Figures Of Slippage And Oscillation

Determination of the spontaneous oscillations of a wing or tail unit entail many difficulties, both the mathematical determination and the determination by static wing oscillation tests being far from successful and flight tests involving very great risks. The present paper gives a method developed at the Junkers Airplane Company by which the critical velocity with respect to spontaneous oscillations of increasing amplitude can be ascertained in flight tests without undue risks, the oscillation of the surface being obtained in the tests by the application of an external force.

Develops the sustained, relational, dynamic, and reflective attention demanded by Gertrude Stein’s novel into a theory of reading and critical analysis. Arguing that Gertrude Stein’s monumental novel The Making of Americans models a radically aesthetic relation to the world, E. L. McCallum demonstrates how the novel teaches us to read differently, unmaking our habits of reading. Each of the chapters works through close readings of Stein’s text and a philosophical interlocutor to track a series of theoretical questions: what forms queer time, what are the limits of story, how do we feel emotion, how can we agree on a shared reality if interpretation and imagination intervene, and how do particular media shape how we convey this rich experience? The formally innovative agenda and epistemological drive of Stein’s novel stages rich thought experiments that bear on questions that are central to some of the most vibrant conversations in literary studies today. In the midst of ongoing debates about the practices of reading, the difficulty of reading, and even the impossibility of reading, the moment has come to have a fuller critical engagement with this landmark novel. This book shows how.

Polymer Processing Instabilities: Control and Understanding offers a practical understanding of the various flows that occur during the processing of polymer melts. The book pays particular attention to flow instabilities that affect the rate of production and the methods used to prevent and eliminate flow instabilities in order to increase product

New Volume 1B edition of the classic text, now more than ever tailored to meet the needs of the struggling student.

This book presents a comprehensive description of the physics of free-electron lasers starting from the fundamentals and proceeding through detailed derivations of the equations describing electron trajectories, and spontaneous and stimulated emission. Linear and nonlinear analyses are described, as are detailed explanations of the nonlinear simulation of a variety of configurations including amplifiers, oscillators, self-amplified spontaneous emission, high-gain harmonic generation, and optical klystrons. Theory and simulation are anchored using comprehensive comparisons with a wide variety of experiments.

Continuing the themes that have been addressed in The Humanities in Architectural Design and The Cultural Role of Architecture, this book illustrates the important role that a contradiction between form and function plays in compositional strategies in architecture. The contradiction between form and function is seen as a device for poetic expression, for the expression of ideas, in architecture. Here the role of the terms "form" and "function" are analyzed throughout the history of architecture and architectural theory, from Vitruvius to the present, with particular emphasis on twentieth-century functionalism. Historical examples are given from Ancient, Classical, Islamic, Christian, Byzantine, Gothic, Renaissance, Mannerist, and Neoclassical architecture, and from movements in the twentieth century to the present. In addition philosophical issues such as lineamenti, Vorstellung, différance, dream construction, deep structure and surface structure, topology theory, self-generation, and immanence are explored in relation to the compositions and writings of architects throughout history. This book contributes to the project of re-establishing architecture as a humanistic discipline, to re-establish an emphasis on the expression of ideas, and on the ethical role of architecture to engage the intellect of the observer and to represent human identity.

All aspects of our lives, industry, health, travel and leisure, are utterly reliant on rubber materials, yet typically this notion rarely occurs to us. Increasingly, greater demands are made on elastomeric compounds and we seek elevated performance in terms of improved physical and chemical properties. In particular, we have come to expect rubber components (tyres, vibration isolators, seals etc) to exhibit exceptional wear and fatigue resistance, often at elevated temperatures. Unsurprisingly then, the emphasis in characterising isochoric materials has shifted significantly away from understanding and modelling hyperelastic material behaviour, to a position where we can confi dently design and manufacture rubber components having the functionality and resilience to meet the dynamic loading and harsh environmental conditions that are prevalent today. In consequence, state-of-the-art technology in terms of dynamic response and fatigue resistance are strongly represented here along with numerous insights into advanced elastomers used in novel applications. This development is not at the expense of research devoted to current test procedures and the constitutive equations and algorithms that underpin finite element methods. As a result, Constitutive Models for Rubber VII is not only essential reading for undergraduates, postgraduates, academics and researchers working in the discipline, but also for all those designers and engineers involved in the improvement of machines and devices by introducing new and novel elastomers possessing elevated properties.
