Book excerpt: Inhaltsangabe:Einleitung: Integration von Elektronik in Textilien ist ein Thema, das zunehmend in den Blickpunkt verschiedener Forschungsinstitute und Unternehmen rückt. Für diese sehr aktuelle Technik werden allerdings bisher nur herkömmliche Methoden der Verdrahtung verwendet. Um die Beschaffenheit eines Textils nicht zu verändern, und damit den Tragekomfort und das Erscheinungsbild nicht negativ zu beeinflussen, müssen neue Technologien verwendet werden. Ein Ansatz ist die Verwendung von gesticktem, elektrisch leitfähigem Garn. Dieses hat die gleichen mechanischen Eigenschaften wie herkömmliche Garne und stellt damit keinen Fremdkörper in einem Textil dar. Zusätzlich leitet es den elektrischen Strom und kann direkt durch Sticken mit einem elektronischen Modul verbunden werden. Dadurch dient das Garn als elektrischer Leiter für Signale und kann gleichzeitig eine Verbindung zu elektronischen Modulen herstellen. In vorangegangenen Forschungsprojekten wurde die Machbarkeit und Zuverlässigkeit von gestickten Kontakten untersucht. Es hat sich gezeigt, dass das Ankontaktieren und Verbinden von Substraten mit elektrisch leitfähigen Fäden eine mögliche Alternative zu den herkömmlichen Verdrahtungstechniken darstellt. Allerdings zeigten sich starke Schwankungen und auch Ausfälle der gemessenen Kontakwiderstände während der Zuverlässigkeitstests. Die vorliegende Arbeit befasst sich mit den Ursachen der Widerstandschwankungen und Ausfälle von gestickten Kontakten. Ziel ist es, diese zu analysieren und gezielt Verbesserungsvorschläge zu machen. Die erhöhte Zuverlässigkeit der verbesserten Kontakte soll abschließend im Experiment validiert werden. Anfangs werden die thermomechanischen und elektrischen Eigenschaften des verwendeten Garns analysiert und der Zusammenhang beider Größen erläutert. Dies geschieht auf Basis von thermomechanischen Analysen und Widerstandsmessungen, sowohl bei konstanter Temperatur als auch im Temperaturzyklentest. Weiterhin werden die gestickten Kontakte betrachtet. Das verwendete Messverfahren und ein theoretisches Modell des Kontaktwiderstands werden vorgestellt. Um die Einflussgrößen des gestickten Kontakts zu reduzieren, wird ein vereinfachtes physikalisches Modell eingeführt. Beide Strukturen werden anschließend in Temperaturzyklentests mit In-situ-Messsystemen untersucht. Die Ergebnisse des Experiments zeigen, dass sich der Widerstand der Kontakte anfangs verbessert, dann aber mit der Zeit verschlechtert. Die Degradation [...]

Available in PDF, EPUB and Kindle. Book excerpt: A sweeping history of the passionate men and women in uniform who have bravely and courageously exercised the power of dissent Before the U.S. Constitution had even been signed, soldiers and new veterans protested. Dissent, the hallowed expression of disagreement and refusal to comply with the government’s wishes, has a long history in the United States. Soldier dissenters, outraged by the country’s wars or egregious violations in conduct, speak out and change U.S. politics, social welfare systems, and histories. I Ain’t Marching Anymore carefully traces soldier dissent from the early days of the republic through the wars that followed, including the genocidal “Indian Wars,” the Civil War, long battles against slavery and racism that continue today, both World Wars, Korea, Vietnam, the Cold War, and contemporary military imbroglios. Acclaimed journalist Chris Lombardi presents a soaring history valorizing the brave men and women who spoke up, spoke out, and talked back to national power. Inviting readers to understand the texture of dissent and its evolving and ongoing meaning, I Ain’t Marching Anymore profiles conscientious objectors including Frederick Douglass’s son Lewis, Evan Thomas, Howard Zinn, William Kunstler, and Chelsea Manning, adding human dimensions to debates about war and peace. Meticulously researched, rich in characters, and vivid in storytelling, I Ain’t Marching Anymore celebrates the sweeping spirit of dissent in the American tradition and invigorates its meaning for new risk-taking dissenters.

Available in PDF, EPUB and Kindle. Book excerpt: 'A landmark in the process of decolonizing imperial Western knowledge.' Walter Mignolo, Duke University To the colonized, the term 'research' is conflated with European colonialism; the ways in which academic research has been implicated in the throes of imperialism remains a painful memory. This essential volume explores intersections of imperialism and research - specifically, the ways in which imperialism is embedded in disciplines of knowledge and tradition as 'regimes of truth.' Concepts such as 'discovery' and 'claiming' are discussed and an argument presented that the decolonization of research methods will help to reclaim control over indigenous ways of knowing and being. Now in its eagerly awaited second edition, this bestselling book has been substantially revised, with new case-studies and examples and important additions on new indigenous literature, the role of research in indigenous struggles for social justice, which brings this essential volume urgently up-to-date.

Available in PDF, EPUB and Kindle. Book excerpt: A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.

Available in PDF, EPUB and Kindle. Book excerpt: Smart-textiles developers draw on diverse fields of knowledge to produce unique materials with enhanced properties and vast potential. Several disciplines outside the traditional textile area are involved in the construction of these smart textiles, and each individual field has its own language, specific terms and approaches. Multidisciplinary know-how for smart-textiles developers provides a filtered knowledge of these areas of expertise, explaining key expressions and demonstrating their relevance to the smart-textiles field.Following an introduction to the new enabling technologies, commercialisation and market trends that make up the future of smart-textiles development, part one reviews materials employed in the production of smart textiles. Types and processing of electro-conductive and semiconducting materials, optical fibres for smart photonic textiles, conductive nanofibres and nanocoatings, polymer-based resistive sensors, and soft capacitance fibres for touch-sensitive smart textiles are all discussed. Part two then investigates such technologies as the embedding of electronic functions, the integration of thin-film electronics, and the development of organic and large-area electronic (OLAE) technologies for smart textiles. Joining technologies are also discussed, alongside kinetic, thermoelectric and solar energy harvesting technologies, and signal processing technologies for activity-aware smart textiles. Finally, product development and applications are the focus of part three, which investigates strategies for technology management, innovation and improved sustainability, before the book concludes by exploring medical, automotive and architectural applications of smart textiles.With its distinguished editor and international team of expert contributors, Multidisciplinary know-how for smart-textiles developers is a key tool for readers working in industries including design, fashion, textiles, through to electronics, computing and material science. It also provides a useful guide to the subject for academics working across a wide range of fields. - Reviews materials used in the production of smart textiles - Examines the technologies used in smart textiles, such as optical fibres and polymer based resistive sensors - Investigates strategies for technology management, innovation and improved development

Book excerpt: The research field of smart textiles is currently witnessinga rapidly growing number of applicationsintegrating intelligent functions in textile substrates.With an increasing amount of new developed productprototypes, the number of materials used and that ofspecially designed production technologies are alsogrowing.This book is intended to provide an overview of materials,production technologies, and product conceptsto different groups concerned with smart textiles. Itwill help designers to understand the possibilities ofsmart textile production, so that they are enabled todesign this type of products. It will also help textileand electronics manufacturers to understand whichproduction technologies are suitable to meet certainproduct requirements.After an introduction to smart textiles and their marketrelevance, different material types for functionaltextiles are described along with their properties,application areas, and product examples. Specialattention is given to materials for the realization ofelectrical conductivity in textiles, as these are crucialfor the following overview on sensor and productiontechnologies. Next, textile-based sensors areintroduced. While numerous textile-based sensors,ranging from sensing fibers to coatings and three-dimensionalstructures, have been developed, theirspecific properties and usage are not clear. Bosowskiet al. have suggested a structure for a classified catalogueas knowledge basis to support the smart textileproduct development process. This chapter developsthe classification further and implements it in a catalogueto be used by practitioners from research andindustry when developing and designing textiles withsensing capabilities. The full catalogue is reported inthe appendix. The third part of the book starts by describingthe state of the art of research on productiontechnologies for the integration of conductive materialsinto textile substrates, which include weaving,knitting, embroidering, printing, without mentioningspecific products. Different variants of each technologyare presented. Additionally, associated technologiesto integrate electrical components in textile substratesare outlined. This part closes by reporting thecurrent state of research on automated productionsystems for electronics integration into textiles. In thelast part of the book, product and design conceptsfor smart textiles are evaluated along the example oftouchpads.

Available in PDF, EPUB and Kindle. Book excerpt: Purity and Danger is acknowledged as a modern masterpiece of anthropology. It is widely cited in non-anthropological works and gave rise to a body of application, rebuttal and development within anthropology. In 1995 the book was included among the Times Literary Supplement's hundred most influential non-fiction works since WWII. Incorporating the philosophy of religion and science and a generally holistic approach to classification, Douglas demonstrates the relevance of anthropological enquiries to an audience outside her immediate academic circle. She offers an approach to understanding rules of purity by examining what is considered unclean in various cultures. She sheds light on the symbolism of what is considered clean and dirty in relation to order in secular and religious, modern and primitive life.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a completely revised and rewritten edition of "Electric Contacts Handbook" published in 1958. A large number of new in vestigations are considered, and many of the basic theories are revised in detail and even in general. The body of information had to be limited as it was not advisable to increase the volume of the book. In particular, no attempt was made to cover all of the practical applications. They appear as examples following concentrated explanations of basic phenomena. As in several branches of technology, the solutions of problems ari sing in the field of electric contacts involve insight into various disci plines of physics. It is feit that reviews of some of those topics, especi ally adapted to electric contact phenomena, are welcome to many readers. For example, chapters have been devoted to the structure of carbon, the band theory of electric conduction in solids, certain pro blems in statistics, and the theory of the electric arc. As regards arc problems, new ideas have been introduced. In order to make the main text less cumbersome, such reviews are presented as appendices. Throughout this edition, the mksa-unit system is used in accord with the latest recommendation for standardization of units in scientific and technical writings. The chapter "History of Early Investigations on Contacts" forming Part IV in the preceding edition of 1958 has not been repeated in this book.

Available in PDF, EPUB and Kindle. Book excerpt: E. H. Gombrich's Little History of the World, though written in 1935, has become one of the treasures of historical writing since its first publication in English in 2005. The Yale edition alone has now sold over half a million copies, and the book is available worldwide in almost thirty languages. Gombrich was of course the best-known art historian of his time, and his text suggests illustrations on every page. This illustrated edition of the Little History brings together the pellucid humanity of his narrative with the images that may well have been in his mind's eye as he wrote the book. The two hundred illustrations—most of them in full color—are not simple embellishments, though they are beautiful. They emerge from the text, enrich the author's intention, and deepen the pleasure of reading this remarkable work. For this edition the text is reset in a spacious format, flowing around illustrations that range from paintings to line drawings, emblems, motifs, and symbols. The book incorporates freshly drawn maps, a revised preface, and a new index. Blending high-grade design, fine paper, and classic binding, this is both a sumptuous gift book and an enhanced edition of a timeless account of human history.
