Relay feedback has attracted considerable research attention for more than a century but there has been no recent summary of the many newly-developed tools and results now available for this important area as a whole, those that have been published tending to focus on one process or controller type only. Relay Feedback is divided into three parts, the first of which is devoted to the analysis of relay feedback systems within a general setting with information on: existence of solutions; existence of limit cycles; local and global stability of limit cycles; limit cycles with more than two switchings per period; plants with time delay; relays with asymmetric hysteresis. The second part, on the improvement of process identification shows the reader how to: modify a standard relay to provide better excitation of a process at a number of important frequencies; devise new algorithms designed to make better use of information from relay feedback tests. The book's third part is a presentation of recent developments in control design providing: a unified framework for the design of internal-model, proportional-integral-derivative or general-single-loop controllers for SISO or MIMO systems with or without time delays; characterisation of time delays and non-minimum phase zeros for closed-loop systems. Relay Feedback presents a comprehensive, up-to-date and detailed treatment of relay feedback theory, the use of relay feedback for process identification and the use of identified models for general control design in a single volume. The work assumes only knowledge of linear system theory on the part of the reader and should therefore be of use to graduate students and practising engineers as well as to researchers.

Immaginate di scoprire che tutto ciò che sapete della vostra infanzia è falso. È quanto accade a Maia: cresciuta con genitori adottivi che l’hanno colmata d’amore, non si è mai fatta troppe domande sulle sue origini. Anzi, non ha mai voluto saperne nulla. Ma ora Maia è incinta e, per proteggere il futuro della bambina che porta in grembo, ha bisogno di conoscere il proprio passato. Nella soffitta di casa c’è un baule che si è sempre guardata dall’aprire. Adesso, però, decide di farlo. Al suo interno, trova fogli scarabocchiati, articoli e qualche fotografia. Sono i primi indizi che deve mettere insieme, i tasselli del grande puzzle della sua infanzia. Ci sono porte che, una volta aperte, non possono più essere richiuse..

This book is the third in a series of lectures of the S´ eminaire Poincar´ e,whichis directed towards a large audience of physicists and of mathematicians. The goal of this seminar is to provide up to date information about general topics of great interest in physics. Both the theoretical and experimental aspects are covered, with some historical background. Inspired by the Bourbaki seminar in mathematics in its organization, hence nicknamed Bourbaphi, this Poincar´ e Seminar is held twice a year at the Institut Henri Poincar´ ein Paris,with contri- tions prepared in advance. A particular care is devoted to the pedagogical nature of the presentation so as to ful?ll the goal of being readable by a large audience of scientists. ThisvolumecontainsthesixthsuchSeminar,heldin2004.Itisdevotedtothe Quantum Hall E?ect. After a historical and general presentation by Nobel prize Klaus von Klitzing, discoverer of this e?ect, the volume proceeds with reviews on the mathematics and physics of both the integer and fractional case, and includes up to date presentations of the tunneling and metrology experiments related to the Quantum Hall E?ect. We hopethat the publicationof this serieswill servethe community of phy- cists and mathematicians at professional or graduate student level. ´ We thank the Commissariat `alEnergie Atomique (Division des Sciences de laMati` ere),theCentreNationaldelaRechercheScienti?que(SciencesPhysiqueet Math´ ematiques), and the Daniel Iagolnitzer Foundation for sponsoring the Se- nar. Special thanks are due to Chantal Delongeas for the preparation of the m- uscript.

Until the publication of the first edition of 'Star Maps,' books were either general histories of astronomy using examples of antiquarian celestial maps as illustrations, or catalogs of celestial atlases that failed to trace the flow of sky map development over time.

Thalia Fountas è una giovane soprano italo-greca, una donna determinata, che non si ferma mai. E allora perché, a un certo punto della sua vita e della sua carriera, le sembra di non riuscire più a cantare? Cosa si è rotto dentro di lei quella sera, a Monaco di Baviera, quando, in abito di scena, sfiorando il suo braccialetto portafortuna, ha capito di sentirsi estremamente sola? Strani sogni iniziano a tormentarla. Una casa bianca persa nel mare, ulivi, grandi distese di sabbia e una ragazza misteriosa che le somiglia. Thalia riconosce quei muri. La casa greca, sull’isola di Zante, appartenuta ai suoi nonni, morti da anni. Tutto la spinge verso quel luogo incantevole, traboccante di segreti..
