      © 2016 The Authors. Calcium phosphate cements (CPCs) are widely used in bone repair. Currently there are two main types of CPCs, brushite and apatite. The aim of this project was to evaluate the mechanical properties of ...
    • Connect the dot: computing feed-links for network extension 

      Speckmann, Bettina; Silveira, Rodrigo Ignacio; Aronov, Boris; Buchin, Kevin; Buchin, Maike; Jansen, Bart; De Jong, Tom; Kreveld, Marc van; Loffler, Maarten; Luo, Jun (2011-12-20)
      Article
      Open Access
      Road network analysis can require distance from points that are not on the network themselves. We study the algorithmic problem of connecting a point inside a face (region) of the road network to its boundary while ...

      Motivated by a technique in privacy protection, in which n points are randomly perturbed by at most a distance r, we study the following problem: Given n points and m circles in the plane, what is the maximum r such that ...
    • Processing aggregated data : the location of clusters in health data 

      Buchin, Kevin; Buchin, Maike; Kreveld, Marc van; Löffler, Maarten; Luo, Jun; Silveira, Rodrigo Ignacio (2012-07)
      Article

      Spatially aggregated data is frequently used in geographical applications. Often spatial data analysis on aggregated data is performed in the same way as on exact data, which ignores the fact that we do not know the actual ...
    • White dwarf-main sequence binaries from LAMOST: the DR5 catalogue 

      Ren, J. J.; Rebassa Mansergas, Alberto; Parsons, S. G.; Liu, X. W; Luo, Jun; Kong, X; Zhang, C. (Oxford University Press, 2018-07-01)
