    Determination of the bentonite content in molding sands using AI-enhanced electrical impedance spectroscopy
    (2024) Ma, Xiaohu; Fischerauer, Alice; Haacke, Sebatian; Fischauer, Gerhard
    MUT-InfoMo data contains the measured raw impedance data recorded by Agilent E4980A LCR meter in a frequency range from 20 Hz to 1 MHz, along with water content and sample density. The measuring cell consists of two opposing electrodes embedded within the inner wall of a cylindrical chamber with a diameter of 5 cm. The electrodes, made from C45 steel, are insulated from the chamber walls using retaining rings fabricated from polyetheretherketone (PEEK). The measurements were performed at laboratory conditions. Columns from 1:201 are the real components of Impedance spectrum. Columns from 202:402 are the negative imaginary component of Impedance spectrum. Column 403 is the water content, column 404 is the density, column 405 is the target variable bentonite content. Finally, an excel data files was stored, with which the FCNNs were trained and tested.

    Raw impedance data for MUT MoNiCon and evaluation data for LSTM
    (University of Bayreuth, 2022-04-22) Ma, Xiaohu; Bifano, Luca; Fischerauer, Gerhard
    MUT-MoNiCon data contains the measured raw impedance data recorded by Agilent E4980A LCR meter in a frequency range from 20 Hz to 1 MHz (the data only from 20 Hz to 5 kHz is used). The measuring cell used is a parallel-plate capacitor with plate spacing 1 cm and plate diameter 13 cm. The measurements were performed at laboratory conditions. A tabstop is used as delimiter between the columns in all txt-files. In addition, the measurement logs are stored as pdf files, so that the filling quantities of the individual measurements can also be traced. Finally, two MATLAB data files are stored, with which the LSTMRNN was trained and tested.
