Self-propelled objects (particles, droplets) are autonomous agents that can convert energy from the environment into motion. These motions include nonlinear behaviour such as oscillations, synchronization, bifurcation, and pattern formation. In recent years, there has been much interest in self-propelled objects for their potential role in mass transport or their use as carriers in confined spaces. An improved understanding of self-organized motion has even allowed researchers to design objects for specific motion. This book gives an overview of the principles of self-propelled motion in chemical objects (particles, droplets) far from their thermodynamic equilibrium, at various spatial scales. Theoretical aspects, the characteristics of the motion and the design procedures of such systems are discussed from the viewpoint of nonlinear dynamics and examples of applications for these nonlinear systems are provided. This book is suitable for researchers and graduate students interested in physical and theoretical chemistry as well as soft matter.

This book offers a rigorous and self-contained presentation of stochastic integration and stochastic calculus within the general framework of continuous semimartingales. The main tools of stochastic calculus, including Itô’s formula, the optional stopping theorem and Girsanov’s theorem, are treated in detail alongside many illustrative examples. The book also contains an introduction to Markov processes, with applications to solutions of stochastic differential equations and to connections between Brownian motion and partial differential equations. The theory of local times of semimartingales is discussed in the last chapter. Since its invention by Itô, stochastic calculus has proven to be one of the most important techniques of modern probability theory, and has been used in the most recent theoretical advances as well as in applications to other fields such as mathematical finance. Brownian Motion, Martingales, and Stochastic Calculus provides a strong theoretical background to the reader interested in such developments. Beginning graduate or advanced undergraduate students will benefit from this detailed approach to an essential area of probability theory. The emphasis is on concise and efficient presentation, without any concession to mathematical rigor. The material has been taught by the author for several years in graduate courses at two of the most prestigious French universities. The fact that proofs are given with full details makes the book particularly suitable for self-study. The numerous exercises help the reader to get acquainted with the tools of stochastic calculus.

An introductory reference covering the devices, simulations and limitations in the control of servo systems Linking theoretical material with real-world applications, this book provides a valuable introduction to motion system design. The book begins with an overview of classic theory, its advantages and limitations, before showing how classic limitations can be overcome with complete system simulation. The ability to efficiently vary system parameters (such as inertia, friction, dead-band, damping), and quickly determine their effect on performance, stability, efficiency, is also described. The author presents a detailed review of major component characteristics and limitations as they relate to system design and simulation. The use of computer simulation throughout the book will familiarize the reader as to how this contributes to efficient system design, how it avoids potential design flaws and saves both time and expense throughout the design process. The comprehensive coverage of topics makes the book ideal for professionals who need to apply theory to real-world situations, as well as students who wish to enhance their understanding of the topic. • Covers both theory and practical information at an introductory level, allowing readers to advance to further topics having obtained a strong grounding in the subject • Provides a connection between classic servo technology and the evolution of computer control and simulation • VisSim demonstration material available on an accompanying website enabling readers to experiment with system examples

Edgar Cayce on Vibrations

Science caught up with the psychic readings of Edgar Cayce when it proved that all of materiality - consisting of atoms and therefore protons, neutrons, and electrons - is energy in motion. Everything is a vibration. Even the body's five senses operate through the use of vibrations. The Cayce readings suggested that vibrations were also associated with healing, consciousness, and even locations. In fact, the Cayce information presents the premise that all of life in every dimension is actually just different manifestations of the One Force - the Force that moved all of Creation into being. Therefore, all vibration is ultimately that One Force manifesting in the material world in a variety of ways. Todeschi's latest title explores how everything from consciousness to the material is connected to vibration, and how we continue to create and shape our world through the vibrations all around us. Vibrations are essentially spirit in motion and our thoughts and actions affect our life and the way we are living.

Ritual Textuality

A classic question in studies of ritual is how ritual performances achieve-or fail to achieve-their effects. In this pathbreaking book, Matt Tomlinson argues that participants condition their own expectations of ritual success by interactively creating distinct textual patterns of sequence, conjunction, contrast, and substitution. Drawing on long-term research in Fiji, Ritual Textuality presents in-depth studies of each of these patterns, taken from a wide range of settings: a fiery, soul-saving Pentecostal crusade; relaxed gatherings at which people drink the narcotic beverage kava; deathbeds at which missionaries eagerly await the signs of good Christians' "happy deaths"; and the monologic pronouncements of a military-led government determined to make the nation speak in a single voice. In each of these cases, Tomlinson also examines the broad ideologies of motion which frame participants' ritual actions, such as Pentecostals' beliefs that effective worship requires ecstatic movement like jumping, dancing, and clapping, and nineteenth-century missionaries' insistence that the journeys of the soul in the afterlife should follow a new path. By approaching ritual as an act of "entextualization"-in which the flow of discourse is turned into object-like texts-while analyzing the ways people expect words, things, and selves to move in performance, this book presents a new and compelling way to understand the efficacy of ritual action.

Diverse musical cultures of migrant communities have existed in Europe for centuries. This volume will focus on different musical traditions and practices, but also raises questions such as: How are musical traditions of migrants integrated into education and public music? Can music facilitate transcultural dialogue? And to what extent does the practice and performance of music reassert cultural traditions in a foreign environment? Answers to those questions as well as a review on what can be observed in twenty-first century Europe are gathered in various thematic sections; model projects will provide a practical insight into the life and work with music of migrant and minority cultures in Europe. This volume results from a project of the European Music Council, a non-governmental network of music organizations.

Words in Motion

On the premise that words have the power to make worlds, each essay in this book follows a word as it travels around the globe and across time. Scholars from five disciplines address thirteen societies to highlight the social and political life of words in Asia, Europe, and the Middle East, from the mid-nineteenth century to the present. The approach is consciously experimental, in that rigorously tracking specific words in specific settings frequently leads in unexpected directions and alters conventional depictions of global modernity. Such words as security in Brazil, responsibility in Japan, community in Thailand, and hijāb in France changed the societies in which they moved even as the words were changed by them. Some words threatened to launch wars, as injury did in imperial Britain’s relations with China in the nineteenth century. Others, such as secularism, worked in silence to agitate for political change in twentieth-century Morocco. Words imposed or imported from abroad could be transformed by those who wielded them to oppose the very powers that first introduced them, as happened in Turkey, Indonesia, and the Philippines. Taken together, this selection of fourteen essays reveals commonality as well as distinctiveness across modern societies, making the world look different from the interdisciplinary and transnational perspective of “words in motion.” Contributors.

Selected Aspects of Fractional Brownian Motion

Fractional Brownian motion (fBm) is a stochastic process which deviates significantly from Brownian motion and semimartingales, and others classically used in probability theory. As a centered Gaussian process, it is characterized by the stationarity of its increments and a medium- or long-memory property which is in sharp contrast with martingales and Markov processes. FBm has become a popular choice for applications where classical processes cannot model these non-trivial properties; for instance long memory, which is also known as persistence, is of fundamental importance for financial data and in internet traffic. The mathematical theory of fBm is currently being developed vigorously by a number of stochastic analysts, in various directions, using complementary and sometimes competing tools. This book is concerned with several aspects of fBm, including the stochastic integration with respect to it, the study of its supremum and its appearance as limit of partial sums involving stationary sequences, to name but a few. The book is addressed to researchers and graduate students in probability and mathematical statistics. With very few exceptions (where precise references are given), every stated result is proved.
