High-speed Railway Bridges: Conceptual Design Guide

by José Romo Alejandro Perez-Caldentey Manuel Cuadrado

The need for large-scale bridges is constantly growing worldwide, as the expansion of transport infrastructures with rail roads and high-speed lines is an important current task in many regions. This book develops all aspects referring to the structural conceptional design and analysis that are taken into account when planning a bridge or viaduct for a high-speed rail line. That includes the characteristics of the railway traffic such as speeds, actions, limit states, etc., and a detailed analysis of the superstructure of the track with its various components and singular elements. One of the special features of the book is that it not only highlights the bridge typologies and structural components related to the bridge design but also takes into account the issues of the track construction. The design basis, the requirements from different situations, and solutions are given. Special attention is paid to the interactions between the structure and the track and to the dynamic nature of railway actions, studying the dynamic response of the structure and its influence on the behaviour of the track and its components as well as on safety, traffic flow quality, and maintenance needs. The particulars of the design of high-speed rail bridges located in seismic areas are included as well. Numerous examples in all chapters serve the book's character as a useful guide to HSR bridge design, and to prevent typical problems and errors. An appendix with selected HSR bridges built worldwide completes the work. With this work the authors provide first-hand experience gained from many years of planning of completed bridges for high-speed rail lines.

High-Speed Railway Operation Under Emergent Conditions: Theoretical Methodology and Applications (Advances in High-speed Rail Technology)

by Limin Jia Li Wang Yong Qin

High Static, Dead Lines: Sonic Spectres & the Object Hereafter

by Kristen Gallerneaux

A literary mix tape that explores the entwined boundaries between sound, material culture, landscape and esoteric belief.Trees rigged up to the wireless radio heavens. A fax machine used to decode the language of hurricanes. A broadcast ghost that hijacked a television station to terrorize a city. A failed computer factory in the desert with a slap-back echo resounding into ruin.In High Static, Dead Lines, media historian and artist Kristen Gallerneaux weaves a literary mix tape that explores the entwined boundaries between sound, material culture, landscape, and esoteric belief. Essays and fictocritical interludes are arranged to evoke a network of ley lines for the &“sonic spectre&” to travel through—a hypothetical presence that manifests itself as an invisible layer of noise alongside the conventional histories of technological artifacts.The objects and stories within span from the mid-nineteenth century to the present day, touching upon military, communications, and cultural history. A connective thread is the recurring presence of sound—audible, self-generative, and remembered—charting the contentious sonic histories of paranormal culture.

High Steaks

by Eleanor Boyle

Each year the average North American ingests well over two hundred pounds of animal protein. Meanwhile the global appetite for meat has increased dramatically. But feeding our meat addiction comes at tremendous cost. Maintaining our current level of consumption is ecologically impossible in the longterm and undermines our personal health and community well-being.High Steaks documents the disastrous consequences of modern large-scale industrial meat production and excessive consumption, including:*The loss of vast tracts of arable land and fresh water to intensive livestock production*Increased pollution, loss of biodiversity, deforestation, and accelerating climate change*The environmental and health impacts of too much animal fat, and of antibiotics and other chemicals in our food.Timely and compelling, this powerful book offers a modest, commonsense approach to a serious problem, suggesting strategies for all of us to cut back on our consumption of animal products and ensure that the meat we do consume is produced in a sustainable, ecologically responsible manner. At the same time, High Steaks describes progressive food policy shifts that will discourage factory farming and encourage people to eat in ways that support ecosystems and personal health.Eleanor Boyle has been teaching and writing for twenty-five years, with a focus on food systems and their social, environmental, and health consequences. As well as working with organizations aiming for better food policy, she holds an MSc in food policy and is an instructor at the Centre for Sustainability at the University of British Columbia.

by Fredrik Öisjöen

This thesis describes the challenging task of developing high critical temperature superconducting quantum interference devices (high-Tc SQUIDs) and using them as sensors for biomedical applications, including magnetic immunoassays, magnetoencephalography and magnetic resonance imaging (MRI). The first part of this work discusses the development of fast magnetic immunoassays, which can be used to improve the sensitivity, or to create new, unique point-of-care diagnostics systems. The second part shows that high-Tc SQUIDs might make magnetoencephalography more available, thus opening the field of high-Tc SQUID-based magnetoencephalography for recording brain functions. This technique can be combined with ultra-low field MRI which is discussed in the last part. This combination may provide a new unique tool for studies of brain functions. This work does not simply improve on existing technology but opens possibilities for novel advanced medical devices and techniques.

High-Temperature Mechanical Hysteresis in Ceramic-Matrix Composites

by Longbiao Li

This book focuses on mechanical hysteresis behavior in different fiber-reinforced ceramic-matrix composites (CMCs), including 1D minicomposites, 1D unidirectional, 2D cross-ply, 2D plain-woven, 2.5D woven, and 3D needle-punched composites. Ceramic-matrix composites (CMCs) are considered to be the lightweight high-temperature materials for hot-section components in aeroengines with the most potential. To improve the reliability and safety of CMC components during operation, it is necessary to conduct damage and failure mechanism analysis, and to develop models to predict this damage as well as fracture over lifetime - mechanical hysteresis is a key damage behavior in fiber-reinforced CMCs. The appearance of hysteresis is due to a composite’s internal damage mechanisms and modes, such as, matrix cracking, interface debonding, and fiber failure. Micromechanical damage models and constitutive models are developed to predict mechanical hysteresis in different CMCs. Effects of a composite’s constituent properties, stress level, and the damage states of the mechanical hysteresis behavior of CMCs are also discussed. This book also covers damage mechanisms, damage models and micromechanical constitutive models for the mechanical hysteresis of CMCs. This book will be a great resource for students, scholars, material scientists and engineering designers who would like to understand and master the mechanical hysteresis behavior of fiber-reinforced CMCs.
