Assessment and Reduction of Uncertainties in Operational Modal Analysis (RUN-OMA) : Supplemental Data
The RUN-OMA project developed a novel methodology to objectively and transparently evaluate the quality of results from Operational Modal Analysis (OMA) — a technique used to determine the modal parameter of structures, such as natural frequencies, damping ratios and mode shapes. These properties are…
Fyoris : Full-polarimetric V2I MIMO channel sounding data sets @2.53GHz in urban environment, together with pertinent antenna…
Seven measurement runs, selected from a measurement campaign in Bonn, Germany, are provided. The environment is urban, the context is V2I from an elevated base station, the set-up is fully polarimetric MIMO with two 16 dual-pol element stacked circular arrays, configured as two circular rings of 8 elements…
Elowen : MIMO Channel Sounding and Characterization in an Urban Macro Cell
The measurement campaign was performed in Cologne (Germany) using a RUSK MIMO channel sounder operating at 2.53 GHz. The fixed transmitter has been mounted on a roof top of an approx. 30m high building whereas the mobile receiver has been set up in a car. The application of high resolution parameter…
Structural analysis of 2D frame structures using Physics Informed Neural Networks : Calculation files and result data
Within the present study, a framework for Physics Informed Neural Networks (PINN) is formulated for the analysis of frame structures in two dimensions. The individual structural elements are represented by Euler-Bernoulli beams with additional axial stiffness. The transverse and axial displacements are…
Anti-Muslim Narratives by the AfD and FPÖ on X (Twitter), 2024-2025
Right-wing populist parties increasingly leverage digital media to reshape European politics. This thesis investigates how the Alternative for Germany (AfD) and the Freedom Party of Austria (FPÖ) construct and deploy anti-Muslim narratives on X (formerly Twitter). Through a multimodal critical discourse…
Der Rücken – Anschauliche Wissenschaft für die eigenverantwortliche Gesundheitsgestaltung : Videosammlung
Unser Ziel war es, eine Animation zu erstellen, die die OEMG-Aktivität der Muskeln beim gehenden Menschen, die Faszikelarchitektur und die Verteilung von Muskelfasertypen zeigt und die Funktionsmorphologie der Rumpfmuskulatur verständlich vermittelt. Es soll ein effektiver Wissenstransfer von der Forschung…
A FIB-SEM Protocol for High-Resolution Imaging Combined with EDX Analysis of Cement-Based Materials with Minimized Damage
This is a recording of a talk held at the Microscopy Conference 2025 in Karlsruhe given on 4 September 2025. It shows how lift-out technique helps to avoid artefacts such as shadowing during the FIB nanotomography process and how post-processing is carried out for such a BSE+EDX data set. This dataset…
FIB-SEM nano tomography protocol for high-resolution imaging of cementitous specimens combined with EDX analysis
This data set contains two tutorial videos that demonstrate how focused ion beam nano tomography can be applied to cementitious samples (here a CEM I) in order to image them with as few artefacts as possible. To do this, a volume (approx. 20 x 20 x 20 µm³) is prepared from the bulk material (part 1)…
Animation to visualize the electron beam damage induced in calcium silicate hydrate phases
This dataset visualizes the electron beam damage induced by a scanning electron microscope (SEM) in calcium silicate hydrates (C-S-H). The specimen used is 28 days hydrated alite (water/solid = 0.5). It was scanned using a thermofischer scientific Helios G4 UX microscope at 350 V/25 pA with a stage bias…
Robust design optimization of tuned mass dampers in structural dynamics using efficient reduced order models : Calculation…
In the study, efficient methods for the optimal design of Tuned mass damper parameters for linear SDOF and MDOF systems by considering parameter uncertainty are presented. In a first step, a perturbation approach for the uncertainty propagation, where the system responses are linearized by a Taylor series…
