Radical Passivity


Book Description

Radical Passivity examines the notion of passivity in the work of Levinas, Blanchot, and Agamben, three thinkers of exceptional intellectual privacy whose writings have decidedly altered the literary and philosophical cultures of our era. Placing their use of passivity in the context of Heidegger and Kant, Wall argues that any philosophical understanding of Levinas's ethics, Blanchot's aesthetics, or Agamben's community must begin with an understanding of a "logic" of passivity that in fact originates (in the modern era at least) in Kant's analysis of the transcendental schema.




Passivity-based Control of Euler-Lagrange Systems


Book Description

The essence of this work is the control of electromechanical systems, such as manipulators, electric machines, and power converters. The common thread that links together the results presented here is the passivity property, which is at present in numerous electrical and mechanical systems, and which has great relevance in control engineering at this time. Amongst other topics, the authors cover: Euler-Lagrange Systems, Mechanical Systems, Generalised AC Motors, Induction Motor Control, Robots with AC Drives, and Perspectives and Open Problems. The authors have extensive experience of research and application in the field of control of electromechanical systems, which they have summarised here in this self-contained volume. While written in a strictly mathematical way, it is also elementary, and will be accessible to a wide-ranging audience, including graduate students as well as practitioners and researchers in this field.




Passivity-Based Control and Estimation in Networked Robotics


Book Description

Highlighting the control of networked robotic systems, this book synthesizes a unified passivity-based approach to an emerging cross-disciplinary subject. Thanks to this unified approach, readers can access various state-of-the-art research fields by studying only the background foundations associated with passivity. In addition to the theoretical results and techniques, the authors provide experimental case studies on testbeds of robotic systems including networked haptic devices, visual robotic systems, robotic network systems and visual sensor network systems. The text begins with an introduction to passivity and passivity-based control together with the other foundations needed in this book. The main body of the book consists of three parts. The first examines how passivity can be utilized for bilateral teleoperation and demonstrates the inherent robustness of the passivity-based controller against communication delays. The second part emphasizes passivity’s usefulness for visual feedback control and estimation. Convergence is rigorously proved even when other passive components are interconnected. The passivity approach is also differentiated from other methodologies. The third part presents the unified passivity-based control-design methodology for multi-agent systems. This scheme is shown to be either immediately applicable or easily extendable to the solution of various motion coordination problems including 3-D attitude/pose synchronization, flocking control and cooperative motion estimation. Academic researchers and practitioners working in systems and control and/or robotics will appreciate the potential of the elegant and novel approach to the control of networked robots presented here. The limited background required and the case-study work described also make the text appropriate for and, it is hoped, inspiring to students.




The Concept of Passivity in Husserl's Phenomenology


Book Description

Building upon Husserl’s challenge to oppositions such as those between form and content and between constituting and constituted, The Concept of Passivity in Husserl’s Phenomenology construes activity and passivity not as reciprocally exclusive terms but as mutually dependent moments of acts of consciousness. The book outlines the contribution of passivity to the constitution of phenomena as diverse as temporal syntheses, perceptual associations, memory fulfillment and cross-cultural communication. The detailed study of the phenomena of affection, forgetting, habitus and translation sets out a distinction between three meanings of passivity: receptivity, sedimentation or inactuality and alienation. Husserl’s texts are interpreted as defending the idea that cultural crises are not brought to a close by replacing passivity with activity but by having more of both.




Passivity and Protection of Metals Against Corrosion


Book Description

Considerable progress has been made in the past 20 years toward understanding the basic mechanisms of corrosion, and the application of this knowledge to its control. From the very beginning, educational institutions and industrial research laboratories have contributed greatly toward determining and elucidating the fundamental principles of corrosion reactions. Some of the basic principles involved in cor rosion of metals can be credited to early investigators. Michael Faraday in 1830-1840 studied the relationship between the quantity of a metal dissolved and the electric current which was produced by this reaction. He also proposed that the passivation of iron was through the formation of a film and that the dissolution of a metal was electro chemical in nature. Sir Humphrey Davy in 1824 worked out the funda mentals of galvanic corrosion of ships' hulls and applied sacrificial zinc anodes to protect them from sea water corrosion. Richard Arlie in 1847 demonstrated that corrosion produced by oxygen at the surface of iron in a flowing stream generated a current. With the fundamental knowledge available to him from these early investigators, Willis Rodney Whitney developed and expressed, in its most useful form, one of the basic scientific principles which provides modern corrosion specialists with a fundamental basis of corrosion control. Dr. Whitney concluded that corrosion of iron is electrochemical, and that the rate is simply a function of the electromotive force and resistance of the circuit.




Half-Lived Life


Book Description

“So this is my life? What happened to the person I thought I might be at this stage of the game? Where did that person go? Why am I feeling like I’m just treading water, trying to stay one step ahead of my bills and obligations. Anyway, I’m just too tired at this point to try to figure out where that other person went. But I sure expected to be living a different life than this one.” Most people in their forties, fifties, and beyond catch themselves saying something similar to this. Everyone has a mental image of the person they want to be, but few of us actually fulfill these wishes. Once people realize they are living a completely different life than they’d envisioned, they often think it is too late to change and carry on with the same old habits. Too many people settle for a half-lived life. Best-selling author John Lee has long been addressing the fallacy of this attitude in talks and workshops—and now he sets this program into book form. In The Half-Lived Life, he introduces and explains how passivity holds us hostage to old ways of doing things—and provides solutions on escaping this paralyzing state of mind, body, and spirit while increasing our emotional intelligence (EQ). He also shows the freedom to be gained via compassionate assertiveness—an outgrowth of setting boundaries and enforcing limits. Just as Lee’s seminars have successfully led many to find their authentic self in the second half of their life, so too will this book.




The Birth of Sense


Book Description

In The Birth of Sense, Don Beith proposes a new concept of generative passivity, the idea that our organic, psychological, and social activities take time to develop into sense. More than being a limit, passivity marks out the way in which organisms, persons, and interbodily systems take time in order to manifest a coherent sense. Beith situates his argument within contemporary debates about evolution, developmental biology, scientific causal explanations, psychology, postmodernism, social constructivism, and critical race theory. Drawing on empirical studies and phenomenological reflections, Beith argues that in nature, novel meaning emerges prior to any type of constituting activity or deterministic plan. The Birth of Sense is an original phenomenological investigation in the style of Maurice Merleau-Ponty, and it demonstrates that the French philosopher’s works cohere around the notion that life is radically expressive. While Merleau-Ponty’s early works are widely interpreted as arguing for the primacy of human consciousness, Beith argues that a pivotal redefinition of passivity is already under way here, and extends throughout Merleau-Ponty’s corpus. This work introduces new concepts in contemporary philosophy to interrogate how organic development involves spontaneous expression, how personhood emerges from this bodily growth, and how our interpersonal human life remains rooted in, and often thwarted by, domains of bodily expressivity.




L2 - Gain and Passivity Techniques in Nonlinear Control


Book Description

With respect to the first edition as Volume 218 in the Lecture Notes in Con trol and Information Sciences series the basic idea of the second edition has remained the same: to provide a compact presentation of some basic ideas in the classical theory of input-output and closed-loop stability, together with a choice of contributions to the recent theory of nonlinear robust and 1foo control and passivity-based control. Nevertheless, some parts of the book have been thoroughly revised and/or expanded, in order to have a more balanced presen tation of the theory and to include some of the new developments which have been taken place since the appearance of the first edition. I soon realized, how ever, that it is not possible to give a broad exposition of the existing literature in this area without affecting the spirit of the book, which is precisely aimed at a compact presentation. So as a result the second edition still reflects very much my personal taste and research interests. I trust that others will write books emphasizing different aspects. Major changes with respect to the first edition are the following: • A new section has been added in Chapter 2 relating L2-gain and passivity via scattering, emphasizing a coordinate-free, geometric, treatment. • The section on stability in Chapter 3 has been thoroughly expanded, also incorporating some recent results presented in [182J.




Passivity of Complex Dynamical Networks


Book Description

This book intends to introduce some recent results on passivity of complex dynamical networks with single weight and multiple weights. The book collects novel research ideas and some definitions in complex dynamical networks, such as passivity, output strict passivity, input strict passivity, finite-time passivity, and multiple weights. Furthermore, the research results previously published in many flagship journals are methodically edited and presented in a unified form. The book is likely to be of interest to university researchers and graduate students in Engineering and Mathematics who wish to study the passivity of complex dynamical networks.




Radical Passivity


Book Description

Levinas’s ethical metaphysics is essentially a meditation on what makes ethical agency possible – that which enables us to act in the interest of another, to put the well-being of another before our own. This line of questioning found its inception in and drew its inspiration from the mass atrocities that occurred during the Second World War. The Holocaust , like the Cambodian genocide, or those in Rwanda and Srebrenica, exemplifies what have come to be known as the ‘never again’ situations. After these events, we looked back each time, with varying degrees of incomprehension, horror, anger and shame, asking ourselves how we could possibly have let it all happen again. And yet, atrocity crimes are still rampant. After Rwanda (1994) and Bosnia-Herzegovina (1992–1995), came Kosovo (1999) and Darfur (2003). In our present-day world , hate crimes motivated by racial, sexual, or other prejudice, and mass hate such as genocide and terror, are on the rise (think, for example, of Burma, Zimbabwe, Sri Lanka and North Korea). A critical revaluation of the conditions of possibility of ethical agency is therefore more necessary than ever. This volume is committed to the possibility of ‘never again’. It is dedicated to all the victims – living and dead – of what Levinas calls the ‘sober, Cain-like coldness’ at the root of all crime against humanity , as much as every singular crime against another human being .
