Soft Computing Based Modeling in Intelligent Systems

This book proposes three liability regimes to combat the wide responsibility gaps caused by AI systems - vicarious liability for autonomous software agents (actants); enterprise liability for inseparable human-AI interactions (hybrids); and collective fund liability for interconnected AI systems (crowds). Based on information technology studies, the book first develops a threefold typology that distinguishes individual, hybrid and collective machine behaviour. A subsequent social science analysis specifies the socio-digital institutions related to this threefold typology. Then it determines the social risks that emerge when algorithms operate within these institutions. Actants raise the risk of digital autonomy, hybrids the risk of double contingency in human-algorithm encounters, crowds the risk of opaque interconnections. The book demonstrates that the law needs to respond to these specific risks, by recognising personified algorithms as vicarious agents, human-machine associations a

Phylogenetic combinatorics is a branch of discrete applied mathematics concerned with the combinatorial description and analysis of phylogenetic trees and related mathematical structures such as phylogenetic networks and tight spans. Based on a natural conceptual framework, the book focuses on the interrelationship between the principal options for encoding phylogenetic trees: split systems, quartet systems and metrics. Such encodings provide useful options for analyzing and manipulating phylogenetic trees and networks, and are at the basis of much of phylogenetic data processing. This book highlights how each one provides a unique perspective for viewing and perceiving the combinatorial structure of a phylogenetic tree and is, simultaneously, a rich source for combinatorial analysis and theory building. Graduate students and researchers in mathematics and computer science will enjoy exploring this fascinating new area and learn how mathematics may be used to help solve topical problem

Approaching wireless Internet security from the position of system architecture, this text describes the cryptographic and protocol-based tools for Internet security with a focus on understanding the system architecture of existing Internet security, and on developing architectural changes for new security services. Introducing the topics of security threats in wireless networks, security services for countering those threats, and the process of defining functional architecture for network systems, the author also discusses examples of wireless Internet security systems such as wireless network access control, local IP subnet configuration and address resolution, and location privacy. Each chapter describes the basic network architecture and protocols for the system under consideration, the security threats faced, a functional architecture, and the important Internet protocols that implement the architecture. This is an ideal resource for graduate students of electrical engineering and

Philosophy of Experimental Biology explores some central philosophical issues concerning scientific research in experimental biology, including genetics, biochemistry, molecular biology, developmental biology, neurobiology, and microbiology. It seeks to make sense of the explanatory strategies, concepts, ways of reasoning, approaches to discovery and problem solving, tools, models and experimental systems deployed by scientific life science researchers and also integrates developments in historical scholarship, in particular the New Experimentalism. It concludes that historical explanations of scientific change that are based on local laboratory practice need to be supplemented with an account of the epistemic norms and standards that are operative in science. This book should be of interest to philosophers and historians of science as well as to scientists.

The central models of theoretical physics have been extraordinarily successful in describing and predicting the behaviour of physical systems under an enormous range of conditions. But why are these mathematical theories so successful, and how is their structure influenced by the nature of the observations on which they are inevitably based? This intriguing book examines these subtle and fundamental issues, and concludes with the assertion that successful prediction provides compelling support for belief in a world independent of the observer. Dealing with important and basic aspects of the general framework of physics, this book will appeal to undergraduate and graduate students in the physical sciences, and to anyone with an interest in the empirical and metaphysical foundations of science.

Since the days of Montesquieu and Jefferson, political decentralization has been seen as a force for better government and economic performance. It is thought to bring government 'closer to the people', nurture civic virtue, protect liberty, exploit local information, stimulate policy innovation, and alleviate ethnic tensions. Inspired by such arguments, and generously funded by the major development agencies, countries across the globe have been racing to devolve power to local governments. This book re-examines the arguments that underlie the modern faith in decentralization. Using logical analysis and formal modeling, and appealing to numerous examples, it shows that most are based on vague intuitions or partial views that do not withstand scrutiny. A review of empirical studies of decentralization finds these as inconclusive and mutually contradictory as the theories they set out to test.

First published in 1956, this volume constitutes an attempt to identify the moral basis of Burke's political thought. Given Burke's stated belief that contingent political systems are held together by an essential basis in moral principles, this can be seen as a problem of fundamental importance in gaining an understanding of his theories. The obvious difficulty of such an exposition consists in attempting to create common ground between abstract concepts and the mutability of the empirically observed world. The author meets this difficulty with an approach based upon the subtle analysis of particular aspects in Burke's moral thought as they interact with the world. This book will be of value to anyone with an interest in philosophy, political theory, and the development of the British political system.

How hacking cultures drive contemporary capitalism and the future of innovation.In Resistance to the Current, Johan Söderberg and Maxigas examine four historical case studies of hacker movements and their role in shaping the twenty-first-century’s network society. Based on decades of field work and analysis, this intervention into current debates situates an exploding variety of hacking practices within the contradictions of capitalism. Depoliticized accounts of computing cultures and collaborative production miss their core driver, write Söderberg and Maxigas: the articulation of critique and its recuperation into innovations. Drawing on accounts of building, developing, and running community wireless networks, 3D printers, hackerspaces, and chat protocols, the authors develop a theoretical framework of critique and recuperation to examine how hackers―who have long held a reputation for being underground rebels―transform their outputs from communal, underground experiments to commerci

Statutory interpretation involves the reconstruction of the meaning of a legal statement when it cannot be considered as accepted or granted. This phenomenon needs to be considered not only from the legal and linguistic perspective, but also from the argumentative one - which focuses on the strategies for defending a controversial or doubtful viewpoint. This book draws upon linguistics, legal theory, computing, and dialectics to present an argumentation-based approach to statutory interpretation. By translating and summarizing the existing legal interpretative canons into eleven patterns of natural arguments - called argumentation schemes - the authors offer a system of argumentation strategies for developing, defending, assessing, and attacking an interpretation. Illustrated through major cases from both common and civil law, this methodology is summarized in diagrams and maps for application to computer sciences. These visuals help make the structures, strategies, and vulnerabilities

Since its inception some fifty years ago, cognitive science has seen a number of sea changes. Perhaps the best known is the development of connectionist models of cognition as an alternative to classical, symbol-based approaches. A more recent - and increasingly influential - trend is that of dynamical-systems-based, ecologically oriented models of the mind. Researchers suggest that a full understanding of the mind will require systematic study of the dynamics of interaction between mind, body, and world. Some argue that this new orientation calls for a revolutionary new metaphysics of mind, according to which mental states and processes, and even persons, literally extend into the environment. This book is a guide to this movement in cognitive science. Each chapter tackles either a specific area of empirical research or specific sector of the conceptual foundation underlying this research.

This volume was originally published in 1976. The difference types of society in the world - capitalist, socialist, mixed, etc. - have many features in common, despite their dissimilarities. The object of this book is to make clear the economic logic of society in general, which applies to socialist as well as capitalist economies. Taking the Japanese economy as an example, part of the book tries to explain how an actual economy can deviate from the 'ideal' laws of motion, and shows that such aberrations themselves obey certain rules. In a broad sense, it belongs in the domain of the theory of comparative systems. The book is based on lectures which Professor Morishima gave to students at Osaka University in 1967–1968. It is translated from the Japanese by D. W. Anthony.

Language is just one particularly highly developed form of primate communication. Recent years have seen increased attention to other forms: studies of animals in the wild, efforts to teach sign language to apes. This volume reflects perspectives from a variety of disciplines on the nature and function of primate signalling systems. Monkeys and apes, like people, live in a world in which they are constantly receiving and transmitting information. How can we interpret the ways in which they process it without imposing our own language-based categorizations? The problem is partly scientific, partly conceptual: that is, partly concerned with what language is. The authors' findings and insights will be of interest to a broad group of primatologists, linguists, psychologists, anthropologists and philosophers.

This book, geared toward academic researchers and graduate students, brings together research on all facets of how time and causality relate across the sciences. Time is fundamental to how we perceive and reason about causes. It lets us immediately rule out the sound of a car crash as its cause. That a cause happens before its effect has been a core, and often unquestioned, part of how we describe causality. Research across disciplines shows that the relationship is much more complex than that. This book explores what that means for both the metaphysics and epistemology of causes - what they are and how we can find them. Across psychology, biology, and the social sciences, common themes emerge, suggesting that time plays a critical role in our understanding. The increasing availability of large time series datasets allows us to ask new questions about causality, necessitating new methods for modeling dynamic systems and incorporating mechanistic information into causal models.

Advances in the growth of novel-engineered structures such as sophisticated semiconductor superlattices and heterostructures, as well as new nonlinear optical materials, have opened exciting possibilities for infrared sources, detectors, modulators and novel devices. Brought to maturity, such discrete devices could likely see widespread use in applications as diverse as infrared imaging, chemical sensing, surveillance, short-link and high-bandwidth communications. This book published by MRS, brings together a group of internationally recognized experts in the field to discuss progress in materials, physics, processing and device design and performance. Developments in materials for cooled and uncooled infrared systems based on pyroelectric, micro-bolometric, photovoltaic and photoconductive detectors are emphasized. Progress in compact infrared sources is also highlighted. Topics include: antimonide-related materials - growth, characterization and analysis; antimonide-related devices;

This complete introduction to two-dimensional (2-D) information theory and coding provides the key techniques for modeling data and estimating their information content. Throughout, special emphasis is placed on applications to transmission, storage, compression, and error protection of graphic information. The book begins with a self-contained introduction to information theory, including concepts of entropy and channel capacity, which requires minimal mathematical background knowledge. It then introduces error-correcting codes, particularly Reed-Solomon codes, the basic methods for error-correction, and codes applicable to data organized in 2-D arrays. Common techniques for data compression, including compression of 2-D data based on application of the basic source coding, are also covered, together with an advanced chapter dedicated to 2-D constrained coding for storage applications. Numerous worked examples illustrate the theory, whilst end-of-chapter exercises test the reader's un

This book presents an approach to introductory graduate courses on atomic structure. The author's approach utilizes conceptually powerful semiclassical modeling methods, and demonstrates the degree to which the Maslov-indexed EBK quantization elucidates the quantum mechanical formulation of level energies and lifetimes. It merges this with an update and extension of semiempirical data systematizations developed by Bengt Edlén to describe complex atoms, and adapts them to include the specification of lifetimes. The text emphasizes the historical basis of the nomenclature and methodologies of spectroscopy. However, interaction mechanisms are presented deductively, based on quantum mechanical and field theoretical models, rather than tracing their indirect paths of discovery. Many worked examples provide applications to areas such as astrophysics, hyperfine structure, and coherent anisotropic excitation. The book presents a firm foundation for specialists in atomic physics, as well as a c

How the tropes of science fiction infuse and inform avant-garde poetics and many other kindred arts This insightful, playful monograph from Golston does exactly what it advertises: modeling poetics based on how poetry (and some parallel artistic endeavors) has filtered through a century-plus of science fiction. This is not a book about science fiction in and of itself, but it is a book about the resonances of science-fiction tropes and ideas in poetic language. The germ of Golston's project is a throwaway line in Robert Smithson's Entropy and the New Monuments about how cinema supplanted nature as inspiration for many of his fellow artists: "The movies give a ritual pattern to the lives of many artists, and this induces a kind of 'low budget' mysticism, which keeps them in a perpetual trance." Golston charts how the demotic appeal of sci-fi, much like that of the B-movie, cross-pollinated into poetry and other branches of the avant garde. Golston creates what he calls a "regular Rub

The theory of Lyapunov exponents originated over a century ago in the study of the stability of solutions of differential equations. Written by one of the subject's leading authorities, this book is both an account of the classical theory, from a modern view, and an introduction to the significant developments relating the subject to dynamical systems, ergodic theory, mathematical physics and probability. It is based on the author's own graduate course and is reasonably self-contained with an extensive set of exercises provided at the end of each chapter. This book makes a welcome addition to the literature, serving as a graduate text and a valuable reference for researchers in the field.

Random matrices arise from, and have important applications to, number theory, probability, combinatorics, representation theory, quantum mechanics, solid state physics, quantum field theory, quantum gravity, and many other areas of physics and mathematics. This 2001 volume of surveys and research results, based largely on lectures given at the Spring 1999 MSRI program of the same name, covers broad areas such as topologic and combinatorial aspects of random matrix theory; scaling limits, universalities and phase transitions in matrix models; universalities for random polynomials; and applications to integrable systems. Its stress on the interaction between physics and mathematics will make it a welcome addition to the shelves of graduate students and researchers in both fields, as will its expository emphasis.

The theme of the book is the distribution and abundance of organisms in space and time. The core of the book lies in how local births and deaths are tied to emigration and immigration processes, and how environmental variability at different scales affects population dynamics with stochastic processes and spatial structure and shows how elementary analytical tools can be used to understand population fluctuations, synchrony, processes underlying range distributions and community structure and species coexistence. The book also shows how spatial population dynamics models can be used to understand life history evolution and aspects of evolutionary game theory. Although primarily based on analytical and numerical analyses of spatial population processes, data from several study systems are also dealt with.
