    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 ...
  • 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 ...
  • Distributed cooperative control for stepper motors synchronization 

    Yague, Sauro J.; Reyes Carmenaty, Guillermo; Rolán Blanco, Alejandro; Garcia Cerrada, Aurelio (2018)
    Conference report
    Open Access
    This paper describes the design and simulation of a distributed cooperative control algorithm based on multi-agents to synchronize a group of stepper motors. Modeling of the two-phase hybrid stepper motor in closed loop ...
  • Peachy Parallel Assignments (EduHPC 2018) 

    Ayguadé Parra, Eduard; Álvarez Martí, Lluc; Banchelli Gracia, Fabio; Burtscher, Martin; González Escribano, Arturo; Gutiérrez Monge, Julián; Joiner, David A.; Kaeli, David; Previlon, Fritz; Rodríguez Gutiez, Eduardo; Bunde, David P. (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    Peachy Parallel Assignments are a resource for instructors teaching parallel and distributed programming. These are high-quality assignments, previously tested in class, that are readily adoptable. This collection of ...
  • Performance study of HPC applications on an Arm-based cluster using a generic efficiency model 

    Banchelli Gracia, Fabio; Peiró Conde, Kilian; Querol de Porras, Andrea; Ramírez Gargallo, Guillem; Ramírez Miranda, Guillem; Vinyals Ylla-Català, Joan; Vizcaino Serrano, Pablo; Garcia Gasulla, Marta; Mantovani, Filippo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    HPC systems and parallel applications are increasing their complexity. Therefore the possibility of easily study and project at large scale the performance of scientific applications is of paramount importance. In this ...
  • Observer design for Takagi-Sugeno Lipschitz systems affected by disturbances using quadratic boundedness 

    Yang, Ruicong; Rotondo, Damiano; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    In this paper, a proportional observer design using quadratic boundedness is proposed in order to estimate the state of a system described by a Takagi-Sugeno model with a Lipschitz nonlinearity term, and affected by unknown ...
  • 3DPeople: modeling the geometry of dressed humans 

    Pumarola Peris, Albert; Sánchez Riera, Jordi; Choi, Gary; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (2019)
    Conference report
    Open Access
    Recent advances in 3D human shape estimation build upon parametric representations that model very well the shape of the naked body, but are not appropriate to represent the clothing geometry. In this paper, we present an ...
  • Economic MPC-LPV control for the operational management of water distribution networks 

    Karimi Pour, Fatemeh; Puig Cayuela, Vicenç; Cembrano Gennari, Gabriela (Elsevier, 2019)
    Conference report
    Open Access
    This paper presents an Economic Model Predictive Control (EMPC) for the operational management of water distribution networks (WDNs) with periodic operation based on embedding the nonlinearity of the model to the Linear ...
  • Set-based replay attack detection in closed-loop systems using a plug & play watermarking approach 

    Trapiello Fernández, Carlos; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    This paper presents a watermarking signal injection method that compensates its effect in the loop, avoiding thus the signal reinjection. Similar to a virtual actuator scheme, the proposed methodology masks the presence ...
