  1. Development of a methodology for scientometric analysis. application to study worldwide research on hardware architecture and cybernetics

    Singh, Virender
    El crecimiento de la producción científica en las últimas décadas y su indexación en las bases de datos bibliográficas han impulsado el uso de metodologías cienciométricas y, consecuentemente, la generación de indicadores para medir los resultados de las actividades científicas y tecnológicas. El estudio de la producción científica en un área de investigación es siempre un indicador del progreso de la investigación y la generación de conocimiento. El objetivo principal de esta tesis es desarrollar una metodología que permita llevar a cabo análisis cienciométricos de carácter global, mediante la combinación de diferentes enfoques complementarios, caracterizando de forma integral la investigación...

  3. Knowledge description model for bodies of knowledge in software engineering context

    Quezada Sarmiento, Pablo Alejandro; Garbajosa Sopeña, Juan; Washizaki, Hironori; Enciso Quispe, Liliana Elvira
    Bodies of Knowledge (BOK) contains the relevant knowledge for a discipline. BOK must embody the consensus reached by the community for which this BOK will be of application. This consensus is a prerequisite for the adoption of the BOK by the community. In this paper, we utilize a combinations of Software Engineering Body of Knowledge (SWEBOK), models representation, and design science methodology in order to describe the software engineering knowledge context (SEC). SWEBOK serves as backbone taxonomy, while models representation provides a context of representation. In the process of develop of this paper science design methodology was used to provide...

  4. Fuzzy MCDA for remediation of a uranium tailing

    Pérez-Sánchez, Danyl; Jiménez Martín, Antonio; Mateos Caballero, Alfonso; Dvorzhak, Alla
    The Pridneprovsky Chemical Plant was a largest uranium processing enterprises, producing a huge amount of uranium residues. The Zapadnoe tailings site contains the majority of these residues. We propose a theoretical framework based on Multi-Criteria Decision Analysis and fuzzy logic to analyse different remediation alternatives for the Zapadnoe tailings, in which potentially conflicting economic, radiological, social and environmental objectives are simultaneously taken into account. An objective hierarchy is built that includes all the relevant aspects. Fuzzy rather than precise values are proposed for use to evaluate remediation alternatives against the different criteria and to quantify preferences, such as the weights...

  5. Are some brain injury patients improving more than ohers?

    Siddiqui, Zaigham Faraz; Krempl, Georg; Spiliopoulou, Myra; Peña Sánchez, José María; Paul Lapedriza, Nuria; Maestu Unturbe, Fernando
    Predicting the evolution of individuals is a rather new mining task with applications in medicine. Medical researchers are interested in the progress of a disease and in the evolution of individuals subjected to treatment. We investigate the evolution of patients on the basis of medical tests before and during treatment after brain trauma: we want to understand how similar patients can become to healthy participants. We face two challenges. First, we have less information on healthy participants than on the patients. Second, the values of the medical tests for patients, even after treatment started, remain well-separated from those of healthy...

  6. A Fuzzy approach based on dynamic programming and metaheuristics for selecting safeguards for risk management for information systems

    Vicente Cestero, Eloy; Mateos Caballero, Alfonso; Jiménez Martín, Antonio
    In this paper we focus on the selection of safeguards in a fuzzy risk analysis and management methodology for information systems (IS). Assets are connected by dependency relationships, and a failure of one asset may affect other assets. After computing impact and risk indicators associated with previously identified threats, we identify and apply safeguards to reduce risks in the IS by minimizing the transmission probabilities of failures throughout the asset network. However, as safeguards have associated costs, the aim is to select the safeguards that minimize costs while keeping the risk within acceptable levels. To do this, we propose a...

  7. Análisis de la cadena de valor de la caoba en las cooperativas agroforestales del Valle de Sico-Paulaya e implementación del plan de negocio.

    González Folgueral, José Ignacio
    La extracción de madera de caoba de las zonas remotas del Valle de Sico-Paulaya es un difícil y costoso proceso en el que intervienen muchos y diferentes actores, cada uno con sus propios intereses. La coordinación para realizar este proceso debería repercutir en mejoras para todos los actores y en la creación de unas relaciones de interdependencia. El proceso de extracción de la madera de caoba para exportación se viene realizando desde el año 2000 por alguna de estas cooperativas agroforestales, por lo que se trata de un proceso ya afianzado en el que el mayor problema es la sostenibilidad del...

  8. Temperature Evolution and Light Species Diffusion in Armor and Structural Material for Inertial Fusion Reactor Chambers: a Case for HiPER 4a

    Garoz Gómez, David; Hontoria, R.S.; Alvarez Ruiz, Jesus; Rivera de Mena, Antonio; Gonzalez Arrabal, Raquel; Perlado Martín, José Manuel
    One of the most advance designs for HiPER fusion reactor is a spherical chamber 10 m in diameter based on dry wall concept. In this system, the first wall will have to withstand short energy pulses of 5 to 20 MJ at a repetition rate of 0.5-10 Hz mostly in form of X-rays and charged particles. To avoid melting of the inner surface, the first wall consists on a thin armor attached to the structural material. Thickness (th) and material of each layer have to be chosen to assure the proper functioning of the facility during its planned lifetime.
