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.","lang":"eng"}],"author":[{"first_name":"Anna-Lisa","full_name":"Vollmer, Anna-Lisa","last_name":"Vollmer"},{"last_name":"Lohan","first_name":"Katrin Solveig","full_name":"Lohan, Katrin Solveig"},{"first_name":"Kerstin","full_name":"Fischer, Kerstin","last_name":"Fischer"},{"full_name":"Nagai, Yukie","first_name":"Yukie","last_name":"Nagai"},{"last_name":"Pitsch","full_name":"Pitsch, Karola","first_name":"Karola"},{"first_name":"Jannik","full_name":"Fritsch, Jannik","last_name":"Fritsch"},{"last_name":"Rohlfing","id":"50352","full_name":"Rohlfing, Katharina","first_name":"Katharina"},{"last_name":"Wrede","first_name":"Britta","full_name":"Wrede, Britta"}],"title":"People modify their tutoring behavior in robot-directed interaction for action learning","date_updated":"2023-02-01T13:06:43Z","page":"1-6","_id":"17272","status":"public","language":[{"iso":"eng"}],"year":"2009","type":"conference","publisher":"IEEE","date_created":"2020-06-24T13:02:43Z","publication":"Development and Learning, 2009.

The measurement setup consists of a capacitor, an impedance converter and a voltmeter. Based on the piezoelectric equation and the basic circuit theory, the mathematical expression between the pre-stress and the voltage across the capacitor is derived. The pre-stress level can then be calculated out of the measurement of the capacitor voltage. In order to evaluate the precision of this method, a force washer is used to measure the pre-stress of the Langevin transducer. The result shows the pre-stress level obtained from this method is 30-40\\% higher than the pre-stress level measured by the force washer. This method is simple and can be used to estimate the pre-stress of various Langevin transducers. The precision of this method can be raised if d33 is identified under different pre-stress levels.","lang":"eng"}],"doi":"10.1109/SPAWDA.2008.4775801","author":[{"full_name":"Bo, Fu","first_name":"Fu","last_name":"Bo"},{"full_name":"Ting, Li","first_name":"Li","last_name":"Ting"},{"id":"210","last_name":"Hemsel","full_name":"Hemsel, Tobias","first_name":"Tobias"}],"title":"A simple pre-stress estimating method of langevin transducers"},{"intvolume":"         4","author":[{"last_name":"Rösler","id":"37390","full_name":"Rösler, Margit","first_name":"Margit"},{"first_name":"Michael","full_name":"Voit, Michael","last_name":"Voit"}],"department":[{"_id":"555"}],"citation":{"short":"M.

Even worse, the impacts of these messages are far from being simply an annoyance, as they also involve economic damage. This manuscript examines the resource ?email addresses?, which is vital for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization for implementing an empirical analysis of the usage of email addresses placed on the Internet are proposed here. Their objective is to assess, on a quantitative basis, the extent of the current harassment and its development over time. This ?framework? is intended to be extensible to measuring the effectiveness of address-obscuring techniques. The implementation of a pilot honeypot is described, which led to key findings, some of them being: (1) Web placements attract more than two-thirds (70\\%) of all honeypot spam emails, followed by newsgroup placements (28.6\\%) and newsletter subscriptions (1.4\\%), (2) the proportions of spam relating to the email addresses? top-level domain can be statistically assumed to be uniformly distributed, (3) More than 43\\% of addresses on the web have been abused, whereas about 27\\% was the case for addresses on newsgroups and only about 4\\% was the case for addresses used for a newsletter subscription, (4) Regarding the development of email addresses? attractiveness for spammers over time, the service ?web sites? features a negative linear relationship, whereas the service ?Usenet? hows a negative exponential relationship. (5) Only 1.54\\% of the spam emails showed an interrelation between the topic of the spam email and that of the location where the recipient?s address was placed, so that spammers are assumed to send their emails in a ?context insensitive? manner. The results of the empirical analysis motivate the need for the protection of email addresses through obscuration. We analyze this need by formulating requirements for address obscuring techniques and we reveal to which extent today?s most relevant approaches fulfill these requirements.","lang":"eng"}],"keyword":["Address-obfuscating techniques","email","empirical analysis","honeypot","security by design","security by obscurity","spam"],"oa":"1","user_id":"61579","publication":"Computers & Security","ddc":["000"],"type":"journal_article","volume":2,"page":"361-372","issue":"5"},{"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"],"user_id":"3118","citation":{"apa":"Danne, K., Mühlenbernd, R., &#38; Platzner, M.

The main results were (1) that a masked prime reduced the latency of the mask's conscious perception (perceptual latency priming), (2) that this effect was independent of whether the prime suffered strong or weak masking, (3) that it was unaffected by the degree of visual similarity between the prime and the mask, and that (4) there was no difference between congruent and incongruent primes. Finding (1) suggests that location cueing affects not only response times but also the latency of conscious perception. (2) The finding that priming was unaffected by the prime's detectability argues against a response bias interpretation of this effect. (3) Since visual similarity had no effect on the prime's efficiency, it is unlikely that sensory priming was involved.
