    ABSTRACT The use of original texts from History of Mathematics is a way to introduce the sources on which mathematical knowledge is based into the classroom. Choosing historical texts carefully can help students to develop ...

  • Detection of replay attacks in cyber-physical systems using a frequency-based signature 

    Sánchez Corrales, Helem Sabina; Rotondo, Damiano; Escobet Canal, Teresa; Puig Cayuela, Vicenç; Saludes Closa, Jordi; Quevedo Casín, Joseba Jokin (2019-03-01)
    Article
    Open Access
    This paper proposes a frequency-based approach for the detection of replay attacks affecting cyber-physical systems (CPS). In particular, the method employs a sinusoidal signal with a time-varying frequency (authentication ...

  • A new lower bound on the maximum number of plane graphs using production matrices 

    Huemer, Clemens; Pilz, Alexander; Silveira, Rodrigo Ignacio (2019-11-01)
    Article
    Restricted access - publisher's policy
    We use the concept of production matrices to show that there exist sets of n points in the plane that admit ¿(42.11n ) crossing-free geometric graphs. This improves the previously best known bound of ¿(41.18n ) by Aichholzer ...
