This beautiful field guide offers orchid enthusiasts everything they need to know about what, where, and when to find wild orchids in the southeastern United States. With 285 color photos and detailed original drawings, it will delight both the new admirer and the long-time lover of these seductive flowering plants. Covering a region that includes eastern Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina, and northern Florida, as well as southeastern North Carolina, and southern Arkansas, the book presents all the information necessary to correctly identify 76 species of orchids, 4 varieties, 61 forms, and 13 hybrids. It includes some of the rarest species found in the United States as well as several new species and subspecific taxa that recently have been documented in this area but have never been described in book format. No existing field guide provides all available information for these states. Orchid identification presents even experienced botanists with a challenge. Paul Martin Brown, author of several successful orchid books for other U.S. regions, undertakes this task in a logical, easy-to-understand manner. The guide is designed for locating information easily while one foot is in the proverbial bog. Brown’s approach to the complex vocabulary of botanical taxonomy is clear and his explanation of botanical keys will aid the novice orchid hunter as well as the trained orchid professional. Created for identification in the field or anywhere live specimens are found, the key is not strictly technical. Its dependence on color and measurements has been kept to a minimum, allowing readers to use it without removing orchids from the wild. Supporting material addresses common questions about habitat, color forms, and hybrids and also clarifies the taxonomically confusing genera Spiranthes and Platanthera.

Ah ! La vie au Moyen âge, les chevaliers et les jolies dames aux longs chapeaux pointus... Attention, ce livre va vous donner un autre son de cloche. Les chevaliers n''étaient pas de braves et nobles guerriers qui détendaient les paysans, mais de grosses brutes tordues qui saccageaient les récoltes. Il y avait la guerre, la famine, la peste noire, les paysans avaient pour noms " gueux " ou " serfs ", vivaient dans des conditions déplorables et mouraient très jeunes. Les riches, eux, s''amusaient... Toutes ces choses et bien d''autres encore racontées avec beaucoup d''humour donneront au lecteur une vision réaliste de ce qu''était vraiment cette époque. L''Histoire n''a jamais été aussi horrible !

Filled the sparkling photography and beautiful illustrations, this guide to a classic North American flower covers 223 species, twenty-four subspecies, and 103 growth and color forms, arming readers with everything they need to know to track, identify, and classify this much-sought-after bud. (Biology & Natural History)

C''était le temps des héros horribles, des sauvages soldats de Sparte, des philosophes fous et des dieux très puissants qui mangeaient leurs propres enfants. C''était le temps où pour se préparer au mariage, les jeunes femmes devaient courir et danser nues dans les bois en faisant semblant d''être des ourses. C''était comme ça chez les Grecs. Toutes ces choses et bien d''autres encore racontées avec énormément d''humour donneront au lecteur une vision réaliste de ce qu''était vraiment la vie à l''époque. L''Histoire n''a jamais été aussi horrible !

Clinical economics is a new and evolving discipline that addresses the economic implications of changes in medical practice. As applied to cancer care, clinical economics assesses the costs and effectiveness of new cancer interventions and can be a valuable endpoint in selected clinical trials. Through the integration of economics into clinical evaluations, information can be developed that contributes to the decisions of patients, clinicians, health care managers, and policymakers as to the most effective allocation of cancer care resources.

Governments are increasingly constrained to examine the economic impacts of all the programmes they finance, but assessment methodologies pose problems. This publication examines these methodological problems and analyses the results of existing evaluation studies.

Describes several adaptive neural and fuzzy networks and introduces the associate memory class of systems. The Albus CMAC, the B-spline network and a class of fuzzy systems are described and analyzed. Their desirable features, such as local learning, are stressed and the algorithms are evaluated.

With increasing demands for high precision autonomous control over wide operating envelopes, conventional control engineering approaches are unable to adequately deal with system complexity, nonlinearities, spatial and temporal parameter variations, and with uncertainty. Intelligent Control or self-organising/learning control is a new emerging discipline that is designed to deal with problems. Rather than being model based, it is experiential based. Intelligent Control is the amalgam of the disciplines of Artificial Intelligence, Systems Theory and Operations Research. It uses most recent experiences or evidence to improve its performance through a variety of learning schemas, that for practical implementation must demonstrate rapid learning convergence, be temporally stable, be robust to parameter changes and internal and external disturbances. It is shown in this book that a wide class of fuzzy logic and neural net based learning algorithms satisfy these conditions. It is demonstrated that this class of intelligent controllers is based upon a fixed nonlinear mapping of the input (sensor) vector, followed by an output layer linear mapping with coefficients that are updated by various first order learning laws. Under these conditions self-organising fuzzy logic controllers and neural net controllers have common learning attributes.A theme example of the navigation and control of an autonomous guided vehicle is included throughout, together with a series of bench examples to demonstrate this new theory and its applicability.
