Abstract

In dieser Arbeit wurden Risswiderstandskurven (R-Kurven) für vier verschiedene Siliciumnitridkeramiken gemessen. Die R-Kurven zeigen einen sehr steilen Anstieg und erreichen nahezu den Plateauwert in 10 bis 20µm Rissverlängerung. Aus den R-Kurven wurden mit Hilfe der Gewichtsfunktion die jeweiligen Brückenspannungsverteilungen berechnet. Des Weiteren wurde ein neuer Ansatz zur Beschreibung der Verstärkungsmechanismen in Siliciumnitridkeramiken herausgearbeitet.

Abstract

The long reign of Ivan Aleksand&#259;r (1331-1371), the penultimate emperor of Bulgaria prior to the Turkish conquest, was marked by a series of successful military campaigns against Serbia and Byzantium and above all by an intensive cultural production, largely fostered and funded by the sovereign himself. The central decades of the fourteenth century were of crucial importance for the later cultural evolution of Bulgaria and the whole of Orthodox Slovenia, despite which to date ample and exhaustive studies on the figure of Ivan Aleksand&#259;r are lacking. There is, in effect, a considerable amount of information at disposal, although it is scattered over the literary sources, the colophons of the manuscripts, the epigraphic documentation and also, obviously, the official deeds promulgated by the Emperor. Through the analysis of this varied documentation, this book attempts to reconstruct the figure of the sovereign, the context in which he lived and worked, his greatness and his mistakes and his parallel activities as a strategist and an illuminated patron of the arts. For the first time, the Italian reader can find collected and translated all the manuscript sources relating to the Bulgarian sovereign. The book is completed by an appendix with the original texts of the Slavonic-ecclesiastical tradition.

Abstract

In this work, the fracture toughness is predicted by means of a method based on tests using sub-size specimens. For this purpose, the fracture process including crack growth is described using FEM and cohesive zone model. The tests on sub-size specimens are used for parameter identification. With this set of parameters a standard-size specimen can be simulated. The predicted fracture toughness based on this standard-size specimen meets the size-requirements of the applicable standard.

Abstract

Most ceramics show an increase of the crack growth resistance during crack propagation (R-curve behaviour). Reasons for such behaviour are bridging effects between opposite crack surfaces, phase transformations around the tip of a crack, and development of micro-cracking zones. This booklet predominantly deals with the bridging behaviour and the discussion of the observed effects in terms of the fracture mechanics weight function procedure.

Abstract

"In The Contest between B-Genres, the “Space Trilogy” by J.R.R. Tolkien’s friend and colleague C.S. Lewis and the roster of American science fictions that Gotthard Günther selected and glossed for the German readership in 1952 demarcate the ring in which the contestants face off. In carrying out in fiction the joust that Tolkien proclaimed in his manifesto essay “On Fairy-Stories,” Lewis challenged the visions of travel through time and space that were the mainstays of modern science fiction. In the facing corner, Günther recognized in American science fiction the first stirrings of a new mythic storytelling that would supplant the staple of an expiring metaphysics, the fairy-story basic to Tolkien and Lewis’s fantasy genre. The B-genres science fiction and fantasy were contemporaries of cinema’s emergence out of the scientific and experimental study and recording of motion made visible. In an early work like H.G. Wells’s The Time Machine, which Tolkien credited as work of fantasy, the transport through time – the ununderstood crux of this literary experiment – is conveyed through a cinematic–fantastic component in the narrative, reflecting optical innovations and forecasting the movies to come. Although the historical onset of the rivalry between the B-genres is packed with literary examples, adaptation (acknowledged or not) followed out the rebound of wish fantasy between literary descriptions of the ununderstood and their cinematic counterparts, visual and special effects. The arrival of the digital relation out of the crucible of the unknown and the special effect seemed at last to award the fantasy genre the trophy in its contest with science fiction. And yet, although science fiction indeed failed to predict the digital future, fantasy did not so much succeed as draw benefit from the mere resemblance of fantasying to the new relation. While it follows that digitization is the fantasy that is true (and not, as Tolkien had hoped, the Christian Gospel), the newly renewed B-genre without borders found support in another revaluation that was underway in the other B-genre. Once its future orientation was “history,” science fiction began indwelling the ruins of its faulty forecasts. By its new allegorical momentum, science fiction supplied captions of legibility and history to the reconfigured borderlands it cohabited with fantasy. The second volume also attends, then, to the hybrids that owed their formation to these changes, both anticipated and realized. Extending through the topography of the borderlands, works by J.G. Ballard, Ursula Le Guin, and John Boorman, among others, occupy and cathect a context of speculative fiction that suspended and blended the strict contest requirements constitutive of the separate B-genres"

Abstract

This book provides an insight into the patterns of variation and change of rhotics in different languages and from a variety of perspectives. It sheds light on the phonetics, the phonology, the socio-linguistics and the acquisition of /r/-sounds in languages as diverse as Dutch, English, French, German, Greek, Hebrew, Italian, Kuikuro, Malayalam, Romanian, Slovak, Tyrolean and Washili Shingazidja thus contributing to the discussion on the unity and uniqueness of this group of sounds.

Abstract

What is the impact of information and communication technologies (ICTs) on the human condition? In order to address this question, in 2012 the European Commission organized a research project entitled The Onlife Initiative: concept reengineering for rethinking societal concerns in the digital transition. This volume collects the work of the Onlife Initiative. It explores how the development and widespread use of ICTs have a radical impact on the human condition.ICTs are not mere tools but rather social forces that are increasingly affecting our self-conception (who we are), our mutual interactions (how we socialise); our conception of reality (our metaphysics); and our interactions with reality (our agency). In each case, ICTs have a huge ethical, legal, and political significance, yet one with which we have begun to come to terms only recently.The impact exercised by ICTs is due to at least four major transformations: the blurring of the distinction between reality and virtuality; the blurring of the distinction between human, machine and nature; the reversal from information scarcity to information abundance; and the shift from the primacy of stand-alone things, properties, and binary relations, to the primacy of interactions, processes and networks.Such transformations are testing the foundations of our conceptual frameworks. Our current conceptual toolbox is no longer fitted to address new ICT-related challenges. This is not only a problem in itself. It is also a risk, because the lack of a clear understanding of our present time may easily lead to negative projections about the future. The goal of The Manifesto, and of the whole book that contextualises, is therefore that of contributing to the update of our philosophy. It is a constructive goal. The book is meant to be a positive contribution to rethinking the philosophy on which policies are built in a hyperconnected world, so that we may have a better chance of understanding our ICT-related problems and solving them satisfactorily.The Manifesto launches an open debate on the impacts of ICTs on public spaces, politics and societal expectations toward policymaking in the Digital Agenda for Europe’s remit. More broadly, it helps start a reflection on the way in which a hyperconnected world calls for rethinking the referential frameworks on which policies are built.

Abstract

This book analyzes the possibilities for effective global governance of science in Europe, India and China. Authors from the three regions join forces to explore how ethical concerns over new technologies can be incorporated into global science and technology policies. The first chapter introduces the topic, offering a global perspective on embedding ethics in science and technology policy. Chapter Two compares the institutionalization of ethical debates in science, technology and innovation policy in three important regions: Europe, India and China. The third chapter explores public perceptions of science and technology in these same three regions. Chapter Four discusses public engagement in the governance of science and technology, and Chapter Five reviews science and technology governance and European values. The sixth chapter describes and analyzes values demonstrated in the constitution of the People’s Republic of China. Chapter Seven describes emerging evidence from India on the uses of science and technology for socio-economic development, and the quest for inclusive growth. In Chapter Eight, the authors propose a comparative framework for studying global ethics in science and technology. The following three chapters offer case studies and analysis of three emerging industries in India, China and Europe: new food technologies, nanotechnology and synthetic biology. Chapter 12 gathers all these threads for a comprehensive discussion on incorporating ethics into science and technology policy. The analysis is undertaken against the backdrop of different value systems and varying levels of public perception of risks and benefits. The book introduces a common analytical framework for the comparative discussion of ethics at the international level. The authors offer policy recommendations for effective collaboration among the three regions, to promote responsible governance in science and technology and a common analytical perspective in ethics.

Abstract

Universities and research institutes are increasingly expected to contribute to society by creating innovation from the returns of their research results and the establishment of new technologies. Toward that goal, Keio University in Japan held an international symposium titled “Fulfilling the Promise of Technology Transfer: Fostering Innovation for the Benefit of Society.” From that symposium the following contents are included in the present volume: 1) A showcase of ideas and case studies to promote future creation of innovation by universities and research institutes worldwide, including information on the R&D value chain, licensing, income generation, start-ups and mechanisms to encourage entrepreneurship, and the changing role of universities in fostering innovation. 2) Introduction of active research projects that aim to productize successful research results on an international level. For example, the book includes results of research on stem cell technologies and regenerative medicine as well as the realization and application of polymer photonics and the development of the core technology of polymer photonics. 3) Case studies from the U.K. in developing industry–academia collaboration with various business partners ranging from start-ups and spinout companies to large enterprises. 4) Reports of the achievements of the technological transfer activities at Keio University supported by the 5-year public fund, with suggestions for future prospects.
