    • A nonlinear predictive control approach for urban drainage networks using data-driven models and moving horizon estimation 

      Mark Balla, Krisztian; Schou, Christian; Dimon Bendtsen, Jan; Ocampo-Martínez, Carlos; Kallesøe, Carsten Skovmose (Institute of Electrical and Electronics Engineers (IEEE), 2022-01-01)
      Article
      Accés obert
      Real-time control (RTC) of urban drainage networks (UDNs) is a complex task where transport flows are non-pressurized and therefore impose flow-dependent time delays in the system. Unfortunately, the installation of flow ...

      Oller Piqué, Ramón; Gómez Melis, Guadalupe (Oxford University Press, 2020-10-01)
      Article
      Accés obert
      Many biomedical studies focus on the association between a longitudinal measurement and a time-to-event outcome while quantifying this association by means of a longitudinal-survival joint model. In this article we propose ...
    • A nonparametric visual test of mixed hazard models 

      Spreeuw, Jaap; Perch Nielsen, Jens; Fiig Jarner, Søren (Institut d'Estadística de Catalunya, 2014-01-02)
      Article
      Accés obert
      We consider mixed hazard models and introduce a new visual inspection technique capable of detecting the credibility of our model assumptions. Our technique is based on a transformed data approach, where the density of the ...

      We characterize the traceability properties of linear codes. It is well known that any code of length n and minimum distance d is a c-TA code if c 2¿<¿n/(n¿-¿d). In this paper, we show that a less restrictive condition can ...
