The classical ARMA models have limitations when applied to the field of financial and monetary economics. Financial time series present nonlinear dynamic characteristics and the ARCH models offer a more adaptive framework for this type of problem. This book surveys the recent work in this area from the perspective of statistical theory, financial models, and applications and will be of interest to theorists and practitioners. From the view point of statistical theory, ARCH models may be considered as specific nonlinear time series models which allow for an exhaustive study of the underlying dynamics. It is possible to reexamine a number of classical questions such as the random walk hypothesis, prediction interval building, presence of latent variables etc., and to test the validity of the previously studied results. There are two main categories of potential applications. One is testing several economic or financial theories concerning the stocks, bonds, and currencies markets, or studying the links between the short and long run. The second is related to the interventions of the banks on the markets, such as choice of optimal portfolios, hedging portfolios, values at risk, and the size and times of block trading.

The Renegades Trilogy continues, in this fiercely awaited second installment after the New York Times-bestselling Renegades by Marissa Meyer, author of the Lunar Chronicles. Now a New York Times Bestseller! Time is running out. Together, they can save the world. But they each other’s worst nightmare. Nova’s double life is about to get a lot more complicated: As Insomnia, she is a full-fledged member of the Renegades, a syndicate of powerful and beloved superheroes. She works with Adrian’s patrol unit to protect the weak and maintain order in Gatlon City. As Nightmare, she is an Anarchist - a group of of villains who are determined to destroy the Renegades. Nova wants vengeance against the so-called heroes who once failed her when she needed them most. But as Nova, her feelings for Adrian are deepening, despite the fact that he is the son of her sworn enemies and, unbeknownst to Nova, he has some dangerous secrets of his own. In this second installment of the Renegades trilogy, Nova, Adrian, and the rest of their crew – Ruby, Oscar, and Danna -- are faced with escalating crime in Gatlon City, while covert weapons and conflicting missions have Nova and Adrian questioning not only their beliefs about justice, but also the feelings they have for each other. The line between good and evil has been blurred, but what's clear to them both is that too much power could mean the end of their city – and the world – as they know it.

Les ponts en arc font actuellement face au double défi de protéger leur patrimoine et de rivaliser avec d'autres formes plus récentes de structures. La conservation des ponts en arc implique de multiples impératifs : une politique saine d'inspection et de suivi, des méthodes précises d'investigation, une évaluation fiable et un éventuel diagnostic, des moyens efficaces de maintenance, de réparation, de renforcement et d'élargissement. Pendant que des ouvrages existants sont réparés et revalorisés, de nouveaux ponts en arc, de -nies traditionnelles et à " l'échelle humaine ", continuent à se construire, en utilisant des matériaux et procédés améliorés et rentables, assurant longévité et respect de l'environnement. Au premier plan de cette continuité, les concepteurs des ponts en béton, dans les hémisphères Nord et Sud, s'efforcent avec succès de réaliser des portées en arc de plus en plus longues, frôlant les 400 mètres dans les années 1980. Récemment, sur d'autres sites spectaculaires, des records de portées ont été battus par trois ponts en arc respectivement en pierre, en béton, en tubes d'acier remplis de béton. Une telle avancée ne manquera pas d'inciter les ingénieurs à rechercher des formes d'arc encore plus audacieuses et élégantes. Sur le large éventail des thèmes proposés, de nombreux auteurs, de plus de vingt-cinq pays, ont apporté des contributions majeures rappelant que les ponts en arc n'ont rien perdu de leur actualité et que, malgré les leçons assimilées de leur prestigieux héritage, leur conception stimule toujours la créativité des ingénieurs et des architectes. Ces contributions sont réunies dans le présent volume édité à l'occasion de la Troisième Conférence internationale sur les Ponts en Arc, tenue à Paris en septembre 2001. Arch bridges face at present the double challenge of protecting their heritage and competing with other more recent structural forms. The conservation of the arch bridge heritage successively requires sound inspection and monitoring policies, accurate investigative methods, reliable assessment and eventual diagnosis, efficient means for maintenance, repair, strengthening and widening. While existing structures are being repaired and upgraded, new arch bridges, of traditional forms and on a "human scale", continue to be constructed, using improved and cost-effective materials and procedures, ensuring longevity and respect for the environment. In the forefront of this continuity, concrete bridge designers, in the northern and southern hemispheres, have successfully been striving for ever larger arch spans, closely approaching 400 m in the 1980's. Lately, at other spectacular sites, span records were beaten in three arch bridges respectively using stone, concrete and slender concrete-filled steel tubes. This breakthrough may encourage engineers to seek more daring and elegant forms of arch. On the broad spectrum of the suggested topics, numerous authors, from more than twenty-five countries, have recently offered major contributions, reminding that arch bridges have nothing lost of their appeal and that, for all the lessons learnt from their prestigious heritage, their design still simulates the creativity of engineers and architects. These contributions are put together in the present volume edited on the occasion of the Third International Arch Bridge Conference held in Paris in September 2001.
