Vases "intrus" ? Vases "bâtards" ? De quelles influences témoignent les poteries retrouvées en milieu funéraire dans le bassin d'Yonne au début du Né…

2003

De profondes mutations économiques, sociales et culturelles marquent l’émergence du Néolithique moyen en Bassin parisien vers le milieu du Ve millénaire avant J.-C. Après les premiers temps de néolithisation, marqués par l’implantation dans les vallées des villages de paysans d’ascendance danubienne, l’évolution graduelle vers des sociétés plus hiérarchisées se manifeste par des phénomènes bien perceptibles : modifications dans l’économie, nouveautés technologiques, extension des surface occu...

Le complexe chasséen dans l’Yonne

2020

Je ne définirai pas ici le complexe chasséen, ce qui, par ailleurs, est fait avec brio dans le présent ouvrage. En 1864, sur la colline de Chassey étaient mis au jour les premiers tessons de ce qui deviendra, au milieu du xxe s., l’un des grands sites éponymes du Néolithique français. De nombreux préhistoriens se sont penchés sur Chassey parmi lesquels figurent J. Déchelette, V. G. Childe, J. Arnal, l’Abbé Joly et enfin, J.-P. Thevenot qui publie en 2005 sous peu la synthèse d’un siècle et de...

Le Néolithique du Morvan : état des connaissances

2012

The region of Morvan, in particular the granitic massif, forms a very large geographic area of which the prehistoric remains largely unknown. The situation regarding the zone lying between Morvan massif and the adjacent Serein, Arroux, A leine and Yonne valleys is very different. The lithic industry of several sites in Upper Morvan has demonstrated a first inhabitation during the Mesolithic and several hill sites occupied from the Middle Neolithic and during the Final Neolithic, including a probable enclosure on Mont Beuvray. Complementary studies in the A rroux Valley confirm a large expansion of the habitat and the erection of menhirs during the Middle Neolithic. Discoveries relating to t…

Combining hectometric and decametric satellite observations to provide near real time decametric FAPAR product

2017

Abstract A wide range of ecological, agricultural, hydrological and meteorological applications at local to regional scales requires decametric biophysical data. However, before the launch of SENTINEL-2A, only few decametric products are produced and most of them remain limited by the small number of available observations, mostly due to a moderate revisit frequency combined with cloud occurrence. Conversely, kilometric and hectometric biophysical products are now widely available with almost complete and continuous coverage, but the associated spatial resolution limits the application over heterogeneous landscapes. The objective of this study is to combine unfrequent decametric spatial res…

A simple algorithm to estimate evapotranspiration from DAIS data: Application to the DAISEX campaigns

2005

DOI:10.1016/j.jhydrol.2005.03.027; The knowledge of evapotranspiration is of great interest in many applications such as assessing irrigation water use. In this paper, a methodology is presented to estimate evapotranspiration using the surface energy balance model S-SEBI (Simplified Surface Energy Balance Index) and the evaporative fraction. The method is applicable under the assumptions of constant atmospheric conditions and sufficient wet and dry pixels over the image. The model uses remotely sensed parameters such as albedo, MSAVI (Modified Soil Adjusted Vegetation Index) and surface temperature and emissivity images. The methodology has been applied over the Barrax test site, located in…

Unified mapping of the dynamics of solitons in fiber-optic waveguides

2013

This thesis examines the dynamical behaviour of solitons which are affected, when entering a fiber-optic waveguide, by a slight distortion of profile as compared to the stationary profile in the guide. Our theoretical model combines the propagation equation of the electric field (Non-Linear Schrödinger Equation) and the system of equations of evolution of the physical parameters of the pulse (derived from the collective coordinates theory). We establish a general mapping which reveals an unsuspected diversity of dynamic behaviour around the stationary state of the pulse, in relation with the initial perturbation of the pulse's profile. This mapping establishes a classification of solitons i…
