      Un algoritmo para la detección automática de falsetas de guitarra flamenca  [Final Degree Work]

      Advani Aguilar, Javier Ivar (2016)
      La terminología acuñada en el ámbito de la guitarra flamenca es pobre y en ocasiones algo ambigua, lo que genera gran controversia al estudiarla o interactuar con otros músicos. Así, términos como falseta, melodía ...

      An algorithm that constructs irreducible triangulations of once-punctured surfaces  [Presentation]

      Chávez de Diego, María José; Lawrecenko, Serge; Portillo Fernández, José Ramón; Villar Liñán, María Trinidad (2013)
      A triangulation of a surface is irreducible if there is no edge whose contraction produces another triangulation of the surface. In this work we propose an algorithm that constructs the set of irreducible triangulations ...

      Computing the stretch of an embedded graph  [Presentation]

      Cabello Justo, Sergio; Chimani, Markus; Hliněný, Petr (2013)
      Let G be a graph embedded in an orientable surface Σ, possibly with edge weights, and denote by len(γ) the length (the number of edges or the sum of the edge weights) of a cycle γ in G. The stretch of a graph embedded on ...

      Continuous surveillance of points by rotating floodlights  [Presentation]

      Bereg, Sergey; Díaz Báñez, José Miguel; Fort i Masdevall, Marta; Lopez, Mario A.; Pérez Lantero, Pablo; Urrutia Galicia, Jorge (2013)
      Let P and F be sets of n ≥ 2 and m ≥ 2 points in the plane, respectively, so that P∪F is in general position. We study the problem of finding the minimum angle α ∈ [2π/m, 2π] such that one can install at each point of F a ...

      Covering point sets with two disjoint disks or squares  [Article]

      Cabello, Sergio; Díaz Báñez, José Miguel; Seara Ojea, Carlos; Sellarés, J. Antoni; Urrutia, Jorge; Ventura Molina, Inmaculada (Elsevier, 2007)
      We study the following problem: Given a set of red points and a set of blue points on the plane, find two unit disks CR and CB with disjoint interiors such that the number of red points covered by CR plus the number of ...

      Distance domination, guarding and vertex cover for maximal outerplanar graphs  [Presentation]

      Canales Cano, Santiago; Hernández Peñalver, Gregorio; Oliveira Martins, Ana Mafalda de; Matos. Inês (2013)
      In this paper we de ne a distance guarding concept on plane graphs and associate this concept with distance domination and distance vertex cover concepts on triangulation graphs. Furthermore, for any n-vertex maximal ...

      Drawing the double circle on a grid of minimum size  [Presentation]

      Bereg, Sergey; Fabila Monroy, Ruy; Flores Peñaloza, David; Lopez, Mario A.; Pérez Lantero, Pablo (2013)
      In 1926, Jarník introduced the problem of drawing a convex n-gon with vertices having integer coordinates. He constructed such a drawing in the grid [1, c ·n 3/2]2 for some constant c > 0, and showed that this grid size ...

      Empty convex polytopes in random point sets  [Presentation]

      Balogh, József; González Aguilar, Hernán; Salazar Anaya, Gelasio (2013)
      Given a set P of points in Rd, a convex hole (alternatively, empty convex polytope) of P is a convex polytope with vertices in P, containing no points of P in its interior. Let R be a bounded convex region in Rd. We show ...

      Equipartitioning triangles  [Presentation]

      Ramos Alonso, Pedro Antonio; Steiger, William (2013)
      An intriguing conjecture of Nandakumar and Ramana Rao is that for every convex body K ⊆ R2, and for any positive integer n, K can be expressed as the union of n convex sets with disjoint interiors and each having the same ...

      Un estudio de identificación por tarareo para cante flamenco  [Final Degree Work]

      Serna García, Paula (2019)
      El flamenco como entidad musical tiene su base en la voz cantada, llamada “cante” en el argot flamenco, donde predomina una ornamentación barroca que suele ser improvisada. Esto provoca una serie de retos tecnológicos a ...

      Finding a widest empty 1-corner corridor  [Presentation]

      Díaz Báñez, José Miguel; López, Mario A.; Sellarès Chiva, Joan Antoni (2004)
      Given a set of n points in the plane, we consider the problem of computing a widest empty 1-corner corridor. We star giving a characterization of the 1-corner corridors that we call locally widest. Our approach to finding ...

      Fitting a two-joint orthogonal chain to a point set  [Article]

      Díaz Báñez, José Miguel; Amaro López, M. A.; Mora, M.; Seara Ojea, Carlos; Ventura Molina, Inmaculada (Elsevier, 2010)
      We study the problem of fitting a two-joint orthogonal polygonal chain to a set S of n points in the plane, where the objective function is to minimize the maximum orthogonal distance from S to the chain. We show that ...
