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."},{"lang":"eng","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%."}],"citation":{"ama":"Keuck L. <i>Entwurf Eines Einstufigen Ladewandlers Auf Basis Eines LLC-Resonanzwandlers</i>.

Existing work on the automatic generation of natural language counter-arguments does not address the relation to the conclusion, possibly because many arguments leave their conclusion implicit. In this paper, we hypothesize that the key to effective counter-argument generation is to explicitly model the argument‘s conclusion and to ensure that the stance of the generated counter is opposite to that conclusion. In particular, we propose a multitask approach that jointly learns to generate both the conclusion and the counter of an input argument. The approach employs a stance-based ranking component that selects the counter from a diverse set of generated candidates whose stance best opposes the generated conclusion. In both automatic and manual evaluation, we provide evidence that our approach generates more relevant and stance-adhering counters than strong baselines."}],"project":[{"name":"TRR 318 - INF: TRR 318 - Project Area INF","_id":"118"}],"place":"Dubrovnik, Croatia","date_created":"2025-02-20T08:20:35Z","type":"conference","department":[{"_id":"600"},{"_id":"660"}],"status":"public","year":"2023","title":"Conclusion-based Counter-Argument Generation","author":[{"id":"73059","full_name":"Alshomary, Milad","first_name":"Milad","last_name":"Alshomary"},{"id":"3900","first_name":"Henning","last_name":"Wachsmuth","full_name":"Wachsmuth, Henning"}],"date_updated":"2025-02-20T08:21:41Z","page":"957–967","_id":"58723","publisher":"Association for Computational Linguistics","language":[{"iso":"eng"}],"doi":"10.18653/v1/2023.eacl-main.67","user_id":"3900","editor":[{"first_name":"Andreas","last_name":"Vlachos","full_name":"Vlachos, Andreas"},{"full_name":"Augenstein, Isabelle","last_name":"Augenstein","first_name":"Isabelle"}]},{"date_updated":"2025-02-25T05:52:16Z","title":"Calibration of Large Coherent MIMO Radar Arrays: Channel Imbalances and 3D Antenna Positions","status":"public","year":"2023","conference":{"end_date":"2023.05.26","location":"Berlin, Germany","name":"2023 24th International Radar Symposium (IRS)","start_date":"2023.05.24"},"author":[{"full_name":"Greiff, Christian ","last_name":"Greiff","first_name":"Christian "},{"first_name":"David","last_name":"Mateos-Núñez","full_name":"Mateos-Núñez, David"},{"full_name":"Simoni, Renato","first_name":"Renato","last_name":"Simoni"},{"first_name":"Maria","last_name":"González-Huici","full_name":"González-Huici, Maria"},{"id":"38254","last_name":"Kruse","first_name":"Stephan","full_name":"Kruse, Stephan"},{"id":"37144","orcid":"0000-0002-5950-6618 ","last_name":"Scheytt","first_name":"J.

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°.","lang":"eng"}],"publication":"2023 24th International Radar Symposium (IRS)","citation":{"bibtex":"@inproceedings{Greiff_Mateos-Núñez_Simoni_González-Huici_Kruse_Scheytt_Kolk_Höller_Kurz_Meinecke_et al._2023, title={Calibration of Large Coherent MIMO Radar Arrays: Channel Imbalances and 3D Antenna Positions}, DOI={<a href=\"https://doi.org/10.23919/IRS57608.2023.10172475\">10.23919/IRS57608.2023.10172475</a>}, booktitle={2023 24th International Radar Symposium (IRS)}, publisher={IEEE}, author={Greiff, Christian  and Mateos-Núñez, David and Simoni, Renato and González-Huici, Maria and Kruse, Stephan and Scheytt, J.

Adaptive local refinement of the mesh is performed to facilitate this process. We describe a prototype algorithm in the realm of this framework for the computation of maps from ball-topology tetrahedral meshes to convex or star-shaped domains. This algorithm is evaluated and compared to state-of-the-art methods, demonstrating its benefits in terms of bijectivity. We also discuss the associated cost in terms of sometimes significant mesh refinement to obtain the necessary degrees of freedom required for establishing a valid mapping. Our conclusions include that while this algorithm is only of limited immediate practical utility due to efficiency concerns, the general framework has the potential to inspire a range of novel methods improving on the efficiency aspect.\r\n          </jats:p>"}],"extern":"1","date_created":"2025-06-23T10:58:12Z","department":[{"_id":"969"}],"type":"journal_article","author":[{"full_name":"Nigolian, Valentin Zénon","first_name":"Valentin Zénon","last_name":"Nigolian"},{"full_name":"Campen, Marcel","orcid":"0000-0003-2340-3462","first_name":"Marcel","last_name":"Campen","id":"114904"},{"full_name":"Bommes, David","last_name":"Bommes","first_name":"David"}],"publication_identifier":{"issn":["0730-0301","1557-7368"]},"year":"2023","title":"Expansion Cones: A Progressive Volumetric Mapping Framework","intvolume":"        42","date_updated":"2025-07-14T12:47:55Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1145/3592421"},{"language":[{"iso":"eng"}],"doi":"10.1145/3618384","title":"Collapsing Embedded Cell Complexes for Safer Hexahedral Meshing","year":"2023","author":[{"id":"115694","first_name":"Hendrik","last_name":"Brückler","full_name":"Brückler, Hendrik"},{"last_name":"Campen","orcid":"0000-0003-2340-3462","first_name":"Marcel","full_name":"Campen, Marcel","id":"114904"}],"publication_identifier":{"issn":["0730-0301","1557-7368"]},"publication_status":"published","date_updated":"2025-07-14T12:47:30Z","intvolume":"        42","date_created":"2025-06-24T07:45:44Z","type":"journal_article","department":[{"_id":"969"}],"issue":"6","publication":"ACM Transactions on Graphics","extern":"1","abstract":[{"text":"<jats:p>We present a set of operators to perform modifications, in particular collapses and splits, in volumetric cell complexes which are discretely embedded in a background mesh.

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"}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://dl.acm.org/doi/abs/10.1145/3607199.3607216"}],"doi":"10.1145/3607199.3607216","author":[{"first_name":"Jost","last_name":"Rossel","orcid":"0000-0002-3182-4059","full_name":"Rossel, Jost","id":"58331"},{"first_name":"Vladislav","last_name":"Mladenov","full_name":"Mladenov, Vladislav"},{"id":"83504","full_name":"Somorovsky, Juraj","last_name":"Somorovsky","first_name":"Juraj","orcid":"0000-0002-3593-7720"}],"title":"Security Analysis of the 3MF Data Format","year":"2023","date_updated":"2025-07-16T11:06:49Z","publication_status":"published"},{"oa":"1","citation":{"bibtex":"@inproceedings{Terfloth_Schaffer_Buhl_Schulte_2023, title={Adding Why to What?

But such explanations between humans vary greatly, making it difficult to research commonalities across explanations. We used the dual nature theory, a techno-philosophical approach, to cope with these challenges. According to it, one can explain, for example, an XAI's decision by addressing its dual nature: by focusing on the Architecture (e.g., the logic of its algorithms) or the Relevance (e.g., the severity of a decision, the implications of a recommendation). We investigated 20 game explanations using the theory as an analytical framework. We elaborate how we used the theory to quickly structure and compare explanations of technological artifacts. We supplemented results from analyzing the explanation contents with results from a video recall to explore how explainers justified their explanation. We found that explainers were focusing on the physical aspects of the game first (Architecture) and only later on aspects of the Relevance. Reasoning in the video recalls indicated that EX regarded the focus on the Architecture as important for structuring the explanation initially by explaining the basic components before focusing on more complex, intangible aspects. Shifting between addressing the two sides was justified by explanation goals, emerging misunderstandings, and the knowledge needs of the explainee. We discovered several commonalities that inspire future research questions which, if further generalizable, provide first ideas for the construction of synthetic explanations."}],"main_file_link":[{"url":"https://link.springer.com/chapter/10.1007/978-3-031-44070-0_13","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1007/978-3-031-44070-0_13","title":"Adding Why to What?
