Bachelor Thesis from the year 2010 in the subject Communications - Multimedia, Internet, New Technologies, grade: 1, St. Pölten University of Applied Sciences, course: Grundlagen der Audiotechnik, language: English, abstract: High Bandwidth and the rapid development of social networks introduce a new way of making music together. The users of this new community are ambitious musicians and can log into online jam sessions to play together, overcoming the distance between them. Remote collaborative musical performances over the internet are already possible and there are numerous solutions out there. But all these solutions are dealing with one problem: Latency. This means, the audio signal of one user reaches the other user not in real time but lagged, which makes it impractical to make music together. It’s not feasible to eliminate Latency but it is feasible to reduce it. In this work I will define tolerable latency and I will outline possible problems which create latency in the audio conduction and recommend solutions, for keeping latency as low as possible. This includes both client-side difficulties like bandwidth, real time audio compression, buffer times, and problems in the server-side streaming architecture like transport protocols, synchronization, packet loss, and delay times.
Genetic Algorithms and Genetic Programming: Modern Concepts and Practical Applications discusses algorithmic developments in the context of genetic algorithms (GAs) and genetic programming (GP). It applies the algorithms to significant combinatorial optimization problems and describes structure identification using HeuristicLab as a platform for al
Symbolic regression (SR) is one of the most powerful machine learning techniques that produces transparent models, searching the space of mathematical expressions for a model that represents the relationship between the predictors and the dependent variable without the need of taking assumptions about the model structure. Currently, the most prevalent learning algorithms for SR are based on genetic programming (GP), an evolutionary algorithm inspired from the well-known principles of natural selection. This book is an in-depth guide to GP for SR, discussing its advanced techniques, as well as examples of applications in science and engineering. The basic idea of GP is to evolve a population of solution candidates in an iterative, generational manner, by repeated application of selection, crossover, mutation, and replacement, thus allowing the model structure, coefficients, and input variables to be searched simultaneously. Given that explainability and interpretability are key elements for integrating humans into the loop of learning in AI, increasing the capacity for data scientists to understand internal algorithmic processes and their resultant models has beneficial implications for the learning process as a whole. This book represents a practical guide for industry professionals and students across a range of disciplines, particularly data science, engineering, and applied mathematics. Focused on state-of-the-art SR methods and providing ready-to-use recipes, this book is especially appealing to those working with empirical or semi-analytical models in science and engineering.
Combating the Hydra explores structural as well as occasion-specific state violence committed by the early modern Habsburg Empire. The book depicts and analyzes attacks on marginalized people “maladjusted” of all sorts, women “of ill repute,” “heretic” Protestants, and “Gypsies.” Previously uncharted archival records reveal the use of arbitrary imprisonment, coerced labor, and deportation. The case studies presented provide insights into the origins of modern state power from varied techniques of population control, but are also an investigation of resistance against oppression, persecution, and life-threatening assaults. The spectrum of fights against debasement is a touching attestation of the humanity of the outcasts; they range from mental and emotional perseverance to counterviolence. A conversation with the eminent historian Carlo Ginzburg concludes the collection by asking about the importance of memorizing horrors of the past.
For years, the critique of capitalism was lost from public discourse; the very word "capitalism" sounded like a throwback to another era. Nothing could be further from the truth today. In this new intellectual atmosphere, Sociology, Capitalism, Critique is a contribution to the renewal of critical sociology, founded on an empirically grounded diagnosis of society's ills. The authors, Germany's leading critical sociologists-Klaus Drre, Stephan Lessenich, and Hartmut Rosa-share a conviction that ours is a pivotal period of renewal, in which the collective endeavour of academics can amount to an act of intellectual resistance, working to prevent any regressive development that might return us to neoliberal domination. The authors discuss key issues, such as questions of accumulation and expropriation; discipline and freedom; and the powerful new concepts of activation and acceleration. Their politically committed sociology, which takes the side of the losers in the current crisis, places society's future well-being at the centre of their research. Their collective approach to this project is a conscious effort to avoid co-optation in the institutional practices of the academy. These three differing but complementary perspectives serve as an insightful introduction to the contemporary themes of radical sociology in capitalism's post-crisis phase.
In the mountain of books that have been written about the Third Reich, surprisingly little has been said about the role played by the German nobility in the Nazis' rise to power. While often confidently referred to, the 'fateful' role played by the German nobility is rarely, if ever, investigated in any real detail. Nazis and Nobles now fills this gap, providing the first systematic investigation of the role played by the nobility in German political life between Germany's defeat in the First World War in 1918 and the consolidation of Nazi power in the 1930s. As Stephan Malinowski shows, the German nobility was too weak to prevent the German Revolution of 1918 but strong enough to take an active part in the struggle against the Weimar Republic. In a real twist of historical irony, members of the nobility were as prominent in the destruction of Weimar democracy as they were to be years later in Graf Stauffenberg's July 1944 bomb plot against Hitler. In this skilful portrait of an aristocratic world that was soon to disappear, Malinowski gives us for the first time the in-depth story of the German nobility's social decline and political radicalization in the inter-war years - and the troubled mésalliance to which this was to lead between the majority of Germany's nobles and the National Socialists.
There are only few discoveries and new technologies in physical sciences that have the potential to dramatically alter and revolutionize our electronic world. Topological insulators are one of them. The present book for the first time provides a full overview and in-depth knowledge about this hot topic in materials science and condensed matter physics. Techniques such as angle-resolved photoemission spectrometry (ARPES), advanced solid-state Nuclear Magnetic Resonance (NMR) or scanning-tunnel microscopy (STM) together with key principles of topological insulators such as spin-locked electronic states, the Dirac point, quantum Hall effects and Majorana fermions are illuminated in individual chapters and are described in a clear and logical form. Written by an international team of experts, many of them directly involved in the very first discovery of topological insulators, the book provides the readers with the knowledge they need to understand the electronic behavior of these unique materials. Being more than a reference work, this book is essential for newcomers and advanced researchers working in the field of topological insulators.

Memento mori—remember death—this is how the medieval monks exhort us. Our life, given in birth and taken by death, is radically marked by finitude, which can be a source of great fear and anguish. Our finitude, however, does not in itself need to be something negative. It confronts us with the question of our life’s meaning and spurs us on to treasure our days. Our contingency, as evidenced in our birth and death, reminds us that we have not made ourselves and that there is nothing necessary about the marvelous fact that we exist. Particularly from a Judeo-Christian perspective, embracing our finitude will mean gratefully accepting life as a completely gratuitous gift and living one’s days informed by a sense of this gratitude.
What factors determine the success of economic transition, development and growth? Examining the contrast between East German shock-therapy and Hungary's gradualism, the book generates a set of generalisable conditions for economic development which imply some degree of state intervention and strategy. A stability-oriented incomes policy and a carefully managed integration strategy can enable sustainable export surpluses, a competitive currency and macroeconomic stability, whilst providing sufficient room for economic restructuring, structural transformation and technological catch-up. The dangers of premature integration are examined.
This open access book traces the development of sociology in Germany from the late 19th century to the present day, providing a concise overview of the main actors, institutional processes, theories, methods, topics and controversies. Throughout the book, the author relates the disciplines history to its historical, economic, political and cultural contexts. The book begins with sociology in the German Reich, the Weimar Republic, National Socialism and exile, before exploring sociology after 1945 as a key discipline of the young Federal Republic of Germany, and reconstructing the periods from 1945 to 1968 and from 1968 to 1990. The final chapters are devoted to sociology in the German Democratic Republic and the period from 1990 to the present day. This work will appeal to students and scholars of sociology, and to a general readership interested in the history of Germany. Stephan Moebius is Professor of Sociological Theory and Intellectual History at the University of Graz, Austria.
Twelve-tone and serial music were dominant forms of composition following World War II and remained so at least through the mid-1970s. In 1961, Ann Phillips Basart published the pioneering bibliographic work in the field.
Black and Hispanic students are not learning enough in our public schools, and their typically poor performance is the most important source of ongoing racial inequality in America today—thus, say Abigail and Stephan Thernstrom, the racial gap in school achievement is the nation's most critical civil rights issue and an educational crisis; it's no wonder that "No Child Left Behind," the 2001 revision of the Elementary and Secondary Education Act, made closing the racial gap in education its central goal. An employer hiring the typical Black high school graduate or the college that admits the average Black student is choosing a youngster who has only an eighth-grade education. In most subjects, the majority of twelfth-grade Black students do not have even a "partial mastery" of the skills and knowledge that the authoritative National Assessment of Educational Progress calls "fundamental for proficient work" at their grade. No Excuses marshals facts to examine the depth of the problem, the inadequacy of conventional explanations, and the limited impact of Title I, Head Start, and other familiar reforms. Its message, however, is one of hope: Scattered across the country are excellent schools getting terrific results with high-needs kids. These rare schools share a distinctive vision of what great schooling looks like and are free of many of the constraints that compromise education in traditional public schools. In a society that espouses equal opportunity we still have a racially identifiable group of educational have-nots—young African Americans and Latinos whose opportunities in life will almost inevitably be limited by their inadequate education. When students leave high school without high school skills, their futures—and that of the nation—are in jeopardy. With successful schools already showing the way, no decent society can continue to turn a blind eye to such racial and ethnic inequality.
Judges often behave in surprising ways when they re-interpret laws and constitutions. Contrary to existing expectations, judges regularly abandon their own established interpretations in favor of new understandings. In Reconstructing Rights, Stephan Stohler offers a new theory of judicial behavior which demonstrates that judges do not act alone. Instead, Stohler shows that judges work in a deliberative fashion with aligned partisans in the elected branches to articulate evolving interpretations of major statutes and constitutions. Reconstructing Rights draws on legislative debates, legal briefs, and hundreds of judicial opinions issued from high courts in India, South Africa, and the United States in the area of discrimination and affirmative action. These materials demonstrate judges' willingness to provide interpretative leadership. But they also demonstrate how judges relinquish their leadership roles when their aligned counterparts disagree. This pattern of behavior indicates that judges do not exercise exclusive authority over constitutional interpretation. Rather, that task is subject to greater democratic influence than is often acknowledged.
The beauty of science may be pure and eternal, but the practice of science costs money. And scientists, being human, respond to incentives and costs, in money and glory. Choosing a research topic, deciding what papers to write and where to publish them, sticking with a familiar area or going into something new—the payoff may be tenure or a job at a highly ranked university or a prestigious award or a bump in salary. The risk may be not getting any of that. At a time when science is seen as an engine of economic growth, Paula Stephan brings a keen understanding of the ongoing cost-benefit calculations made by individuals and institutions as they compete for resources and reputation. She shows how universities offload risks by increasing the percentage of non-tenure-track faculty, requiring tenured faculty to pay salaries from outside grants, and staffing labs with foreign workers on temporary visas. With funding tight, investigators pursue safe projects rather than less fundable ones with uncertain but potentially path-breaking outcomes. Career prospects in science are increasingly dismal for the young because of ever-lengthening apprenticeships, scarcity of permanent academic positions, and the difficulty of getting funded. Vivid, thorough, and bold, How Economics Shapes Science highlights the growing gap between the haves and have-nots—especially the vast imbalance between the biomedical sciences and physics/engineering—and offers a persuasive vision of a more productive, more creative research system that would lead and benefit the world.

While the fledgling German paratroop operations in Belgium and the Netherlands in 1940, and on Crete in 1941, attracted worldwide attention, what is not as well known is that the use of paratroopers was planned for the invasion of Poland in 1939, in an act that began the Second World War. This has given rise to the myth that Adolf Hitler wanted to keep this new, and hitherto little-known, branch of the armed services secret for future projects.However, on several occasions the men of Parachute Regiment 1 were sat ready in their Ju52 transport planes, fully equipped and ready to go. 'Operation Fall Weiss' describes the role of the German paratroopers in the Polish campaign, using war diaries, maps, contemporary documents and photographs, including those from various private collections around the world.
