The method is an improved version of the Combined Geoelectric Inversion (CGI) robustified by involving Cauchy-Steiner weights in an Iteratively Reweighted Least Squares technique. The new procedure is compared to the Fourier series expansion-based 1.5D and the CGI methods as well as to the broadly applied RES2DINV inversion procedure. The field measurements are performed during stone exploration in an active quarry on the south-western slopes of the Mátra mountains, in northern Hungary. It is shown that the CGWI method gives stable and robust parameter estimation with acceptable accuracy. The comparison with other inversion methods is based on data distances, estimation errors and correlation parameters calculated on the base of the parameter correlation matrix.}, year = {2024}, eissn = {1789-3348}, orcid-numbers = {Nádasi, Endre/0000-0001-5325-6657} } @article{MTMT:34765634, title = {A hazai fosszilisszénhidrogén-vagyonban rejlő lehetőségek}, url = {https://m2.mtmt.hu/api/publication/34765634}, author = {Velledits, Felicitász and Kiss, Károly and Baracza, Mátyás Krisztián}, doi = {10.1556/112.2023.00165}, journal-iso = {SCI SEC}, journal = {SCIENTIA ET SECURITAS}, volume = {5}, unique-id = {34765634}, year = {2024}, eissn = {2732-2688}, pages = {1-11} } @article{MTMT:34528126, title = {Archeogeophysical application of non-traditional geoelectric arrays. a case study in a north-east Hungary site}, url = {https://m2.mtmt.hu/api/publication/34528126}, author = {Kárpi, Marcell and Baracza, Mátyás Krisztián and Szalai, Sándor}, doi = {10.47833/2024.1.ENG.001}, journal-iso = {GRADUS}, journal = {GRADUS}, volume = {11}, unique-id = {34528126}, abstract = {With the continuous development of multielectrode geoelectrical tomography (ERT) as a geophysical technique, we became able to detect small size targets. In this paper, we present ERT interpretation results obtained at an archaeological site in Szendrő village in northeastern Hungary, where a 17th century fortress once stood. Several historical notes and a collapsed entrance recall the existence of tunnels under the fortress and a water well of uncertain depth. To detect these structures, geoelectrical multielectrode measurements were carried out using conventional and quasi-null arrays. The quasi-null array applies the arrangement of the current (A and B) and potential electrodes (M and N) in a special way, i.e., the electrodes A, M, B, N follow each other in line in special distances from each other. The horizontal sensitivity of the resistivity profiling method using these types of arrays has been proven to be better than that of the Wenner or other conventional arrays. The comparative study aims not just to investigate the archeological features, but to test the sensitivity of the non-traditional quasi-null arrays to these two-dimensional inhomogeneities. As a result, the optimal array can be chosen, and the identification and delineation of shallow structures can be made more reliably. In this paper, we present the very first archeogeophysical field measurements carried out by the gamma quasi null array (γqnull).}, year = {2024}, eissn = {2064-8014} } @article{MTMT:34399693, title = {Fracture system characterization by Pressure Probe}, url = {https://m2.mtmt.hu/api/publication/34399693}, author = {Szalai, Sándor and Szűcs, Péter and Lemperger, István and Zubair, M and Metwaly, M and Gribovszki, Katalin Eszter and Baracza, Mátyás Krisztián}, doi = {10.3311/PPci.19916}, journal-iso = {PERIOD POLYTECH CIV ENG}, journal = {PERIODICA POLYTECHNICA-CIVIL ENGINEERING}, volume = {68}, unique-id = {34399693}, issn = {0553-6626}, abstract = {Pressure Probe (PreP) is in effect a simplified penetrometer: it measures the mechanical resistivity of the soil at shallow depths dropping the probe always from the same height. The resolution of this technique is very good. It is able to detect e.g., fractures due to their decreased mechanical resistance if they are covered, but in a shallow depth with a reasonable sampling distance. An example will be demonstrated where fracture system of a slowly-moving landslide was characterized enabling also its delineation. In spite of that its maximal penetration is only about 0.5 m it may also give information from remarkable depths in case if fractures reach close to the surface indicating the borders of geological structures in larger depth. An example from India will be shown to present such results. All results have been verified by geoelectric measurements.
