Exploiting Nonlinear Behavior in Structural Dynamics

This book develops the theory of global attractors for a class of parabolic PDEs which includes reaction-diffusion equations and the Navier-Stokes equations, two examples that are treated in detail. A lengthy chapter on Sobolev spaces provides the framework that allows a rigorous treatment of existence and uniqueness of solutions for both linear time-independent problems (Poisson's equation) and the nonlinear evolution equations which generate the infinite-dimensional dynamical systems of the title. Attention then switches to the global attractor, a finite-dimensional subset of the infinite-dimensional phase space which determines the asymptotic dynamics. In particular, the concluding chapters investigate in what sense the dynamics restricted to the attractor are themselves 'finite-dimensional'. The book is intended as a didactic text for first year graduates, and assumes only a basic knowledge of Banach and Hilbert spaces, and a working understanding of the Lebesgue integral.

The current state of the art in cognitive robotics, covering the challenges of building AI-powered intelligent robots inspired by natural cognitive systems.A novel approach to building AI-powered intelligent robots takes inspiration from the way natural cognitive systems―in humans, animals, and biological systems―develop intelligence by exploiting the full power of interactions between body and brain, the physical and social environment in which they live, and phylogenetic, developmental, and learning dynamics. This volume reports on the current state of the art in cognitive robotics, offering the first comprehensive coverage of building robots inspired by natural cognitive systems. Contributors first provide a systematic definition of cognitive robotics and a history of developments in the field. They describe in detail five main approaches: developmental, neuro, evolutionary, swarm, and soft robotics. They go on to consider methodologies and concepts, treating topics that include c

Elastic structures, conceived as slender bodies able to transmit loads, have been studied by scientists and engineers for centuries. By the seventeenth century several useful theories of elastic structures had emerged, with applications to civil and mechanical engineering problems. In recent years improved mathematical tools have extended applications into new areas such as geomechanics and biomechanics. This book, first published in 1998, offers a critically filtered collection of the most significant theories dealing with elastic slender bodies. It includes mathematical models involving elastic structures, which are used to solve practical problems with particular emphasis on nonlinear problems. This collection of interesting and important problems in elastic structures will appeal to a broad range of scientists, engineers and graduate students working in the area of structural mechanics.

This introduction to the theory of Hamiltonian chaos outlines the main results in the field, and goes on to consider implications for quantum mechanics. The study of nonlinear dynamics, and in particular of chaotic systems, is one of the fastest growing and most productive areas in physics and applied mathematics. In its first six chapters, this timely book introduces the theory of classical Hamiltonian systems. The aim is not to be comprehensive but, rather, to provide a mathematical trunk from which the reader will be able to branch out. The main focus is on periodic orbits and their neighbourhood, as this approach is especially suitable as an introduction to the implications of the theory of chaos in quantum mechanics, which are discussed in the last three chapters.

This volume emphasizes fundamental concepts, both on the development of mathematical models of fracture phenomena and on the analysis of these models. Cases involving stress waves impinging on cracks, tractions suddenly applied to the faces of cracks, and rapid crack growth and arrest are considered in detail. Most of the work is concerned with the behavior of nominally elastic materials, but available results on elastic-plastic and elastic-viscoplastic materials are included. Connections to experimental results and to applications in structural mechanics, seismology, and materials science are noted whenever possible.

This book is for those who are not just interested in the ways humans have harmfully altered their environment, but instead wish to learn why the many governmental policies in place to curb such behavior have been unsuccessful. Since humans began to exploit natural resources for their own economic ends, we have ignored a central principle: nature and humans are not separate, but are a unified, interconnected system in which neither is superior to the other. Policy must reflect this reality. We failed to follow this principle in exploiting natural capital without expecting to pay any price, and in hurriedly adopting environmental laws and policies that reflected how we wanted nature to work instead of how it does work. This study relies on more accurate models for how nature works and humans behave. These models suggest that environmental laws should be consistent with the laws of nature.

Mechanical behavior of materials is then discussed in depth, covering elastic deformation, viscoelasticity and time-dependent behavior, multiaxial loading and complex stress states, yielding and failure theories, and fracture mechanics. The final section on clinical aspects of medical devices provides crucial information on FDA regulatory issues and presents case studies in four key clinical areas: orthopedics, cardiovascular devices, dentistry and soft tissue implants. Each chapter ends with a list of topical questions, making this an ideal course textbook f

The introduction of numerical methods, particularly finite element (FE) analysis, represents a significant advance in metal forming operations. Numerical methods are used increasingly to optimize product design and deal with problems in metal forging, rolling, and extrusion processes. Metal Forming Analysis, first published in 2001, describes the most important numerical techniques for simulating metal forming operations. The first part of the book describes principles and procedures and includes numerous examples and worked problems. The remaining chapters focus on applications of numerical analysis to specific forming operations. Most of these results are drawn from the authors' research in the areas of metal testing, sheet metal forming, forging, extrusion, and similar operations. Sufficient information is presented so that readers can understand the nonlinear finite element method as applied to forming problems without a prior background in structural finite element analysis.

This explores the question of when and why violence by and against new religious cults erupts and whether and how such dramatic conflicts can be foreseen, managed and averted. The authors, leading international experts on religious movements and violent behavior, focus on the four major episodes of cult violence during the last decade: the tragic conflagration that engulfed the Branch Davidians in Waco, Texas; the deadly sarin gas attack by the Aum Shinrikyo in Tokyo; the murder-suicides by the Solar Temple in Switzerland and Canada; and the collective suicide by the members of Heaven's Gate. They explore the dynamics leading to these dramatic episodes in North America, Europe, and Asia, and offer insights into the general relationship between violence and religious cults in contemporary society. The authors conclude that these events usually involve some combination of internal and external dynamics through which a new religious movement and society become polarized.

This book provides a comprehensive and self-contained overview of recent progress in nonequilibrium statistical mechanics, in particular, the discovery of fluctuation relations and other time-reversal symmetry relations. The significance of these advances is that nonequilibrium statistical physics is no longer restricted to the linear regimes close to equilibrium, but extends to fully nonlinear regimes. These important new results have inspired the development of a unifying framework for describing both the microscopic dynamics of collections of particles, and the macroscopic hydrodynamics and thermodynamics of matter itself. The book discusses the significance of this theoretical framework in relation to a broad range of nonequilibrium processes, from the nanoscale to the macroscale, and is essential reading for researchers and graduate students in statistical physics, theoretical chemistry and biological physics.

This book sets out a generative structuralist conception of general theoretical sociology; its philosophy, its problems, and its methods. The field is defined as a comprehensive research tradition with many intersecting subtraditions that share conceptual components. The focus is on formalization and unification as processes that can help advance the state of theory today. An integrative philosophy of the field is set out in terms of a process worldview, with a focus on generativity in explanation and a conception of the structure of theories as hierarchical meaning control systems. This philosophy is implemented in two phases. In the first phase, Professor Fararo defines the core problems of theoretical sociology in the context of setting out and illustrating the logic of a nonlinear dynamical social systems framework. A critical analysis of the outcome of this phase then leads, in the second phase, to formal treatments of action principles and structural analysis. A variety of tradit

Terence Mills' best-selling graduate textbook provides detailed coverage of research techniques and findings relating to the empirical analysis of financial markets. In its previous editions it has become required reading for many graduate courses on the econometrics of financial modelling. This third edition, co-authored with Raphael Markellos, contains a wealth of material reflecting the developments of the last decade. Particular attention is paid to the wide range of nonlinear models that are used to analyse financial data observed at high frequencies and to the long memory characteristics found in financial time series. The central material on unit root processes and the modelling of trends and structural breaks has been substantially expanded into a chapter of its own. There is also an extended discussion of the treatment of volatility, accompanied by a new chapter on nonlinearity and its testing.

Time series econometrics is a rapidly evolving field. Particularly, the cointegration revolution has had a substantial impact on applied analysis. Hence, no textbook has managed to cover the full range of methods in current use and explain how to proceed in applied domains. This gap in the literature motivates the present volume. The methods are sketched out, reminding the reader of the ideas underlying them and giving sufficient background for empirical work. The treatment can also be used as a textbook for a course on applied time series econometrics. Topics include: unit root and cointegration analysis, structural vector autoregressions, conditional heteroskedasticity and nonlinear and nonparametric time series models. Crucial to empirical work is the software that is available for analysis. New methodology is typically only gradually incorporated into existing software packages. Therefore a flexible Java interface has been created, allowing readers to replicate the applications and

Mechanics of Solids and Materials intends to provide a modern and integrated treatment of the foundations of solid mechanics as applied to the mathematical description of material behavior. The 2006 book blends both innovative (large strain, strain rate, temperature, time dependent deformation and localized plastic deformation in crystalline solids, deformation of biological networks) and traditional (elastic theory of torsion, elastic beam and plate theories, contact mechanics) topics in a coherent theoretical framework. The extensive use of transform methods to generate solutions makes the book also of interest to structural, mechanical, and aerospace engineers. Plasticity theories, micromechanics, crystal plasticity, energetics of elastic systems, as well as an overall review of math and thermodynamics are also covered in the book.

A funny and whimsical picture book about an ordinary family day, told through a bird family, from 2022 Astrid Lindgren Memorial Award recipient Eva Lindstroem. "Wash your beaks, it's time for lunch-flies again today," says Dad. After lunch the young birds get sent off to play-they sing, hunt mosquitos, compare leg size and poke grubs.This is how birds spend a day. Eva Lindstroem reflects the familiar and the absurd in human behavior through this funny bird family. We all recognize the family dynamics of bickering over fried mosquitos and worm pie-only the youngest is allowed to pick out the worms.Toddlers will recognize key moments in a perfectly down to earth day-play, mealtimes, stretching boundaries and sleep. With dry observations of human family behavior that adults will enjoy, this is a picture book to make all the family laugh and to read aloud together. Expressive faces, hilarious hairstyles, Dad's great cooking, and a sister and brother's everyday conversation combine in a hea

Analytical Mechanics, first published in 1999, provides a detailed introduction to the key analytical techniques of classical mechanics, one of the cornerstones of physics. It deals with all the important subjects encountered in an undergraduate course and prepares the reader thoroughly for further study at graduate level. The authors set out the fundamentals of Lagrangian and Hamiltonian mechanics early on in the book and go on to cover such topics as linear oscillators, planetary orbits, rigid-body motion, small vibrations, nonlinear dynamics, chaos, and special relativity. A special feature is the inclusion of many 'e-mail questions', which are intended to facilitate dialogue between the student and instructor. Many worked examples are given, and there are 250 homework exercises to help students gain confidence and proficiency in problem-solving. It is an ideal textbook for undergraduate courses in classical mechanics, and provides a sound foundation for graduate study.

Wave Interactions and Fluid Flows is a coherent, up-to-date and comprehensive account of theory and experiment on wave-interaction phenomena, both in fluids at rest and in shear flows. On the one hand, this includes water waves, internal waves, their evolution and interaction and associated wave-driven mean flows; on the other, phenomena of nonlinear hydrodynamic stability, especially those leading to the onset of turbulence. Close similarities - and crucial differences - exist between these two classes of phenomena and their treatment in this single study provides a particularly valuable bridge between more specialised, but related, disciplines. As a result, this unique book will appeal to researchers and graduate students of fluid mechanics in its widest sense, including the study of wave-interaction phenomena in such diverse fields as meteorology, aeronautical and hydraulic engineering, optics, solar physics and population dynamics. Dr Craik is an active researcher of long-standing

A ship is a flexible structure that moves bodily and distorts when it encounters waves. This behaviour is potentially dangerous and it must therefore be predicted as a necessary part of ship design. Hitherto the theory of ship structures has had to employ simplifying assumptions, and the dynamical theory has been founded largely on the assumption of rigidity. This book, however, shows how the wave responses of a ship can be calculated using linear dynamics. This general treatment adapts the techniques of structural theory, hydrodynamics, oceanography and statistical theory to the needs of naval architecture. In a radically new departure the authors unify these various techniques in their systematic use of dynamical theory. The principles are applicable to offshore structures in general as well as to ships.

Foundations of Dynamic Economic Analysis presents a modern and thorough exposition of the fundamental mathematical formalism used to study optimal control theory, i.e., continuous time dynamic economic processes, and to interpret dynamic economic behavior. The style of presentation, with its continual emphasis on the economic interpretation of mathematics and models, distinguishes it from several other excellent texts on the subject. This approach is aided dramatically by introducing the dynamic envelope theorem and the method of comparative dynamics early in the exposition. Accordingly, motivated and economically revealing proofs of the transversality conditions come about by use of the dynamic envelope theorem. Furthermore, such sequencing of the material naturally leads to the development of the primal-dual method of comparative dynamics and dynamic duality theory, two modern approaches used to tease out the empirical content of optimal control models.

Innovation is a systemic phenomenon in which institutions, such as firms, government entities and public policy incentives, interact in complex ways. Targeting specific sectors of an economy in order to improve the competitiveness and capabilities of domestic firms, interventionist innovation policies can result in the structural transformation of host economies. Numerous examples exist of such policies working successfully in emerging economies and they can be applied to any economic sector, although they are commonly associated with highly innovative industries such ICT, biotechnology and nanotechnology. Innovation Systems, Policy and Management describes how institutions and markets can best be structured in order to promote innovation in key economic sectors. Bringing together some of the leading figures in industrial policy and the economics of innovation and entrepreneurship, this book encourages the reader to think in terms of systems and business dynamics when analysing innovat

A New York Times BestsellerAn audacious, irreverent investigation of human behavior—and a first look at a revolution in the makingOur personal data has been used to spy on us, hire and fire us, and sell us stuff we don’t need. InDataclysm, Christian Rudder uses it to show us who we truly are. For centuries, we’ve relied on polling or small-scale lab experiments to study human behavior. Today, a new approach is possible. As we live more of our lives online, researchers can finally observe us directly, in vast numbers, and without filters. Data scientists have become the new demographers.In this daring and original book, Rudder explains how Facebook "likes" can predict, with surprising accuracy, a person’s sexual orientation and even intelligence; how attractive women receive exponentially more interview requests; and why you must have haters to be hot. He charts the rise and fall of America’s most reviled word through Google Search and examines the new dynamics of coll

Productive employment opportunities constitute the primary ingredient of economic transformation and inclusive growth. This volume examines India's development experience in the sphere of labour, employment, structural change and institutional challenges in the recent past. The contributors have extended the boundaries of contemporary debate in a variety of ways by undertaking fairly detailed empirical analysis of selected aspects of growth and employment change in India. They uncover the recent patterns of change, between and within sectors over time that challenges popular beliefs and understanding of employment growth in India. Analysis of population ageing, gender discrimination, impact of labour regulation; institutional analysis; dynamics of judicial interpretation of laws protecting workers in the years of economic liberalisation among others have enriched the content. The volume contributes to our knowledge of India's labour market and sheds light on employment challenges in an

Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons. This book is a comprehensive survey of static topological solitons and their dynamical interactions. Particular emphasis is placed on the solitons which satisfy first-order Bogomolny equations. For these, the soliton dynamics can be investigated by finding the geodesics on the moduli space of static multi-soliton solutions. Remarkable scattering processes can be understood this way. The book starts with an introduction to classical field theory, and a survey of several mathematical techniques useful for understanding many types of topological soliton. Subsequent chapters explore key examples of solitons in one, two, three and four dimensions. The final chapter discusses the unstable sphaleron solutions which exist in several
