Many process control books focus on control design techniques, taking the construction of a process model for granted. Process Modelling for Control concentrates on the modelling steps underlying a successful design, answering questions like: How should I carry out the identification of my process in order to obtain a good model? How can I assess the quality of a model with a view to using it in control design? How can I ensure that a controller will stabilise a real process and achieve a pre-specified level of performance before implementation? What is the most efficient method of order reduction to facilitate the implementation of high-order controllers? Different tools, namely system identification, model/controller validation and order reduction are studied in a framework with a common basis: closed-loop identification with a controller that is close to optimal will deliver models with bias and variance errors ideally tuned for control design. As a result, rules are derived, applying to all the methods, that provide the practitioner with a clear way forward despite the apparently unconnected nature of the modelling tools. Detailed worked examples, representative of various industrial applications, are given: control of a mechanically flexible structure; a chemical process; and a nuclear power plant. Process Modelling for Control uses mathematics of an intermediate level convenient to researchers with an interest in real applications and to practising control engineers interested in control theory. It will enable working control engineers to improve their methods and will provide academics and graduate students with an all-round view of recent results in modelling for control. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

L’ambition est double. Analyser d’abord l’inscription de la mort dans une œuvre de poésie et en dresser le paysage. Ensuite montrer comment la totalité de cette œuvre s’organise en fonction de ce point de vue majeur, la mort, et sortir ainsi du lieu commun énoncé quant à l’œuvre de Jouve, laquelle n’aurait d’autre pivot que le sexe. De cela, il découle une « histoire » de la mort, avec son théâtre d’ombres, et ses coulisses, ses personnages et ses « lustres », ses « machines » et ses décors, une « histoire de la mort » dans l’œuvre qui est histoire de l’œuvre poétique même.

Au XIIIe siècle, les pouvoirs médiévaux s’assimilent un ensemble de techniques rhétoriques élaborées au Moyen Âge central sous le nom d’ars dictaminis La cour sicilienne de l’empereur Frédéric II est, sous l’impulsion de Pierre de la Vigne, un laboratoire privilégié dans le processus de perfectionnement de cette prose politique rythmée. Alors que s’effondre la dynastie souabe, les héritiers de sa chancellerie transmettent à la postérité les textes les plus représentatifs de cette rhétorique impériale en créant une collection de dictamina : les Lettres de Pierre de la Vigne, auquel ce style emphatique et voilé d’obscurités métaphoriques sera désormais associé. Ce livre étudie une étape décisive de la formation du langage politique européen à partir de l’histoire des Lettres, envisagée dans ses différents aspects, de la création mystérieuse de la collection jusqu’à sa transformation en objet historique, en passant par l’analyse du milieu, de l’idéologie et des techniques rhétoriques des créateurs de ses textes, de leur impact et de leur interprétation contradictoire dans la société du XIIIe siècle. Il montre les procédures mises en œuvre par les notaires ultérieurs pour exploiter ce « miroir rhétorique » et son poids dans la transformation générale du langage étatique européen au cours d’un long XIVe siècle (1270-1420), de l’Angleterre à la Bohême, de la France à l’Italie. En explorant ce continent du dictamen politique ultérieurement recouvert par la vague humaniste, on tente ainsi de progresser, sur la piste de Kantorowicz, dans la reconstitution des liens mystérieux unissant idéologie linguistique, droit et construction étatique à l’automne du Moyen Âge.

L’histoire des techniques et des artisanats de la Grèce antique a laissé jusqu'ici peu de place à un matériau comme le cuir, sous prétexte du manque de sources textuelles et iconographiques ou de leur caractère trop allusif, et parce que les objets réalisés en peau, fourrure et cuir n’ont que trop rarement été retrouvés en fouille. Pourtant, la collecte des sources testimoniales (images, textes littéraires, épigraphiques, papyrologiques) – menée non sans élargir le champ de la recherche à certains auteurs latins et tardifs, comme les lexicographes – et, dans une proportion bien moindre, des don- nées de terrain, articulée à une modélisation technique de la fabrication du matériau, permet de renouveler quelque peu l’approche et de préciser ce que furent cet artisanat et les usages des peaux et du cuir en Grèce antique, bien que la somme réunie ici suscite également un grand nombre de questions et de pistes qui restent non résolues. Notre enquête tente ainsi, avec toute la prudence et la modestie que doit garder le chercheur qui travaille sur les mondes antiques, de dresser le bilan de nos connaissances quant aux étapes de fabrication de la matière première en matériau, fabrication relevant d’un savoir spécifique mais qui devait trouver des degrés de réalisation très variables. Nous passons ensuite en revue l’utilisation des peaux, fourrures et cuir, des emplois quotidiens les plus attendus aux cas les plus particuliers. Nous envisageons enfin l'organisation des « métiers du cuir », depuis l'approvisionnement en peaux brutes jusqu’aux opérations de cordonnerie, et le jugement porté sur ces activités au IVe siècle av. J.-C. à Athènes, période la mieux documentée sur la question.

De création récente, les sociétés de la Caraïbe sont issues de la colonisation des Amériques qui s'accompagna de l'extermination de populations amérindiennes, de la transplantation et de l'esclavage de populations d'origine africaine, puis de différentes vagues de migration. Ces sociétés ont su pourtant élaborer des systèmes originaux de représentations du corps et de la maladie qui rendent compte de leur inscription sur un sol nouveau et expriment de nouveaux rapports sociaux. Cet ouvrage étudie plus particulièrement la manière dont, à la Guadeloupe, les savoirs concernant la santé et la maladie constituent un ensemble structuré de représentations et de pratiques qui renvoient à des cosmogonies bien définies. En recourant aux méthodologies de l'ethnobotanique et de l'ethnomédecine, en faisant appel à la cartographie, l'auteur analyse la pharmacopée à base de plantes médicinales et propose une lecture originale du paysage des jardins de case. L'organisation de ces derniers reflète en effet la vision du monde de ses occupants, et matérialise dans l'espace le bien-être et les maux du corps, tout comme les relations avec l'entourage et les morts. On découvre ainsi comment, dans une situation de pluralisme médical et dans un milieu pluriethnique, des thérapeutes et des patients passent d'un système médical à l'autre sans pour autant abandonner leur vision du monde.

The notion of an operad supplies both a conceptual and effective device to handle a variety of algebraic structures in various situations. Operads were introduced 40 years ago in algebraic topology in order to model the structure of iterated loop spaces. Since then, operads have been used fruitfully in many fields of mathematics and physics. This monograph begins with a review of the basis of operad theory. The main purpose is to study structures of modules over operads as a new device to model functors between categories of algebras as effectively as operads model categories of algebras.

This book presents several fundamental questions in mathematical biology such as Turing instability, pattern formation, reaction-diffusion systems, invasion waves and Fokker-Planck equations. These are classical modeling tools for mathematical biology with applications to ecology and population dynamics, the neurosciences, enzymatic reactions, chemotaxis, invasion waves etc. The book presents these aspects from a mathematical perspective, with the aim of identifying those qualitative properties of the models that are relevant for biological applications. To do so, it uncovers the mechanisms at work behind Turing instability, pattern formation and invasion waves. This involves several mathematical tools, such as stability and instability analysis, blow-up in finite time, asymptotic methods and relative entropy properties. Given the content presented, the book is well suited as a textbook for master-level coursework.

From lobbyists such as Jack Abramoff, to corporate executives, like Enron's Kenneth Lay and Jeffrey Skilling, recent scandals dealing with politics and government have focused only on men at the top. But do these high-profile men accurately represent the gendered make up of corporate-government in the United States? In this first in-depth look at the changing face of corporate lobbying, Denise Benoit shows how women who have historically worked mostly in policy areas relating to "women's issues" such as welfare, family, and health have become increasingly influential as corporate lobbyists, specializing in what used to be considered "masculine" policy, such as taxes and defense. Benoit finds that this new crop of female lobbyists mobilize both masculinity and femininity in ways that create and maintain trusting, open, and strong relations with those in government, and at the same time help corporations to save and earn billions of dollars. While the media focuses on the dubious behaviors of men at the top of business and government, this book shows that female corporate lobbyists are indeed one of the best kept secrets in Washington.
