Configurations spatiales et hiérarchiques du peuplement antique : des indicateurs quantitatifs pour une confrontation interrégionale.
2011
The increase or decrease of the number of settlements is frequently used to assess the interactions between ancient societies and their environment. Beside this quantitative indicator, the pattern and the spatial extent of a settlement are crucial to estimate the " human pressure " on the environment. Within the ArchaeDyn program, several quantitative indicators have been developed to characterise the spatial and hierarchical structure of a settlements' scatter. The application of these indicators in four regions of Southern and Central Gaul shows the evolution of the spatial and hierarchical configurations of the settlement through phases of increasing and reducing rates of occupation.
Approche des groupes culturels et de leurs interactions entre Rhin et Rhône à la transition Bronze-Fer
2014
Cultural groups and their interactions follow from complex dynamics, delicate to grasp due to many unknown factors. However, it is still possible to define an approach to this problem with the use of elements from pre-established models, taking in consideration the different types of information offered by archaeological remains. The present analysis is part of a doctorat defended in April 2013 about cultural groups and exchanges dynamics, in a study area going from the Saône-Rhône confluence to the Mosel‘s mouth, from the 10th to the 8th centuries BC. More particularly, this work used metalwork types and deposit context as cultural indicators. The controntation of the results from the fact…

Approche multivariée des facteurs influençant le bilan de masse d’un glacier arctique
2015
National audience; L’Arctique est la zone géographique où la modification du climat au cours du XXIieme siècle sera la plus forte de la planète. La totalité de la cryosphère (banquise, glaciers, pergélisol, etc.) subira de profondes altérations qui se traduiront spatialement par des évolutions majeures. Les glaciers sont de bons indicateurs de ces changements, aussi bien à une échelle locale que globale, car leur dynamique est très sensible au climat. Cette étude porte sur un glacierdu Spitsberg où il a été observé que des conditions climatiques et nivologiques contrastées d’une année sur l’autre avaient des conséquences multiples, et parfois inattendues, sur les bilans de masse.

Infected persons by the fact of a public organism : is a fair compensation by the community realistic ? A graph-theory pproach
1999
The paper focuses on indirectly infected persons (persons infected by a person, infected by a person, etc., itself infected by a public organism, for AIDS, hepatitis C, etc.). It is assumed that fairness implies the national community to indemnify them. Graph theory is used to explain what is indirect infection. The concept of chains of infection, and their length is central. Re-infections are considered also because even individuals that are initially infected by another cause could become later indirectly infected by the public agent. The number of persons to be indemnified is larger than for direct infection, so the cost of compensation is higher, unless if compensation per capita is low…
Geostatistical computing of acoustic maps in the presence of barriers
2009
Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.
Association entre l’attirance pour le gras, le sucré et le salé et les fluctuations pondérales sur 4 ans
2016
Introduction et but de l’étude : Des études ont mis en évidence le lien entre l’attirance sensorielle pour le gras, le salé et le sucré et le statut pondéral, souvent évalué par une variation positive ou négative du poids. Les fluctuations pondérales sont également un indicateur pertinent bien que peu étudiées, puisque la multiplication de cycles de perte de poids puis de reprise, communément appelé « yo-yo pondéral » ou « fluctuation pondérales » pourrait avoir d’importantes répercussions sur la santé, tant au niveau physiologique qu’au niveau psychologique. L’objectif de cette étude était d’estimer l’association entre l’attirance pour le gras, le sucré et le salé et l’amplitude des fluctu…
