It has been defined in terms of child-directed speech (Motherese), child-directed motion (Motionese), and contingency. In the field of developmental robotics, research often assumes that in human-robot interaction (HRI), robots are treated similar to infants, because their immature cognitive capabilities benefit from this behavior. However, according to our knowledge, it has barely been studied whether this is true and how exactly humans alter their behavior towards a robotic interaction partner. In this paper, we present results concerning the acceptance of a robotic agent in a social learning scenario obtained via comparison to adults and 8-11 months old infants in equal conditions. These results constitute an important empirical basis for making use of tutoring behavior in social robotics. In our study, we performed a detailed multimodal analysis of HRI in a tutoring situation using the example of a robot simulation equipped with a bottom-up saliency-based attention model. Our results reveal significant differences in hand movement velocity, motion pauses, range of motion, and eye gaze suggesting that for example adults decrease their hand movement velocity in an Adult-Child Interaction (ACI), opposed to an Adult-Adult Interaction (AAI) and this decrease is even higher in the Adult-Robot Interaction (ARI). We also found important differences between ACI and ARI in how the behavior is modified over time as the interaction unfolds. These findings indicate the necessity of integrating top-down feedback structures into a bottom-up system for robots to be fully accepted as interaction partners."}],"department":[{"_id":"749"}],"user_id":"14931","_id":"17272","language":[{"iso":"eng"}],"keyword":["robot simulation","hand movement velocity","robotic interaction partner","robotic agent","robot-directed interaction","multimodal analysis","Motionese","Motherese","intelligent tutoring systems","immature cognitive capability","human computer interaction","eye gaze","child-directed speech","child-directed motion","bottom-up system","bottom-up saliency-based attention model","adult-robot interaction","adult-child interaction","adult-adult interaction","human-robot interaction","action learning","social learning scenario","social robotics","software agents","top-down feedback structures","tutoring behavior"]},{"citation":{"short":"V.

The conditional independence assumption, prevalent in hidden Markov model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned on the complete observed feature vector sequence. This is a more informative posterior than one conditioned only on the current observation. The novel decoding is used to obtain a transmission-error robust remote ASR system, where the speech capturing unit is connected to the decoder via an error-prone communication network. We show how the clean speech posterior can be computed for communication links being characterized by either bit errors or packet loss.

As electronic systems design can no longer be seen as an isolated hardware design activity, UML becomes of significant interest as a unification language for systems description combining both HW and SW components. This article provides a comprehensive view of the UML applied to System-on-Chip (SoC) and hardware-related embedded systems design. The modeling concepts in the UML language are first introduced, including major diagrams for the representation of the behavior and the structure of systems. The principles behind application specific UML customizations (UML profiles) are summarized, and several examples relevant for SoC design are given, such as the SysML (System Modeling Language) and the SoC Profile. Thereafter, various approaches associating UML with existing HW/SW design languages are presented. Beyond language aspects, the article addresses the question of UML-based design flows, and shows how UML can be applied concretely to the development of electronic-based systems. The current situation about tool support constitutes the last focus of the article. In particular, we show how UML tools can be combined with well-known simulation environments, such as MATLAB.","lang":"eng"}],"status":"public"},{"type":"journal_article","publication":"IET Computers Digital Techniques","status":"public","user_id":"3118","department":[{"_id":"78"}],"_id":"10646","language":[{"iso":"eng"}],"keyword":["reconfigurable architectures","resource allocation","device reconfiguration time","dynamic hardware reconfiguration","dynamically reconfigurable hardware","light-weight runtime system","merge server distribute load","periodic real-time tasks","runtime system overheads","schedulability analysis","scheduling technique","server-based execution","synthesis tool flow"],"issue":"4","publication_identifier":{"issn":["1751-8601"]},"citation":{"apa":"Danne, K., Mühlenbernd, R., &#38; Platzner, M.
