• openAccess   Integration of Static and Self-motion-Based Depth Cues for Efficient Reaching and Locomotor Actions 

      Grzyb, Beata J.; Castelló, Vicente; del Pobil, Angel P.; Antonelli, Marco Springer Berlin Heidelberg (2012)
      The common approach to estimate the distance of an object in computer vision and robotics is to use stereo vision. Stereopsis, however, provides good estimates only within near space and thus is more suitable for reaching ...
    • openAccess   Investigación práctica en educación : investigación-acción 

      Marqués-Andrés, Mercedes; Ferrandez-Berrueco, Reina TICAI, Sociedad de Educación (2012)
      This paper describes the methodology of action research, an educational research methodology in which professors investigate on their own teaching practices. In this work we also justify the need of using such methodology ...
    • closedAccess   Leveraging Task-Parallelism in Energy-Efficient ILU Preconditioners 

      Aliaga Estellés, José Ignacio; Dolz, Manuel F.; Martín Huertas, Alberto F.; Mayo, Rafael; Quintana-Orti, Enrique S. Springer Berlin Heidelberg (2012)
      We analyze the energy-performance balance of a task-parallel computation of an ILU-based preconditioner for the solution of sparse linear systems on multi-core processors. In particular, we elaborate a theoretical model ...
    • openAccess   On the Rationality of Explanations in Classification Algorithms 

      Falomir, Zoe; Costa, Vicent IOS Press (2021)
      This paper is a first step towards studying the rationality of explanations produced by up-to-date AI systems. Based on the thesis that designing rational explanations for accomplishing trustworthy AI is fundamental for ...
    • closedAccess   Parallelization of Multilevel ILU Preconditioners on Distributed-Memory Multiprocessors 

      Aliaga Estellés, José Ignacio; Bollhöfer, Matthias; Martín Huertas, Alberto F.; Quintana-Orti, Enrique S. Springer Berlin Heidelberg (2012)
      In this paper we investigate the parallelization of the ILUPACK library for the solution of sparse linear systems on distributed-memory multiprocessors. The parallelization approach employs multilevel graph partitioning ...
    • openAccess   Plastic Representation of the Reachable Space for a Humanoid Robot 

      Antonelli, Marco; Grzyb, Beata J.; Castelló, Vicente; del Pobil, Angel P. Springer Berlin Heidelberg (2012)
      Reaching a target object requires accurate estimation of the object spatial position and its further transformation into a suitable arm-motor command. In this paper, we propose a framework that provides a robot with a ...
    • closedAccess   Revisiting the Gauss-Huard Algorithm for the Solution of Linear Systems on Graphics Accelerators 

      Benner, Peter; Ezzatti, Pablo; Quintana-Orti, Enrique S.; Remón, Alfredo Springer (2016-04-02)
      In 1979, P. Huard presented an efficient variant of the Gauss-Jordan elimination for the solution of linear systems. In particular, this alternative algorithm exhibits the same computational cost as the traditional LU-based ...
