Human-robot cooperation for robust surface treatment using non-conventional sliding mode control

© 2018 ISA This work presents a human-robot closely collaborative solution to cooperatively perform surface treatment tasks such as polishing, grinding, deburring, etc. The method considers two force sensors attached to the manipulator end-effector and tool: one sensor is used to properly accomplish the surface treatment task, while the second one is used by the operator to guide the robot tool. The proposed scheme is based on task priority and adaptive non-conventional sliding mode control. The applicability of the proposed approach is substantiated by experimental results using a redundant 7R manipulator: the Sawyer cobot

Impact of mineral dust on short wave and long wave radiation: evaluation of different vertically resolved parameterization sin 1-D radiative transfer computations

Aerosol radiative properties are investigated in southeastern Spain during a dust event on 16–17 June 2013 in the framework of the ChArMEx/ADRIMED (Chemistry-Aerosol Mediterranean Experiment/Aerosol Direct Radiative Impact on the regional climate in the MEDiterranean region) campaign. Particle optical and microphysical properties from ground-based sun/sky photometer and lidar measurements, as well as in situ measurements on board the SAFIRE ATR 42 French research aircraft, are used to create a set of different levels of input parameterizations, which feed the 1-D radiative transfer model (RTM) GAME (Global Atmospheric ModEl). We consider three datasets: (1) a first parameterization based on the retrievals by an advanced aerosol inversion code (GRASP; Generalized Retrieval of Aerosol and Surface Properties) applied to combined photometer and lidar data, (2) a parameterization based on the photometer columnar optical properties and vertically resolved lidar retrievals with the two-component Klett–Fernald algorithm, and (3) a parameterization based on vertically resolved optical and microphysical aerosol properties measured in situ by the aircraft instrumentation. Once retrieved, the outputs of the RTM in terms of both shortwave and longwave radiative fluxes are compared against ground and in situ airborne measurements. In addition, the outputs of the model in terms of the aerosol direct radiative effect are discussed with respect to the different input parameterizations. Results show that calculated atmospheric radiative fluxes differ no more than 7 % from the measured ones. The three parameterization datasets produce a cooling effect due to mineral dust both at the surface and the top of the atmosphere. Aerosol radiative effects with differences of up to 10 W m−2 in the shortwave spectral range (mostly due to differences in the aerosol optical depth) and 2 W m−2 for the longwave spectral range (mainly due to differences in the aerosol optical depth but also to the coarse mode radius used to calculate the radiative properties) are obtained when comparing the three parameterizations. The study reveals the complexity of parameterizing 1-D RTMs as sizing and characterizing the optical properties of mineral dust is challenging. The use of advanced remote sensing data and processing, in combination with closure studies on the optical and microphysical properties from in situ aircraft measurements when available, is recommended.This work is part of the ChArMEx project supported by CNRS-INSU, ADEME, Météo-France, and CEA in the framework of the multidisciplinary program MISTRALS (Mediterranean Integrated STudies at Regional And Local Scales; http://mistrals-home.org/, last access: 15 January 2018).

Automatic Bluefin Tuna (Thunnus thynnus) Biomass Estimation during Transfers Using Acoustic and Computer Vision Techniques

In this work, acoustic and computer vision techniques are combined to develop an automatic procedure for biomass estimation of tuna during transfers. A side scan sonar working at 200 kHz and a stereo camera, posi- tioned facing towards the surface to record the ventral aspect of fish, are set as acquisition equipment. Moreover, a floating structure has been devised to place the sensors between cages in transfers, creating a transfer canal that allows data acquisition while fish swim from donor to receiving cage. Biomass assessment is computed by counting transferred tuna and sizing a representative sample of the stock. The number of transferred tuna is automatically deduced from acoustic echograms by means of image processing techniques, whereas tuna size is computed from the stereo videos using our automatic computer vision procedure based on a deformable model of the fish ventral silhouette. The results show that the system achieves automatic tuna counting with error below 10%, achieving around 1% error in the best configuration, and automatic tuna sizing of more than 20% of the stock, with highly accurate Snout Fork Length estimation when compared to true data from harvests. These results fulfil the requirements imposed by International Commission for the Conservation of Atlantic Tunas for compliant transfer operations.Versión del editor1,42

Bluefin tuna (Thunnus thynnus) biomass estimation during transfers using acoustic and optic techniques

Our results show that the use of an acoustic transducer in transfers offers the possibility of performing an automatic counting with error below 10%, which is decreased to 1.2% after improving structure and algorithms. Moreover, the proposed procedure for automatic sizing using stereoscopic system achieved an accurate estimation of SFL distribution compared to true data from harvests, automatically measuring 20% of the fis

We report on aerosol optical properties observed under this extreme dust intrusion through passive and active remote sensing techniques. For that, AERONET (AErosol RObotic NETwork) and EARLINET (European Aerosol Research LIdar NETwork) databases are used. The sites considered are: Barcelona (41.38°N, 2.17°E), Burjassot (39.51°N, 0.42°W), Cabo da Roca (38.78°N, 9.50°W), Évora (38.57°N, 7.91°W), Granada (37.16°N, 3.61°W) and Madrid (40.45°N, 3.72°W). Large aerosol optical depths (AOD) and low Ångström exponents (AE) are observed. An AOD of 2.0 at 675 nm is reached in several stations. A maximum peak of 2.5 is registered in Évora. During and around the peak of AOD, AEs close to 0 and even slightly negative are measured. With regard to vertically-resolved aerosol optical properties, particle backscatter coefficients as high as 15 Mm−1 sr−1 at 355 nm are recorded at the lidar stations. Layer-mean lidar ratios are found in the range 40–55 sr at 355 nm and 34–61 sr at 532 nm during the event. The particle depolarization ratios are found to be constant inside the dust layer, and consistent from one site to another. Layer-mean values vary in the range 0.19–0.31. Another remarkable aspect of the event is the limited vertical distribution of the dust plume which never exceeds 5 km. The extreme aspect of the event also presented a nice case for testing the ability of two dust forecast models, BSC-DREAM8b and NMMB/BSC-Dust, to reproduce the arrival, the vertical distribution and the intensity of the dust plume over a long-range transport region. In the particular case of the February 2017 dust event, we found a large underestimation in the forecast of the extinction coefficient provided by BSC-DREAM8b at all heights independently of the site. In contrast NMMB/BSC-Dust forecasts presented a better agreement with the observations, especially in southwestern part of the IP. With regard to the forecast skill as a function of lead time, no clear degradation of the prognostic is appreciated at 24, 48 and 72 h for Évora and Granada stations (South). However the prognostic does degrade (bias increases and/or correlation decreases) for Barcelona (North), which is attributed to the fact that Barcelona is at a greater distance from the source region and to the singularity of the event.Funding from the H2020 program from the European Union (grant agreement no. 654109, 778349)Spanish Ministry of Industry, Economy and Competitiviness (MINECO, ref.

Proyecto BIACOP: estimación de biomasa en jaulas de Atún Rojo con métodos acústicos y ópticos

Este proyecto tiene como objeto final la configuración de un sistema que proporcione la estimación del número y la biomasa de atunes de forma automática en entornos semi-controlados. Para ello se llevarán a cabo desarrollos, que configuren la integración de los datos obtenidos por sistemas acústicos y ópticos en dicho entornos. En concreto este proyecto pretende: - Desarrollar un sistema automático que sea capaz de estimar la distribución de tallas y pesos de los atunes que habitan en una jaula flotante. - Desarrollar un sistema automático que cuantifique las capturas, tanto del número de individuos capturados como de la distribución de sus tallas y pesos, y por tanto de la biomasa total, durante el proceso de transferencia de los atunes entre jaulas. Para conseguir los objetivos será necesario realizar: 1. Una selección de componentes hardware y software que tengan un rendimiento apropiado para adquirir datos acústicos y ópticos en el medio marino 2. Fases de adquisición y almacenamiento de datos acústicos y ópticos para configurar bases de datos cuyo objetivos serán: a) evaluar las diferentes versiones del sistema durante la fase de desarrollo b) confeccionar estadísticas de valores y parámetros relacionales 3. Fases de pruebas y validación de los equipos y métodos desarrollados en situaciones reales de funcionamiento 4. Diseño e integración de aquellos elementos hardware del sistema acústico y del sistema de visión por computador que resulten necesarios para la configuración del sistema final 5. Implementación y desarrollo de algoritmos, tanto para el procesamiento de los datos acústicos, como para el procesamiento y análisis de las imágenes adquiridas, necesarios para el funcionamiento de la aplicación y del sistema final propuesto Las ventajas del sistema resultante frente a los ya existentes son: 1. Sistema totalmente automático: El sistema detectará de forma automática instantáneas adecuadas de los atunes en las que sea correcto adquirir valores biométricos de los mismos para caracterizar su talla y su peso. Para ello será necesario el procesamiento y sincronización de la señal acústica y óptica. 2. Sistema de gran precisión: El trabajar con dos tipos de datos (acústico y óptico) sobre los mismos individuos nos permite verificar los valores estimados sobre sus características biométricas y conseguir una mayor precisión y ajuste. 3. Sistema tolerante con aguas turbias o con poca transparencia: Los sistemas acústicos obtienen información con independencia de la turbidez o claridad del agua. El trabajar con datos acústicos nos permite dar referencias al sistema de visión sobre distancias de individuos detectados, consiguiendo una mejor aproximación del procesamiento de imágenes realizado. 4. Sistema respetuoso con el bienestar animal y su desarrollo: En este proyecto se propone un sistema no invasivo. Nuestro sistema estará dotado únicamente de los elementos tecnológicos y acústicos necesarios para extraer datos y del soporte de los mismos, y en todo caso del sistema de sujeción que confiera la necesaria estabilidad de los mismos. 5. Sistema para ventanas de transferencia de tamaño adecuado al atún rojo: La tecnología acústica proporciona información complementaria a los sistemas ópticos. La utilización de ambas tecnologías permitiría complementar la utilización de un sistema óptico estereoscópico, y mejorar la amplitud del campo efectivo de nuestro sistema, pudiendo prescindir de la información estereoscópica en los casos en que las distancias de trabajo dificultan su aplicación, o incluso ofrecer información puramente acústica. RESULTADOS La medida estereoscópica ventral automatizada de atunes en jaulas y transferencias ofrece nformación biométrica sin errores accidentales asociados a la medida del operador. Nuevas relaciones biométricas pueden estudiarse a partir de las herramientas desarrolladas. La utilización de una estructura de paso entre jaulas posibilita la instalación de sensores en posiciones estables y la repetibilidad de las condiciones de medida El uso de un transductor acústico en las transferencias ofrece el conteo automático con errores menores al 10 %Comisión Europea mediante la decisión ejecutiva de la Comisión de la UE de 10 de julio de 2013 (2013/410/UE), relativa a una participación financiera de la Unión en los programas de control de la actividad pesquera realizados por los estados miembros

El conflicto entre cristianos y musulmanes en las relaciones de sucesos : la liberación de Buda

Este trabajo propone el análisis de una selección de textos escritos en romance sobre la derrota turca y la toma de la ciudad de Buda en 1686, que denuncian la exultante acogida popular de la noticia de las gestas cristianas en Centroeuropa, la percepción del eterno conflicto entre Oriente y Occidente y la proyección del imaginario colectivo del siglo xvii acerca de la lucha contra los infieles.This paper offers the analysis of a selection of texts, written in Romance languages, about the Turkish defeat and the conquest of the city of Buda in 1686, which provide evidence of the popular exultation at the news of the Christian achievements in Central Europe, the perception of the eternal conflict between East and West, and the projection of the seventeenth-century collective imagination regarding the struggle against the infidel

Dietary α‐Linolenic Acid, Marine ω‐3 Fatty Acids, and Mortality in a Population With High Fish Consumption: Findings From the PREvención con DIeta MEDiterránea (PREDIMED) Study

Background: Epidemiological evidence suggests a cardioprotective role of α‐linolenic acid (ALA), a plant‐derived ω‐3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine ω‐3 fatty acids (long‐chain n‐3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to all‐cause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for long‐chain n‐3 polyunsaturated fatty acids (≥500 mg/day). Methods and Results: We longitudinally evaluated 7202 participants in the PREvención con DIeta MEDiterránea (PREDIMED) trial. Multivariable‐adjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9‐y follow‐up, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56–0.92) for all‐cause mortality and 0.95 (95% CI 0.58–1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for long‐chain n‐3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67–1.05) for all‐cause mortality, 0.61 (95% CI 0.39–0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29–0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22–1.01) for sudden cardiac death. The highest reduction in all‐cause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45–0.87]). Conclusions: In participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to all‐cause mortality, whereas protection from cardiac mortality is limited to fish‐derived long‐chain n‐3 polyunsaturated fatty acids.
