitions
This paper discusses the utilization of Virtual Instrumentation to the implementation and evaluation of different power definitions, so that classical formulations and new definitions can be compared without the necessity ...
The oscillatory bioelectrical signal from plants explained by a simulated electrical model and tested using Lempel-Ziv complexity
(ELSEVIER SCI LTD, 2011)
This paper demonstrates the oscillatory characteristics of electrical signals acquired from two ornamental plant types (Epipremnum pinnatum and Philodendron scandens - Family Araceae), using a noninvasive acquisition system. ...
The use of pulsed electric acoustic technique for measuring the polarization reversal in ferroelectric ceramic samples
The pulsed electric acoustic technique, PEA, has been usually applied to probe space charge profiles in polymers. Preliminary PEA results using a ferroelectric ceramic are presented. If the reverse applied electric field ...
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 ...
Simplified procedure to estimate the resistance parameters of transmission lines
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 ...
