--- _id: '43228' abstract: - lang: eng text: "The computation of electron repulsion integrals (ERIs) over Gaussian-type orbitals (GTOs) is a challenging problem in quantum-mechanics-based atomistic simulations. 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 FPGA kernels deployed on 2 FPGAs outperform similar computations using the widely used libint reference on a two-socket server with 40 Xeon Gold 6148 CPU cores of the same process technology by factors up to 6.0x and on a new two-socket server with 128 EPYC 7713 CPU cores by up to 1.9x." author: - first_name: Xin full_name: Wu, Xin id: '77439' last_name: Wu - first_name: Tobias full_name: Kenter, Tobias id: '3145' last_name: Kenter - first_name: Robert full_name: Schade, Robert id: '75963' last_name: Schade orcid: 0000-0002-6268-539 - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 citation: ama: 'Wu X, Kenter T, Schade R, Kühne T, Plessl C.

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. Currently, there are no investigations in the literature on the manufacturability and mechanical properties of Fe-3Si lattice structures.\r\n" author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Pramanik S, Hoyer K-P, Schaper M.

For this purpose, dry blends of glass beads with and without organosilane coupling agents and polyamide powder were prepared and processed into tensile specimens on an EOS P396 laser sintering system. The samples were tested both in the dry state and after an accelerated conditioning in a climate chamber. Furthermore, finite element method (FEM) simulations were performed to model the extreme cases of optimum adhesion and no adhesion. By correlating the tensile tests with the simulation results and by analyzing the fracture surfaces, it was shown that the filler–matrix adhesion is sufficient in the dry state but is strongly degraded by conditioning. Even the presence of various organosilane thin films could not prevent a strong deterioration of the filler–matrix adhesion and the associated deterioration of the mechanical properties. Since a comparison with an injection-molded sample of the same polymer filler combination shows identical behavior after conditioning, it is assumed that this problem is not limited to additively manufactured parts. author: - first_name: Ivo full_name: Kletetzka, Ivo id: '50769' last_name: Kletetzka - first_name: Maren full_name: Kosanke, Maren last_name: Kosanke - first_name: Dennis full_name: Meinderink, Dennis last_name: Meinderink - first_name: Vanessa full_name: Neßlinger, Vanessa last_name: Neßlinger - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: Kletetzka I, Kosanke M, Meinderink D, Neßlinger V, Grundmeier G, Schmid H-J.

This has already been investigated intensively by various authors. However, the ageing of the material at ambient temperatures during shelf life has not been the focus so far. The need to analyse the shelf life can be derived from an ecological and economic point of view. This work is focusing on the shelf life of PA2200 (PA12). To reduce the potential influences of powder production fluctuations, two different powder batches stored for 5.5 years and 6.5 years are investigated and compared to a reference powder produced 0.5 years before these investigations. Multiple powder analyses and part characterisations have been performed. A significant yellowing and molecular chain length reduction can be derived from the measurement results. Whereas the influence on mechanical part performance was minor, the parts built with the stored powders are more yellowish. As it is most likely that this is due to the consumption of polyamide stabilisers, it can be assumed that these parts will be subject to significantly faster ageing. Therefore, it is still not recommended to use the stored powders for critical parts or light intense and humid environments. author: - first_name: Sven Helge full_name: Klippstein, Sven Helge id: '71545' last_name: Klippstein - first_name: Ivo full_name: Kletetzka, Ivo id: '50769' last_name: Kletetzka - first_name: Ilknur full_name: Sural, Ilknur last_name: Sural - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: Klippstein SH, Kletetzka I, Sural I, Schmid H-J.

However, potential costs at the side of the producer of a fake action have only rarely been investigated before. It is thus not clear yet if the benefit (i.e., slowed reactions in the observer) of performing a head fake is overestimated due to concurrently arising fake production costs (i.e., slowed performance in the producer of a head fake). Therefore, we studied potential head-fake production costs with two experiments. Novice participants were asked to generate passes to the left or right side, either with or without head fakes. In Experiment 1, these actions were determined by an auditory stimulus (i.e., a 440 Hz or 1200 Hz sinus or jigsaw wave). After an interstimulus interval (ISI) of either 0 ms, 800 ms, or 1500 ms, which served the preparation of the action, the cued action had to be executed. In Experiment 2, passing to the left or right, either with or without a head fake, was determined by a visual stimulus (i.e., a player with a red or blue jersey defending either the right or left side). After an ISI of either 0 ms, 400 ms, 800 ms, or 1200 ms, the cued action had to be executed. In both experiments, we observed higher reaction times (RTs) for passes with head fakes as compared to passes without head fakes for no and an intermediate preparation interval (from ISI 0 ms to 800 ms), but no difference for a long preparation interval (for an ISI of 1200 ms and 1500 ms). Both experiments show that generating fake actions produces performance costs, however, these costs can be overcome by a longer preparation phase before movement execution. article_number: '103045' article_type: original author: - first_name: Iris full_name: Güldenpenning, Iris id: '52931' last_name: Güldenpenning orcid: 0000-0003-0549-5543 - first_name: Matthias full_name: Weigelt, Matthias id: '36388' last_name: Weigelt - first_name: Nils Tobias full_name: Böer, Nils Tobias id: '52000' last_name: Böer orcid: 0000-0002-0236-7282 - first_name: Wilfried full_name: Kunde, Wilfried last_name: Kunde citation: ama: 'Güldenpenning I, Weigelt M, Böer NT, Kunde W.

With regard to the examination system, the shift towards output-oriented teaching is still one of the most significant challenges. Assessments have to be integrated into the teaching and learning arrangements and consistently aligned towards the intended learning outcomes. In particular, assessments should provide valid evidence that learners have acquired competences that are relevant for a specific domain. However, it seems that this didactic goal has not yet been fully achieved in modeling education in computer science. The aim of this study is to investigate whether typical task material used in exercises and exams in modeling education at selected German universities covers relevant competences required for graphical modeling. For this purpose, typical tasks in the field of modeling are first identified by means of a content-analytical procedure. Subsequently, it is determined which competence facets relevant for graphical modeling are addressed by the task types. By contrasting a competence model for modeling with the competences addressed by the tasks, a gap was identified between the required competences and the task material analyzed. In particular, the gap analysis shows the neglect of transversal competence facets as well as those related to the analysis and evaluation of models. The result of this paper is a classification of task types for modeling education and a specification of the competence facets addressed by these tasks. Recommendations for developing and assessing student's competences comprehensively are given. article_number: '7' article_type: original author: - first_name: Chantal full_name: Soyka, Chantal id: '83964' last_name: Soyka orcid: https://orcid.org/0000-0002-4881-5378 - first_name: Meike full_name: Ullrich, Meike last_name: Ullrich - first_name: Michael full_name: Striewe, Michael last_name: Striewe - first_name: Niclas full_name: Schaper, Niclas last_name: Schaper citation: ama: Soyka C, Ullrich M, Striewe M, Schaper N.

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. author: - first_name: Manuel full_name: Ott, Manuel id: '44204' last_name: Ott - first_name: Niclas full_name: Meihöfener, Niclas id: '38611' last_name: Meihöfener - first_name: Iryna full_name: Mozgova, Iryna id: '95903' last_name: Mozgova citation: ama: 'Ott M, Meihöfener N, Mozgova I.

These alloys are subjected to marine environments with a high NaCl concentration, therefore, corrosion and catastrophic failure are anticipated. So, the surface dissolution of additively manufactured FeCo samples is investigated in a quasi-in situ manner, in particular, the pitting corrosion in 5.0 wt pct NaCl solution. The local dissolution of the same sample region is monitored after 24, 72, and 168 hours. Here, the formation of rectangular and circular pits of ultra-fine dimensions (less than 0.5 µm) is observed with increasing immersion time. In addition, the formation of a corrosion-inhibiting surface layer is detected on the sample surface. Surface dissolution leads to a change in the surface structure, however, no change in grain shape or grain size is noticed. The surface topography after local dissolution is correlated to the grain orientation. Quasi-in situ analysis shows the preferential dissolution of high-angle grain boundaries (HAGBs) leading to a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs). For the FeCo sample, a potentiodynamic polarisation test reveals a corrosion potential (Ecorr) of − 0.475 V referred to the standard hydrogen electrode (SHE) and a corrosion exchange current density (icorr) of 0.0848 A/m2. Furthermore, quasi-in situ experiments showed that grains oriented along certain crystallographic directions are corroding more compared to other grains leading to a significant decrease in the local surface height. Grains with a plane normal close to the $$\\langle {1}00\\rangle$$\r\n \ \r\n ⟨\r\n 100\r\n \ ⟩\r\n \r\n direction reveal lower surface dissolution and higher corrosion resistance, whereas planes normal close to the $$\\langle {11}0\\rangle$$\r\n \ \r\n ⟨\r\n 110\r\n \ ⟩\r\n \r\n direction and the $$\\langle {111}\\rangle$$\r\n \ \r\n ⟨\r\n 111\r\n \ ⟩\r\n \r\n direction exhibit a higher surface dissolution." author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Jan Tobias full_name: Krüger, Jan Tobias id: '44307' last_name: Krüger orcid: 0000-0002-0827-9654 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer citation: ama: Pramanik S, Krüger JT, Schaper M, Hoyer K-P.

Das Belastungserleben wurde vor und nach dem Praxissemester mit Hilfe des Maslach-Burnout-Inventars (MBI-SS) erfasst. Regressionsanalysen ergaben, dass soziale und organisationale Bedingungsfaktoren kaum Unterschiede im Belastungserleben aufklären. Als einzige bedeutende Faktoren mit kleinen Effekten erwiesen sich die Fahrzeit zur Praktikumsschule und die Höhe evtl. zusätzlicher Materialkosten. Auch durch Clusteranalysen ermittelte Gruppen von hochbelasteten Studierenden zeichnen sich nicht durch spezifische soziale oder organisationale Bedingungsfaktoren aus. article_type: original author: - first_name: Christoph full_name: Vogelsang, Christoph id: '4245' last_name: Vogelsang - first_name: André full_name: Brandhorst, André last_name: Brandhorst citation: ama: Vogelsang C, Brandhorst A.
