Available in PDF, EPUB and Kindle. Book excerpt: LES SOURCES D'IONS MULTICHARGES DE TYPE EBIS FONCTIONNANT A L'HEURE ACTUELLE FONT TOUTES APPEL AUX TECHNIQUES CRYOGENIQUES POUR DES RAISONS DE POMPAGE ET DE COMPRESSION MAGNETIQUE; LES COUTS DE FABRICATION ET D'UTILISATION SONT PAR CONSEQUENT RELATIVEMENT ELEVES. IL EXISTE NEANMOINS UN DOMAINE OU LES SOURCES DE TYPE EBIS PEUVENT SE PASSER DES TECHNIQUES CRYOGENIQUES, CELUI DES FAIBLES FACTEURS DE COMPRESSION ET FORTS COURANTS. DANS CETTE OPTIQUE, UNE SOURCE BAPTISEE MICRO-EBIT, DERIVEE D'UN KLYSTRON AMPLIFICATEUR, A ETE CONCUE ET REALISEE AFIN DE VERIFIER S'IL EST POSSIBLE DE PRODUIRE DES IONS MULTICHARGES AVEC LES PARAMERES DEFINIS CI-DESSUS. CETTE SOURCE NE DISPOSE PAS DE SYSTEME D'EXTRACTION; LES IONS SONT DETECTES IN SITU PAR L'INTERMEDIAIRE DES RAYONS X EMIS LORS DE LEURS INTERACTIONS AVEC LE FAISCEAU ELECTRONIQUE. APRES UN INVENTAIRE DES SOURCES EBIS ET EBIT FONCTIONNANT DANS LE MONDE, NOUS DECRIVONS LA PHYSIQUE ET LA TECHNOLOGIE DE CE TYPE DE SOURCE, DONT LE PRINCIPE DE FONCTIONNEMENT REPOSE SUR L'IONISATION PAS-A-PAS D'IONS PIEGES PAR LA CHARGE D'ESPACE DU FAISCEAU ELECTRONIQUE. DANS UNE SECONDE PARTIE, NOUS DECRIVONS LE DISPOSITIF MICRO-EBIT, DE SA CONCEPTION AUX PREMIERS ESSAIS DE TRANSPORT DE FAISCEAU. LES PERFORMANCES PREVUES DE LA SOURCE PAR DES SIMULATIONS NUMERIQUES ET DES ESSAIS DE VIDE SONT PRECISEES: DENSITE DE COURANT DE L'ORDRE DE 100 A/CM#2 POUR UN FAISCEAU DE 1 AMPERE-10 KEV SE PROPAGEANT DANS UN VIDE DE L'ORDRE DE 1.10##1#0 MBAR, TEMPS DE CONFINEMENT DE 1 SECONDE POUR PRODUIRE DE L'ARGON HELIUMOIDE. LA DERNIERE PARTIE EST CONSACREE AUX RESULTATS EXPERIMENTAUX QUI SONT ANALYSES APRES DESCRIPTION DES DIAGNOSTICS AUX RAYONS X QUI ONT ETE EMPLOYES. LA SOURCE MICRO-EBIT A PERMIS DE PRODUIRE DIVERS IONS, DONT DE L'ARGON 16+, AVEC LE TEMPS DE CONFINEMENT PREVU

Download or read book The Art of Noise written by Francesco Balilla Pratella and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The music and noise manifestos of the Italian Futurists formed a blueprint for sonic warfare waged against traditionalism, a radical new agenda played out with machines primed for maximal acoustic destruction and aimed at the negation of all existing value systems. THEe ^ARTe ^OFe ^NOISE collects together these and other writings for the first time in English, showing how the origins of modern noise music actually date from a century ago, forming an invaluable insight into Futurist thought and its most enduring and relevant legacies, and revealing how an understanding of noise-art is key to a complete comprehension of Futurist painting. THEe ^ARTe ^OFe ^NOISE includes five key Futurist manifestos: Luigi Russolo's "The Art of Noises" and "The Futurist Noise Machines", and Francesco Balilla Pratella's "Manifesto of Futurist Musicians", "Technical Manifesto of Futurist Music", and "Destruction of Quadrature"; plus Carlo Carra 's related sensory manifesto "The Painting of Sounds, Noises and Smells"; Bruno Corra's notes on "Chromatic Music"; proto-Futurist Ferrucchio Busoni's visionary and influential "Sketch for a New Aesthetic of Sound Art"; a historical introduction on Futurist music and its legacy; and a chronology of Futurist music and noise.

Book excerpt: "In a remarkable career spanning more than six decades, Philip W. Anderson has made many fundamental contributions to physics. As codified in his oft-quoted phrase "More is Different", Anderson has been the most forceful and persuasive proponent of the radical, but now ubiquitous, viewpoint of emergent phenomena: truly fundamental concepts that can and do emerge from studies of Nature at each layer of complexity or energy scale. Anderson's ideas have also extended deeply into other areas of physics, including the Anderson-Higgs mechanism and the dynamics of pulsars. PWA90: A Lifetime of Emergence is a volume of original scientific essays and personal reminiscences of Philip W Anderson by experts in the field, that were presented as part of "PWA90: Emergent Frontiers of Condensed Matter" meeting held at Princeton in December 2013 to highlight Anderson's contributions to physics"--

Download or read book Hayek Currency Competition and European Monetary Union written by Otmar Issing and published by . This book was released on 2000 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1999 IEA Hayek Memorial Lecture, reprinted in Occasional Paper 111, Otmar Issing, the eminent monetary economist and one of Europe's most influential central bankers, discusses currency competition and European Monetary Union. Professor Issing argues that choosing a '..Hayekian discovery process as a route to monetary union' would have been too risky. However, the introduction of the euro has triggered '..a kind of Hayekian discovery process' which gives more scope for the private sector to 'enhance the quality of the medium-of-exchange and store-of-value functions of money.' This Occasional Paper also includes commentaries by two other distinguished economists - Professors Lawrence H. White and Roland Vaubel - who criticise Professor Issing's views. There is then an Afterword by Issing.

Available in PDF, EPUB and Kindle. Book excerpt: Colonial governing in Northern Nigeria has not been without emotions, tensions and struggles. Conflicts and misunderstandings plagues the foreign rulers themselves and their African employees, in dealing with the African Studies. The British political officers on the ground did their best at work but they were sometimes frustrated by their African political agents and local rulers. Yet, the political officers knew moments of joy, as much as the political agents. This monograph is instructive on emotions and their management at the workplace in Northern Nigeria.
