La comtesse de Ségur est ici resituée dans le contexte de l’édition spécialisée du xixe siècle, dans un environnement thématique et moral qui n’exclut pas une originalité profonde et paradoxale. En effet, plusieurs principes élémentaires semblent gouverner son oeuvre : le féminin, le religieux, l’aristocratique. Mais ces principes sont toujours illustrés d’une manière équivoque. La comtesse de Ségur résiste donc aux analyses de contenu, et son « message », quelquefois énigmatique, s’oppose même aux engagements officiels de son entourage ultramontaniste. L’ancrage aristocratique est toujours perturbé, mêlé à des valeurs « bourgeoises », tandis que certains textes manifestent une attirance pour la pauvreté, pauvreté de biens ou d’esprit. Cette complexité, qui requiert une sorte d’humilité de la part du lecteur le plus savant, permet de comprendre pourquoi ces livres, ne s’adressant pas aux enfants d’une classe particulière, conservent aujourd’hui leur puissance d’attraction, et pourquoi, ils n’ont cessé de susciter un intérêt critique. Au-delà de ce cas particulier, il s’agit donc de poser des questions qui touchent à la lecture littéraire, et à l’excès d’interprétation qui caractérise quelquefois notre modernité. En dépit de son statut inférieur, ou bien plutôt grâce à celui-ci, la littérature enfantine favorise un tel questionnement qui ne peut manquer de s’appliquer à toute la Littérature.Children's stories, FrenchHistory and criticismChildrenBooks and readingFrancehistoirelittérature pour la jeunesselittérature françaiseinterprétationcritiqueenfanceFranceœuvre littéraireChildren's stories, FrenchHistory and criticism.ChildrenBooks and reading843/.8Marcoin Francis532663FR-FrMaCLEBOOK9910348260003321La comtesse de Ségur, ou, Le bonheur immobile2861618UNINA05224nam 22007455 450 991029960890332120200705150358.03-319-15747-710.1007/978-3-319-15747-4(CKB)3710000000375615(EBL)1997872(SSID)ssj0001465354(PQKBManifestationID)11967625(PQKBTitleCode)TC0001465354(PQKBWorkID)11470717(PQKB)11464334(DE-He213)978-3-319-15747-4(MiAaPQ)EBC1997872(PPN)184895693(EXLCZ)99371000000037561520150309d2015 u| 0engur|n|---|||||txtccrAnalysis and Control of Oilwell Drilling Vibrations A Time-Delay Systems Approach /by Martha Belem Saldivar Márquez, Islam Boussaada, Hugues Mounier, Silviu-Iulian Niculescu1st ed. 2015.Cham :Springer International Publishing :Imprint: Springer,2015.1 online resource (294 p.)Advances in Industrial Control,1430-9491Description based upon print version of record.3-319-15746-9 Includes bibliographical references and index.From the Contents: Introduction -- Part I Modelling -- An Overview of Drillstring Models -- Bit–Rock Frictional Interface -- Comprehensive Modelling of a Vertical Oilwell Drilling System -- Part II Analysis -- Neural-Type Time-Delay Systems: Theoretical Background -- Part III Control -- Field Observations and Empirical Drilling Control -- Low-Order Controllers -- Flatness-Based Control of Drilling Vibrations.This book reports the results of exhaustive research work on modeling and control of vertical oilwell drilling systems. It is focused on the analysis of the system-dynamic response and the elimination of the most damaging drillstring vibration modes affecting overall perforation performance: stick-slip (torsional vibration) and bit-bounce (axial vibration). The text is organized in three parts. The first part, Modeling, presents lumped- and distributed-parameter models that allow the dynamic behavior of the drillstring to be characterized; a comprehensive mathematical model taking into account mechanical and electric components of the overall drilling system is also provided. The distributed nature of the system is accommodated by considering a system of wave equations subject to nonlinear boundary conditions; this model is transformed into a pair of neutral-type time-delay equations which can overcome the complexity involved in the analysis and simulation of the partial differential equation model. The second part, Analysis, is devoted to the study of the response of the system described by the time-delay model; important properties useful for analyzing system stability are investigated and frequency- and time-domain techniques are reviewed. Part III, Control, concerns the design of stabilizing control laws aimed at eliminating undesirable drilling vibrations; diverse control techniques based on infinite--dimensional system representations are designed and evaluated. The control proposals are shown to be effective in suppressing stick-slip and bit-bounce so that a considerable improvement of the overall drilling performance can be achieved. This self-contained book provides operational guidelines to avoid drilling vibrations. Furthermore, since the modeling and control techniques presented here can be generalized to treat diverse engineering problems, it constitutes a useful resource to researchers working on control and its engineering application in oilwell drilling.Advances in Industrial Control,1430-9491Fossil fuelsAutomatic controlVibrationDynamicsDynamicsFossil Fuels (incl.
