Ice and Construction

Author: L.Makkonen - editor | Size: 2.1 MB | Format: PDF | Publisher: Spon Press | Year: 1994 | pages: 112 | ISBN: 0419200207

[Image: 78770608953871521519.jpg]


[Image: info.png]

This book focuses on two areas of ice technology: the use of ice as a construction material and the problems caused by ice to constructions. In connection with describing past and potential future applications of using ice in construction, a detailed discussion on the mechanical properties of ice is given. A state of the art description on ice-making methods, melt protection, methods and reinforcement of ice with the materials are covered.

  Track-Bridge Interaction on High-Speed Railways
Posted by: ir_71 - 12-09-2011, 04:36 PM - Forum: Bridge (Project and Technology) - Replies (4)

Track-Bridge Interaction on High-Speed Railways

Size: 8.7 MB | Format: PDF | Publisher: Taylor & Francis | Year: 2008 | pages: 222 | ISBN: 0415457742

[Image: 54108630915377369012.jpeg]


[Image: info.png]

The construction of high-speed railways includes a wide variety of aspects, ranging from safety to new types of equipment and construction solutions. All these require state-of-art technologies, and in recent years design concepts for high-speed railways have improved. The focus in this volume is on the interaction between rail track and bridges. Track-bridge interaction sets a limit to the vibration and deformability of structures, so that accelerations, stresses and track deformations are controlled, circulation safety is satisfied, and design solutions for bridges are determined.

  Greening Airports: Advanced Technology and Operations
Posted by: portal61 - 12-09-2011, 03:32 PM - Forum: Traffic Engineering - Replies (1)


Greening Airports: Advanced Technology and Operations (Green Energy and Technology)

Author: Milan Jani | Size: 1.44 MB | Format: PDF | Publisher: Springer | Year: 2011 | pages: 220 | ISBN: 9780857296573

[Image: 07815086926209603965.jpg]


[Image: info.png]

Greening Airports considers the “greening”, i.e., more sustainable development, of the entire air transport system – airports, air traffic control, and airlines – that could be achieved by the development and implementation of advanced operations and technologies.

A broad overview of the general concept is given at the start of Greening Airports, which then goes on to provide a system for monitoring and assessing the level of greening of both the air transport system and individual airports. These are followed by analysis and modelling of the potential effects of particular advanced operations and technologies on the greening of airports and their local airspace. These include:

the development of a large airport into a multimodal transport node by connecting it to a high speed rail network;
the use of operations supported by new and existing air traffic control technologies to increase landing capacity of existing runways;
the use of liquid hydrogen as a commercial aviation fuel; and
the improvement of airport ground accessibility by a light rail rapid transit system.

Greening Airports is written for researchers, planners, operators and policy makers in air transport.

  Noise-Induced Phenomena in the Environmental Sciences
Posted by: portal61 - 12-09-2011, 03:07 PM - Forum: Environmental Engineering - Replies (1)


Noise-Induced Phenomena in the Environmental Sciences

Author: Francesco Laio, Luca Ridolfi, Paolo D'Odorico | Size: 17.24 MB | Format: PDF | Publisher: Cambridge University Press | Year: 2011 | pages: 328

[Image: 52368086841496535725.jpg]

Randomness is ubiquitous in nature. Random drivers are generally considered a source of disorder in environmental systems. However, the interaction between noise and nonlinear dynamics may lead to the emergence of a number of ordered behaviors (in time and space) that would not exist in the absence of noise. This counterintuitive effect of randomness may play a crucial role in environmental processes. For example, seemingly "random" background events in the atmosphere can grow into larger instabilities that have great effects on weather patterns. This book presents the basics of the theory of stochastic calculus and its application to the study of noise-induced phenomena in environmental systems. It will be great reference text for ecologists, geoscientists, and environmental engineers interested in the study of stochastic environmental dynamics.

  CRC Standard Probability and Statistics Tables and Formulae

CRC Standard Probability and Statistics Tables and Formulae

Author: Daniel Zwillinger, Stephen Kokoska | Size: 3.65 MB | Format: PDF | Publisher: CRC Press |
Year: December 27, 1999 | pages: 568 | ISBN: 1584880597, ISBN-13: 978-1584880592

[Image: 18244058806651252021.jpg]

Whether you are a statistician, engineer, or businessperson, you need statistics. You want to be able to easily reference tables, find formulas, and know how to use them so you can extract information from data without getting bogged down by advanced statistical methods. Your goal is to determine the appropriate statistical procedures and interpret the results. Standard Probability and Statistics: Tables and Formulae provides the tools you need to do just that. Logically organized and reaching far beyond a mere catalog, a textual description accompanies each entry- most include an example. The topics addressed are directly applicable to modern business and engineering as well as to statistics, including regression analysis, ANOVA, decision theory, signal processing, and control theory. The result is an accessible, example-oriented handbook that supplies the basic principles, the most commonly used values, and the information to make them work for you. It is easy to fill a statistics reference with hundreds of pages of tables - sometimes for just one test. This handbook is much more. With topics ranging from classical statistics to modern applications, Standard Probability and Statistics fills the need for an up-to-date, authoritative statistics reference.

  Erosion and Sedimentation, Second Edition
Posted by: portal61 - 12-09-2011, 01:25 PM - Forum: Water & Hydraulic Engineering - Replies (3)


Erosion and Sedimentation, 2nd Edition

Author: Pierre Y. Julien | Size: 3.3 MB | Format: PDF | Publisher: Cambridge University Press | Year: 2010 | pages: 392 | ISBN: 0521830389

[Image: 51143559349991239237.jpg]


[Image: info.png]

The second edition of this acclaimed, accessible textbook brings the subject of sedimentation and erosion completely up-to-date, providing an excellent primer on both fundamental concepts of sediment-transport theory and methods for practical applications. The structure of the first edition is essentially unchanged, but all the chapters have been updated, with several chapters reworked and expanded significantly. Examples of the new additions include the concept of added mass, the Modified Einstein Procedure, sediment transport by size fractions, sediment transport of sediment mixtures, and new solutions to the Einstein Integrals. Many new examples and exercises have been added. Erosion and Sedimentation is an essential textbook on the topic for students in civil and environmental engineering and the geosciences, and also as a handbook for researchers and professionals in engineering, the geosciences and the water sciences.

  Hybrid Simulation: Theory, Implementation and Applications
Posted by: portal61 - 12-09-2011, 12:54 PM - Forum: General Books - Replies (4)


Hybrid Simulation: Theory, Implementation and Applications

Author: Victor Saouma, M.V. Sivaselvan | Size: 8.05 MB | Format: PDF | Publisher: Taylor & Francis | Year: 2008 | pages: 242

[Image: 07193180211216069106.jpg]


[Image: info.png]

Hybrid Simulation deals with a rapidly evolving technology combining computer simulation (typically finite element) and physical laboratory testing of two complementary substructures. It is a cost effective alternative to shaking table test, and allows for the improved understanding of complex coupled systems. Traditionally, numerical simulation and physical tests have been uncoupled and performed separately. In this simulation paradigm the coupled nature of the simulation allows for improved understanding, and more efficient design since the factor of safety does not have to be arbitrarily inflated to account for uncertainties of uncoupling. It is a multidisciplinary technology which relies heavily on control theory, computer science, and numerical techniques.
