Physical Characteristics of Early Films as Aids to Identification: New expanded Edition

by Camille Bolt-Wellens

Any archivists who have held a piece of fi lm in their hands, wondering how to go about identifying it, recognize the true value of fi lm preservationist Harold Brown's work. In 1967 Brown delivered a pioneering lecture on the identification of early films at the annual Congress of the International Federation of Film Archives (FIAF) in East Berlin. Years of working with Britain's National Film Archive collections, and the close examination of thousands of nitrate prints of the silent period, made Brown a leading authority on early fi lm identification, and an unsurpassed model of methodological consciousness in the archival field. In 1990, FIAF published Brown's Physical Characteristics of Early Films as Aids to Identification, an updated version and a continuation of his 1967 lecture. This publication has long been archivists' trusted companion, constituting a concentrated encyclopedia on all the information that can be discovered or verified through aspects of the fi lm other than the actual projected image – such as perforation shapes; embossed and punched marks; stock manufacturers' and producers' edge marks; frame characteristics; title styles; and production serial numbers. It also included essays on key individual production companies of the silent era. Over the last 30 years, this manual – a basic typewritten 100-page volume (including 20 pages of black & white illustrations), with its easily recognizable red cover – has been an invaluable reference for fi lm archivists and scholars. However, as Brown himself acknowledged in the 1990 edition, the manual was far from definitive. Camille Blot-Wellens, the editor of this new, expanded edition of Brown's 1990 book, belongs to the new generation of researchers who have used Physical Characteristics extensively in their work and have gathered considerable new information on the subject. This new edition is the result of a project she initiated in 2014 with FIAF's support. Brown's original text is now augmented with new original research on key fi lm manufacturers and producers by Camille Bolt-Wellens and other leading archivists and researchers in the field. Richly illustrated (the book contains over 900 images, including 125 in full color), this new 336-page edition of Harold Brown's seminal manual will be welcomed by many, and will no doubt become a must-have working tool for many in the fi lm archiving and academic fields.

Physical Components of Tensors (Applied and Computational Mechanics)

by Wolf Altman Antonio Marmo Oliveira

Illustrating the important aspects of tensor calculus, and highlighting its most practical features, Physical Components of Tensors presents an authoritative and complete explanation of tensor calculus that is based on transformations of bases of vector spaces rather than on transformations of coordinates. Written with graduate students, professors, and researchers in the areas of elasticity and shell theories in mind, this text focuses on the physical and nonholonomic components of tensors and applies them to the theories. It establishes a theory of physical and anholonomic components of tensors and applies the theory of dimensional analysis to tensors and (anholonomic) connections. This theory shows the relationship and compatibility among several existing definitions of physical components of tensors when referred to nonorthogonal coordinates. The book assumes a basic knowledge of linear algebra and elementary calculus, but revisits these subjects and introduces the mathematical backgrounds for the theory in the first three chapters. In addition, all field equations are also given in physical components as well.Comprised of five chapters, this noteworthy text: Deals with the basic concepts of linear algebra, introducing the vector spaces and the further structures imposed on them by the notions of inner products, norms, and metrics Focuses on the main algebraic operations for vectors and tensors and also on the notions of duality, tensor products, and component representation of tensors Presents the classical tensor calculus that functions as the advanced prerequisite for the development of subsequent chapters Provides the theory of physical and anholonomic components of tensors by associating them to the spaces of linear transformations and of tensor products and advances two applications of this theory Physical Components of Tensors contains a comprehensive account of tensor calculus, and is an essential reference for graduate students or engineers concerned with solid and structural mechanics.

Physical Fundamentals of Oscillations: Frequency Analysis Of Periodic Motion Stability

by Leonid Chechurin Sergej Chechurin

The book introduces possibly the most compact, simple and physically understandable tool that can describe, explain, predict and design the widest set of phenomena in time-variant and nonlinear oscillations. The phenomena described include parametric resonances, combined resonances, instability of forced oscillations, synchronization, distributed parameter oscillation and flatter, parametric oscillation control, robustness of oscillations and many others. Although the realm of nonlinear oscillations is enormous, the book relies on the concept of minimum knowledge for maximum understanding. This unique tool is the method of stationarization, or one frequency approximation of parametric resonance problem analysis in linear time-variant dynamic systems. The book shows how this can explain periodic motion stability in stationary nonlinear dynamic systems, and reveals the link between the harmonic stationarization coefficients and describing functions. As such, the book speaks the language of control: transfer functions, frequency response, Nyquist plot, stability margins, etc. An understanding of the physics of stability loss is the basis for the design of new oscillation control methods for, several of which are presented in the book. These and all the other findings are illustrated by numerical examples, which can be easily reproduced by readers equipped with a basic simulation package like MATLAB with Simulink. The book offers a simple tool for all those travelling through the world of oscillations, helping them discover its hidden beauty. Researchers can use the method to uncover unknown aspects, and as a reference to compare it with other, for example, abstract mathematical means. Further, it provides engineers with a minimalistic but powerful instrument based on physically measurable variables to analyze and design oscillatory systems.
