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.}}, author = {{Vanderperren, Yves and Müller, Wolfgang and Dahaene, Wim}}, journal = {{Design Automation for Embedded Systems}}, keywords = {{UML SysML Model-based design System specification Modelling languages}}, pages = {{261--292}}, publisher = {{Springer-Verlag}}, title = {{{UML for Electronic Systems Design – A Comprehensive Overview}}}, doi = {{10.1007/s10617-008-9028-9}}, volume = {{12}}, year = {{2008}}, } @inproceedings{29474, author = {{Zhang, W. and Inanc, T. and Ober-Blöbaum, Sina and Marsden, J.E.}}, booktitle = {{IEEE International Conference on Robotics and Automation}}, location = {{Pasadena, CA, USA}}, title = {{{Optimal trajectory generation for a dynamic glider in ocean flows modeled by 3d B-spline functions}}}, year = {{2008}}, } @article{36070, author = {{Schlegel-Matthies, Kirsten}}, issn = {{0342-5088}}, journal = {{Haushalt & Bildung}}, number = {{2}}, pages = {{3--5}}, publisher = {{Schneider-Verlag}}, title = {{{Konsumentinnen und Konsumenten - politisch denkende und moralisch handelnde Akteure}}}, volume = {{85}}, year = {{2008}}, } @inproceedings{24043, author = {{Pottebaum, Jens and Konstantopoulos, Stasinos and Koch, Rainer and Paliouras, Georgios}}, booktitle = {{Mobile Response, First International Workshop on Mobile Information Technology for Emergency Response, Mobile Response 2007, Sankt Augustin, Germany, February 22-23, 2007, Revised Selected Papers}}, editor = {{Löffler, Jobst and Klann, Markus}}, isbn = {{978-3-540-75667-5}}, keywords = {{Ver{\}}, pages = {{61--70}}, publisher = {{Springer}}, title = {{{SaR Resource Management Based on Description Logics Technology for Emergency Response}}}, doi = {{10.1007/978-3-540-75668-2_7}}, year = {{2008}}, } @article{54950, abstract = {{The mechanisms by which proteases activate the epithelial sodium channel (ENaC) are not yet fully understood. We investigated the effect of extracellular proteases on rat ENaC heterologously expressed in Xenopus laevis oocytes. Application of trypsin increased ENaC whole-oocyte currents by about 8-fold without a concomitant increase in channel surface expression. The stimulatory effect of trypsin was preserved in oocytes expressing alphagamma-ENaC, but was abolished in oocytes expressing alphabeta-ENaC. Thus, the gamma-subunit appears to be essential for channel activation by extracellular proteases. Site-directed mutagenesis of a putative prostasin cleavage site in the extracellular loop of the gamma-subunit revealed that mutating the 181Lys residue to alanine (gammaK181A) increases ENaC baseline whole-oocyte currents, decreases channel surface expression, and largely reduces the stimulatory effect of extracellular proteases (trypsin, chymotrypsin and human neutrophil elastase). In single-channel recordings from outside-out patches we demonstrated that the gammaK181A mutation essentially abolishes the activation of near-silent channels by trypsin, while a stimulatory effect of trypsin on channel gating is preserved. This apparent dual effect of trypsin on channel gating and on the recruitment of near-silent channels was confirmed by experiments using the beta518C mutant ENaC which can be converted to a channel with an open probability of nearly one by exposure to a sulfhydryl reagent. Interestingly, the gammaK181A mutation results in the spontaneous appearance of a 67 kDa fragment of the gamma-subunit in the plasma membrane which can be prevented by a furin inhibitor and also occurs after channel activation by extracellular trypsin. This suggests that the mutation promotes channel cleavage and activation by endogenous proteases. This would lower the pool of near-silent channels and explain the constitutive activation and reduced responsiveness of the mutant channel to extracellular proteases. We conclude that the mutated site (K181A) affects a region in the gamma-subunit of ENaC that is functionally important for the activation of near-silent channels by extracellular proteases.}}, author = {{Diakov, Alexei and Bera, Katarzyna and Mokrushina, Marianna and Krueger, Bettina and Korbmacher, Christoph}}, journal = {{The Journal of Physiology}}, number = {{19}}, pages = {{4587–4608}}, publisher = {{Wiley}}, title = {{{Cleavage in the γ-subunit of the epithelial sodium channel (ENaC) plays an important role in the proteolytic activation of near-silent channels}}}, doi = {{10.1113/jphysiol.2008.154435}}, volume = {{586}}, year = {{2008}}, } @inproceedings{37075, abstract = {{Complex control oriented embedded systems with hard real-time constraints require real-time operation system (RTOS) for predictable timing behavior.

Inspired by human parent-infant interaction, we hypothesize that a robot equipped with infant-like abilities can take advantage of parental proper teaching. Parents are known to significantly alter their infant-directed actions versus adult-directed ones, e.g. make more pauses between movements, which is assumed to aid the infants’ understanding of the actions. As a first step, we analyzed parental actions using a primal attention model. The model based on visual saliency can detect likely important locations in a scene without employing any knowledge about the actions or the environment. Our statistical analysis revealed that the model was able to extract meaningful structures of the actions, e.g. the initial and final state of the actions and the significant state changes in them, which were highlighted by parental action modifications. We further discuss the issue of designing an infant-like robot that can induce parent-like teaching, and present a human-robot interaction experiment evaluating our robot simulation equipped with the saliency model.}}, author = {{Nagai, Yukie and Muhl, Claudia and Rohlfing, Katharina}}, booktitle = {{The 2008 IEEE International Conference on Robotics and Automation}}, keywords = {{icra08}}, pages = {{3545--3550}}, title = {{{Toward Designing a Robot that Learns Actions from Parental Demonstrations}}}, doi = {{10.1109/robot.2008.4543753}}, year = {{2008}}, } @article{64041, abstract = {{Three cis-dioxovanadium(V) complexes with similar N -salicylidenehydrazide ligands modeling hydrogen bonding interactions of vanadate relevant for vanadium haloperoxidases are studied by 51V solid-state NMR spectroscopy.
