  • The Few-get-richer: a surprising consequence of popularity-based rankings
    Germano, Fabrizio; Gómez, Vicenç; Le Mens, Gaël (ACM Association for Computer Machinery, 2019)
    Ranking algorithms play a crucial role in online platforms ranging from search engines to recommender systems. In this paper, we identify a surprising consequence of popularity-based rankings: the fewer the items reporting ...
  • Interactive discovery system for direct democracy
    Aragón, Pablo; Bermejo, Yago; Gómez, Vicenç; Kaltenbrunner, Andreas (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Decide Madrid is the civic technology of Madrid City Council which allows users to create and support online petitions. Despite the initial success, the platform is encountering problems with the growth of petition signing ...
  • Target wake time: scheduled access in IEEE 802.11ax WLANs
    Nurchis, Maddalena; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    The increasing interest in ubiquitous networking, and the tremendous popularity gained by IEEE 802.11 WLANs in recent years, is leading to very dense deployments where high levels of channel contention may prevent meeting ...
  • 3D reconstruction of both shape and bone mineral density distribution of the femur from DXA images
    Humbert, Ludovic; Whitmarsh, Tristan; De Craene, Mathieu; del Río Barquero, Luis Miguel; Fritscher, Karl; Schubert, Rainer; Eckstein, Felix; Link, Thomas; Frangi Caregnato, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2010)
  • 3D bone mineral density distribution and shape reconstruction of the proximal femur from a single simulated DXA image: an in vitro study
    Whitmarsh, Tristan; Humbert, Ludovic; De Craene, Mathieu; del Río Barquero, Luis Miguel; Fritscher, Karl; Schubert, Rainer; Eckstein, Felix; Link, Thomas; Frangi Caregnato, Alejandro (Society of Photo Optical Instrumentation Engineers (SPIE), 2010)
    Area Bone Mineral Density (aBMD) measured by Dual-energy X-ray Absorptiometry (DXA) is an established criterion in the evaluation of hip fracture risk. The evaluation from these planar images, however, is limited to 2D ...
