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, Cornelia
The 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. This model is then applied in proof of principle experiments to two surface modification types that have promising surface properties and are intended for the application in dental Two types of datasets are provided: (1) raw image sets comprising combinations of microscopy images, each accompanied by corresponding metadata, and (2) processed datasets derived from individual physico-chemical measurements or on raw images. The 2nd datatype includes either basic statistical analyses—such as the calculation of means, standard deviations, standard errors, and associated statistical tests—or more advanced analyses performed through automated image processing. For the latter, the figures presented in the publication represent the results of image analyses conducted using custom-optimized macros. Each archive for each individual figure also contains the raw images, a data analysis file that compiles the raw output data generated by ImageJ, output of statistical tests as well as the respective final graphical representation. A detailed description of the data structure and image analysis workflow is provided in the accompanying README file. The macros used for image processing are published in Supplement 2 of the original publication. However, for convenience, they are also included here as standalone text files alongside a detailed instruction how to use the macros, assembled in the respective archive folder.

Crack monitoring with DFOS: Distributed strain measurements with various DFOS/adhesive combinations and model development for strain peak prediction
(Technische Universität Dresden, 2025-07-10) Herbers, Max; Richter, Bertram; Marx, Steffen
Coherent optical frequency domain reflectometry (c-OFDR) enables continuous and automated crack monitoring in concrete structures due to its high spatial resolution and long sensing range. However, the selection of a suitable DFOS/adhesive combination (DAC) remains a key challenge and is typically based on empirical knowledge. As a result, the monitoring quality is highly dependent on the user’s experience. Inappropriate choices can result in undetected cracks, degraded signal quality, miscalculated crack widths, or even fiber breakage. This study proposes a semi-analytical model for predicting strain curves for arbitrary crack patterns, based on experimentally derived parameters, such as sensitivity, strain lag parameter, and the extent of bond disturbance due to transverse cracking. The model was validated using strain measurements from tests on reinforced concrete specimens with multiple cracks. With only a few input parameters, it enables accurate representation of crack-induced strain peaks and allows for the consideration of measurement limitations typical for c-OFDR systems. Based on this, design charts and an open source software tool were developed to support practitioners in the systematic selection of DACs, tailored to the expected crack pattern.

Data set of the energy demand and associated movement of automated storage and retrieval machines
(Technische Universität Dresden, 2024-06-24) Siegel, Armin
The database consists of measurement data from multiple pallet racking storage and retrieval machines (SRMs) and the devices from automatic small parts storage systems (ASPS). The power consumption and the distance traveled by the systems were measured during several measurement operations. There are isolated measurements for the travel and hoist mechanisms of the systems. For power measurement, the Hioki 3193 Power HiTester was used. To capture the distance to the computer, a Dimetix laser distance sensor, model FLS-C 10, was employed. To account for all components and their losses, the power was measured at the aisle connection point. Accordingly, all components of the SRMs, including their losses, were recorded. The measurement setup and detailed methodology are described in the dissertation "Minimierung der Netzanschlussleistung und des Energiebedarfs von Regalbediengerät-Lagersystemen" / "Minimization of grid connection power and energy demand in automated storage and retrieval systems" by Armin Siegel. In addition to the database, which is provided as a compressed SQL file, example queries in Matlab (R2017b) and Python 3 are included.

eBike measurements for fatigue monitoring using acceleration differences
(Technische Universität Dresden, 2025-06-26) Heindel, Leonhard; Hantschke, Peter; Kästner, Markus
In fatigue monitoring, the aim is to approximate the fatigue damage accumulation in a system, for example to schedule maintenance intelligently. Virtual sensing can be deployed to obtain the required information more efficiently by estimating them from readily available sensor data. This dataset contains acceleration and strain measurements from a sensor equipped eBike, designed to develop such methods. Using the acceleration data, the aim is to estimate the fatigue damage accumulation at the strain gauge positions. Here, the sensors are positioned such that differences between multiple acceleration sensors provide information that is related to the deformation of the eBike frame, so that a connection to strain gauge data can be established by computing differences between integrated displacement data. The dataset includes data intended for training and testing of data-driven modeling approaches, which is obtained from regular eBike usage. Additional labeled data enables the analysis of specific riding maneuvers.

Estimation of fuel storage capacity for Ammonia-Fueled Vessels
(Technische Universität Dresden, 2025-07-02) Christoff, Bruno
This dataset is part of NH3CRAFT Deliverable D5.4: Parametrized Test-Benchmark with Dataset of Desktop Studies. It was generated using a MATLAB/Simulink model developed for a digital design platform supporting the conceptual development of ammonia-fueled ships. The dataset enables parametric studies focused on estimating the ammonia fuel storage capacity and operational profiles of vessels under different scenarios. The model estimates the fuel storage capacity considering the vessel’s operational profile, the vessel’s available installation spaces, and tank configuration options. The operational profile includes engine power, vessel speed, and days of operation. The vessel dimensions take into account the available installation spaces and the breadth of the vessel. Several tank configuration options are explored, including the use of Twenty-foot Equivalent Unit (TEU) and Forty-foot Equivalent Unit (FEU) tanks—made of either metallic or composite materials—and placement strategies such as horizontal placement (with and without stacking allowance) and vertical placement. The key outputs include the tank capacity per installation space in cubic meters, the vessel range (or coverage) per installation space in nautical miles, and the number of tanks per installation space. vessel range per installation space (nautical miles), and the number of tanks per installation space

Human Expertise vs. Artificial Intelligence: New evidence on building age estimation - Experts survey and ChatGPT answers
(Technische Universität Dresden, 2025-06-03) Soot, Matthias; Kretzschmar, Daniel; Eberwein, Johannes; Zaddach, Sebastian; Teuber, Andreas; Weitkamp, Alexandra
The construction, operation, and demolition of buildings account for a significant portion of global energy demand and CO2 emissions. Preserving existing buildings and encouraging renovation is crucial for sustainability. However, detailed information about the construction age of buildings is sparse. This study explores the potential of large pre-trained visual language models (VLMs) like ChatGPT to estimate building age, comparing their accuracy to that of real estate experts. The research involves a comprehensive survey of experts and the application of ChatGPT promts to a dataset of building images. The results show that ChatGPT makes more accurate statements about the age of buildings than individual experts. Only the collective intelligence of many experts provides better results than the VLM. This suggests that VLMs should be used more extensively than before to determine the age of buildings. Using this knowledge, urban planning can be tailored more specifically to necessary renovations in order to extend the life cycles of buildings and close loops in line with the principle of circularity.

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, Peter
This 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.

Predictive maintenance demonstrator dataset with individual load histories
(Technische Universität Dresden, 2025-04-14) Heindel, Leonhard; Hantschke, Peter; Kästner, Markus
Predictive maintenance aims to develop methods that are capable of predicting component failure before it occurs. Virtual sensing methods 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 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.

Räumliche Linienführung von Autobahnen
(Technische Universität Dresden, 2024-08-07) Wittig, Janette
Nach den Richtlinien für die Anlage von Autobahnen (RAA) sollen Autobahnen ihre raumordnerische Funktion mit einem hohen Maß an Verkehrssicherheit und -qualität erfüllen. Der räumliche Verlauf der Straße hat dabei einen maßgebenden Einfluss auf das Fahrverhalten der Verkehrsteilnehmer. Für Autobahnen liegen bisher nur wenige Erkenntnisse zur räumlichen Linienführung vor. Die umfangreichen Ergebnisse aus den Untersuchungen für Landstraßen sind nicht ohne weiteres auf Autobahnen übertragbar. Daher wurden auch die Inhalte der RAA zur räumlichen Linienführung zunächst vorrangig über Erfahrungen und Festlegungen erarbeitet. Ziel dieser Arbeit war die Durchführung einer Grundlagenforschung zu Defiziten in der räumlichen Linienführung von Autobahnen. Die Analyse und die Bewertung der Defizite erfolgte über simulierte und reale Strecken. Für einen Teil der Defizite lagen geometrische Modelle vor bzw. konnten erstellt werden. Über die Modelle wurde berechnet, bei welcher Kombination der Entwurfsparameter der Achse, der Gradiente und des Querschnitts das entsprechende Defizit auftritt. Aus den Ergebnissen wurden quantitative Entwurfsvorgaben zur Vermeidung des entsprechenden Defizits abgeleitet. Für alle zu untersuchenden Defizite wurden über die Straßenentwurfssoftware card_1 simulierte Strecken erstellt. Für jedes Defizit wurden die Entwurfselemente einzeln, nacheinander und unter Konstanthaltung der anderen maßgebenden Entwurfselemente so lange variiert, bis sich das Defizit einstellt bzw. das Defizit nicht mehr auftrat. Zur Bewertung und zum Vergleich der Elementkombinationen wurden Perspektivbilder gemäß den Festlegungen der Hinweise zur Visualisierung von Entwürfen für außerörtliche Straßen (H ViSt) erstellt. Über card_1 können Sichtschattenbänder gemäß den H ViSt generiert werden. Aus den Ergebnissen der über card_1 erstellten simulierten Strecken konnten somit für die Defizite Sichtschatten und verdeckter Kurvenbeginn quantitative Entwurfsvorgaben abgeleitet werden. Die anderen Defizite wurden über Perspektivbilder bewertet. Es erfolgten Probandenbefragungen, um im Ergebnis qualitative und Richtwerte für quantitative Entwurfsvorgaben ableiten zu können. Neben der Analyse von simulierten Strecken wurden auch deutschlandweit bestehende Autobahnen auf potentielle Defizite in der räumlichen Linienführung untersucht. Für die maßgebenden Abschnitte freier Strecke wurden Bänder für die Qualität der Sicht (QuaSi-Bänder) erstellt. Dies erfolgte durch das Karlsruher Institut für Technologie (KIT). Über die QuaSi-Bänder wurden folgende Bewertungskriterien ausgewertet: vorhandene Sichtweiten, Sichtschattentiefen, Sicht auf vorausliegende Lageplankrümmungswechsel und relativ sichtbare Fahrbahnoberflächen. Über die Bewertungskriterien konnte festgestellt werden, wie hoch die Anteile an Abschnitten mit und ohne Defiziten in der räumlichen Linienführung sind. Weiterhin wurde analysiert, wie stark die Defizite ausgeprägt sind und welche Trassierungselemente an diesen Stellen vorliegen. Durch eine Unfallanalyse wurde ermittelt, ob die festgestellten Defizite sicherheitsrelevant sind. Die Inhalte der Ziffer 5.4 „Räumliche Linienführung“ und der Ziffer 5.5 „Haltesichtweite“ der RAA sollten aufbauend auf den Ergebnissen fortgeschrieben und ergänzt werden. Für die H ViSt besteht kein Änderungsbedarf. Im Ergebnis der Untersuchung wurde ein Textvorschlag für die Ziffer 5.4 und die Ziffer 5.5 erarbeitet. In Ziffer 5.4 wird auf die H ViSt insofern verwiesen, dass die dort enthaltenen Hinweise zur Visualisierung und zur Nutzung des Sichtschattenbandes uneingeschränkt auch für Autobahnen gelten. Der Textvorschlag wurde vom Arbeitsausschuss 2.1 „Autobahnen“ der Forschungsgesellschaft für Straßen- und Verkehrswesen e. V. (FGSV) für die Überarbeitung der RAA diskutiert und für die Übernahme in die fortgeschriebenen Entwurfsrichtlinien empfohlen.

Raw data from the operational modes demonstration of storage tanks and auxiliary systems for ships burning ammonia as fuel
(Technische Universität Dresden, 2025-06-12) Markakis, Nikolaos
This dataset contains raw live monitoring data from the final demonstration of the NH3CRAFT project, during which various operational modes were tested. The focus was on monitoring the transfer of ammonia between tanks and evaluating the performance of associated systems, including flowmeters, valves, pumps, and key tank instrumentation such as temperature, pressure, and filling levels. The onshore demonstration involved three metallic tanks (MU1, MU2, and MC3) with capacities of 290, 145, and 155 m³, respectively, a containerized metallic tank (MC4, 20 m³), and a container holding eight composite tanks (CC1 to CC8) with a total capacity of 11 m³. Data were acquired through digital and analog signals from field instruments connected to Programmable Logic Controllers (PLCs), which interfaced with an industrial PC for real-time monitoring. The dataset demonstrates stable system performance during ammonia transfer operations and serves as a valuable resource for assessing system reliability, safety, and efficiency in ammonia storage applications, supporting the broader objectives of the NH3CRAFT project.

SivaS Project Results: Traffic Observation Data and Exemplary Subset of Master Database
(Technische Universität Dresden, 2025-06-30) Kannan, Rajagopalan; Prokop, Günther; Kollascheck, Armin; Gerike, Regine; Stoller, André; Böhme, Tobias
This dataset comprises JSON files and .mp4 video recordings that collectively form the foundation of a centralized database for traffic observations, referred to as the SivaS Master Database. Included in the dataset are: (i) a subset of the raw traffic observation data, (ii) JSON schemas defining the standardized data structure for traffic data storage, (iii) the hierarchical folder framework for organizing such data, and (iv) an exemplary implementation of the standardized database. Given the complexity of the raw data and the substantial effort involved in converting it into the standardized structure, only a limited sample dataset was manually curated and prepared. The SivaS Master Database was created by transforming a subset of the raw traffic data collected during the project into the established database, designed to support integration from various acquisition systems. The dataset includes traffic observations obtained through three different modalities: drones, stationary pole-mounted cameras, and sensor-equipped NDS (Naturalistic Driving Study) vehicles. Specifically, it features over 60 minutes of video recordings from a junction in the city of Dresden, captured simultaneously by three stationary cameras. Additionally, it contains more than 30 minutes of drone-based video footage from two separate junctions in the city of Hoyerswerda. It also includes vehicle positioning data collected by a sensor-equipped observation vehicle, formatted according to the standardized structure, from traffic observations conducted in Hoyerswerda.
