  11. Comunicación Pública de la Ciencia sobre los Medios Nuevos e Innovadores para Atraer al Público a la Área de Ciencia: Análisis y recomendaciones

    HE, XIAOFAN
    The truth is that not everyone likes science although it is very important for us now. Or we can say that without science, the world will not work as it is now. But for many people, science is an unknown area or it is far away from their life even though their life is actually closely related to science. Then, for them science is not something that is talked normally in everyday life as a football mathch. However, as a student who carries this theme in his master, I'd like to do a project with different cases and methodologies such...

Nowadays, thanks to the advances in science, there are more and more products that increasingly solve the negative effects produced on the cultural property. To this respect, nanoscience is currently an emerging field that offers us...

  13. Metaheurísticas para el diseño de redes de ferrocarril en competencia con medio de transporte alternativo

    RUBIO DEL REY, FERNANDO
    El diseño de redes de ferrocarril en competencia con modos de transporte alternativo (RND por sus siglas en inglés) se puede modelar como un problema de optimización combinatoria sobre un grafo dirigido. El objetivo del RND es diseñar una red de ferrocarril que atraiga al mayor número de pasajeros posible, suponiendo una restricción presupuestaria. Estudios previos han demostrado que este problema es NP-duro. Además de esa justificación teórica, trabajos publicados en la literatura científica han demostrado que los modelos matemáticos para el RND no son aplicables a instancias de este problema de tamaño real. Por todo ello, la investigación sobre...

  17. Modelo matemático de la red de agua potable de la ciudad de Sueca

    GUARINOS FERRER, EFRÉN
    Today the best way to manage a supply network is to have a model that helps us to visualize the network and to make adjustments and tests to improve it. In order to do this, we use programs simulating the real network. In order to be able to make a correct model, real data of the network, such as materials, pipe lengths, dimensions, reservoir location, pumping system information if there is, and orders information as well as their distribution. In the present work, the mathematical model has been elaborated in Epanet, which belongs to the drinking supply water of the city of...

    TAVIRO MORALEDA, EVA MARÍA
    This Master's Tesis has focused on the main objective of investigating the situation of restorer training during the twentieth century. It also intends to explain how this process affected the restorer professionalization and work situation, especially concerning public centers. Restoration in museums in the seventies and eighties of the twentieth century required restorers to have a title that would certify their work, a complicated degree to obtain at that historical moment, due to the lack of studies leading to the achievement of this specific degree. With this, in order to alleviate this situation, a Ministerial Order was created which was...
