    Este trabajo es una investigación y recopilación de información de la empresa The Walt Disney Company. El objetivo del trabajo es establecer cómo ha llegado a tener tanto poder de mercado y cómo ha pasado a ser una empresa multimedia dedicada a la sinergia de sus contenidos. Para ello, veremos diferentes puntos que han servido para la construcción de la empresa, tal y como se la conoce ahora: sus orígenes y su evolución, la construcción y explotación de su marca, la adquisición de otras empresas o la introducción en otros negocios conexos. Estos puntos nos ayudaran a entender su funcionamiento y el posible futuro de la compañía.Universidad de Sevilla. Grado en Comunicación Audiovisua

    Searching for partial Hadamard matrices

    Get PDF
    Three algorithms looking for pretty large partial Hadamard ma- trices are described. Here “large” means that hopefully about a third of a Hadamard matrix (which is the best asymptotic result known so far, [8]) is achieved. The first one performs some kind of local exhaustive search, and consequently is expensive from the time consuming point of view. The second one comes from the adaptation of the best genetic algorithm known so far searching for cliques in a graph, due to Singh and Gupta [21]. The last one consists in another heuristic search, which prioritizes the required processing time better than the final size of the partial Hadamard matrix to be obtained. In all cases, the key idea is characterizing the adjacency properties of vertices in a particular subgraph Gt of Ito’s Hadamard Graph (4t) [18], since cliques of order m in Gt can be seen as (m + 3) × 4t partial Hadamard matrices.Ministerio de Ciencia e Innovación MTM2008-06578Junta de Andalucía FQM-016Junta de Andalucía P07-FQM-0298

    ACS Searching for D4t-Hadamard Matrices

    An Ant Colony System (ACS) looking for cocyclic Hadamard matrices over dihedral groups D4t is described. The underlying weighted graph consists of the rooted trees described in [1], whose vertices are certain subsets of coboundaries. A branch of these trees defines a D4t- Hadamard matrix if and only if two conditions hold: (i) Ii = i − 1 and, (ii) ci = t, for every 2 ≤ i ≤ t, where Ii and ci denote the number of ipaths and i-intersections (see [3] for details) related to the coboundaries defining the branch. The pheromone and heuristic values of our ACS are defined in such a way that condition (i) is always satisfied, and condition (ii) is closely to be satisfied.Ministerio de Ciencia e Innovación MTM2008-06578Junta de Andalucía FQM–296Junta de Andalucía P07-FQM-0298

    Seed Germination Behaviour in Sideritis from Different Iberian Habitats

    [EN] The germination behaviour of two Iberian endemic labiates, Sideritis pungens and S. chamaedryfolia selected from different habitats, ranging from very humid to semi-arid, was studied under controlled experimental conditions. A factorial experiment, combining different temperature regimes (10 degrees, 15 degrees, 20 degrees, 25 degrees or 30 degrees C), photoperiod (total darkness and 12 h light/12 h darkness) and different pre-treatments (freezing, dry-heat, hot-water), was designed to analyze seed germination patterns and dormancy processes. The. results obtained are in agreement with the ecology of the two species. Seeds are not dormant after collection and maintain high viability when preserved by standard seed bank conservation protocols. It was found out that optimal temperature for germination is 20 degrees C for both species. Light seems to play a key role in the germination of genus Sideritis, particularly for S. chamaedryfolia, significantly inhibited by light as other psammophilous plants. Temperature and light arc relevant environmental indicators, but it was found out that the germination response to these factors in the studied species is correlated with a different environmental factor, namely the availability of water resources in their habitats, which is generally a major constraint factor for seed germination in Mediterranean areas. The results indicate that germination limitations are not so much related to taxonomic position, but rather adaptations to water restrictions.This research were cofunded by the Generalitat Valenciana (Conselleria de Territory i Habitatge) and the European Commission, through the Projects LIFE Conservacion de Habitats Prioritarios (LIFE 99 This research were co-funded by the Generalitat Valenciana (Conselleria de Territory i Habitatge) and the European Commission, through the Projects LIFE Conservacion de Habitats Prioritarios (LIFE 99 NAT/E/006417) and Gestión y Puesta en Valor de Tres Hábitats de Alta Montaña (LIFE 03 NAT/E/000064).
