Tracking the evolution of research in waste recycling science (WRS) can be valuable for environmental agencies, as well as for recycling businesses. Maps of science are visual, easily readable representations of the cognitive structure of a branch of science, a particular area of research or the global spectrum of scientific production. They are generally built upon evidence collected from reliable sources of information, such as patent and scientific publication databases. This study uses the methodology developed by Rafols et al. (2010) to make a “double overlay map” of WRS upon a basemap reflecting the cognitive structure of all journal-published science, for the years 2005 and 2010. The analysis has taken into account the cognitive areas where WRS articles are published and the areas from where it takes its intellectual nourishing, paying special attention to the growing trends of the key areas. Interpretation of results lead to the conclusion that extraction of energy from waste will probably be an important research topic in the future, along with developments in general chemistry and chemical engineering oriented to the recovery of valuable materials from waste. Agricultural and material sciences, together with the combined economics, politics and geography field, are areas with which WRS shows a relevant and ever increasing cognitive relationship.

The present thesis is focuses on the problem of Simultaneous Localisation and Mapping (SLAM) using only visual data (VSLAM). This means to concurrently estimate the position of a moving camera and to create a consistent map of the environment. Since implementing a whole VSLAM system is out of the scope of a degree thesis, the main aim is to improve an existing visual SLAM system by complementing the commonly used point features with straight line primitives. This enables more accurate localization in environments with few feature points, like corridors. As a foundation for the project, ScaViSLAM by Strasdat et al. is used, which is a state-of-the-art real-time visual SLAM framework. Since it currently only supports Stereo and RGB-D systems, implementing a Monocular approach will be researched as well as an integration of it as a ROS package in order to deploy it on a mobile robot. For the experimental results, the Care-O-bot service robot developed by Fraunhofer IPA will be used.

La aplicaci�n de campos geomagn�ticos con la polaridad cambiante promueve la plasticidad de la corteza visual de animales privados visualmente mediante la cr�a en oscuridad, o bien a trav�s de la sutura palpebral de un ojo.Esto es debido a que la estimulaci�n magn�tica produce la down-regulaci�n de la expresi�n de los microRNAs let-7b*, miR-330, miR-338* y miR-376c en la corteza visual de animales sometidos a la cr�a en oscuridad, as� como de animales sujetos a sutura palpebral de un ojo. Como consecuencia de la down-regulaci�n de la expresi�n de los microRNAs citados anteriormente, se ven incrementados los niveles de expresi�n de sus correspondientes mol�culas diana, Conexina 26 para el caso de let-7b*, Tenascina R en el caso de miR-330, Contactina 4 para el caso de miR-338* y Matriz metalopeptidasa 9 y �-sinucle�na, ambas mol�culas diana de miR-376c. El aumento de expresi�n de estas mol�culas diana a nivel de RNA mensajero, as� como a nivel de prote�na en la corteza visual promueve la capacidad pl�stica de la corteza visual, ya que estas mol�culas diana se encuentran implicadas en procesos de crecimiento/elongaci�n de las neuritas y en la regulaci�n de la morfolog�a de las espinas dendr�ticas.

El presente trabajo constó de una revisión bibliográfica sobre el esquí alpino adaptado para personas con discapacidad física, sensorial visual e intelectual. En él se describieron las diferentes discapacidades nombradas anteriormente y se recogió la historia del deporte adaptado en general y del esquí alpino adaptado en particular, así como los beneficios psicológicos y psicomotores que aporta en cada una de las tres discapacidades. También se describieron los tipos de material adaptado necesario para su práctica según las discapacidades del deportista; la metodología de enseñanza-aprendizaje y la técnica, desde su evolución hasta las nuevas tendencias metodológicas; el reglamento especial y los factores de riesgo que existen en la competición y las lesiones más frecuentes, analizando los tipos, causas, mecanismo y prevención.

Recent player tracking technology provides new information about basketball game performance. The aim of this study was to (i) compare the game performances of all-star and non all-star basketball players from the National Basketball Association (NBA), and (ii) describe the different basketball game performance profiles based on the different game roles. Archival data were obtained from all 2013-2014 regular season games (n = 1230). The variables analyzed included the points per game, minutes played and the game actions recorded by the player tracking system. To accomplish the first aim, the performance per minute of play was analyzed using a descriptive discriminant analysis to identify which variables best predict the all-star and non all-star playing categories. The all-star players showed slower velocities in defense and performed better in elbow touches, defensive rebounds, close touches, close points and pull-up points, possibly due to optimized attention processes that are key for perceiving the required appropriate environmental information. The second aim was addressed using a k-means cluster analysis, with the aim of creating maximal different performance profile groupings. Afterwards, a descriptive discriminant analysis identified which variables best predict the different playing clusters. The results identified different playing profile of performers, particularly related to the game roles of scoring, passing, defensive and all-round game behavior. Coaching staffs may apply this information to different players, while accounting for individual differences and functional variability, to optimize practice planning and, consequently, the game performances of individuals and teams.
