    Synthèse et analyse d\u27une enquête menée dans le cadre du projet Form@doct, projet de didacticiel proposé par les SCD des universités de Bretagne : UBO, UBS, Rennes 2, Rennes 1, INSA et par l’URFIST de Rennes, et déposé dans le cadre du PRES de l’Université Européenne de Bretagne. Il s’adresse en priorité aux doctorants de Bretagne et vise à développer la connaissance et la maîtrise de l’information scientifique des doctorants. L’objectif pédagogique global est de former les doctorants à la maîtrise des notions, des compétences et des savoir-faire de l’information scientifique qui sont mobilisés dans le travail de recherche doctorale.

    Towards an AI assistant for human grid operators

    Get PDF
    Power systems are becoming more complex to operate in the digital age. As a result, real-time decision-making is getting more challenging as the human operator has to deal with more information, more uncertainty, more applications and more coordination. While supervision has been primarily used to help them make decisions over the last decades, it cannot reasonably scale up anymore. There is a great need for rethinking the human-machine interface under more unified and interactive frameworks. Taking advantage of the latest developments in Human-machine Interactions and Artificial intelligence, we share the vision of a new assistant framework relying on an hypervision interface and greater bidirectional interactions. We review the known principles of decision-making that drives the assistant design and supporting assistance functions we present. We finally share some guidelines to make progress towards the development of such an assistant

    Spatial and seasonal patterns of FMD primary outbreaks in cattle in Zimbabwe between 1931 and 2016

    Foot and mouth disease (FMD) is an important livestock disease impacting mainly intensive production systems. In southern Africa, the FMD virus is maintained in wildlife and its control is therefore complicated. However, FMD control is an important task to allow countries access to lucrative foreign meat market and veterinary services implement drastic control measures on livestock populations living in the periphery of protected areas, negatively impacting local small-scale livestock producers. This study investigated FMD primary outbreak data in Zimbabwe from 1931 to 2016 to describe the spatio-temporal distribution of FMD outbreaks and their potential drivers. The results suggest that: (i) FMD outbreaks were not randomly distributed in space across Zimbabwe but are clustered in the Southeast Lowveld (SEL); (ii) the proximity of protected areas with African buffalos was potentially responsible for primary FMD outbreaks in cattle; (iii) rainfall per se was not associated with FMD outbreaks, but seasons impacted the temporal occurrence of FMD outbreaks across regions; (iv) the frequency of FMD outbreaks increased during periods of major socio-economic and political crisis. The differences between the spatial clusters and other areas in Zimbabwe presenting similar buffalo/cattle interfaces but with fewer FMD outbreaks can be interpreted in light of the recent better understanding of wildlife/livestock interactions in these areas. The types of wildlife/livestock interfaces are hypothesized to be the key drivers of contacts between wildlife and livestock, triggering a risk of FMD inter-species spillover. The management of wildlife/livestock interfaces is therefore crucial for the control of FMD in southern Africa

    Une culture informationnelle commune aux doctorants ?

    Comment répondre à la diversité des besoins disciplinaires lors des formations des doctorants à l’information scientifique ? Quel peut être, à ce niveau de spécificité des besoins, le sens d’une offre de formation commune, transversale ? Cette question des contenus des formations à la maîtrise de l’information n’est pas nouvelle et ne concerne pas seulement le doctorat. En effet, à tous les niveaux de licence, master et doctorat (LMD) intervient le problème d’une triple articulation à trouver..

    193nm immersion lithography studies with a double grating high NA achromatic interferometer

    As immersion lithography will be the lithography technique for sub-65nm generation device fabrication, benefits and drawbacks of the introduction of an immersion fluid between the imaging optics and the wafer have to be studied. In this context, it is of high interest to be able to understand the properties of hyper high NA imaging and to do so, to have access to a technique which can mimic an industrial immersion stepper by having the possibility to tune the polarization state and numerical aperture. Interferometric lithography has proven to be a useful method to study projection imaging at high numerical aperture (NA). It has been shown to help addressing several issues of immersion lithography such as polarization state impact on imaging, photoresists material screening as well as preliminary defectivity considerations due to the introduction of water and high index fluid studies [1, 2, 3]. In the frame of this work, a home-built interferometer with immersion lithography capabilities has been fully designed and mounted in our facilities. Specific designs have been made in order to reach NAs as high as 1.4. All issues preventing the printing of high-contrasted lines over a large area, such as laser beam uniformity and vibrations control have been addressed and 40-nm-half-pitch resist lines can be currently printed with water immersion lithography. As a result, the interferometer has been used to screen resist and topcoat candidates for immersion lithography before their introduction in a production environment. An overview of our results is presented, focusing on the topcoat/resist compatibility. Besides, in order to prepare hyper NA lithography, We have implemented a simulation model which can be used to predict the light distribution inside a photolithographic stack. This model enables us to predict the resist image created by the interference of two coherent beams in the photo-resist volume. Simulations of polarization effects at oblique angles will be presented as well as the evaluation of image contrast in both TE and TM polarization. The contrast in TM polarization is dropping with increasing NA. Finally, we validate those predictions by experiments on our interferometer
