SaCs können zu einer Vielzahl an klinischen Symptomen führen. Akute und zum Teil die klinische Regeneration überdauernde parasympathische Inhibierung im Autonomen Nervensystem (ANS) wurde nach saC bereits häufig beschrieben. Über Veränderungen im sympathischen Nervensystem ist jedoch noch wenig bekannt. Diese wurden durch Messungen der elektrodermalen Aktivität (EDA) im Schlaf, der erheblich zur Regeneration nach saC beiträgt, sowie im Zusammenhang mit subjektiven Symptomen nach saC im Rahmen einer Pilotstudie untersucht. Methode 18 Sportler und Sportlerinnen mit diagnostizierter saC und 18 nach Alter, Geschlecht, Größe, Gewicht, Sportart und Leistungsklasse gematchte Kontrollathleten und -athletinnen trugen in den Nächten während der individuellen Return-to-Sport (RTS) Phase sowie drei Wochen nach Abschluss des RTS (postRTS) einen Handgelenkssensor (E4 Empatica Inc., Mailand, Italien). Anteile nächtlicher tonischer (meanEDA) und phasischer (EDRs, Schlafstürme) EDA wurden zwecks Gruppenvergleich ermittelt und mit saC-Symptomen (SCAT5) sowie dem subjektiven Erholungszustand nach Schlaf mittels Mann-Whitney U-Tests oder ungepaarten t-Tests verglichen. Ergebnisse Während und nach dem RTS konnten keine Gruppenunterschiede in den nächtlichen EDA-Parametern nachgewiesen werden. Eine höhere meanEDA während des RTS korrelierte mit einer höheren Anzahl an Symptomen (p=0,025, r=0,525) und eine erhöhte phasische EDA mit einem geringeren Anstieg des subjektiven Erholungszustands von vor zu nach Schlaf (EDRs: p=0,007, r=−0,642; EDRs/min: p>0,001, r=−0,762; Schlafstürme: p=0,011, r=−0,616). Fazit Die nächtliche EDA nach saC unterschied sich während und nach dem RTS nicht signifikant zu gematchten Kontrollsportlern und -sportlerinnen. Der Zusammenhang zwischen höherer EDA während des RTS und der Anzahl an saC-Symptomen sowie der geringeren subjektiven Erholung nach Schlaf könnte sowohl ursächlich für als auch Effekt der subjektiven Symptome sein und sollte durch Baseline-Messungen und in Kombination mit parasympathischen Markern künftig weiter untersucht werden.}}, author = {{Delling, Anne Carina and Jakobsmeyer, Rasmus and Christiansen, Nele and Coenen, Jessica and Reinsberger, Claus}}, issn = {{1613-0863}}, journal = {{B&G Bewegungstherapie und Gesundheitssport}}, keywords = {{General Medicine}}, number = {{02}}, pages = {{41--48}}, publisher = {{Georg Thieme Verlag KG}}, title = {{{Nächtliche sympathische Aktivität und subjektive Symptome nach sport-assoziierter Concussion: eine Pilotstudie}}}, doi = {{10.1055/a-2023-7579}}, volume = {{39}}, year = {{2023}}, } @misc{52251, abstract = {{Session tickets are a resumption mechanism, which can speed up repeated TLS connections.

Electronic spectra covering the spin-forbidden transitions show that the spin-flip states in mer-1, mer-2, and cisfac-[3]3+ are much lower in energy than those in comparable chromium(III) compounds. While all three complexes show weak spin-flip phosphorescence in NIR-II, the emission of cisfac-[3]3+ peaking at 1550 nm is particularly low in energy. Femtosecond transient absorption spectroscopy reveals a short excited-state lifetime of 1.4 ns, 6 orders of magnitude shorter than that of mer-[Cr(ddpd)2]3+.

The application of the mechanical joining process clinching allows the assembly of different sheet metal materials with a wide range of material thickness configurations, which is of interest for lightweight multi-material structures.

It is essential to be able to take into account the influence of the joining process-induced damage on the load-bearing capacity of the joint during the loading phase. This study presents a numerical damage accumulation in the clinching process based on an implemented Hosford-Coulomb failure model using a 3D clinching process model applied on the aluminum alloy EN AW-6014 in temper T4. A correspondence of the experimentally determined failure location with the element of the highest numerically determined damage accumulation is shown.

Joining hypoeutectic AlSi alloys constitutes a challenge because the brittle character of these cause cracks in the joint during conventional mechanical joining. Furthermore, the friction-induced heat of the novel joining process causes a finer microstructure in the hypoeutectic AlSi9 casting alloy.

Here, the low ductility of the AlSi alloys constitutes a challenge because their brittle nature causes cracks during the joining process.

For this study, we used the twin-roll casting process (TRC) with water-cooled rollers to manufacture the hypoeutectic AlSi10Mg for the first time. Hereby, high solidification rates are realisable, which introduces a microstructure that is about four times finer than in the sand casting process. In particular, it is shown that a fine microstructure close to the modification with Na or Sr is achieved by the high solidification rate in the TRC process without using these elements. Based on this, the mechanical properties increase, and especially the ductility is enhanced.

In such applications, lubricants are exposed to extreme conditions in the contact area. In lubrication gaps, the pressure can reach values up to 5 GPa. The thermophysical properties of lubricants, and in particular the viscosity, at such extreme conditions have an important influence on the friction and wear behavior of a tribosystem. Accordingly, reliable lubricant property models are a prerequisite for accurate tribological simulations, e.g. elastohydrodynamic lubrication (EHL) simulations. Presently, the vast majority of experimental thermophysical property data are only available up to 1 GPa. Thus, reliable and robust models with strong extrapolation capabilities to higher pressure are required. In this work, viscosity measurements of squalane in a temperature range be tween 20 °C and 100 °C and pressures up to 1 GPa were carried out. Based on that data, a physical model for the viscosity was developed. The model is built by combining a molecular-based equation of state with the so-called entropy scaling approach. Finally, we demonstrate how this fluid property model can be favorably integrated in an EHL simulation by an application programming interface (API). The novel hybrid modeling approach is promising for future applications.}}, author = {{Wingertszahn, Patrick and Schmitt, Sebastian and Thielen, Stefan and Oehler, Manuel and Magyar, Balázs and Koch, Oliver and Hasse, Hans and Stephan, Simon}}, issn = {{0724-3472}}, journal = {{Tribologie und Schmierungstechnik}}, keywords = {{Surfaces, Coatings and Films, Surfaces and Interfaces, Mechanical Engineering, Mechanics of Materials}}, number = {{4-5}}, pages = {{5--12}}, publisher = {{Narr Francke Attempto Verlag GmbH + Co.

We derived a set of 36 relevant criteria from the literature and used them to evaluate a total of 46 static analysis tools complying with our inclusion and exclusion criteria - a representative set of mainly non-proprietary tools. The evaluation against the usability criteria in a multiple-raters approach shows that two thirds of the considered tools off er poor warning messages, while about three-quarters provide hardly any fix support. Furthermore, the integration of user knowledge is strongly neglected, which could be used for instance, to improve handling of false positives.

This paper presents a systematic literature review to clarify these terms and introduces FUM, a novel Framework for API Usage constraint and Misuse classification. The literature review revealed that API misuses are violations of API usage constraints. To address this, we provide unified definitions and use them to derive FUM. To assess the extent to which FUM aids in determining and guiding the improvement of an API misuses detector’s capabilities, we performed a case study on the state-of the-art misuse detection tool CogniCrypt.

Relying on a common infrastructure for EM-aware system workload management and test, it minimizes the stress induced by the test itself and contributes to the self-healing of system-induced electromigration degradations. }}, author = {{Sadeghi-Kohan, Somayeh and Hellebrand, Sybille and Wunderlich, Hans-Joachim}}, issn = {{2168-2356}}, journal = {{IEEE Design &Test}}, keywords = {{Electrical and Electronic Engineering, Hardware and Architecture, Software}}, pages = {{1--1}}, publisher = {{Institute of Electrical and Electronics Engineers (IEEE)}}, title = {{{Workload-Aware Periodic Interconnect BIST}}}, doi = {{10.1109/mdat.2023.3298849}}, year = {{2023}}, } @inproceedings{45830, author = {{Jafarzadeh, Hanieh and Klemme, Florian and Reimer, Jan Dennis and Najafi Haghi, Zahra Paria and Amrouch, Hussam and Hellebrand, Sybille and Wunderlich, Hans-Joachim}}, booktitle = {{IEEE International Test Conference (ITC'23), Anaheim, USA, October 2023}}, location = {{Anaheim, USA}}, publisher = {{IEEE}}, title = {{{Robust Pattern Generation for Small Delay Faults under Process Variations}}}, year = {{2023}}, } @inproceedings{52800, author = {{Stüker, Daniel and Schöppner, Volker}}, booktitle = {{INTERNATIONAL CONFERENCE ON HUMANS AND TECHNOLOGY: A HOLISTIC AND SYMBIOTIC APPROACH TO SUSTAINABLE DEVELOPMENT: ICHT 2022}}, issn = {{0094-243X}}, publisher = {{AIP Publishing}}, title = {{{Simplified numerical calculation of the isothermal, three-dimensional, Non-Newtonian flow characteristics of single-screw melt-extruder}}}, doi = {{10.1063/5.0138943}}, year = {{2023}}, } @inbook{45110, author = {{Gräßler, Iris and Steffen, Eckhard and Maier, Günter W. and Roesmann, Daniel}}, booktitle = {{The Digital Twin of Humans}}, editor = {{Gräßler, Iris and Maier, Günter W. and Steffen, Eckhard and Roesmann, Daniel}}, isbn = {{9783031261039}}, pages = {{3--10}}, publisher = {{Springer International Publishing}}, title = {{{Introduction—The Digital Twin of Humans}}}, doi = {{10.1007/978-3-031-26104-6_1}}, year = {{2023}}, } @book{45191, editor = {{Gräßler, Iris and Maier, Günter W. and Steffen, Eckhard and Roesmann, Daniel}}, isbn = {{9783031261039}}, publisher = {{Springer International Publishing}}, title = {{{The Digital Twin of Humans}}}, doi = {{10.1007/978-3-031-26104-6}}, year = {{2023}}, } @inproceedings{31733, author = {{Schöppner, Volker and Brüning, Florian}}, booktitle = {{36th International Conference of the Polymer Processing Society (PPS-36)}}, location = {{Montreal (Kanada)}}, title = {{{Calibration of a Contact Model for DEM Simulations of Grooved Feed Sections of Single Screw Extruders}}}, doi = {{10.1063/5.0135858}}, year = {{2023}}, } @inbook{45187, author = {{Pöhler, Alexander and Gräßler, Iris}}, booktitle = {{The Digital Twin of Humans}}, isbn = {{9783031261039}}, pages = {{171--185}}, publisher = {{Springer International Publishing}}, title = {{{Individual Assembly Guidance}}}, doi = {{10.1007/978-3-031-26104-6_8}}, year = {{2023}}, } @inproceedings{34748, author = {{Vogtschmidt, Sascha and Schöppner, Volker}}, location = {{Tokyo}}, title = {{{The short-and long-term properties of welded high-temperature-resistant thermoplastics}}}, doi = {{10.1007/s40194-023-01595-3}}, year = {{2023}}, } @article{52802, abstract = {{AbstractCurrently, the fused deposition modeling (FDM) process is the most common additive manufacturing technology. The principle of the FDM process is the strand wise deposition of molten thermoplastic polymers, by feeding a filament trough a heated nozzle. Due to the strand and layer wise deposition the cooling of the manufactured component is not uniform. This leads to dimensional deviations which may cause the component to be unusable for the desired application. In this paper, a method is described which is based on the shrinkage compensation through the adaption of every single raster line in components manufactured with the FDM process. The shrinkage compensation is based on a model resulting from a DOE which considers the main influencing factors on the shrinkage behavior of raster lines in the FDM process. An in‐house developed software analyzes the component and locally applies the shrinkage compensation with consideration of the boundary conditions, e.g., the position of the raster line in the component and the process parameters. Following, a validation using a simple geometry is conducted to show the effect of the presented adaptive scaling method.}}, author = {{Moritzer, Elmar and Hecker, Felix}}, issn = {{1022-1360}}, journal = {{Macromolecular Symposia}}, keywords = {{Materials Chemistry, Polymers and Plastics, Organic Chemistry, Condensed Matter Physics}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Adaptive Scaling of Components in the Fused Deposition Modeling Process}}}, doi = {{10.1002/masy.202200181}}, volume = {{411}}, year = {{2023}}, } @inproceedings{52801, author = {{Altepeter, Matthias and Wanke, Sven and Schöppner, Volker}}, booktitle = {{INTERNATIONAL CONFERENCE ON HUMANS AND TECHNOLOGY: A HOLISTIC AND SYMBIOTIC APPROACH TO SUSTAINABLE DEVELOPMENT: ICHT 2022}}, issn = {{0094-243X}}, publisher = {{AIP Publishing}}, title = {{{Analysis and modelling of the material degradation of polypropylene on the co-rotating twin-screw extruder}}}, doi = {{10.1063/5.0135824}}, year = {{2023}}, } @inbook{45111, author = {{Roesmann, Daniel and Gräßler, Iris}}, booktitle = {{The Digital Twin of Humans}}, isbn = {{9783031261039}}, pages = {{187–203}}, publisher = {{Springer International Publishing}}, title = {{{Integration of Human Factors for Assembly Systems of the Future}}}, doi = {{10.1007/978-3-031-26104-6_9}}, year = {{2023}}, } @article{48657, author = {{Moritzer, Elmar and Tölle, Lisa and Greb, C. and Haag, M.}}, issn = {{2504-477X}}, journal = {{Journal of Composites Science}}, number = {{7}}, pages = {{267}}, title = {{{Conceptions and Feasibility Study of Fiber Orientation in the Melt as Part of a Completely Circular Recycling Concept for Fiber-Reinforced Thermoplastics}}}, doi = {{10.3390/jcs7070267}}, year = {{2023}}, } @article{48750, author = {{Schöppner, Volker and Altepeter, Matthias and Austermeier, Laura and Wanke, Sven and Meinheit, Philipp}}, journal = {{Polymers 2023}}, number = {{15(9)}}, pages = {{2181}}, title = {{{Polypropylene Degradation on Co-Rotating Twin-Screw Extruders}}}, doi = {{10.3390/polym15092181}}, year = {{2023}}, } @inproceedings{34736, author = {{Schöppner, Volker and Frank, Maximilian}}, location = {{Fukuoka}}, title = {{{Investigation of the Homogenization Performance of Various Faceted Mixers and Optimization with Regard to Mixing as well as Pressure Throughput Behavior}}}, doi = {{10.1063/5.0135825}}, year = {{2023}}, } @inproceedings{29946, author = {{Schall, Christoph Wilhelm Theodor and Schöppner, Volker}}, booktitle = {{PPS36}}, keywords = {{Computing Resources Provided by the Paderborn Center for Parallel Computing}}, title = {{{Design of a test bench for measuring the degradation behavior of plastics during processing}}}, year = {{2023}}, } @article{48742, author = {{Schöppner, Volker and Schall, Christoph Wilhelm Theodor}}, journal = {{Materials}}, number = {{16(17)}}, pages = {{5891}}, title = {{{Material Characterization of Polypropylene and Polystyrene Regarding Molecular Degradation Behavior}}}, doi = {{10.3390/ma16175891}}, year = {{2023}}, } @article{48654, author = {{Moritzer, Elmar and Held, Christian}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, title = {{{Characterization of additively manufactured parts for direct screwing}}}, doi = {{10.1007/s40194-023-01610-7}}, year = {{2023}}, } @inproceedings{46488, abstract = {{AbstractNew trends and technologies in product creation increase complexity, but at the same time create new potentials such as efficiency rise in task processing by Artificial Intelligence.

In this article, we present a method for dynamical online filtering and uncertainty determination for noisy force curves using two types of Bayesian filters. The methodology is based on a Bayesian probability framework using a priori information for the process curve and sensor noise. To investigate the general feasibility of the method, force measurements with different noise levels are simulated and processed. The conformity is further assessed taking the uncertainty of the filtered signal into account. The results show that the Bayes filter technique is principally able to reduce noise for well-known characteristics of the process curve and sensor noise. Advantages over common filtering techniques, especially for experimental conditions with less known characteristics, are still to be verified. The methodology could be used in future for closed-loop controls to adapt process parameters dynamically. }}, author = {{Butzhammer, Lorenz and Kappe, Fabian and Meschut, Gerson and Hausotte, Tino }}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Dynamic conformity assessment for joining force monitoring using Bayes filters}}}, doi = {{10.21741/9781644902417-48}}, year = {{2023}}, } @inproceedings{46974, author = {{Gräßler, Iris and Hieb, Michael}}, publisher = {{CIRP }}, title = {{{Creating Synthetic Datasets for Deep Learning used in Machine Vision}}}, year = {{2023}}, } @inproceedings{46219, abstract = {{AbstractTo select design guidelines engineers have to identify relevant from a bewildering amount of design guidelines.

Challenging in the manufacture of multi-material systems especially in view of changing supply chains is the variety of materials and geometries that bring conventional joining processes to their limits. Therefore, new processes are required, which can react versatile to process and disturbance variables. A widely used industrial joining process is semi-tubular self-piercing riveting, which is however a rigid process. To increase the versatility, the two newly established processes multi-range self-piercing riveting and tumbling self-piercing riveting are combined and the capabilities for targeted material flow control are united. Therefore, an innovative two-stage process based on the combination is introduced in this paper. The rivet is set with the multi-range self-piercing riveting process with an overlap of the rivet head and then formed by a tumbling process. Further, a specific adaptation of the tumbling strategy is used to investigate the possibility of reducing cracks in the rivet head. Thereby, different tumbling strategies are used and similar geometric joint formations are achieved to compare the results. }}, author = {{Wituschek, Simon and Kappe, Fabian and Meschut, Gerson and Lechner, Michael}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Combination of versatile self-piercing riveting processes}}}, doi = {{10.21741/9781644902417-16}}, year = {{2023}}, } @inbook{52859, author = {{de Camargo e Souza Câmara, Igor and Turhan, Anni-Yasmin}}, booktitle = {{Logics in Artificial Intelligence}}, isbn = {{9783031436185}}, issn = {{0302-9743}}, publisher = {{Springer Nature Switzerland}}, title = {{{Deciding Subsumption in Defeasible $$\mathcal {ELI}_\bot $$ with Typicality Models}}}, doi = {{10.1007/978-3-031-43619-2_36}}, year = {{2023}}, } @article{52861, author = {{Gil, Oliver Fernández and Patrizi, Fabio and Perelli, Giuseppe and Turhan, Anni-Yasmin}}, journal = {{CoRR}}, title = {{{Optimal Alignment of Temporal Knowledge Bases}}}, doi = {{10.48550/ARXIV.2307.15439}}, volume = {{abs/2307.15439}}, year = {{2023}}, } @phdthesis{50449, abstract = {{The importance of fiber-reinforced plastics for lightweight construction applications is steadily increasing due to their outstanding weight-specific property values.

Optimization of manufacturing methods is of great importance to reduce the production cost. In this study, two concepts are proposed that can optimize vacuum assisted light resin transfer molding (VA-LRTM) further, leading to a possibility of fully automatic process. Conventional VA-LRTM methods are used to produce complex fiber-reinforced plastics (FRP) and hybrid components. Traditional molds used to produce components via VA-LRTM are sealed using polymer materials to prevent the leakage of matrix system. The seals undergo tremendous amounts of thermal, chemical, and mechanical loadings. Thus, sealings must be replaced in short intervals. In the current study, a concept where sealing is achieved by accelerating the curing of matrix system itself with the help of heating elements and catalysts resulting in a self-sealing approach is proposed. Another concern is mold surface contamination during component production. To address this, a modified automatic cleaning technique based on ultrasonic cleaning was proposed which can be integrated into the production line with minimum modification.

Using multimodal conversation analysis, the paper investigates a nonverbal, embodied, two-person interaction: two players in a survival game strive to gesturally resolve a misunderstanding regarding an in-game mechanic—however, both of their microphones are turned off for the duration of play. The players’ inability to resort to complex language to resolve this issue results in a dense sequence of back-and-forth activity involving gestures, object manipulation, gaze, and body work. Most crucially, timing and modified repetitions of previously produced actions turn out to be the key to overcome both technical and communicative challenges. The paper analyzes these action sequences, demonstrates how they generate intended outcomes, and proposes a vocabulary to speak about these types of interaction more generally. The findings demonstrate the viability of multimodal analysis of VR interaction, shed light on unique challenges of analyzing interaction in virtual reality, and generate broader methodological insights about the study of nonverbal action.}}, author = {{Klowait, Nils}}, issn = {{2578-1863}}, journal = {{Human Behavior and Emerging Technologies}}, keywords = {{Human-Computer Interaction, General Social Sciences, Social Psychology, Virtual Reality : Multimodality, Nonverbal Interaction, Search Sequence, Gesture, Co-Operative Action, Goodwin, Ethnomethodology}}, pages = {{1--15}}, publisher = {{Hindawi Limited}}, title = {{{On the Multimodal Resolution of a Search Sequence in Virtual Reality}}}, doi = {{10.1155/2023/8417012}}, volume = {{2023}}, year = {{2023}}, } @article{45599, abstract = {{We investigate how people with atypical bodily capabilities interact within virtual reality (VR) and the way they overcome interactional challenges in these emerging social environments.

Our findings are subsequently related to renewed discussions of the relationship between agency and environment, and the co-constructed nature of situated action.
