Design engineers prepare initial concepts as 3D models. These are then simulated by computational engineers. If requirements are not met, this necessitates an iterative process that runs between the design and computation departments until a valid concept is created. Design methods such as topology optimization are often used here. The upcoming result is then attempted to be adapted to certain manufacturing processes. These iteration loops can sometimes take a very long time, since the model construction and structural optimization generate large computational efforts. The present work shows on an example a methodical approach, which represents a first proof of concept, to solving this problem, including a description of methods and techniques, as well as possible problems in a detailed analysis concerning training data for neural networks and their abstraction capabilities. It is evident that additional research work needs to be conducted for further utilization in order to address all arising questions.","lang":"eng"}]},{"department":[{"_id":"153"},{"_id":"241"}],"type":"dissertation","date_created":"2024-11-07T09:15:33Z","abstract":[{"text":"Ein Trend in der Produktion sind individualisierte Produkte und damit eine höhere Variantenvielfalt, die idealerweise durch effiziente Produktionsprozesse hergestellt werden. Effizienz bedeutet in diesem Fall, dass die Produkte kostengünstig und bedarfsgerecht hergestellt werden. Der Trend geht hierbei auch in der Massenproduktion zu einer flexiblen Produktion, um das gebundene Kapital zu reduzieren und zeitnah auf Kundenwünsche reagieren zu können. Dies führt zu einem häufigeren Umrüsten der Werkzeuge in den Maschinen und somit zu einem immer häufigeren Einrichten der Prozesse.In dieser Arbeit wird eine Systematik für ein adaptives Einrichtassistenzsystem entwickelt, welches den Maschinenbediener beim Einrichten mithilfe eines definierten Vorgehens durch den Prozess leitet. Der Bediener wird dabei unterstützt die momentane Produktqualität zu bewerten und bekommt einen quantitativen Vorschlag zur Variation der Justagemöglichkeiten. So kann der Einrichtprozess zielgerichteter und fehlerfreier durchgeführt werden. Ermöglicht wird dies durch die Abbildung des notwendigen Expertenwissens in datengetriebenen Modellen. Mithilfe des so abgebildeten Expertenwissens werden optimierte Einstellungen berechnet und am Werkzeug eingestellt. Es ist nicht davon auszugehen, dass das virtualisierte Expertenwissen die Realität allumfassend abbilden und alle akuten Umwelteinflüsse messtechnisch ermittelt werden können. Etwaige Abweichungen der Produktqualität werden direkt in der entwickelten Optimierung und bei Bedarf mithilfe der vorgeschlagenen Kompensationsstrategie eliminiert.Die Systematik wird anhand eines Folgeverbundprozesses validiert. Nach der Analyse des Prozesses werden die wesentlichen Komponenten für das System entwickelt und mithilfe von Versuchen und Simulationen die Funktionsfähigkeit erfolgreich nachgewiesen.","lang":"eng"},{"text":"A trend in production are individualized products and thus a higher number of variants, which are ideally produced by efficient production processes. In this case, efficiency means that the products are manufactured at low cost and in line with demand. This trend, flexible manufacturing, is also valid for mass production, in order to reduce tied up capital and still be able to react promptly to customer demands. This leads to more frequent retooling in the machines and thus also to an increasingly frequent setting up of the processes.In this thesis, a systematic for an adaptive set-up assistant is developed, which guides the machine operator through the process during setup. The machine operator is supported in evaluating the current product quality and receives a quantitative proposal for the variation of the adjustment possibilities. Thus, the set-up process can be carried out in a more targeted and error-free manner. This is made possible by mapping the necessary expert knowledge in data-driven models. The expert knowledge is used to calculate optimized settings and adjust them on the tool. It cannot be assumed that virtualized expert knowledge will comprehensively map reality and that all acute environmental influences can be measured. Any deviations in product quality are directly eliminated in the developed optimization and, if necessary, with a proposed compensation strategy.The system is validated with a progressive tool. After analyzing the process, the essential components for the system are developed and their functionality is successfully demonstrated by means of tests and simulations.","lang":"eng"}],"supervisor":[{"id":"552","last_name":"Trächtler","first_name":"Ansgar","full_name":"Trächtler, Ansgar"}],"citation":{"mla":"Gräler, Manuel. <i>Entwicklung adaptiver Einrichtassistenzsysteme für Produktionsprozesse</i>.

The cell set-up is suitable for using powder electrode materials. Reproducibility of our cell assembly is analyzed by preparing two cells containing hard carbon (HC) powder as working electrode and sodium metal as reference electrode. Electrochemical storage properties of HC powder electrode derived from carbonization of sustainable cellulose are studied by ssNMR. 23Na in-situ ssNMR monitors the sodiation/desodiation of a Na{\\textbar}NaPF6{\\textbar}HC cell (cell 1) over a period of 22?days, showing high cell stability. After the galvanostatic process, the HC powder material is investigated by high resolution 23Na ex-situ MAS NMR. The formation of ionic sodium species in different chemical environments is obtained. Subsequently, a second Na{\\textbar}NaPF6{\\textbar}HC cell (cell 2) is sodiated for 11?days achieving a capacity of 220?mAh/g. 23Na ex-situ MAS NMR measurements of the HC powder material extracted from this cell clearly indicate the presence of quasi-metallic sodium species next to ionic sodium species. This observation of quasi-metallic sodium species is discussed in terms of the achieved capacity of the cell as well as of side reactions of sodium in this electrode material."}],"extern":"1"},{"date_created":"2025-09-12T11:11:56Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"642"},{"_id":"61"},{"_id":"230"},{"_id":"35"},{"_id":"34"},{"_id":"429"},{"_id":"27"},{"_id":"623"}],"type":"journal_article","issue":"1","publication":"Advanced Quantum Technologies","abstract":[{"text":"<jats:title>Abstract</jats:title><jats:p>The biexciton‐exciton emission cascade commonly used in quantum‐dot systems to generate polarization entanglement yields photons with intrinsically limited indistinguishability.

Als erste Stufe kommt ein PFC-Gleichrichter zum Einsatz, der die Anforderungen an den Netzstrom bezüglich Oberschwingungsgehalt und Leistungsfaktor sicherstellt. Für die zweite Wandler-Stufe hat sich in den vergangenen Jahren ein LLC-Resonanzwandler qualifiziert, der die Ladeleistung an die Traktionsbatterie galvanisch getrennt überträgt. Der Zwischenkreis besteht aus einer Bank von Elektrolytkondensatoren, in denen die pulsierende Eingangsleistung zwischengespeichert wird. Die Kondensatoren machen einen erheblichen Teil des Lader-Volumens aus und altern schnell, was insbesondere für Ladewandler an Bord von Elektrofahrzeugen unerwünscht ist. In der vorliegenden Arbeit wird untersucht, ob diese zweistufige Struktur verworfen werden kann, indem der LLC-Resonanzwandler direkt an die gleichgerichtete Netzspannung angeschlossen wird.Zum Einsatz des LLC-Resonanzwandlers als einstufiger Ladewandler ist die Schaltung für einen großen Strom- und Spannungsbereich auszulegen. Hierfür wird in der vorliegenden Arbeit eine erweiterte Zeitbereichsanalyse erarbeitet, deren hohe Modellierungsgenauigkeit im Anschluss experimentell nachgewiesen wird. Mit Hilfe dieser Zeitbereichsanalyse werden die Belastungsgrößen des Resonanzwandlers berechnet, um hiermit eine Vorauswahl der Schaltungsparameter treffen zu können. Darauf aufbauend erfolgt die Optimierung des integrierten Transformators als Schlüsselkomponente des Ladewandlers sowie dessen prototypische Realisierung. Abschließend wird mittels Prototypen die erzielbare Leistungsdichte ermittelt. Ergebnis: Verglichen mit etablierten Ladewandlern der heutigen Elektrofahrzeuge konnte durch den einstufigen Ansatz die Leistungsdichte um ca. 53% gesteigert werden."},{"text":"Today's on-board chargers of electric vehicles typically consist of two stages which are connected via a voltage DC link. A PFC rectifier is used as the first stage which ensures that the requirements for the mains current are met with respect to harmonic content and power factor. For the second converter stage, an LLC resonant converter has qualified in recent years which transmits the charging power to the traction battery in a galvanically isolated manner. The DC link consists of a bank of electrolytic capacitors in which the pulsating input power is buffered. The capacitors occupy a large portion of the charger volume and age rapidly, which is particularly undesirable for on-board chargers in electric vehicles. In the presented work, it is investigated whether this two-stage structure can be discarded by connecting the LLC resonant converter directly to the rectified line voltage.To use the LLC resonant converter as a single-stage charger, the circuit must be designed for a wide current and voltage range. For this purpose, an extended time-domain analysis is developed in this thesis, whose high modeling accuracy is subsequently demonstrated experimentally. With the help of this time domain analysis, the stress variables of the resonant converter are calculated in order to be able to make a preselection of the circuit parameters. Based on this, the optimization of the integrated transformer as a key component of the charger is carried out as well as its prototypical realization. Finally, the achievable power density is determined by means of prototypes. Result: Compared to established on-board chargers of today's electric vehicles, the single-stage approach increased the power density by about 53%.","lang":"eng"}],"citation":{"chicago":"Keuck, Lukas. <i>Entwurf Eines Einstufigen Ladewandlers Auf Basis Eines LLC-Resonanzwandlers</i>.

In this context, wide aperture automotive radars of 1m length or more and resolution close to 0.1° in azimuth and 0.5° in elevation could be beneficial. To enable coherent processing of arrays with such large aperture, prior (i.e offline) and online calibration are necessary: channel imbalances (gains and phases) and three dimensional coordinates of transmit and receive elements need to be determined. We propose a calibration strategy based on alternating steps between the two subtasks of i) channel imbalance estimation with ‘known’ array positions, by applying a singular value decomposition to the resulting tensor calculus problem; and ii) antenna position estimation with ’known’ channel imbalances, by numerically maximizing the Bayesian posterior probability; in both cases operating on range/Doppler snapshots of disjoint targets (with potentially unknown locations). Simulation studies based on the parameters of a MIMO 8x6 linear sparse array show promising results as long as the initial position errors do not exceed half a wavelength (2mm), beyond which we observe strong effects of ambiguity. Experimental results with real measurements show that after calibration in laboratory conditions, our MIMO 8x6 demonstrator with 50cm aperture is able to resolve two targets at the same range with angular separation at least as close as 0.4°."}],"citation":{"chicago":"Greiff, Christian , David Mateos-Núñez, Renato Simoni, Maria González-Huici, Stephan Kruse, J.

We apply these operators strategically to volumetric block decompositions, so-called T-meshes or base complexes, in the context of hexahedral mesh generation. This allows circumventing the expensive and unreliable global volumetric remapping step in the versatile meshing pipeline based on 3D integer-grid maps. In essence, we reduce this step to simpler local cube mapping problems, for which reliable solutions are available. As a consequence, the robustness of the mesh generation process is increased, especially when targeting coarse or block-structured hexahedral meshes. We furthermore extend this pipeline to support feature alignment constraints, and systematically respect these throughout, enabling the generation of meshes that align to points, curves, and surfaces of special interest, whether on the boundary or in the interior of the domain.</jats:p>"}],"issue":"6","publication":"ACM Transactions on Graphics","department":[{"_id":"969"}],"type":"journal_article","date_created":"2025-06-24T07:45:44Z","intvolume":"        42","publication_status":"published","date_updated":"2025-07-14T12:47:30Z","author":[{"last_name":"Brückler","first_name":"Hendrik","full_name":"Brückler, Hendrik","id":"115694"},{"id":"114904","last_name":"Campen","orcid":"0000-0003-2340-3462","first_name":"Marcel","full_name":"Campen, Marcel"}],"publication_identifier":{"issn":["0730-0301","1557-7368"]},"year":"2023","title":"Collapsing Embedded Cell Complexes for Safer Hexahedral Meshing","doi":"10.1145/3618384","language":[{"iso":"eng"}]},{"citation":{"ama":"Hinderink S, Campen M.

The growing popularity of 3D printing has also attracted security researchers, who have analyzed possibilities for weakening 3D models or stealing intellectual property from 3D models. We extend these important aspects and provide the first comprehensive security analysis of 3D printing data formats. We performed our systematic study on the example of the 3D Manufacturing Format (3MF), which offers a large variety of features that could lead to critical attacks. Based on 3MF’s features, we systematized three attack goals: Data Exfiltration (dex), Denial of Service, and UI Spoofing (uis). We achieve these goals by exploiting the complexity of 3MF, which is based on the Open Packaging Conventions (OPC) format and uses XML to define 3D models. In total, our analysis led to 352 tests. To create and run these tests automatically, we implemented an open-source tool named 3MF Analyzer (tool), which helped us evaluate 20 applications.","lang":"eng"}],"date_created":"2023-10-11T13:42:09Z","file":[{"creator":"jrossel","date_created":"2023-10-16T03:48:08Z","file_name":"Security_Analysis_of_the_3mf_Data_Format.pdf","file_size":1054999,"access_level":"open_access","relation":"main_file","date_updated":"2024-09-05T11:14:40Z","file_id":"48065","content_type":"application/pdf"}],"department":[{"_id":"632"}],"keyword":["Data Format Security","3D Manufacturing Format","3D Printing","Additive Manufacturing"],"type":"conference"}]
