  • A fault detection method for pitch actuators faults in wind turbines 

    Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Rodellar Benedé, José (2015)
    Conference report
    Open Access
    The paper presents a model-based fault detection method for pitch actuators faults using the normalized gradient method to estimate the parameters of the pitch actuator. One major difficulty is that the input signal to the ...
  • Evaluating an E-portfolio for a linear algebra course using rubrics 

    García Planas, María Isabel; Taberna Torres, Judit; Domínguez García, Santiago; Palau, Ramon (International Association of Technology, Education and Development (IATED), 2009)
    Conference lecture
    Open Access
    There is always a need to evaluate training skills acquired for, in this way, to know whether they have achieved the learning objectives. The use of the e-portfolio becomes more common among teachers then, becomes ...
  • Using the e-portfolio for large groups of students 

    García Planas, María Isabel; Taberna Torres, Judit; Domínguez García, Santiago; Palau, Ramon (International Association of Technology, Education and Development (IATED), 2015)
    Conference lecture
    Open Access
    The number of students in class in studies of first year engineering degree in many Universities, in particular at the Polytechnic University of Catalonia, is high with an average of 75 students per class. While the large ...
  • Differential flatness of a class of n—DOF planar manipulators driven by an arbitrary number of actuators 

    Franch Bullich, Jaume; Reyes Jimenez, Alejandro; Agrawal, Sunil K. (2013)
    Conference report

    This paper deals with the problem of feedback linearization, either by dynamic or static feedback, of a planar robot manipulator with n links and m inputs. The robot is pro-vided with a particular inertia distribution in ...
  • Characterization of coastal upwelling events during the generation of the water column stratification in spring (Vilanova i la Geltrú, NW Mediterranean) 

    Antonijuan Rull, Josefina; Guillem, Jorge; Simarro, Gonzalo; Nogueras Cervera, Marc; Río Fernandez, Joaquín del (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    This article presents some preliminary results on the characterization of inputs of offshore waters (upwelling events) in the coast off Vilanova i la Geltrú (NW Mediterranean) in the spring of the years 2010, 2012 and 2014. ...
  • Análisis de datos y clasificación del sector del autobús interurbano en Catalunya

  • A note on multinomial (probabilistic) values 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2015)
    Conference lecture
    Open Access
    The work tries to contribute to a better understanding of multinomial values as a consistent alternative or complement to classical values (Shapley and Banzhaf). We compare the behavior of multinomial values with respect ...
  • On computing flat outputs through Goursat normal form 

    Franch Bullich, Jaume; Manzanera, Ana; Valero, Gemma (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    This paper is devoted to computation of flat outputs by means of the Goursat normal form of the Pfaffian system associated to any control system in state space form. The algorithm explained here consists in three steps: ...

  • Novel ionospheric activity indicator specifically tailored for GNSS users 

    Sanz Subirana, Jaume; Juan Zornoza, José Miguel; González Casado, Guillermo; Prieto Cerdeira, Roberto; Schlüter, S.; Orús Pérez, Raul (The Institute of Navigation, 2014)
    Conference report
    Restricted access - author's decision
    This work introduces a novel ionospheric activity indicator useful for identifying disturbed periods affecting performance for GNSS users, at regional level. This indicator is based in the “Along Arc TEC Rate (AATR) and ...
