Strain curves measured with different DFOS types and varying spatial resolution by an ODiSI 6108

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.datacite.resourceType[].value
A tsv file with associated metadata is stored for each of the individual combinations of displacement step (1-14 mm), gage pitch (0.65 mm, 1.30 mm, 2.60 mm, 5.20 mm) and DFOS type (ACR, ES, ORM, V9). This makes a total of 14 x 4 x 4 = 224 files. The files were processed using Python.

Based on the principle of coherent optical frequency domain reflectometery (c-OFDR), cracks in concrete structures can be precisely localized and their widths determined due to the high spatial resolution in the sub-millimeter range. However, with longer distributed fiber optic sensors (DFOS) lengths, as is common in structural health monitoring, the spatial resolution is reduced. Experimental studies were carried out to investigate the influence of the spatial resolution on the measurement quality in the area of large strain gradients. Four different DFOS, two robust and two filigree DFOS types, were subsequently installed on a 4 m long reinforced concrete beam. In a displacement controlled 4-point bending test, crack widths of up to 0.5 mm were measured with four different gage pitch (gp).

The goal of the IDA-KI research project is to develop methods for automated analysis and evaluation of monitoring data. The validation is carried out using real measurement data acquired on a 45 m long research bridge (openLAB). First, the reference condition of the bridge is measured with and without service loads over a period of one year. Subsequently, targeted load tests will be performed up to the severe damage state. At the same time, redundant sensors will be damaged or manipulated to create a real database with specific signal characteristics for metrological and structural anomalies. This will provide an important basis for the development of evaluation methods (also based on machine learning), so that measurement faults in monitoring data can be corrected in the future and differentiated from structural damage.

Ultrafast switching of trions in 2D materials by terahertz photons

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
External control of optical excitations is key for manipulating light–matter coupling and is highly desirable for photonic technologies. Excitons in monolayer semiconductors emerged as a unique nanoscale platform in this context, offering strong light–matter coupling, spin–valley locking and exceptional tunability. Crucially, they allow electrical switching of their optical response due to efficient interactions of excitonic emitters with free charge carriers, forming new quasiparticles known as trions and Fermi polarons. However, there are major limitations to how fast the light emission of these states can be tuned, restricting the majority of applications to an essentially static regime. Here we demonstrate switching of excitonic light emitters in monolayer semiconductors on ultrafast picosecond time scales by applying short pulses in the terahertz spectral range following optical injection. The process is based on a rapid conversion of trions to excitons by absorption of terahertz photons inducing photodetachment. Monitoring time-resolved emission dynamics in optical-pump/terahertz-push experiments, we achieve the required resonance conditions as well as demonstrate tunability of the process with delay time and terahertz pulse power. Our results introduce a versatile experimental tool for fundamental research of light-emitting excitations of composite Bose–Fermi mixtures and open up pathways towards technological developments of new types of nanophotonic device based on atomically thin materials.

Weighted Shapley values and allocation of portfolio risk: One approach to solve the low-risk puzzle?

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.datacite.resourceType[].value
Simulation study, We analyze three-asset scenario with low-risk puzzle on the set of assets. We simulate 100,000 times. For different level structures, we calculate the weighted Shapley value (Kalai / Samet), the Haeringer weighted value and the proportional Shapley value. We identify cases with rank order corrections with respect to asset variance.

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
The data set contains data for the article “Weighted Shapley values and allocation of portfolio risk: One approach to solve the low-risk puzzle?”. This includes a description of the simulation settings, the Excel macros for calculating the results in the case of equal shares and random asset shares, and the 100,000 simulation results for both cases in Excel.

Abstract of the paper: In this article, we extend the application of cooperative game theory to solve the so-called low-risk puzzle. Specifically, we apply concepts that consider asset weights in the allocation of portfolio risk. These weights can take into account various asset characteristics (e.g., image, popularity of an asset, corporate social responsibility, innovative strength) that have not been previously considered in portfolio risk allocation using cooperative game theory. We demonstrate the application through a simulation study. Our results show that considering assets weights could deliver added value when solving the low-risk puzzle.

Correlation Velocimetry inside a model of the human airways

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.datacite.description.TechnicalInfo[].value
The time lag between both signals can be derived using cross-correlation between both channels. In combination with the physical distance between the regions observed by each photodiode, the average velocity can be calculated using: v = Δs/Δt with Δs distance between detectors (272 micrometer) and Δt time lag from cross-correlation. A detailed evaluation is presented in the corresponding publication: Kluwe et al. 2025 "Deterministic periodic structures in a model of the human airways" DOI: 10.1007/s00348-025-03971-9

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.datacite.resourceType[].value

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
The dataset corresponds to the publication "Deterministic periodic structures in a model of the human airways" by Kluwe et al. 2025. It contains raw data obtained from an optical setup used for point-wise velocity measurements using Correlation Velocimetry in a model of human airways. The recorded data consists of stereo audio files sampling the photo-electric response of two photodiodes to the passage of tracer particles. The time lag between both signals corresponds to the mean time of flight of ensembles of particles between both detectors. Using the known distance between the detectors (272 micrometers), the mean velocity of the tracer particles can be calculated. This dataset includes the raw data evaluated and discussed in the publication.

Monitoring Data of the openLAB Research Bridge – Load Test on PE 2.1

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Between May 5 and 7, 2025, extensive experiments were carried out on the openLAB research bridge. The test program was structured as follows: 
 
• Day 1: Static and dynamic measurements in the reference state 
• Day 2: Loading of the bridge using hydraulic jacks up to the ultimate limit state (yielding of prestressing steel) 
• Day 3: Local damage of prestressing tendons (cutting wires at several locations) 
 
The present dataset contains force and displacement measurements from the load test conducted on Day 2. The load was applied locally to precast element (PE) 2.1 (Field 2, PE axis 1) using two hydraulic jacks and increased up to 400 kN. Displacements were measured at five different positions along PE axis 1.

Raw data of the paper "Brillouin spectroscopic investigation of corneal hydration and the impact of cross-linking therapy on water retention"

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.opara.project.description[].value
Recently, Brillouin spectroscopy has been proposed as a promising non-invasive tool to evaluate corneal biomechanics, e.g. during corneal cross-linking (CXL) treatment. However, the impact of corneal hydration on the Brillouin shift hampers straightforward interpretation of the measurements, especially when judging on the success of the CXL procedure. Therefore, in this work, we first quantify the effect of corneal (de)hydration on the Brillouin shift revealing that reliable measurements are only possible under constant hydration conditions, which was subsequently achieved by immersing porcine eyes in solution and waiting until an equilibrium state was reached. Investigations showed that Brillouin spectroscopy evaluates the CXL effect mainly indirectly via reduced water uptake, while polarization-sensitive optical coherence tomography evaluates the CXL effect directly via changes in collagen fiber alignment and is therefore insensitive to corneal hydration. Raman spectroscopy is not indicating any alterations in the molecular structure revealing that new cross-links are not created due to the CXL procedure. Compared to large water retention in balanced salt solution, the missing water uptake in dextran-based (16%) solution hampers the evaluation of the CXL effect by Brillouin spectroscopy.

There are four .xlsx files available: "cracked.xlsx", "prestressed.xlsx", "unloaded.xlsx" and "Evaluation.xlsx".

The files "cracked.xlsx", "prestressed.xlsx" and "unloaded.xlsx" include the following datasheets:
- "Measurement_orginal_tsv" - the original .tsv-dataset of ODiSi6100 imported into excel
- "Measurement_reorientated" - the inverted dataset used for manual strain reading anomalie detection
- "Measurement_marked" - the measurement with marked strain reading anomalies (marked as "SRA")

The file "Evaluation.xlsx" includes datasheets for each load step for "SRA" and "NaN" (dropouts), which include information about each registrated SRA and dropout. Additionally, "Evaluation.xlsx" includes a datasheet called "Categorie" in order to clarify the assignment of the SRA to a category regarding their neighbouring datatype (accurate strain value, SRA, dopout).

Three different strain measurements with distributed fibre optic sensors using the ODiSI 6100 in different load conditions have been analyzed regarding the occurence of strain reading anomalis. Therefore, strain reading anomalies have been marked manually. 

The load states include a cracked state ( prestressed concrete specimen in 4-point-bending with increasing load), a prestressed state (concrete specimen after prestressing, small cracking) and an unloaded state (prestressed concrete specimen). The used EpsilonSensors (3 mm, ripped) of NerveSensors have been embedded in the concrete specimens. All measurements have been carried out using a gage pitch of 1.3 mm and frequencies between 1 and 6 Hz. The key has been created before concreting of the specimens.

The datasets can be used f.e. for the evaluation of pre-processing algorithms or the creation of benchmark datasets.

The datasets have been choosen due to their bad measurement quality and are no measure for the overall quality of distributed fibre optic strain sensing measurements. The quality issues might be due to dirty connections, scratched connections or sharp strain gradients.

Correlation Clustering of Organoid Images: Data

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.opara.project.description[].value
In biological and medical research, scientists now routinely acquire microscopy images of hundreds of morphologically heterogeneous organoids and are then faced with the task of finding patterns in the image collection, i.e., subsets of organoids that appear similar and potentially represent the same morphological class. We implement models and algorithms for correlating organoid images, i.e., for quantifying the similarity in appearance and geometry of the organoids they depict, and for clustering organoid images by consolidating conflicting correlations. For correlating organoid images, we implement and compare two alternatives, a partial quadratic assignment problem and a twin network. For clustering organoid images, we employ the correlation clustering problem. Empirically, we learn the parameters of these models, infer a clustering of organoid images, and quantify the accuracy of the inferred clusters, with respect to a training set and a test set we contribute of state-of-the-art light microscopy images of organoids clustered manually by biologists.

GRK 2802: Vaporization of Vanadium Pentoxide from Iron and Steel-Making Slags

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.dc.description.abstract[].value
Vanadium is present in increased amounts in slag because of the production of certain steel grades and manufacturing technologies. In terms of circular economy, vanadium should be recovered from the slag, to use it again as an alloying element. Only a few studies on the extraction of vanadium have been carried out with synthetic slags. The core of this study is the characterisation of the extraction behaviour of vanadium by evaporation of its oxides from real iron and steel-making slags. The effect of various influencing factors on the evaporation behaviour of the slags should be demonstrated. The evaluation of the results should also take crucible wear into account. In addition, the phases formed in the slag are to be analysed. For this purpose, several melting tests are carried out with different blast furnace slags. To determine the vaporised components, the slags are analysed by an X-ray fluorescence spectrometer.

GRK 2802: Vaporization of Vanadium Pentoxide from Iron and Steel-Making Slags

# _embedded.searchResult._embedded.objects[]._embedded.indexableObject.metadata.opara.project.description[].value
The focus of this doctoral project is to investigate the interaction of electrical steels (transformer steels), with high-silicate purity ladle slags free of running slag, with MgO-C products based on recyclates and environmentally friendly binders. The formation of ladle glaze can be studied by immersing a MgO-C product in a tracer-labelled slag during an immersion test. Investigations of the thermophysical properties of the liquid, killed/unkilled electrical steels and liquid slag as a function of temperature and SiO2 content, combined with thermodynamic calculations using FactSage software, make it possible to determine their influence on the interaction with MgO-C and ladle glaze formation. The influence of ladle glaze on the oxidic inclusion population, on the pick-up effect (undesirable increase of alloying elements) and reoxidation of the alloying elements is investigated by ladle glaze dissolution in the electric steel melt accompanied by chemical analysis and optical microscopy in combination with AFA (Automatic Feature Analysis) in the P-SEM. Research into the effect of the oxidic, non-metallic inclusions that form from ladle glaze on clogging in the spout nozzle based on recycled Al2O3-C is another focus.

Proton therapy requires range verification in order to exploit its full potential. One of the most promising approaches is to monitor prompt gamma-rays produced by nuclear interactions of the therapeutic particles in the patient tissues. In our paper, we test PETsys electronics with a detector with a wide energy range from 100 keV to 15 MeV. We tested what time resolution we could achieve as a high time resolution is required to achieve millimetric precision in the proton range. PETsys should survive high count rates and the fraction of pile-up events should be low or separatable. We are investigating a full acceptance approach with increased granularity in order to reduce the size of the scintillators and consequently the count rate per channel. Ideally, we want to stack the scintillators in matrices that require suitable multi-channel photo-multipliers and a fitting acquisition system. Here, we present two geometries of CeBr3 crystals 5 × 5 × 20 mm3 and 10 × 10 × 30 mm3, together with modern silicon photo-multipliers (SiPM) adapted to work with the PETsys TOFPET2 ASIC. The TOFPET2 ASIC was developed for Time-of-Flight Positron Emission Tomography (TOF-PET) applications. Here are our data measured for the publication for time resolution and coincidence time resolution, energy resolution with AmBe source, and dead time studies.

The research field of predictive maintenance aims to develop methods that are capable of predicting component failure before it occurs. This way, maintenance can be conducted with the component is still intact, while at the same time increasing resource efficiency by exploiting the fatigue strength of the component. In order to enable predictive maintenance, sensor data of the component is required, from which the predictions can be generated. Furthermore, the individual loads acting on each component of a system depend on the operating conditions of the systems and are therefore different between different systems. Failure therefore occurs as a result of individual load histories.

Virtual sensing methods aim to predict unmeasured physical quantities from available measurement data. These methods offer significant benefits to predictive maintenance, since virtual sensors can be used to estimate quantities that are difficult to measure. In fleet situations, where many identical systems with different usage histories are monitored, virtual sensors can also be deployed as a replacement for some sensors of the system. This can be done in a data-driven manner by installing sensors for all quantities of interest at one reference system, whose measurement data is used to parameterize the virtual sensor model, so that it can then be deployed for the remaining standard systems.

In many real applications, the time to failure is in the range of years, complicating the development and validation of predictive maintenance and virtual sensing approaches. The aim of this dataset is therefore to provide a demonstrator example where failure occurs based on individual load histories. Its sensor setup is designed to provide a virtual sensor use case with independent training and testing data, so that the dataset can be used for algorithm development and benchmarking purposes.

In many real applications, the time to failure is in the range of years, complicating the development and validation of predictive maintenance and virtual sensing approaches. This dataset provides a demonstrator example where failure occurs based on individual load histories. The sensor setup consists of simple notched steel specimens, which are clamped between two servo-hydraulic cylinders of a fatigue test bench. It is designed to provide a virtual sensor use case with independent training and testing data, so that the dataset can be used for algorithm development and benchmarking purposes.

The aim of the project is to increase the availability of a tramcar fleet by evaluating standard sensors that are available in every tramcar. Insights into the condition of tramcar and track enable target-oriented fleet usage and reduce follow-up maintenance costs. The increase in rail reliability increases the acceptance of public transport among the population. Financial advantages arise for operators and users.
