This proceedings volume is a collection of papers presented at the International Conference on SPT2004 focusing on symmetry, perturbation theory, and integrability.The book provides an updated overview of the recent developments in the various different fields of nonlinear dynamics, covering both theory and applications. Special emphasis is given to algebraic and geometric integrability, solutions to the N-body problem of the “choreography” type, geometry and symmetry of dynamical systems, integrable evolution equations, various different perturbation theories, and bifurcation analysis.The contributors to this volume include some of the leading scientists in the field, among them: I Anderson, D Bambusi, S Benenti, S Bolotin, M Fels, W Y Hsiang, V Matveev, A V Mikhailov, P J Olver, G Pucacco, G Sartori, M A Teixeira, S Terracini, F Verhulst and I Yehorchenko.

Book Description
This volume is concerned with the determination of the behaviour of perturbation theory at large orders in quantum mechanics and quantum field theory, and its application to the problem of summation of perturbation series. Perturbation series in quantum field theory and in many quantum mechanics models are only asymptotic and thus diverge for all values of the expansion parameter. Their behaviour at large orders provides information about whether they define the theory uniquely (the problem of Borel summability). It suggests methods to extract numerical information from the series when the expansion parameter is not small. The articles reprinted here deal with the explicit evaluation of large-order behaviour in many quantum mechanics and field theory models. The large-order behaviour is related to barrier penetration effects for unphysical values of the expansion parameter, which can be calculated by WKB or instanton methods. The calculation of critical exponents of &fgr;4 field theory is presented as a practical application.

Book Description
Automatie object recognition is a multidisciplinary research area using con cepts and tools from mathematics, computing, optics, psychology, pattern recognition, artificial intelligence and various other disciplines. The purpose of this research is to provide a set of coherent paradigms and algorithms for the purpose of designing systems that will ultimately emulate the functions performed by the Human Visual System (HVS). Hence, such systems should have the ability to recognise objects in two or three dimensions independently of their positions, orientations or scales in the image. The HVS is employed for tens of thousands of recognition events each day, ranging from navigation (through the recognition of landmarks or signs), right through to communication (through the recognition of characters or people themselves). Hence, the motivations behind the construction of recognition systems, which have the ability to function in the real world, is unquestionable and would serve industrial (e.g. quality control), military (e.g. automatie target recognition) and community needs (e.g. aiding the visually impaired). Scope, Content and Organisation of this Book This book provides a comprehensive, yet readable foundation to the field of object recognition from which research may be initiated or guided. It repre sents the culmination of research topics that I have either covered personally or in conjunction with my PhD students. These areas include image acqui sition, 3-D object reconstruction, object modelling, and the matching of ob jects, all of which are essential in the construction of an object recognition system.

Book Description
The United Nations in the 21st Century provides a comprehensive yet accessible introduction to the United Nations, exploring the historical, institutional, and theoretical foundations of the UN. This popular text for courses on international organizations and international relations also discusses the political complexities facing the organization today. Thoroughly revised throughout, the fifth edition focuses on major trends since 2012, including changing power dynamics, increasing threats to peace and security, and the growing challenges of climate change and sustainability. It examines the proliferating public-private partnerships involving the UN and the debates over reforming the Security Council and the Secretary-General selection process. This edition also includes new case studies on peacekeeping and the use of force in the Democratic Republic of Congo and Mali, transnational terrorism and the emergence of ISIS, the Security Council's failure to act in Syria, the Syrian and global refugee/migrant crisis, and the conclusion of the Millennium Development Goals and framing of the Sustainable Development Goals.

Book Description
Addressing researchers and graduate students in the active meeting ground of analysis, geometry, and dynamics, this book presents a study of renormalization of quadratic polynomials and a rapid introduction to techniques in complex dynamics. Its central concern is the structure of an infinitely renormalizable quadratic polynomial f(z) = z2 + c. As discovered by Feigenbaum, such a mapping exhibits a repetition of form at infinitely many scales. Drawing on universal estimates in hyperbolic geometry, this work gives an analysis of the limiting forms that can occur and develops a rigidity criterion for the polynomial f. This criterion supports general conjectures about the behavior of rational maps and the structure of the Mandelbrot set. The course of the main argument entails many facets of modern complex dynamics. Included are foundational results in geometric function theory, quasiconformal mappings, and hyperbolic geometry. Most of the tools are discussed in the setting of general polynomials and rational maps.

Book Description
Languages are constantly changing. New words are added to the English language every year, either borrowed or coined, and there is often railing against the 'decline' of the language by public figures. Some languages, such as French and Finnish, have academies to protect them against foreign imports. Yet languages are species-like constructs, which evolve naturally over time. Migration, imperialism, and globalization have blurred boundaries between many of them, producing new ones (such as creoles) and driving some to extinction. This book examines the processes by which languages change, from the macroecological perspective of competition and natural selection. In a series of chapters, Salikoko Mufwene examines such themes as: - natural selection in language - the actuation question and the invisible hand that drives evolution - multilingualism and language contact - language birth and language death - the emergence of Creoles and Pidgins - the varying impacts of colonization and globalization on language vitality This comprehensive examination of the organic evolution of language will be essential reading for graduate and senior undergraduate students, and for researchers on the social dynamics of language variation and change, language vitality and death, and even the origins of linguistic diversity.

Book Description
When we use science to describe and understand the world around us, we are in essence grasping nature through symmetry. Emphasizing the concepts, this book leads the reader coherently and comprehensively into the fertile field of symmetry and its applications. Among the most important applications considered are the fundamental forces of nature and the Universe. Written by a renowned expert, this book will convince all interested readers of the importance of symmetry in science.
