Book Description
The reliability and availability of lifelines during and after any natural hazard-caused disaster is a critical requirement to ensure that society can not only tolerate the effects of natural disaster but also recover to its pre-disaster state as fast as possible. The fixed communication infrastructure systems play a vital role not only during everyday life but also during and after natural disasters to provide communication with emergency services and to support the recovery of other lifelines due to inherent interdependencies. The major objectives of this research are: • Quantitative assessment of the impact of major earthquakes on fixed communication infrastructure and development of geospatial seismic hazard maps for the lifeline; • Quantitative seismic resilience evaluation of the fixed communication system; and • Guidelines and approaches to enhance the seismic resilience of the fixed communication infrastructure network. The study explores both the seismic induced physical damages to the fixed communication infrastructure systems and the degradation of the communication systems performance due to high surge in traffic demand which results in congestion during and after an earthquake. In this thesis, the approaches and methods are motivated by the seismic risk assessment (SRA) and Resilience-Compositional Demand Supply (Re-CoDeS) frameworks. This study validates these methods through a case study to assess the possible impact of four scenarios of Alpine Fault 8 (AF8) earthquake on the West Coast, New Zealand fixed communication infrastructure system. The AF8 seismic damages to central offices (COs) are modelled on GIS map to produce a seismic hazard map which aims to aid the investment strategies to enhance the resilience of the fixed communication infrastructure system. This study also uses the fragility functions of COs, which is a key input for the SRA. Based on the results and findings from the case study, it is found that as Modified Mercalli Intensity (MMI) level increases, the severity of damage to COs increases. A Southern Hypocenter AF8 scenario would result in extensive (ds2) or complete (ds3) damage to a greater number of COs than in any other AF8 earthquake scenarios. It is observed that there is a higher risk of losing Greymouth (T2 CO) in case of AF8 Central and Southern Hypocenter MMI 9 scenarios than the other two AF8 scenarios under study. Traffic tolerance (capacity) measured in Mbps is used as a metric for seismic resilience evaluation. It can also be concluded that the West Coast fixed communication infrastructure system would have high seismic resilience (Rsys) for MMI 8 level for AF8 Central and Southern Hypocenter compared to MMI level 9.

Book Description
Infrastructure systems are essential to the functioning of contemporary societies and economies. A major disruption to the built environment can lead to severe public safety issues and economic losses. Within the past few decades, modern control and information technologies have been rapidly developed in an attempt to improve the reliability of individual utility systems by exchanging technologies across them. One of the major ramifications is the emergence of interdependencies among these critical infrastructure systems, especially when facing major disruptions. Failure of an individual system becomes more likely to affect the functionality of other interconnected infrastructure systems. In order to mitigate such consequences, the mechanics of interdependencies and failure propagation among the systems must be understood. : This research focuses on the development of a framework for probabilistically quantifying interdependent responses of two essential infrastructure systems - telecommunication and electric power systems - subjected to seismic hazards, which are one of the most powerful and geographically extensive threats. The study explores the effects of seismic hazards beyond the obvious seismic-induced physical damage to utility system facilities. In particular, the seismic evaluation of telecommunication systems considers the degradation of system performance due to physical damage and the abnormally high usage demands in telecommunication systems expected after catastrophic earthquakes. Specifically, a newly developed seismic-induced congestion model is proposed, and the probabilistic formulations of the critical interdependencies across telecommunication and power systems are presented in a probabilistic framework. The study illustrates the procedure for fragility analysis of interdependent systems and presents a practical application through a test bed implementation in Shelby County, TN.

Book Description
The safe and reliable performance of many systems with which we interact daily has been achieved through the analysis and management of risk. From complex infrastructures to consumer durables, from engineering systems and technologies used in transportation, health, energy, chemical, oil, gas, aerospace, maritime, defence and other sectors, the management of risk during design, manufacture, operation and decommissioning is vital. Methods and models to support risk-informed decision-making are well established but are continually challenged by technology innovations, increasing interdependencies, and changes in societal expectations. Risk, Reliability and Safety contains papers describing innovations in theory and practice contributed to the scientific programme of the European Safety and Reliability conference (ESREL 2016), held at the University of Strathclyde in Glasgow, Scotland (25—29 September 2016). Authors include scientists, academics, practitioners, regulators and other key individuals with expertise and experience relevant to specific areas. Papers include domain specific applications as well as general modelling methods. Papers cover evaluation of contemporary solutions, exploration of future challenges, and exposition of concepts, methods and processes. Topics include human factors, occupational health and safety, dynamic and systems reliability modelling, maintenance optimisation, uncertainty analysis, resilience assessment, risk and crisis management.

Book Description
Engineering Aspects of Shape Memory Alloys provides an understanding of shape memory by defining terms, properties, and applications. It includes tutorials, overviews, and specific design examples—all written with the intention of minimizing the science and maximizing the engineering aspects. Although the individual chapters have been written by many different authors, each one of the best in their fields, the overall tone and intent of the book is not that of a proceedings, but that of a textbook. The book consists of five parts. Part I deals with the mechanism of shape memory and the alloys that exhibit the effect. It also defines many essential terms that will be used in later parts. Part II deals primarily with constrained recovery, but to some extent with free recovery. There is an introductory paper which defines terms and principles, then several specific examples of products based on constrained recovery. Both Parts III and IV deal with actuators. Part III introduces engineering principles while Part IV presents several of the specific examples. Finally, Part V deals with superelasticity, with an introductory paper and then several specific examples of product engineering.

Book Description
The United States will certainly be subject to damaging earthquakes in the future. Some of these earthquakes will occur in highly populated and vulnerable areas. Coping with moderate earthquakes is not a reliable indicator of preparedness for a major earthquake in a populated area. The recent, disastrous, magnitude-9 earthquake that struck northern Japan demonstrates the threat that earthquakes pose. Moreover, the cascading nature of impacts-the earthquake causing a tsunami, cutting electrical power supplies, and stopping the pumps needed to cool nuclear reactors-demonstrates the potential complexity of an earthquake disaster. Such compound disasters can strike any earthquake-prone populated area. National Earthquake Resilience presents a roadmap for increasing our national resilience to earthquakes. The National Earthquake Hazards Reduction Program (NEHRP) is the multi-agency program mandated by Congress to undertake activities to reduce the effects of future earthquakes in the United States. The National Institute of Standards and Technology (NIST)-the lead NEHRP agency-commissioned the National Research Council (NRC) to develop a roadmap for earthquake hazard and risk reduction in the United States that would be based on the goals and objectives for achieving national earthquake resilience described in the 2008 NEHRP Strategic Plan. National Earthquake Resilience does this by assessing the activities and costs that would be required for the nation to achieve earthquake resilience in 20 years. National Earthquake Resilience interprets resilience broadly to incorporate engineering/science (physical), social/economic (behavioral), and institutional (governing) dimensions. Resilience encompasses both pre-disaster preparedness activities and post-disaster response. In combination, these will enhance the robustness of communities in all earthquake-vulnerable regions of our nation so that they can function adequately following damaging earthquakes. While National Earthquake Resilience is written primarily for the NEHRP, it also speaks to a broader audience of policy makers, earth scientists, and emergency managers.

Book Description
Risk communication is crucial to building community resilience and reducing risk from extreme events. True community resilience involves accurate and timely dissemination of risk information to stakeholders. This book examines the policy and science of risk communication in the digital era. Themes include public awareness of risk and public participation in risk communication and resilience building. The first half of the book focuses on conceptual frameworks, components, and the role of citizens in risk communication. The second half examines the role of risk communication in resilience building and provides an overview of some of its challenges in the era of social media. This book looks at the effectiveness of risk communication in socially and culturally diverse communities in the developed and developing world. The interdisciplinary approach bridges academic research and applied policy action. Contributions from Latin America and Asia provide insight into global risk communication at a time when digital technologies have rapidly transformed conventional communication approaches. This book will be of critical interest to policy makers, academicians, and researchers, and will be a valuable reference source for university courses that focus on emergency management, risk communication, and resilience.
