  • The group inverse of some circulant matrices 

    Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José (2019)
    Conference report
    Open Access
    We present here necessary and sufficient conditions for the invertibility of some circulant matrices that depend on three parameters and moreover, we explicitly compute the inverse. Our study also encompasses a wide class ...
  • An on-line statistic algorithm to fault detection in controlled systems: a study case 

    Ponce de León Puig, Nubia Ilia; Acho Zuppa, Leonardo; Rodellar Benedé, José (2019)
    Conference report
    Restricted access - publisher's policy
    The main objective of this paper is to propose an on-line statistic algorithm for fault detection in non-linear dynamic systems based on data analysis. This discipline is a branch of the statistical science and it allows ...
  • The use of the dynamic vibration absorber for energy harvesting 

    Acho Zuppa, Leonardo; Awrejcewicz, Jan; Losyeva, Nataliya; Puzyrov, Volodymyr; Savchenko, Nina (2019)
    Conference report
    Restricted access - publisher's policy
    Vibration energy is abundantly present in many natural and arti cial systems and can be assembled by various mechanisms, mainly using piezoelectric and electromagnetic means. In the present article, the electromechanical system ...
  • 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 ...
  • On identifying codes in line digraphs 

    Dalfó Simó, Cristina; Balbuena Martínez, Maria Camino Teófila; Martínez Barona, Berenice (2019)

  • The expression of air quality in urban areas: going further on a Compositional Data Analysis approach 

    Gibergans Bàguena, José; Hervada Sala, Carme; Jarauta Bragulat, Eusebio (Universitat Politècnica de Catalunya (UPC), 2019)
    Conference report
    Open Access
    The quality of atmospheric air in large cities is a matter of great importance because of its impact on the environment and on the health of the population. Recently, measures restricting access of private vehicles to the ...
  • An iterative linear matrix inequality controller-design strategy for H-infinity structural vibration control 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Reza Karimi, Hamid (CRC Press/Balkema, 2019)
    Conference report
    Restricted access - publisher's policy
    In this paper, we present a novel Iterative Linear Inequality (ILMI) strategy for controller design that makes it possible to compute suboptimal H-infinity static output-feedback (SOF) controllers with high-performance ...
  • Development and enhancement of inclusion services at higher education level 

    Josa i Culleré, Irene; Farré Tost, Carles; Gálvez Carrillo, Maria Immaculada; Ferrer Balas, Dídac; Vilalta Porta, Montserrat; Montero Mercadé, Lídia (International Association of Technology, Education and Development (IATED), 2019)
    Conference report
    Open Access
    Everyone is unique in their own way and it is necessary to embrace this diversity and make positive use of it. At all levels of education, differences between students can provide a good learning opportunity since every ...
  • Detection and classification of structural changes using t-distributed stochastic neighbor embedding 

    Agis Cherta, David; Pozo Montero, Francesc (2019)
    Conference report
    Open Access
    This work states a structural health monitoring strategy for detection and classification of structural changes. The proposed approach is based on the so-called t-distributed stochastic neighbor embedding (t-SNE), a ...
  • Eigenvalues with respect to a weight for discrete elliptic boundary value problems 

    Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (2019)
    Conference report

  • Generalizing the bottleneck matrix 

    Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida; Monsó Burgués, Enrique P.J. (2019)
    Conference report
    Open Access
    Given the Laplacian matrix associated to a weighted graph and given x a single vertex of it, the bottleneck matrix (related to x) is the inverse matrix of the sub matrix of the Laplacian obtained by eliminating the row ...
