Buch. Condición: Neu. Neuware - As is well known, the term naturalism has carried a multitude of meanings. It generally designates the qualities of an artwork that are considered characteristic of a specific time period or movement, or even defines a stylistic epoch. However, even if considered systematically, meanings of naturalism diverge quite profoundly depending on the context of usage. What is true of all the various tendencies, methods and works is that they strive toward the imitation of nature or a heightened level of reality. This raises the question as to how techniques of pictorial description and varieties of illusionism produce knowledge. To what extent do instances of objectivity and claims to truth derive from the apparent withdrawal of artistic intervention ; Angesichts einer Vielzahl von 'Naturalismen' widmet sich der Band der Frage nach übergreifenden Zusammenhängen. Als durchgängiges Moment der verschiedenen Tendenzen, Arbeitsweisen und Werke kann gelten, dass künstlerische Naturnachahmung auf einen gesteigerten Realitätsgrad der Bildwerke zielt. Gefragt wird nach der Relevanz von Praktiken bildnerischer Beschreibung und nach Spielarten von Illusionismus.…

Buch. Condición: Neu. Neuware -The second edition of Non-extensive Entropy Econometrics for Low Frequency Series provides a new and robust power-law-based, non-extensive entropy econometrics approach to the economic modelling of ill-behaved inverse problems. Particular attention is paid to national account-based general equilibrium models known for their relative complexity.In theoretical terms, the approach generalizes Gibbs-Shannon-Golan entropy models, which are useful for describing ergodic phenomena. In essence, this entropy econometrics approach constitutes a junction of two distinct concepts: Jayne's maximum entropy principle and the Bayesian generalized method of moments. Rival econometric techniques are not conceptually adapted to solving complex inverse problems or are seriously limited when it comes to practical implementation. Recent literature showed that amplitude and frequency of macroeconomic fluctuations do not substantially diverge from many other extreme events, natural or human-related, once they are explained in the same time (or space) scale. Non-extensive entropy is a precious device for econometric modelling even in the case of low frequency series, since outputs evolving within the Gaussian attractor correspond to the Tsallis entropy limiting case of Tsallis q-parameter around unity. This book introduces a sub-discipline called Non-extensive Entropy Econometrics or, using a recent expression, Superstar Generalised Econometrics. It demonstrates, using national accounts-based models, that this approach facilitates solving nonlinear, complex inverse problems, previously considered intractable, such as the constant elasticity of substitution class of functions. This new proposed approach could extend the frontier of theoretical and applied econometrics. 226 pp. Englisch.…

Taschenbuch. Condición: Neu. Neuware - Die drei iranischen Religionen stehen in Wechselwirkung mit der Gesellschaft, die - geschichtlich und gegenwärtig - nicht auf das Staatsgebiet der heutigen Islamischen Republik Iran beschränkt ist. Der Zoroastrismus ist im ostiranischen Kulturraum, d.h. in zentralasiatischen Gebieten, entstanden, das Yezidentum ist immer eng mit den kurdischen Raum verknüpft gewesen und das Baha'itum stammt zwar aus dem persischen Milieu, hat sich aber bereits in den ersten Jahrzehnten seiner Existenz über den Iran Raum hinaus verbreitet. Daher behandelt das Buch in ausgewogener Weise das unterscheidend Eigene und das verbindend Gemeinsame der Religionen. Dies geschieht durch einen weitgehend parallelen Aufbau der drei Hauptkapitel, in denen die Entwicklung jeder Religion, ihre Weltbilder und rituellen Praktiken sowie Organisationsformen als gesellschaftliche Gruppe dargestellt werden. Das Schlusskapitel bettet sie in den religiösen Pluralismus und die Religionspolitik der Islamischen Republik Iran ein. Dadurch wird das Buch für Religionshistoriker und Theologen in gleicher Weise relevant wie für Islamwissenschaftler, Iranisten und Politik- bzw. Sozialwissenschaftler in Bezug auf den Nahen Osten.…

Buch. Condición: Neu. Neuware - The Trojan War is the subject of Homer's great epic poem Iliad - but there are also 'alternative stories' from antiquity: The Latin-language authors Dictys and Dares claim to offer eyewitness accounts and therefore a more authentic account of Troy than Homer. As the Greek-language Iliad was not accessible in the Middle Ages and until the early modern period, the two Latin works were also of the greatest importance for the reception of the Troy story up to the early modern period. In recent years, papyri have been found that are considered to be the Greek originals of the Latin works. The Tusculum edition, which is accompanied by a detailed introduction, offers these finds in two languages for the first time and, together with the bilingual presentation of the works of Dictys and Dares, provides new access to 'alternative histories' of Troy. ; Der Krieg um Troja ist Gegenstand von Homers großem Epos Ilias - doch gibt es aus der Antike auch 'alternative Geschichten' dazu: Die lateinischsprachigen Autoren Dictys und Dares nämlich behaupten, Augenzeugenberichte zu bieten und damit authentischer als Homer über Troja zu berichten. Da die griechischsprachige Ilias im Mittelalter und bis zur frühen Neuzeit nicht zugänglich war, haben die beiden lateinischen Werke zudem größte Bedeutung für die Rezeption des Troja-Stoffs bis in die frühe Neuzeit. In den letzten Jahren sind Papyri gefunden worden, die als griechische Vorlagen der lateinischen Werke gelten. Die mit einer ausführlichen Einleitung erschlossene Tusculum-Ausgabe bietet diese Funde erstmals zweisprachig und ermöglicht gemeinsam mit der zweisprachigen Präsentation der Werke von Dictys und Dares einen neuen Zugang zu 'alternativen Geschichten' von Troja.…

Buch. Condición: Neu. Neuware -In Band IV/18 werden fünf Notizbücher sowie fünf Exzerpthefte von Marx zur Landwirtschaft, Agrikulturchemie, Agrarverfassung und Grundrententheorie aus dem Zeitraum 1864-1868 in einem Umfang von rund 1400 Druckseiten erstmals publiziert. Marx' Studium der Bodenertragsdebatte beginnt mit einer erneuten Lektüre der Werke Justus von Liebigs und führt ihn zu einer Rezeption auch der Liebig-Kritiker, insbes. des Agrikulturphysikers Carl Fraas. Im Zentrum des Bandes stehen somit 'ökologische' Fragen nach Bodenerschöpfung, Klimawandel und den Grenzen natürlicher Ressourcen, die Marx in den Zusammenhang einer zunehmend kapitalistisch betriebenen Landwirtschaft rückt. Die Exzerpte bieten neue Quellen für die Diskussion, ob Marx durch seine vertiefte Auseinandersetzung mit den Naturwissenschaften eine Flucht vor dem 'Kapital' eingeleitet oder vielmehr seine Kritik der politischen Ökonomie um eine ökologische Perspektive erweitert hat. Außerdem bezeugen die Hefte Marx' anhaltendes Interesse an Fragen des fixen Kapitals sowie des Geld- und Kreditwesens, deren neueste Theoretiker Marx in Vorbereitung seiner Weiterarbeit am 'Kapital' exzerpiert. 1312 pp. Deutsch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Algorithms are the essence of programming. After their construction, they have to be translated to the codes of a specific programming language. There exists a maximum of ten basic algorithmic templates. This textbook aims to provide the reader with a more convenient and efficient method to create a program by translating algorithms, template by template with C++ and Java. This is the slogan of the book: You will be a professional programmer whenever you become a skilled algorithm designer. This book attempts to gradually strengthen the readers' ability to identify and analyze the mental commands which are issued and implemented in their brains for solving the problems in which mathematical computations are applied and try to design an algorithm based on their understanding and analyses. It then seeks to encourage the readers to develop their skills in algorithm-writing for computational problems and synchronously teach them to translate the algorithms into C++ and Java codes using the least necessary keywords. 410 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -While ports are traditionally considered national infrastructure sites that connect states to global markets, special economic zones and past free ports are portrayed as threats to national sovereignty. This book calls these narratives into question as it explores the history of planning Mumbai's ports and free zones during periods of global and regional transition from the British Raj, to national independence, to economic liberalization. The book opens with a study of an unsuccessful plan hatched by merchants in 1833 to make Bombay a free port to deal with an emerging British India and the advent of free trade. The book ends with how India's current special economic zones and emphasis on port expansion are part of broader goals to reposition India in transregional Asian trade, to connect Mumbai with northern India, and to enact local plans for a global city that threaten the very port that first connected Mumbai to the world. To understand the functionality of these port and zone projects beyond typical policy prescriptions, this book proposes portals of globalization as a spatial format that fosters processes of reterritorialization. 266 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The philosophy of the book, which makes it quite distinct from many existing texts on the subject, is based on treating the concepts of measure and integration starting with the most general abstract setting and then introducing and studying the Lebesgue measure and integration on the real line as an important particular case. The book consists of nine chapters and appendix, with the material flowing from the basic set classes, through measures, outer measures and the general procedure of measure extension, through measurable functions and various types of convergence of sequences of such based on the idea of measure, to the fundamentals of the abstract Lebesgue integration, the basic limit theorems, and the comparison of the Lebesgue and Riemann integrals. Also, studied are Lp spaces, the basics of normed vector spaces, and signed measures. The novel approach based on the Lebesgue measure and integration theory is applied to develop a better understanding of differentiation and extend the classical total change formula linking differentiation with integration to a substantially wider class of functions. Being designed as a text to be used in a classroom, the book constantly calls for the student's actively mastering the knowledge of the subject matter. There are problems at the end of each chapter, starting with Chapter 2 and totaling at 125. Many important statements are given as problems and frequently referred to in the main body. There are also 358 Exercises throughout the text, including Chapter 1 and the Appendix, which require of the student to prove or verify a statement or an example, fill in certain details in a proof, or provide an intermediate step or a counterexample. They are also an inherent part of the material. More difficult problems are marked with an asterisk, many problems and exercises are supplied with ``existential'' hints. The book is generous on Examples and contains numerous Remarks accompanying definitions, examples, and statements to discuss certain subtleties, raise questions on whether the converse assertions are true, whenever appropriate, or whether the conditions are essential. With plenty of examples, problems, and exercises, this well-designed text is ideal for a one-semester Master's level graduate course on real analysis with emphasis on the measure and integration theory for students majoring in mathematics, physics, computer science, and engineering. A concise but profound and detailed presentation of the basics of real analysis with emphasis on the measure and integration theory. Designed for a one-semester graduate course, with plethora of examples, problems, and exercises. Is of interest to students and instructors in mathematics, physics, computer science, and engineering. Prepares the students for more advanced courses in functional analysis and operator theory.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the global context of the Cold War, the relationship between liberation movements and Eastern European states obviously changed and transformed. Similarly, forms of (material) aid and (ideological) encouragement underwent changes over time. The articles assembled in this volume argue that the traditional Cold War geography of bi-polar competition with the United States is not sufficient to fully grasp these transformations. The question of which side of the ideological divide was more successful (or lucky) in impacting actors and societies in the global south is still relevant, yet the Cold War perspective falls short in unfolding the complex geographies of connections and the multipolarity of actions and transactions that exists until today. Acknowledging the complexities of liberation movements in globalization processes, the papers thus argue that activities need to be understood in their local context, including personal agendas and internal conflicts, rather than relying primarily on the traditional frame of Cold War competition. They point to the agency of individual activists in both 'Africa' and 'Eastern Europe' and the lessons, practices and languages that were derived from their often contradictory encounters. In Southern African Liberation Movements, authors from South Africa, Portugal, Austria and Germany ask: What role did actors in both Southern Africa and Eastern Europe play What can we learn by looking at biographies in a time of increasing racial and international conflict And which 'creative solutions' need to be found, to combine efforts of actors from various ideological camps Building on archival sources from various regions in different languages, case studies presented in the edition try to encounter the lack of a coherent state of the art. They aim at combining the sometimes scarce sources with qualitative interviews to give answers to the many open questions regarding Southern African liberation movements and their connections to the 'East'. 214 pp. Englisch. …

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with the autoregressive method for digital processing of random oscillations. The method is based on a one-to-one transformation of the numeric factors of the Yule series model to linear elastic system characteristics. This parametric approach allowed to develop a formal processing procedure from the experimental data to obtain estimates of logarithmic decrement and natural frequency of random oscillations. A straightforward mathematical description of the procedure makes it possible to optimize a discretization of oscillation realizations providing efficient estimates. The derived analytical expressions for confidence intervals of estimates enable a priori evaluation of their accuracy. Experimental validation of the method is also provided. Statistical applications for the analysis of mechanical systems arise from the fact that the loads experienced by machineries and various structures often cannot be described by deterministic vibration theory. Therefore, a sufficient description of real oscillatory processes (vibrations) calls for the use of random functions. In engineering practice, the linear vibration theory (modeling phenomena by common linear differential equations) is generally used. This theory's fundamental concepts such as natural frequency, oscillation decrement, resonance, etc. are credited for its wide use in different technical tasks. In technical applications two types of research tasks exist: direct and inverse. The former allows to determine stochastic characteristics of the system output X(t) resulting from a random process E(t) when the object model is considered known. The direct task enables to evaluate the effect of an operational environment on the designed object and to predict its operation under various loads. The inverse task is aimed at evaluating the object model on known processes E(t) and X(t), i.e. finding model (equations) factors. This task is usually met at the tests of prototypes to identify (or verify) its model experimentally. To characterize random processes a notion of 'shaping dynamic system' is commonly used. This concept allows to consider the observing process as the output of a hypothetical system with the input being stationary Gauss-distributed ('white') noise. Therefore, the process may be exhaustively described in terms of parameters of that system. In the case of random oscillations, the 'shaping system' is an elastic system described by the common differential equation of the second order: X (t)+2hX (t)+ _0^2 X(t)=E(t), where 0 = 2pi/ 0 is the natural frequency, T0 is the oscillation period, and h is a damping factor. As a result, the process X(t) can be characterized in terms of the system parameters - natural frequency and logarithmic oscillations decrement d = hT0 as well as the process variance. Evaluation of these parameters is subjected to experimental data processing based on frequency or time-domain representations of oscillations. It must be noted that a concept of these parameters evaluation did not change much during the last century. For instance, in case of the spectral density utilization, evaluation of the decrement values is linked with bandwidth measurements at the points of half-power of the observed oscillations. For a time-domain presentation, evaluation of the decrement requires measuring covariance values delayed by a time interval divisible by T0. Both estimation procedures are derived from a continuous description of research phenomena, so the accuracy of estimates is linked directly to the adequacy of discrete representation of random oscillations. This approach is similar a concept of transforming differential equations to difference ones with derivative approximation by corresponding finite differences. The resulting discrete model, being an approximation, features a methodical error which can be decreased but never eliminated. To render such a presentati 98 pp. E.…
