Bei der Interaktion mit datengetriebenen Artefakten spielen Daten eine zentrale Rolle, unter anderem persönliche Daten von Schüler:innen, die solche Systeme nutzen. Aus der Perspektive informatischer Bildung besteht ein wichtiges Ziel darin, Schüler:innen zu befähigen, datengetriebene digitale Artefakte aus ihrem Alltag zu verstehen, denen gegenüber informierte und reflektierte Positionen einzunehmen und die digitale Welt aktiv mitzugestalten. Das setzt etwa voraus, dass Schüler:innen das Gelernte aus dem Informatikunterricht in ihren alltäglichen Interaktionen mit datengetriebenen digitalen Artefakten anwenden können, um sich mit diesen Artefakten und der Rolle von Daten auseinanderzusetzen und darauf aufbauend selbstbestimmt, mündig und verantwortungsvoll zu handeln. Für diese Ziele informatischer Bildung wird in dieser Arbeit das fachdidaktische Konzept Datenbewusstsein entwickelt und evaluiert. Datenbewusstsein stellt Schüler:innen ein sogenanntes Erklärmodell als Zugang zur datengetriebenen Welt bereit und zielt darauf ab, dass sie damit ihre eigene Rolle in Interaktionen mit datengetriebenen digitales Artefakten sowie die Rolle von Daten darin wahrnehmen, verstehen und reflektieren können. Dadurch soll Datenbewusstsein zu einer selbstbestimmten, mündigen und verantwortungsvollen Handlungsfähigkeit in einer datengetriebenen Welt beitragen. Die Entwicklung und Evaluation des Konzepts orientiert sich am Design-Based Research Ansatz, wofür aus informatikdidaktischer Perspektive ein eigenes Vorgehensmodell entwickelt wurde. Das Forschungsvorhaben hat zwei übergeordnete Ziele: Erstens soll eine theoretische Konzeption von Datenbewusstsein für informatische Bildung und zweitens ein didaktischer Ansatz zur Förderung von Datenbewusstsein entwickelt werden. In drei Zyklen wird die Förderung von Datenbewusstsein im Informatikunterricht mithilfe von Unterrichtsinterventionen empirisch untersucht. Schwerpunkte liegen dabei unter anderem auf dem Verständnis der Schüler:innen von der Rolle von Daten in datengetriebenen digitalen Artefakten, der Förderung ihrer Auseinandersetzung mit solchen digitalen Artefakten im Alltag sowie dem Beitrag zur Entwicklung ihrer Handlungsfähigkeit. Die Hauptergebnisse dieser Arbeit liegen in der Konzeption von Datenbewusstsein sowie im entwickelten didaktischen Ansatz zum Lernen von Erklärmodellen im Informatikunterricht. Danach lernen Schüler:innen im Unterricht ein Erklärmodell für Datenbewusstsein und wenden es auf alltägliche Beispiele für datengetriebene digitale Artefakte an. Die empirischen Ergebnisse werden zeigen, dass Schüler:innen das Erklärmodell verstehen, sie darin eine subjektive Bedeutsamkeit für ihren Alltag erkennen und es ihre Handlungsfähigkeit in alltäglichen Situationen mit datengetriebenen digitalen Artefakten fördern kann."},{"text":"Nowadays, data-driven digital artefacts have become an integral part of our everyday lives. In interactions with such artefacts, data plays a central role, including personal data of students who use these systems, for example. From the perspective of computing education, a key goal is to enable students to understand data-driven digital artefacts from their everyday lives, to adopt informed and reflected positions towards them, and to actively shape the digital world. This, in turn, requires that students are able to apply what they have learned in classes to their everyday interactions with data-driven digital artefacts, allowing them to engage critically with these artefacts and the role of data, and to act in a self-determined, agentic, and responsible way. In line with these goals of computing education, this dissertation develops and evaluates the data awareness framework (Datenbewusstsein). Data awareness provides students with an explanatory model that serves as a means of accessing the data-driven world, aiming to help them perceive, understand, and reflect on both their own role in interactions with data-driven digital artefacts and the role of data in those interactions. In doing so, data awareness aims to support students in acting in a self-determined, agentic, and responsible way in a data-driven world. The development and evaluation of the framework follows a design-based research approach, for which a specific procedural model was developed from a computing education perspective. The dissertation has two overarching goals: first, to develop a theoretical framework for data awareness in computing education, and second, to develop an educational approach for fostering students' data awareness. Over three iterative cycles, students' data awareness will be empirically examined through teaching units in computing classes. The focus lies, among other things, on students' understanding of the role of data in data-driven digital artefacts, on fostering their engagement with such artefacts in everyday life, and on contributing to the development of their agency and empowered behaviour. Two main outcomes of this dissertation are the conceptualisation of data awareness and the development of the educational approach to learning explanatory models in computing education. Accordingly, students learn an explanatory model for data awareness in teaching units and apply it to everyday examples of data-driven digital artefacts. The empirical findings will show that students understand the model, perceive it as subjectively relevant to their everyday lives, and that it can support empowered behaviour and agency.","lang":"eng"}],"citation":{"bibtex":"@book{Höper_2025, title={Entwicklung und Evaluation des Konzepts Datenbewusstsein für informatische Bildung}, DOI={<a href=\"https://doi.org/10.17619/UNIPB/1-2420\">https://doi.org/10.17619/UNIPB/1-2420</a>}, author={Höper, Lukas}, year={2025} }","ama":"Höper L. <i>Entwicklung Und Evaluation Des Konzepts Datenbewusstsein Für Informatische Bildung</i>.; 2025. doi:<a href=\"https://doi.org/10.17619/UNIPB/1-2420\">https://doi.org/10.17619/UNIPB/1-2420</a>","mla":"Höper, Lukas. <i>Entwicklung Und Evaluation Des Konzepts Datenbewusstsein Für Informatische Bildung</i>. 2025, doi:<a href=\"https://doi.org/10.17619/UNIPB/1-2420\">https://doi.org/10.17619/UNIPB/1-2420</a>.","short":"L.

Generating light that simultaneously carries high-order orbital angular momenta and exhibits quantum correlations is a challenging task. In this work, we present a theoretical approach to the generation of correlated Schmidt modes carrying OAM via parametric down-conversion (PDC) in cascaded nonlinear systems (nonlinear interferometers) pumped by Laguerre–Gaussian beams. We demonstrate how the number of generated modes and their population can be controlled by varying the pump parameters, the gain of the PDC process, and the distance between the crystals. We investigate the angular displacement measurement uncertainty of these interferometers and demonstrate that it can overcome the classical shot noise limit."}],"_id":"63744","publisher":"AIP Publishing","volume":10,"user_id":"55907","status":"public","oa":"1","citation":{"short":"D.

The precision of every EELS analysis, however, is inherently limited by noises and blur. This thesis offers a comprehensive understanding of the noise, which is particularly valuable at low dwell times necessary for beam sensitive materials and for electron-matter interactions with low frequency of occurrence, where the noise dominates the measurement. Additionally, correlations encountered in the noise of an EELS measurement are described from both a theoretical and experimental perspective. These correlations are caused by a convolution of the noisy signal with the detector point spread function. Methods for characterizing key noise parameters of typical detectors are described, allowing the noise model to be tailored to any EELS detector. Ultimately, a novel deconvolution method enabling significant sharpening and denoising of EELS measurements is introduced and demonstrated. Its efficiency is further validated on both simulation and experimental data. The described advancement offered by the proposed deconvolution method enables the extension of current electron microscope capabilities, facilitating analysis that would be unfeasible with existing deconvolution techniques."}],"related_material":{"link":[{"url":"https://doi.org/10.17619/UNIPB/1-2438","relation":"software"}]},"citation":{"mla":"Zietlow, Christian. <i>A Novel Lagrangian-Based Method for the Deconvolution of Electron Energy-Loss Spectra</i>.

The aim of the project is to investigate the influencing factors for a circular economy in the field of automotive lighting using the example of a headlamp. A key aspect is the analysis of methods for recycling end of life headlamps to recover materials for the next generation of headlamps and to evaluate their reusability. The article presents investigations and methods for recovering materials from used headlamps. These methods are evaluated based on how effectively they can recover materials for the next generation of headlamps and to what extent these materials can be reused. The goal was to identify the best practices that are both ecologically and economically sustainable. To support the development of a headlamp, a digital twin was created, which enables a detailed life cycle analysis at any time. This digital twin ensures that the expected CO2 footprint of the product can be analysed over its product life cycle during development to ensure optimal use and recycling of materials. This ensures a precise assessment of the environmental impact of future products. The final demonstrator of the project, developed based on the findings of the two points mentioned above and OEM requirements, presents the third key point of the research project: the design of a new product to enable a circular economy in the field of automotive lighting. The headlamp is designed to use circular economy recyclates and to serve as a material source at the end of its life. This represents an important step for automotive lighting towards a circular economy, where products and materials are used and reused for as long as possible."}],"citation":{"bibtex":"@inproceedings{Schmidt_Niedling_Helmig_Forbes_Jardin_Stieren_Fittkau_Peitzmeier_2025, place={Darmstadt}, title={Circular economy approaches in automotive lighting – insights from the Nalyses project}, DOI={<a href=\"https://doi.org/10.26083/tuprints-00030841\">10.26083/tuprints-00030841</a>}, booktitle={Proceedings of the 16th International Symposium on Automotive Lighting 2025}, author={Schmidt, Christian and Niedling, Mathias and Helmig, Jan and Forbes, Steffen and Jardin, Janis and Stieren, Stephan and Fittkau, Niklas and Peitzmeier, Henning}, year={2025} }","ama":"Schmidt C, Niedling M, Helmig J, et al.

Meanwhile, the existing methods of its characterization are technically complicated, which reduces the level of squeezing, and mostly deal with a single mode at a time. Here, for the first time, to the best of our knowledge, we employ optical parametric amplification to characterize multiple squeezing eigenmodes simultaneously. We retrieve the shapes and squeezing degrees of all modes at once through direct detection followed by modal decomposition. This method is tolerant to inefficient detection and does not require a local oscillator. For a spectrally and spatially multimode squeezed vacuum, we characterize eight strongest spatial modes, obtaining squeezing and anti-squeezing values of up to −5.2 ± 0.2 dB and 8.6 ± 0.3 dB, respectively, despite the 50% detection loss. This work, being the first exploration of an optical parametric amplifier’s multimode capability for squeezing detection, paves the way for the real-time detection of multimode squeezing.","lang":"eng"}],"issue":"1","publication":"Optica Quantum","type":"journal_article","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"35"},{"_id":"429"}],"date_created":"2026-01-26T15:57:13Z"},{"status":"public","volume":36,"user_id":"93720","publisher":"IOP Publishing","_id":"61825","project":[{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"},{"name":"TRR 285 - Project Area C","_id":"133"},{"_id":"149","name":"TRR 285 - Subproject C05"}],"quality_controlled":"1","citation":{"ama":"Butzhammer L, Handke N, Wittl S, Herl G, Hausotte T.

To maintain high accuracy when deviating from the established circular scan trajectory, trajectory calibration methods using multi-sphere reference objects with known marker positions are commonly employed. These multi-sphere objects can either be scanned together with the measurement object (online trajectory calibration) or in a separate scan (offline trajectory calibration). While offline calibration increases machine time, it generally results in higher scan quality. However, a sufficient pose repeatability is necessary to ensure comparable or even superior accuracy to online calibration. In this contribution, we present a straightforward procedure to compare both types of trajectory calibration in a way that the differences of the results can directly be traced back to the influence of the pose repeatability. The multi-sphere reference object is not only used for trajectory calibration, but simultaneously as a measurement object for repeated measurements. The methodology is tested on both a twin robotic CT system and a conventional CT system that is additionally equipped with a hexapod manipulator for adaptive object tilting. Results showed, independent from the type of trajectory calibration, systematic measurement errors in the order of 10<jats:sup>−5</jats:sup>–10<jats:sup>−4</jats:sup> of measured sphere distances and sphericity values below 50 <jats:inline-formula>\r\n                     <jats:tex-math/>\r\n                     <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" overflow=\"scroll\">\r\n                        <mml:mrow>\r\n                           <mml:mrow>\r\n                              <mml:mtext>μ</mml:mtext>\r\n                           </mml:mrow>\r\n                           <mml:mrow>\r\n                              <mml:mi mathvariant=\"normal\">m</mml:mi>\r\n                           </mml:mrow>\r\n                        </mml:mrow>\r\n                     </mml:math>\r\n                  </jats:inline-formula>.

Overall, both investigated systems demonstrated sufficient positioning repeatability for offline trajectory calibration. The method is in general also applicable to any other types of manipulator systems used for CT devices. It provides a workflow for the decision which type of trajectory calibration is preferable for a given CT system.</jats:p>"}],"publication":"Measurement Science and Technology","issue":"2","department":[{"_id":"630"}],"type":"journal_article","date_created":"2025-10-14T13:50:32Z"},{"user_id":"72850","ddc":["000"],"volume":173,"_id":"55620","has_accepted_license":"1","status":"public","oa":"1","file_date_updated":"2024-08-15T11:26:35Z","citation":{"ama":"Speckenmeyer P, Hilmer C, Rauchecker G, Schryen G.
