  • Mapping similarities in temporal parking occupancy behavior based on city-wide parking meter data 
    Bock, Fabian; Xia, Karen; Sester, Monika (Göttingen : Copernicus GmbH, 2018)
    The search for a parking space is a severe and stressful problem for drivers in many cities. The provision of maps with parking space occupancy information assists drivers in avoiding the most crowded roads at certain ...
  • Mechanical properties of femoral trabecular bone in dogs 
    Pressel, Thomas; Bouguecha, Anas; Vogt, Ute; Meyer-Lindenberg, Andrea; Behrens, Bernd-Arno; Nolte, Ingo; Windhagen, Henning (London : BioMed Central Ltd., 2005)
    Background: Studying mechanical properties of canine trabecular bone is important for a better understanding of fracture mechanics or bone disorders and is also needed for numerical simulation of canine femora. No detailed ...
  • A Method to Distinguish Potential Workplaces for Human-Robot Collaboration 
    Blankemeyer, Sebastian; Recker, Tobias; Stuke, Tobias; Brokmann, Jens; Raatz, Annika; Oubari, Assem; Pischke, Dennis; Reiniger, Michael; Geese, Markus (Amsterdam : Elsevier B.V., 2018)
    The high dynamics of globalized markets and their increase in competition, as well as the demographic changes in western countries causing an increasing shortage of skilled personnel are resulting in major challenges for ...
  • Multi-cluster complexes 
    Ceballos, Cesar; Labbé, Jean-Philippe; Stump, Christian (Nancy : French Association for Discrete Mathematics & Theoretical Computer Science, 2012)
    We present a family of simplicial complexes called multi-cluster complexes. These complexes generalize the concept of cluster complexes, and extend the notion of multi-associahedra of types A and B to general finite Coxeter ...
  • Multi-layer visualization of mobile mapping data
