¿Por qué América Latina, tierra fértil para la creatividad en políticas de ciencia, tecnología e innovación, tiene limitados logros en este campo? ¿Qué explica esta divergencia entre ideas y realizaciones en la región? Este libro explora las raíces históricas de ese desencuentro y plantea cómo superarlo. Un acucioso análisis de diseño e implementación de políticas de ciencia, tecnología e innovación en la segunda mitad del siglo 20, una revisión de los avances en el primer decenio del siglo 21 y una descripción de los desafíos futuros hacen de este texto una referencia indispensable para los interesados en el desarrollo de América Latina.

Reliability is one of the most important quality characteristics of components, products, and large and complex systems-but it takes a significant amount of time and resources to bring reliability to fruition. Thoroughly classroom- and industry-tested, this book helps ensure that engineers see reliability success with every product they design, test, and manufacture. Divided into three parts, Reliability Engineering, Second Edition handily describes the theories and their practical uses while presenting readers with real-world examples and problems to solve. Part I focuses on system reliability estimation for time independent and failure dependent models, helping engineers create a reliable design. Part II aids the reader in assembling necessary components and configuring them to achieve desired reliability objectives, conducting reliability tests on components, and using field data from similar components. Part III follows what happens once a product is produced and sold, how the manufacturer must ensure its reliability objectives by providing preventive and scheduled maintenance and warranty policies. This Second Edition includes in-depth and enhanced chapter coverage of: Reliability and Hazard Functions System Reliability Evaluation Time- and Failure-Dependent Reliability Estimation Methods of the Parameters of Failure-Time Distributions Parametric Reliability Models Models for Accelerated Life Testing Renewal Processes and Expected Number of Failures Preventive Maintenance and Inspection Warranty Models Case Studies A comprehensive reference for practitioners and professionals in quality and reliability engineering, Reliability Engineering can also be used for senior undergraduate or graduate courses in industrial and systems, mechanical, and electrical engineering programs.

Fundamentals of Structural Engineering provides a balanced, seamless treatment of both classic, analytic methods and contemporary, computer-based techniques for conceptualizing and designing a structure. The book''s principle goal is to foster an intuitive understanding of structural behavior based on problem solving experience for students of civil engineering and architecture who have been exposed to the basic concepts of engineering mechanics and mechanics of materials. Distinct from many undergraduate textbooks focused mainly on either teaching manual analysis methods and applying them to simple, idealized structures-an approach based on the premise that intuition about structural behavior is developed as one works through the manual computations which, at times, may seem exhaustive, or reformulating structural analysis methods in terms of matrix notation-an approach that provides the basis for developing and understanding computer software codes, but does not contribute toward developing intuition about structural behavior. The authors of this text recognize the notion that engineers reason about behavior using simple models and intuition they acquire through problem solving. The approach adopted in this text develops this type of intuition through by presenting extensive, realistic problems and case studies together with computer simulation, allowing rapid exploration how a structure responds to changes in geometry and physical parameters. The integrated approach employed in Fundamentals of Structural Engineering offers comprehensive preparation for students and authoritative reference for practitioners of structural engineering.

Engineers solve problems,ÿand work onÿemerging challenges inÿa wide range of areas important to improving quality of life; areas likeÿsustainable energy, access to clean water, andÿimproved communications and health care technologies.ÿ Kosky et. al. explore the world of engineering by introducing the reader to what engineers do, the fundamental principles that form the basis of their work, and how they apply that knowledgeÿwithin a structured design process.ÿÿThe three part organization of the text reinforces theseÿareas, making this an ideal introduction for anyone interested in exploring the various fields of engineering and learning how engineers work to solve problems.
