Download or read book A Guide to Close Binary Systems written by Edwin Budding and published by CRC Press. This book was released on 2022-05-12 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Close Binary Systems provides a comprehensive survey and guide to the fast-moving field of multiple, specifically binary, stars, with an up to date account of research around 'close', i.e. interacting pairs. Such interactions allow direct quantification of stellar properties, opening up factual insights into basic building blocks of the Universe. The book provides a much needed update for the seminal Close Binary Systems of Zdenĕk Kopal. Following a comparable plan, it presents relevant subject matter with an emphasis on building a framework of understanding to serve as a supporting resource for students and researchers. The text starts from a general historical background and progresses into the main theoretical ideas supporting our prima facie interpretation of observations. The central chapters explore further into these observational methods, arranged according to the classic subdivisions of astrometry, spectroscopy and photometry. Optimal inversion of observational data into model parametrization is a theme through these chapters. Significant here is the problem of how non-uniqueness in modelling affects interpretation. The underlying issues of stellar evolution bearing on observational evidence become paramount in the last four chapters. The book proceeds step-by-step from directly understandable examples of unevolved pairs to the challenging cases where stars are found in more and more extreme conditions, leading up to the mergers of massive black hole pairs seen in the new field of gravitational wave astronomy. This is a valuable reference for postgraduate and advanced undergraduate students working in mainstream areas of stellar astrophysics, with applications also to exoplanet research which shares some methodological features. Course designers for stellar astrophysics will find a useful selection of topics within this book. Key features: • Provides a well-explained and backgrounded, up-to-date account of close binary systems, in a fast-moving field of research that is growing in scientific importance • Surveys a wide range of case-studies within the context of binary and multiple star systems • Fills an acknowledged gap in current literature Cover Image: A public memorial to Zdenek Kopal in his home town (birthplace) of Litomysl in Czechia.

Download or read book Confronting the Challenges of Participatory Culture written by Henry Jenkins and published by MIT Press. This book was released on 2009-06-05 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many teens today who use the Internet are actively involved in participatory cultures—joining online communities (Facebook, message boards, game clans), producing creative work in new forms (digital sampling, modding, fan videomaking, fan fiction), working in teams to complete tasks and develop new knowledge (as in Wikipedia), and shaping the flow of media (as in blogging or podcasting). A growing body of scholarship suggests potential benefits of these activities, including opportunities for peer-to-peer learning, development of skills useful in the modern workplace, and a more empowered conception of citizenship. Some argue that young people pick up these key skills and competencies on their own by interacting with popular culture; but the problems of unequal access, lack of media transparency, and the breakdown of traditional forms of socialization and professional training suggest a role for policy and pedagogical intervention. This report aims to shift the conversation about the "digital divide" from questions about access to technology to questions about access to opportunities for involvement in participatory culture and how to provide all young people with the chance to develop the cultural competencies and social skills needed. Fostering these skills, the authors argue, requires a systemic approach to media education; schools, afterschool programs, and parents all have distinctive roles to play. The John D. and Catherine T. MacArthur Foundation Reports on Digital Media and Learning
Download or read book Europe s 21st Century Challenge written by Didier Bigo and published by Routledge. This book was released on 2016-07-22 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the final results of the CHALLENGE research project (The Changing Landscape of European Liberty and Security) - a five-year project funded by the Sixth Framework Programme of DG Research of the European Commission. The book critically appraises the liberties of citizens and others within the EU, and the different ways in which they are affected by the proliferation of discourses, practices and norms of insecurity enacted in the name of collective and individual safety. It analyses from an interdisciplinary perspective the impacts of new techniques of surveillance and control on the liberty and security of the citizen. The book studies illiberal practices of liberal regimes in the field of security, and the relationship between the internal and external effects of these practices in an increasingly interconnected world, as well as the effects in relation to the place of the EU in world politics.
Download or read book Evolutionary Processes in Interacting Binary Stars written by Y. Kondo and published by Springer Science & Business Media. This book was released on 1992-06-30 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of IAU Symposium No. 151 `Evolutionary Processes in Interacting Binary Stars,' which was held from 5 to 9 August 1991 in Cordóba, Argentina. The primary aim of this conference was to review and evaluate our current understanding of the evolutionary processes in wide variety of interacting binary stars from their births to their deaths. Subjects included the formation of binaries, mass flow and transfer, accretion processes, and binaries with collapsed components, such as novae, X-ray binaries and binary pulsars. As the field covered is both broad and diverse, there were in all thirty-seven invited talks; sixty-two contributed papers were also presented. In addition, these proceedings contain comments from a panel discussion of the major unsolved problems of interacting binary stars.

This book was released on 2008-12-18 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stellar models are the very basic building blocks with which we build up our knowledge of the Universe. New numerical experiments are heralding a new level of sophistication in our ability to model, and understand, how stars work. This volume provides an overview and the most recent advances in modeling of stellar structure and evolution. Modeling of stars relies on our understanding of the detailed physical processes happening in stars, and the most recent observations of stars made by modern large telescopes and current high technologies. IAU Symposium 252 presents the most recent developments in five key areas, including: improvements of the physical ingredients of stellar models; the evolution of low and intermediate mass stars; the evolution of massive stars; close binary evolution; and stellar physics in the era of very large telescopes. This overview of stellar research is at a level suitable for research astronomers and graduate students.
Download or read book Active Close Binaries written by Cafer Ibanogammalu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 898 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1970s symposia or colloquia devoted to recent research on close binaries have been held around the world almost annually. At meetings of the General Assembly of the International Astronomical Union this topic has also been discussed in detail at presentations in various commission meetings and also as invited talks by leading astronomers in the field. In recent years, fundamental changes have taken place in the study of close binaries due to the improvements in observational techniques, extension of observations from X-ray to radio regions of the electromagnetic spectrum, and advances in theoretical studies. For more than a decade, a group of astronomers at Ege University Observatory has been concentrating on active close binaries with particular emphasis on the behaviour of the light curves of chromospherically active systems. Thus, we decided to organize an international meeting in Western Anatolia, where this part of Turkey had been the cradle for great developments in science during antiquity. KUljadasi, located only minutes away from Ephesus, one of the seven wonders of the world, was selected to be the meeting site. Close binary systems constitute a very rich source of information about the physical properties of the component stars. Some systems are eclipsing variables, where periodic recurrences of eclipses are observed as comparatively brief decreases in the total brightness of the binary system. Precise methods of photometric observations make it possible to obtain the light variations of these systems because of eclipses and other phenomena.
Download or read book Dynamics of Close Binary Systems written by Zdenek Kopal and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the present book will be to provide a comprehensive account of our present knowledge of the theory of dynamical phenomena exhibited by elose binary systems; and on the basis of such phenomena as have been attested by available observations to outline probable evolutionary trends of such systems in the course of time. The evolution of the stars - motivated by nuelear as weIl as gravitation al energy sources - constitutes nowadays a well-established branch of stellar astronomy. No theo ries of such an evolution are as yet sufficently specific - let alone infallible - not to require continual tests by a confrontation of their consequences with the observed prop erties of actual stars at different stages of their evolution. The discriminating power of such tests depends, of course, on the range of information offered by the test objects. Single stars which move alone in space are now known to represent only a minority of objects constituting our Galaxy (cf. Chapter 1-2); and are, moreover, not very revealing of their basic physical characteristics - such as their masses or absolute dimensions. If there were no binary systems in the sky, the only star whose vital statistics would be fully known to us would be our Sun.
Download or read book Asia and Europe in the 21st Century written by Rahul Mishra and published by Routledge. This book was released on 2021-05-25 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: How are the rising mutual concerns of Asian and European countries shaping their approaches to the international order? Contributors to this volume discuss emerging critical issues in International relations, including the Indo-Pacific constructs, China’s Belt and Road Initiative (BRI), and the progress of established regional security mechanisms like the Shanghai Cooperation Organisation. They also compare western and non-western approaches to these issues, with a holistic perspective on the origins and evolutions of these approaches. Both the Indo-Pacific constructs and BRI present a remarkable set of opportunities for Europe as well as Asia. This book presents key implications of the changing politico-security dynamics in the two regions from the perspectives of both Asian and European scholars and theoretical traditions. A must-read for scholars of International Relations with a focus on relations between Asia and Europe.
Download or read book A Kind of Mirraculas Paradise written by Sandy Allen and published by Simon and Schuster. This book was released on 2018-01-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Compelling…A bracing work of art and a loving tribute” (Los Angeles Times), this propulsive, stunning book illuminates the experience of living with schizophrenia like never before. Sandra Allen did not know their uncle Bob very well. As a child, Sandy had been told Bob was “crazy,” that he had spent time in mental hospitals while growing up in Berkeley in the 60s and 70s. But Bob had lived a hermetic life in a remote part of California for longer than Sandy had been alive, and what little Sandy knew of him came from rare family reunions or odd, infrequent phone calls. Then in 2009 Bob mailed Sandy his autobiography. Typewritten in all caps, a stream of error-riddled sentences more than sixty, single-spaced pages, the often-incomprehensible manuscript proclaimed to be a “true story” about being “labeled a psychotic paranoid schizophrenic,” and arrived with a plea to help him get his story out to the world. “Searing” (O, The Oprah Magazine), “enthralling” (Star-Tribune, Minneapolis), and “a marvel” (Esquire), A Kind of Mirraculas Paradise shows how Sandy translated Bob’s autobiography, artfully creating a gripping coming-of-age story while sticking faithfully to the facts as he shared them. Sandy also shares background information about their family, the culturally explosive time and place of their uncle’s formative years, and the vitally important questions surrounding schizophrenia and mental healthcare in America more broadly. The result is a heartbreaking and sometimes hilarious portrait of a young man striving for stability in his life as well as his mind, and an utterly unique lens into an experience that, to most people, remains unimaginable. “Thrilling…Gorgeous…a watershed in empathetic adaptation of ‘outsider’ autobiography” (The New Republic), A Kind of Mirraculas Paradise is a dazzlingly, daringly written book that’s poised to change conversations about schizophrenia and mental illness overall.
Download or read book Data Feminism written by Catherine D'Ignazio and published by MIT Press. This book was released on 2023-10-03 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new way of thinking about data science and data ethics that is informed by the ideas of intersectional feminism. Today, data science is a form of power. It has been used to expose injustice, improve health outcomes, and topple governments. But it has also been used to discriminate, police, and surveil. This potential for good, on the one hand, and harm, on the other, makes it essential to ask: Data science by whom? Data science for whom? Data science with whose interests in mind? The narratives around big data and data science are overwhelmingly white, male, and techno-heroic. In Data Feminism, Catherine D'Ignazio and Lauren Klein present a new way of thinking about data science and data ethics—one that is informed by intersectional feminist thought. Illustrating data feminism in action, D'Ignazio and Klein show how challenges to the male/female binary can help challenge other hierarchical (and empirically wrong) classification systems. They explain how, for example, an understanding of emotion can expand our ideas about effective data visualization, and how the concept of invisible labor can expose the significant human efforts required by our automated systems. And they show why the data never, ever “speak for themselves.” Data Feminism offers strategies for data scientists seeking to learn how feminism can help them work toward justice, and for feminists who want to focus their efforts on the growing field of data science. But Data Feminism is about much more than gender. It is about power, about who has it and who doesn't, and about how those differentials of power can be challenged and changed.
Download or read book Erasing the Binary Distinction of Developed and Underdeveloped written by Vinay Bahl and published by Taylor & Francis. This book was released on 2023-10-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book challenges the binary distinction of developed and underdeveloped in the categorization of any country while proposing to erase this binary with a yardstick of parity. Through a sample comparative historical study focusing on the question of the emergence of the large-scale steel industry (1880-1914) of four chosen countries, two considered "developed" (Imperial UK and Post-colonial Imperial USA) and two considered "underdeveloped" (Imperial Russia and Colonial India), it is shown how this yardstick of parity can be applied without the categorization of societies as either developed or underdeveloped.
