The interest in fractional-order (FO) control can be traced back to the late nineteenth century.
The growing tendency towards using fractional-order proportional-integral-derivative …

The interest towards using Fractional-order (FO) PID controllers in the industry is mainly
fueled by the fact that these controllers have two additional “tuning knobs” that can be used …

A general framework for fractional signal processing is described and used to derive several
interesting formulations. This scheme is based on the Liouville approach that gave rise to …

The impulse signal is an instant change signal in very short time. It is widely used in signal
processing, electronic technique, communication and system identification. This paper …

Electrosurgery uses electric current to heat, coagulate and ligate tissue. The current flow
induces a voltage due to the bio-impedance of the tissue. The flow of the current should be …

Throughout various engineering applications, measurement science faces the problem that
parameters of interest are not directly measurable with a specifically designed instrument …

Fractional calculus is a mathematical tool for augmenting conventional integrals and
derivatives. When introduced to control theory, it poses new opportunities and challenges for …

Electrical impedance spectroscopy (EIS) is a tool for characterizing the electrical behavior of
matter. Nevertheless, most of the work is focused on purely experimental results, leading …

Electrochemical impedance spectroscopy (EIS) allows measuring the properties of the
system as a function of the frequency as well as distinguishing between processes that …

The article presents a methodology to discriminate glucose levels using electrical
impedance spectroscopy technology. The method is based on an adequate estimation and …
