Résumé : La stratigraphie séquentielle vise à étudier, dans un cadre chronologique, la nature et la géométrie des sédiments fossiles en relation avec les variations du niveau marin. Elle permet de reconstituer l'histoire du remplissage des bassins sédimentaires, d'étudier les causes qui agissent sur la sédimentation, ou encore de prédire la disposition de roches qui ont pu piéger du pétrole. C'est une science jeune qui, en une trentaine d'années, a littéralement révolutionné la géologie sédimentaire. Dans la communauté scientifique - où elle a suscité de nombreux débats - elle passe encore pour hermétique ! Dans ce livre bref et très illustré, l'auteur entend démystifier la stratigraphie séquentielle. En suivant un fil historique, il en présente les faits d'observation et les notions de base, mais aussi les plus récentes évolutions. En offrant une lecture à plusieurs niveaux couplée à des exercices, ce manuel concerne en priorité les étudiants qui préparent les concours de l'Éducation nationale (CAPES et agrégation) et ceux qui fréquentent les filières spécialisées des sciences de la Terre. Il intéressera par ailleurs les enseignants-chercheurs des universités, les professeurs de l'enseignement secondaire et ceux des classes préparatoires.

Résumé : International audience
The published literature related to distributed parameter systems theoryis quite large, and it is not feasible in a single book to give a detailedreview on the wide historical development of all of it. Our choice of whatto cover was motivated by the following consideration. Since distributedparameter systems evolve in time and space, the research investigationson their analysis and control focus on considering the whole system domainfor any study. We feel strongly that within this research field, animportant consideration was missing; that of considering that the systemmay give raise to prescribed subdomains (regions) where one has toachieve an objective. This is the case of so many applications rangingfrom engineering to life sciences. For that reason, covering classical prerequisitein analysis and control areas, we have devoted the book to theextension of the classical distributed parameter results to regional ones.Students of mathematics do not come into contacts with distributedparameter systems during their classes. They are introduced to themwhen they start research and often they are influenced by the knowledgeand the advice of experimented scientists. This was our case at the verybeginning of these research investigations in the mid 70’s. We would liketo express our special thanks to many of them and mainly late ProfessorAnthony J. Pritchard (University of Warwick, GB) and late Professor J.L. Lions (College de France) who were so encouraging in front of our determinationin driving an academic carrier. We also express our thanksto our co-workers and research students. We wish to acknowledge thefeedback from all those who took courses based on various parts of thisbook.This book may be used by graduate students in mathematics, engineering,physics, and even by students from other fields such as life orenvironmental sciences. This book may also be used as an informationvi Avant-propossource for researchers and education professionals. We assume that thereaders already know the basic concepts of analysis and control of distributedparameter systems.

Résumé : International audience
This paper aims to demonstrate that the use of a modern tool, the GPS (Global PositioningSystem), can significantly improve our understanding of active faults and their seismic cycle. We focus on theNorth-Caribbean plate boundary, specifically in the Dominican Republic, and present some quantificationsof velocities that result from measurements that have been made possible by the instrumentation of the areaby a consortium of researchers from France, the USA and the Dominican Republic, since 1994. Then, wediscuss the velocities in terms of seismic potential of the regional major faults.
Cet article présente comment l'utilisation d'un outil moderne, le GPS (Global Positioning System) peut apporter des éléments significatifs dans la connaissance des failles actives et de leur cycle sismique. Nous nous intéressons ici à la frontière de plaque Nord-Caraibe, en République Dominicaine, et présentons des quantifications de vitesses de déplacement obtenues grâce à l'instrumentation de la zone depuis 1994 par un groupe de chercheurs français, états-uniens et dominicains. Les résultats sont ensuite discutés en termes d'aléas sismologiques des failles majeures.

Résumé : International audience
Drawing and handwriting are communicational skills that are fundamental in geopolitical, ideological and technological evolutions of all time. drawingand handwriting are still useful in defining innovative applications in numerous fields. In this regard, researchers have to solve new problems like those related to the manner in which drawing and handwriting become an efficient way to command various connected objects; or to validate graphomotor skills as evident and objective sources of data useful in the study of human beings, their capabilities and their limits from birth to decline.
