Available in PDF, EPUB and Kindle. Book excerpt: LA MISE EN UVRE ET LE CONTROLE DES BIOPROCEDES NECESSITENT LA CONNAISSANCE DE L'EVOLUTION AU COURS DU TEMPS DE LA COMPOSITION DU MILIEU. DE PLUS LES PROCEDES METTANT EN UVRE DES ORGANISMES VIVANTS SONT CARACTERISES PAR DES PHENOMENES FORTEMENT NON LINEAIRES ET SOUVENT PEU PRECIS. L'OBJECTIF DE CE TRAVAIL EST LA CONCEPTION, LA MODELISATION, L'OBSERVATION ET LA COMMANDE D'UN REACTEUR CONTINU A MEMBRANE. DANS UN PREMIER TEMPS, ON DECRIT LA SOUCHE (LACTOBACILLUS CASEI SOUS ESPECE RHAMNOSUS), L'ULTRAFERMENTEUR ET LES METHODES D'ANALYSES. LE CHAPITRE SUIVANT TRAITE DE LA MODELISATION (STRUCTURE DU MODELE, IDENTIFICATION, VALIDATION) DU FERMENTEUR FONCTIONNANT EN MODE CONTINU. LA SYNTHESE ET LA MISE EN UVRE EXPERIMENTALE D'UN OBSERVATEUR NON LINEAIRE POUR L'ESTIMATION DE LA CONCENTRATION EN BIOMASSE DANS LE REACTEUR EST DECRITE. LE DERNIER CHAPITRE EST CONSACRE A LA COMMANDE NON LINEAIRE DU BIOREACTEUR. ON MONTRE QUE LE CONTROLE DU FERMENTEUR PAR UNE ALIMENTATION EN ACIDE LACTIQUE ENGENDRE UNE STRUCTURE PERMETTANT L'ELABORATION D'UNE COMMANDE PAR DIFFEOMORPHISME ET BOUCLAGE STATIQUE. LE SYSTEME DEVIENT TOTALEMENT LINEARISABLE

Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse concerne la commande des systèmes dont la dynamique peut être convenablement décrite par une approche multimodèle à partir d'un étude d'affinement des performances d'un système de commande adaptative avec modèle de référence. Trois approches de commande multimodèle ont été proposées. La première approche est basée sur la commande avec modèle de référence sur la sortie. Une validation expérimentale réussie a été effectuée sur un réacteur chimique. La seconde approche est basée sur la commande prédictive avec modèle de référence sur l'état partiel. Des résultats de simulation, obtenus à partir d'un modèle physique d'un bioréacteur, ont montré que les performances du système de commande multimodèle sont semblables à celles obtenues par un système de commande non linéaire appropriée du type backstepping. La troisième approche est consacrée à la compensation des perturbations harmoniques dans le cas où la dynamique du système peut être raisonnablement décrite par un une famille de modèles linéaires invariants. La quatrième approche est basée sur une commande predictive multimodèle avec modèle de référence sur l'état partiel issue d'une synthèse LMI.

Book excerpt: L'application des techniques avancées d'observation et de commande non-linéaire dans le génie des procédés est le thème abordé dans cette thèse. Ces applications sont orientées essentiellement vers deux types de procédés couramment rencontrés dans l'industrie : les biorécateurs et les réacteurs de polymérisation. Une stratégie de commande non-linéaire à modèle interne et une autre à horizon glissant ont été développées. Ces deux stratégies ont comme même objectif la régulation de la concentration de nitrate dans un bioréacteur de dénitrification d'eaux usées. Leurs performances sont testées en simulation en utilisant un modèle mathématique du bioréacteur. Dans le cas des réacteurs de polymérisation, deux cas sont traités. Premièrement, on synthétise un observateur continu-discret pour l'estimation de paramètres variants dans le temps qui n'ont pas le modèle mathématique pour la présentation explicite de leurs dynamiques. Cet observateur a été validé expérimentalement. Deuxièmement, l'utilisation de l'observateur continu-discret avec des algorithmes de commande géométrique pour, d'une part, la poursuite de trajectoire de la température de transition vitreuse dans le cas d'une copolymérisation radicalaire en solution et d'une autre part, la régulation de la composition cumulée du copolymère dans le cas d'une copolymérisation radicalaire en solution.

Book excerpt: Cette these est consacree a la modelisation semiqualitative de bioprocedes en vue de leur conduite. Une analyse des differentes approches de modelisation montre les difficultes de prendre en compte dans un meme formalisme, toutes les connaissances quantitatives et qualitatives, generalement disponibles sur un procede que l'on cherche a commander. C'est pourquoi, une approche originale est proposee, appelee modelisation semiqualitative qui s'appuie sur un modele de connaissances dont les variables et parametres sont definis par des intervalles. Pour ces modeles semiqualitatifs, nous etudions leurs proprietes de simulation et prediction et plus particulierement, leur ajustement a partir de donnees experimentales. Nous montrons que des predictions a court terme, tout a fait pertinentes, pouvaient etre obtenues, qui font de ces modeles semiqualitatifs des outils interessants pour le developpement de systemes de conduite de bioprocedes

Available in PDF, EPUB and Kindle. Book excerpt: Optimal control is a branch of applied mathematics that engineers need in order to optimize the operation of systems and production processes. Its application to concrete examples is often considered to be difficult because it requires a large investment to master its subtleties. The purpose of Optimal Control in Bioprocesses is to provide a pedagogical perspective on the foundations of the theory and to support the reader in its application, first by using academic examples and then by using concrete examples in biotechnology. The book is thus divided into two parts, the first of which outlines the essential definitions and concepts necessary for the understanding of Pontryagin’s maximum principle – or PMP – while the second exposes applications specific to the world of bioprocesses. This book is unique in that it focuses on the arguments and geometric interpretations of the trajectories provided by the application of PMP.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with monitoring and control of biotechnological processes. Different methods are proposed which are based on the nonlinear structure of the process and do not require any a priori knowledge of the fermentation parameters. The theoretical stability and convergence properties of the proposed algorithms are analysed and their performances are illustrated by simulation results and, in many instances, by real life experiments. The concept of software sensors is introduced; these are algorithms based on the nonlinear model of the process and designed for on-line estimation of the biological variables and/or the fermentation parameters. In order to deal with process nonstationarities and parameter uncertainties, reference is made to adaptive estimation and control techniques.The book is the result of an intensive joint research effort by the authors during the last decade. It is intended as a graduate level text for students of bioengineering as well as a reference text for scientists and engineers involved in the design and optimization of bioprocesses.

Book excerpt: Invented by J. Monod, and independently by A. Novick and L. Szilard, in 1950, the chemostat is both a micro-organism culturing device and an abstracted ecosystem managed by a controlled nutrient flow. This book studies mathematical models of single species growth as well as competition models of multiple species by integrating recent work in theoretical ecology and population dynamics. Through a modeling approach, the hypotheses and conclusions drawn from the main mathematical results are analyzed and interpreted from a critical perspective. A large emphasis is placed on numerical simulations of which prudent use is advocated. The Chemostat is aimed at readers possessing degree-level mathematical knowledge and includes a detailed appendix of differential equations relating to specific notions and results used throughout this book.

Available in PDF, EPUB and Kindle. Book excerpt: Chipless RFID based on RF Encoding Particle: Realization, Coding and Reading System explores the field of chipless identification based on the RF Encoding Particle (REP). The book covers the possibility of collecting information remotely with RF waves (RFID) with totally passive tags without wire, batteries, and chips, and even printed on paper. Despite the many benefits of RFID, deployment is still hindered by several economic and technological factors. Among these barriers are the high cost of tags, lack of reliability and security in the information contained in the RFID chip, and how tags are 'recycled.' This book focuses on the development of chipless RFID tags, representing a new family of low cost tags. With this technology information is extracted from the electromagnetic response of the tag, which depends only on its geometry. Various solutions have been developed by the authors to increase the amount of information, reduce the surface of the tag, or improve the robustness of detection. Considerations such as realization using paper substrate, the development of a low cost detection system, and measurements in a real environment have been addressed for practical implementation. - Introduces the chipless RFID REP approach as compared to classical chipless RFID, RFID, and barcode technologies - Includes a demonstration of the practical and economic potential of chipless RFID technology, with detailed presentations and discussions of different test benches and comparisons - Presents in detail numerous examples of chipless tags that are able to tackle specific problems: sensitivity of detection, encoding density, robustness of detection, problem of tag orientation, tags and reader cost, and compliance with emission standards - Focuses on the development of chipless RFID tags, representing a new family of low cost tags

Available in PDF, EPUB and Kindle. Book excerpt: Digital traces, whether digitized (programs, notebooks, drawings, etc.) or born digital (emails, websites, video recordings, etc.), constitute a major challenge for the memory of the ephemeral performing arts. Digital technology transforms traces into data and, in doing so, opens them up to manipulation. This paradigm shift calls for a renewal of methodologies for writing the history of theater today, analyzing works and their creative process, and preserving performances. At the crossroads of performing arts studies, the history, digital humanities, conservation and archiving, these methodologies allow us to take into account what is generally dismissed, namely, digital traces that are considered too complex, too numerous, too fragile, of dubious authenticity, etc. With the analysis of Merce Cunningham’s digital traces as a guideline, and through many other examples, this book is intended for researchers and archivists, as well as artists and cultural institutions.

Book excerpt: The recent introduction of the “nano” dimension to pyrotechnics has made it possible to develop a new family of highly reactive substances: nanothermites. These have a chemical composition that is comparable to that of thermites at submillimeter or micrometric granulometry, but with a morphology having a much increased degree of homogeneity. This book discusses the methods of preparation of these energetic nanomaterials, their specific properties, and the different safety aspects inherent in their manipulation.

Book excerpt: The era of chemical and biological megadeath is upon us, and the potential of deadly biowarfare attacks from governments, militant independent groups, and even individuals is far greater than it has been at any time in the past. At this time, more than twenty-five countries are developing, or have stockpiles of chemical and biological weapons, in many cases in sufficient quantities to wipe out the entire population of the world. So far the danger of chemical and biological aggression has been little acknowledged, and, at least in America, little prepared for by federal and local government. Most terrorist threats and attacks are not widely reported in the mainstream media. Although information about the proliferation of man-made diseases is carefully suppressed by governments and the media they will be covered in the pages of this book. Not only is America unprepared and ignorant of what is happening, but the people in government and scientific professions who do know, who should be warning the American public about the dangers of chemical and biological terrorism, are instead doing their utmost to hide this information from us; information that is vital for our survival.The information that is contained in the pages of this book will not be measured or calculated to reassure people that everything is fine, when reassurance is the exact opposite of what is needed at this time. It may even give you nightmares when you realise the real circumstance that we are in. The information in the pages that follow will be the truth about the biowarfare threat to America.
