“If you are a serious user of UML, there is no other book quite like this one. I have been involved with the UML specification process for some time, but I still found myself learning things while reading through this book—especially on the changes and new capabilities that have come with UML.”

The latest version of the Unified Modeling Language—UML 2.0—has increased its capabilities as the standard notation for modeling software-intensive systems. Like most standards documents, however, the official UML specification is difficult to read and navigate. In addition, UML 2.0 is far more complex than previous versions, making a thorough reference book more essential than ever.

In this significantly updated and expanded edition of the definitive reference to the standard, James Rumbaugh, Ivar Jacobson, and Grady Booch—the UML’s creators—clearly and completely describe UML concepts, including major revisions to sequence diagrams, activity models, state machines, components, internal structure of classes and components, and profiles. Whether you are capturing requirements, developing software architectures, designing implementations, or trying to understand existing systems, this is the book for you.

Highlights include:

• Alphabetical dictionary of articles covering every UML concept
• Integrated summary of UML concepts by diagram type
• Two-color diagrams with extensive annotations in blue
• Thorough coverage of both semantics and notation, separated in each article for easy reference
• Further explanations of concepts whose meaning or purpose is obscure in the original specifications
• Discussion sections offering usage advice and additional insight into tricky concepts
• Notation summary, with references to individual articles
• A hyperlinked version of the book in Adobe Reader format on CD-ROM, an excellent resource for browsing or searching the text for specific information
• An enhanced online index available on the book’s web site allowing readers to quickly and easily search the entire text for specific topics

The result is an indispensable resource for anyone who needs to understand the inner workings of the industry standard modeling language.

Written by scientists, engineers, regulators, and lawyers, this timely and necessary reference work consolidates the latest Chromium (VI) literature, addressing issues of source, geochemistry, toxicity, treatment, legal cases, and recommendations.

1947. Una terrible amenaza venida de Oriente ha puesto en jaque a las principales potencias mundiales. La única esperanza de la humanidad está en las manos de Blake y Mortimer, una pareja de aventureros dispuestos a arriesgarlo todo por salvar la civilización, y el último invento de Mortimer: el misterioso Espadón.

Un dragón gigantesco causa estragos en los cielos de la capital nipona. Phillip Mortimer, inventor y aventurero, descubre enseguida la mano del hombre detrás de este fenómeno... y, cómo no, la de su némesis Olrik. Mortimer deberá aliarse al profesor Sato, el creador del dragón, para detener a su enemigo y devolver la paz a Japón.

1947. El Espadón es la última esperanza de la humanidad contra los ataques del Emperador Basam-Dandu, y Phillip Mortimer es el único que posee su secreto. Pero el inventor ha sido secuestrado y sólo su compañero Francis Blake se atreverá a adentrarse en la base enemiga para rescatarlo de las garras del coronel Olrik, el malvado sirviente del Emperador.

Una de las historias más clásicas de Blake y Mortimer ,que abre la colección dedicada a estos aventureros, por fin reeditada. La pareja de aventureros quedan atrapados en el Egipto contemporáneo, donde las maldiciones de las antiguas dinastías serán de la máxima actualidad.

Specifically focusing on fluid film, hydrodynamic, and elastohydrodynamic lubrication, this edition studies the most important principles of fluid film lubrication for the correct design of bearings, gears, and rolling operations, and for the prevention of friction and wear in engineering designs. It explains various theories, procedures, and equations for improved solutions to machining challenges. Providing more than 1120 display equations and an introductory section in each chapter, Fundamentals of Fluid Film Lubrication, Second Edition facilitates the analysis of any machine element that uses fluid film lubrication and strengthens understanding of critical design concepts.

Había unha vez unha porca vella e os seus tres fillos. Como non tiñan dabondo para vivir, mandounos a facer pola vida polo mundo adiante. O primeiro porquiño bateu cun home que levaba un saco cheo de palla, e díxolle:-Fai favor, arríame acó esa palla para que poida facer unha casa.Había unha vez tres porquiños pero só o irmán máis vello era traballador e asisado. Por iso fixo a súa casa de tixolo. O porquiño non lle tiña medo ó lobo. ¿E logo o lobo ía ser máis listo ca el?
