• openAccess   Transitivity in Fuzzy Hyperspaces 

      Jardón, Daniel; Sánchez, Iván; Sanchis, Manuel MDPI (2020)
      Given a metric space (X, d), we deal with a classical problem in the theory of hyperspaces: how some important dynamical properties (namely, weakly mixing, transitivity and point-transitivity) between a discrete dynamical ...

      Gregori, Pablo; Martínez, Vicente UNED (2018)
      Los profesores de matemáticas, frecuentemente, encuentran problemas en la representación de símbolos para comunicarse de manera virtual con sus estudiantes. En este sentido y con el objetivo de facilitar la comunicación ...
    • openAccess   Unsupervised classification of children’s bodies using currents 

      Barahona, S.; Gual-Arnau, Ximo; Ibáñez Gual, Maria Victoria; Simó, Amelia Springer Verlag (2018-06)
      Object classification according to their shape and size is of key importance in many scientific fields. This work focuses on the case where the size and shape of an object is characterized by a current. A current is a ...

      Galindo, Carlos; Gregori, Pablo; Martínez, Vicente Taylor & Francis (2019-09-11)
      In this paper we present a pilot study to improve the learning process on distance learning Engineering master's degrees. We propose an activity where the students individually produce a video in which they explain the ...
    • openAccess   Well-posedness for degenerate third order equations with delay and applications to inverse problems 

      Conejero, J. Alberto; Lizama, Carlos; murillo arcila, marina; Seoane Sepúlveda, Juan Springer (2018-10)
      In this paper, we study well-posedness for the following third-order in time equation with delay (0.1)α(Mu′)′′(t)+(Nu′)′(t)=βAu(t)+γBu′(t)+Gu′t+Fut+f(t),t∈[0,2π] where α, β, γ are real numbers, A and B are linear operators ...

      Martínez Usó, María José; Marco, Francisco J. Cambridge University Press (2019-12)
      In the context of the European Middle Ages as the period roughly covering from the 5th to the 15th centuries, the astronomical records are rarery found in scientific treatises. At least, not until the 15th century. A few ...
