Impacts of climate change on water availability in Burgundy : quantitative and qualitative aspects
2016
Numerous studies dealing with climate change impacts on water ressources have been done at global scale, but the moderated size watersheds scale is less studied. The Burgundy region is located over several hydrographical basins (Seine, Loire and Rhône river), and provides a great diversity of hydrogeological and climate contexts. For these reasons, impacts of climate change on water resources are expected to be very different in space, and require an entire hydroclimatic modelling chain at local scale to be assessed. The main objective of this thesis consisted of the implementation of a modelling tool at the moderated-size watersheds scale of Burgundy. In this way, several watersheds and tw…

Apport d'un formalisme psychologique à la modélisation des préférences individuelles. Application aux choix d'itinéraires pédestres
2007
With the increasing need for a sustainable mobility, pedestrian movement analysis lately increased. In an attempt to get a more detailed knowledge of urban pedestrian movement, we intend to model the pedestrian's route choices. Our first approach is based on simple economic models, the discrete choice models. A psychological theory is added in the process in order to improve the pedestrian behaviour simulation. Results show that psychological formalisms are useful for individual choices' modelling. For this reason they could be used more systematically in the framework of urban mobility
Aspects typo-chronologiques et archéométriques de la céramique africaine sur le territoire de Cignana (Naro, AG, Sicile)
2017
Ce projet de recherche se fonde sur une étude typologique et archéométrique des matériaux d’époque romaine-impériale collectés pendant les prospections, surtout les céramiques africaines importées en Sicile entre la fin du Ier et le VIIe siècle apr. J.C. On ne va pas se concentrer sur une seule classe de céramique mais on va analyser globalement tous les objets manufacturés (amphores, sigillées, vaisselles culinaires, communes, lampes) en adoptant une approche diachronique correspondant à l’entière période de circulation de ces céramiques. L’objectif est de reconstruire les contacts économiques entre les deux provinces et individualiser l’origine des différentes productions. Nous allons ess…
Integrable systems, Frobenius manifolds and cohomological field theories
2022
In this dissertation, we study the underlying geometry of integrable systems, in particular tausymmetric bi-Hamiltonian hierarchies of evolutionary PDEs and differential-difference equations.First, we explore the close connection between the realms of integrable systems and algebraic geometry by giving a new proof of the Witten conjecture, which constructs the string taufunction of the Korteweg-de Vries hierarchy via intersection theory of the moduli spaces of stable curves with marked points. This novel proof is based on the geometry of double ramification cycles, tautological classes whose behavior under pullbacks of the forgetful and gluing maps facilitate the computation of intersection…

Diversity and phylogeography of Southern Ocean sea stars (Asteroidea)
2019
How is life distributed on the Southern Ocean sea floor? How can we explain species distribution patterns, their origin and the underpinning drivers? These questions are central to macroecological studies, especially in regions facing fast environmental changes. The main objective of this thesis was to describe and characterise distribution patterns of sea stars species (Echinodermata: Asteroidea) with regards to reproductive strategy (i.e. brooding versus broadcasting), a key life history trait for species dispersal. I tested whether contrasting dispersal abilities between direct developers (brooders) and species with pelagic larvae in their development (broadcasters) result in distinct di…
Les graphes paysagers pour la modélisation et la gestion des pullulations de campagnols terrestres.
2016
International audience; Les prairies d’Auvergne et de Franche-Comté sont régulièrement envahies par un rongeur, le campagnol terrestre. Le projet CAMPAGRAPHE vise à fournir un appui pour la mise en place d’un dispositif agro-écologique limitant sa diffusion grâce à une modélisation des réseaux de prairies.Le graphe obtenu permet de localiser des actions de terrain et orienter le suivi des populations.
EVASPA (EVapotranspiration Assessment from SPAce) tool: an overview
2013
International audience; Evapotranspiration (ET) is a fundamental variable of the hydrological cycle and its estimation is required for irrigation management, water resources planning and environmental studies. Remote sensing provides spatially distributed cost-effective information for ET maps production at regional scale. We have developed EVASPA too for mapping ET from remote sensing data at spatial and temporal scales relevant to hydrological or agronomica studies. EVASPA includes several algorithms for estimating evapotranspiration and various equations for estimating the required input information (net radiation, ground heat flux, evaporative fraction…), which provides a way to assess …
Le site du monastère Saint-Pierre d'Ilovik (îlot Saint-Pierre, Croatie) : première étude archéologique du bâti
2011
Ce monastère, très mal connu, est situé dans une petite crique de l’îlot Saint-Pierre faisant face à l’île d’Ilovik, immédiatement au sud de Lošinj. L’îlot Saint-Pierre était occupé durant l’Antiquité par une grande villa, dont des vestiges (murs et sols) sont encore visibles sur la grève de la façade occidentale (fig. 1). Fig. 1 – Saint-Pierre d’Ilovik, sondages dans les enduits du mur sud : découvertes des baies (cl. S. Bully). Les photographies aériennes révèlent également plusieurs orga...
