Fleeing the Nazis, Theodor W. Adorno lived in New York City as a refugee from 1938 until 1941. During these years, he was intensively involved in a study of how the recently developed techniques for the nation-wide transmission of music over radio were transforming the perception of music itself. This broad ranging radio research was conceived as nothing less than an investigation, partly empirical, of Walter Benjamin's speculative claims for the emancipatory potential of art in the age of its mechanical reproduction. The results of Adorno's project set him decisively at odds with Benjamin's theses and at the same time became the body of thinking that formed the basis for Adornos own aesthetics in his Philosophy of New Music. Current of Music is the title that Adorno himself gave to this research project. For complex reasons, however, Adorno was not able to bring the several thousands of pages of this massive study, most of it written in English, to a final form prior to leaving New York for California, where he would immediately begin work with Max Horkheimer on the Dialectic of Enlightenment. Robert Hullot-Kentor, the distinguished Adorno scholar, reconstructed Adorno's project for the Adorno Archive in Germany and provides a lengthy and informative introduction to the fragmentary texts collected in this volume. Current of Music will be widely discussed for the light it throws on the development of Adorno's thought, on his complex relationship with Walter Benjamin, but most of all for the important perspectives it provides on questions of popular culture, the music of industrial entertainment, the history of radio and the social dimensions of the reproduction of art.

A generic DC grid model that is compatible with the standard AC system stability model is presented and used to analyse the interaction between the DC grid and the host AC systems. A multi-terminal DC (MTDC) grid interconnecting multiple AC systems and offshore energy sources (e.g. wind farms) across the nations and continents would allow effective sharing of intermittent renewable resources and open market operation for secure and cost-effective supply of electricity. However, such DC grids are unprecedented with no operational experience. Despite lots of discussions and specific visions for setting up such MTDC grids particularly in Europe, none has yet been realized in practice due to two major technical barriers: Lack of proper understanding about the interaction between a MTDC grid and the surrounding AC systems. Commercial unavailability of efficient DC side fault current interruption technology for conventional voltage sourced converter systems This book addresses the first issue in details by presenting a comprehensive modeling, analysis and control design framework. Possible methodologies for autonomous power sharing and exchange of frequency support across a MTDC grid and their impact on overall stability is covered. An overview of the state-of-the-art, challenges and on-going research and development initiatives for DC side fault current interruption is also presented.
