    El objetivo principal del presente trabajo es dar a conocer, dentro del marco general del poblamiento prerromano del valle medio del Guadiana, una primera valoración global de los trabajos arqueológicos realizados entre 1986 y 1988 en los recintos ciclópeos de la serena (Badajoz). Dichos asentamientos fueron prospectados en su practica totalidad durante los años 1985 y 1986, con vistas a la elaboración de las cartas arqueológicas de Castuera-Zalamea de la Serena y don Benito. Los primeros resultados de estos trabajos de prospección pusieron enseguida de relieve las peculiaridades de esta comarca respecto al resto de la provincia badajocense, al comprobar la particular concentración en dicho espacio de diversos tipos de construcciones ciclópeas. Sin descartar la posibilidad de que los romanos hubieran construido algunos de estos recintos, la base teórica de nuestro proyecto, inicialmente, contemplaba la posibilidad de un origen prerromano de los mismos en función de los resultados obtenidos, años antes, en yacimientos similares en el sureste de la provincia de Córdoba. A medida que hemos ido avanzando en su estudio, basado hasta ahora en nuevas prospecciones y sondeos estratigráfic

    LoRa-Based System for Tracking Runners in Cross Country Races

    Full text link
    [EN] In recent years, there is an important trend in the organization of cross country races and popular races where hundred people usually participate. In these events, runners usually subject the body to extreme situations that can lead to various types of indisposition and they can also suffer falls. Currently, the electronic systems used in this type of racing refer only to whether a runner has passed through a checkpoint. However, it is necessary to implement systems that allow controlling the population of runners knowing their status all the time. For this reason, this paper proposes the design of a low-cost system for monitoring and controlling runners in this type of event. The system is formed by a network architecture in infrastructure mode based on Low-Power Wide-Area Network (LPWAN) technology. Each runner will carry an electronic device that will give their position and vital signs to be monitored. Likewise, it will incorporate an S.O.S. button that will allow sending a warning to the organization in order to help the person. All these data will be sent through the network to a database that will allow the organization and the public attending the race to check where the runner is and the history of their vital signs. This paper shows the proposed design to our system. Therefore, the paper will show the different practical experiments we have been carried out with the devices that have allowed proposing this design.This work has been partially supported by the Ministerio de Ciencia, Innovación y Universidades through the Ayudas para la adquisición de equipamiento científico-técnico, Subprograma estatal de infraestructuras de investigación y equipamiento científico-técnico (plan Estatal I+D+i 2017-2020) (project EQC2018-004988-P).Sendra, S.; Romero-Díaz, P.; García-Navas, JL.; Lloret, J.

    Durante las prospecciones arqueológicas realizadas en la comarca de La Serena (Badajoz), en 1985, se documentó la existencia de unas estructuras de reducidas dimensiones que, con poblamiento romano en superficie, se distribuían por el llano con una función que ignorábamos y con una filiación cultural que planteaba serias dudas. El análisis de esta serie de asentamientos apuntaba hacia la posibilidad de que nos encontráramos ante un tipo de hábitat específico de cuya existencia no había noticias hasta entonces en el panorama arqueológico extremeño.During the archaeological prospections carried out in the region of La Serena (Badajoz), in 1985, the existence of structures of small dimensions was documented, which, with Roman settlement on the surface, were distributed along the plain with a function that we did not know and with a filiation that raised serious doubts. The analysis of this series of settlements pointed to the possibility that we were facing a specific type of habitat whose existence had not been reported until then in the archaeological panorama from Extremadura.peerReviewe

    Robotics software frameworks for multi-agent robotic systems development

    Get PDF
    Robotics is an area of research in which the paradigm of Multi-Agent Systems (MAS) can prove to be highly useful. Multi-Agent Systems come in the form of cooperative robots in a team, sensor networks based on mobile robots, and robots in Intelligent Environments, to name but a few. However, the development of Multi-Agent Robotic Systems (MARS) still presents major challenges. Over the past decade, a high number of Robotics Software Frameworks (RSFs) have appeared which propose some solutions to the most recurrent problems in robotics. Some of these frameworks, such as ROS, YARP, OROCOS, ORCA, Open-RTM, and Open-RDK, possess certain characteristics and provide the basic infrastructure necessary for the development of MARS. The contribution of this work is the identification of such characteristics as well as the analysis of these frameworks in comparison with the general-purpose Multi-Agent System Frameworks (MASFs), such as JADE and Mobile-C.Ministerio de Ciencia e Innovación TEC2009-10639-C04-02Junta de Andalucía P06-TIC-2298Junta de Andalucía P08-TIC-0386

    Low Cost LoRa based Network for Forest Fire Detection

    Full text link
    [EN] Forest fires are one of the main environmental problems in the entire Mediterranean basin. In a context where low power and long-range networks (LPWAN) are increasingly common to the rise of Internet of Things (IoT) architecture, the interest in providing solutions to monitor scenarios and fire prevention based on these technologies is huge. This paper presents a low cost Long Range (LoRa) based network able to evaluate level of fire risk and the presence of a forest fire. The system is composed by a LoRa node and a set of sensors to measure the temperature, relative humidity, wind speed and CO2. The evaluation algorithm is based on the 30- 30-30 rule. Through website the users can see the parameters measured by nodes in real time. The system has been tested in a real environment and the results show that it is possible to cover a circular area of 1.1km or radius.This work has been partially supported by the Ministerio de Ciencia, Innovación y Universidades through the Ayudas para la adquisición de equipamiento científicotécnico, Subprograma estatal de infraestructuras de investigación y equipamiento científico-técnico (plan Estatal I+D+i 2017-2020) (project EQC2018-004988-P) and through the Research Contracts of Youth Employment of the University of Granada, through its operative program of Youth Guarantee of the Regional Government of Andalusia and the European Social Fund.Vega-Rodríguez, R.; Sendra, S.; Lloret, J.; Romero-Díaz, P.; García-Navas, JL.

    Chitosan (CTS) is a polysaccharide with a wide variety of applications in the biomedical field, owing to its outstanding disinfectant properties, biocompatibility and biodegradability, but with limited mechanical properties. The proposed strategy to improve CTS-based hydrogel properties in this study is the formation of a semi-interpenetrating polymer network (semi-IPN). In this way, a photo-initiated radical click reaction was proposed to obtain a synthetic polymer, whose components were included in a CTS solution, resulting in the semi-IPN network after UV illumination. Different crosslinking degrees (CD) and CTS/polymer ratios were evaluated through rheological characterization, along with an assessment of both variables based on an experimental model design, obtaining that, for every CTS/polymer ratio, intermediate values of CD (8 %) offered the best rheological properties. In addition, chemical and microstructural characterization were carried out for selected hydrogels, obtaining consistent results according to rheological characterization, as the 1/1 CTS/polymer ratio with CD 8 % hydrogel displayed the most homogeneous pore size and distribution, consequently leading to the best rheological performance.This study was financially supported by MCIN/AEI/10.13039/5 01100011033/FEDER, UE, through the project PID2021- 124294OB-C21.
