The role of an airport within the air transport system used to be largely incontestable. The system is now being shaped less by the concept of social service and more by market forces. Progressive liberalisation of air transport, together with trends to privatisation and globalisation are causing the roles of airports to change, for planning to become increasingly decentralised, and for the traffic to become more volatile. Airports are increasingly in competition for markets. Yet the markets are limited, and airport expansion is made difficult by environmental pressures that push towards sustainable transport, and the need to justify investment. The book will examine these pressures in order to identify changes that are required to the airport planning process. The major issues to be discussed are: forecasting in an uncertain world; airport market share; airline network choices; political settings and their consequences; economic justification and viability; environmental impacts and their mitigation; cooperative planning; and physical planning challenges. The issues will be illuminated by case studies of representative airport systems: intercontinental gateways, metropolitan multi airport system, provincial and regional airports and developing country systems. The final section will bring together suggestions for ways in which the industry can move forward to a green and profitable future with an appropriate provision of new capacity.

The Structural Design of Air Gas Ducts for Power Stations Industrial Boilers Applications
Size: 14.67 MB | Format:PDF | pages: 55
This document, "The Structural Design of Air and Gas Ducts for Power Stations and Industrial Boiler Applications", has been created to assist structural engineers when performing the structural analysis and design of ductwork. Air and gas ducts for fossil fuel power stations and industrial boiler applications are unique structures. Considering that ductwork structural analysis and design is not currently referenced or governed by any national code or design standards, this publication presents the structural engineer with current approaches for the structural analysis and design of air and flue-gas ductwork. Included are sections on: Material selection, behavior and performance; design loads, loading combinations and allowable stresses; thermal considerations; vibration considerations; structural arrangement and behavior; toggle duct behavior and expansion joint considerations; overall duct structural analysis and design methods; and design considerations for local elements of the structure, such as stiffeners, internal braces, connections, turning vanes, and other flow distribution devices. This document also discusses drawing and specification content, fabrication and construction techniques and considerations, duct support methods, and special considerations regarding the design of duct support structures. Finally, it talks about field maintenance examinations and inspections for the purpose of preventative maintenance or condition assessment.

Composite Materials presents recent developments and state-of-the-art achievements in the science and technology of composites. It identifies and discusses key and emerging issues for future progress in the multidisciplinary field of composites.
By bringing together leading experts and promising innovators from research institutions and academia, Composite Materials highlights unresolved issues and identifies opportunities for long-term research needs to provide the reader with a vision for the future in various fields of application of composite materials. A few of the many future directions highlighted in the book are increasingly multifunctional properties; complex, hybrid and nanoreinforced materials; and tailoring in multiple dimensions and directions. The wider areas covered include, but are not limited to, the following:
- biomedical engineering,
- civil engineering,
- aerospace engineering,
- automotive engineering, and
- naval engineering.
Composite Materials is designed to increase the reader’s understanding of the state of the art of composite materials in a variety of industrial sectors and to explore future needs and opportunities. It will therefore be of use to professionals working in the composites industry, research centers, and academia, who already have a graduate-level knowledge of composite materials.

as you know, we upgrade our best user to VIP members, VIP users is most active user in CivilEA, they work hard here, share knowledge with others, help other user, ....
VIP degree can`t be buy by users.
we have some privileges to VIP:
More PM storage, Less Limitations.
Access to VIP section (in this section we publish exclusive material & knowledge that have never find other places).
Can direct their links, they can use Download manager to download all links with resume support, DIRECT!
They are candidate to be a moderator of CivilEA.
Access to Online library of famous universities/
?
If you want, try to be a VIP.
Please do not PM CivilEA staff about how you can be VIP, all rules are simple, "Moderators are monitoring all users activity and if the found you as active members, will propose you for being VIP members then we will decide about it.
I not that by being VIP you will accept these rules:
#1: New VIPs will be propose by moderators. all users that have good activity at least during 3 month will be candidate for being VIP. Activities included: Post useful Posts, active in solving problems and request section.
#2: all accepted VIP members, will be remained in VIP group for 6 month, after this time they will be moved to registered group automatically. so they do not need to by subscription plan again unless they stop normal activities that lead to moving to "awaiting activation" group.
#3: if VIPs continue their activities, VIP time will be extend for next 6 month.
#4: CivilEA is free to changed VIP members group to any group without any notice, VIP is not permanent group for all.

This short book analyses the dynamic stability with respect to small perturbations, as well as the local damage of geometrically nonlinear elastic, spatially curved, open section beams with axial precompression. Transient waves, which are the surfaces of strong discontinuity and wherein the stress and strain fields experience discontinuities, are used as small perturbations; in so doing the discontinuities are considered to be of small magnitude. Such waves are initiated during low-velocity impacts upon thin-walled beams. The theory of discontinuities and the method of ray expansions which allow one to find the desired fields behind the fronts of the transient waves in terms of discontinuities in time-derivatives of the values to be found, are used as the methods of solution for short-time dynamic processes. The example of using the ray expansions for analyzing the impact response of spatially curved thin-walled beams of open profile is demonstrated by solving the problem about the normal impact of an elastic hemispherical-nosed rod upon an elastic arch representing itself a channel-beam curved along an arc of the circumference. The influence of the initial stresses on the dynamic fields has been investigated.

This is the completely updated revision of the highly regarded book Exploration Seismology. Available now in one volume, this textbook provides a complete and systematic discussion of exploration seismology. The first part of the book looks at the history of exploration seismology and the theory - developed from the first principles of physics. All aspects of seismic acquisition are then described. The second part of the book goes on to discuss data-processing and interpretation. Applications of seismic exploration to groundwater, environmental and reservoir geophysics are also included. The book is designed to give a comprehensive up-to-date picture of the applications of seismology. Exploration Seismology's comprehensiveness makes it suitable as a text for undergraduate courses for geologists, geophysicists and engineers, as well as a guide and reference work for practising professionals.
