Item Open Access Operational characteristics of a representative Hollow Cathode Electron Emitter (HCE) device with C12A7:e- emitter(Technische Universität Dresden, 2025-12-19) Berka, Elisabeth; Wulfkühler, Jan-Philipp; Tajmar, MartinIgnition and operation testing of the hollow cathode electron emitter (HCE) designed at the Institute of Aerospace Engineering of TUD Dresden University of Technology for the E.T.PACK-Fly in-orbit demonstration (IOD) mission with a C12A7:e- electron emitter. Testing conducted in triode mode with different laboratory electronics (e.g., 100–300 µF), krypton gas, and variable operating parameters (i.e., emission current and mass flow rate).Item Open Access Monitoring data to explore particle size distribution and elemental composition in a stormwater outlet from a German urban catchment(Technische Universität Dresden, 2025-12-19) Benisch, Jakob; Rojas-Gómez , Karen L.; Helm, Björn; Borchardt, Dietrich; Krebs, PeterThis repository presents a dataset comprising online monitoring turbidity and discharge data measured with a high temporal resolution at the stormwater outlet of a small urban catchment in Dresden, Germany. Additionally, for selected rainfall-runoff events, the following data were produced: total suspended solids concentrations and their particle size distribution (<63 µm: fine particles; >63 µm: coarse fraction), their elemental composition and organic content. The online monitoring data covers January 2018 - August 2022, whereas the sampled data were collected during September 2018 - 2021. These data are optimal for exploring flush dynamics, transport patterns of particles and particle-bound pollutants, and for developing and validating particle transport formulations in urban drainage models. This will allow a better identification of stormwater treatment and management strategies to effectively address different pollutant flushes, to support regulatory decision-making, and to minimise the impact of stormwater discharges on the receiving water bodies.Item Open Access Experimental procedure for the tests on the openLAB from 2025-05-05 to 2025-05-07(Technische Universität Dresden, 2025-12-19) Richter, Bertram; Ulbrich, Lisa; Kielreiter, Anett; Jansen, Andreas; Röder, Robert; Walker, Maria; Jesse, FrankThis dataset presents the experimental campaign and monitoring data from the openLAB research bridge, a large-scale laboratory structure located in Bautzen, Germany.

In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamics, likewise supporting system characterisation and modelling. However, limited accessibility and high costs of the analysis of stable isotopes in karst aquifers have hindered progress in karst research and impeded the accurate understanding of karst processes especially when it comes to comparative or large-scale studies. In this study, we present our workflow to compile the WoKaS-Iso database, the first extensive collection of time series data for Oxygen-18 and Deuterium isotopes in karst springs and cave drip water from diverse sources, encompassing publications, theses, reports, online archives, and collaborative initiatives worldwide. The database incorporates data sourced from 236 springs and 74 caves, comprising in total 1002 time series (381 time series for the springs and 621 time series for the cave drip water). These datasets provide coverage across significant karst regions globally, spanning China, the USA, Europe, the Middle East, and Australia. Within datasets, 79% for springs and 68% for cave drip water exhibit resolutions finer than monthly intervals. In addition, by integrating isotopic records with ancillary environmental variables including spring discharge, cave drip rate, precipitation, and rainwater isotopes, the database offers a more comprehensive perspective on hydrological behaviours in karst aquifers, hence advancing hydrogeological characterisation and modelling. The WoKaS-Iso database not only deepens the understanding of the complex systems but also promotes sustainable water resource management as well as the potential to foster collaborative research.Item Open Access Dataset for object detection of charcoal kiln sites(Technische Universität Dresden, 2025-12-18) Rünger, Carolin; Neubauer, Grit; Zamboni, Pedro; Van der Maaten-Theunissen, Marieke; Eltner, AnetteThis dataset provides a collection of processed airborne LiDAR data and associated annotations of historical charcoal kiln sites in the Erzgebirgskreis district of Saxony, Germany for object detection. The starting point is raw LiDAR data, from which a digital terrain model (DTM) was first derived. Based on this, various DTM derivatives were calculated, which are used as three-channel input data (hillshade, slope and sky-view factor) for a convolutional neural network. The dataset includes training, validation and test data, including annotations, as well as trained model weights and configuration files for inference. In addition, model predictions for test areas in the Ore Mountains (Saxony) and for the Kermeter mountain range in the Rureifel (North Rhine-Westphalia) are included. To ensure reproducibility, suitable Conda environments for training and inference with MMDetection v2.28.2 are also provided.Item Open Access Data corresponding to paper: "Investigating end-of-life allocation approaches for bituminous mixtures" by Haverkamp et al. (2025)(Technische Universität Dresden, 2025-12-16) Haverkamp, Pamela; Hartung, Felix; Traverso, Marzia; Lo Presti, DavideThis data publication contains the data related to the scientific contribution "Investigating end-of-life allocation approaches for bituminous mixtures" by Haverkamp et al. (2025) Abstract of the corresponding paper: This study examines end-of-life (EoL) allocation in Life Cycle Assessment (LCA) of bituminous mixtures, comparing four: 0:100 (EoL burdens and credits attributed to secondary material producer), EN 15804 (burden split at end-of-waste), 50:50 (burdens and credits divided equally), and Circular Footprint Formula (CFF) (allocation considering market situation). Notably, this is the first application of the CFF to bituminous mixtures. Each method is evaluated regarding recyclability, downcycling avoidance, applicability to bituminous mixtures, and loop considerations. In the case study, the 0:100 method yielded the lowest Climate Change impact (-10.7 kg CO2 eq./t), followed by EN 15804, 50:50, and CFF (65.1 kg CO2 eq./t). While 0:100 and 50:50 were the most straightforward approaches, EN 15804 and CFF were more sensitive to market conditions. Sensitivity analyses covering reclaimed asphalt content, binder availability, quality ratio, and EoL fate highlighted the importance of selecting appropriate allocation methods to ensure accurate results and support circular economy strategies.Item Open Access Data for "Exact nematic and mixed magnetic phases driven by competing orders on the pyrochlore lattice"(Technische Universität Dresden, 2025-12-12) Francini, Niccolò; Schmidt, Lukas; Janssen, Lukas; Lozano-Gómez, DanielThe archive contains the data used to construct Figs. 1, 5-8, 12-14, and 21 of the manuscript "Exact nematic and mixed magnetic phases driven by competing orders on the pyrochlore lattice" by N.

Data were acquired from six porcine cadaver sessions using a da Vinci Xi stereo endoscope and a Zivid structured-light camera, registered via optical tracking and manually curated iterative alignment methods. Three sequence types - whole deformations, incremental deformations, and moved-camera clips - probe algorithm robustness to non-rigid motion, deformation magnitude, and out-of-view updates. Each clip provides rectified stereo images, per-frame instrument masks, stereo depth, start/end structured-light point clouds, curated camera poses and camera intrinsics. In postprocessing, ICP and semi-automatic registration techniques are used to register data, and instrument masks are created. The dataset enables quantitative geometric evaluation in both visible and occluded regions, alongside photometric view-synthesis baselines. Comprising over 300,000 frames and 369 point clouds across 98 curated recordings, this resource can serve as a comprehensive benchmark for developing and evaluating non-rigid SLAM, 4D reconstruction, and depth estimation methods.Item Open Access Determination of the material behavior of asphalt using performance-oriented test methods(Technische Universität Dresden, 2025-12-09) Kamratowsky, Erik; Hartung, Felix; Leischner, Sabine; Zeißler, AlexanderThe tests carried out included a Stone Mastic Asphalt with a maximum grain size of 11 mm (SMA 11 S). Greywacke was selected as the aggregate and dolomite with 10% hydrated limestone as the filler. A polymer-modified bitumen of the type 40/80-85 A was used as the binder, and the binder content was varied from 6.0 M-% to 8.0 M-% in order to determine the optimum binder content. The SMA 11 S was mixed in the pavement laboratory of the Technical University of Dresden. For this purpose, the asphalt was mixed in a mixer. The slabs were then produced using a rolling compactor. Samples were taken from the slabs and assigned a numerical identifier according to the order in which the cores were taken. Consequently, the names of the samples do not correspond to any of the names given in the guidelines. The stiffness and fatigue behavior were determined using the indirect tensile test (according to TP Asphalt-StB 2018, Parts 24 and 26), the deformation behavior using the (uniaxial) compression test on a slim sample (according to AL DSV slim 2024), and the low-temperature behavior using the thermal stress restrained specimen Test (according to TP Asphalt-StB 2013, Part 46 A). The results of these tests are presented for all asphalt variants in this data publication. In contrast to the guideline AL DSV slim 2024, other maximum stresses were utilized in the third stage at temperatures of 30 °C and 40 °C. This enabled the assessment of greater loading on the sample, thereby providing a more accurate indication of the deformation behavior of the high-performance asphalt.Item Open Access Behavioral data from the Individuality paradigm(Technische Universität Dresden, 2025-12-08) Kempermann, GerdThe data sets contain pre-processed raw data of antenna contacts of mice cohorts living within the Individuality set-up (ColonyRack), i.e. 70 connected cages that provide one large enriched environment. The data sets contain raw and processed data from antenna contacts that the mice made across the experimental period. The R package 'ColonyTrack' (https://rupertoverall.net/ColonyTrack/) was used to generate the data, which are presented in the compressed RData format. The two files contain the data for all individual mice in the experiments of both genotypes, Cyclin D2 knockouts and wildtypes with all spatial and temporal coordinates along with the mouse IDs.Item Open Access Data from "Come fly with me" VR study on Reducing Cybersickness with Foveated Depth of Field Blur across varying Locomotion Control conditions(Technische Universität Dresden, 2025-12-03) Josupeit, Judith; Helmert, Jens; Hussain, Razeen; Solari, Fabio; Chessa, ManuelaCybersickness, which is characterized by symptoms such as general discomfort, headaches, and nausea, is a common issue in virtual reality (VR) that negatively impacts the accessibility and user experience. Foveated depth of field blur rendering (FovDof) uses the perceptual limitations of the human eye to mitigate cybersickness. However, the external validity of this countermeasure is limited. To increase the external validity, an interactive task is introduced. In addition, the study introduces two levels of locomotion control (3 vs. 6DoF). Along with subjective measures focusing on cybersickness symptoms (SSQ/MISC), objective performance measures (eye tracker sampling frequency) were analyzed. Based on valid data from 65 participants, the analysis revealed significant main effects for both rendering and locomotion control factors for the objective measures. However, the effects of the two types of measures are in opposite directions. For the subjective measures, the combination of full rendering and 3DoF locomotion control resulted in the highest cybersickness values. These results suggest that the applicability of FovDof is universal, even when a task is included, and can be implemented using other eye tracking software and hardware. However, limited customizability for VR headsets limits the applicability. In cases where full locomotion control is provided to the user, the FovDof algorithm does not have additional mitigating effects.Item Public Metadata Measurement Data for "An Analysis of Energy Efficiency Features in Intel Sapphire Rapids Processors"(Technische Universität Dresden, 2025-12-02) Schmidl, MarkusThis dataset contains performance measurement data which is used to classify internal mechanisms and characteristics that facilitate the tuning of energy efficiency on the Intel Sapphire Rapids processor generation.

The test program was structured as follows: - Day 1 (2025-05-05): Static and dynamic measurements in the reference state - Day 2 (2025-05-06): Loading of the bridge with hydraulic jacks up to the ultimate limit state - Day 3 (2025-05-07): Local damage to the prestressing tendons (cutting wires at several locations) This dataset contains pictures of cracks in the precast element (PE) 2.1 during the load test conducted on day 2. The load was applied locally to the prestressed element (PE) 2.1 (span 2, PE axis 1) using two hydraulic jacks and increased in steps up to a total of 400 kN. The pictures were taken using a Dino-Lite AM4113T digital microscope connected to a laptop running the DinoCapture 2.0 software. One set of pictures was taken for each load step, before applying the load and during the plateau of constant deflection (5 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm).Item Open Access Weigh-in-Motion and Environmental Data from a German Highway(Technische Universität Dresden, 2025-11-13) Hagmanns, Moritz Peter Mathias; Jablkowski, Boguslaw; Hartung, Felix; Fazekas, Adrian; Oeser, MarkusWeigh-in-Motion (WIM) systems capture traffic-induced loads under real driving conditions, providing valuable insights into pavement loading. This dataset was collected within the DFG Collaborative Research Center SFB/TRR 339 “Digital Twin Road” using the project’s research WIM installation on the main lane of the A1/A61 highway near Erftstadt, Germany. It originates from Kistler’s KiTraffic Digital system and includes measurements from two sensor rows (four Lineas Digital sensors, type 9181A). Over a six-month observation period in 2025, 3.26 million vehicles with a total of 9.55 million axles were recorded. Each vehicle record provides detailed information on vehicle classification, loads, geometry, and tire-patch dimensions, which are rarely available from real-world WIM systems. In addition, separate environmental factors — such as asphalt and air temperature as well as solar irradiance — were recorded. The dataset supports analyses of load distributions, traffic composition, environmental factor, and speed characteristics, contributing to data-driven modeling of infrastructure loading and digital twins of road systems.Item Open Access Additional data to the publication "Characterization of cell adhesion phenomena at the dental abutment/soft tissue interface by means of a dynamic cell culture model"(Technische Universität Dresden, 2025-11-11) Angulo Salas, Laura Natalia; Kaiser, Friederike; Harrandt, Vaclav; Mehta, Kedar; Havlica, Jaromir; Wolf-Brandstetter, CorneliaThe paper describes the development of a flow chamber model for the assessment of cell adhesion strength under variable shear stress, her shown for human gingival cells to test cell adhesion phenomena under mechanical stress.
