Integration of a Canine Agent in a Wireless Sensor Network for Information Gathering in Search and Rescue Missions

Search and rescue operations in the context of emergency response to human or natural disasters have the major goal of finding potential victims in the shortest possible time. Multi-agent teams, which can include specialized human respondents, robots and canine units, complement the strengths and weaknesses of each agent, like all-terrain mobility or capability to locate human beings. However, efficient coordination of heterogeneous agents requires specific means to locate the agents, and to provide them with the information they require to complete their mission. The major contribution of this work is an application of Wireless Sensor Networks (WSN) to gather information from a multi-agent team and to make it available to the rest of the agents while keeping coverage. In particular, a canine agent has been equipped with a mobile node installed on a harness, providing information about the dog’s location as well as gas levels. The configuration of the mobile node allows for flexible arrangement of the system, being able to integrate static as well as mobile nodes. The gathered information is available at an external database, so that the rest of the agents and the control center can use it in real time. The proposed scheme has been tested in realistic scenarios during search and rescue exercises

Ingeniería Basada en Modelos en Prácticas de Robótica

Muñoz-Ramírez, A.J., Fernández-Lozano, J.J. y Gómez-de-Gabriel, J.M. (2015), "Ingeniería Basada en Modelos en Prácticas de Robótica", XXXVI Jornadas de Automática CEA/IFAC, Bilbao 2015.En este artículo se recoge la experiencia de usar una herramienta de desarrollo de ingeniería basada en modelos ó MDE (Model-Driven Engineering) para la realización de clases prácticas de robótica. La principal característica de los enfoques es que se prescinde de la fase de programación, por lo que se puede pasar del diseño a la implementación de manera autom´atica permitiendo dedicar más tiempo a los objetivos del aprendizaje. Para determinar la eficiencia de estas herramientas se ha utilizado una plataforma robótica móvil y se han realizado experimentos con alumnos utilizando Simulink con generación de código de Arduino y se han medido los resultados de manera subjetiva y objetiva.Universidad de Málaga.

SafeWalks: aplicación móvil de supervisión de pacientes de Alzheimer

El principal objetivo de Internet of Things (IoT) es integrar las tecnologías informáticas en el quehacer cotidiano de las personas, facilitando su interacción con un entorno de dispositivos interconectados, pero el estado actual del arte hace que dicha interacción esté aún lejos de resultar trivial, precisando de continua intervención del usuario. El modelo People as a Service (PeaaS) pretende facilitar estas tareas por medio del uso del teléfono móvil como interfaz del usuario con IoT. PeaaS permite elaborar un perfil sociológico del usuario, que puede ser explotado por el mismo y servido a terceros de forma controlada. En este trabajo presentamos una aplicación móvil para la supervisión de personas afectadas de alzheimer como prueba de concepto del modelo PeaaS, teniendo como resultado una funcionalidad que va mucho más allá de la ofrecida por otros productos similares en este campo.Universidad de Málaga.

Women\u27s beach handball game statistics: Differences and predictive power for winning and losing teams

The objectives of the present study were: (i) to compare beach handball game-related statistics by match outcome (winning and losing teams), and (ii) to identify characteristics that discriminate performances in the match. The game-related statistics of the 72 women’s matches played in the VIII Women’s Beach Handball World Championship (2018) were analysed. The game-related statistics were taken from the official Web page. A validation of the data showed their reliability to be very good (the inter-observer mean reliability was α=0.82 and the intra-observer mean was α=0.86). For the differences between winning/losing teams a parametric (unpaired t-test) or non-parametric (Mann-Whitney U test) test was applied depending on whether the variable met or did not meet normality, respectively. A stepwise discriminant analysis was then performed to determine the variables that predicted performance (victory or defeat). Five variables showed differences between the winning and losing teams: total points (p<.001; ES=1.09), technical faults (p<.001; ES=‑0.96), the number of players with either negative (p<.001; ES=‑0.86) or positive (p<.001; ES=1.05) valuations and overall valuation (p<.001; ES=1.29). The predictive model correctly classified 80.6% of the matches using two variables (Wilks’s λ=0.618; canonical correlation index=0.618): overall valuation and GK shots

Decomposition Analysis of the Aggregate Carbon Intensity (ACI) of the Power Sector in Colombia—A Multi-Temporal Analysis

This paper presents the application of the Logarithmic Mean Divisia Index Decomposition Analysis (LMDI) to the aggregate carbon intensity (ACI) of the power sector in Colombia in the period 1990–2020, with the aim of identifying the main drivers influencing the ACI change. The analysis performed identifies the main drivers among: carbon intensity, generation efficiency, and contribution of fossil generation at the specific and total level of electricity production. The analysis is performed at the aggregate and disaggregated level of fossil fuels. Due to the highly variable behavior of the ACI, a multi-temporal decomposition is performed in the eight presidential administrations in the period of analysis. For each period, the main drivers are identified and the energy policy implications and their effects on the operation and management of the power sector are analyzed. The results show that the main driver is the fossil share of total energy production. Important effects on thermal generation efficiency and fossil energy mix were also identified in some analysis periods. The need for effective long-term policies and regulation in relation to the factors influencing the ACI was identified. It is recommended to accelerate the diversification of the energy mix of the power sector and the permanent monitoring of the behavior of the drivers

High-Intensity Focused Ultrasound in Small Renal Masses

High-intensity focused ultrasound (HIFU) competes with radiofrequency and cryotherapy for the treatment of small renal masses as a third option among ablative approaches. As an emerging technique, its possible percutaneous or laparoscopic application, low discomfort to the patient and the absence of complications make this technology attractive for the management of small renal masses. This manuscript will focus on the principles, basic research and clinical applications of HIFU in small renal masses, reviewing the present literature. Therapeutic results are controversial and from an clinical view, HIFU must be considered a technique under investigation at present time. Further research is needed to settle its real indications in the management of small renal masses; maybe technical improvements will certainly facilitate its use in the management of small renal masses in the near future
