    • A personal account of Turing’s imprint on the development of computer science 

      Díaz Cort, Josep; Torras, Carme (Elsevier, 2012)
      Article
      Accés obert
      The rst part of the XX century saw the development of the digital computer and the eld of computer science. In the present paper, we sketch our vision of that period and of the role that Alan Turing and some of his ...

    • A virtual actuator approach for the secure control of networked LPV systems under pulse-width modulated DoS attacks 

      Rotondo, Damiano; Sánchez, Helem Sabina; Puig Cayuela, Vicenç; Escobet Canal, Teresa; Quevedo Casín, Joseba Jokin (2019-01-01)
      Article
      Accés obert
      In this paper, we formulate and analyze the problem of secure control in the context of networked linear parameter varying (LPV) systems. We consider an energy-constrained, pulse-width modulated (PWM) jammer, which corrupts ...

    • Anytime inference with distilled hierarchical neural ensembles 

      Ruiz Ovejero, Adrià; Verbeek, Jakob (2021)
      Text en actes de congrés
      Accés obert
      Inference in deep neural networks can be computationally expensive, and networks capable of anytime inference are important in mscenarios where the amount of compute or quantity of input data varies over time. In such ...

    • Computation of independent contact regions for grasping 3-D objects 

      Roa Garzón, Máximo; Suárez Feijóo, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2009-08)
      Article
      Accés obert
      Precision grasp synthesis has received a lot of attention in past few last years. However, real mechanical hands can hardly assure that the fingers will precisely touch the object at the computed contact points. The concept ...

    • DAE Methods in Constrained Robotic System Simulation: 

      Costa Castelló, Ramon; Griñó Cubero, Robert; Basañez Villaluenga, Luis (Centro de Investigación en Computación, 1998-03)
      Article
      Accés obert
      In this paper a DAE formulation is used to model the behaviour of constrained robotic systems. This formulation allows to specify in an easy and clear way the constrained behaviour of a robotic system. In order to better ...

    • Detection of replay attacks in CPSs using observer-based signature compensation 

      Trapiello Fernández, Carlos; Rotondo, Damiano; Sánchez Corrales, Helem Sabina; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Text en actes de congrés
      Accés obert
      This paper presents a replay attack detection method that addresses the performance loss of watermarking-based approaches. The proposed method injects a sinusoidal signal that affects a subset, chosen at random, of the ...

    • Detection of replay attacks in cyber-physical systems using a frequency-based signature 

      Sánchez Corrales, Helem Sabina; Rotondo, Damiano; Escobet Canal, Teresa; Puig Cayuela, Vicenç; Saludes Closa, Jordi; Quevedo Casín, Joseba Jokin (2019-03-01)
      Article
      Accés obert
      This paper proposes a frequency-based approach for the detection of replay attacks affecting cyber-physical systems (CPS). In particular, the method employs a sinusoidal signal with a time-varying frequency (authentication ...

    • Dynamic equations of motion for a 3-bar tensegrity based mobile robot 

      Mirats Tur, Josep Maria; Hernández, Sergi; Graells, Albert (IEEE, 2007)
      Text en actes de congrés
      Accés obert
      Tensegrity structures can give a new approach to the construction of mobile robots with different shapes and properties that usual robots, wheeled or legged, do not have. Tensegrity are light, deformable structures that ...

    • Generating predicate suggestions based on the space of plans: an example of planning with preferences 

      Canal Camprodon, Gerard; Torras, Carme; Alenyà Ribas, Guillem (2023-05-31)
      Article
      Accés obert
      Task planning in human–robot environments tends to be particularly complex as it involves additional uncertainty introduced by the human user. Several plans, entailing few or various differences, can be obtained to solve ...

    • Onto computing the uncertainty for the odometry pose estimate of a mobile robot 

      Mirats Tur, Josep Maria (IEEE, 2007)
      Text en actes de congrés
      Accés obert
      Solving the navigation issue for a mobile robot in a 2D space requires using internal and external sensors, so researchers try to fuse data from different sensors using methods as for example Kalman filtering. Those methods ...

    • Reachability and stabilization of scheduled steady-states for LPV single-input systems 

      Corona, Dario; Cristofaro, Andrea; Rotondo, Damiano (2019-05-01)
      Article
      Accés obert
      The aim of this work is characterizing the class of LPV systems that admit steady-state trajectories depending exclusively on the scheduling parameter. In particular, it will be shown that only certain parameter dependent ...
