description Publication2019 France FrenchPublisher:HAL CCSD Authors: Haliyo, Sinan;Haliyo, Sinan;Ce manuscrit retrace l'avancement de mes activités de recherche depuis mon recrutement en 2004 comme maître de conférences au Laboratoire de Robotique de Paris, UPMC, jusqu'à maintenant où je dirige l'équipe "Interactions MultiÉchelles", fondée en 2018 à l'Institut des Systèmes Intelligents et de Robotique, Sorbonne Université, Paris.Le fil conducteur de ces activités est l'interaction de l'humain avec un système distant, et plus particulièrement quand ce système opère dans le micromonde: il s'agit des échantillons dont les dimensions sont inférieures au millimètre, ou encore quand la précision et la résolution recherchées s'expriment en 'micro' ou 'nano'. Les applications se situent dans le domaine de l'instrumentation scientifique, de la physique à la biologie, dans la chirurgie, ainsi que dans la conception, la fabrication et l'assemblage des systèmes de précision pour les technologies émergentes. Dans ce cadre, mes activités se préoccupent aussi bien de la perception, de l'haptique et des interfaces homme/machine que de la robotique. La place centrale de l'humain dans ces domaines est aussi la clef de voûte de l'équipe Interactions MultiÉchelles.

It has the potential to achieve automated nano-robotic tasks such as nano-handling and nano-assembly. Path following control of nano-robot end effectors using SEM vision feedback is a key for an intuitive programming of elementary robotic tasks sequences. It requires the ability to track end effectors under various SEM scan speeds. SEM suffers however from tricky issues that limits robotic tracking capabilities. This paper focuses on one specific issue related to the compromise between the scan speed and the image quality. This restriction seriously limits the performance of conventional vision tracking algorithms when used with electron images. At high scan speed, the image quality is very noisy making very difficult to differentiate the robot end effector from the background, hence limiting the tracking capabilities. The work related in this paper explores for the first time the potential value of Convolutional Neural Networks (ConvNet) in the context of nano-robotic vision tracking inside SEM. The aim is to localize an end-effector, AFM cantilever in the case of the study, from SEM images for any scan speed configuration and despite of low images quality. For that purpose, a data set of AFM tip images is build up from SEM images for the learning algorithm. Network performances are estimated under different SEM scan speeds. Thanks to the learning algorithm, experimental results show robust AFM tip tracking capabilities inside the SEM under various scan speed conditions.

Electronic skin (e-skin) is a crucial technology for these purposes. Artificial tactile skin that can play the roles of human skin remains a distant possibility because of hard issues in resilience, manufacturing, mechanics , sensorics, electronics, energetics, information processing, and transport. Taken together, these issues make it difficult to bestow robots, or prosthetic devices, with effective tactile skins. Nonetheless, progress over the past few years in relation with the above issues has been encouraging, and we have achieved close to providing some of the abilities of biological skin with the advent of deformable sensors and flexible electronics. The naive imitation of skin morphology and sensing an impoverished set of mechanical and thermal quantities are not sufficient. There is a need to find more efficient ways to extract tactile information from mechanical contact than those previously available. Renewed interest in neuromorphic tactile skin is expected to bring some fresh ideas in this field. This article reviews these new developments, particularly related to the handling of tactile data, energy autonomy, and large-area manufacturing. The challenges in relation with these advances for tactile sensing and haptics in robotics and prosthetics are discussed along with potential solutions. International audience

ONERA is currently conducting a study on the feasibility of an imaging interferometer for Earth observation from a GEO orbit. During this study, some key elements for the definition of such an instrument have been identified and studied. The results obtained so far confirm the applicability of wide-field optical interferometry with a Michelson-type instrument for Earth observation from a GEO orbit.

A major challenge for untethered microscale mobile robotics is the control of objects for precise and fast displacements. In this work, we propose to use an alternative implementation of a model based on elliptic integral functions to control magnetically actuated micro-robots. It allows to compute the magnetic field even in the area close to the coil quickly and accurately. This model is evaluated numerically and compared to classical approaches - dipole approximation, map-based interpolation and classical elliptic integral models - in terms of accuracy, computation time and memory requirement. Simulation results show that this works allows to have an accurate model in the whole workspace by avoiding numerical issues encountered in previous works. It can be computed in a few milliseconds, making it the right candidate for closed-loop control of magnetically actuated micro-robots. International audience

Climate change directly threatens food security in West Africa through a negative impact on productivity of the main staple food crops. However, providing consistent future crop yield projections in the region remain challenging because of uncertainty in the response of the regional climate to the CO2 increase and in the response of the cultivated crop to this altered climate with more CO2 in the atmosphere. Here, we analyse a set of idealised climate simulations to investigate the effect of CO2 concentration increase on the West African monsoon and potential impacts on crop yields of maize. On the one hand, simulations with prescribed SST and quadrupled CO2 concentration are analysed to study the atmospheric response to direct radiative forcing induced by increasing CO2 concentration, not mediated by ocean heat capacity. On the other hand, simulations with prescribed SST augmented by 4 K are analysed to study the atmospheric response to the global ocean warming expected as a consequence of the increasing CO2 radiative forcing. We show that if CO2 concentration increase has a positive impact on crop yield due to the fertilisation effect, it also has a direct effect on the monsoon which acts to increase (decrease) rainfall in the Eastern (Western) part of the Sahel and increase (decrease) crop yields consequently. Finally, we show that SST warming acts to reduce rainfall and increase local temperatures leading to strong reduction of crop yield. The reduction of crop yield is more important in the Eastern part of the Sahel where the warming is more intense than in the Western part of the Sahel. Overall, positive effects are weaker and more uncertain than the negative effects in the analysed simulations. International audience

Weather radar imaging has been identified in the literature as the best way to measure rainfall on a large domain, with a fine spatial and temporal resolution. This paper describes two methods allowing to improve rain nowcast from radar images at two different scales. These methods are further compared to an operational chain relying on only one type of radar observation. The comparison is led with regional and local criteria. For both, significant improvements are quantified compared to the original method. International audience

Abstract Retrieving concentrations of minor atmospheric trace gases from satellite observations is challenging due to their weak spectral signature. Here we present a new version of the ANNI (Artificial Neural Network for Infrared Atmospheric Sounding Interferometer, IASI) retrieval framework, which relies on a hyperspectral range index (HRI) for the quantification of the gas spectral signature and on an artificial feedforward neural network to convert the HRI into a gas total column. We detail the different steps of the retrieval method, especially where they differ from previous work, and apply the retrieval to three important volatile organic compounds: methanol (CH3OH), formic acid (HCOOH), and peroxyacetyl nitrate (PAN). The comparison of the retrieved columns with those from an optimal estimation inversion retrieval shows an overall excellent agreement: differences occur mainly when the sensitivity to the target gas is low and are consistent with the conceptual differences between the two approaches. We present retrieval examples over selected regions, comparison with previously developed products, and the global seasonal distributions including the first global distributions of PAN on a daily basis. The ANNI retrieval has been carried out on the whole time series of IASI observations (2007–2018), so that currently over 10 years of twice-daily global CH3OH, HCOOH, and PAN total column distributions have been produced. This unique data set opens avenues for tackling important questions related to sources, transport, and transformation of volatile organic compounds in the global atmosphere. info:eu-repo/semantics/published SCOPUS: ar.j

Through its important role in the formation of particulate matter, atmospheric ammonia affects air quality and has implications for human health and life expectancy1,2. Excess ammonia in the environment also contributes to the acidification and eutrophication of ecosystems3,4,5 and to climate change6. Anthropogenic emissions dominate natural ones and mostly originate from agricultural, domestic and industrial activities7. However, the total ammonia budget and the attribution of emissions to specific sources remain highly uncertain across different spatial scales7,8,9. Here we identify, categorize and quantify the world’s ammonia emission hotspots using a high-resolution map of atmospheric ammonia obtained from almost a decade of daily IASI satellite observations. We report 248 hotspots with diameters smaller than 50 kilometres, which we associate with either a single point source or a cluster of agricultural and industrial point sources—with the exception of one hotspot, which can be traced back to a natural source. The state-of-the-art EDGAR emission inventory10 mostly agrees with satellite-derived emission fluxes within a factor of three for larger regions. However, it does not adequately represent the majority of point sources that we identified and underestimates the emissions of two-thirds of them by at least one order of magnitude. Industrial emitters in particular are often found to be displaced or missing. Our results suggest that it is necessary to completely revisit the emission inventories of anthropogenic ammonia sources and to account for the rapid evolution of such sources over time. This will lead to better health and environmental impact assessments of atmospheric ammonia and the implementation of suitable nitrogen management strategies. International audience

description Publication2019 France FrenchPublisher:HAL CCSD Authors: Haliyo, Sinan;Haliyo, Sinan;Ce manuscrit retrace l'avancement de mes activités de recherche depuis mon recrutement en 2004 comme maître de conférences au Laboratoire de Robotique de Paris, UPMC, jusqu'à maintenant où je dirige l'équipe "Interactions MultiÉchelles", fondée en 2018 à l'Institut des Systèmes Intelligents et de Robotique, Sorbonne Université, Paris.Le fil conducteur de ces activités est l'interaction de l'humain avec un système distant, et plus particulièrement quand ce système opère dans le micromonde: il s'agit des échantillons dont les dimensions sont inférieures au millimètre, ou encore quand la précision et la résolution recherchées s'expriment en 'micro' ou 'nano'. Les applications se situent dans le domaine de l'instrumentation scientifique, de la physique à la biologie, dans la chirurgie, ainsi que dans la conception, la fabrication et l'assemblage des systèmes de précision pour les technologies émergentes. Dans ce cadre, mes activités se préoccupent aussi bien de la perception, de l'haptique et des interfaces homme/machine que de la robotique. La place centrale de l'humain dans ces domaines est aussi la clef de voûte de l'équipe Interactions MultiÉchelles.

It has the potential to achieve automated nano-robotic tasks such as nano-handling and nano-assembly. Path following control of nano-robot end effectors using SEM vision feedback is a key for an intuitive programming of elementary robotic tasks sequences. It requires the ability to track end effectors under various SEM scan speeds. SEM suffers however from tricky issues that limits robotic tracking capabilities. This paper focuses on one specific issue related to the compromise between the scan speed and the image quality. This restriction seriously limits the performance of conventional vision tracking algorithms when used with electron images. At high scan speed, the image quality is very noisy making very difficult to differentiate the robot end effector from the background, hence limiting the tracking capabilities. The work related in this paper explores for the first time the potential value of Convolutional Neural Networks (ConvNet) in the context of nano-robotic vision tracking inside SEM. The aim is to localize an end-effector, AFM cantilever in the case of the study, from SEM images for any scan speed configuration and despite of low images quality. For that purpose, a data set of AFM tip images is build up from SEM images for the learning algorithm. Network performances are estimated under different SEM scan speeds. Thanks to the learning algorithm, experimental results show robust AFM tip tracking capabilities inside the SEM under various scan speed conditions.

Electronic skin (e-skin) is a crucial technology for these purposes. Artificial tactile skin that can play the roles of human skin remains a distant possibility because of hard issues in resilience, manufacturing, mechanics , sensorics, electronics, energetics, information processing, and transport. Taken together, these issues make it difficult to bestow robots, or prosthetic devices, with effective tactile skins. Nonetheless, progress over the past few years in relation with the above issues has been encouraging, and we have achieved close to providing some of the abilities of biological skin with the advent of deformable sensors and flexible electronics. The naive imitation of skin morphology and sensing an impoverished set of mechanical and thermal quantities are not sufficient. There is a need to find more efficient ways to extract tactile information from mechanical contact than those previously available. Renewed interest in neuromorphic tactile skin is expected to bring some fresh ideas in this field. This article reviews these new developments, particularly related to the handling of tactile data, energy autonomy, and large-area manufacturing. The challenges in relation with these advances for tactile sensing and haptics in robotics and prosthetics are discussed along with potential solutions. International audience

ONERA is currently conducting a study on the feasibility of an imaging interferometer for Earth observation from a GEO orbit. During this study, some key elements for the definition of such an instrument have been identified and studied. The results obtained so far confirm the applicability of wide-field optical interferometry with a Michelson-type instrument for Earth observation from a GEO orbit.

A major challenge for untethered microscale mobile robotics is the control of objects for precise and fast displacements. In this work, we propose to use an alternative implementation of a model based on elliptic integral functions to control magnetically actuated micro-robots. It allows to compute the magnetic field even in the area close to the coil quickly and accurately. This model is evaluated numerically and compared to classical approaches - dipole approximation, map-based interpolation and classical elliptic integral models - in terms of accuracy, computation time and memory requirement. Simulation results show that this works allows to have an accurate model in the whole workspace by avoiding numerical issues encountered in previous works. It can be computed in a few milliseconds, making it the right candidate for closed-loop control of magnetically actuated micro-robots. International audience

Climate change directly threatens food security in West Africa through a negative impact on productivity of the main staple food crops. However, providing consistent future crop yield projections in the region remain challenging because of uncertainty in the response of the regional climate to the CO2 increase and in the response of the cultivated crop to this altered climate with more CO2 in the atmosphere. Here, we analyse a set of idealised climate simulations to investigate the effect of CO2 concentration increase on the West African monsoon and potential impacts on crop yields of maize. On the one hand, simulations with prescribed SST and quadrupled CO2 concentration are analysed to study the atmospheric response to direct radiative forcing induced by increasing CO2 concentration, not mediated by ocean heat capacity. On the other hand, simulations with prescribed SST augmented by 4 K are analysed to study the atmospheric response to the global ocean warming expected as a consequence of the increasing CO2 radiative forcing. We show that if CO2 concentration increase has a positive impact on crop yield due to the fertilisation effect, it also has a direct effect on the monsoon which acts to increase (decrease) rainfall in the Eastern (Western) part of the Sahel and increase (decrease) crop yields consequently. Finally, we show that SST warming acts to reduce rainfall and increase local temperatures leading to strong reduction of crop yield. The reduction of crop yield is more important in the Eastern part of the Sahel where the warming is more intense than in the Western part of the Sahel. Overall, positive effects are weaker and more uncertain than the negative effects in the analysed simulations. International audience

Weather radar imaging has been identified in the literature as the best way to measure rainfall on a large domain, with a fine spatial and temporal resolution. This paper describes two methods allowing to improve rain nowcast from radar images at two different scales. These methods are further compared to an operational chain relying on only one type of radar observation. The comparison is led with regional and local criteria. For both, significant improvements are quantified compared to the original method. International audience

Abstract Retrieving concentrations of minor atmospheric trace gases from satellite observations is challenging due to their weak spectral signature. Here we present a new version of the ANNI (Artificial Neural Network for Infrared Atmospheric Sounding Interferometer, IASI) retrieval framework, which relies on a hyperspectral range index (HRI) for the quantification of the gas spectral signature and on an artificial feedforward neural network to convert the HRI into a gas total column. We detail the different steps of the retrieval method, especially where they differ from previous work, and apply the retrieval to three important volatile organic compounds: methanol (CH3OH), formic acid (HCOOH), and peroxyacetyl nitrate (PAN). The comparison of the retrieved columns with those from an optimal estimation inversion retrieval shows an overall excellent agreement: differences occur mainly when the sensitivity to the target gas is low and are consistent with the conceptual differences between the two approaches. We present retrieval examples over selected regions, comparison with previously developed products, and the global seasonal distributions including the first global distributions of PAN on a daily basis. The ANNI retrieval has been carried out on the whole time series of IASI observations (2007–2018), so that currently over 10 years of twice-daily global CH3OH, HCOOH, and PAN total column distributions have been produced. This unique data set opens avenues for tackling important questions related to sources, transport, and transformation of volatile organic compounds in the global atmosphere. info:eu-repo/semantics/published SCOPUS: ar.j

Through its important role in the formation of particulate matter, atmospheric ammonia affects air quality and has implications for human health and life expectancy1,2. Excess ammonia in the environment also contributes to the acidification and eutrophication of ecosystems3,4,5 and to climate change6. Anthropogenic emissions dominate natural ones and mostly originate from agricultural, domestic and industrial activities7. However, the total ammonia budget and the attribution of emissions to specific sources remain highly uncertain across different spatial scales7,8,9. Here we identify, categorize and quantify the world’s ammonia emission hotspots using a high-resolution map of atmospheric ammonia obtained from almost a decade of daily IASI satellite observations. We report 248 hotspots with diameters smaller than 50 kilometres, which we associate with either a single point source or a cluster of agricultural and industrial point sources—with the exception of one hotspot, which can be traced back to a natural source. The state-of-the-art EDGAR emission inventory10 mostly agrees with satellite-derived emission fluxes within a factor of three for larger regions. However, it does not adequately represent the majority of point sources that we identified and underestimates the emissions of two-thirds of them by at least one order of magnitude. Industrial emitters in particular are often found to be displaced or missing. Our results suggest that it is necessary to completely revisit the emission inventories of anthropogenic ammonia sources and to account for the rapid evolution of such sources over time. This will lead to better health and environmental impact assessments of atmospheric ammonia and the implementation of suitable nitrogen management strategies. International audience
