    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.

    ECT data, impedance data and temperature data presented in “Non-invasive temperature monitoring in fixed-bed reactors by electrical capacitance tomography"
    (University of Bayreuth, 2024) Weiss, Michael; Fischerauer, Alice; Jess, Andreas; Fischerauer, Gerhard
    The stored ZIP-file contains following three folders: ECT_data: contains the ECT data of the experiments shown in the paper. For each measurement the reference capacitances for the low and high calibration of the ECT measuring system, the recorded raw capacitances, the reconstructed normalized pixel permittivities as well as the corresponding time vector are provided for the different materials. In case of the catalyst FCDS_LQ3 also the calculated pixel temperatures are provided. The averaging over time as done in the paper has not been performed with the data provided here. Electrical_impedance_data: contains the recorded impedance data used for investigating the permittivity-temperature relationship of the different materials examined. Thermocouple_data: contains the temperature measurement data recorded with a thermocouple centered in the fixed-bed at the height of the measuring electrodes. This data was used for comparison with the pixel temperatures calculated from the ECT for the catalyst FCDS-LQ3

    In-situ monitoring of used-sand regeneration in foundries by impedance spectroscopy
    (University of Bayreuth, 2022-09-06) Bifano, Luca; Weider, Marco; Fischerauer, Alice; Wolf, Gotthard; Fischerauer, Gerhard
    MUT 1 to MUT 4 data contains the measured raw impedance data recorded by Agilent E4980A LCR meter in a frequency range from 20 Hz to 1 MHz. The measuring cells used are a cylindrical plate capacitor with plate spacing 4 cm and plate diameter 13 cm and a cylinder capacitor with an electrode spacing of 1 cm and an electrode height of 10 cm (name: laboratory data). MTP 0 to 5 data contains the measured raw impedance data of used-sand regenerated in a used-sand regenerator recorded by Agilent E4980A LCR meter in a frequency range from 20 Hz to 1 MHz (name: field data). 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, a matlab code listing is presented that describes the matlab programs used to evaluate the presented data (name: code listing). A description of the data can be found in the article "In-situ monitoring of used-sand regeneration in foundries by impedance spectroscopy".

    Original data of the publication: Capacitive gas-phase detection in liquid nitrogen
    (University of Bayreuth, 2017-02-14) Kandlbinder, Christoph; Fischerauer, Alice; Mösch, Mario; Helling, Tobias; Fischerauer, Gerhard; Siegl, Martin
    These data sets are raw simulated and measured data belonging to the article 'Capacitive gas-phase detection in liquid nitrogen' in the open-access peer-reviewed journal of Sensors and Sensor Systems (JSSS). The simulated data consists of the electrical field strength in every three-dimensional element for different fill levels of the receptacle and for a bubble stream inside the receptacle. Also, the points of the boiling curve are given. The measured data represents the ratio of the measured capacitance to a known capacitor for electrodes 1-3 and 2-5 for different measurements. It also includes the fill level values over time taken from the video as well as an important part of the respective video.

    Raw impedance data for MUT 1 to 6 and evaluation data for SVMs
    (University of Bayreuth, 2022-01-11) Bifano, Luca; Fischerauer, Alice; Fischerauer, Gerhard
    MUT 1 to MUT 6 data contains the measured raw impedance data recorded by Agilent E4980A LCR meter in a frequency range from 20 Hz to 1 MHz. The measuring cell used is a cylindrical plate capacitor with plate spacing 4 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. In addition, the values extracted from the raw data that were used to determine the bar charts are stored in an Excel file. Finally, two MATLAB data files are stored, with which the SVMs was trained and tested.
