Neben der Absorption im Fluid treten dabei weitere Effekte (zum Beispiel Beugung oder unvollständige Reflexion) auf, die das akustische Signal schwächen oder anderweitig beeinflussen. Die Entwicklung von Verfahren zur Trennung dieser Effekte von der akustischen Absorption bildet daher einen weiteren Schwerpunkt dieser Arbeit.Abschließend wird die Volumenviskosität aus der gemessenen akustischen Absorption für unterschiedliche Fluide in verschiedenen thermodynamischen Zuständen unter Zuhilfenahme anderer bekannter Fluidkenngrößen bestimmt sowie eine Unsicherheitsbetrachtung durchgeführt.","lang":"ger"},{"lang":"eng","text":"The prerequisite for a complete description of fluid dynamic and acoustic processes is that all properties of the fluid are known.While fluid parameters such as the speed of sound or the shear viscosity are known for many liquids over a wide range of thermodynamic states, only limited measurement data exist for the bulk viscosity.In this thesis, a measurement method for the selective determination of the bulk viscosity of liquids, based on the absorption of ultrasonic waves, is developed and implemented.The focus is on the simulation-driven design of algorithms for processing the measurement signals as well as the analysis and further development of a measurement set-up based on the pulse-echo method.In addition to absorption in the fluid, there are other effects (for example diffraction or incomplete reflection) that weaken or otherwise influence the acoustic signal.Therefore, the development of procedures to separate these effects from acoustic absorption is another focus of this work.The bulk viscosity is determined from the measured acoustic absorption for different fluids in different thermodynamic states.

The role of peripubertal testosterone levels in boys in this context is insufficiently understood and may be modulated by a functional polymorphism of the androgen receptor gene (AR), a variable number of CAG repeats. Moreover, there is preliminary evidence that the relationship between testosterone, CAG repeat length, and the severity of depressive symptoms may differ between subclinical and overt depression, but this has neither been studied in a clinical sample of adolescents with depression nor compared between subclinical and overt depression in an adequately powered study. To investigate the relationship between free testosterone, CAG repeat length of the AR, depression status (subclinical vs. overt), and the severity of depressive symptoms, 118 boys treated as in- or daycare patients at a single psychiatric hospital were studied. Of these, 73 boys had at least mild depressive symptoms according to the Beck Depression Inventory-II (BDI-II > 13). Higher-order moderation analysis in the multiple regression framework revealed a constant relationship between free testosterone and depression severity irrespective of the number of CAG repeats in adolescents with a BDI-II score ≤ 13. In adolescents with a BDI-II score > 13, however, there was a significant negative relationship between free testosterone and BDI-II score in patients with <19 CAG repeats and a significant positive relationship regarding free testosterone and BDI-II score in those with more than 28 CAG repeats, even when considering important covariates. These results suggest that the effects of testosterone on mood in male adolescents with depression depend on the genetic make-up of the AR as well as on depression status. This complex relationship should be considered by future studies addressing mental health issues against an endocrine background and may, moreover, contribute to tailored treatment concepts in psychiatric medicine, especially in adults.","lang":"eng"}],"department":[{"_id":"35"},{"_id":"22"},{"_id":"395"}],"user_id":"89838","_id":"27575","language":[{"iso":"eng"}],"extern":"1"},{"publication":"Nutrients","type":"journal_article","abstract":[{"lang":"eng","text":"(1) Background: Evidence has accumulated that patients with anorexia nervosa (AN) are at higher risk for vitamin D deficiency than healthy controls.

However, distinct B cell maturation stages in peripheral blood in adolescents with AN have not been characterized. Treatment effects and the relationship between clinical and B cell parameters are also not fully understood. Here we investigated the phenotype of circulating B cell subsets and the relationship with body composition in adolescents with AN before (T0, n = 24) and after 6 weeks (T1, n = 20) of treatment. Using multi-parameter flow cytometry, we found increased percentages of antigen-experienced B cells and plasmablasts in patients with AN compared to healthy controls (n = 20). In contrast, percentages of CD1d+CD5+ B cells and transitional B cells with immunoregulatory roles were reduced at T0 and T1. These B cell frequencies correlated positively with fat mass, fat mass index (FMI), free fat mass index, and body mass index standard deviation score. In addition, scavenger-like receptor CD5 expression levels were downregulated on transitional B cells and correlated with fat mass and FMI in AN. Our findings that regulatory B cell subgroups were reduced in AN and their strong relationship with body composition parameters point toward an impact of immunoregulatory B cells in the pathogenesis of AN."}],"status":"public","publication":"Scientific Reports","type":"journal_article","extern":"1","language":[{"iso":"eng"}],"_id":"26632","department":[{"_id":"35"},{"_id":"22"},{"_id":"395"}],"user_id":"89838","year":"2021","citation":{"mla":"Freff, Jana, et al. “Alterations in B Cell Subsets Correlate with Body Composition Parameters in Female Adolescents with Anorexia Nervosa.” Scientific Reports, 2021, doi:10.1038/s41598-020-80693-4.","bibtex":"@article{Freff_Schwarte_Bröker_Bühlmeier_Kraft_Öztürk_Hinney_Arolt_Dannlowski_Romer_et al._2021, title={Alterations in B cell subsets correlate with body composition parameters in female adolescents with anorexia nervosa}, DOI={10.1038/s41598-020-80693-4}, journal={Scientific Reports}, author={Freff, Jana and Schwarte, Kathrin and Bröker, Lisa and Bühlmeier, Judith and Kraft, Isabelle and Öztürk, Dana and Hinney, Anke and Arolt, Volker and Dannlowski, Udo and Romer, Georg and et al.}, year={2021} }","short":"J.

In a production line, the quality of a clinch point is primarily controlled by measurement of dimensions, which are accessible from outside. However, methods such as visual testing and measuring the bottom thickness as well as the outer diameter are not able to deliver any information about the most significant geometrical characteristic of the clinch point, neck thickness and undercut. Furthermore, ex-situ destructive methods such as microsectioning cannot detect elastic deformations and cracks that close after unloading. In order to exceed the current limits, a new non-destructive in-situ testing method for the clinching process is necessary. This work proposes a concept to characterize clinch points in-situ by combining two complementary non-destructive methods, namely, computed tomography (CT) and ultrasonic testing. Firstly, clinch points with different geometrical characteristics are analysed experimentally using ex-situ CT to get a highly spatially resolved 3D-image of the object. In this context, highly X-ray attenuating materials enhancing the visibility of the sheet-sheet interface are investigated. Secondly, the test specimens are modelled using finite element method (FEM) and a transient dynamic analysis (TDA) is conducted to study the effect of the geometrical differences on the deformation energy and to qualify the TDA as a fast in-situ non-destructive method for characterizing clinch points at high temporal resolution.

Here, metal and fibre-reinforced thermoplastics (FRTP) are used within this single step joining process and without the usage of auxiliary parts like screws or rivets. For this purpose, heat is applied to improve the formability of the reinforced thermoplastic. This enables joining of the materials using conventional clinching-tools. Focus of this work is the modelling on mesoscopic scale for the numerical simulation of this process. The FTRP-model takes the material behaviour both of matrix and the fabric reinforced organo-sheet under process temperatures into account. For describing the experimentally observed phenomena such as large deformations, fibre failure and the interactions between matrix and fibres as well as between fibres themselves, the usage of conventional, purely Lagrangian based FEM methods is limited. Therefore, the combination of contact-models with advanced modelling approaches like Arbitrary-Lagrangian-Eulerian (ALE), Coupled-Eulerian-Lagrangian (CEL) and Smooth-ParticleHydrodynamics (SPH) for the numerical simulation of the clinching process are employed. The different approaches are compared with regard to simulation feasibility, robustness and results accuracy. It is shown, that the CEL approach represents the most promising approach to describe the clinching process.

The response of the microstructure is, however, strongly affected by variations in the microstructure geometry. The effect of geometry variations is even stronger in cases when the material exhibits plastic deformations. In this work we study a model of a steel alloy with arbitrary distributed elliptic voids. We model one single unit cell of the material containing one single void. The geometry of the void is not precisely known and is modeled as a variable orientation of an ellipse. Large deformations applied to the unit cell necessitate a finite elasto-plastic material model. Since the geometry variation is parameterized, we can utilize the method recently developed for stochastic problems but also applicable to all types of parametric problems — the isoparametric stochastic local FEM (SL-FEM). It is an ideal tool for problems with only a few parameters but strongly nonlinear dependency of the displacement fields on parameters. Simulations demonstrate a strong effect of parameter variation on the plastic strains and, thus, substantiate the use of the parametric computational homogenization approach.","lang":"eng"}],"volume":20,"author":[{"last_name":"Pivovarov","full_name":"Pivovarov, Dmytro","first_name":"Dmytro"},{"first_name":"Julia","full_name":"Mergheim, Julia","last_name":"Mergheim"},{"first_name":"Kai","full_name":"Willner, Kai","last_name":"Willner"},{"first_name":"Paul","full_name":"Steinmann, Paul","last_name":"Steinmann"}],"date_created":"2022-12-05T20:45:22Z","date_updated":"2023-01-02T11:52:59Z","publisher":"Wiley","doi":"10.1002/pamm.202000071","title":"Parametric FEM for computational homogenization of heterogeneous materials with random voids","issue":"1","publication_identifier":{"issn":["1617-7061","1617-7061"]},"publication_status":"published","intvolume":" 20","citation":{"apa":"Pivovarov, D., Mergheim, J., Willner, K., & Steinmann, P.

Our previous CogniDo GI study found no changes of cognition in the early postprandial phase after consumption of two rice types with medium vs. high dietary GI for lunch (i.e., 45 min after starting lunch). This study investigated whether the dietary GI of lunch has an impact on cognition of schoolchildren in the late postprandial phase, 90 min after lunch.\r\n \r\n Methods\r\n A randomized, 2 × 2 crossover intervention study was conducted at a comprehensive school with 5th and 6th grade students. Participants (n = 212) were randomly assigned to either sequence 1 or 2. In the first period, participants of sequence 1 received a dish with high GI rice (GI: 79), those of sequence 2 with medium GI rice (GI: 64)—in the second period, 1 week later, vice versa. Computer-based cognitive testing was performed 90 min after lunch examining tonic alertness, visual search and task switching, and working memory. Treatment effects and treatment effects adjusted for estimated lunch glycemic load (GL) were analyzed using a linear mixed model.\r\n \r\n Results\r\n The selected cognitive parameters were not affected by the GI of lunch 90 min after lunch, neither after intention-to-treat nor in the per-protocol analysis. Adjustment for GL also did not change results.\r\n \r\n Conclusion\r\n The present study revealed no notable differences after the consumption of two rice types with medium vs. high dietary GI for lunch in children’s cognitive function in the late postprandial phase, 90 min after lunch.\r\n \r\n Clinical trial registration\r\n German Clinical Trials Register (DRKS00013597); date of registration: 16/04/2018, retrospectively registered.\r\n ","lang":"eng"}],"publication":"European Journal of Nutrition"},{"doi":"10.1109/mcs.2021.3062956","title":"Encrypted Control for Networked Systems: An Illustrative Introduction and Current Challenges","author":[{"first_name":"Moritz","full_name":"Schulze Darup, Moritz","last_name":"Schulze Darup"},{"first_name":"Andreea B.","full_name":"Alexandru, Andreea B.","last_name":"Alexandru"},{"first_name":"Daniel E.","full_name":"Quevedo, Daniel E.","last_name":"Quevedo"},{"first_name":"George J.","last_name":"Pappas","full_name":"Pappas, George J."}],"date_created":"2023-01-09T16:33:35Z","volume":41,"date_updated":"2023-01-09T16:43:23Z","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","citation":{"ama":"Schulze Darup M, Alexandru AB, Quevedo DE, Pappas GJ.

This contribution proposes a technique to estimate the position and orientation of the sensor nodes from the recorded speech signals. The method assumes that a node comprises a microphone array with synchronously sampled microphones rather than a single microphone, but does not require the sampling clocks of the nodes to be synchronized. From the observed audio signals, the distances between the acoustic sources and arrays, as well as the directions of arrival, are estimated. They serve as input to a non-linear least squares problem, from which both the sensor nodes’ positions and orientations, as well as the source positions, are alternatingly estimated in an iterative process. Given one set of unknowns, i.e., either the source positions or the sensor nodes’ geometry, the other set of unknowns can be computed in closed-form. The proposed approach is computationally efficient and the first one, which employs both distance and directional information for geometry calibration in a common cost function. Since both distance and direction of arrival measurements suffer from outliers, e.g., caused by strong reflections of the sound waves on the surfaces of the room, we introduce measures to deemphasize or remove unreliable measurements. Additionally, we discuss modifications of our previously proposed deep neural network-based acoustic distance estimator, to account not only for omnidirectional sources but also for directional sources. Simulation results show good positioning accuracy and compare very favorably with alternative approaches from the literature.","lang":"eng"}],"status":"public","publication":"EURASIP Journal on Audio, Speech, and Music Processing","type":"journal_article","language":[{"iso":"eng"}],"_id":"22528","department":[{"_id":"54"}],"user_id":"44006","year":"2021","citation":{"apa":"Gburrek, T., Schmalenstroeer, J., & Haeb-Umbach, R.

However, after decades of simulation-backed research, comparability and reproducibility of simulation studies is still low. In this work, we first survey road traffic simulation parameters (that is, scenarios) employed in recent scientific publications, revealing that many publications still do not adequately describe simulation scenarios to make the results comprehensible. As just one example, over 40% of the simulations using either a Manhattan Grid or Chicago Grid do not provide information about the number of lanes. At the same time, our survey reveals that, even though employed road traffic scenarios are very use case specific, there exist many commonalities. We therefore advocate basing research on use case specific variants of a set of these common standard road traffic scenarios. We accompany this recommendation with Simple Synthetic Scenarios for Sumo (SSS4S), a simple reference implementation to generate such variants."}],"publication":"13th IEEE Vehicular Networking Conference (VNC 2021)","type":"conference","language":[{"iso":"eng"}],"user_id":"35441","_id":"28095","citation":{"chicago":"Hardes, Tobias, Dalisha Logan, Christoph Sommer, and Florian Klingler. “Poster: Enabling Comparable and Reproducible Simulations for V2X Research.” In 13th IEEE Vehicular Networking Conference (VNC 2021).

Conventional distillation columns, mostly equipped with structured packings, lack the flexibility to handle product changeovers and throughput. Thus, a newly designed distillation column for specialty chemicals is presented. A numerical model was implemented to analyze the potential of the wetted‐wall column. The simulation of the distillation of a binary methanol/water mixture demonstrated that the wetted‐wall column can generate the desired concentration and temperature profiles. Furthermore, analyses of the pressure drop and separation efficiency with the test system chlorobenzene/ethylbenzene were conducted.","lang":"eng"}],"user_id":"101499","_id":"47569","language":[{"iso":"eng"}],"extern":"1","keyword":["Industrial and Manufacturing Engineering","General Chemical Engineering","General Chemistry"],"issue":"7","publication_identifier":{"issn":["0930-7516","1521-4125"]},"quality_controlled":"1","publication_status":"published","intvolume":" 44","page":"1327-1335","citation":{"bibtex":"@article{Reitze_Grünewald_Riese_2021, title={Concept of a Flexible Wetted‐Wall Column for the Distillation of Specialty Chemicals}, volume={44}, DOI={10.1002/ceat.202000468}, number={7}, journal={Chemical Engineering & Technology}, publisher={Wiley}, author={Reitze, Arnulf and Grünewald, Marcus and Riese, Julia}, year={2021}, pages={1327–1335} }","short":"A.
