Transcontinental Infrastructure Needs to 2030/50 explores the long-term opportunities and challenges facing major gateway and transport hub infrastructures -- ports, airports and major rail corridors - in the coming decades. The report uses projections and scenarios to assess the broader economic outlook and future infrastructure requirements, and examines the options for financing these, not least against the backdrop of the economic recession and financial crisis which have significantly modified the risks and potential rewards associated with major infrastructure projects. Building on numerous in-depth case studies from Europe, North America and Asia, the report offers insights into the economic prospects for these key facilities and identifies policy options for improved gateway and corridor infrastructure in the future..

Whilst most contemporary books in the aerospace propulsion field are dedicated primarily to gas turbine engines, there is often little or no coverage of other propulsion systems and devices such as propeller and helicopter rotors or detailed attention to rocket engines. By taking a wider viewpoint, "Powered Flight - The Engineering of Aerospace Propulsion" aims to provide a broader context, allowing observations and comparisons to be made across systems that are overlooked by focusing on a single aspect alone. The physics and history of aerospace propulsion are built on step-by-step, coupled with the development of an appreciation for the mathematics involved in the science and engineering of propulsion. Combining the author''s experience as a researcher, an industry professional and a lecturer in graduate and undergraduate aerospace engineering, "Powered Flight - The Engineering of Aerospace Propulsion" covers its subject matter both theoretically and with an awareness of the practicalities of the industry. To ensure that the content is clear, representative but also interesting the text is complimented by a range of relevant graphs and photographs including representative engineering, in addition to several propeller performance charts. These items provide excellent reference and support materials for graduate and undergraduate projects and exercises. Students in the field of aerospace engineering will find that "Powered Flight - The Engineering of Aerospace Propulsion" supports their studies from the introductory stage and throughout more intensive follow-on studies.

Airbreathing Propulsion covers the physics of combustion, fluid and thermo-dynamics, and structural mechanics of airbreathing engines, including piston, turboprop, turbojet, turbofan, and ramjet engines. End-of-chapter exercises allow the reader to practice the fundamental concepts behind airbreathing propulsion, and the included PAGIC computer code will help the reader to examine the relationships between the performance parameters of different engines. Large amounts of data have on many different piston, turbojet, and turboprop engines have been compiled for this book and are included as an appendix. This textbook is ideal for senior undergraduate and graduate students studying aeronautical engineering, aerospace engineering, and mechanical engineering.

The author's approach is one of continuum models of the aerodynamic flow interacting with a flexible structure whose behavior is governed by partial differential equations. Both linear and nonlinear models are considered although much of the book is concerned with the former while keeping the latter clearly in view. A complete chapter is also devoted to nonlinear theory. The author has provided new insights into the classical inviscid aerodynamics and raises novel and interesting questions on fundamental issues that have too often been neglected or forgotten in the development of the early history of the subject. The author contrasts his approach with discrete models for the unsteady aerodynamic flow and the finite element model for the structure. Much of the aeroelasticity has been developed with applications formerly in mind because of its enormous consequences for the safety of aircraft. Aeroelastic instabilities such as divergence and flutter and aeroelastic responses to gusts can pose a significant hazard to the aircraft and impact its performance. Yet, it is now recognized that there are many other physical phenomena that have similar characteristics ranging from flows around flexible tall buildings and long span bridges, alternate energy sources such as electric power generation by smart structures to flows internal to the human body. From the foreword: "For the theorist and applied mathematician who wishes an introduction to this fascinating subject as well as for the experienced aeroelastician who is open to new challenges and a fresh viewpoint, this book and its author have much to offer the reader."

La energía geotérmica, a diferencia del resto de las energías renovables cuyo origen es la radiación solar, es la energía calorífica que transmite la tierra desde sus capas internas hacia la corteza terrestre. La energía geotérmica proviene del calor interior de la Tierra, cuyas manifestaciones se conocen por los volcanes, aguas termales, fumarolas y géiseres. El calor desprendido desde el interior de la tierra puede ser aprovechado por el hombre en función de la temperatura del fluido geotermal que determina sus posibles usos y aplicaciones. Por tanto, el objetivo de la geotermia es el aprovechamiento de esa energía calorífica del interior de la tierra.

This book stems from a research project funded by the Spanish Ministry of Science and Innovation that aimed to study energy networks in Europe (gas and electricity). The project was motivated by Directives 2009/72 and 73 of the European Parliament and of the Council, of 13 July 2009, concerning common rules for the internal market in electricity and natural gas (the so-called third energy package).The effective creation of an internal energy market (which should be completed in 2014) is inseparable from the process of constructing and using electricity and gas networks at European scale. And this effort calls for the complicity of the Member States. Hence the close relationship between European Union law and the relevant National laws, the narrative thread of this book, which aims to address the following topics: introduction or historical context; the division of competences; regulatory agencies; the construction of the networks: planning of the networks and coordination with territorial planning; the unbundling of activities; the right of access to the networks; cross-border transmission.The endresult is a frieze that highlights the characteristic features and evolution of the National laws, held up against the demands of European Union law. We hope that this explanation might contribute to a simpler and quicker implementation of the internal market and, particularly, the construction and use of the major gas and electricity networks in the European Union.The authors are professors of Administrative law at Universities in Spain, Italy, France and Germany, all recognised specialists regarding these subjects.

Game Theoretic Risk Analysis of Security Threats introduces reliability and risk analysis in the face of threats by intelligent agents. More specifically, game-theoretic models are developed for identifying optimal and/or equilibrium defense and attack strategies in systems of varying degrees of complexity. The book covers applications to networks, including problems in both telecommunications and transportation. However, the book''s primary focus is to integrate game theory and reliability methodologies into a set of techniques to predict, detect, diminish, and stop intentional attacks at targets that vary in complexity. In this book, Bier and Azaiez highlight work by researchers who combine reliability and risk analysis with game theory methods to create a set of functional tools that can be used to offset intentional, intelligent threats (including threats of terrorism and war). These tools will help to address problems of global security and facilitate more cost-effective defensive investments.

There is a large gap between the engineering course in tensor algebra on the one hand and the treatment of linear transformations within classical linear algebra on the other hand. The aim of this modern textbook is to bridge this gap by means of the consequent and fundamental exposition. The book primarily addresses engineering students with some initial knowledge of matrix algebra. Thereby the mathematical formalism is applied as far as it is absolutely necessary. Numerous exercises are provided in the book and are accompanied by solutions, enabling self-study. The last chapters of the book deal with modern developments in the theory of isotropic and anisotropic tensor functions and their applications to continuum mechanics and are therefore of high interest for PhD-students and scientists working in this area. This third edition is completed by a number of additional figures, examples and exercises. The text and formulae have been revised and improved where necessary.

A comprehensive approach to the air vehicle design process using the principles of systems engineering Due to the high cost and the risks associated with development, complex aircraft systems have become a prime candidate for the adoption of systems engineering methodologies. This book presents the entire process of aircraft design based on a systems engineering approach from conceptual design phase, through to preliminary design phase and to detail design phase. Presenting in one volume the methodologies behind aircraft design, this book covers the components and the issues affected by design procedures. The basic topics that are essential to the process, such as aerodynamics, flight stability and control, aero-structure, and aircraft performance are reviewed in various chapters where required. Based on these fundamentals and design requirements, the author explains the design process in a holistic manner to emphasise the integration of the individual components into the overall design. Throughout the book the various design options are considered and weighed against each other, to give readers a practical understanding of the process overall. Readers with knowledge of the fundamental concepts of aerodynamics, propulsion, aero-structure, and flight dynamics will find this book ideal to progress towards the next stage in their understanding of the topic. Furthermore, the broad variety of design techniques covered ensures that readers have the freedom and flexibility to satisfy the design requirements when approaching real-world projects.

Los objetivos de este texto son proporcionar criterios para la selección de materiales en el diseño de máquinas y, a la vez, ofrecer una panorámica de los principales materiales empleados en esta disciplina. En el se facilita una estructura comun de tablas de propiedades y se resaltan los aspectos mas caracteristicos de la aplicacion de cada uno de ellos. El contenido se estructura en cuatro capitulos. El primero trata de los criterios de seleccion; el segundo estudia los materiales ferricos, aceros y fundiciones; el tercero trata de los materiales metalicos no ferricos, y el ultimo, de los materiales no metalicos (plasticos, elastomeros, materiales compuestos y ceramicas. Es la traduccion de la segunda edicion de la obra original en catalan, revisada y ampliada. Como novedad basica respecto a la primera edicion, toma como referencia las normas EN (especialmente en los metales) y/o las ISO, y en un anexo se proporcionan tablas de equivalencias con las ultimas normas vigentes de los principales paises europeos (AENOR, AFNOR, BS, DIN y UNI) y con las normas americanas (ASTM, AISI, etc.) y japonesas (JIS). Tambien se han realizado varias ampliaciones, entre las que cabe destacar la incorporacion de los recubrimientos y los productos planos de acero recubiertos.

Las innovaciones técnicas en el ámbito de los materiales traslúcidos, ya sea vidrio, plástico o productos metálicos, han sido numerosas en los últimos años y han ampliado el abanico de soluciones que permiten el control luminico y visual. Las posibilidades de relacion entre el espacio interior y el exterior son ahora mucho mas variadas y ricas, y ofrecen a los arquitectos un catalogo de soluciones mas amplio para los objetivos de proyecto que persigan. La atmosfera de luz matizada, que antes solo era posible conseguir mediante vidrio tintado en masa, como en las vidrieras de las iglesias, piedra natural de exiguo espesor o papel, se reinterpreta en la actualidad mediante nuevos tipos de vidrio, diversos materiales plasticos (en placas o membranas) o productos metalicos (ya sean chapas perforadas o mallas tejidas). Este libro ofrece una vision actualizada y global sobre todo tipo de materiales traslucidos: vidrio, plastico y materiales metalicos. Asimismo, ofrece detalles constructivos y ejemplos concretos de su aplicacion en edificios ya construidos, e informacion tecnica detallada de sus propiedades de aislamiento termico o acustico, resistencia al fuego y grado de transmision luminica.

Los países europeos en su afán de cumplir con sus obligaciones dentro del Protocolo de Kyoto, están empeñados en cambiar sus sistemas energéticos a base de combustibles fósiles, por Biocombustibles; pero su produccion no les da abasto y han visto en los biocombustibles una posibilidad de seguir manteniendo su estilo de vida, sin incrementar sus emisiones de gases invernaderos. Sin embargo en Europa no existen tierras suficientes para la produccion de la cantidad de biocombustibles que se necesita, por lo que se han planteado la importacion de los mismos. Esto implica que tierras de vocacion agricola y que, al momento, son usadas para la produccion de alimentos, o ecosistemas naturales, van a ser utilizadas para la produccion de cultivos para la produccion de Biocombustibles. De acuerdo a un informe de la organizacion Worldwatch, para llenar el tanque de un automovil se necesita una cantidad de granos suficientes para alimentar a una persona.

Este libro tiene como objetivo fundamental enseñar a realizar mediciones y presupuestos tanto a los alumnos de arquitectura, arquitectura tecnica e ingeniería como a los profesionales con poca experiencia. Pero para alcanzar ese objetivo es imprescindible describir los restantes documentos escritos, variantes y complementos requeridos actualmente por un proyecto, es decir, todo aquello que se entrega habitualmente en formato DIN-A4, como la memoria y el pliego de condiciones.Este libro considera que una parte importante del trabajo del profesional de la edificacion se realiza antes, durante y despues del proyecto; considera que el proyecto no es solo una serie de planos con una memoria que los justifica, sino que todos sus documentos deben mantener un punto de vista integrado; demuestra que el presupuesto es una parte interesante, y no burocratica, del proyecto, que aporta valor al profesional y mejora la calidad de la construccion.Este libro se centra en el aprendizaje de los procesos y no en los contenidos concretos, es decir, no enseña a medir redondos o tabiques, pero dice como se aprende; se ciñe a la normativa vigente, identifica el origen de sus criterios y se pregunta sobre el objetivo de cada tarea, en lugar de dogmatizar sobre la forma de hacerla; es
