[{"abstract":[{"lang":"eng","text":"Radial shaft seals are used in a variety of applications, where rotating shafts in steady housings have to be sealed. Typical examples are crankshafts, camshafts, differential gear or hydraulic pumps. In the operating state the elastomeric seal ring and the shaft are separated by a lubrication film of just a few micrometers. Due to shear strain and fluid friction the contact area is subject to a higher temperature than the rest of the seal ring. The stiffness of the elastomeric material is intensely influenced by this temperature and thus contact pressure, friction and wear also strongly depend on the contact temperature. In order to simulate the contact behavior of elastomer seal rings it is essential to use a comprehensive approach which takes into consideration the interaction of temperature, friction and wear. Based on this idea a macroscopic simulation model has been developed at the MEGT. It combines a finite element approach for the simulation of contact pressure at different wear states, a semi-analytical approach for the calculation of contact temperature and an empirical approach for the calculation of friction. In this paper the model setup is presented, as well as simulation and experimental results."}],"doi":"https://doi.org/10.1016/j.wear.2013.12.030","extern":"1","title":"A comprehensive model of wear, friction and contact temperature in radial shaft seals","keyword":["Radial shaft seal ring","Contact temperature","Wear","Friction torque","Finite element simulation"],"user_id":"38077","type":"journal_article","publication":"Wear","issue":"1","volume":311,"page":"71-80","intvolume":"       311","author":[{"first_name":"D.","full_name":"Frölich, D.","last_name":"Frölich"},{"id":"97759","last_name":"Magyar","full_name":"Magyar, Balázs","first_name":"Balázs"},{"full_name":"Sauer, B.","first_name":"B.","last_name":"Sauer"}],"department":[{"_id":"146"}],"citation":{"bibtex":"@article{Frölich_Magyar_Sauer_2014, title={A comprehensive model of wear, friction and contact temperature in radial shaft seals}, volume={311}, DOI={<a href=\"https://doi.org/10.1016/j.wear.2013.12.030\">https://doi.org/10.1016/j.wear.2013.12.030</a>}, number={1}, journal={Wear}, author={Frölich, D. and Magyar, Balázs and Sauer, B.}, year={2014}, pages={71–80} }","mla":"Frölich, D., et al. “A Comprehensive Model of Wear, Friction and Contact Temperature in Radial Shaft Seals.” <i>Wear</i>, vol. 311, no. 1, 2014, pp. 71–80, doi:<a href=\"https://doi.org/10.1016/j.wear.2013.12.030\">https://doi.org/10.1016/j.wear.2013.12.030</a>.","short":"D.

These motors can operate in ``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics, a Coulomb friction model is sufficient in many cases, but numerical simulation requires microscopic time steps. This contribution proposes a much faster simulation technique using one evaluation per period of the excitation signal. The proposed technique produces results very close to those of timestep simulation for ultrasonics inertia motors and allows direct determination of the steady-state velocity of an inertia motor from the motion profile of the driving part. Thus it is a useful simulation technique which can be applied in both analysis and design of inertia motors, especially for parameter studies and optimisation.","lang":"eng"}],"author":[{"first_name":"Matthias","full_name":"Hunstig, Matthias","last_name":"Hunstig"},{"full_name":"Hemsel, Tobias","first_name":"Tobias","last_name":"Hemsel"},{"first_name":"Walter","full_name":"Sextro, Walter","last_name":"Sextro"}],"title":"An efficient simulation technique for high-frequency piezoelectric inertia motors"},{"doi":"10.1016/j.camwa.2012.04.021","title":"Variable preconditioning in complex Hilbert space and its application to the nonlinear Schrödinger equation","user_id":"100441","keyword":["Computational Mathematics","Computational Theory and Mathematics","Modeling and Simulation"],"type":"journal_article","publication":"Computers &amp; Mathematics with Applications","issue":"3","volume":65,"page":"449-459","intvolume":"        65","author":[{"last_name":"Karátson","first_name":"J.","full_name":"Karátson, J."},{"last_name":"Kovács","id":"100441","first_name":"Balázs","full_name":"Kovács, Balázs","orcid":"0000-0001-9872-3474"}],"department":[{"_id":"841"}],"publication_status":"published","citation":{"mla":"Karátson, J., and Balázs Kovács. “Variable Preconditioning in Complex Hilbert Space and Its Application to the Nonlinear Schrödinger Equation.” <i>Computers &#38;amp; Mathematics with Applications</i>, vol. 65, no. 3, Elsevier BV, 2012, pp. 449–59, doi:<a href=\"https://doi.org/10.1016/j.camwa.2012.04.021\">10.1016/j.camwa.2012.04.021</a>.","bibtex":"@article{Karátson_Kovács_2012, title={Variable preconditioning in complex Hilbert space and its application to the nonlinear Schrödinger equation}, volume={65}, DOI={<a href=\"https://doi.org/10.1016/j.camwa.2012.04.021\">10.1016/j.camwa.2012.04.021</a>}, number={3}, journal={Computers &#38;amp; Mathematics with Applications}, publisher={Elsevier BV}, author={Karátson, J. and Kovács, Balázs}, year={2012}, pages={449–459} }","short":"J.

For this process compounding extruders are used which mostly involve tightly intermeshing, co-rotating twin screw extruders. These extruders consist of two closely spaced screws which rotate in the same direction and convey the raw material to the screw tip. These screws are surrounded by several barrel modules which heat or cool the material. As the whole design of the machine is modularly arranged the process behavior of a twin screw extruder depends for the main part on the arrangement of the screw and the barrel elements. Until today this arrangement and process optimization is conducted by experienced engineers and with the help of trial-and-error methods. Furthermore, theoretical models are used with which the behavior of the extruder is estimated. As these models are mostly very complex they are only made available with the realization in different software projects. One of the tools is called SIGMA.

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"}],"user_id":"14931","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":"A.-L.

As research shows, the time it takes to reconfigure the hardware forms an overhead that can significantly impair the benefits of hardware customization. Multi-context devices are one promising approach to overcome the limitations posed by long reconfiguration times. In contrast to more traditional reconfigurable architectures, multi-context devices hold several configurations on-chip. On demand, the device can quickly switch to another context. In this paper we present a co-simulation environment to investigate design trade-offs for hybrid multi-context architectures. Our architectural model comprises a reconfigurable unit closely coupled to a CPU core. As a case study, we discuss the implementation of a FIR filter partitioned into several contexts. We outline the mapping process and present simulation results for single- and multi-context reconfigurable units coupled with both embedded and high-end CPUs."}],"author":[{"first_name":"Rolf","full_name":"Enzler, Rolf","last_name":"Enzler"},{"orcid":"0000-0001-5728-9982","first_name":"Christian","full_name":"Plessl, Christian","last_name":"Plessl","id":"16153"},{"id":"398","last_name":"Platzner","full_name":"Platzner, Marco","first_name":"Marco"}],"title":"Co-simulation of a Hybrid Multi-Context Architecture","department":[{"_id":"518"},{"_id":"78"}],"user_id":"24135","keyword":["Zippy","co-simulation"],"citation":{"bibtex":"@inproceedings{Enzler_Plessl_Platzner_2003, title={Co-simulation of a Hybrid Multi-Context Architecture}, booktitle={Proc.

We consider explicitly declared signals, ports, local variables, and shared variables. Our specification defines an abstract VHDL ’ 93 interpreter in the form of transition rules for an evolving algebra machine (EA-Machine) [60]. It faithfully reflects and supports the view of simulation given in the IEEE VHDL ’ 93 standard language reference manual. The definition can be understood without any prior formal training.
