  • Multifocal diffractive lens generating several fixed foci at different design wavelengths 
    Doskolovich, Leonid L.; Bezus, Evgeni A.; Morozov, Andrey A.; Osipov, Vladimir; Wolffsohn, James S.; Chichkov, Boris (Washington, DC : Optical Society of America, 2018)
    We propose a method for designing multifocal diffractive lenses generating prescribed sets of foci with fixed positions at several different wavelengths. The method is based on minimizing the difference between the complex ...
  • Nature-based solutions and mental health 
    Kabisch, Nadja; Basu, Sukanya; van den Bosch, Matilda; Bratman, Gregory N.; Masztalerz, Oskar (Cheltenham, UK : Edward Elgar Publishing, 2023)
    This chapter demonstrates the mental health benefits of nature-based solutions in cities. First, factors that determine urban mental health and adverse health effects of environmental stressors in cities are explained. ...
  • On the design of terminal ingredients for data-driven MPC 
    Berberich, Julian; Köhler, Johannes; Müller, Matthias A.; Allgöwer, Frank (Frankfurt ; München [u.a.] : Elsevier, 2021)
    We present a model predictive control (MPC) scheme to control linear time-invariant systems using only measured input-output data and no model knowledge. The scheme includes a terminal cost and a terminal set constraint ...
  • Optimized design of mixed flow compressors for an active high-lift system 
    Teichel, Sönke (Hannover : Institut für Turbomaschinen und Fluid-Dynamik, 2018)
    To support an active high-lift system for future civil aircraft small, electrically powered compressors are required, which exceed the current state of the art concerning stage loading and compactness. To satisfy the ...
  • Optimized designing of a patch phased array with a MoM-solver 
    Wang, Yuanhao; Berens, Michael; Nietsch, Alexander; John, Werner; Mathis, Wolfgang (Bingley : Emerald Group Publishing Ltd., 2014)
    Purpose - The purpose of this paper is to present an optimization process for the design of a 2×2 patch antenna phased array with application for an UHF RFID system. Design/methodology/approach - The optimization process ...
  • Precise fabrication of ultra violet dielectric dispersion compensating mirrors 
    Willemsen, Thomas; Schlichting, S.; Kellermann, T.; Jupé, Marco; Ehlers, H.; Morgner, Uwe; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    The present contribution is concentrated on an improved method to manufacture dielectric dispersion compensating mirrors in the ultra violet (UV) range by applying a novel online phase monitoring device. This newly developed ...
  • Probabilistic fatigue analysis of jacket support structures for offshore wind turbines exemplified on tubular joints 
    Kelma, Sebastian; Schaumann, Peter (Amsterdam : Elsevier, 2015)
    The design of offshore wind turbines is usually based on the semi-probabilistic safety concept. Using probabilistic methods, the aim is to find an advanced structural design of OWTs in order to improve safety and reduce ...
  • Proceedings of the 11th European Workshop on Aircraft Design Education 
    European Workshop on Aircraft Design Education (EWADE) (Linköping : EWADE, 2013)
    These are the Proceedings of the 11th European Workshop on Aircraft Design Education (in short: EWADE 2013). The workshop took place from 17. to 19.09.2013 in Linköping, Sweden. EWADE 2013 was for the first time integrated ...
  • Process design for 5-axis ball end milling using a real-time capable dynamic material removal simulation 
    Denkena, Berend; Pape, O.; Krödel, A.; Böß, V.; Ellersiek, L.; Mücke, A. (Heidelberg : Springer, 2021)
    For repairing turbine blades or die and mold forms, additive manufacturing processes are commonly used to build-up new material to damaged sections. Afterwards, a subsequent re-contouring process such as 5-axis ball end ...
  • Shifting value stream patterns along the product lifecycle with digital twins 
    Schleich, Benjamin; Dittrich, Marc-André; Clausmeyer, Till; Damgrave, Roy; Erkoyuncu, John Ahmet; Haefner, Benjamin; de Lange, Jos; Plakhotnik, Denys; Scheidel, Wieben; Wuest, Thorsten (Amsterdam [u.a.] : Elsevier, 2019)
    The concept of digital twins promises high potentials for product design, manufacturing, user experience and recycling. Thus, digital twins have received increasing interest in academia and industry. However, the actual ...
  • Simulation and Design of an Orientation Mechanism for Assembly Systems 
    Krebs, Daniel; Borchert, Gunnar; Raatz, Annika (Amsterdam : Elsevier B.V., 2016)
    The article focuses on methods for designing modular cable-driven orientation mechanisms that can be attached to robot systems that lack on rotational degrees of freedom. The approach yields assembly systems for high speed ...
