Im Jahr 2024 feiert das Fachgebiet Rehabilitationstechnologie am Fachgebiet Rehabilitationswissenschaften der TU Dortmund sein 20-jähriges Jubiläum. Gleichzeitig verabschiedet sich Prof. Dr.-Ing. Christian Bühler, der 2004 die seinerzeit erste Professur für Rehabilitationstechnologie besetzte, in den Ruhestand. Zwei Jahrzehnte sind vergangen, in denen intensiv an der Umsetzung der Teilhabe für und mit Menschen mit Behinderungen gearbeitet und geforscht wurde. Auf dem Weg begleiteten viele Koo...

To obtain the solution of the viscoelastic fluid simulation with pure polymer melts is a highly challenging task due to the lack of the solvent contribution to the viscosity in the standard viscoelastic formulation. The aim of this paper is to present a mixed finite element method for solving the three field Stokes flow with zero solvent viscosity employing the Elastic Viscous Stress Splitting (EVSS) formulation. On one hand, the EVSS formulation helps to recover the velocity coupling back into t...
Due to the COVID-19 pandemic, schools were closed twice in Germany for several months. The aim of the present study was to investigate whether distant teaching activities increased from the first school lockdown to the second school lockdown and whether the frequency of distant teaching activities were related to students’ outcomes (motivation, competent and independent learning, perceived learning progress) during distant learning. To this end, N = 3,480 legal guardians filled in an online q...
We analyze a system of equations that describes the propagation of sound waves. We are interested in complex constructions along a part of the boundary of the domain, for example constructions with small chambers that are connected to the domain. We also allow that different flow equations are used in the chambers, e.g., modelling a damping material. In addition to the complex geometry, we assume that the viscosity vanishes in the limit. The limiting system is given by wave equations, ...
The use of digital media in education can bring great benefits and its use in schooling is steadily increasing. Administrating paper- versus computer-based as well as fixed-item versus adaptive tests could create differences in test experience, which can threaten the comparability of test results. This study investigated how the pen-and-paper, computer-based, and computer-adaptive test formats of a standardized reading comprehension test affect test anxiety and motivation among German fourth-...
For accelerating Binarized Neural Networks (BNNs), analog computing-based crossbar accelerators, utilizing XNOR gates and additional interface circuits, have been proposed. Such accelerators demand a large amount of analog-to-digital converters (ADCs) and registers, resulting in expensive designs. To increase the inference efficiency, the state of the art divides the interface circuit into an Analog Path (AP), utilizing (cheap) analog comparators, and a Digital Path (DP), utilizing (expensive...
The transformative power of AI raises serious concerns about ethical issues within organizations and implicates the need for trust. To cope with that, numerous ethical frameworks are generally published, but only on a theoretical level. Furthermore, proper trust calibration in AI is of high relevance for the workers. Up to now, only limited studies have been carried out to investigate how an ethical framework can foster proper trust calibration of workers in practice. To close this gap, an et...
A better understanding of how distractor features influence the plausibility of distractors is essential for an efficient multiple-choice (MC) item construction in educational assessment. The plausibility of distractors has a major influence on the psychometric characteristics of MC items. Our analysis utilizes the nominal categories model to investigate German fourth graders' (N = 924) selection of response options in a German MC Vocabulary test. We used principles from cognitive psychology ...
In this work, the monitorability of fatigue damage in notched thermoplastic-based hybrid fiber metal laminate, containing AA6082-T4 sheets and glass and carbon fiber-reinforced polyamide 6, is investigated using constant amplitude tests. Electrical resistance measurement and digital image correlation were combined to determine the initiation and evolution process of fatigue damage. Preliminary to the application of the electrical resistance measurement during fatigue load, basic investigation...
Parents to children with autism spectrum disorder (ASD) experience increased levels of stress compared to other parents. However, it has been difficult to clarify how this parental stress affects the quality of parent partnership, and how stress and partnership quality predict each other longitudinally. Stress and perceived partnership quality of 160 parents to children with ASD who started therapy in an autism therapy center were surveyed at three measurement points. To find out about within...
Trust in the news media is an important prerequisite for democracies. Building on media trust and accuracy research, we investigate reciprocal effects between perceived accuracy and trust in news. We implemented a two-wave online panel survey (N = 952) in the context of the 2021 German federal election. For media individuals' use, we find that trust and accuracy are reciprocally related and are influenced by media use. For the media in general, only trust has an effect on accuracy, whereas me...
Der Fragebogen wurde entwickelt, damit Lehrkräften ihr professionelles Wissen über schulische Medienkompetenzen unter dem Einsatz digitaler Medien und assisstiven Technologien in inklusiven Lerngruppen selbst einschätzen können. Die Zielgruppe des Fragebogens sind Lehramtsstudierende, Lehramtsanwärter:innen, Referen-dar:innen und Lehrkräfte im Bereich der inklusiven Schule. Der Fragebogen knüpft an das Technological, Pedagogical and Content Knowledge Modell (TPACK-Modell) nach Koehler et al. ...
Durch die Elektrifizierung des Verkehrs- und Wärmesektors sowie die Erhöhung der installierten Leistung von Erneuerbare-Energien-Anlagen (EEA) müssen neue flexible Verbraucher und Erzeuger in die elektrischen Verteilnetze integriert werden. Um das Dargebot der EEA zu nutzen und die Erzeugung aus konventionellen Kraftwerken gering zu halten, kann die Flexibilität marktdienlich bewirtschaftet werden und orientiert sich somit am Zustand des gesamten Energiesystems. Dadurch kann situativ eine hoh...
Licht als externer Stimulus zur Regulation der Proteinaktivität hat gegenüber klassischen Inhibitoren und Aktivatoren verschiedene Vorteile, wie z.B. eine sehr hohe räumliche und zeitliche Auflösung. Der Einsatz von photosensitiven Proteinen zur Untersuchung des dynamischen Verhaltens von intrazellulären Reaktionen und Reaktionskaskaden ist daher von großem Interesse. Photoaktive Proteine lassen sich in der Regel in zwei Module unterteilen. Die Sensordomäne, die mit einem lichtempfindlichen L...
Das Ausströmen eines Gases aus einem unter Druck stehenden Behälter gehört zu den klassischen strömungsmechanischen Grundlagenproblemen. Gerade der kompressible und unterkritische Fall ist hierbei komplexer als sich zunächst vermuten lässt und es gibt keine allgemeine analytische Lösung. Dieser Fall soll hier näher untersucht werden. So wird zunächst eine allgemeine selbstähnliche Lösung hergeleitet sowie eine dimensionslose Kennzahl identifiziert, mit der die Ausströmung ohne aufwändige nume...
The sarcomere is the basic unit of striated muscles and consists of interdigitating thick and thin filaments. The two types of filaments slide on each other resulting in the shortening of sarcomere itself thereby generating work. The thin filament comprises filamentous actin (F-actin), troponin (Tn), and tropomyosin (Tm). The thick filament is the force bearing part of the sarcomere and it comprises myosin, titin, and myosin-binding protein C (MyBP-C). The vast majority of ...
The ability of a production plant to be flexible by adjusting the operating conditions to changing demands, prices of the products and the raw materials is crucial to maintain a profitable operation. In this respect, the application of mathematical optimization techniques is unanimously recognized to be successful to improve the decision-making process. Typical examples are production planning, scheduling, real-time optimization and advanced process control. The more information are avai...
