Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

This monograph and translation from the Russian describes in detail and comments on the fundamentals of metrology. The basic concepts of metrology, the principles of the International System of Units SI, the theory of measurement uncertainty, the new methodology of estimation of measurement accuracy on the basis of the uncertainty concept, as well as the methods for processing measurement results and estimating their uncertainty are discussed from the modern position. It is shown that the uncertainty concept is compatible with the classical theory of accuracy. The theory of random uncertainties is supplemented with their most general description on the basis of generalized normal distribution; the instrumental systematic errors are presented in connection with the methodology of normalization of the metrological characteristics of measuring instruments. The information about modern systems of traceability is given. All discussed theoretical principles and calculation methods are illustrated with examples.

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.

To survive and thrive in the competition, firms have strived to achieve greater supply chain collaboration to leverage the resources and knowledge of suppliers and customers. Internet based technologies, particularly interorganizational systems, further extend the firms'' opportunities to strengthen their supply chain partnerships and share real-time information to optimize their operations. "Supply Chain Collaboration: Roles of Interorganizational Systems, Trust, and Collaborative Culture" explores the nature and characteristics, antecedents, and consequences of supply chain collaboration from multiple theoretical perspectives. "Supply Chain Collaboration: Roles of Interorganizational Systems, Trust, and Collaborative Culture" conceptualizes supply chain collaboration as seven interconnecting elements including information sharing, incentive alignment, goal congruence, decision synchronization, resource sharing, as well as communication and joint knowledge creation. These seven components define the occurrence of collaborative efforts and allow us to explain supply chain collaboration more precisely. Collaborative advantages are also divided into five components to capture the joint competitive advantages and benefits among supply chain partners. The definitions and measures developed here examine some central issue surrounding supply chain development but this is also followed up with real-life managerial practicalities. This balance of theory and practical application makes "Supply Chain Collaboration: Roles of Interorganizational Systems, Trust, and Collaborative Culture" a strong resource for industry practitioners and researchers alike.

El tratado de Procedimientos generales de Construcción tiene por objeto el estudio de las reglas técnicas y métodos de trabajo que condicionan la ejecución de las obras públicas. Este Tratado está también estrechamente relacionado con los cursos de Derecho administrativo y exige, de una parte, el estudio y la redacción de los proyectos, y de obra la preparación de presupuestos y liquidaciones, algunas de las cuales toman a veces un carácter contencioso.

La estratégica ubicación de Zaragoza dentro de la península ibérica, como punto de enlace entre la meseta y las regiones mediterráneas y pirenaicas ha permitido -primeramente con los aeródromos (Valdespartera, Sanjurjo y Valenzuela) y posteriormente con la construccion del aeropuerto- que su desarrollo haya estado intimamente ligado a la aviacion como nudo de comunicaciones con el resto de la nacion. Muchos han sido los avatares, no exentos de anecdotas, que desde los inicios de la aviacion, alla por el año 1910, han acontecido en la historia de su aeropuerto, siempre tan ligada a la de su base aerea. Su crecimiento ha sido pausado, pero continuo, centrado fundamentalmente en sus conexiones con Barcelona y Madrid. Poco a poco con el establecimiento de nuevas compañias aereas, el impulso economico que supuso para toda la region la ubicacion en Zaragoza de la Exposicion Internacional de 2008 y el desarrollo del transporte de mercancias por via aerea, han hecho que el futuro de este aeropuerto pueda verse con optimismo, gracias al apoyo y a la apuesta de Aena por esta infraestructura, asi como por el impulso que todas las autoridades y los ciudadanos de esta comunidad le prestan como importante motor economico de toda la region. El libro recoge toda una historia plagada de imagenes entrañables y datos interesantes que, sin duda, resultara de gran interes no solo para los amantes de la aviacion, sino tambien para todos los zaragozanos, ya que finalmente constituye una cronica de su propio devenir desde principios del pasado siglo a la actualidad.
