ID: 107 / Oral Session 3-1: 1 Abstract submission for on-site presentation Topics: Inverse problem, Application Keywords: magnetic dipole fit, Magnetic Marker Monitoring Online magnetic dipole localization with improved stability Physikalisch-Technische Bundesanstalt, Germany We stabilized the general Magnetic Marker Monitoring approach to obtain a more robust, reliable online reconstruction of a single magnetic dipole source form acquired multichannel magnetic field measurements with millisecond temporal resolution.

ID: 151 / Oral Session 3-1: 3 Abstract submission for on-site presentation Topics: Inverse problem, Application, Theoretical aspects and fundamentals Keywords: Maxwell's Equations, Parabolic Transmission Problem, Lorentzian Nanoparticle, Plasmonic and Dielectric Resonances. Heat Generation Using Lorentzian Nanoparticles. The Full Maxwell System 1Radon Institute (RICAM), Austrian Academy of Sciences, Austria; 2Johannes Keplar Universität Linz, Austria We analyse and quantify the amount of heat generated by a nanoparticle, injected in a background medium, while excited by incident electromagnetic waves. These nanoparticles are dispersive with electric permittivity following the Lorentz model. The purpose is to determine the quantity of heat generated extremely close to the nanoparticle (at a distance proportional to the radius of the nanoparticle). This study extends our previous results, derived in the 2D TM and TE regimes, to the full Maxwell system. We show that by exciting the medium with incident frequencies close to the Plasmonic or Dielectric resonant frequencies, we can generate any desired amount of heat close to the injected nanoparticle while the amount of heat decreases away from it. These results offer a wide range of potential applications in the areas of photo-thermal therapy, drug delivery, and material science, to cite a few. 9:30am - 9:50am
ID: 136 / Oral Session 3-1: 4 Abstract submission for on-site presentation Topics: Inverse problem, Application, Algorithms Keywords: beamformer, MEG, MNE-CPP, real-time, source reconstruction Real-Time Beamformer Application for MEG Source Reconstruction in MNE-CPP 1Technische Universität Ilmenau, Germany; 2UMIT TIROL, Austria A beamformer application for real-time source reconstruction was implemented for the open-source framework MNE-CPP. The performance of the new beamformer application was investigated regarding computation speed for simulated magnetoencephalography (MEG) data. Preliminary results show that a single source is reconstructed at the expected location and within a time sufficient for real-time applications. 9:50am - 10:10am
ID: 145 / Oral Session 3-1: 5 Abstract submission for online presentation Topics: Inverse problem, Application Keywords: EEG, Epilepsy, Functional Connectivity, Phase Lag Index, Seizures Graph-based Functional Connectivity Analysis and Inverse Problem of EEG in Subjects with Epilepsy 1Department of Civil, Computer Science and Aeronautical Technologies Engineering, Roma Tre University, Italy; 2DICEAM Department, University “Mediterranea” of Reggio Calabria, Italy Studying changes in cortical sources and functional connectivity in subjects with epilepsy can offer valuable insights into the alterations caused by the disease. To investigate these changes, a customized pipeline is used to compute functional connectivity based on EEG signals measured on the scalp. The inverse problem solution, which is a computational approach used to estimate the related cortical source areas, is proposed to identify detectable pre-ictal functional activities at source levels. This approach allows to compare the alterations occurring in both the electrodes and cortical sources during the pre-ictal state of the brain in subjects with epilepsy. Graph measures based on Phase Lag Index (PLI) are employed to quantify phase differences between signals originating from distinct brain areas, while considering their corresponding connection strengths, integration and segregation. This analysis assesses the level of connectivity and information exchange among different brain regions, investigating mechanisms and potential markers associated with epileptic activity. Preliminary results of the connectivity analysis will be presented, along with the necessity of determining cortical sources through the estimation of the inverse problem for accurate identification of the anomaly. |

ID: 132 / Oral Session 3-2: 1 Abstract submission for on-site presentation Topics: Inverse problem Keywords: Hysteresis, Inverse problems, Material data, Neural networks, PINNs. Material data identification by application of physics informed neural networks on an induction heating test rig 1Materials Center Leoben Forschung GmbH (MCL), Austria; 2Materials Center Leoben Forschung GmbH (MCL), Austria; 3Technical University of Graz, Institute for the fundamentals and theory of electrical engineering, Austria; 4Materials Center Leoben Forschung GmbH (MCL), Austria Physics informed neural networks (PINNs) are at the center of attention in diversity of applications, especially for material data identification and engineering. In this work, we investigate the feasibility of material data identification using PINNs. We aim to identify thermo-physical properties, such as specific heat, thermal conductivity, as well as B-H characteristics relevant to hysteresis of materials. We show that the thermo-physical properties are identified quite accurately using few temperature sensor data of an air cooled cylindrical sample. Moreover, the B-H characteristics of the pure iron is approximated applying PINNs by incorporating the physics of the equivalent magnetic circuit of the yoke-based measurement setup and using a secondary voltage and primary excitation signal of the transformer as an input. 10:50am - 11:10am

The procedure has been enhanced to account for the electrical conductivity of the heat exchanger that stimulates the flow.

ID: 115 / Oral Session 3-3: 2 Abstract submission for online presentation Topics: Inverse problem Keywords: Deep learning, source-identification problem, magnetic field A magnetostatic source-identification problem solved by means of deep learning methods 1DESTEC Department, University of Pisa, Italy; 2Dept. of Electrical, Computer and Biomedical Engineering,University of Pavia, Italy In this work, a Deep Learning approach based on a Conditional Variational Autoencoder (CVAE) has been adopted for the solution of an inverse problems of magnetic field reconstruction knowing the field on a subdomain. Subsequently, starting from the CVAE outputs, the geometry of the field source can be identified. Two different techniques are used: a deep artificial neural network, fully connected, and a convolutional neural network. The proposed methods are applied to the TEAM 35 benchmark magnetostatic problem and a comparison between them is done. |
