  • Download Elektrische Maschinen: Fünfter Band: Stromwendermaschinen by Rudolf Richter PDF

    By Rudolf Richter

    Der V. Band, mit dem das Sammelwerk der Elektrischen Maschinen abschliesst, lag schon Anfang 1945 zum grossen Teil fertig gedruckt vor, als er durch Bombenangriff in der Druckerei mit allen Unterlagen ver nichtet wurde. Im wesentlichen ungeandert liegt nun der Neudruck vor. Der V. Band behandelt die einphasigen (Abschn. I) und die mehr phasigen (II) Maschinen mit Stromwender sowie die Regelsatze mit Induktionsmaschine als Vordermaschine (III). In den einleitenden Abschnitten I A und II A wird zunachst der Laufer mit Stromwender im Wechselfelde und im Drehfelde besprochen. Dabei werden die Grundlagen fur das Verhalten und die Berechnung der Maschinen behandelt. Die nachsten Abschnitte sind dann den ver schiedenen Maschinenarten gewidmet. Es folgen. 'Untersuchungen uber Selbsterregung und schliesslich, wie in den ubrigen Banden, Abschnitte uber die experimentelle Untersuchung und den Entwurf. Besondere Berucksichtigung findet die Funkenunterdruckung sowohl in den ein fuhrenden Abschnitten A als auch bei Betrachtung der verschiedenen Maschinenarten. Bei den einphasigen Maschinen (Abschn. I) steht der Reihenschluss motor, wie er fur Vollbahnen verwendet wird, im Vordergrund der Betrachtungen. Die meisten Berechnungsbeispiele beziehen sich auf 2 diesen Motor bei sixteen / Hz Netzfrequenz. Ausserdem werden aber auch three die andern Maschinenarten, wie z. B. die Repulsionsmotoren mit ihren Abarten, Reihenschluss-Repulsionsmotoren und Maschinen mit Neben schlusseigenschaften, ausfuhrlich beh

  • Download Chameleo: A Strange but True Story of Invisible Spies, by Robert Guffey PDF

    By Robert Guffey

    A spell binding mixture of Charles Bukowski, Hunter S. Thompson, and Philip okay. Dick, Chameleo is a real account of what occurred in a seedy Southern California city whilst an enthusiastic and unrepentant heroin addict named Dion Fuller sheltered a U.S. Marine who’d stolen evening imaginative and prescient goggles and maybe a couple of most sensible mystery documents from a close-by army base.

    Dion stumbled on himself arrested (under the ostensible auspices of The Patriot Act) for conspiring with overseas terrorists to smuggle most sensible mystery army gear out of Camp Pendleton. the truth that Dion had totally not anything to do with foreign terrorists, smuggling, best mystery army apparatus, or Camp Pendleton didn’t appear to hassle the army. He used to be published from reformatory after a six-day-long Abu-Ghraib-style interrogation. thus, he believed himself below severe govt scrutiny — and, he suspected, the topic of unusual experimentation concerning “cloaking”— electro-optical camouflage so severe it renders observers virtually invisible from a distance of a few meters — by means of the dept of native land protection. Hallucination? maybe — other than Robert Guffey, an English instructor and Dion’s buddy, tracked down and interviewed one of many scientists in the back of the undertaking codenamed “Chameleo,” experimental expertise which appears to be like to were stolen via the U.S. division of safety and deployed on American soil. extra surprising nonetheless, Guffey stumbled on that the DoD has been experimenting with its most modern applied sciences on a few American citizens.

    A condensed model of this tale used to be the canopy function of Fortean occasions journal (September 2013).

  • Download Nanotechnology and the Public: Risk Perception and Risk by Susanna Hornig Priest PDF

    By Susanna Hornig Priest

    From nuclear strength to gene remedy to the auto, historical past indicates that it's worthy to motivate and facilitate public dialogue approximately new applied sciences and their strength risks. a part of the sequence Perspectives in Nanotechnology, Nanotechnology and the general public: possibility belief and chance conversation assesses effects from concentration teams, interviews, and different assets to supply a extra nuanced knowing of the way non-experts understand nanotechnology and what they anticipate from it.

    Includes a chain of exact essays by means of social scientists and arts students who've studied nanotechnology and society from diverse perspectives

    Assessing how "ordinary" humans shape evaluations approximately new applied sciences and their adoption, this e-book addresses the function of media messages and pre-existing values during this strategy, in addition to how hazards can turn into both amplified or weakened alongside the way in which due to social mechanisms. utilizing good thought and examine to again awarded suggestions on threat notion and conversation, the writer discusses the possibility of utilizing expert consent, labels, and different sorts of purchaser warnings that experience proved to be potent in components except nano.

    An in-depth research into the concept that of mass communique practices, this publication explores the anomaly of why, regardless of its allure and promise, public engagement has had purely constrained luck within the discussion on nanotechnology. aimed toward discovering ideas, the book’s ensuing conclusions are thought of within the context of broader matters. those comprise how society makes up its collective brain approximately expertise adoption and all of the profound questions this increases, when it comes to democratic theory.

  • Download Interface by Branden Hookway PDF

    By Branden Hookway

    During this booklet, Branden Hookway considers the interface now not as know-how yet as a sort of dating with expertise. The interface, Hookway proposes, is immediately ubiquitous and hidden from view. it's either the bottleneck in which our courting to know-how needs to go and a efficient come upon embedded in the use of know-how. it's a website of contestation -- among human and laptop, among the cloth and the social, among the political and the technological -- that either defines and elides alterations. A virtuoso in a number of disciplines, Hookway bargains a concept of the interface that attracts on cultural idea, political idea, philosophy, artwork, structure, new media, and the historical past of technology and know-how. He argues that the theoretical mechanism of the interface bargains a strong method of questions of the human dating to expertise. Hookway reveals the beginning of the time period interface in nineteenth-century fluid dynamics and strains its migration to thermodynamics, info conception, and cybernetics. He discusses problems with topic formation, supplier, strength, and keep watch over, inside of contexts that come with know-how, politics, and the social function of video games. He considers the technological augmentation of people and the human-machine approach, discussing notions of embodied intelligence. Hookway perspectives the determine of the topic as either receiver and energetic manufacturer in procedures of subjectification. The interface, he argues, stands in a relation either alien and intimate, vertiginous and orienting to people who move its threshold.
