'The traditional analysis of infrastructure networks has provided the conceptual rationalization for centralized monopolies for a century. In recent years, liberalization has shown that much wider participation can be beneficial. Innovative development in decentralized networks can be driven from below if government policies permit it, as vividly demonstrated by the Internet. This book contributes to a much needed exploration into the characteristics and implications of decentralized networks being driven from below, introducing new perspectives on the conception and analysis of infrastructure networks.' William H. Melody, Aalborg University, Denmark and Delft University of Technology, The Netherlands The notion of inverse infrastructures that is, bottom-up, user-driven, self-organizing networks gives us a fresh perspective on the omnipresent infrastructure systems that support our economy and structure our way of living. This fascinating book considers the emergence of inverse infrastructures as a new phenomenon that will have a vast impact on consumers, industry and policy. Using a wide range of theories, from institutional economics to complex adaptive systems, it explores the mechanisms and incentives for the rise of these alternatives to large-scale infrastructures and points to their potential disruptive effect on conventional markets and governance models. The approach in this unique book challenges the existing literature on infrastructures, which primarily focuses on large technical systems (LTSs). Rather, this study highlights unprecedented developments, analyzing the differences and complementarity between LTSs and inverse infrastructures. It illustrates that even large infrastructures need not require a blueprint design or top-down and centralized control to run efficiently. The expert contributors draw upon a captivating and wide-ranging set of case studies, including: Wikipedia; wind energy cooperatives, Wireless Leiden, rural telecom in developing countries, local radio and television distribution, the collection of waste paper, syngas infrastructure design, and e-government projects. The book discusses the feasibility of temporary infrastructures and unheard of ownership arrangements, and concludes that inverse networks represent a critical transformation of the accepted model of infrastructure development. Laying a foundation for future research in the area and suggesting ways to bridge the gap between policy and practice, this path-breaking book will prove a riveting read for academics, students and researchers across a number of disciplines including economics, business, management, innovation, and technology and policy studies.

Inverse problems need to be solved in order to properly interpret indirect measurements. Often, inverse problems are ill-posed and sensitive to data errors. Therefore one has to incorporate some sort of regularization to reconstruct significant information from the given data. A Taste of Inverse Problems: Basic Theory and Examples?presents the main achievements that have emerged in regularization theory over the past 50 years, focusing on linear ill-posed problems and the development of methods that can be applied to them. Some of this material has previously appeared only in journal articles. This book rigorously discusses state-of-the-art inverse problems theory, focusing on numerically relevant aspects and omitting subordinate generalizations; presents diverse real-world applications, important test cases, and possible pitfalls; and treats these applications with the same rigor and depth as the theory.

While the prediction of observations is a forward problem, the use of actual observations to infer the properties of a model is an inverse problem. Inverse problems are difficult because they may not have a unique solution. The description of uncertainties plays a central role in the theory, which is based on probability theory. This book proposes a general approach that is valid for linear as well as for nonlinear problems. The philosophy is essentially probabilistic and allows the reader to understand the basic difficulties appearing in the resolution of inverse problems. The book attempts to explain how a method of acquisition of information can be applied to actual real-world problems, and many of the arguments are heuristic.

This volume offers a gradual exposition to matrix theory as a subject of linear algebra. It presents both the theoretical results in generalized matrix inverses and the applications. The book is as self-contained as possible, assuming no prior knowledge of matrix theory and linear algebra. The book first addresses the basic definitions and concepts of an arbitrary generalized matrix inverse with special reference to the calculation of {i,j,...,k} inverse and the Moore–Penrose inverse. Then, the results of LDL* decomposition of the full rank polynomial matrix are introduced, along with numerical examples. Methods for calculating the Moore–Penrose’s inverse of rational matrix are presented, which are based on LDL* and QDR decompositions of the matrix. A method for calculating the A(2)T;S inverse using LDL* decomposition using methods is derived as well as the symbolic calculation of A(2)T;S inverses using QDR factorization. The text then offers several ways on how the introduced theoretical concepts can be applied in restoring blurred images and linear regression methods, along with the well-known application in linear systems. The book also explains how the computation of generalized inverses of matrices with constant values is performed. It covers several methods, such as methods based on full-rank factorization, Leverrier–Faddeev method, method of Zhukovski, and variations of the partitioning method.

Written by two practicing electrical engineers, this second edition of the bestselling Protection of Electricity Distribution Networks offers both practical and theoretical coverage of the technologies, from the classical electromechanical relays to the new numerical types, which protect equipment on networks and in electrical plants. A properly coordinated protection system is vital to ensure that an electricity distribution network can operate within preset requirements for safety for individual items of equipment, staff and public, and the network overall. Suitable and reliable equipment should be installed on all circuits and electrical equipment and to do this, protective relays are used to initiate the isolation of faulted sections of a network in order to maintain supplies elsewhere on the system. This then leads to an improved electricity service with better continuity and quality of supply.
