    Encouraging the use of active-learning methodologies, both inside and outside the classroom by means of planned activities, is a key factor in effective learning, as well as being essential for students to achieve the goals ...
  • Transición de la docencia presencial a la no presencial en la UPC durante la pandemia del COVID-19 

    García Planas, María Isabel; Taberna Torres, Judit (2021)
    Article
    Open Access
    Ante el inesperado estado de alarma decretado con motivo de la pandemia producida por el Covid-19, las universidades españolas se han visto obligadas a adaptar la docencia a esta situación, utilizando como medio principal ...
  • State canonical form for a class of uncontrollable linear systems 

    Compta Creus, Albert; Ferrer Llop, Josep; Peña Carrera, Marta (Taylor & Francis, 2019-10-16)
    Article
    Restricted access - publisher's policy
    We tackle the obtaining of canonical forms for classifying linear control systems with regard to changes in the state variables. Although it was solved in the 1980s for controllable systems, it is still an open problem for ...
  • Flipped learning and threshold concepts in the Turbomachinery section of Fluid Engineering course 

    Gámez Montero, Pedro Javier; Peña Carrera, Marta; Olmedo Torre, Noelia (2020-06-09)
    Article
    Restricted access - publisher's policy
    This paper outlines a practical intervention aiming to collect the effects of introducing flexible learning in engineering higher education. The work dis- cusses the implementation of the flipped classroom method and the ...
  • Codimension-3 bifurcation for continuous saddle bimodal linear dynamical systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (2018-02-01)
    Article
    Open Access
    We continue the study of the structural stability and the bifurcations of planar continuous bimodal linear dynamical systems (that is, systems consisting of two linear dynamics acting on each side of a straight line, ...
  • The bundle of simultaneously diagonalizable n-tuples of matrices 

    García Planas, María Isabel (WSEAS Press, 2020-04-27)
    Article
    Open Access
    In this paper, a review of the simultaneous diagonalization of n-tuples of matrices for its applications in sciences is presented. For example, in quantum mechanics, position and momentum operators do not have a shared base ...
  • Differentiable families of traceless matrix triples 

    García Planas, María Isabel; Klymchuk, Tetiana (springer-Verlag, 2019-12-06)
    Article
    Open Access
    Analysis of spectra of families of sets of matrices verifying certain properties is not simple because phenomena as singularities and bifurcations appear. An excellent tool for the analysis can be making use of versal ...
  • On simultaneously and approximately simultaneously diagonalizable m-tuples of matrices 

    García Planas, María Isabel (Fundamental Journal of Mathematics and Applications, 2019)
    Article
    Open Access
    In this paper, the problem of simultaneous diagonalization of m-tuples of n-order square complex matrices, is analyzed and some necessary and some necessary and sufficient conditions for this property to be fulfilled are ...
  • Evaluación del aprendizaje en los alumnos con discalculia 

    García Planas, María Isabel; García-Camba Vives, María Victoria (2019)
    Article
    Open Access
    La discalculia es un trastorno del neurodesarrollo que afecta,a quien lo padece,a sucapacidad para el cálculo, interfiriendo ensurendimiento académico,su nivel de inclusión social, su acceso al mundo laboral, y en especial ...
  • Structural stability of pairs of matrices under contragredient equivalence 

    García Planas, María Isabel; Klymchuk, Tetiana (2019)
    Article
    Open Access
    A complex matrix pencil A-¿B is called structurally stable if there exists its neighborhood in which all pencils are strictly equivalent to this pencil. We describe all complex matrix pencils that are structurally stable. ...
  • On the observability of multiagent neural networks 

    García Planas, María Isabel (WSEAS Press, 2019)
    Article
    Open Access
    We obtain a characterization of observability for a class of linear systems which appear in multiagentneural networks research. Due to the connection between mathematical concept of control dynamical systemsand cognitive ...
  • D-stratification and hierarchy graphs of the space of order 2 and 3 matrix pencils 

    García Planas, María Isabel; Magret Planas, Maria dels Dolors (Universal Journal of Mathematics and Applications, 2019)
    Article
    Open Access
    Small changes in the entries of a matrix pencil may lead to important changes in its Kronecker normal form. Studies about the effect of small perturbations have been made when considering the stratification associated with ...
