The large parasitic output capacitance and the poor reverse-recovery behaviour of the inherent body diode of high-voltage (600 V) silicon MOSFETs require soft switching, i.e. zero-voltage switching (ZVS). Otherwise, the high turn-on switching losses would lead to excessive heating and ultimately to the destruction of the switch. Therefore, MOSFET-based LLC converters are operated in the so-called inductive region only, which enables ZVS. The use of robust and cost-effective IGBTs instead of MOSFETs is particularly advantageous for automotive applications, since in addition to high reliability low costs are an important objective here. Since IGBTs are characterized by dominant turn-off losses and generally higher switching losses compared to MOSFETs, the aim is to operate them with zero-current switching (ZCS) and at low switching frequencies below the resonance frequency. In this region also the voltage transfer characteristic is steeper, which qualifies for applications with a strongly varying input-to-output voltage ratio, such as given for automotive on-board DC-DC converters connecting the (high-voltage) traction battery with the (12 V) auxiliary battery. In this paper, a stress value analysis based on a switched-model simulation is used to design a ZCS LLC converter and take advantage of the mentioned benefits of IGBTs as well as of the steeper voltage transfer characteristic. Within this operation region below the resonance frequency, however, a new phenomenon of several current pulses occurring during a single switching period through the rectifier components may appear. Generally, in applications with high output currents a synchronous rectifier (SR) is often used to keep the conduction losses of the rectifier stage at a moderate level: Low-voltage MOSFETs, which actively need to be gated synchronously to the polarity of the current pulses, are employed then instead of more lossy rectifier diodes. However, standard SR driver ICs have been shown to be unable to properly rectify the multi-pulse output currents of the proposed LLC operation, resulting in high conduction losses of the rectifier stage. A cost-effective hardware concept is presented which ensures proper rectification by using standard SR-ICs that are actively overdriven by the converter’s central microcontroller. A 2 kW prototype for an EV on-board DC-DC converter was built to show the effectiveness of the method, documenting an increase in efficiency by up to 4.1 % compared to a purely SR-IC-based solution. Overall efficiency is very similar to that of a conventional (MOSFET-based) LLC converter so that the ZCS-operated LLC IGBT-converter represents a cost-effective alternative, which even shows 10 % less worst-case losses.","lang":"eng"}],"citation":{"apa":"Urbaneck, D., Schafmeister, F., & Böcker, J.

In practical simulations, several trillions of ERIs may have to be\r\ncomputed for every time step.\r\nIn this work, we investigate FPGAs as accelerators for the ERI computation. We use template parameters, here within the Intel oneAPI tool flow, to create customized designs for 256 different ERI quartet classes, based on their orbitals. To maximize data reuse, all intermediates are buffered in FPGA on-chip memory with customized layout. The pre-calculation of intermediates also helps to overcome data dependencies caused by multi-dimensional recurrence\r\nrelations. The involved loop structures are partially or even fully unrolled for high throughput of FPGA kernels. Furthermore, a lossy compression algorithm utilizing arbitrary bitwidth integers is integrated in the FPGA kernels. To our\r\nbest knowledge, this is the first work on ERI computation on FPGAs that supports more than just the single most basic quartet class. Also, the integration of ERI computation and compression it a novelty that is not even covered by CPU or GPU libraries so far.\r\nOur evaluation shows that using 16-bit integer for the ERI compression, the fastest FPGA kernels exceed the performance of 10 GERIS ($10 \\times 10^9$ ERIs per second) on one Intel Stratix 10 GX 2800 FPGA, with maximum absolute errors around $10^{-7}$ - $10^{-5}$ Hartree. The measured throughput can be accurately explained by a performance model.

The Ga droplets can be crystallized into GaAs quantum dots using a crystallization step under As flux. In order to model the complex process, including the masked deposition of the droplets and a reduction of their number during a thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition. The simulation has only two free model parameters: the activation energy for surface diffusion and the activation energy for thermal escape of adatoms from a droplet. Simulated droplet numbers within the opening of the aperture agree quantitatively with the experimental results down to the perfect site-control, with one droplet per aperture. However, the model parameters are different compared to those of the self-assembled droplet growth. We attribute this to the presence of the mask in close proximity to the surface, which modifies the local process temperature and the As background. This approach also explains the dependence of the model parameters on the size of the aperture."}],"date_created":"2023-08-03T11:13:28Z","status":"public","volume":13,"keyword":["General Materials Science","General Chemical Engineering"],"publication":"Nanomaterials","author":[{"last_name":"Feddersen","full_name":"Feddersen, Stefan","first_name":"Stefan"},{"last_name":"Zolatanosha","full_name":"Zolatanosha, Viktoryia","first_name":"Viktoryia"},{"first_name":"Ahmed","full_name":"Alshaikh, Ahmed","last_name":"Alshaikh"},{"first_name":"Dirk","full_name":"Reuter, Dirk","last_name":"Reuter","id":"37763"},{"full_name":"Heyn, Christian","first_name":"Christian","last_name":"Heyn"}],"publisher":"MDPI AG","doi":"10.3390/nano13030466","date_updated":"2023-08-03T11:14:10Z","language":[{"iso":"eng"}],"title":"Modeling of Masked Droplet Deposition for Site-Controlled Ga Droplets","publication_identifier":{"issn":["2079-4991"]},"publication_status":"published","department":[{"_id":"15"},{"_id":"230"}]},{"doi":"10.1002/anie.202308752","date_updated":"2023-08-03T09:01:41Z","_id":"46277","year":"2023","citation":{"short":"B.

The results show that the performance of the models\r\nincreases significantly through active learning.

For a more sustainable future, development of competitive base metal dyads is mandatory. However, the electron transfer mechanisms from the photosensitizer to the proton reduction catalyst in base metal dyads remain so far unexplored. We study a Fe-Co dyad that exhibits photocatalytic H2 production activity using femtosecond X-ray emission spectroscopy, complemented by ultrafast optical spectroscopy and theoretical time-dependent DFT calculations, to understand the electronic and structural dynamics after photoexcitation and during the subsequent charge transfer process from the FeII photosensitizer to the cobaloxime catalyst. Using this novel approach, the simultaneous measurement of the transient Kalpha X-ray emission at the iron and cobalt K-edges in a two-colour experiment is enabled making it possible to correlate the excited state dynamics to the electron transfer processes. The methodology, therefore, provides a clear and direct spectroscopic evidence of the Fe->Co electron transfer responsible for the proton reduction activity."}],"user_id":"48467","title":"Ultrafast two-colour X-ray emission spectroscopy reveals excited state landscape in a base metal dyad","author":[{"id":"78878","last_name":"Nowakowski","full_name":"Nowakowski, Michał","orcid":"0000-0002-3734-7011","first_name":"Michał"},{"id":"38352","last_name":"Huber-Gedert","full_name":"Huber-Gedert, Marina","first_name":"Marina"},{"last_name":"Elgabarty","id":"60250","first_name":"Hossam","orcid":"0000-0002-4945-1481","full_name":"Elgabarty, Hossam"},{"last_name":"Kubicki","first_name":"Jacek","full_name":"Kubicki, Jacek"},{"last_name":"Kertem","full_name":"Kertem, Ahmet","first_name":"Ahmet"},{"full_name":"Lindner, Natalia","first_name":"Natalia","last_name":"Lindner"},{"last_name":"Khakhulin","first_name":"Dimitry","full_name":"Khakhulin, Dimitry"},{"last_name":"Lima","first_name":"Frederico Alves","full_name":"Lima, Frederico Alves"},{"last_name":"Choi","full_name":"Choi, Tae-Kyu","first_name":"Tae-Kyu"},{"full_name":"Biednov, Mykola","first_name":"Mykola","last_name":"Biednov"},{"last_name":"Piergies","first_name":"Natalia","full_name":"Piergies, Natalia"},{"last_name":"Zalden","first_name":"Peter","full_name":"Zalden, Peter"},{"full_name":"Kubicek, Katerina","first_name":"Katerina","last_name":"Kubicek"},{"first_name":"Angel","full_name":"Rodriguez-Fernandez, Angel","last_name":"Rodriguez-Fernandez"},{"last_name":"Salem","full_name":"Salem, Mohammad Alaraby","first_name":"Mohammad Alaraby"},{"full_name":"Kühne, Thomas","first_name":"Thomas","id":"49079","last_name":"Kühne"},{"first_name":"Wojciech","full_name":"Gawelda, Wojciech","last_name":"Gawelda"},{"orcid":"0000-0002-9294-6076","full_name":"Bauer, Matthias","first_name":"Matthias","id":"47241","last_name":"Bauer"}],"department":[{"_id":"35"},{"_id":"306"}],"publication":"arxiv","status":"public","date_created":"2023-01-30T16:08:46Z"},{"date_updated":"2023-08-10T08:34:04Z","doi":"10.1007/978-3-031-38271-0_57","oa":"1","series_title":"Lecture Notes in Computer Science (LNCS)","language":[{"iso":"eng"}],"external_id":{"arxiv":["2302.08232 "]},"title":"Learning discrete Lagrangians for variational PDEs from data and detection of travelling waves","related_material":{"link":[{"url":"https://github.com/Christian-Offen/LagrangianDensityML","relation":"software","description":"GitHub"}]},"department":[{"_id":"636"}],"publication_identifier":{"eisbn":["978-3-031-38271-0"]},"publication_status":"published","editor":[{"last_name":"Nielsen","first_name":"F","full_name":"Nielsen, F"},{"full_name":"Barbaresco, F","first_name":"F","last_name":"Barbaresco"}],"conference":{"location":"Saint-Malo, Palais du Grand Large, France","name":" GSI'23 6th International Conference on Geometric Science of Information","start_date":"2023-08-30","end_date":"2023-09-01"},"_id":"42163","intvolume":" 14071","page":"569-579","type":"conference","citation":{"chicago":"Offen, Christian, and Sina Ober-Blöbaum. “Learning Discrete Lagrangians for Variational PDEs from Data and Detection of Travelling Waves.” In Geometric Science of Information, edited by F Nielsen and F Barbaresco, 14071:569–79.

Increasing resource efficiency is a major challenge and affects almost every aspect of social and economic life. The mobility sector in particular is responsible for a large share of primary energy consumption and is increasingly in the focus of public interest. One possibility to adress these challenges is to reduce the vehicle weight by means of lightweight construction technologies such as multi-material systems. These assemblies consist of workpieces with different mechanical and geometrical properties, which poses a major challenge for joining technology. Mechanical joining processes such as semi-tubular self-piercing riveting are often used in the production of these assemblies, but due to their process characteristics, they are rigid and can only react to changing process variables to a limited extent. One way to increase the versatility of self-piercing riveting is to superimpose a tumbling kinematics on the punch. During tumbling, an angular offset of the punch axis to the tool axis is set and the contact area between punch and workpiece is reduced. In this work, investigations were carried out to determine how the tumbling strategy, consisting of the parameters tumbling angle, tumbling onset and tumbling kinematics, affects the material flow of the rivet element. For this purpose, experimental tests are conducted with the typical materials of conventional multi-material systems and the geometric joint formations are determined by means of macrographs.

Complex applications with high demands on safety and reliability, such as autonomous driving, are simultaneously driving the requirements for test and diagnosis of VLSI circuits. Throughout the life cycle of a microchip, uncertainties occur that affect its timing behavior. For example, weak circuit structures, aging effects, or process variations can lead to a change in the timing behavior of the circuit. While these uncertainties do not necessarily lead to a change of the functional behavior, they can lead to a reliability problem.\r\nWith modular and hybrid compaction two test instruments are presented in this work that can be used for X-tolerant test response compaction in the built-in Faster-than-At-Speed Test (FAST) which is used to detect uncertainties in VLSI circuits. One challenge for test response compaction during FAST is the high and varying X-rate at the outputs of the circuit under test. By dividing the circuit outputs into test groups and separately compacting these test groups using stochastic compactors, the modular compaction is able to handle these high and varying X-rates.\r\nTo deal with uncertainties on logic interconnects, a method for distinguishing crosstalk and process variation is presented. In current semiconductor technologies, the number of parasitic coupling capacitances between logic interconnects is growing. These coupling capacitances can lead to crosstalk, which causes increased current flow in the logic interconnects, which in turn can lead to increased electromigration. In the presented method, delay maps describing the timing behavior of the circuit outputs at different operating points are used to train artificial neural networks which classify the tested circuits into fault-free and faulty.","lang":"eng"},{"text":"Immer größere Anforderungen an die Leistungsfähigkeit von Mikrochips führen zu Halbleitertechnologien mit immer kleiner werdenden Strukturgrößen.

So können z.B. schwache Schaltungsstrukturen, Alterungseffekte oder Prozessvariationen zu einer Veränderung des Zeitverhaltens führen. Während diese Unsicherheiten nicht zu einer Veränderung des funktionalen Verhaltens führen müssen, können sie jedoch zu einem Zuverlässigkeitsproblem führen.\r\nMit der modularen und der hybriden Kompaktierung werden in dieser Arbeit zwei Testinstrumente vorgestellt, die für die X-tolerante Testantwortkompaktierung im eingebauten Hochgeschwindigkeitstest verwendet werden können. Eine Herausforderung für die Testantwortkompaktierung während des Hochgeschwindigkeitstests ist die hohe und variierende X-Rate an den Ausgängen der zu testenden Schaltung. Durch die Einteilung der Schaltungsausgänge in Prüfgruppen und die separierte Kompaktierung der Prüfgruppen mithilfe von stochastischen Kompaktierern, können die vorgestellten Verfahren diese hohen und variierenden X-Raten verarbeiten.\r\nFür den Umgang mit Unsicherheiten auf Verbindungsleitungen der Logik-Schaltung wird ein Verfahren zur Unterscheidung von Übersprechen und Prozessvariation vorgestellt. In aktuellen Halbleitertechnologien kommt es vermehrt zu parasitären Koppelkapazitäten zwischen den Verbindungsleitungen. In dem vorgestellten Verfahren werden künstliche neuronale Netze trainiert, um die Schaltungen in fehlerfrei und fehlerhaft zu klassifizieren.","lang":"ger"}],"extern":"1","user_id":"22707","main_file_link":[{"open_access":"1","url":"https://nbn-resolving.org/urn:nbn:de:hbz:466:2-45493"}],"supervisor":[{"full_name":"Hellebrand, Sybille","orcid":"0000-0002-3717-3939","first_name":"Sybille","id":"209","last_name":"Hellebrand"},{"first_name":"Marco","full_name":"Platzner, Marco","last_name":"Platzner","id":"398"}],"citation":{"ieee":"A.

We achieved these quantum dots by local droplet etching via InAl droplets in an In0.52Al0.48As layer and subsequent filling of the holes with In0.53Ga0.47As. Here, we present detailed investigations of the hole morphologies measured by atomic force microscopy. Statistical analysis of a set of nanoholes reveals a high degree of symmetry for nearly half of them when etched at optimized temperatures. Overgrowth with 50–150 nm In0.52Al0.48As increases their diameter and elongates the holes along the [01̄1]-direction. By systematically scanning the parameter space, we were able to fill the holes with In0.53Ga0.47As, and by capping the filled holes and performing photoluminescence measurements, we observe photoluminescence emission in the O-band up into the C-band depending on the filling height of the nanoholes.","lang":"eng"}],"user_id":"37763"},{"department":[{"_id":"302"}],"publication_status":"published","publication_identifier":{"issn":["0368-2048"]},"title":"UV-enhanced environmental charge compensation in near ambient pressure XPS","language":[{"iso":"eng"}],"date_updated":"2023-08-11T14:13:19Z","doi":"10.1016/j.elspec.2023.147317","author":[{"first_name":"Hendrik","full_name":"Müller, Hendrik","last_name":"Müller"},{"first_name":"Christian","full_name":"Weinberger, Christian","last_name":"Weinberger","id":"11848"},{"full_name":"Grundmeier, Guido","first_name":"Guido","id":"194","last_name":"Grundmeier"},{"first_name":"Maria Teresa","full_name":"de los Arcos de Pedro, Maria Teresa","last_name":"de los Arcos de Pedro","id":"54556"}],"publisher":"Elsevier BV","keyword":["Physical and Theoretical Chemistry","Spectroscopy","Condensed Matter Physics","Atomic and Molecular Physics","and Optics","Radiation","Electronic","Optical and Magnetic Materials"],"publication":"Journal of Electron Spectroscopy and Related Phenomena","volume":264,"status":"public","date_created":"2023-08-11T14:11:57Z","user_id":"54556","citation":{"mla":"Müller, Hendrik, et al. “UV-Enhanced Environmental Charge Compensation in near Ambient Pressure XPS.” Journal of Electron Spectroscopy and Related Phenomena, vol. 264, 147317, Elsevier BV, 2023, doi:10.1016/j.elspec.2023.147317.","bibtex":"@article{Müller_Weinberger_Grundmeier_de los Arcos de Pedro_2023, title={UV-enhanced environmental charge compensation in near ambient pressure XPS}, volume={264}, DOI={10.1016/j.elspec.2023.147317}, number={147317}, journal={Journal of Electron Spectroscopy and Related Phenomena}, publisher={Elsevier BV}, author={Müller, Hendrik and Weinberger, Christian and Grundmeier, Guido and de los Arcos de Pedro, Maria Teresa}, year={2023} }","apa":"Müller, H., Weinberger, C., Grundmeier, G., & de los Arcos de Pedro, M.

This study could lead to the successful processing of squirrel cage conductors (a lattice structure by design) of an induction motor by additive manufacturing in the future.\r\n\r\n\r\nDesign/methodology/approach\r\nThe compression behaviour of two lattice structures where struts are arranged in a face-centred cubic position and vertical edges (FCCZ), and struts are placed at body-centred cubic (BCC) positions, prepared by laser powder bed fusion (LPBF), is explored. The experimental investigations are supported by finite element method (FEM) simulations.\r\n\r\n\r\nFindings\r\nThe FCCZ lattice structure presents a peak in the stress-strain curve, whereas the BCC lattice structure manifests a plateau. The vertical struts aligned along the compression direction lead to a significant increase in the load-carrying ability of FCCZ lattice structures compared to BCC lattice structures. This results in a peak in the stress-strain curve. However, the BCC lattice structure presents the bending of struts with diagonal struts carrying the major loads with struts near the faceplate receiving the least load. A high concentration of geometrically necessary dislocations (GNDs) near the grain boundaries along cell formation is observed in the microstructure.\r\n\r\n\r\nOriginality/value\r\nTo the best of the authors’ knowledge, this is the first study on additive manufacturing of Fe-3Si lattice structures.

Geospatial link discovery algorithms have to deal with millions of point sets containing billions of points. \r\nMethodology: To speed up the discovery of geospatial links, we propose COBALT. COBALT combines the content measures with R-tree indexing. The content measures are based on the area, diagonal and distance of the minimum bounding boxes of the polygons which speeds up the process but is not perfectly accurate. We thus propose two polygon splitting approaches for improving the accuracy of COBALT. \r\nFindings: Our experiments on real-world datasets show that COBALT is able to speed up the topological relation discovery over geospatial KGs by up to 1.47 × 104 times over state-of-the-art linking algorithms while maintaining an F-Measure between 0.7 and 0.9 depending on the relation. Furthermore, we were able to achieve an F-Measure of up to 0.99 by applying our polygon splitting approaches before applying the content measures. \r\nValue: The process of discovering links between geospatial resources can be significantly faster by sacrificing the optimality of the results. This is especially important for real time data-driven applications such as emergency response, location-based services and traffic management. In future work, additional measures, like the location of polygons or the name of the entity represented by the polygon, could be integrated to further improve the accuracy of the results.","lang":"eng"}]},{"status":"public","date_created":"2023-08-16T08:57:39Z","publication_status":"published","publication_identifier":{"issn":["2169-3536"]},"publisher":"Institute of Electrical and Electronics Engineers (IEEE)","author":[{"last_name":"Ahmed","full_name":"Ahmed, Abdullah Fathi","first_name":"Abdullah Fathi"},{"full_name":"Sherif, Mohamed Ahmed","first_name":"Mohamed Ahmed","last_name":"Sherif"},{"last_name":"Ngomo","first_name":"Axel-Cyrille Ngonga","full_name":"Ngomo, Axel-Cyrille Ngonga"}],"publication":"IEEE Access","keyword":["General Engineering","General Materials Science","General Computer Science","Electrical and Electronic Engineering"],"user_id":"67234","title":"NELLIE: Never-Ending Linking for Linked Open Data","citation":{"ama":"Ahmed AF, Sherif MA, Ngomo A-CN.

Declarative link discovery frameworks use complex link specifications to express the conditions under which a link between two resources can be deemed to exist. However, understanding such complex link specifications is a challenging task for non-expert users of link discovery frameworks. In this paper, we address this drawback by devising NMV-LS, a language model-based verbalization approach for translating complex link specifications into natural language. NMV-LS relies on the results of rule-based link specification verbalization to apply continuous training on T5, a large language model based on the Transformerarchitecture. We evaluated NMV-LS on English and German datasets using well-known machine translation metrics such as BLUE, METEOR, ChrF++ and TER. Our results suggest that our approach achieves a verbalization performance close to that of humans and outperforms state of the art approaches.
