  1. Efecto de las hormonas vegetales en la formación de los óvulos de tomate y sus interacciones

    LÓPEZ MARTÍNEZ, JAVIER
    [EN] In this paper we want to see the role of auxin (AUXs), bras sino steroids (BRs) and gibberellins (GAs) hormones in th e development of the tomato ovule ( Solanum lyc opersicum L. ). For this purpose, mutant lines with alterations in the synthesis or signaling of these hormones were used in the genetic background of the tomato cultivar Micro - Tom (MT). The effect of these mutations on the structure and morphology of ovule during their development prior to flower anthesis , was studied by confocal microscopy. In addition, auxin localization studies were carried out using reporter line (DR5: GUS ) and gibberellins localization by the reporter line ( p GA20ox1: GUS ) . The results co nfirm that the bras s inosteroids regulate positively the...

  2. Algoritmos para la generación de datos subrogados: análisis, implementación y paralelización

    Belda Valls, Jordi
    [EN] Abstract Surrogate methods are very useful in nonlinearities detection application and supervised detection or classification where there aren’t available sufficient data. In both cases it’s needed optimize runtime methods so, in the case of detecting nonli- nearities can be performed virtually in real time and in the case of generating data they can be large. The present work analyzes the major algorithms and design an implementation op- timized of the different versions of them.

  8. Interacción mediante gestos con Leap Motion

    TIPANTUÑA TOAPANTA, GIOVANNY JAVIER
    [EN] The interaction using gestures or gesture interaction allows interaction with applications through user s gestures. Since the appearance of Kinect numerous applications have been developed incorporating such interaction. Kinect 2 allows simultaneous detection of up to 6 people, with 25 points on the body, and the detection of the user's hands. Kinect is designed for tracking people and detection of the position of the limbs as a whole, but Kinect is not able to accurately identify the fingers of one hand. Leap Motion, which appeared later, is a specific device for accurate detection of hands and finger movements. Therefore,...

  9. Papel defensivo de los compuestos volátiles de hoja verde en plantas de tomate frente a una infección bacteriana

    OZÁEZ MARTÍNEZ, MIGUEL
    En respuesta a las señales de estrés, las plantas sintetizan proteínas de defensa y compuestos químicos de diversa naturaleza. Estos compuestos pueden ejercer funciones defensivas directas, esto es, actuando como antioxidantes, antibacterianos o antifúngicos, o actuar como metabolitos defensivos indirectos, señalizando la respuesta defensiva. Algunos compuestos volátiles (VOCs) pertenecen a este grupo de compuestos defensivos (Niinemets et al., 2013). En el laboratorio donde realizaré mi TFM, se llevó a cabo un análisis metabolómico mediante GC-MS de la interacción tomate Rio Grande portador del gen Pto y la bacteria Pseudomonas syringae portadora o no del gen AvrPto.

  10. Aprendizaje por refuerzo mediante métodos de búsqueda de política en sistemas electromecánicos

    Pastor Alcaraz, José Manuel
    [EN] The aim of this master thesis is to study the state of art of reinforment learning, particularly those based on policy search methods and to apply such techniques to a 3DOFs inverted pendulum mechanism. The controller must learn an "optimal control" policy that maximizes the reward (as a cost function) without using any model. The controller will learn on-policy or off-policy a closed loop feedback control law to set the pendulum on its marginally stable vertical position. This work is oriented to students who want to extend further work on his/her PhD. thesis in complex robot systems.

    PASCUAL GUZMÁN, ANTÓN
    [EN] Changes in land use and reducing grazing practices in recent years have highlighted problems of sustainability of some livestock systems, with environmental implications. In order to find alternatives to this situation, the LIFE REGEN FARMING project (LIFE12 ENV / ES / 000232), in which this work of master is encompassed, promote the viability of regenerative practices, including the "rotational" grazing or "targeted" due to both its technical-economic and environmental effectiveness. Rotational grazing or directed (D) has advantages such as: increasing forage production and provide better quality forage, allow recovery of plants and control supply, and avoid selecting animals. This more...

  17. Estudio experimental de la adherencia de armaduras pasivas de acero en hormigones reforzados con fibras

    VÁSQUEZ FÉLIX, GEOVANNY RAMÓN
    [EN] Reinforced concrete, as a composite material, requires the transmission of stress from one material to another, this is achieved through bond. Satisfactory performance of the bonding behavior is the most important objective in of reinforced concrete components, as this interface can be presented as the weak point of a concrete member, so that if a bond failure occurs, the structure failure may occur. One of the ways to improve the bond of the steel-concrete interface, incorporating fibers into the concrete matrix, this is due to the confinement provided by the fibers, playing a similar role to that of traditional transverse...

  19. Determinación del valor económico de un impacto ambiental con el enfoque de servicios ecosistémicos aplicando la metodología AMUVAN: Caso implementación de humedales artificiales del Proyecto Life Albufera. Valencia.

    VILLARREAL GUTIÉRREZ, JOHN PAUL
    [EN] Ecosystems and human well-being are linked, decisions on ecosystems are usually conditioned by the economic benefits obtained from the market, sacrificing the benefits for which there is no market. For this reason, it is important to assign a total economic value to an environmental impact that includes all ecosystem services affected, in order to increase the information for decision-makers that affect the natural spaces. This work proposes the attainment of the economic value in the monetary unit of an environmental impact starting from the change of value of the ecosystem services of provisioning in the space; Using the method called AMUVAN (Multicriteria Analytical Valuation Method) that combines...
