  • Comparative study of reactive power control methods for photovoltaic inverters in low-voltage grids 

    Momeneh, Arash; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Martí Colom, Pau; Velasco García, Manel (2016-03-01)
    Article
    Open Access
    The increasing installation of photovoltaic panels in low-voltage grids causes an over voltage problem, especially during high production and low consumption periods. Generally the over voltage problem is overcome by ...

    Muñoz Morgado, Luis Miguel (2016-03-07)
    Article
    Open Access
    A description about how the ISO norm 9241-9 is useful evaluating the ergonomics in interaction with computers.
  • Método multiobjetivo de aprendizaje para razonamiento inductivo difuso 

    Acosta, Jesús; Nebot Castells, M. Àngela; Fuertes Armengol, José Mª (2006-10)
    External research report
    Open Access
    It has been recognized in various studies that the variations in the granularity (number of classes per variable) and the membership functions have a significant effect in the behaviour of the fuzzy systems. The FIR ...
  • Sensorless force estimation using a neuro-vision-based approach for robotic-assisted surgery 

    Avilés Rivero, Angélica Ivone; Alsaleh, Samar M.; Sobrevilla Frisón, Pilar; Casals Gelpi, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference lecture
    Open Access
    This paper addresses the issue of lack of force feedback in robotic-assisted minimally invasive surgeries. Force is an important measure for surgeons in order to prevent intra-operative complications and tissue damage. ...
  • Force-feedback sensory substitution using supervised recurrent learning for robotic-assisted surgery 

    Avilés Rivero, Angélica; Alsaleh, Samar M.; Sobrevilla Frisón, Pilar; Casals Gelpi, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report

    The increasing deployment of distributed generation (DG) such as photovoltaic panels (PV) connected to low-voltage (LV) grids is becoming a common trend in urban areas. The advances of information and communication technology ...
  • Optimal-sampling-inspired self-triggered control 

    Velasco García, Manel; Martí Colom, Pau; Bini, Enrico (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    Self-triggered control is an appealing sampling strategy that promises to preserve the same control performance as traditional (periodic) sampling, yet consuming less computing resource by executing the controller less ...
  • Compliant gait assistance triggered by user intention 

    Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpi, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    An automatic gait initialization strategy based on user intention sensing in the context of rehabilitation with a lower-limb wearable robot is proposed and evaluated. The proposed strategy involves monitoring the human-orthosis ...
  • Adaptive walking assistance based on human-orthosis interaction 

    Rajasekaran, Vijaykumar; Aranda López, Juan; Casals Gelpi, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    An assistive rehabilitation strategy for a lower-limb wearable robot is proposed and evaluated. The control strategy monitors the human-orthosis interaction torques and modifies the orthosis operation mode depending on its ...
