Mit MOBAK-3-4 (Motorische Basiskompetenzen) etabliert sich ein kompetenzorientiertes Testverfahren für Dritt- und Viertklässler. In der vorliegenden Untersuchung mit N = 344 Kindern (167 Mädchen; M = 8,78 Jahre, SD = 0,40) sollen die faktorielle Validität des MOBAK-3-4 Testinstruments sowie Zusammenhänge mit dem Geschlecht, Alter und Gewichtsstatus (Body Mass Index, BMI), der Häufigkeit und Art von außerschulischer Sportaktivität sowie dem fähigkeitsorientierten Hagedorn-Parcours aufgeklärt werden. Die zweifaktorielle Struktur des MOBAK-3-4 konnte mit den Faktoren Sich-Bewegen und Etwas-Bewegen bestätigt werden (CFI = 0,97; RMSEA = 0,033). Zusammenhänge mit den motorischen Basiskompetenzen konnten durch die Integration der Kovariaten Geschlecht, Alter und BMI sowie Häufigkeit und Art von außerschulischer Sportaktivität in die konfirmatorische Faktorenanalyse nachgewiesen werden. Jungen zeigten gegenüber Mädchen im Umgang mit dem Ball (Etwas-Bewegen) bessere Leistungen. Mädchen waren hinsichtlich der Ganzkörperkoordination im Raum (Sich-Bewegen) leicht überlegen. Während die älteren Kinder im Etwas-Bewegen stärker als die jüngeren Kinder waren, zeigten sich im Sich-Bewegen keine altersspezifischen Leistungsunterschiede. Weiterhin stand die Häufigkeit Mannschaftssport in einem engen Zusammenhang mit Etwas-Bewegen sowie die Ausübung von Individualsportarten mit Sich-Bewegen. Zudem zeigten die Ergebnisse des Hagedorn-Parcours auf latenter Ebene mittlere bis starke Zusammenhänge mit den Kompetenzbereichen Sich-Bewegen (β = 0,75, p < 0,001) und Etwas-Bewegen (β = 0,66, p < 0,001)."}],"issue":"1","publication":"German Journal of Exercise and Sport Research","department":[{"_id":"318"}],"type":"journal_article","date_created":"2023-03-03T13:45:12Z","article_type":"original","intvolume":"        50","publication_status":"published","date_updated":"2023-09-19T10:07:26Z","author":[{"id":"58723","full_name":"Strotmeyer, Anne","last_name":"Strotmeyer","first_name":"Anne","orcid":"0000-0002-6830-9245"},{"id":"129","last_name":"Kehne","first_name":"Miriam","full_name":"Kehne, Miriam"},{"last_name":"Herrmann","first_name":"Christian","full_name":"Herrmann, Christian"}],"publication_identifier":{"issn":["2509-3142","2509-3150"]},"title":"Motorische Basiskompetenzen","year":"2019","alternative_title":["Zusammenhänge mit Geschlecht, Alter, Gewichtsstatus, außerschulischer Sportaktivität und Koordinationsleistung"],"doi":"10.1007/s12662-019-00596-z","language":[{"iso":"ger"}]},{"language":[{"iso":"ger"}],"_id":"47013","page":"166","editor":[{"full_name":"Stoll, O.","first_name":"O.","last_name":"Stoll"}],"user_id":"52931","conference":{"name":"50.

To establish an efficient and precise estimate of the RUL of a technical product, different  uncertainties  have  to  be  handled.  To  minimize  the  uncertainties  of  the  RUL  estimation,  a  reliable and accurate prognostic approach as well as a good failure threshold are important. Regarding the failure threshold, most often  an  expert  sets  a  fixed  failure  threshold.  However,  neither  the  a  priori  known  failure  threshold  nor  a  fixedthreshold value are feasible in every application. Especially in the case of varying characteristics of the monitored system, an adaptive failure threshold is of great importance concerning the accuracy of the RUL estimation.  Rubber-metal-elements, which are used in a wide range of applications for vibration and sound isolation, are mon-itored by thermocouples to allow for lifetime predictions. Therefore, the element’s state is described by its temper-ature during its service life. Aiming to establish accurate RUL predictions of a rubber-metal-element, uncertainties due to nonlinear material characteristics and changing operational conditions have to be considered. Consequently, different temperature-based failure threshold definitions are implemented and compared within a particle filtering approach.

Many methods were developed to support a reliability focused design or reliability-by-design approachesto tackle this challenge during design process. In field, data-based methods, i. e. condition monitoring enabled bythe rise of machine learning approaches, are exploited to ensure a reliable operation based on the current conditionof the monitored system. In order to take advantage of existing models of system reliability during design phaseand condition monitoring systems during operation, a method is proposed to combine both approaches in order toset up a digital twin with focus on system reliability. The base model of the digital twin is taken from the systemreliability model from the design phase and is used during operation and therein updated to the current reliabilitybased on the state estimation of the condition monitoring system. The approach is illustrated with a case study of arolling bearing test rig.","lang":"eng"}],"date_created":"2019-09-30T09:16:16Z","type":"conference","department":[{"_id":"151"}],"status":"public","conference":{"end_date":"2019.09.26","location":"Hannover","name":"Proceedings of the European Safety and Reliability Conference (ESREL2019)","start_date":"2019.09.22"},"page":"2340-2347","_id":"13461","user_id":"210","editor":[{"full_name":"Beer, Michael","first_name":"Michael","last_name":"Beer"},{"last_name":"Zio","first_name":"Enrico","full_name":"Zio, Enrico"}],"citation":{"short":"T.

However, the lightweight potential of common materials like steel, aluminum or even fiber-reinforcement plastics (FRP) is limited. In keeping with the motto “the best material for the best application”, a new approach for a top-down material design is introduced. With the aim to develop an application tailored material, the multi-material concept is adapted for the thickness dimension of the component. Within this contribution a new optimization- based design methodology is applied on a stiffness relevant car body part. Starting with benchmark simulations of a reference BIW structure, a critical car body component is determined by an internal energy based method and a subsequent sensitivity analysis. The identified demonstrator component is later subdivided into multiple layers and submitted to a first optimization loop in which the developed methodology varies the material parameters for each single layer. Once an optimum for the through-thickness properties of the part is found, further optimization loops with concrete material pendants and manufacturing restrictions are carried out. The result is a hybrid laminate part consisting of steel and FRP plies. To achieve a further improvement in body characteristics and lightweight, the investigated part is redesigned by the aim of topology optimization. Finally, the tailored hybrid stacks are validated in BIW simulations and compared with the reference. The optimization-based approach allows a weight reduction up to 25 % while maintaining or even improving the BIW properties."}],"publication":"Zukunftstechnologien für den multifunktionalen Leichtbau","citation":{"mla":"Camberg, Alan Adam, et al. “TAILORED STACKED HYBRIDS – AN OPTIMIZATION-BASED APPROACH IN MATERIAL DESIGN FOR FURTHER IMPROVEMENT IN LIGHTWEIGHT CAR BODY STRUCTURES.” <i>Zukunftstechnologien Für Den Multifunktionalen Leichtbau</i>, Springer Berlin Heidelberg, 2019, doi:<a href=\"https://doi.org/10.1007/978-3-662-58206-0_12\">10.1007/978-3-662-58206-0_12</a>.","bibtex":"@inbook{Camberg_Stratmann_Tröster_2019, place={Berlin, Heidelberg}, title={TAILORED STACKED HYBRIDS – AN OPTIMIZATION-BASED APPROACH IN MATERIAL DESIGN FOR FURTHER IMPROVEMENT IN LIGHTWEIGHT CAR BODY STRUCTURES}, DOI={<a href=\"https://doi.org/10.1007/978-3-662-58206-0_12\">10.1007/978-3-662-58206-0_12</a>}, booktitle={Zukunftstechnologien für den multifunktionalen Leichtbau}, publisher={Springer Berlin Heidelberg}, author={Camberg, Alan Adam and Stratmann, Ina and Tröster, Thomas}, year={2019} }","ama":"Camberg AA, Stratmann I, Tröster T.

The introduction of novel concepts in laser operation thus has potential to lead to both new applications and fundamental insights2. Spintronics3, in which both the spin and the charge of the electron are used, has led to the development of spin-lasers, in which charge-carrier spin and photon spin are exploited. Here we show experimentally that the coupling between carrier spin and light polarization in common semiconductor lasers can enable room-temperature modulation frequencies above 200 gigahertz, exceeding by nearly an order of magnitude the best conventional semiconductor lasers. Surprisingly, this ultrafast operation of the resultant spin-laser relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both of which are commonly viewed as detrimental in spintronics3 and conventional lasers4. Our results overcome the key speed limitations of conventional directly modulated lasers and offer a prospect for the next generation of low-energy ultrafast optical communication.","lang":"eng"}],"extern":"1","date_created":"2025-04-25T07:21:34Z","department":[{"_id":"977"}],"type":"journal_article","status":"public","publisher":"Springer Science and Business Media LLC","_id":"59687","page":"212-215","volume":568,"user_id":"15911","citation":{"apa":"Lindemann, M., Xu, G., Pusch, T., Michalzik, R., Hofmann, M.

The high-speed joining process (also called “RIVTAC®” or “Impact”) is an innovative and flexible technology. In this process, a tack having a profiled shank and an ogival shaped tip is pushed into the joining partners with a speed of 20 to 40 m/s without any pre-punching. The plastic and friction work is converted into heat, which causes an abrupt rise of temperature in the joining zone. This improves the flowability of the material which leads to filling the annular grooves existing on the shank of the tack. Simultaneously, a force-fit is created between the sheet metal and the tack. Furthermore, the effects of inertia are used so that the thin-walled structures can be joined without any additional tools (e.g. a die). The joining process causes the deformation of the structure, which must be taken into account with regard to tolerances. The numerical simulation is a powerful tool to predict the deformation and the joinability of a complex structure as well as the mechanical properties of the connection. The paper is about the detailed process- and load-simulation of high-speed joining as well as the required experimental data basis, such as temperature and strain rate dependent flow curves. Furthermore, the friction parameters are very important for the physical consideration of the force-fit connection. Coupled structural-thermal simulations of an axisymmetric 2D-model are performed using explicit and implicit codes.","lang":"eng"}],"publication":"Procedia Manufacturing"}]
