Object Detection from Thermal Infrared and Visible Light Cameras in Search and Rescue Scenes

Visual object recognition is a fundamental challenge for reliable search and rescue (SAR) robots, where vision can be limited by lighting and other harsh environmental conditions in disaster sites. The goal of this paper is to explore the use of thermal and visible light images for automatic object detection in SAR scenes. With this purpose, we have used a new dataset consisting of pairs of thermal infrared (TIR) and visible (RGB) video sequences captured from an all-terrain vehicle moving through several realistic SAR exercises participated by actual first response organisations. Two instances of the open source YOLOv3 convolutional neural network (CNN) architecture are trained from annotated sets of RGB and TIR images, respectively. In particular, frames are labelled with four representative classes in SAR scenes comprising both persons civilian and first-responder) and vehicles (Civilian-car and response-vehicle). Furthermore, we perform a comparative evaluation of these networks that can provide insight for future RGB/TIR fusion.This work has been done in the framework of the TRUST-ROB project, funded by the Spanish Government (RTI2018-093421-B-I00).

Dinámica de paisajes forestales en relación a la incidencia del fuego en España peninsular: 1987-2000

Forest fires play a determinant role in landscape configuration, that is, the type and the spatial distribution of major land cover types in large areas of Spain. One possible way to evaluate this role is by means of the comparison between the area affected by forest fires and changes in land cover types during a certain type period. Based on the importance of wildland fires during the last decades in Spain it is expected a strong relationship between landscape changes and fire occurrence. In order to validate this hypothesis we have analysed the relationship between the changes in land cover types identified in the two land cover classifications carried out until now in the European programme CORINE Land Cover (CLC) and fire occurrence in peninsular Spain for a similar time period. The analyses are based on non parametric correlations and in a canonical ordination analysis between several fire variables and the different types of land cover change in which the dynamic of forested landscapes has been resumed according to the two land cover classification used: CLC-1990 and CLC-2000. The territorial units used are the division of Spain in agrarian counties and the reference period the 14 years spanned between the satellite images used in each classification. Focussing of the forested area, the more important changes detected are the changes from woodland to non-woodland (21%), from non-woodland to woodland (23%) and changes between the different types of land-cover included in the non-woodland class (22%). These three types of changes, that accounted for a 66% of changes in forested areas, have been the more related to fire occurrence. The results show a strong relation between both processes. We have obtained statistically significant results in the correlation and also in the multivariate redundancy analyses. These results confirm the determinant role that fires have played, and certainly will play, in the vegetation dynamic of regions each time more prone to fire such as peninsular Spain.Los incendios forestales tienen en numerosas regiones de España un papel determinante en la configuración del paisaje, es decir, en el tipo de cubiertas vegetales y en la distribución espacial de éstas. Una manera de evaluar este papel es comparar la incidencia de los incendios forestales con los cambios registrados en la cubierta vegetal en un periodo de tiempo. Dada la importancia que el fuego ha tenido en las últimas décadas en España peninsular, sería de esperar una importante interrelación entre los cambios en el paisaje forestal y la incidencia de los incendios. Para validar esta hipótesis se han analizado las relaciones entre los cambios en los tipos de cubierta forestal identificados en las dos clasificaciones realizadas dentro del programa europeo CORINE Land Cover (CLC-1990 y CLC-2000) y la incidencia del fuego en España peninsular en un periodo de tiempo comparable. Los análisis se han basado en correlaciones no paramétricas y en un análisis canónico de ordenación entre variables relativas a la incidencia del fuego y los distintos tipos de cambios en los que se ha resumido la dinámica de los paisajes forestales. La base territorial elegida para estos análisis ha sido la división de España peninsular en comarcas agrarias y un periodo de aproximadamente 14 años que separan las imágenes Landsat empleadas en cada una de las dos clasificaciones. Centrados en la superficie forestal, los tipos de cambio más relevantes en el periodo analizado han sido los cambios de arbolado a desarbolado (21%), de desarbolado a arbolado (23%) y los cambios entre los distintos tipos de vegetación incluidos dentro de la clase superficie desarbolada (22%). Estos tres tipos de cambio, que han representado un 66% de los cambios en las superficies forestales, han sido también los más relacionados con la incidencia del fuego. Los resultados muestran que ambos procesos han estado inter-relacionados obteniendose valores significativos tanto en las correlaciones como en el análisis multivariante de redundancia. Estos resultados confirman el papel determinante que los incendios forestales han tenido, y presumiblemente seguirán teniendo, en la dinámica de la vegetación en regiones cada vez más susceptibles al fuego como España

Comparison between FS-MPC control strategy for an UPS inverter application in α-β and abc frames

The voltage source inverter (VSI) of an uninterruptible power supply (UPS) is a system where the main objective is to obtain a high quality output sinusoidal voltage with independence on the output load. For this reason, it includes an output LC filter. The presence of the filter increases the complexity of the controller design thus it is necessary to evaluate the performance of the control strategy in terms of the output voltage quality and computational cost of the algorithm. In this paper, both analysis are developed for the finite states model predictive control (FS-MPC) of a VSI performed in the abc and α-βframes. Both algorithms are summarized and compared in order to establish an objective criteria to choose among them when a hardware implementation is developed. Simulation results are presented for both algorithms to validate the analysis

Evaluation of primary care responsiveness by people with mental illness in Spain

Background The health system responsiveness is a concept developed by the World Health Organization that measures patients'' expectations for the non-medical care they receive. The aim of this study is to assess primary care responsiveness as seen by people with mental illness and to analyse the factors associated with poor responsiveness. Methods Cross-sectional descriptive study on 426 people with mental illness who had attended primary care consultations at least once in the previous 12 months. The responsiveness of the health system was determined through the short questionnaire "Multi-country Survey Study on Health and Health Systems Responsiveness". Differences in responsiveness by sociodemographic characteristics were compared through the Chi-squared test. Logistic regression identified the factors associated with poor responsiveness. Results Overall responsiveness was measured as good by 77.4% of patients, being this probability higher in the domains: dignity, confidentiality, and communication. The most valued domains by people with mental illness were prompt attention (42.4%), dignity (30.1%), and communication (17%). Only prompt attention scored high importance and poor responsiveness. In patients with an income lower than 900 euros per month and low level of studies, the probability of poor confidentiality responsiveness was multiplied by 3 and 2.7 respectively. Conclusions People with mental illness perceive good responsiveness from primary care in terms of dignity, confidentiality, and communication. Prompt attention, as the domain of greatest importance and worst valuation, should be prioritised through the implementation of organisational measures in health centres to reduce waiting times, especially in urban areas

Safety assessment of underground vehicles passing over highly resilient curved tracks in the presence of a broken rail

Vehicle–track interaction for a new resilient slab track designed to reduce noise and vibration levels was analysed, in order to assess the derailment risk on a curved track when encountering a broken rail. Sensitivity of the rail support spacing of the relative position of the rail breakage between two adjacent rail supports and of running speed were analysed for two different elasticities of the rail fastening system. In none of the cases analysed was observed an appreciable difference between either of the elastic systems. As was expected, the most unfavourable situations were those with greater rail support spacing and those with greater distance from the breakage to the nearest rail support, although in none of the simulations performed did a derailment occur when running over the broken rail. When varying the running speed, the most favourable condition was obtained for an intermediate speed, due to the superposition of two antagonistic effects

Scaling Out Evidence-Based Interventions Outside the U.S. Mainland: Social Justice or Trojan Horse?

Global health disparities continue to widen as professional standards for effectiveness of mental health services provision become more precise and difficult to achieve across varied economic and social contexts. Within the U.S., health disparities are evident in Latinx populations. Globally, the health disparities are also evident in Latin America as compared to the U.S. and other economically affluent nations. The diversification of psychology in content and persons has led to a unique opportunity to build bridges that can help reduce disparities in- and outside of the U.S. mainland. Collaborations can be of great use in addressing health disparities internationally but also are of critical importance in testing the ecological validity of existing interventions. It is imperative that researchers approach these exchanges as truly collaborative and power even, as researchers in all locations stand to learn and grow from the partnership, otherwise U.S.-based researchers can unwittingly engage intellectual colonization and advance cultural imperialism. U.S.-based researchers must be particularly thoughtful about disparities in both resources and consequences for success and failures in research contexts. We discuss specific failures, recoveries, and successes that may be useful to other researchers engaged, or seeking to engage in, international collaborations

Análisis de técnicas de aumento de datos y entrenamiento en YOLOv3 para detección de objetos en imágenes RGB y TIR del UMA-SAR Dataset

Este trabajo ha recibido financiación del proyecto nacional RTI2018-093421-B-I00El uso de imágenes de los espectros visible (RGB) e infrarrojo térmico (TIR) para la detección de objetos puede resultar crucial en aplicaciones donde las condiciones de visibilidad están limitadas, como la robótica para búsqueda y rescate en catástrofes. Para ello resulta beneficioso analizar cómo las técnicas de aprendizaje profundo basadas en redes neuronales convolucionales (CNN) pueden aplicarse a ambas modalidades. En este artículo se analizan diferentes configuraciones y parámetros para el entrenamiento de CNN tanto para imágenes térmicas como para imágenes equivalentes del espectro visible. En concreto, se aborda el problema del sobre-entrenamiento para determinar una configuración eficaz de técnicas de aumento de datos y parada temprana. El caso de estudio se ha realizado con la red de código abierto YOLOv3, pre-entrenada con el dataset RGB COCO y optimizada (o re-entrenada) con el conjunto público de datos UMA-SAR dataset, que incluye pares de imágenes RGB y TIR obtenidas en ejercicios realistas de rescate.Universidad de Málaga.
