  • Region-based approximation algorithms for visibility between imprecise locations 

    Buchin, Kevin; Kostitsyna, Irina; Löffler, Maarten; Silveira, Rodrigo Ignacio (2015)
    Conference report

    In this paper we present new geometric algorithms for approximating the visibility between two imprecise locations amidst a set of obstacles, where the imprecise locations are modeled by continuous probability distributions. ...
  • Determination of criteria for the exploration and for obtaining indicators in evolutional analysis of degradation in urban facades 

    Gibert Armengol, Vicente; Serrat Piè, Carles; Casas Rius, Joan Ramon (2014)
    Conference report
    Open Access
    The interest of this research is motivated by the huge constructive development in the building sector, which has led to an enormous volume of buildings worldwide over the last decades. This fact, as well as poor management ...
  • Fault tolerant control for wind turbine pitch actuators 

    Rodellar Benedé, José; Acho Zuppa, Leonardo; Tutivén Gálvez, Christian; Vidal Seguí, Yolanda (2015)
    Conference report
    Open Access
    This paper develops a fault detection and isolation (FDI) and active fault tolerant control (FTC) of pitch actuators in wind turbines (WTs). This is accomplished combining a disturbance compensator with a controller, both ...
  • Inversa de matrices circulantes con tres parámetros 

    Mitjana Riera, Margarida (2015)
    Conference report
    Open Access
    Utilizando técnicas relacionadas con la resolución de problemas de contorno para ecuaciones en diferencias de segundo orden, se dan condiciones necesarias y suficientes cientes para la invertibilidad de matrices circulantes ...
  • Passivity-based control of multi-terminal HVDC systems under control saturation constraints 

    Dòria Cerezo, Arnau; Olm Miras, Josep Maria; Scherpen, Jacquelien M.A. (2015)
    Conference report

    This paper proposes a decentralized, passivity-based cont rol design for power stations in a multi-terminal High Voltage Direct Current transmissi on system. The control algorithm is shown to asymptotically stabilize the ...
  • Resistencias efectivas en redes subdivisión 

    Monsó Burgués, Enrique P.J. (Editorial Universidad de Almería, 2015)
    Conference report
    Restricted access - publisher's policy
    En este trabajo se presenta una forma de resolver problemas de Poisson en redes subdivididas. A partir de una red dada y de la solución de un problema de Poisson concreto en ésta, se establecen las condiciones necesarias ...
  • Teoría de Floquet para ecuaciones en diferencias lineales de segundo orden y homogéas 

    Jiménez Jiménez, M. Jose (Editorial Universidad de Almería, 2015)
    Conference lecture
    Restricted access - publisher's policy
    En este trabajo aportamos una versión del teorema de Floquet aplicable a cualquier ecuación en diferencias lineal de segundo orden con coeficientes casi–periódicos. Obtenemos que este tipo de ecuaciones son equivalentes ...
  • Hybrid cell centred/vertex model for cellular nanolayers 

    Mosaffa, Payman; Asadipour, Nina; Millán, Daniel; Rodríguez Ferran, Antonio; Muñoz Romero, José (2015)
    Conference report
    Open Access
    Macroscopic deformations in embryonic soft tissues are due to the intra-cellular remodelling and cell intercalation. We here present a computational approach that can handle the two types of deformations, and also take ...
  • Códigos monomiales vistos como subespacios vectoriales invariantes 

    García Planas, María Isabel; Magret Planas, Maria dels Dolors; Um, Laurence Emilie (2015)
    Conference report
    Open Access
    Es bien sabido que los códigos cíclicos son muy útiles en aplicaciones en general y a los criptosistemas en particular, ya que no resultan costosos desde un punto de vista computacional, además estos códigos alcanzan la ...
  • On the stability in probability of Markov jump systems with quadratic terms 

    Vargas, Alessandro N.; Pujol Vázquez, Gisela; Acho Zuppa, Leonardo; do Val, Joao B.R. (2015)
    Conference lecture
    Restricted access - publisher's policy
    The note presents conditions to assure the stability in probability for a class of continuoustime quadratic Markov jump systems. From the viewpoint of the state-space evolution, the system has two parts: (i) a linear term, ...
