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 ...
Instantaneous Frequency Image
(2021-05-01)
The instantaneous frequency (IF) image is proposed in this work. It is obtained by the differentiation of the instantaneous phase (IP) image, which in turn is calculated by replacing the amplitude information with the IP ...

Vector control of a modular multilevel matrix converter operating over the full output-frequency range
(Institute of Electrical and Electronics Engineers Inc., 2019)
© 1982-2012 IEEE. The modular multilevel matrix converter (M 3 C) is an ac-to-ac converter topology suitable for the control of high-power variable-speed drives. The control of this converter is complex, particularly when ...
Phase-Locked loops lock-in range in Frequency Modulated-Atomic Force Microscope nonlinear control system
(Elsevier B.V., 2012-07-01)
Since the mid 1980s the Atomic Force Microscope is one the most powerful tools to perform surface investigation, and since 1995 Non-Contact AFM achieved true atomic resolution. The Frequency-Modulated Atomic Force Microscope ...
