This edited volume compares seven countries in North America and Europe on the highly topical issue of oil and gas development that uses hydraulic fracturing or "fracking." The comparative analysis is based on the Advocacy Coalition Framework (ACF) and guided by two questions: First, in each country, what are current coalitions and the related policy output? Second, based on the current situation, what are the chances for future policy change? This book is the first to use a social science approach to analyze hydraulic fracturing debates and the first application of the ACF that is deliberately comparative. The contributions in this book advance our understanding about the formation of coalitions and development of public policy in the context of different forms of government and economically recoverable natural resources.

This book presents comprehensive experimental, numerical, and theoretical research on projectile impact analysis, such as the rigid projectile penetration/perforation of concrete and metallic targets, and shaped-charge-formed projectile and jet penetrations. Concrete and metal materials are widely used in protective structures in both civil engineering and armored vehicles, such as military fortifications, underground shelters, infantry fighting vehicles, and tanks, which are designed to withstand intentional or accidental impact loadings caused by projectiles and fragments, and the responses of these targets under projectile impact have been a topic of discussion for several decades. Written for researchers and engineers working in the fields of protective structures and high-speed penetration mechanics, the book is also a valuable reference for senior undergraduate and postgraduate students majoring in defense engineering, terminal ballistics and other related fields.

This thesis studies the effects of superplasticizers, polyacrylate latexes and asphalt emulsions, which differ in molecular/particle size from nanometers to microns, on the rheological properties of fresh cement pastes (FCPs), as well as the action mechanisms involved. It systematically investigates the rheological properties and microstructure of cement-based materials, and elucidates the adsorption behaviors of polycarboxylate polymers with different functional groups and their effects on cement hydration. Moreover, it reveals how the working mechanism of naphthalene sulfonate formaldehyde (NSF) differs from that of polycarboxylate ether-based (PCE) superplasticizers. Lastly, it develops a conceptual microstructure model and two rheological equations. These findings lend theoretical support to the development of new chemical admixtures and new, higher-performance, cement-based composites.

This book presents cutting-edge work on the most challenging research issues concerning intelligent transportation systems (ITS), introducing selected, highly relevant advanced research on scheduling and real-time communication for vehicular networks, as well as fault tolerance, test beds and simulations for ITS. The authors define new architectures that support cooperative sensing in ITS and offer guidance for the development of a reference end-to-end implementation. The presented results allow advanced traffic and travel management strategies to be formulated on the basis of reliable and real-time input data. The effectiveness of these new strategies, together with the proposed systems, is assessed in field trials and via simulations. The chapters in this book detail new research findings, algorithms, protocols, and the development of an implementation platform for ITS that merges and integrates heterogeneous data sources into a common system. In addition, they provide a set of advanced tools for the control, monitoring, simulation, and prediction of traffic that result in safer, more sustainable, and less congested roads. Work undertaken within the framework of the FP7 project ICSI (Intelligent Cooperative Sensing for Improved traffic efficiency) is also included in the research activities addressed.

This book shows how transit assignment models can be used to describe and predict the patterns of network patronage in public transport systems. It provides a fundamental technical tool that can be employed in the process of designing, implementing and evaluating measures and/or policies to improve the current state of transport systems within given financial, technical and social constraints. The book offers a unique methodological contribution to the field of transit assignment because, moving beyond "traditional" models, it describes more evolved variants that can reproduce:* intermodal networks with high- and low-frequency services;* realistic behavioural hypotheses underpinning route choice;* time dependency in frequency-based models; and* assumptions about the knowledge that users have of network conditionsthat are consistent with the present and future level of information that intelligent transport systems (ITS) can provide. The book also considers the practical perspective of practitioners and public transport operators who need to model and manage transit systems; for example, the role of ITS is explained with regard to their potential in data collection for modelling purposes and validation techniques, as well as with regard to the additional data on network patronage and passengers' preferences that influences the network-management and control strategies implemented. In addition, it explains how the different aspects of network operations can be incorporated in traditional models and identifies the advantages and disadvantages of doing so. Lastly, the book provides practical information on state-of-the-art implementations of the different models and the commercial packages that are currently available for transit modelling. Showcasing original work done under the aegis of the COST Action TU1004 (TransITS), the book provides a broad readership, ranging from Master and PhD students to researchers and from policy makers to practitioners, with a comprehensive tool for understanding transit assignment models.

First published in 1968, Jacob Feld's Construction Failure has long been considered the classic text on the subject. Retaining all of the key components of Feld's comprehensive exploration of the root causes of failure, this Second Edition addresses a multitude of important industry developments to bring this landmark work up to date for a new generation of engineers, architects, and students.

In addition to detailed coverage of current design tools, techniques, materials, and construction methods, Construction Failure, Second Edition features an entire chapter on the burgeoning area of construction litigation, including a thorough examination of alternative dispute resolution techniques. Like the original, this edition discusses technical and procedural failures of many different types of structures, but is now supplemented with new case studies to illustrate the dynamics of failure in action today.

Jacob Feld knew thirty years ago that in order to learn from our mistakes, we must first acknowledge and understand them. With this revised volume, Kenneth Carper has ensured that Feld's now-posthumous message will continue to be heard for years to come.

Jacob Feld's comprehensive work on failure analysis has now been skillfully amended to address current design and construction tools, materials, and practices. Building on the first edition's peerless examination of the causes and lessons of failure, Construction Failure, Second Edition provides you with expanded coverage of:

• Technical, procedural, structural, and nonstructural failures
• Natural hazards, earthworks, soil and foundation problems, and more
• Reinforced, precast and prestressed concrete, steel, timber, masonry, and other materials
• Responsibility and litigation concerns, dispute avoidance, and alternative dispute resolution techniques
• Construction safety issues
• Many different types of structures, including dams and bridges

Construction Failure has as much to teach us today as it did thirty years ago. This revised volume is an essential resource for design engineers, architects, construction managers, lawyers, and students in all of these fields.
