Possibilities in the application of machine learning on bioimpedance time-series

presenting and analyzing bioimpedance data. The advantage in machine learning methods is the possibility of learning generalizable predictive patterns in combining variables in a non-linear fashion, possibly increasing the predictive performance compared to simpler models. In addition, machine learning can be used to perform automatic feature extraction, useful when there is a lot of variables (e.g. different immittance parameters over many frequencies) and the important ones are not known. In some cases, such as clinical monitoring, the prediction performance is

Biomass measurement of living Lumbriculus variegatus with impedance spectroscopy

Introduction Electrical properties of biological tissues have been studied for over a century [ 1 ]. A large variety of different biological tissues have been investigated with the help of impedance spectroscopy, a detailed review on various human and animal tissue and blood samples can be found, e.g., in the review by Gabriel et al. [ 2 ]. Fricke and Curtis [ 3 ] investigated the impedance of yeast cell suspensions in the early 1930´s. They concluded that the impedance at the surface of the yeast cell is derived from a poorly conducting membrane which acts

Hydraulic Characterization of a Self-Weight Compacted Coal

1 Introduction The stocks of coal are crucial areas of coal-fired power plants, in terms of safety, optimization of energy storage and environmental implications (e.g., [ 1 ], [ 2 ]). Although they are now usually protected from rain and wind by storage structures or more simply by coating with tarpaulins, in many old plants in the world these stocks are still exposed to natural climatic conditions such as rain. This climatic condition could allow the air pollution with fine coal particles, as close to mining areas (e.g., [ 3 ]), and leaching processes due to
