Around the world, the aftershocks of an economic crisis brought on by neoliberal economics and aided by the austerity measures of governments continue to be felt. Yet, we are told that there is simply no alternative; that our current form of capitalism is here to stay. This book sets out to challenge this statement by arguing that the long-neglected theory of libertarian socialism can help us understand more fully the problems of our late modern society, as well as offering a plausible and attractive alternative. Matt Dawson draws upon classical and contemporary sociology to argue that individualization and late modernity are best realised in the associational forms advocated by theorists such as Emile Durkheim through discussing themes such as: everyday life, the state, economic democracy and social movements. Dawson encourages the reader to think anew about our contemporary concern with individualization, and how this is realised politically.

Recent advancements in Lyapunov-based design and analysis techniques have applications to a broad class of engineering systems, including mechanical, electrical, robotic, aerospace, and underactuated systems. This book provides a practical yet rigorous development of nonlinear, Lyapunov-based tools and their use in the solution of control-theoretic problems. Rich in motivating examples and new design techniques, the text balances theoretical foundations and real-world implementation.

Features include:

* Control designs for a broad class of engineering systems

* Presentation of adaptive and learning control methods for uncertain nonlinear systems

* Experimental testbed descriptions and results that guide the reader toward techniques for further research

* Development of necessary mathematical background in each chapter; additional mathematical prerequisites contained in two appendices

Intended for readers who have some knowledge of undergraduate systems theory, the book includes a wide range of applications making it suitable for an extensive audience. Graduate students and researchers in control systems, robotics, and applied mathematics, as well as professional engineers will appreciate the work s combination of theoretical underpinnings and current and emerging engineering applications."

Lyapunov-Based Control of Robotic Systems describes nonlinear control design solutions for problems that arise from robots required to interact with and manipulate their environments. Since most practical scenarios require the design of nonlinear controllers to work around uncertainty and measurement-related issues, the authors use Lyapunov's direct method as an effective tool to design and analyze controllers for robotic systems. After describing the evolution of real-time control design systems and the associated operating environments and hardware platforms, the book presents a host of standard control design tools for robotic systems using a common Lyapunov-based framework. It then discusses several problems in visual servoing control, including the design of homography-based visual servo control methods and the classic structure from motion problem. The book also deals with the issues of path planning and control for manipulator arms and wheeled mobile robots. With a focus on the emerging research area of human machine interaction, the final chapter illustrates the design of control schemes based on passivity such that the machine is a net energy sink. Including much of the authors' own research work in controls and robotics, this book facilitates an understanding of the application of Lyapunov-based control design techniques to up-and-coming problems in robotics.

An authoritative collection of recent breakthroughs in Parkinson's Disease (PD) research, Parkinson's Disease: Genetics and Pathogenesis spans key findings on the mechanisms of neurodegeneration and the role of specific genes that may lead to improved therapies for PD. The book reviews the major aspects of the disease including motoric and pathologic features, autonomic dysfunction, sleep disorders, and neuropsychiatric manifestations. It also provides an in-depth review of genetic considerations. With contributions by recognized experts on the topic, emphasis is placed on pathogenesis, experimental models, future therapeutic opportunities, and research trends affecting the field.

It also addresses procedures and issues in computed-torque, robust, adaptive, neural network, and force control. New chapters relay practical information on commercial robot manipulators and devices and cutting-edge methods in neural network control.

This concise introduction to cognitive science provides undergraduate and graduate students with the theoretical foundations of classical and connectionist cognitive science to explain the and teach the underlying unity of the field. "Understanding Cognitive Science" approaches cognitive science through the "tri-level hypothesis" which assumes that the diverse fields of cognitive science should not be studied together, but also in constant communication with each other, rather than as a collection of otherwise only cognitively friendly disciplines.

It approaches cognitive science through the 'tri-level hypothesis' which assumes that the diverse fields of cognitive science should not be studied together, but also in constant communication with each other, rather than as a collection of otherwise only cognitively friendly disciplines.

Assuming the foundational idea that cognition is information processing, Understanding Cognitive Science describes different levels of analysis through the discussion of processes such as language, learning, vision, and memory. It closes by analyzing the anti-computational arguments against the traditional cognitive science orthodoxy, examining the mind as a dynamic system rather than a computer and picturing connectionism as an alternative to computationalism. The coverage of these debates serves to define the current discipline of cognitive science and to overview the controversies surrounding the field.

Influenced most notably by Emile Durkheim and Zygmunt Bauman, Dawson outlines how this long neglected stream of socialist theory can help us more fully understand, and possibly move beyond, the problems of neoliberalism and our conceptions of political individualism.
