  • Denkena, Berend; Dittrich, Marc-André; Georgiadis, Alexander (Amsterdam : Elsevier BV, 2017)
    The condition of complex products in the transport industry, such as train couplings or aircraft turbines, is not exactly determinable before their disassembly and diagnosis in a maintenance plant. Thus, planning and control ...
  • Weide-Zaage, Kirsten; Payá-Vayá, Guillermo (Walnut, CA : ASTES Publishers, 2017)
    Radiation hardened devices are mostly extremely expensive. The continuously downscaling of microelectronic structures and the unavoidable presence of particle radiation on ground and in space leads to unwanted failures in ...
  • Prehm, J.; Xin, L.; Möhwald, Kai; Bach, Friedrich-Wilhelm (Kuala Lumpur : The International Society for Science & Religion, 2011)
    This paper deals with the simulation of coating formation in Thermal Spray processes. That means that impingement and flattening of molten metal- or ceramic particles with a diameter of about 50 microns on a rough surface ...
  • Südekum, Sebastian; Mantzke, Andreas; Leone, Marco (Aachen : Apprimus, 2016)
    Das Hochfrequenzverhalten elektrischer Leitungen unter dem Einfluss eines äußeren elektromagnetischen Feldes ist ein wichtiger Teil der EMV-Analyse, da die Signalund Versorgungsintegrität elektrischer Systeme stark durch ...
  • Hansen, Jan (Aachen : Apprimus, 2016)
    Dieser Beitrag gibt einen Überblick über die Einsatzmöglichkeiten und Vorgehensweisen der Simulation in der Leistungselektronik, speziell für Hochvoltsysteme. Der Beitrag richtet sich nicht an Spezialisten der EMV Simulation ...
  • Wolf, Alexander; Lachmayer, Roland (Erlangen : Deutsche Gesellschaft für angewandte Optik, 2016)
    Laser based remote phosphor light sources offer a very high brightness but are significantly influenced by the temperature of the phosphor conversion ceramic as well as self-absorption effects. This paper discusses both ...
  • Baake, E.; Jakovics, A.; Pavlovs, S.; Kirpo, M. (Bingley : Emerald Group Publishing Ltd., 2011)
    Purpose - The purpose of this paper is to present in-depth numerical modelling of heat and mass exchange in industrial induction channel furnace (ICF). Design/methodology/approach - The turbulent heat and mass exchange in ...
  • Hofmann, Martin; Seckmeyer, Gunther (Basel : MDPI AG, 2017)
    We analyze the output of various state-of-The-Art irradiance models for photovoltaic systems. The models include two sun position algorithms, three types of input data time series, nine diffuse fraction models and five ...
  • Denkena, Berend; Grove, Thilo; Dittrich, Marc-André; Niederwestberg, D.; Lahres, M. (Amsterdam : Elsevier, 2015)
    In analysis of machining processes, finite element analysis is widely used to predict forces, stress distributions, temperatures and chip formation. However, constitutive models are not always available and simulation of ...
  • Gerstein, G.; Isik, K.; Gutknecht, F.; Sieczkarek, P.; Ewert, J.; Tekkaya, A.E.; Clausmeyer, T.; Nürnberger, F. (Bristol : Institute of Physics Publishing, 2017)
    The evolution of damage in geared components manufactured from steel sheets was investigated, to analyse the influence of damage caused by the sheet-bulk-metal forming. Due to the inhomogeneous and multi-axial deformation ...
