    • An error estimator for real-time simulators based on model order reduction 

      Alfaro, Icíar; González, David; Zlotnik, Sergio; Díez, Pedro; Cueto Prendes, Elias; Chinesta, Francisco (Springer, 2015-11-26)
      Article
      Accés obert
      Model order reduction (MOR) is one of the most appealing choices for real-time simulation of non-linear solids. In this work a method is presented in which real time performance is achieved by means of the o -line solution ...

    • Attitude control for satellites flying in VLEO using aerodynamic surfaces 

      Cañas Muñoz, Valentin; González, David; Becedas, Jonathan; Rodríguez Donaire, Silvia; García-Almiñana, Daniel; Sureda Anfres, Miquel; Nieto, Miriam; Muñoz, Candia (British Interplanetary Society, 2020)
      Article
      Accés restringit per política de l'editorial
      This paper analyses the use of aerodynamic control surfaces, whether passive or active, in order to carry out very low Earth orbit (VLEO) attitude maneuver operations. Flying a satellite in a very low Earth orbit with an ...

    • Effect of the separated approximation of input data in the accuracy of the resulting PGD solution 

      Zlotnik, Sergio; Díez, Pedro; González, David; Huerta, Antonio (Springer, 2015-11-25)
      Article
      Accés obert
      The Proper Generalized Decomposition (PGD) requires separability of the input data (e.g. physical properties, source term, boundary conditions, initial state). In many cases the input data is not expressed in a separated ...

    • On-line resistance measurement of substation connectors focused on predictive maintenance 

      Kadechkar, Akash; Riba Ruiz, Jordi-Roger; Moreno Eguilaz, Juan Manuel; Capelli, Francesca; González, David (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Comunicació de congrés
      Accés obert
      To detect faults in their early stage in a substation, it is necessary to monitor, measure and analyze periodically the health condition of the electrical connectors, which are among the most critical devices in such ...

    • Optimization of short-circuit tests based on finite element analysis 

      Capelli, Francesca; Riba Ruiz, Jordi-Roger; González, David (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      One of the main problems that arises when performing short-circuit tests to large loops involving substation connectors is the inductive component of the loop impedance. Transformers used to perform short-circuit tests ...

    • PGD-based “Computational Vademecum” for efficient design, optimization and control 

      Chinesta, Francisco; Leygue, Adrien; Bordeu, F.; Cueto Prendes, Elias; González, David; Alfaro, Icíar; Ammar, Amine; Huerta, Antonio; Díez, Pedro (2013)
      Article
      Accés restringit per política de l'editorial
      D espite the impressive progresses attained by simulation capabilities and techniques, some challenging problems remain today intractable. These prob- lems, that are common to many branches of science and engineering, ...
