Variational calculus has been the basis of a variety of powerful methods in the ?eld of mechanics of materials for a long time. Examples range from numerical schemes like the ?nite element method to the determination of effective material properties via homogenization and multiscale approaches. In recent years, however, a broad range of novel applications of variational concepts has been developed. This c- prises the modeling of the evolution of internal variables in inelastic materials as well as the initiation and development of material patterns and microstructures. The IUTAM Symposium on "Variational Concepts with Applications to the - chanics of Materials" took place at the Ruhr-University of Bochum, Germany, on September 22-26, 2008. The symposium was attended by 55 delegates from 10 countries. Altogether 31 lectures were presented. The objective of the symposium was to give an overview of the new dev- opments sketched above, to bring together leading experts in these ?elds, and to provide a forum for discussing recent advances and identifying open problems to work on in the future. The symposium focused on the developmentof new material models as well as the advancement of the corresponding computational techniques. Speci?c emphasis is put on the treatment of materials possessing an inherent - crostructure and thus exhibiting a behavior which fundamentally involves multiple scales. Among the topics addressed at the symposium were: 1. Energy-based modeling of material microstructures via envelopes of n- quasiconvex potentials and applications to plastic behavior and pha- transformations.

This book addresses the need for a fundamental understanding of the physical origin, the mathematical behavior and the numerical treatment of models which include microstructure. Leading scientists present their efforts involving mathematical analysis, numerical analysis, computational mechanics, material modelling and experiment. The mathematical analyses are based on methods from the calculus of variations, while in the numerical implementation global optimization algorithms play a central role. The modeling covers all length scales, from the atomic structure up to macroscopic samples. The development of the models ware guided by experiments on single and polycrystals and results will be checked against experimental data.

This book introduces non-identifier-based adaptive control (with and without internal model) and its application to the current, speed and position control of mechatronic systems such as electrical synchronous machines, wind turbine systems, industrial servo systems, and rigid-link, revolute-joint robots. In mechatronics, there is often only rough knowledge of the system. Due to parameter uncertainties, nonlinearities and unknown disturbances, model-based control strategies can reach their performance or stability limits without iterative controller design and performance evaluation, or system identification and parameter estimation. The non-identifier-based adaptive control presented is an alternative that neither identifies the system nor estimates its parameters but ensures stability. The adaptive controllers are easy to implement, compensate for disturbances and are inherently robust to parameter uncertainties and nonlinearities. For controller implementation only structural system knowledge (like relative degree, input-to-state stable zero dynamics and known sign of the high-frequency gain) is required. Moreover, the presented controllers guarantee reference tracking with prescribed asymptotic or transient accuracy, i.e. the tracking error eventually tends to or for all time evolves within an a priori specified region. The book presents the theory, modeling and application in a general but detailed and self-contained manner, making it easy to read and understand, particularly for newcomers to the topics covered

An intensive development of the theory of generalized analytic functions started when methods of Complex Analysis were combined with methods of Functional Analysis, especially with the concept of distributional solutions to partial differential equations. The power of these interactions is far from being exhausted. In order to promote the further development of the theory of generalized analytic functions and applications of partial differential equations to Mechanics, the Technical University of Graz organized a conference whose Proceedings are contained in the present volume. The contributions on generalized analytic functions (Part One) deal not only with problems in the complex plane (boundary value and initial value problems), but also related problems in higher dimensions are investigated where both several complex variables and the technique of Clifford Analysis are used. Part Two of the Proceedings is devoted to applications to Mechanics. It contains contributions to a variety of general methods such as L p-methods, boundary elements and asymptotic methods, and hemivariational inequalities. A substantial number of the papers of Part Two, however, deals with problems in Ocean Acoustics. The papers of both parts of the Proceedings can be recommended to mathematicians, physicists, and engineers working in the fields mentioned above, as well as for further reading within graduate studies.

For fifty-something Gail Lockwood the new millennium starts with redundancy. Her to-do list reads, 'Get a job. Pay off the suite. Do roots and nails. Get a man and get laid.' Not easy when her boss, the flamboyant Bradley Jones, has jetted off to Spain, and the job centre has nothing for a woman whose only qualification is a Brownie badge. Gail finds herself unemployed and firmly sandwiched between her eccentric mother and her problem daughter, Tamsin, a single mother who always seems to need last minute babysitting. But as she navigates through the job market, her mother's suspicious new boyfriend and an accident that brings her old boss back into her life, Gail starts to realize that sometimes, the most important things in life can't be put on a to-do list. Will Gail be able to navigate the ups and downs while still achieving everything on her list?

This edited volume explores how primary school teachers create rich opportunities for science learning, higher order thinking and reasoning, and how the teaching of science in Australia, Germany and Taiwan is culturally framed. It draws from the international and cross-cultural science education study EQUALPRIME: Exploring quality primary education in different cultures: A cross-national study of teaching and learning in primary science classrooms. Video cases of Year 4 science teaching were gathered by research teams based at Edith Cowan University, Deakin University, the Freie Universitat Berlin, the National Taiwan Normal University and the National Taipei University of Education. Meetings of these research teams over a five year period at which data were shared, analysed and interpreted have revealed significant new insights into the social and cultural framing of primary science teaching, the complexities of conducting cross-cultural video-based research studies, and the strategies and semiotic resources employed by teachers to engage students in reasoning and meaning making. The book's purpose is to disseminate the new insights into quality science teaching and how it is framed in different cultures; methodological advancements in the field of video-based classroom research in cross-cultural settings; and, implications for practice, teacher education and research. "The chapters (of this book) address issues of contemporary relevance and theoretical significance: embodiment, discursive moves, the social unit of learning and instruction, inquiry, and reasoning through representations. Through all of these, the EQUALPRIME team manages to connect the multiple cultural perspectives that characterise this research study. The 'meta-reflection' chapters offer a different form of connection, linking cultural and theoretical perspectives on reasoning, quality teaching and video-based research methodologies. The final two chapters offer connective links to implications for practice in teacher education and in cross-cultural comparative research into teaching and learning. These multiple and extensive connections constitute one of the books most significant accomplishments. The EQUALPRIME project, as reported in this book, provides an important empirical base that must be considered by any system seeking to promote sophisticated science learning and instructional practices in primary school classrooms. By exploring the classroom realisation of aspirational science pedagogies, the EQUALPRIME project also speaks to those involved in teacher education and to teachers. I commend this book to the reader. It offers important insights, together with a model of effective, collegial, collaborative inter-cultural research. It will help us to move forward in important ways". Professor David Clarke, Melbourne University

Homogenization is a fairly new, yet deep field of mathematics which is used as a powerful tool for analysis of applied problems which involve multiple scales. Generally, homogenization is utilized as a modeling procedure to describe processes in complex structures. Applications of Homogenization Theory to the Study of Mineralized Tissue functions as an introduction to the theory of homogenization. At the same time, the book explains how to apply the theory to various application problems in biology, physics and engineering. The authors are experts in the field and collaborated to create this book which is a useful research monograph for applied mathematicians, engineers and geophysicists. As for students and instructors, this book is a well-rounded and comprehensive text on the topic of homogenization for graduate level courses or special mathematics classes. Features: Covers applications in both geophysics and biology. Includes recent results not found in classical books on the topic Focuses on evolutionary kinds of problems; there is little overlap with books dealing with variational methods and T-convergence Includes new results where the G-limits have different structures from the initial operators

National majorities and their governments often demand that immigrants and other minorities must be "good": they should work hard, contribute to society, and adapt to dominant cultural norms. Such stereotypical labels for national outsiders, ranging from "good immigrants" to "good Muslims" and "model minorities", imply that their inclusion and recognition becomes conditional on fulfilling certain standards of behaviour and identity that are predetermined by the national majority. The affected minorities respond in diverse ways, at times striving to be recognised as "good" and at times rejecting these regimes of conditional inclusion and citizenship openly. This book offers ground-breaking insights on how these dynamics of conditional inclusion and "good" citizenship play out today, with a focus on migrant and immigrant-origin minorities in Europe and the Americas. This book shows that conditional inclusion is a globally widespread tool for controlling and rank-ordering minorities. As immigrants respond through diverse struggles for inclusion and recognition, these struggles reveal a hidden battleground of citizenship on which minorities negotiate who can be included and accepted in a given state or society. Their experience shows that conditionality is not an outlier of citizenship, but rather one of its universal core principles. This book was originally published as a special issue of Ethnic and Racial Studies.

The book presents the latest findings in experimental plasticity, crystal plasticity, phase transitions, advanced mathematical modeling of finite plasticity and multi-scale modeling. The associated algorithmic treatment is mainly based on finite element formulations for standard (local approach) as well as for non-standard (non-local approach) continua and for pure macroscopic as well as for directly coupled two-scale boundary value problems. Applications in the area of material design/processing are covered, ranging from grain boundary effects in polycrystals and phase transitions to deep-drawing of multiphase steels by directly taking into account random microstructures.

The two stories contained in this edition - "Love at First Sight: A Recollection" and "History of a Promise" - reveal Erich Hackl's unique and luminous perspective on the relationship between historical reality and literary representation. Drawing on historical documents and authentic individuals, Hackl portrays the inspiring lives of those who have suffered the terror and injustice of twentieth-century fascism. Recovering from a wound sustained as a result of his involvement with the International Brigade in the Spanish Civil War, the Austrian Karl Sequens falls in love with Herminia Roudiere Perpina, a strong and scrupulous Spanish woman who cared for him in the hospital. The story of their brief but enduring love both for each other and for social justice is narrated through the memory of their daughter Rosa Maria in "Love at First Sight: A Recollection". In his touching portrait of the fate of these non-fictional individuals, Erich Hackl illuminates an alternate perspective on Austria's position in the frenzied social and political configurations that mark Europe from the 1920s to the 1990s.;In "History of a Promise," the mind of the septuagenarian protagonist Willi retraces a path from his poverty in the Vienna of the First Republic through his internment in the concentration camps to his entrepreneurial success in his chosen South American exile as he reveals for the first time a promise that he had made.

The Libor Market Model (LMM) is a mathematical model for pricing and risk management of interest rate derivatives and has been built on the framework of modelling forward rates. For the conceptual understanding of the model a strong background in the fields of mathematics, statistics, finance and especially for implementation, computer science is necessary. The book provides the ne cessary groundwork to understand the LMM and delivers a framework to implement a working model where possible calibration and parameterization methods for volatility and correlation are explained. Special emphasis lies also on the trade off of speed and correctness where differences in choosing random number generators and the advantages of factor reduction are shown.

Structural change is a fundamental concept in economic model building. Statistics and econometrics provide the tools for identification of change, for estimating the onset of a change, for assessing its extent and relevance. Statistics and econometrics also have de veloped models that are suitable for picturing the data-generating process in the presence of structural change by assimilating the changes or due to the robustness to its presence. Important subjects in this context are forecasting methods. The need for such methods became obvious when, as a consequence of the oil price shock, the results of empirical analyses suddenly seemed to be much less reliable than before. Nowadays, economists agree that models with fixed structure that picture reality over longer periods are illusions. An example for less dramatic causes than the oil price shock with similarly profound effects is economic growth and its impacts on the economic system. Indeed, economic growth was a motivating concept for this volume. In 1983, the International Institute for Applied Systems Analysis (IIASA) in Laxen burg/ Austria initiated an ambitious project on "Economic Growth and Structural Change.""

This book includes many of the papers presented at the 6th International workshop on Model Oriented Data Analysis held in June 2001. This series began in March 1987 with a meeting on the Wartburg near Eisenach (at that time in the GDR). The next four meetings were in 1990 (St Kyrik monastery, Bulgaria), 1992 (Petrodvorets, St Petersburg, Russia), 1995 (Spetses, Greece) and 1998 (Marseilles, France). Initially the main purpose of these workshops was to bring together leading scientists from 'Eastern' and 'Western' Europe for the exchange of ideas in theoretical and applied statistics, with special emphasis on experimental design. Now that the sep aration between East and West is much less rigid, this exchange has, in principle, become much easier. However, it is still important to provide opportunities for this interaction. MODA meetings are celebrated for their friendly atmosphere. Indeed, dis cussions between young and senior scientists at these meetings have resulted in several fruitful long-term collaborations. This intellectually stimulating atmosphere is achieved by limiting the number of participants to around eighty, by the choice of a location in which communal living is encour aged and, of course, through the careful scientific direction provided by the Programme Committee. It is a tradition of these meetings to provide low cost accommodation, low fees and financial support for the travel of young and Eastern participants. This is only possible through the help of sponsors and outside financial support was again important for the success of the meeting."

Stirring, poignant stories humanize great historical tragedies with interviews and accounts of individuals affected by the clashes of communism and fascism. “Powerful inquiries spurred by photos—history made flesh, the untold lives of the mostly forgotten.” —Kirkus Reviews “A missionary voice of human dignity.” —World Literature Today Erich Hackl, 2017 recipient of the internationally-recognized Human Rights Award of Upper Austria and winner of multiple literature prizes, brings three little-known and inspiring biographies to light: young Gisela Tschofenig’s hidden life in the Austrian resistance and her fate; a fragmented interview with Wilhelm Brasse, the Polish political prisoner who photographed Auschwitz inmates and saved evidence of Mengele’s horrific crimes; and the multi-generational story of the Klagsbrunns, who fled Nazism in Vienna only to find another kind of terror in the fascist dictatorship of 1950s Brazil.
