This long-awaited second edition of the classical textbook on Stellar Structure and Evolution by Kippenhahn and Weigert is a thoroughly revised version of the original text. Taking into account modern observational constraints as well as additional physical effects such as mass loss and diffusion, Achim Weiss and Rudolf Kippenhahn have succeeded in bringing the book up to the state-of-the-art with respect to both the presentation of stellar physics and the presentation and interpretation of current sophisticated stellar models. The well-received and proven pedagogical approach of the first edition has been retained. The book provides a comprehensive treatment of the physics of the stellar interior and the underlying fundamental processes and parameters. The models developed to explain the stability, dynamics and evolution of the stars are presented and great care is taken to detail the various stages in a star’s life. Just as the first edition, which remained a standard work for more than 20 years after its first publication, the second edition will be of lasting value not only for students but also for active researchers in astronomy and astrophysics.
This book presents a new methodological analysis of two competing research paradigms of artificial intelligence and cognitive science-the symbolic versus the connectionist paradigms. Providing an accessible introduction to the fundamentals of both paradigms, the book derives new objectives for future research that will help to integrate aspects of both areas to obtain more powerful AI techniques and to promote a deeper understanding of cognition.
This book explores integrated gate drivers with emphasis on new gallium nitride (GaN) power transistors, which offer fast switching along with minimum switching losses. It serves as a comprehensive, all-in-one source for gate driver IC design, written in handbook style with systematic guidelines. The authors cover the full range from fundamentals to implementation details including topics like power stages, various kinds of gate drivers (resonant, non-resonant, current-source, voltage-source), gate drive schemes, driver supply, gate loop, gate driver power efficiency and comparison silicon versus GaN transistors. Solutions are presented on the system and circuit level for highly integrated gate drivers. Coverage includes miniaturization by higher integration of subfunctions onto the IC (buffer capacitors), as well as more efficient switching by a multi-level approach, which also improves robustness in case of extremely fast switching transitions. The discussion also includes a concept for robust operation in the highly relevant case that the gate driver is placed in distance to the power transistor. All results are widely applicable to achieve highly compact, energy efficient, and cost-effective power electronics solutions.
The transition from war to peace is fraught with tension and the risk of a return to bloodshed. With so much at stake, it is crucial that the international community and local stakeholders make sense of the complex mosaic of challenges, to support a lasting, inclusive and prosperous peace. Recent missions, such as in Afghanistan, Somalia, or Sudan, have highlighted the fact that there can be no one-size-fits-all approach to steering countries away from violence and towards stability. This Adelphi offers a series of economic perspectives on conflict resolution, to show how the challenges of peacebuilding can be more effectively tackled. From the need to marry diplomatic peacemaking with development efforts, and activate the private sector in the service of peacebuilding aims, to the use of taxes and natural resource revenues as a financial base for sustainable peace, this book considers how economic factors can positively shape and drive peace processes. It takes an unflinching look at the complex ways in which power and order may be manifested in conflict zones, where unpalatable compromises with local warlords can often be the first step towards a more lasting settlement. A difficult balance must be struck by peacemakers and peacebuilders in assisting countries and communities in their transitions out of war, for the consequences of failure for countries and the wider world are too grave. In distilling expertise from a range of disciplines, this Adelphi seeks to inform a more economically integrated and responsive approach to helping countries leave behind their troubled pasts and take a fuller role in constructing their futures.
Kemmerling deftly intertwines the efficiency theory of taxation with the political basis of taxing the working poor. . . This commendable effort in interdisciplinary study and the comparative analysis of taxation is an essential reference for undergraduate and graduate students, as well as faculty and professionals of economics, political science, and taxation systems of Europe. S. Chaudhuri, Choice Taxing the Working Poor is an inspiring read for political scientists and economists interested in the relationship between taxation and employment. Based on an elegant combination of econometric analysis and historical case studies, it shows that the alleged trade-off between employment and progressive taxation has political rather than economic roots. Philipp Genschel, Jacobs University Bremen, Germany What are the economic and political forces which generate different regimes of tax on labour? What are the implications for the labour market of these different regimes? And does globalisation bring a halt to tax-based redistribution? Achim Kemmerling tackles these and other important questions in this significant book. Malcolm Sawyer, University of Leeds, UK We have been distracted from the detailed problems of financing the welfare state by the tired old twentieth-century debate between libertarian tax minimisers and maximal socialist collectivisers. We have to move on. The welfare state has to be accepted and the detailed problems of taxation to sustain it have to be addressed. This well-researched and fascinating book addresses the political and institutional origins of different tax systems and points to viable strategies of redistribution and reform. Geoffrey M. Hodgson, University of Hertfordshire, UK In most industrialized countries the tax burden of poor people has increased dramatically over the last few decades. This book analyses both the political origins of this increase and its consequences for the labour market. Achim Kemmerling illustrates that tax-based redistribution and employment are not incompatible, and that the shift away from redistribution has not occurred on grounds of economic efficiency. He goes on to show that a long-term shift from capital to labour taxation has provoked conflicts of interests between workers that have weakened the political cause of tax-based redistribution. This interdisciplinary account of the political economy of taxing low wages explains the historical and structural origins of political tensions between different types of workers and their effects on the performance of labour markets. As such, it will strongly appeal to a wide-ranging audience, including academics, students and researchers with a special interest in political science, political economy, labour markets and the economics of taxation. Practitioners in the field of labour market, social and tax policies interested in the normative consequences of taxation for the labour market will also find the book to be of great interest.
Aimed primarily at graduate students and researchers, this text is a comprehensive course in modern probability theory and its measure-theoretical foundations. It covers a wide variety of topics, many of which are not usually found in introductory textbooks. The theory is developed rigorously and in a self-contained way, with the chapters on measure theory interlaced with the probabilistic chapters in order to display the power of the abstract concepts in the world of probability theory. In addition, plenty of figures, computer simulations, biographic details of key mathematicians, and a wealth of examples support and enliven the presentation.

INTRODUCTION TO ARNOLD’S PROOF OF THE KOLMOGOROV–ARNOLD–MOSER THEOREM This book provides an accessible step-by-step account of Arnold’s classical proof of the Kolmogorov–Arnold–Moser (KAM) Theorem. It begins with a general background of the theorem, proves the famous Liouville–Arnold theorem for integrable systems and introduces Kneser’s tori in four-dimensional phase space. It then introduces and discusses the ideas and techniques used in Arnold’s proof, before the second half of the book walks the reader through a detailed account of Arnold’s proof with all the required steps. It will be a useful guide for advanced students of mathematical physics, in addition to researchers and professionals. Features • Applies concepts and theorems from real and complex analysis (e.g., Fourier series and implicit function theorem) and topology in the framework of this key theorem from mathematical physics. • Covers all aspects of Arnold’s proof, including those often left out in more general or simplifi ed presentations. • Discusses in detail the ideas used in the proof of the KAM theorem and puts them in historical context (e.g., mapping degree from algebraic topology).
In this relatively short survey, we present the core elements of the microeconomic analysis of insurance markets at a level suitable for senior undergraduate and graduate economics students. The aim of this analysis is to understand how insurance markets work, what their fundamental economic functions are, and how efficiently they may be expected to carry these out.
The movement of people in Southeast Asia is an issue of increasing importance. Countries of the Association of Southeast Asian Nations (ASEAN) are now the origin of 8 percent of the world's migrants. These countries host only 4 percent of the world's migrants but intra-regional migration has turned Malaysia, Singapore, and Thailand into regional migration hubs that are home to 6.5 million ASEAN migrants. However, significant international and domestic labor mobility costs limit the ability of workers to change firms, sectors, and geographies in ASEAN. This report takes an innovative approach to estimate the costs for workers to migrate internationally. Singapore and Malaysia have the lowest international labor mobility costs in ASEAN while workers migrating to Myanmar and Vietnam have the highest costs. Singapore and Malaysia's more developed migration systems are a key reason for their lower labor mobility costs. How easily workers can move to take advantage of new opportunities is important in determining how they fare under the increased economic integration planned for ASEAN. To study this question, the report simulates how worker welfare is affected by enhanced trade integration under different scenarios of labor mobility costs. Region-wide, worker welfare would be 14 percent higher if barriers to mobility were reduced for skilled workers, and an additional 29 percent if barriers to mobility were lowered for all workers. Weaknesses in migration systems increase international labor mobility costs, but policy reforms can help. Destination countries should work toward systems that are responsive to economic needs and consistent with domestic policies. Sending countries should balance protections for migrant workers with the needs of economic development.
This book provides a thorough background to the emerging field of medical robotics. It covers the mathematics needed to understand the use of robotic devices in medicine, including but not limited to robot kinematics, hand-eye and robot-world calibration, reconstruction, registration, motion planning, motion prediction, motion correlation, motion replication and motion learning. Additionally, basic methods behind state-of-the art robots like the DaVinci system, the CyberKnife, motorized C-arms and operating microscopes as well as stereotactic frames are presented. The book is a text book for undergraduates in computer science and engineering. The main idea of the book is to motivate the methods in robotics in medical applications rather than industrial applications. The book then follows the standard path for a robotics textbook. It is thus suitable for a first course in robotics for undergraduates. It is the first textbook on medical robotics.
Scholarship on Iraq under the Ba’th regime has traditionally focused on the rule of Saddam Hussein and his narrow inner circle. The centrality of the former president in Iraqi politics until spring 2003 and the tyranny of his regime were evident, and available sources concerning developments inside Iraqi society during that period were scarce. This book explores whether traditional paradigms of totalitarian rule can be applied to Ba’thist Iraq, closely examining state-society relations and uncovering the nature of the regime and how Iraqis lived with it. The study creates a conceptual framework for understanding the inner dynamics of a dictatorship that encompasses a variety of disciplines - comparative historiography, political science, literary and art criticism, and gender studies. Drawing on a comparative reading of the historiography of other regimes commonly perceived as totalitarian dictatorships, particularly Nazi Germany, the author looks beyond the spheres of state politics, economy and jurisdiction to also include the so called ‘soft issues’ of social norms, cultural and ideological production. By interpreting recent Iraqi history along such lines, the author demonstrates how cross-regional comparative perspectives and an interdisciplinary approach can contribute to the study of Iraq.
