Analog and Hybrid Computer Programming De Gruyter graduate./ Bernd Ulmann.
No full textIn English.Includes bibliographical references and index.Analog and hybrid computing recently have gained much interest as analog computers can outperform classical stored-program digital computers in some areas by orders of magnitude. This book gives a thorough introduction to analog and hybrid computer programming by means numerous worked examples from various areas. It is based on a number of introductory and advanced lectures on this topic delivered by the author at several universities.Frontmatter -- Acknowledgments and disclaimer -- Contents -- 1.

Analog Computing - past, present, future?
No full textAs classic stored-program digital computers are reaching physical and practical limits with respect to clock frequency, integration density, and suffer from problems like Amdahl's law, unconventional approaches to high-speed and/or high-energy-efficient computing can offer a path to more computing power at lower power consumption.One of these approaches are analog computers which solve problems by means of analog electronic models of the underlying mathematical equations. Largely forgotten since the late 1970s, analog computers are about to return in the form of fully reconfigurable integrated circuits. Coupling these with traditional digital computers yields so-called hybrid computers which combine the best of two worlds, the programmability and vast program libraries available for digital computers as well as the high performance and low power consumption of analog computers. This talk briefly covers the history of analog computing, gives examples of current applications and future developments.
About the speaker
Bernd Ulmann is a professor for business computer science at the FOM University of Applied Sciences in Frankfurt/Germany. He studied mathematics and philosophy at the university of Mainz, He received his PHD at the university of Hamburg for a thesis about history and technology of analog computing.
Since 2000 he maintains a museum with mainframes and a world-wide unique collection of analog computers in Germany. He recently presented the on-board control system for the german A4/V2 rocket and Helmut Hoelzer's first general purpose analog computer at the NASA Apollo 11 50th anniversary in Huntsville.
Bernd Ulmann is author of several books in the field of analog computing. In 1999 he founded the company Raven Technology GmbH - today incorporating the team of Analog Paradigm (http://analogparadigm.com), which is developing and selling analog and hybrid computers.
Today he is one of few world-wide renowned experts for analog computing technology.</p
Violence et culture politique en Allemagne entre les deux guerres
No full textViolence and political culture in interwar Germany, Bernd Weisbrod.
The entire German political culture has since 1918 integrated the acceptation of violence. The author follows the fatal consequences of this failing in the Weimar period, through the action of the Freikorps (Corps francs), then under the Third Reich. The banalization of evil in Germany (H. Arendt) was also a characteristic of the political culture.Weisbrod Bernd. Violence et culture politique en Allemagne entre les deux guerres.

Perspektiven einer theologischen Disziplin
No full textReferring to Habermas' »structural transformation of the public sphere«, written in 1962, the author describes the characteristics of »public sphere« and deals with the current function and challenges of religious education. Religious education is understood as both the practice of teaching religion and a theory in the framework of theology and is meant to be of public interest from the public's viewpoint as well as from a religious view of the world
Nutzen von Bildungsberatung: konzeptionelle Eckpunkte vor dem Hintergrund britischer Forschungsergebnisse
No full textFirstly, the author explores the terminological field covering the outcome of educational counselling and develops beneficial dimensions, which are visualised as a network. The author stimulates the German discussion with methodological topics and research results originating in British evaluations. Scientific studies used to confirm the positive effects of educational counselling. Finally the report suggests an agenda for researching the benefits in the field of counselling in continuing education.Da Politik -zumal in der Bildung- zunehmend evidenzbasiert agieren möchte, wächst der Bedarf an belastbaren Indikatoren für Nutzen und Wirksamkeit von Investitionen. Diese Diskussion wird auch auf die Weiterbildungsberatung zukommen. Da der Diskurs um Nutzenarten von Beratung hierzulande noch ganz am Anfang steht, hat sich Bernd Käpplinger in Großbritannien umgesehen und von dort Anregungen geholt, die er in die Skizzierung von Nutzendimensionen von Weiterbildungsberatung einfließen lässt
Bernd Fabritius: Rotkäppchen, was trägst du unter der Schürze? Geschlechterbilder im Märchen. Marburg: Tectum Wissenschaftsverlag, 2010
No full textAus geschlechterpädagogischer und soziologischer Perspektive durchleuchtet Bernd Fabritius in seiner knappen Monographie die Beziehungen von weiblichen und männlichen Charakteren in Märchen. Anhand verschiedener Versionen des Rotkäppchen-Motives analysiert er, wie in diesen reale Geschlechterverhältnisse und -rollen widergespiegelt werden und welche erzieherischen Funktionen die Märchen haben. Der Autor fragt danach, wie eine sinnvolle pädagogische Nutzung von Märchen aus heutiger Sicht aussehen soll.In his concise monograph, Bernd Fabritius examines the relationships of female and male fairy tale characters from a gender pedagogical and a sociological perspective. Using several versions of the Little Red Riding Hood motif, he analyzes how these reflect actual gender relations and gender roles and he also investigates the educational function of the fairy tales. Afterwards, the author asks what a valuable pedagogical use of fairy tales should look like from a present-day perspective
A Manifesto of Nodalism
No full textThis paper proposes the notion of Nodalism as a means describing contemporary culture and of understanding my own creative practice in electronic music composition. It draws on theories and ideas from Kirby, Bauman, Bourriaud, Deleuze, Guatarri, and Gochenour, to demonstrate how networks of ideas or connectionist neural models of cognitive behaviour can be used to contextualize, understand and become a creative tool for the creation of contemporary electronic music
