Impedance of Aqueous Solutions of KCl at the Ultra-low Frequency Range: Use of Cole-Cole Impedance Element to Account for the Frequency Dispersion Peak at 20 mHz
(2016-02-01)
This paper reports on the analysis of dispersion in the imaginary part of impedance often observed at low frequencies in a variety of systems. The experimental data were obtained with an electrolytic cell containing KCl ...
Fully Adaptive Ridge Detection Based on STFT Phase Information
(Institute of Electrical and Electronics Engineers, 2020-04)
This letter deals with the problem of the estimation of the instantaneous frequencies of the modes of multicomponent signals from their linear time-frequency representations. In most approaches, such an estimation consists ...
Repetitive Control With Adaptive Sampling Frequency for Wind Power Generation Systems
(Institute of Electrical and Electronics Engineers, 2014-03)
This paper presents a novel repetitive control (RC) for wind power generation systems (WPGS), which achieves optimal performance in steady-state conditions due to a variable sampling/switching period technique (VSPT). The ...
Feature extraction using frequency spectrum and time domain analysis of vibration signals to monitoring advanced ceramic in grinding process
(Inst Engineering Technology-iet, 2019-01-01)
New alternatives for monitoring the ceramic grinding process have been studied. Monitoring vibration signals is one of the most successful methods because some characteristics that describe the behaviour and influence of ...
Dynamic analysis of a new piezoelectric flextensional actuator using the J1-J4 optical interferometric method
(2005-12-01)
Piezoelectric actuators are widely used in positioning systems which demand high resolution such as scanning microscopy, fast mirror scanners, vibration cancellation, cell manipulation, etc. In this work a piezoelectric ...
