    Mantovani, Filippo; Garcia Gasulla, Marta; Gracia, Jose; Stafford, Esteban; Banchelli Gracia, Fabio; Josep Fabregó, Marc; Criado Ledesma, Joel; Nachtmann, Mathias (Elsevier, 2020-11)
    Article
    Restricted access - publisher's policy
    In this paper, we analyze the performance and energy consumption of an Arm-based high-performance computing (HPC) system developed within the European project Mont-Blanc 3. This system, called Dibona, has been integrated ...
  • Benchmarking of state-of-the-art HPC clusters with a production CFD code 

    Banchelli Gracia, Fabio; Garcia Gasulla, Marta; Houzeaux, Guillaume; Mantovani, Filippo (Association for Computing Machinery (ACM), 2020)
    Conference report
    Open Access
    Computing technologies populating high-performance computing (HPC) clusters are getting more and more diverse, offering a wide range of architectural features. As a consequence, efficient programming of such platforms ...
  • Photovoltaic inverters with fault ride-through capability 

    Azevedo, Gustavo M.S.; Vázquez, Gerardo; Luna Alloza, Álvaro; Aguilar Galván, Daniel; Rolán Blanco, Alejandro (ISIE, 2009)
    Conference lecture
    Open Access
    This paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in ...
  • Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability 

    Aguilar Galván, Daniel; Rolán Blanco, Alejandro; Vázquez, Gerardo; Córcoles López, Felipe; Rodríguez Cortés, Pedro (2009)
    Conference lecture
    Open Access
    This paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ...
  • Behavior of the three-phase induction motor with spiral sheet rotor 

    Mujal-Rosas, Ramon Maria; Boix Aragonès, Oriol; Colom Fajula, Xavier; Rolán Blanco, Alejandro (2009-03)
    Article
    Open Access
    Improvements in torque at low currents using a rotor with spiral sheets are analyzed. Several rotors and stators have been built combining different constructive and mechanical characteristics of the related elements: ...
  • Reduced-order models of squirrel-cage induction generators for fixed-speed wind turbines under unbalanced grid conditions 

    Rolán Blanco, Alejandro; Córcoles López, Felipe; Bogarra Rodríguez, Santiago; Monjo Mur, Lluís; Pedra Durán, Joaquim (2016-06)
    Article
    Open Access
    This paper develops a study of reduced-order models for squirrel-cage induction generators used in the fixed-speed wind turbines. The squirrel-cage of these generators must be modeled with a double-cage for accuracy purposes. ...
  • Sustainability at the Technical University of Catalonia 

    Grau Saldes, Antoni (2020-05)
    Article
    Open Access
    The Technical University of Catalonia (UPC) has a large tradition of including Sustainable Development in its technical degrees. Although UPC does not offer degrees in social sciences or humanities, Education for Sustainable ...
  • Cooperative visual-SLAM system for UAV-based target tracking in GPS-denied environments: a target-centric approach 

    Trujillo, Juan Carlos; Munguía Alcalá, Rodrigo Francisco; Urzúa Sarquis, Isidro; Grau Saldes, Antoni (2020-05-15)
    Article
    Open Access
    Autonomous tracking of dynamic targets by the use of Unmanned Aerial Vehicles (UAVs) is a challenging problem that has practical applications in many scenarios. In this context, a fundamental aspect that must be addressed ...
  • Automated chlorine dosage in a simulated drinking water treatment plant: a real case study 

    Gámiz Caro, Javier Francisco; Grau Saldes, Antoni; Martínez García, Herminio; Bolea Monte, Yolanda (Multidisciplinary Digital Publishing Institute, 2020-06-11)
    Article
    Open Access
    In this paper, we present a simulator of a drinking water treatment plant. The model of the plant was based in hydraulic and matter transportation models. In order to not introduce more inaccuracies in the simulation, the ...
  • Outdoor delayed-state visually augmented odometry 

    Illa, Viorela Simona; Andrade-Cetto, Juan; Sanfeliu Cortés, Alberto (IFAC, 2007)
    Conference report
    Open Access
    This paper presents an efficient approach to outdoor visually augmented odometry. The technique computes relative pose constraints via a robust least squares minimisation of 3D point correspondences, which are in turn ...
  • Vision-based loop closing for delayed state robot mapping 

    Illa, Viorela Simona; Andrade-Cetto, Juan; Valencia Carreño, Rafael; Sanfeliu Cortés, Alberto (2007)
    Conference report
    Open Access
    This paper shows results on outdoor vision-based loop closing for Simultaneous Localization and Mapping. Our experiments show that for loops of over 50m, the pose estimates maintained with a Delayed-State Extended Information ...
