    Degradable magnesium alloys are new materials for implants used in orthopedic and trauma surgery. The aim of this study was to investigate the influence of degradable magnesium alloys on the function of dendritic cells ...
  • Tönshoff, H.K.; Kaestner, W. (London : SAGE Publications Ltd., 1991)
    An important component of the total production costs of forged parts are the costs for finish turning. During the last few years near-net - shape technology has been advanced, so that the realizable accuracy by chipless ...
  • Held, Marcel Philipp; Lachmayer, Roland (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    High-resolution vehicle headlamps represent a future-oriented technology that can be used to increase traffic safety and driving comfort. As a further development to the current Matrix Beam headlamps, LED-based pixel light ...
  • Röhlig, Klaus-Jürgen; Häfner, Daniel; Lux, Karl-Heinz; Hassel, Thomas; Stahlmann, Joachim (München : Oekom - Gesellschaft fuer Oekologische Kommunikation mbH, 2017)
    Sollte die Lagerung radioaktiver Abfälle in tiefen geologischen Formationen rückholbar gestaltet werden? Im Artikel werden Optionen zur Gestaltung einer Einlagerung beschrieben, Argumente für und gegen eine Rückholbarkeit ...
  • Campello, Eduardo Moraes Barreto; De Mattos Pimenta, Paulo; Wriggers, Peter (Ouro Preto : REM, 2007)
    The geometrically-exact finite-strain variable-thickness shell model of [1] is reviewed in this paper and extended to the case of metallic elastoplastic shells. Isotropic elasticity and von Mises yield criterion with ...
  • Kauth, Felix; Seume, Joerg R.; Mertens, Axel; Narjes, Gerrit; Ponick, Bernd; Müller, Jan-Kaspar (Zug : Global Power and Propulsion Society, 2018)
    This paper gives an overview of the interdisciplinary design process of an electrically-powered high-lift system for future commercial aircraft, with a focus on the mixed-flow compressor performance. Based on the requirements ...
  • Denkena, Berend; Dahlmann, Dominik; Krueger, R. (Amsterdam : Elsevier, 2015)
    Today's machine tools for ultra-precision machining are generally characterised by low productivity. Above all, practical cutting parameters are limited due to uncontrollable disturbance forces. Therefore, it is necessary ...
  • Blackburn, Jennifer (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2016-10-04)
    This report investigates adaptations of electronic packaging methods used to create stacks of these sensors. Four methods were developed and tested to determine the best option in terms of mechanical stability and electrical ...
  • Denkena, Berend; Köhler, Jens; Breidenstein, Bernd; Mörke, Tobias (Amsterdam : Elsevier BV, 2011)
    In order to qualify residual stress relaxation as an indicator of mechanical overloading of machined parts, an individually designed residual stress profile has to be allocated. Even though numerous investigations have ...
  • Görke, Matthias; Bellmann, Vivian; Busch, Jan; Nyhuis, Peter (Amsterdam : Elsevier BV, 2017)
    Global competition and individual customer requirements generate challenges for manufacturing companies. To cope with these challenges, companies require an increased level of flexibility. In the first place, this flexibility ...
  • Denkena, Berend; Lepper, Thomas (Amsterdam : Elsevier, 2015)
    This paper focuses on a cost-effective manufacturing of large frame parts for aerospace industries with an industrial robot. The main challenge is the low stiffness of a serial kinematic, resulting in positioning errors ...
  • Breidenstein, B.; Denkena, Berend; Grove, T.; Hockauf, R. (Amsterdam : Elsevier, 2016)
    The machining process affects quality and function of components. For this reason, it is an important key competence of the manufacturer. Over the past years, counterfeit products have been threatening the user and damaged ...
  • Gryshkov, Oleksandr; Pogozhykh, Denys; Hofmann, Nicola; Pogozhykh, Olena; Müller, Thomas; Glasmacher, Birgit (San Francisco : Public Library of Science, 2014-09-26)
    Alginate cell-based therapy requires further development focused on clinical application. To assess engraftment, risk of mutations and therapeutic benefit studies should be performed in an appropriate non-human primate ...
  • Kundrat, Dennis; Fuchs, Alexander; Schoob, Andreas; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The introduction of Er:YAG lasers for soft and hard tissue ablation has proven promising results over the last decades due to strong absorption at 2.94 μm wavelength by water molecules. An extension to endoluminal applications ...
  • Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Sheet-bulk metal forming is a new production process capable of performing deep-drawing and massive forming steps in a single operation. However, due to the high forming forces of the forming process, continuous process ...
  • Eggers, Kai Benjamin (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Beim Erwerb eines Industrieroboters werden heutzutage nicht mehr nur klassische Faktoren wie die minimal erreichbare Taktzeit und die Anschaffungskosten als Kaufkriterien betrachtet, sondern auch der Leistungs- und ...
  • Rehe, M.; Denkena, Berend; Wagener, C. (Amsterdam : Elsevier B.V., 2018)
