  • Computing optimal shortcuts for networks 

    Garijo Royo, Delia; Marquez Pérez, Alberto; Rodríguez, Natalia; Silveira, Rodrigo Ignacio (Elsevier, 2019-11-16)
    Article

    We study augmenting a plane Euclidean network with a segment, called a shortcut, to minimize the largest distance between any two points along the edges of the resulting network. Problems of this type have received ...

  • Exponential stability in type II thermoviscoelasticity with voids 

    Miranville, Alain; Quintanilla de Latorre, Ramón (2020-04)
    Article
    Restricted access - publisher's policy
    In this paper we consider the one-dimensional type II thermoviscoelastic theory with voids. We prove that generically we have exponential stability of the solutions. This is a striking fact if one compares it with the ...

  • A frequency-based approach for the detection and classification of structural changes using t-SNE 

    Agis Cherta, David; Pozo Montero, Francesc (Multidisciplinary Digital Publishing Institute (MDPI), 2019-11-21)
    Article
    Open Access
    This work presents a structural health monitoring (SHM) approach for the detection and classification of structural changes. The proposed strategy is based on t-distributed stochastic neighbor embedding (t-SNE), a nonlinear ...

  • Whiskered parabolic tori in the planar (n+ 1) -body problem 

    Baldomá Barraca, Inmaculada; Fontich Julia, Ernest; Martín de la Torre, Pablo (2019-01-01)
    Article
    Restricted access - publisher's policy
    The planar (n+1)-body problem models the motion of n+1 bodies in the plane under their mutual Newtonian gravitational attraction forces. When n=3, the question about final motions, that is, what are the possible limit ...

  • Numerical experimental validation of a proposed MPPT algorithm with dynamic hysteresis for PV systems 

    Ponce de León Puig, Nubia Ilia; Acho Zuppa, Leonardo; Rodellar Benedé, José (2019-06-28)
    Article
    Open Access
    In the last decades, the renewable energies have had a highly positive effect on the daily life. This due to the necessity of reducing the common fuel energies that have negatively impacted the environment. Among all the ...

  • Sliding mode control of a differential-drive mobile robot following a path 

    Dòria Cerezo, Arnau; Biel Solé, Domingo; Olm Miras, Josep Maria; Repecho del Corral, Víctor (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    This paper presents a control algorithm for a differential-drive robot following a path. The main contributions are: a new control formulation that does not require the robot global position, and a nonlinear controller ...

  • Independent learning as class preparation to foster student-centred learning in first-year engineering students 

    Pejuan Alcobé, Arcadi; Antonijuan Rull, Josefina (2019-11-08)
    Article
    Open Access
    In first-year engineering students, a common teacher-centred, passive learning and deficient secondary educational backgrounds are often observed. However, there is a problematic difference whether the individual background ...

  • On identifying codes in line digraphs 

    Dalfó Simó, Cristina; Balbuena Martínez, Maria Camino Teófila; Martínez Barona, Berenice (2019)
    Conference report
    Open Access

  • Revisión de las técnicas de monitorización del estado de los rodamientos de las palas de los aerogeneradores 

    Sandoval Núñez, Diego Aníbal; Leturiondo, Urko; Pozo Montero, Francesc; Vidal Seguí, Yolanda; Salgado, Óscar (2019-11)
    Article

    El aumento continuo del consumo energético ha sido una necesidad para el desarrollo de la sociedad humana, produciendo la energía necesaria históricamente con combustibles fósiles. El uso de estos combustibles y su ...

  • Condition assessment of building façades based on hazard to people 

    Ruiz Gorrindo, Félix; Aguado de Cea, Antonio; Serrat Piè, Carles; Casas Rius, Joan Ramon (2019-06)
    Article
    Restricted access - publisher's policy
    To make periodic inspections of the buildings is useful to quantify the extent to which deficiencies are severe or not, in order to facilitate decision making and prioritize interventions. In previous works by the authors ...

  • Experimental validation of a continuous-time MCSI algorithm with bounded adaptive gains 

    Montanaro, Umberto; Costa Castelló, Ramon; Olm Miras, Josep Maria; Larco Barros, Ciro (2019-08-01)
    Article
    Restricted access - publisher's policy
    Model reference adaptive control algorithms with minimal controller synthesis have proven to be an effective solution to tame the behaviour of linear systems subject to unknown or time-varying parameters, unmodelled dynamics ...

  • On the linear thermoelasticity with two porosities: numerical aspects 

    Bazarra, Noelia; Fernández, José Ramón; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-10-30)
    Article
    Restricted access - publisher's policy
    In this work we analyze, from the numerical point of view, a dynamic problem involving a thermoelastic rod. Two porosities are considered: the first one is the macro-porosity, connected with the pores of the material, and ...
