As part of the scientific support programme after the closing of the Clay Conference, we offer you the opportunity to join Hands-on Monitoring at BGR: From in-situ investigation to numerical simulation on Thursday afternoon (28th of November).   Against the background of the requirements for the in-situ investigations and the determination of the specific parameters for a safety assessment for the disposal of radioactive waste, selected methods and instruments for the characterization of host rocks and barrier rocks will exemplarily be presented and the following aspects are highlighted: Which material parameters are used in modelling? What level of detail is necessary? And furthermore – which process variables have to be investigated with regard to the model set-up: What about simplifications regarding heterogeneities like EDZ or fault zones? What about the impact of geotechnical boundary conditions?   Find more information here: https://lnkd.in/eHY5g3Eg   Photo: View into the open niche of the CD-A experiment in the Mont Terri rock laboratory: The characterization of the host rock and the measurement of process variables such as deformation, water content and pore pressure provide important information for the development of numerical models.

Now, this is a talk that you shouldn't miss, the very first paper to highlight the benefits of the overlooked Compressibility/Shear Compliance properties. I bet it will be the talk of the town..

On the third and final day of the 2nd Congress of the PPGEM EP USP, Claus Naves Eikmeier presented his research. Title: Dynamic Time Warping Intermediate Data Approach For Fwi Cycle Skipping Mitigation Abstract: Full-waveform inversion is a seismic method for acquiring detailed subsurface images by using the entire content of the seismograms. This work presents an acoustic inversion for compressional wave (P wave) recovery. Despite the potential of the method, it encounters notable obstacles. A primary issue is the problem’s non-linearity, leading to a non-convex objective function and the possible occurrence of cycle skipping events. Cycle skipping may occur if the initial data is more than half a wave cycle away from the observed data. It means the initial model cannot be too different from the target one. This study introduces an alternative approach to address this challenge, called Dynamic Time Warping Multiscale Intermediate Signals Approach (DTW-MISA). The strategy consists of employing an intermediate data approach based on the dynamic time warping method. The results indicate an effective reduction of cycle skipping.

Master's Thesis: Seismic Resistance Evaluation of Steel Structures; I need a creative idea

It was really a pleasure to attend the ECSMGE24 in Lisbon. I’ve assisted to many interesting lectures and presentations. I suggest going through the proceedings (open access) and have a look to the papers of you area of interest. Starting with the papers that were presented in the plenary sessions. Lessons learned from the collapse of the historical archive in Cologne, and geotechnical aspects of the 2023 Earthquake in Turkey, are two impressive examples. https://lnkd.in/dHfutape

In two weeks after the early publication, the paper by me and Warner Marzocchi is the most read of Seismological Research Letters. It is our opinion about the issue of updating the seismic hazard model adopted by building code https://lnkd.in/ditisjVn

This is the combined Resonant Column-Torsional Simple Shear Device (RC-TOSS) with the fixed-free configuration. We use this unique design in the geotechnical laboratory at Széchenyi István University to study the dynamic behavior of soil. The drive head applies torque to the top of the hollow cylindrical specimen, where shear stresses and strains are measured. This allows for measurements of the shear modulus (soil stiffness) and damping ratio (energy dissipation) over a wide range of strains (0.0001-1)%. To learn more about the device and the theory behind it, and to stay updated on recent advances in the study of the dynamic behavior of sand, you can check out our literature review article in Geotechnics-MDPI. https://lnkd.in/dkAWzKaD
