One single, powerful visualization node is supported by a group of backend nodes with weak graphics performance. While the visualization node renders the visible objects, the backend nodes asynchronously perform visibility tests and supply the front end with visible scene objects. The visualization node stores only currently visible objects in its memory, while the scene is distributed among the backend nodes’ memory without redundancy. To efficiently compute the occlusion tests in spite of that each backend node stores only a fraction of the original geometry, we complete the scene by adding highly simplified versions of the objects stored on other nodes. We test our system with 15 backend nodes. It is able to render a ≈ 350,M polygons (≈ 8.5,GiB) large aircraft model with 20, to 30,fps and thus allows a walk-through in real-time.\r\n"}]},{"title":"Geführte akustische Wellen zur Flüssigkeitscharakterisierung","doi":"10.1524/teme.2012.0176","date_updated":"2022-01-06T06:51:46Z","date_created":"2019-10-16T14:00:53Z","author":[{"full_name":"Rautenberg, Jens","last_name":"Rautenberg","first_name":"Jens"},{"full_name":"Bause, Fabian","last_name":"Bause","first_name":"Fabian"},{"last_name":"Henning","full_name":"Henning, Bernd","id":"213","first_name":"Bernd"}],"year":"2012","citation":{"bibtex":"@article{Rautenberg_Bause_Henning_2012, title={Geführte akustische Wellen zur Flüssigkeitscharakterisierung}, DOI={<a href=\"https://doi.org/10.1524/teme.2012.0176\">10.1524/teme.2012.0176</a>}, journal={tm - Technisches Messen}, author={Rautenberg, Jens and Bause, Fabian and Henning, Bernd}, year={2012}, pages={135–142} }","short":"J.

Das Einsatzgebiet von Polyamiden ist sehr vielseitig. Neben dem massiven Einsatz in der Textilindustrie sei beispielsweise auch der Einsatz in Seilen und Trassen, Zahnrädern und Lagern genannt. Weiterhin findet PA 6 kompositäre Verwendung als Matrixmaterial in thermoplastischen Faserverbundmaterialien (u. a. endlosfaserverstärkte Organobleche) und ist dabei vor allem für die Automobilindustrie von immens steigender Bedeutung. Neben der bei PA ausgeprägten reversiblen Polykondensation, d.h. der Reaktion des Kunststoffes mit Wasser aus der Umgebungsluft, treten irreversible Prozesse (Thermooxidation, Photooxidation, Nachkondensation, $\\ldots$) auf, welche seine chemischen und mechanischen Eigenschaften beeinflussen. In diesem Beitrag sollen die Auswirkungen hydrothermischer Alterung durch Temperatur und Feuchtigkeit, auf die akustischen bzw. mechanischen Eigenschaften zum einen im hochfrequenten (Ultraschall) und zum anderen im quasistatischen Bereich charakterisiert werden. Dazu werden PA 6 Probekörper mittels Klimawechseltests künstlich gealtert und in zwei verschiedenen Versuchsaufbauten beurteilt. Zum einen werden hohlzylindrische Proben zur Charakterisierung im Ultraschallbereich (Schallgeschwindigkeit, Schallkennimpedanz, Schallabsorption) und zum anderen Schulterstäbe zur Charakterisierung der mechanischen Materialeigenschaften im quasistatischen Bereich verwendet. Die akustischen Materialkenngrößen der Ultraschallcharakterisierung und die mechanischen Materialkenngrößen aus dem quasistatischen Bereich, werden abschließend miteinander korreliert und Zusammenhänge dargestellt.","lang":"eng"}],"type":"conference"},{"date_updated":"2022-01-06T06:51:48Z","date_created":"2019-10-24T13:18:35Z","author":[{"full_name":"Bause, Fabian","last_name":"Bause","first_name":"Fabian"},{"first_name":"Jens","last_name":"Rautenberg","full_name":"Rautenberg, Jens"},{"first_name":"Bernd","full_name":"Henning, Bernd","id":"213","last_name":"Henning"}],"title":"Sensitivity study of signal characteristics for an inverse waveguide based approach of material characterization","year":"2012","citation":{"ama":"Bause F, Rautenberg J, Henning B. <i>Sensitivity Study of Signal Characteristics for an Inverse Waveguide Based Approach of Material Characterization</i>.; 2012.","ieee":"F.

Das Schlierenverfahren ist ein schnelles und nichtinvasives Verfahren zur Visualisierung von Ultraschallfeldern in Flüssigkeiten. Bei diesem Verfahren wird eine ebene elektromagnetische Welle an einer Ultraschallwelle gebeugt. Das Beugungsmuster wird durch ein optisches System in der Fourierebene abgebildet. Um die mittlere Helligkeit in der Darstellung der Ultraschallwellen zu eliminieren, erfolgt eine Ortsfilterung in der Fourierebene. Als Ortsfilter werden in der Regel eine Messerschneide oder eine Punktblende eingesetzt. Hierbei wird ein Teil der Fourierebene ausgeblendet und der unbeeinflusste Anteil in Richtung des Bildaufnahmesensors transmittiert. Der Einsatz solcher Amplitudenfilter hat den Nachteil, dass die Phaseninformation einer Schallwelle in der Abbildung der Ultraschallwelle nicht erfasst wird. Der am Fachgebiet Elektrische Messtechnik der Universität Paderborn entwickelte Schlierenmessplatz ist durch ein variables Amplitudenfilter gekennzeichnet. In diesem Beitrag wird ein Verfahren vorgestellt, wie durch Kombination von unterschiedlichen Filtern die Phaseninformation einer Ultraschallwelle rekonstruiert werden kann. Hierzu werden die mathematischen Grundlagen zur Rekonstruktion der Phase hergeleitet und die ersten Messergebnisse vorgestellt.","lang":"eng"}],"type":"conference","language":[{"iso":"eng"}],"department":[{"_id":"49"}],"user_id":"15911","_id":"14001"},{"title":"Ein wellenleiterbasiertes Verfahren zur Bestimmung von Materialdaten für die realitätsnahe Simulation von Schallausbreitungsphänomenen am Beispiel stark absorbierender Kunststoffe","date_updated":"2022-01-06T06:51:49Z","publisher":"Elektrotechnik","author":[{"full_name":"Rautenberg, Jens","last_name":"Rautenberg","first_name":"Jens"}],"date_created":"2019-10-24T13:25:49Z","place":"Paderborn","year":"2012","citation":{"ama":"Rautenberg J. <i>Ein Wellenleiterbasiertes Verfahren Zur Bestimmung von Materialdaten Für Die Realitätsnahe Simulation von Schallausbreitungsphänomenen Am Beispiel Stark Absorbierender Kunststoffe</i>.

Die gezielte Variation der Modell-Eingangsgrößen führt schließlich zu einer bestmöglichen Übereinstimmung zwischen berechneten und gemessenen Empfangssignalen, sodass die final angesetzten Modell-Eingangsgrößen eine gute Approximation der gesuchten materialspezifischen akustischen Kenngrößen darstellen.

To simulate wave propagation in geometrically simple waveguides (plates or rods), one may employ the analytical global matrix method [1]. This requires the computation of all roots of the determinate of a certain submatrix. The evaluation of all real or even complex roots is actually the methods most concerning restriction. Previous approaches base on so called mode-tracers which use the physical phenomenon that solutions (roots) appear in a certain pattern (waveguide modes) and thus use known solutions to limit the root finding algorithms searchspace with respect to consecutive solutions. As the limitation of searchspace might be unstable in some cases, we propose to replace the mode-tracer with a suitable version of an interval Newton method based on Intlab [2]. To apply this interval based method, we extended the interval and derivative computation provided by Intlab such that corresponding information is also available for Bessel functions used in the circular model (rods) of acoustic waveguides. We present numerical results of a simple acoustic waveguide and discuss extensions required for more realistic scenarios.","lang":"eng"}],"status":"public","type":"conference","language":[{"iso":"eng"}],"_id":"14008","department":[{"_id":"49"}],"user_id":"15911"},{"date_updated":"2022-01-06T06:51:49Z","author":[{"first_name":"Mikhail","full_name":"Zubtsoc, Mikhail","last_name":"Zubtsoc"},{"full_name":"Lucklum, Ralf","last_name":"Lucklum","first_name":"Ralf"},{"first_name":"Manzhu","last_name":"Ke","full_name":"Ke, Manzhu"},{"first_name":"Alexandr","last_name":"Oseev","full_name":"Oseev, Alexandr"},{"full_name":"Grundmann, Ralf","last_name":"Grundmann","first_name":"Ralf"},{"last_name":"Henning","full_name":"Henning, Bernd","id":"213","first_name":"Bernd"},{"last_name":"Hempel","full_name":"Hempel, Ulrike","first_name":"Ulrike"}],"date_created":"2019-10-25T12:42:08Z","volume":186,"title":"2D phononic crystal sensor with normal incidence of sound","year":"2012","citation":{"apa":"Zubtsoc, M., Lucklum, R., Ke, M., Oseev, A., Grundmann, R., Henning, B., &#38; Hempel, U.

The characteristic transmission peak has been found to strongly depend on sound velocity of the liquid the plate is immersed in. The respective peak maximum frequency can serve as measure for the concentration of a component in the liquid mixture, if a beneficial relation to the speed of sound of the liquid exists. Experimental verification has been performed with mixtures of water and propanol as model system. Here we especially pay attention to numerical calculations based on EFIT and COMSOL which reveal more insides to the wave propagation characteristics. Experimental investigations with Schlieren method and laser interferometry support the theoretical findings.","lang":"eng"}],"status":"public"}]
