  • Characterizing path-like trees from linear configurations 

    López Masip, Susana Clara (2017)
    Comunicació de congrés
    Accés obert
    Assume that we embed the path Pn as a subgraph of a 2-dimensional grid, namely, Pk¿Pl. Given such an embedding, we consider the ordered set of subpaths L1, L2,...,Lm which are maximal straight segments in the embedding, ...
  • Characterizing identifying codes through the spectrum of a graph or digraph 

    Balbuena Martínez, Maria Camino Teófila; Dalfó Simó, Cristina; Martínez Barona, Berenice (2017)

  • Locating-dominating partitions in graphs 

    Pelayo Melero, Ignacio Manuel; Hernando Martín, María del Carmen; Mora Giné, Mercè (2016)
    Text en actes de congrés
    Accés obert
    Let G = (V, E) be a connected graph of order n. Let ¿ = {S1, . . . , Sk} be a partition of V . Let r(u|¿) denote the vector of distances between a vertex v ¿ V and the elements of ¿, that is, r(v, ¿) = (d(v, S1), . . . ...
  • On the spectra of Markov matrices for weighted Sierpinski graphs 

    Comellas Padró, Francesc de Paula; Xie, Pinchen; Zhang, Zhongzhi (2016)
    Text en actes de congrés
    Accés obert
    Relevant information from networked systems can be obtained by analyzing the spectra of matrices associated to their graph representations. In particular, the eigenvalues and eigenvectors of the Markov matrix and related ...
  • Online graph coloring with advice and randomized adversary 

    Muñoz López, Francisco Javier (Springer, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We generalize the model of online computation with three players (algorithm, adversary and an oracle called advisor) by strength- ening the power of the adversary by randomization. In our generalized model, the advisor ...
  • Genera Esfera: Interacting with a trackball mapped onto a sphere to explore generative visual worlds 

    Barrière Figueroa, Eulalia; Carreras, Anna (2016)
    Text en actes de congrés
    Accés obert
    Genera Esfera is an interactive installation that allows the audience to interact and easily become a VJ (visual DJ) in a world of generative visuals. It is an animated and generative graphic environment with a music ...
  • A geometric approach to dense Cayley digraphs of finite Abelian groups 

    Aguiló Gost, Francisco de Asis L.; Fiol Mora, Miquel Àngel; Pérez Mansilla, Sonia (Elsevier, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We give a method for constructing infinite families of dense (or eventually likely dense) Cayley digraphs of finite Abelian groups. The diameter of the digraphs is obtained by means of the related {\em minimum distance ...
  • Digraphs with walks of equal length between vertices 

    Fiol Mora, Miquel Àngel; Alegre, Ignasi; Andrés Yebra, José Luís; Fàbrega Canudas, José (1984)

  • Confección y gestión automática de exámenes tipo test 

    Cañadas Lorenzo, Juan Carlos; Diego Vives, José Antonio; Pelayo Melero, Ignacio Manuel (Universidad de Cádiz, 2016)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    El presente trabajo describe la implementación de una aplicación informática como recurso docente, diseñada como plataforma para la elaboración, utilización y corrección de controles formativos y exámenes de evaluación. ...
  • Counting configuration–free sets in groups 

    Rué Perna, Juan José; Serra Albó, Oriol; Vena Cros, Lluís (2015)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We present a unified framework to asymptotically count the number of sets, with a given cardinality, free of certain configurations. This is done by combining the hypergraph containers methodology joint with arithmetic ...
  • Lissajous curves: an experiment in creative coding 

    Barrière Figueroa, Eulalia (2015)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Do you want to become a creative coder for a day? When artists use a computer to make art, they often experience the need of improving their mathematical skills. On the other hand, students with technical skills are less ...
