Hier breitet sich die Schwingungsenergie in Form stehender und fortschreitender Wellen zum akustischen Verbraucher hin aus. Es folgt eine gleichwertige und schaltungstreue Darstellung durch elektrische oder mechanische Vierpole, die für den Entwicklungsingenieur leichter zu handhaben sind und in Netzwerken direkt mit Masons Ersatzschaltung des piezoelektrischen Wandlers gekoppelt werden können. Danach werden die wichtigsten, messtechnisch zugänglichen Parameter anhand eines in Resonanznähe zulässigen Ersatzmodells mit konzentrierten elektrischen bzw. mechanischen Komponenten definiert. Als Schwerpunkt wird anschließend deren analytische Berechnung und messtechnische Verifizierung an typischen Beispielen demonstriert. Es folgen wichtige technische Informationen über Frequenzkorrekturen, Schallgeschwindigkeitsdispersion, Leistungs- und Belastbarkeitsgrenzen der Komponenten und andere wertvolle praktische Hinweise.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Veröffentlichung der Universität Paderborn","title":"Zur Theorie der piezoelektrischen Ultraschallverbundschwinger mit praktischen Schlussfolgerungen für den Entwicklungsingenieur","date_updated":"2022-01-06T07:04:19Z","author":[{"full_name":"Lierke, Ernst-Günter","last_name":"Lierke","first_name":"Ernst-Günter"},{"first_name":"Walter","last_name":"Littmann","full_name":"Littmann, Walter"},{"first_name":"Tobias","full_name":"Hemsel, Tobias","id":"210","last_name":"Hemsel"}],"date_created":"2019-05-13T10:14:21Z","year":"2010","citation":{"apa":"Lierke, E.-G., Littmann, W., &#38; Hemsel, T.

This paper presents a guideline for the dependability-oriented design of self-optimizing systems, which integrates established classical methods like failure mode and effects analysis as well as methods based on self-optimization. On the one hand self-optimization is used to increase the dependability of the system by integrating objectives like safety, availability, and reliability to the objectives of the system. On the other hand methods are required to ensure the self-optimization itself. As basis for this guideline serves the principle solution of the system. The six phases of the guideline extend the design process and lead to an enhanced principle solution.

Self-optimizing systems are complex and due to their non-deterministic behavior comprise hidden risks, which cannot be foreseen in the design phase of the system. Therefore, modifications of the ISO 17359 condition monitoring policy for being able to cope with this new kind of systems are presented. Besides avoiding critical situations evoked by self-optimization, the proposed concept uses self-optimization to increase the dependability of the system. This concept is applied to the active guidance module of an innovative rail-bound vehicle. First test drives provide information for the enhancement of the implementation of realtime switching to appropriate control strategies. The different control strategies are investigated in detail. It is illustrated that influences on the system like different track sections or the desired velocity of the RailCab effect the system and can lead to a higher amount of flange contacts, which indicate higher wear and thus a reduction of the availability of the system. Therefore, these influences should be minded within the condition monitoring policy. Consequently, this article presents the condition monitoring policy for self-optimizing function modules and its application to the active railway guidance module.","lang":"eng"}],"type":"journal_article","publication":"International Journal On Advances in Intelligent Systems"},{"status":"public","editor":[{"first_name":"Jürgen","last_name":"Gausemeier","full_name":"Gausemeier, Jürgen"},{"first_name":"Frans Josef","last_name":"Rammig","full_name":"Rammig, Frans Josef"},{"first_name":"Ansgar","last_name":"Trächtler","full_name":"Trächtler, Ansgar"}],"type":"conference","series_title":"HNI-Verlagsschriftenreihe","user_id":"55222","department":[{"_id":"151"}],"_id":"9762","citation":{"apa":"Sondermann-Wölke, C., Sextro, W., Geisler, J., &#38; Trächtler, A.

In diesem Beitrag wird das selbstoptimierende Spurführungsmodul näher untersucht. Das Spurführungsmodul ist Bestandteil eines innovativen schienengebundenen Verkehrssystems, genannt RailCab, und dient zur Lenkung des einzelnen Fahrzeugs. Ziele des Spurführungsmoduls bestehen darin, die Verlässlichkeit des Spurführungsmoduls zu erhöhen sowie möglichst wenig Energie zu verbrauchen. Um kritische Systemzustände zu erkennen bzw. frühzeitig zu verhindern wird eine Vorgehensweise zur Einrichtung einer Zustandsüberwachung für selbstoptimierende Systeme beschrieben. Diese wird auf dem realen Versuchsträger im Maßstab 1:2,5 implementiert.

In contrary, self-optimization could be used to increase the dependability by pursuing objectives like reliability and availability. In our preceding publications we introduced the so called multi-level dependability concept to cope with this new kind of systems (cf. [6]). This concept comprises the monitoring of the system behavior, the classification of the current situation, and the selection of the appropriate measure, if reliability limits are exceeded. In this paper we present for the first time experimental results. The dependability concept is implemented in the self-optimizing active guidance system of a railway vehicle.

The influence of several experimental parameters, including the plasma induced temperature rise, are analysed using scanning and transmission electron microscopy.

Using a special wedge-type deposition technique, series of 20–35\r\nsamples could be fabricated by magnetron sputtering during one run. The layer thickness of only a few\r\nnanometers, the composition of the alloy, and the quality of interfaces were controlled by Rutherford backscattering\r\nspectrometry, high-resolution transmission electron microscopy, and Auger spectroscopy. The magnetic\r\nproperties of the ferromagnetic alloy layer were characterized with superconducting quantum interference\r\ndevice magnetometry. These studies yield precise information about the thickness and demonstrate the homogeneity\r\nof the alloy composition and magnetic properties along the sample series. The dependencies of the\r\ncritical temperature on the Nb and Cu41Ni59 layer thickness, T_c(d_S) and T_c(d_F), were investigated for constant\r\nthickness d_F of the magnetic alloy layer and d_S of the superconducting layer, respectively. All types of\r\nnonmonotonic behaviors of T_c versus d_F predicted by the theory could be realized experimentally, from\r\nreentrant superconducting behavior with a broad extinction region to a slight suppression of superconductivity\r\nwith a shallow minimum. Even a double extinction of superconductivity was observed, giving evidence for the\r\nmultiple reentrant behavior predicted by theory. All critical temperature curves were fitted with suitable sets of\r\nparameters. Then, T_c(d_F) diagrams of a hypothetical ferromagnet/superconductor/ferromagnet spin-switch core\r\nstructure were calculated using these parameters. Finally, superconducting spin-switch fabrication issues are\r\ndiscussed in detail in view of the achieved results.","lang":"eng"}],"file":[{"file_id":"4201","access_level":"closed","file_name":"Reentrant superconductivity in superconductor-ferromagnetic-alloy bilayers.pdf","file_size":723266,"creator":"hclaudia","date_created":"2018-08-28T12:23:29Z","date_updated":"2018-08-28T12:23:29Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"ddc":["530"],"language":[{"iso":"eng"}]},{"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":688753,"access_level":"closed","file_id":"4203","file_name":"Characterization of unintentional doping in nonpolar GaN.pdf","date_updated":"2018-08-28T12:28:22Z","date_created":"2018-08-28T12:28:22Z","creator":"hclaudia"}],"abstract":[{"text":"Unintentional doping in nonpolar a-plane \u0001112¯0\u0002 gallium nitride \u0001GaN\u0002 grown on r-plane \u000111¯02\u0002\r\nsapphire using a three-dimensional \u00013D\u0002–two-dimensional \u00012D\u0002 growth method has been\r\ncharacterized. For both 2D only and 3D–2D growth, the presence of an unintentionally doped region\r\nadjacent to the GaN/sapphire interface is observed by scanning capacitance microscopy \u0001SCM\u0002. The\r\naverage width of this unintentionally doped layer is found to increase with increasing 3D growth\r\ntime. By using an intentionally doped GaN:Si staircase structure for calibration, it is shown that the\r\nunintentionally doped region has an average carrier concentration of \u00012.5\u00010.3\u0002\u00021018 cm−3. SCM\r\nalso reveals the presence of unintentionally doped features extending at 60° from the GaN/sapphire\r\ninterface. The observation of decreasing carrier concentration with distance from the GaN/sapphire\r\ninterface along these features may suggest that the unintentional doping arises from oxygen\r\ndiffusion from the sapphire substrate. Low temperature cathodoluminescence spectra reveal\r\nemission peaks at 3.41 and 3.30 eV, which are believed to originate from basal plane stacking faults\r\n\u0001BSFs\u0002 and prismatic stacking faults \u0001PSFs\u0002, respectively. It is shown that the inclined features\r\nextending from the GaN/sapphire interface exhibit both enhanced BSF and PSF emission. We\r\nsuggest that enhanced unintentional doping occurs in regions around PSFs. Where BSFs intersect\r\nthis doped material their emission is also enhanced due to reduced nonradiative recombination.\r\nTransmission electron microscopy confirms the presence of PSFs extending through the film at 60°\r\nfrom the GaN/sapphire interface.","lang":"eng"}],"publication":"Journal of Applied Physics","language":[{"iso":"eng"}],"ddc":["530"],"year":"2010","issue":"2","title":"Characterization of unintentional doping in nonpolar GaN","date_created":"2018-08-28T12:27:34Z","publisher":"AIP Publishing","status":"public","type":"journal_article","extern":"1","file_date_updated":"2018-08-28T12:28:22Z","article_type":"original","article_number":"023503","user_id":"55706","department":[{"_id":"15"}],"_id":"4202","citation":{"ama":"Zhu T, Johnston CF, Häberlen M, Kappers MJ, Oliver RA.
