    • Capturing points with a rotating polygon (and a 3D extension) 

      Alegría Galicia, Carlos; Orden, David; Palios, Leonidas; Seara Ojea, Carlos; Urrutia Galicia, Jorge (2019-04)
      Article
      Accés obert
      We study the problem of rotating a simple polygon to contain the maximum number of elements from a given point set in the plane. We consider variations of this problem where the rotation center is a given point or lies on ...

    • Natural generalizations of threshold secret sharing 

      Farràs Ventura, Oriol; Padró Laimon, Carles; Xing, Chaoping; Yang, An (2014-01-14)
      Article
      Accés obert
      We present new families of access structures that, similarly to the multilevel and compartmented access structures introduced in previous works, are natural generalizations of threshold secret sharing. Namely, they admit ...

    • Zero and coefficient inequalities for hyperbolic polynomials 

      Rubió Massegú, Josep; Díaz Barrero, José Luis; Rubió Díaz, Pedro (2006-03)
      Article
      Accés obert
      In this paper using classical inequalities and Cardan-Viète formulae some inequalities involving zeroes and coefficients of hyperbolic polynomials are given. Furthermore, considering real polynomials whose zeros lie in ...
