A group of authors from the Arctic and Antarctic Research Institute in St Petersburg, Russia, have all achieved individual doctoral theses on various aspects of Arctic and Antarctic research. This book is written by experienced group of researchers and authors.
First published in 1970, Professor Gerschenkron's theme is the contribution which the study of Russian economic history can make to the problems which have preoccupied Western historians. He first considers the way in which the case of the old Believers in Russia, who refused to support the official church but played an important entrepreneurial role in nineteenth-century economic development, bears upon Max Weber's celebrated thesis on the relations between the Protestant ethic and the spirit of capitalism. In the course of his discussion, Professor Gerschenkron provides important information on the doctrinal beliefs of this group, their social status and the extent to which they were persecuted and discriminated against by the State. His conclusion is that the persecution certainly afforded sufficient impulse to engage in profitable activities and to develop the traits Weber considered as specific features of the 'capitalist' spirit.
Coinciding with the centennial of the Pan American Union (now the Organization of American States), González explores how nineteenth- and twentieth-century U.S. architects and their clients built a visionary Pan-America to promote commerce and cultural exchange between United States and Latin America. Late in the nineteenth century, U.S. commercial and political interests began eyeing the countries of Latin America as plantations, farms, and mines to be accessed by new shipping lines and railroads. As their desire to dominate commerce and trade in the Western Hemisphere grew, these U.S. interests promoted the concept of "Pan-Americanism" to link the United States and Latin America and called on U.S. architects to help set the stage for Pan-Americanism's development. Through international expositions, monuments, and institution building, U.S. architects translated the concept of a united Pan-American sensibility into architectural or built form. In the process, they also constructed an artificial ideological identity—a fictional Pan-America peopled with imaginary Pan-American citizens, the hemispheric loyalists who would support these projects and who were the presumed benefactors of this presumed architecture of unification. Designing Pan-America presents the first examination of the architectural expressions of Pan-Americanism. Concentrating on U.S. architects and their clients, Robert Alexander González demonstrates how they proposed designs reflecting U.S. presumptions and projections about the relationship between the United States and Latin America. This forgotten chapter of American architecture unfolds over the course of a number of international expositions, ranging from the North, Central, and South American Exposition of 1885–1886 in New Orleans to Miami's unrealized Interama fair and San Antonio's HemisFair '68 and encompassing the Pan American Union headquarters building in Washington, D.C. and the creation of the Columbus Memorial Lighthouse in the Dominican Republic.
Schumann resonance has been studied for more than half a century. The field became popular among researchers of the terrestrial environment using natural sources of electromagnetic radiation—lightning strokes, primarily—and now many Schumann observatories have been established around the world. A huge number of publications can be found in the literature, the most recent collection of which was presented in a special Schumann resonance section of the journal Radio Science in 2007. The massive publications, however, impede finding information about how to organize measurements and start observations of global electromagnetic resonance. Relevant information is scattered throughout many publications, which are not always available. The goal of this book is to collect all necessary data in a single edition in order to describe the demands of the necessary equipment and the field-site as well as the impact of industrial and natural interference, and to demonstrate typical results and obstacles often met in measurements. The authors not only provide representative results but also describe unusual radio signals in the extremely low-frequency (ELF) band and discuss signals in the adjacent frequency ranges.
The principal focus of this book is the physical processes in the World Ocean which regulate the interannual-to-multidecadal natural variability of the climate system, and some key atmospheric and marine manifestations of this variability. It analyses a number of Atlantic and Indo-Pacific signals, and describes their regional atmospheric and marine manifestations. The role of the Ocean in the recent hiatus of global warming and the probability of abrupt climate change due to thermohaline catastrophe are also assessed. The book pays special attention to the change of parameters of synoptic atmospheric disturbances over the Northern Hemisphere and its sub-regions in different phases of the natural quasi-periodical climatic signals. It will appeal to oceanographers, climatologists, meteorologists, hydrologist, geographers and the general reader interested in the problem of climate change all over the globe, especially with regards to Eastern Europe and the Black Sea region.
This monograph offers a wide array of contemporary information on weather radar polarimetry and its applications. The book tightly connects the microphysical processes responsible for the development and evolution of the clouds’ bulk physical properties to the polarimetric variables, and contains the procedures on how to simulate realistic polarimetric variables. With up-to-date polarimetric methodologies and applications, the book will appeal to practicing radar meteorologists, hydrologists, microphysicists, and modelers who are interested in the bulk properties of hydrometeors and quantification of these with the goals to improve precipitation measurements, understanding of precipitation processes, or model forecasts.

Alexander Brodsky and Ilya Utkin are the best known of a loosely organized group of Soviet artists known as "Paper Architects," who designed much but built little in the early days of Glasnost, in the late 1980s. Many of their elaborate etchings, in which they depicted outlandish, often impossible, structures and cityscapes of allegorical content, were collected in our 1990 book Brodsky & Utkin. Now, with the addition of forty-three new and never-before-published prints, we are pleased to announce this updated edition. In their designs, by turns funny, cerebral, and deeply human, Brodsky & Utkin borrow from Egyptian tombs, Ledoux's visionary architecture, Le Corbusier's urban master palns, and other historical precedents, collaging these heterogeneous forms in learned and layered scrambles. Underlying the wit and visual inventiveness is an unmistakable moral: that the dehumanizing architecture of the sort seen in Russian cities in the 1980s and 1990s, and elsewhere around the globe, takes a sinister toll. A new preface assesses the works of Brodsky & Utkin and reminds us that the greatest art is often born of adversity. Beautifully printed in 300-screen dry-trap duotones by the Steinhauer Press, Brodsky & Utkin is a book for artists, architects, and collectors alike.
This book investigates architecture as a form of diplomacy in the context of the Second World War at six major European international and national expositions that took place between 1937 and 1959. The volume gives a fascinating account of architecture assuming the role of the carrier of war-related messages, some of them camouflaged while others quite frank. The famous standoffs between the Stalinist Russia and the Nazi Germany in Paris 1937, or the juxtaposition of the USSR and USA pavilions in Brussels 1958, are examples of very explicit shows of force. The book also discusses some less known - and more subtle - messages, revealed through an examination of several additional pavilions in both Paris and Brussels; of a series of expositions in Moscow; of the Universal Exhibition in Rome that was planned to open in 1942; and of London’s South Bank Exposition of 1951: all of them related, in one way or another, to either an anticipation of the global war or to its horrific aftermaths. A brief discussion of three pre-World War II American expositions that are reviewed in the Epilogue supports this point. It indicates a significant difference in the attitude of American exposition commissioners, who were less attuned to the looming war than their European counterparts. The book provides a novel assessment of modern architecture’s involvement with national representation. Whether in the service of Fascist Italy or of Imperial Japan, of Republican Spain or of the post-war Franquista regime, of the French Popular Front or of socialist Yugoslavia, of the arising FRG or of capitalist USA, of Stalinist Russia or of post-colonial Britain, exposition architecture during the period in question was driven by a deep faith in its ability to represent ideology. The book argues that this widespread confidence in architecture’s ability to act as a propaganda tool was one of the reasons why Modernist architecture lent itself to the service of such different masters.
Award-winning monograph of the Ferran Sunyer i Balaguer Prize 2001. Subgroup growth studies the distribution of subgroups of finite index in a group as a function of the index. In the last two decades this topic has developed into one of the most active areas of research in infinite group theory; this book is a systematic and comprehensive account of the substantial theory which has emerged. As well as determining the range of possible 'growth types', for finitely generated groups in general and for groups in particular classes such as linear groups, a main focus of the book is on the tight connection between the subgroup growth of a group and its algebraic structure. A wide range of mathematical disciplines play a significant role in this work: as well as various aspects of infinite group theory, these include finite simple groups and permutation groups, profinite groups, arithmetic groups and Strong Approximation, algebraic and analytic number theory, probability, and p-adic model theory. Relevant aspects of such topics are explained in self-contained 'windows'.
This book is an introduction to financial mathematics. It is intended for graduate students in mathematics and for researchers working in academia and industry. The focus on stochastic models in discrete time has two immediate benefits. First, the probabilistic machinery is simpler, and one can discuss right away some of the key problems in the theory of pricing and hedging of financial derivatives. Second, the paradigm of a complete financial market, where all derivatives admit a perfect hedge, becomes the exception rather than the rule. Thus, the need to confront the intrinsic risks arising from market incomleteness appears at a very early stage. The first part of the book contains a study of a simple one-period model, which also serves as a building block for later developments. Topics include the characterization of arbitrage-free markets, preferences on asset profiles, an introduction to equilibrium analysis, and monetary measures of financial risk. In the second part, the idea of dynamic hedging of contingent claims is developed in a multiperiod framework. Topics include martingale measures, pricing formulas for derivatives, American options, superhedging, and hedging strategies with minimal shortfall risk. This fourth, newly revised edition contains more than one hundred exercises. It also includes material on risk measures and the related issue of model uncertainty, in particular a chapter on dynamic risk measures and sections on robust utility maximization and on efficient hedging with convex risk measures. Contents: Part I: Mathematical finance in one period Arbitrage theory Preferences Optimality and equilibrium Monetary measures of risk Part II: Dynamic hedging Dynamic arbitrage theory American contingent claims Superhedging Efficient hedging Hedging under constraints Minimizing the hedging error Dynamic risk measures
The book focuses on the next fields of computer science: combinatorial optimization, scheduling theory, decision theory, and computer-aided production management systems. It also offers a quick introduction into the theory of PSC-algorithms, which are a new class of efficient methods for intractable problems of combinatorial optimization. A PSC-algorithm is an algorithm which includes: sufficient conditions of a feasible solution optimality for which their checking can be implemented only at the stage of a feasible solution construction, and this construction is carried out by a polynomial algorithm (the first polynomial component of the PSC-algorithm); an approximation algorithm with polynomial complexity (the second polynomial component of the PSC-algorithm); also, for NP-hard combinatorial optimization problems, an exact subalgorithm if sufficient conditions were found, fulfilment of which during the algorithm execution turns it into a polynomial complexity algorithm. Practitioners and software developers will find the book useful for implementing advanced methods of production organization in the fields of planning (including operative planning) and decision making. Scientists, graduate and master students, or system engineers who are interested in problems of combinatorial optimization, decision making with poorly formalized overall goals, or a multiple regression construction will benefit from this book.
A superbly illustrated narrative of how Napoleon skilfully extracted his Grande Armee from the clutches of the pursuing Russian armies. Much has been written about the Battle of the Berezina and the 1812 Russian campaign in general, during which the cold winter devastated the Grande Armée. Historians often praise Napoleon for his actions at the Berezina and attribute his success to a brilliant strategic mind, laying a trap that deceived the Russians and resulted in a remarkable feat in the history of warfare. Drawing on contemporary sources (letters, diaries, memoirs), and featuring an extensive order of battle, this book recreates in hourly detail one of the great escapes in military history, a story often told with embellishments that require a more critical examination. Although the core of Napoleon's army escaped, tens of thousands were killed in the battle, trampled in the rush for the bridge, drowned in the icy waters of the Berezina, or captured. Written by an acknowledged expert on the period, and using a broad range of sources from all sides, this title brings to life in stunning visual detail, using maps, battlescene artworks and period illustrations, the events of late November 1812, as Napoleon's retreating, desperate Grand Armée extricated itself from the clutches of the Russian armies under Kutuzov, Wittgenstein and Chichagov in an epic feat of heroism and masterful tactics.
This book is about the early era of the Russian space challenge. It is based on the notes of Vladimir Suvorov, a distinguished chief documentary cinematographer, who eyewitnessed and described in his top secret diary all these events from 1959 to 1969. He and his team made 35 films on the Russian conquest of space. He worked closely with the key scientists including Chief Designer Sergey Korolev, the President of the Academy of Sciences Mstislav Keldish and other high ranking military officers who were in charge of the Soviet space program. Many cosmonauts, especially the first ones like Yuri Gagarin, German Titov, et al., became his friends. This book is the first close up and personal account of these remarkable events.
Aimed at engineering students and professionals working in the field of mechanics of space flight, this book examines space tether systems – one of the most forward-thinking directions of modern astronautics. The main advantage of this technology is the simplicity, profitability and ecological compatibility: space tethers allow the execution of various manoeuvers in orbit without costs of jet fuel due to the use of gravitational and electromagnetic fields of the Earth. This book will acquaint the reader with the modern state of the space tether's dynamics, with specific attention on the research projects of the nearest decades. This book presents the most effective mathematical models and the methods used for the analysis and prediction of space tether systems' motion; attention is also given to the influence of the tether on spacecraft's motion, to emergencies and chaotic modes. - Written by highly qualified experts with practical experience in both the fields of mechanics of space flight, and in the teaching - Contains detailed descriptions of mathematical models and methods, and their features, that allow the application of the material of the book to the decision of concrete practical tasks - New approaches to the decision of problems of space flight mechanics are offered, and new problems are posed
This anthology, consisting of two volumes, is intended to equip background researchers, practitioners and students of international mathematics education with intimate knowledge of mathematics education in Russia. Volume I, entitled Russian Mathematics Education: History and World Significance, consists of several chapters written by distinguished authorities from Russia, the United States and other nations. It examines the history of mathematics education in Russia and its relevance to mathematics education throughout the world. The second volume, entitled Russian Mathematics Education: Programs and Practices will examine specific Russian programs in mathematics, their impact and methodological innovations. Although Russian mathematics education is highly respected for its achievements and was once very influential internationally, it has never been explored in depth. This publication does just that.
Singular integral operators play a central role in modern harmonic analysis. Simplest examples of singular kernels are given by Calderon-Zygmund kernels. Many important properties of singular integrals have been thoroughly studied for Calderon-Zygmund operators. In the 1980's and early 1990's, Coifman, Weiss, and Christ noticed that the theory of Calderon-Zygmund operators can be generalized from Euclidean spaces to spaces of homogeneous type. The purpose of this book is to make the reader believe that homogeneity (previously considered as a cornerstone of the theory) is not needed. This claim is illustrated by presenting two harmonic analysis problems famous for their difficulty. The first problem treats semiadditivity of analytic and Lipschitz harmonic capacities. The volume presents the first self-contained and unified proof of the semiadditivity of these capacities. The book details Tolsa's solution of Painleve's and Vitushkin's problems and explains why these are problems of the theory of Calderon-Zygmund operators on nonhomogeneous spaces. The exposition is not dimension-specific, which allows the author to treat Lipschitz harmonic capacity and analytic capacity at the same time. The second problem considered in the volume is a two-weight estimate for the Hilbert transform. This problem recently found important applications in operator theory, where it is intimately related to spectral theory of small perturbations of unitary operators. The book presents a technique that can be helpful in overcoming rather bad degeneracies (i.e., exponential growth or decay) of underlying measure (volume) on the space where the singular integral operator is considered. These situations occur, for example, in boundary value problems for elliptic PDE's in domains with extremely singular boundaries. Another example involves harmonic analysis on the boundaries of pseudoconvex domains that goes beyond the scope of Carnot-Caratheodory spaces. The book is suitable for graduate students and research mathematicians interested in harmonic analysis.
This book introduces the phenomenology and theory of hadron form factors in a consistent manner, deriving step-by-step the key equations, defining the form factors from the matrix elements of hadronic transitions and deriving their symmetry relations. Explained are several general concepts of particle theory and phenomenology exemplified by hadron form factors. The main emphasis here is on learning the analytical methods in particle phenomenology. Many examples of hadronic processes involving form factors are considered, from the pion electromagnetic scattering to heavy B-meson decays. In the second part of the book, modern techniques of the form factor calculation, based on the method of sum rules in the theory of strong interactions, quantum chromodynamics, are introduced in an accessible manner. This book will be a useful guide for graduate students and early-career researchers working in the field of particle phenomenology and experiments. Features: • The first book to address the phenomenology of hadron form factors at a pedagogical level in one coherent volume • Contains up-to-date descriptions of the most important form factors of the electroweak transitions investigated in particle physics experiments

From New York Times bestselling author Tasha Alexander comes the latest installment in the Lady Emily series. Death in St. Petersburg is a gripping new tale that will mesmerize fans of historical fiction and classic mysteries alike. After the final curtain of Swan Lake, an animated crowd exits the Mariinsky theatre brimming with excitement from the night’s performance. But outside the scene is somber. A ballerina’s body lies face down in the snow, blood splattered like rose petals over the costume of the Swan Queen. The crowd is silenced by a single cry— “Nemetseva is dead!” Amongst the theatergoers is Lady Emily, accompanying her dashing husband Colin in Russia on assignment from the Crown. But it soon becomes clear that Colin isn’t the only one with work to do. When the dead ballerina’s aristocratic lover comes begging for justice, Emily must apply her own set of skills to discover the rising star’s murderer. Her investigation takes her on a dance across the stage of Tsarist Russia, from the opulence of the Winter Palace, to the modest flats of ex-ballerinas and the locked attics of political radicals. A mysterious dancer in white follows closely behind, making waves through St. Petersburg with her surprise performances and trail of red scarves. Is it the sweet Katenka, Nemetseva’s childhood friend and favorite rival? The ghost of the murdered étoile herself? Or, something even more sinister?
Situated in the breathtaking Caucasus Mountains between the Black and the Caspian Seas, the country of Georgia sits at the crossroads between Europe and Asia; it has gone through more turbulence and change in the last twenty five years—the casting off of the Soviet regime, a civil war, two ethno-territorial conflicts, economic collapse, corruption, government inefficiency, and massive emigration—than most countries go through in 250 years. This small nation's strategic location at the crossroads of different civilizations has been a curse as well as a blessing. Once a battlefield between the ancient empires and the Christian and Islamic worlds, today it is caught between its NATO aspirations and its location in Russia’s backyard. Yet, despite all challenges and hardships, this resilient and ancient country, with thousands of years of winemaking, three-thousand years of statehood, and almost two millennia of Christianity, continues to survive and thrive. This book uses its chronology; glossary; introduction; appendixes; maps; bibliography; and over 900 hundred cross-referenced dictionary entries on important persons, places, events and institutions, as well as significant political, economic, social, and cultural aspects to trace Georgia's history and predict its future. This historical dictionary is an excellent access point for students, researchers, and anyone wanting to know more about Georgia.

This monograph evolved over a period of nine years from a series of papers and presentations addressing the subject of passive vibration control of mechanical s- tems subjected to broadband, transient inputs. The unifying theme is Targeted - ergy Transfer – TET, which represents a new and unique approach to the passive control problem, in which a strongly nonlinear, fully passive, local attachment, the Nonlinear Energy Sink – NES, is employed to drastically alter the dynamics of the primary system to which it is attached. The intrinsic capacity of the properly - signed NES to promote rapid localization of externally applied (narrowband) - bration or (broadband) shock energy to itself, where it can be captured and dis- pated, provides a powerful strategy for vibration control and the opens the pos- bility for a wide range of applications of TET, such as, vibration and shock i- lation, passive energy harvesting, aeroelastic instability (?utter) suppression, se- mic mitigation, vortex shedding control, enhanced reliability designs (for ex- ple in power grids) and others. The monograph is intended to provide a thorough explanation of the analytical, computational and experimental methods needed to formulate and study TET in mechanical and structural systems. Several prac- cal engineering applications are examined in detail, and experimental veri?cation and validation of the theoretical predictions are provided as well. The authors also suggest a number of possible future applications where application of TET seems promising. The authors are indebted to a number of sponsoring agencies.
This book analyzes various properties and structures of ice from the point of view to solve problems in civil aviation. The Arctic zone of the Russian Federation, together with large territories of Siberia and the Far East, is a zone, that is insufficiently provided with ground navigation facilities, as well as platforms and airfields for landing aircraft, including in the event of unpredictable situations. However, most of this area, especially in winter, is covered with ice, which can be used to solve this problem. The possibility of using ice sheets for the construction of airfields or the location of ground-based flight support facilities requires careful study and analysis. This book is devoted to the study of the properties and structure of ice, with a view for use in civil aviation to construct ice airfields and the placement of ground-based flight support facilities.
Most histories of Soviet cinema portray the 1970s as a period of stagnation with the gradual decline of the film industry. This book, however, examines Soviet film and television of the era as mature industries articulating diverse cultural values via new genre models. During the 1970s, Soviet cinema and television developed a parallel system of genres where television texts celebrated conservative consensus while films manifested symptoms of ideological and social crises. The book examines the genres of state-sponsored epic films, police procedural, comedy and melodrama, and outlines how television gradually emerged as the major form of Russo-Soviet popular culture. Through close analysis of well-known film classics of the period as well as less familiar films and television series, this groundbreaking work helps to deconstruct the myth of this era as a time of cultural and economic stagnation and also helps us to understand the persistence of this myth in the collective memory of Putin-era Russia. This monograph is the first book-length English-language study of film and television genres of the late Soviet era.
This second edition is a corrected and extended version of the first. It is a textbook for students, as well as a reference book for the working mathematician, on cohomological topics in number theory. In all it is a virtually complete treatment of a vast array of central topics in algebraic number theory. New material is introduced here on duality theorems for unramified and tamely ramified extensions as well as a careful analysis of 2-extensions of real number fields.
Discover the latest advances in ferroelectric and piezoelectric material sciences with this comprehensive monograph, divided into six chapters, each offering unique insights into the field.Chapter 1 delves into the manufacture and study of new ceramic materials, focusing on complex oxides of various metals (Aurivillius phases). The authors explore layered bismuth titanates and niobates, known for their high Curie temperature, and discuss how varying their chemical composition can lead to significant changes in their electrophysical properties. Chapter 2 explores the fascinating world of ferroelectrics — dielectrics with spontaneous polarization. Mathematical models and approaches of fractional calculus are used to understand the process of polarization switching in these materials, shedding light on the fractality of electrical responses. In Chapter 3, readers gain valuable insights into the inhomogeneous polarization process of polycrystalline ferroelectrics, a crucial stage in creating piezoceramic samples for energy converters. The authors present a comprehensive mathematical model that allows the determination of various characteristics, including dielectric and piezoelectric hysteresis loops and the effect of attenuation processes.Chapter 4 focuses on state-of-the-art piezoelectric energy harvesting, discussing theoretical, experimental, and computer modelling approaches. The authors discuss piezoelectric generators (PEGs) of different types (cantilever, stack and axis) and nonlinear effects arising at their operation. Chapter 5 presents expanded test and finite element models for cantilever-type and axial-type PEGs with active elements. The studies cover various structural and electric schemes of the PEGs with proof mass, bimorph and cylindrical piezoelectric elements, and excitation loads. Finally, Chapter 6 reviews some results in the last five years, obtained in modelling the vibration of devices from piezoactive materials, including five important effects: piezoelectric, flexoelectric, pyroelectric, piezomagnetic and flexomagnetic.As a diverse addition to the literature, this book is a relevant resource for researchers, engineers, and students seeking to expand their knowledge of cutting-edge developments in this exciting field.
The full story of Napoleon’s legendary escape from Russia under seemingly impossible odds is recounted in this thrillingly vivid military history. In the winter of 1812, Napoleon's army retreated from Moscow under appalling conditions, hunted by three separate Russian armies. By late November, Napoleon had reached the banks of the River Berezina—the last natural obstacle between his army and the safety of the Polish frontier. But instead of finding the river frozen solid enough to march his men across, an unseasonable thaw had turned the Berezina into an icy torrent. Having already ordered the burning of his bridging equipment, Napoleon's predicament was serious enough: but with the army of Admiral Chichagov holding the opposite bank, and those of Kutusov and Wittgenstein closing fast, it was critical. In a gripping narrative that draws on contemporary sources—including letters, diaries and memoirs—Alexander Mikaberidze describes how Napoleon rose from the pit of despair to execute one of the greatest escapes in military history.
In 1908, Maria and her husband, music critic and writer Pierre d'Alheim, established the House of Song (Dom pesni in Russia, La Maison du Lied in France). Through her performances, his lectures, their publishing activities and by hosting international competitions, the House of Song influenced the musical climate of Europe.".
The telegraph process is a useful mathematical model for describing the stochastic motion of a particle that moves with finite speed on the real line and alternates between two possible directions of motion at random time instants. That is why it can be considered as the finite-velocity counterpart of the classical Einstein-Smoluchowski's model of the Brownian motion in which the infinite speed of motion and the infinite intensity of the alternating directions are assumed. The book will be interesting to specialists in the area of diffusion processes with finite speed of propagation and in financial modelling. It will also be useful for students and postgraduates who are taking their first steps in these intriguing and attractive fields.
This book gives an exposition of the exciting field of control of oscillatory and chaotic systems, which has numerous potential applications in mechanics, laser and chemical technologies, communications, biology and medicine, economics, ecology, etc.A novelty of the book is its systematic application of modern nonlinear and adaptive control theory to the new class of problems. The proposed control design methods are based on the concepts of Lyapunov functions, Poincare maps, speed-gradient and gradient algorithms. The conditions which ensure such control goals as an excitation or suppression of oscillations, synchronization and transformation from chaotic mode to the periodic one or vice versa, are established. The performance and robustness of control systems under disturbances and uncertainties are evaluated.The described methods and algorithms are illustrated by a number of examples, including classical models of oscillatory and chaotic systems: coupled pendula, brusselator, Lorenz, Van der Pol, Duffing, Henon and Chua systems. Practical examples from different fields of science and technology such as communications, growth of thin films, synchronization of chaotic generators based on tunnel diods, stabilization of swings in power systems, increasing predictability of business-cycles are also presented.The book includes many results on nonlinear and adaptive control published previously in Russian and therefore were not known to the West.Researchers, teachers and graduate students in the fields of electrical and mechanical engineering, physics, chemistry, biology, economics will find this book most useful. Applied mathematicians and control engineers from various fields of technology dealing with complex oscillatory systems will also benefit from it.
Themes of identity, faith, and redemption combine as a disillusioned KGB assassin and an insecure female U.S. diplomat track down an Ivy League professor running a prostitution ring in Ukraine. Anatoly Filatov is the "whiskey priest," a despairing Communist true believer, whose world comes crashing down with the collapse of the USSR. Jane Sweet is the foreign-service officer, a Ukrainian-American woman who discovers her identity, as both a woman and a Ukrainian, while liberating herself from her past. The action heats up as Filatov, who is a part-time hit man for the Russian Mafia, kills three American professors in Vienna. The fourth, a cynical Ivy League professor and Soviet émigré, Igor Bazarov, escapes to Kiev. The four professors stole millions of dollars from the Mafia and invested in a prostitution ring that exploits Ukrainian women. Filatov and Sweet pursue Bazarov throughout Ukraine, and, along the way, Filatov seduces Sweet. As the two close in on Bazarov, Sweet realizes she has been used--and plots revenge in a stunning conclusion.
This landmark book deals with nonlinear normal modes (NNMs) and nonlinear mode localization. Offers an analysis which enables the study of various nonlinear phenomena having no counterpart in linear theory. On a more theoretical level, the concept of NNMs will be shown to provide an excellent framework for understanding a variety of distinctively nonlinear phenomena such as mode bifurcations and standing or traveling solitary waves.
It is a great satisfaction for a mathematician to witness the growth and expansion of a theory in which he has taken some part during its early years. When H. Weyl coined the words "classical groups", foremost in his mind were their connections with invariant theory, which his famous book helped to revive. Although his approach in that book was deliberately algebraic, his interest in these groups directly derived from his pioneering study of the special case in which the scalars are real or complex numbers, where for the first time he injected Topology into Lie theory. But ever since the definition of Lie groups, the analogy between simple classical groups over finite fields and simple classical groups over IR or C had been observed, even if the concept of "simplicity" was not quite the same in both cases. With the discovery of the exceptional simple complex Lie algebras by Killing and E. Cartan, it was natural to look for corresponding groups over finite fields, and already around 1900 this was done by Dickson for the exceptional Lie algebras G and E • However, a deep reason for this 2 6 parallelism was missing, and it is only Chevalley who, in 1955 and 1961, discovered that to each complex simple Lie algebra corresponds, by a uniform process, a group scheme (fj over the ring Z of integers, from which, for any field K, could be derived a group (fj(K).
The authors, leading representatives of Russian space research and industry, show the results and future prospects of astronautics at the start of the third millennium. The focus is on the development of astronautics in Russia in the new historical and economic conditions. The text spotlights the basic trends in space related issues before moving on to describe the possibilities of the wide use of space technologies and its numerous applications such as navigation and communication, space manufacturing, and space biotechnology. The book contains a large amount of facts described in a way understandable without specialist knowledge. The text is accompanied by many photographs, charts and diagrams, mostly in color.
The book is devoted to the foundations of the theory of boundary-value problems for various classes of systems of differential-operator equations whose linear part is represented by Fredholm operators of the general form. A common point of view on numerous classes of problems that were traditionally studied independently of each other enables us to study, in a natural way, the theory of these problems, to supplement and improve the existing results, and in certain cases, study some of these problems for the first time. With the help of the technique of generalized inverse operators, the Vishik– Lyusternik method, and iterative methods, we perform a detailed investigation of the problems of existence, bifurcations, and branching of the solutions of linear and nonlinear boundary-value problems for various classes of differential-operator systems and propose new procedures for their construction. For more than 11 years that have passed since the appearance of the first edition of the monograph, numerous new publications of the authors in this direction have appeared. In this connection, it became necessary to make some additions and corrections to the previous extensively cited edition, which is still of signifi cant interest for the researchers. For researchers, teachers, post-graduate students, and students of physical and mathematical departments of universities.

The mathematical description of complex spatiotemporal behaviour observed in dissipative continuous systems is a major challenge for modern research in applied mathematics. While the behaviour of low-dimensional systems, governed by the dynamics of a finite number of modes is well understood, systems with large or unbounded spatial domains show intrinsic infinite-dimensional behaviour --not a priori accessible to the methods of finite dimensionaldynamical systems. The purpose of the four contributions in this book is to present some recent and active lines of research in evolution equations posed in large or unbounded domains. One of the most prominent features of these systems is the propagation of various types of patterns in the form of waves, such as travelling and standing waves and pulses and fronts. Different approaches to studying these kinds of phenomena are discussed in the book. A major theme is the reduction of an original evolution equation in the form of a partial differential equation system to a simpler system of equations, either a system of ordinary differential equation or a canonical system of PDEs. The study of the reduced equations provides insight into the bifurcations from simple to more complicated solutions and their stabilities. .
The term 'Brutalism' is used to describe a form of architecture that appeared, mainly in Europe, from around 1945-75. Uncomprimisingly modern, this trend in architecture was both striking and arresting and, perhaps like no other style before or since, aroused extremes of emotion and debate. Some regarded Brutalist buildings as monstrous soulless structures of concrete, steel and glass, whereas others saw the genre as a logical progression, having its own grace and balance. In this revised second edition, Alexander Clement continues the debate of Brutalism in post-war Britain to the modern day, studying a number of key buildings and developments in the fields of civic, educational, commercial, leisure, private and ecclesiastical architecture. With new and improved illustrations, fresh case studies and profiles of the most influential architects, this new edition affords greater attention to iconic buildings and structures. Now that the age of Brutalism is a generation behind us, it is possible to view the movement with a degree of rational reappraisal, study how the style evolved and gauge its effect on Britain's urban landscape. This book will be of interest to architecture students, design students and anyone interested in post-war architecture. Fully illustrated with 160 colour and 4 black & white photographs.
