  • Secure and efficient anonymization of distributed confidential databases 

    Herranz Sotoca, Javier; Nin Guerrero, Jordi (2014)
    Article
    Restricted access - publisher's policy
    Let us consider the following situation: t entities (e.g., hospitals) hold different databases containing different records for the same type of confidential (e.g., medical) data. They want to deliver a protected version ...
  • Fault diagnosis and fault-tolerant control of wind turbines via a discrete time controller with a disturbance compensator 

    Vidal Seguí, Yolanda; Tutivén Gálvez, Christian; Rodellar Benedé, José; Acho Zuppa, Leonardo (2015-05-12)
    Article
    Open Access
    This paper develops a fault diagnosis (FD) and fault-tolerant control (FTC) of pitch actuators in wind turbines. This is accomplished by combining a disturbance compensator with a controller, both of which are formulated ...
  • AAR-based decomposition algorithm for non-linear convex optimisation 

    Rabiei, Syednima; Muñoz Romero, José (2015)
    Article
    Open Access
    n this paper we present a method for decomposing a class of convex nonlinear programmes which are frequently encountered in engineering plastic analysis. These problems have second-order conic memberships constraints and ...
  • Structural damage detection using principal component analysis and damage indices 

    Tibaduiza Burgos, Diego Alexander; Mujica Delgado, Luis Eduardo; Rodellar Benedé, José; Güemes Gordo, Alfredo (2015-01-08)
    Article
    Open Access
    One of the most important tasks in structural health monitoring corresponds to damage detection. In this task, the existence of damage should be determined. In the literature, several potentially useful techniques for ...
  • Measuring the relevance of factors in the occurrence of events 

    Fragnelli, Vito; Freixas Bosch, Josep; Pons Vallès, Montserrat; Sanmiquel Pera, Lluís (2014-05-09)
    Article
    Restricted access - publisher's policy
    A new way to compare the relevance of the different factors intervening in the occurrences of an event is presented and developed in this paper. The idea behind the method comes from cooperative game theory but the focus ...
  • A discrete-time chaotic oscillator based on the logistic map: A secure communication scheme and a simple experiment using Arduino 

    Acho Zuppa, Leonardo (2015-03-29)
    Article
    Open Access
    This paper presents a modified discrete-time chaotic system obtained from the standard logistic map model. Then, a secure communication system is given and numerical experiments are carry out using the conceived discrete-time ...
  • Success and decisiveness on proper symmetric games 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2013-11-20)
    Article
    Restricted access - publisher's policy
    This paper provides a complete study for the possible rankings of success and decisiveness for individuals in symmetric voting systems, assuming anonymous and independent probability distributions. It is proved that for ...
  • Control difuso para el seguimiento de guiñada del AUV Cormorán 

    González Agudelo, Julián; Gomáriz Castro, Spartacus; Batlle Arnau, Carles (2015-03-31)
    Article

  • Asymetric modelling and control of an electronic throttle 

    Pujol Vázquez, Gisela; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Vargas, Alessandro N. (2015-04-20)
    Article
    Restricted access - publisher's policy
    This paper presents an improved model for an automotive electronic throttle inspired on the behavior observed in real-time experiments. Due to a number of issues, particularly the return-spring, the performance of the ...
  • Set-membership parity space approach for fault detection in linear uncertain dynamic systems 

    Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç; Saludes Closa, Jordi; Fernández Canti, Rosa M. (2014-03-11)
    Article
    Open Access
    In this paper, a set-membership parity space approach for linear uncertain dynamic systems is proposed. First, a set of parity relations derived from the parity space approach is obtained by means of a transformation derived ...
