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.

Human error plays a significant role in many accidents involving safety-critical systems, and it is now a standard requirement in both the US and Europe for Human Factors (HF) to be taken into account in system design and safety assessment. This book will be an essential guide for anyone who uses HF in their everyday work, providing them with consistent and ready-to-use procedures and methods that can be applied to real-life problems. The first part of the book looks at the theoretical framework, methods and techniques that the engineer or safety analyst needs to use when working on a HF-related project. The second part presents four case studies that show the reader how the above framework and guidelines work in practice. The case studies are based on real-life projects carried out by the author for a major European railway system, and in collaboration with international companies such as the International Civil Aviation Organisation, Volvo, Daimler-Chrysler and FIAT.

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.

This book embarks on a contemporary analysis of the interaction of economics and law relating to air transport, delving into the major issues that plague the industry. It shows how some of the thorny and frustrating issues could be approached sensibly. Among the issues discussed are the anomaly of exponential growth of air transport which makes airline profitability continue to be poor; the legislative impediments in most countries that preclude direct foreign investment in the industry; the confounding and muddled mess behind the economics of aircraft engine emissions; and the inexplicable reality that, although civil aviation is primarily meant to meet the needs of the people of the world, State regulators have upended the equation and given priority to national interests over the interests of the passenger. The book will be of interest to economists and lawyers alike who deal with air transport issues, and also to academics and students in the area of transportation as well as regulators and airlines.

Debido a su aceptable rendimiento en un amplio rango de potencias y tamaños, el motor de combustión interna alternativo (MCIA) es uno de los motores térmicos de mayor difusión en la industria. Si a esto se le añade su elevada potencia especifica y la disponibilidad de combustible, el resultado es que el MCIA es el motor dominante en la propulsion de vehiculos y permanece de forma casi monopolista en el sector de la automocion. Por lo tanto, el estudio de los MCIA resulta una materia fundamental en la formacion de los futuros ingenieros. En este sentido, el presente texto recopila los apuntes de clase de la asignatura de Motores Alternativos cursada por los alumnos de 3º de Ingenieria Aeronautica, por lo que su objetivo es guiar al estudiante a lo largo de la asignatura. El texto trata el tema de los MCIA con el rigor cientifico necesario, si bien este no pretende ser un libro de consulta. Para tal objeto, se ha publicado el libro "Motores de combustion interna alternativos", editado por los profesores F. Payri y J.M. Desantes que ha servido como base para la preparacion del texto docente que aqui se presenta.

El aeropuerto de Girona-Costa Brava es un claro exponente de cómo el turismo influye en el desarrollo del transporte y sus infraestructuras. Efectivamente, fueron aquellos primeros turistas que conocieron estas tierras catalanas, tras aterrizar en los aeropuertos vecinos de Barcelona y Perpignan, quienes propiciaron la creacion y posterior desarrollo de este aeropuerto, como entrada abierta a las turisticas localidades de la Costa Brava.Con habilidad y teson, las autoridades municipales y provinciales, asi como las entidades sociales y economicas de la region apoyaron su construccion. En 1967 este proyecto se hizo realidad, lo que supuso un gran apoyo e impulso para el desarrollo turistico y en general para toda la economia regional.Con la liberalizacion del transporte aereo, impulsada por la Union Europea, el Aeropuerto de Girona ha visto resurgir su potencial, superando las previsiones mas optimistas. No cabe duda que la contribucion de sus trabajadores y las inversiones llevadas a cabo por Aena han permitido hacer frente a este crecimiento y conservar unas importantes expectativas de desarrollo futuro. Por ello la publicacion de este libro resulta una oportunidad para dar a conocer toda una historia de superacion, esfuerzo y colaboracion entre instituciones y trabajadores que han permitido que hoy se dibuje un devenir prometedor y repleto de esperanzas para esta infraestructura gerundense.Indice de la publicacion:1.
