Download or read book Randomly Moving Particles written by Andrew Motion and published by University of Pittsburgh Press. This book was released on 2021-03-23 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Randomly Moving Particles is built from two long poems that form its opening and close, connected by three shorter pieces. The title poem, in a kaleidoscope of compelling scenes, engages with subjects that include migration, placement, loss, space exploration, and current British and American politics. It is a clarifying action and reaction between terra and solar system, mundanity and possibility, taking us from the grit of road surfaces to the distant glimpses of satellites. The final poem, “How Do the Dead Walk,” combines mythic reach with acute observation of the familiar, in order to address issues of contemporary violence. It is altogether more dreamlike, even in its tangibly military moments, grasping as it does at phantoms and intermediate plains. Andrew Motion’s expansive new poetry collection is direct in its emotional appeal and ambitious in its scope, all while retaining the cinematic vision and startling expression that so freshly lit the lines of his last, Essex Clay.
Download or read book Markov Random Flights written by Alexander D. Kolesnik and published by CRC Press. This book was released on 2021-01-04 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Markov Random Flights is the first systematic presentation of the theory of Markov random flights in the Euclidean spaces of different dimensions. Markov random flights is a stochastic dynamic system subject to the control of an external Poisson process and represented by the stochastic motion of a particle that moves at constant finite speed and changes its direction at random Poisson time instants. The initial (and each new) direction is taken at random according to some probability distribution on the unit sphere. Such stochastic motion is the basic model for describing many real finite-velocity transport phenomena arising in statistical physics, chemistry, biology, environmental science and financial markets. Markov random flights acts as an effective tool for modelling the slow and super-slow diffusion processes arising in various fields of science and technology. Features: Provides the first systematic presentation of the theory of Markov random flights in the Euclidean spaces of different dimensions. Suitable for graduate students and specialists and professionals in applied areas. Introduces a new unified approach based on the powerful methods of mathematical analysis, such as integral transforms, generalized, hypergeometric and special functions. Author Alexander D.

Download or read book Radiation Trapped in the Earth s Magnetic Field written by Billy McCormac and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 903 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures presented at the Advanced Study Institute, 'Radiation Trapped in the Earth's Magnetic Field' which was held at the Bergen Tekniske Skole, Bergen, Norway, during the period August 16 through September 3, 1965. Approximately one-third of the time was devoted to discussion. The various Session Chairmen have summarized the essential points brought out in these discussion periods which were generally quite spirited. The authors and the publisher have made a special effort to rapidly publish an up-to-date status concerning the various aspects of trapped radiation. Almost all authors turned in their manuscripts prior to the end of the Institute and all prior to September 30, 1965. It was clearly recognized that rapid publication was essential in this rapidly changing research area. Special thanks are due to the Host, Dr. Odd Dahl, Chr. Michelsen Institute, for making all of the arrangements in Bergen, including excellent living and working facilities. Direct financial support was provided the Institute by: North Atlantic Treaty Organization, Advanced Research Projects Agency, Air Force Cam bridge Research Laboratories, Army Research Office, Defence Atomic Support Agency, and the Office of Naval Research.
Download or read book The Life Puzzle written by A.G. Cairns-Smith and published by University of Toronto Press. This book was released on 1971-12-15 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the origin of life? Molecular biology shows us one kind, but in thinking about it we must consider those generalised aspects of living organisation that are common to all conceivable forms of life. The author believes that only a combination of general biological theory and particular chemical knowledge can solve the problems of the origin and re-creation of life. This book does not fall into either the classical Haldane or Oparin schools of thought on the origin of life, but advances a thesis of its own, which, according to Professor C.H. Waddington, is one of the most important recent intellectual developments in this field. Part I considers the role of molecular biology in formulating a view of life as it exists now. Part II turns to more general aspects of the organisation of matter. In Part III the author advances his own theories on the origin of life—theories which are both revolutionary and reactionary. As he remarks, 'If my conclusions are correct it may be difficult to find the right system, but it would be easy to make a very simple organism once we have.'
Download or read book Dynamic Laser Speckle and Applications written by Hector J. Rabal and published by CRC Press. This book was released on 2018-10-03 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speckle study constitutes a multidisciplinary area with inherent complexities. In order to conquer challenges such as the variability of samples and sensitive measurements, researchers must develop a theoretical and statistical understanding of both biological and non-biological metrology using dynamic speckle laser. Dynamic Laser Speckle and Applications discusses the main methodologies used to analyze biospeckle phenomena with a strong focus on experimentation. After establishing a theoretical background in both speckle and biospeckle, the book presents the main methodologies for statistical and image analysis. It then deals with the concept of frequency decomposition before moving on to a discussion of fuzzy methods to treat dynamic speckle data. The book dedicates two sections to applications, including agricultural approaches. Additional features include photo images of experiments and software to aid in easy start-up of dynamic speckle usage. A systematic approach to new dynamic speckle laser phenomena, this book provides the physical theory and statistical background needed to analyze images formed by laser illumination in biological and non-biological samples.

Download or read book Depth written by Michael Strevens and published by Harvard University Press. This book was released on 2011-09-30 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: What does it mean for scientists to truly understand, rather than to merely describe, how the world works? Michael Strevens proposes a novel theory of scientific explanation and understanding that overhauls and augments the familiar causal approach to explanation. What is replaced is the test for explanatorily relevant causal information: Strevens discards the usual criterion of counterfactual dependence in favor of a criterion that turns on a process of progressive abstraction away from a fully detailed, physical causal story. The augmentations include the introduction of a new, non-causal explanatory relevance relation—entanglement—and an independent theory of the role of black-boxing and functional specification in explanation. The abstraction-centered notion of difference-making leads to a rich causal treatment of many aspects of explanation that have been either ignored or handled inadequately by earlier causal approaches, including the explanation of laws and other regularities, with particular attention to the explanation of physically contingent high-level laws, idealization in explanation, and probabilistic explanation in deterministic systems, as in statistical physics, evolutionary biology, and medicine. The result is an account of explanation that has especially significant consequences for the higher-level sciences: biology, psychology, economics, and other social sciences.

Download or read book Coded Modulation Techniques for Fading Channels written by Seyed Hamidreza Jamali and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coded-Modulation Techniques for Fading Channels provides the reader with a sound background for the application of bandwidth-efficient coded-modulation techniques in fading channels. The book systematically presents recent developments in the field, which has grown rapidly in recent years, and provides a solid frame of reference for further research in this area. During the past decade there has been a proliferation of research in the area of bandwidth-efficient coded-modulation techniques. The primary advantage of these schemes over modulation schemes employing traditional error correcting codes is their ability to improve the performance of the communication system without bandwidth expansion. This property makes them a suitable choice for channels which are limited in both power and bandwidth. A typical example of such channels is a mobile satellite channel, where it is desired to accommodate a large number of users in a given bandwidth with a power which is constrained by the physical size of the satellite and by the vehicle's antenna. Coded-Modulation Techniques for Fading Channels is an excellent reference for researchers and practicing engineers, and may be used as a text for advanced courses on the subject.
Download or read book Large Deviations written by S. R. S. Varadhan and published by American Mathematical Soc.. This book was released on 2016-12-08 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of large deviations deals with rates at which probabilities of certain events decay as a natural parameter in the problem varies. This book, which is based on a graduate course on large deviations at the Courant Institute, focuses on three concrete sets of examples: (i) diffusions with small noise and the exit problem, (ii) large time behavior of Markov processes and their connection to the Feynman-Kac formula and the related large deviation behavior of the number of distinct sites visited by a random walk, and (iii) interacting particle systems, their scaling limits, and large deviations from their expected limits. For the most part the examples are worked out in detail, and in the process the subject of large deviations is developed. The book will give the reader a flavor of how large deviation theory can help in problems that are not posed directly in terms of large deviations. The reader is assumed to have some familiarity with probability, Markov processes, and interacting particle systems.

Download or read book Critical Regimes of Two Phase Flows with a Polydisperse Solid Phase written by Eugene Barsky and published by Springer Science & Business Media. This book was released on 2010-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical regimes of two-phase flows with a polydisperse solid phase form the basis of such widespread industrial processes as separation of various powdery materials and minerals dressing. It is impossible to describe such complicated flows analytically. Therefore, this study concentrates on invariants experimentally revealed and theoretically grounded for such flows. This approach can be compared with the situation in gases, where in order to determine principal parameters of their state, one does not need to measure the kinetic energy and velocity of each molecule and find its contribution to the temperature and pressure. These parameters are determined in a simple way for the system on the whole. A novel conception of two-phase flows allowing the formulation of their statistical parameters is physically substantiated. On the basis of the invariants and these parameters, a comprehensive method of estimating and predicting mass transfer in such flows is developed. It is noteworthy that the presented results are mostly phenomenological. Such an approach can be successfully extended to the separation of liquids, gases and isotopes. The book is intended for students and specialists engaged in chemical technology, mineral dressing, ceramics, microelectronics, pharmacology, power generation, thermal engineering and other fields in which flows carrying solid particles are used in the technological process.
