  • Ahrens, M.; Fischer, R.; Dagen, M.; Denkena, Berend; Ortmaier, Tobias (Amsterdam : Elsevier, 2013)
    Using conventional grinding wheels, wheel-sided chatter vibration is one of the limiting factors in terms of productivity and surface finish. Initial vibration related to the dynamic behavior of the machine tool copy on ...
  • Ahrens, M.; Dagen, M.; Denkena, Berend; Ortmaier, Tobias (Amsterdam : Elsevier, 2016)
    Using conventional grinding wheels, self-excited vibrations are one of the most limiting factors in terms of productivity and process stability in cylindrical plunge grinding. Depending on the dynamic behavior of the ...
  • Needleman, David Berney; Wagner, Hannes; Altermatt, Pietro P.; Buonassisi, Tonio (Amsterdam : Elsevier, 2015)
    Advanced solar cell architectures like passivated emitter and rear (PERC) and heterojunction with intrinsic thin layer (HIT) are increasingly sensitive to bulk recombination. Present device models consider homogeneous bulk ...
  • Denkena, Berend; Dittrich, Marc-André; Uhlich, Florian (Amsterdam : Elsevier B.V., 2016)
    New integrated sensors and connected machine tools generate a tremendous amount of in-depth process data. The continuous transformation of the obtained data into deployable machining knowledge allows for faster ramp-ups, ...
  • Klinger, T.; Heipke, Christian; Ott, N.; Schenke, H.W.; Ziems, M. (London : International Society for Photogrammetry and Remote Sensing, 2010)
    In this paper we present an automatic approach for coastline detection from images which is based on parametric active contours (snakes). Snakes require the definition of an energy functional that reflects the underlying ...
  • Ahrens, M.; Damm, J.; Dagen, M.; Denkena, Berend; Ortmaier, T. (Amsterdam : Elsevier BV, 2017)
    Using conventional grinding wheels, self-excited vibrations are one of the most limiting factors in terms of productivity and process stability in cylindrical plunge grinding. Depending on the dynamic behavior of the ...
  • 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 ...
  • Stahlmann, Arne; Schlurmann, Torsten (Reston : American Society of Civil Engineers, 2012)
    Regarding offshore constructions, there is still a lack in knowledge of scour progression for complex structures like foundations for offshore wind energy converters at present, which is however necessary for its dimensioning. ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    The development of laser-based lighting systems has been the latest step towards a revolution in illumination technology brought about by solid-state lighting. Laser-activated remote phosphor systems produce white light ...
  • Möhring, H.-C.; Kayapinar, H.; Denkena, Berend (Amsterdam : Elsevier BV, 2012)
    In this paper multi-scale modeling of a novel fluid dynamic planar positioning system is described and compared with a simplified plant model. The multi-scale model is realized by coupling a mechatronic simulation model ...
  • Turowski, Marcus; Jupé, Marco; Melzig, Thomas; Pflug, Andreas; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    A multiple scale model approach is presented in order to investigate Al2O3 thin film growth in the framework of an existing Ion Beam Sputtering (IBS) coating process. Therefore, several simulation techniques are combined ...
  • Ziems, M.; Fujimura, H.; Heipke, Christian; Rottensteiner, Franz (London : International Society for Photogrammetry and Remote Sensing, 2010)
    This paper describes a semi-automatic system for road verification from high resolution orthophotos in an urban context. The system combines several road detection and road verification approaches from current literature ...
  • Goseberg, Nils; Schlurmann, Torsten (Reston : American Society of Civil Engineers, 2010)
    This research study considers long wave run-up experimentally and numerically. At first, an alternative methodology in long wave physical modeling is presented by means of a set of pipe pumps forcing the inflow of a ...
  • Jupé, Marco; Willemsen, Thomas; Malobabic, Sina; Schuba, Kornelia; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    During the last years, optical low loss components gained more and more industrial interest and led to novel approaches for the production in optical coating technology. The application of filtered deposition technologies ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    A new family of lighting products is developed as laser diodes replace LEDs in the remote phosphor configuration. The resulting lighting systems, also known as laser-excited remote phosphor systems, exhibit advanced ...
  • Stahlmann, Arne; Schlurmann, Torsten (Reston : American Society of Civil Engineers, 2010)
    As a step to further develop the share of renewable energies, the first German offshore test site alpha ventus has been installed in the North Sea in 2009 in water depths of 30 m, where experience shall be gained and made ...
