Échantillonnage adaptatif optimal dans les champs de Markov, application à l’échantillonnage d’une espèce adventice
2012
This work is divided into two parts: (i) the theoretical study of the problem of adaptive sampling in Markov Random Fields (MRF) and (ii) the modeling of the problem of weed sampling in a crop field and the design of adaptive sampling strategies for this problem. For the first point, we first modeled the problem of finding an optimal sampling strategy as a finite horizon Markov Decision Process (MDP). Then, we proposed a generic algorithm for computing an approximate solution to any finite horizon MDP with known model. This algorithm, called Least-Squared Dynamic Programming (LSDP), combines the concepts of dynamic programming and reinforcement learning. It was then adapted to compute adapt…
In Situ, Airborne Instrumentation: Addressing and Solving Measurement Problems in Ice Clouds
2012
The workshop on in situ airborne instrumentation: addressing and solving measurement problems in ice clouds, June 25-27, 2010, Oregon, aimed to identify unresolved questions concerning ice formation and evolution in ice clouds, assess the current state of instrumentation that can address these problems, introduce emerging technology that may overcome current measurement issues, and recommend future courses of action to improve our understanding of ice cloud microphysical. Eleven presentations were made covering measurement challenges associated measuring the composition and concentration of all the modes of ice nuclei (IN), measuring the morphology, mass, surface, and optical properties of …
Carbonated Inheritance in the Eastern Tibetan Lithospheric Mantle: Petrological Evidences and Geodynamic Implications
2020
International audience; The timing and mechanism of formation of the Tibet Plateau remain elusive, and even the present-day structure of the Tibetan lithosphere is hardly resolved, due to conflicting interpretations of the geophysical data. We show here that significant advances in our understanding of this orogeny could be achieved through a better assessment of the composition and rheological properties of the deepest parts of the Tibetan lithosphere, leading in particular to a reinterpretation of the global tomographic cross sections. We report mantle phlogopite xenocrysts and carbonate-bearing ultramafic cumulates preserved in Eocene potassic rocks from the Eastern Qiangtang terrane, wh…
Evaluation ex ante des conséquences de l'adoption de la production intégrée en grandes cultures à l'échelle de la Bourgogne
2015
The agriculture in France is under intense pressure. Farmers are asked to change their crop management, to evolve toward agroecology, to follow the principles of Integrated Pest Management (IPM) and to reduce pesticide use. However such an evolution toward an alternative agricultural model will be possible only if innovative cropping systems are able to maintain competitive and profitable farms.The aim of our work is to contribute to the debates about this issue, by evaluating ex ante the potential consequences of adopting the principles of IPM over one whole agricultural region, taking into account the diversity of production situations within this region. We considered the Burgundy region…
Des canaux Ioniques de la membrane plasmique lors de la mort cellulaire programmée induite par l’ozone chez A. thaliana
2011
Tropospheric ozone is a major secondary pollutant. In addition to its role in greenhouse effect gas, ozone is one of the most toxic air pollutants, and its pollution affects both human health and crop productivity. The work presented in this thesis concerns the role of ion channels in the plasma membrane in response to acute exposure to ozone and their interactions with signaling events leading to O3-induced PCD in A. Thaliana cultured cells. We have shown that cell death was genetically controlled and characterized by cell shrinkage similar to the mechanism of "Apoptosis Volume Decrease" (AVD) described in animal. This process is initially promoted by an early activation of a plasma membra…

Focal Points in Collective Free Improvisation
2013
OLLECTIVE FREE IMPROVISATION (herein abbreviated as CFI), while not a recent phenomenon in music (free jazz’s first experiments date from the late 1950s), remains under-studied. The extant literature either deals with political aspects (Carles and Comolli 2000) or tries to analyze the resulting music, using musicological tools (Jost 1994) or new concepts drawn from the complexity sciences (Borgo 2005). My research on CFI focuses on a cognitive approach, in order to understand the process of collective improvisation: 1 how a group of improvisers who do not know each other and are not using a common referent 2 (Pressing 1988) can answer the challenge of making music together. This paper deals…
L'obsolescence programmée a des petits frères !
2020
International audience; Retour sur les articles L. 441-3 à L. 441-5 du code de la consommation issus de la loi n° 2020-105 du 10 février 2020 relative à la lutte contre le gaspillage et à l'économie circulaire
Liszt, lectures et écritures
2013
International audience; Trois universités françaises se sont associées afin de rendre hommage à Franz Liszt, le plus européen des compositeurs du XIXe siècle, et célébrer ainsi le bicentenaire de sa naissance en 2011. Trois colloques dans trois villes différentes, Rennes, Dijon et Strasbourg, ont souhaité aborder trois aspects différents de sa personnalité artistique, littéraire, politique et son inscription dans les courants culturels de son temps.Critique musical et littéraire, critique d’art, grand lecteur et observateur de son temps, Liszt écrit également un nombre impressionnant de lettres. Sa correspondance reste un corpus largement étudié aujourd’hui et elle a assuré l’un des axes de…
Entraînement auditif et musical chez l'enfant sourd profond : effets sur la perception auditive et effets de transferts
2012
This thesis focuses on the auditory training and auditory skill development of congenitally profoundly deaf children. It aims to evaluate, not only the effects of auditory training/auditory skill development on general auditory performances, but also the transfer effects on speech perception and development. An extended period of auditory deprivation leads to major difficulties in reception and speech production, cognitive difficulties, and also disrupts the maturation of central auditory pathways which limit the effects of hearing loss treatment in restoring sound transmission (cochlear implants or hearing aids). It is therefore necessary to teach children how to actively listen and to dev…
