Book Mod  lisation et Optimisation d un G  n  rateur Synchrone    Double Excitation de Forte Puissance

Download or read book Mod lisation et Optimisation d un G n rateur Synchrone Double Excitation de Forte Puissance written by Aymen Ammar and published by . This book was released on 2013 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alliant flexibilité de contrôle et bon rendement, les Machines Synchrone à Double Excitation (MSDE) sont de plus en plus investiguées pour diverses applications de petites et moyennes puissances et rarement pour des applications de fortes puissances. Cette thèse a pour objectif l'étude d'un Générateur Synchrone à Double Excitation (GSDE) de forte puissance. Un modèle de comportement a été établi. Des méthodes analytiques et semi-analytiques ont été utilisées pour la modélisation multi-physique de la machine. Ce modèle a été validé, dans un premier temps, par comparaison aux résultats d'un modèle éléments finis.Comparé à un Générateur Synchrone à Pôles Saillants (GSPS), le GSDE offre des solutions plus intéressantes énergétiquement et économiquement, que ce soit en fonctionnement à vitesse constante ou à vitesse variable. Dans le cadre d'un fonctionnement en générateur éolien, l'augmentation du nombre d'encoche par pôle et par phase et l'augmentation de la fréquence d'alimentation contribuent à l'amélioration des performances de la GSDE. Cependant il faudrait tenir compte des impacts sur l'électronique de puissance et le multiplicateur mécanique. En plus, la distribution de Weibull et le bon choix de la plage utile de variation de la vitesse du vent, jouent un rôle important sur le dimensionnement optimal du générateur éolien.Un prototype de GSDE d'une puissance d'1MVA a été dimensionné, optimisé et fabriqué. Tout d'abord, le prototype a servi à la validation du modèle multi-physique. En plus la réalisation des essais sur deux étapes (avant et après le collage des aimants permanents) a montré l'apport énergétique du GSDE par rapport au GSPS.

  • Author : Jeffrey S. Siker
  • Publisher : Fortress Press
  • Release : 2017-09-01
  • ISBN : 1506407870
  • Pages : 317 pages

Download or read book Liquid Scripture written by Jeffrey S. Siker and published by Fortress Press. This book was released on 2017-09-01 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electronic Bible is here to stay‒‒packaged in software on personal computers, available as apps on tablets and cell phones. Increasingly, students look at glowing screens to consult the Bible in class, and congregants do the same in Bible study and worship. Jeffrey S. Siker asks, what difference does it make to our experience of Scripture if we no longer hold a book in our hands, if we again “scroll” through Scripture? How does the “flow” of electronic Scripture change our perception of the Bible’s authority and significance? Siker discusses the difference made when early Christians adopted the codex rather than the scroll and Gutenberg began the mass production of printed Bibles. He also reviews the latest research on how the reading brain processes digital texts and how churches use digital Bibles, including American Bible Society research and his own surveys of church leaders. Siker asks, does the proliferation of electronic translations reduce the perceived seriousness of Scripture? Does it promote an individualistic response to the Bible? How does the change from a physical Bible affect liturgical practice? His synthesis of the advantages and risks of the digitized Bible merit serious reflection in classrooms and churches alike.

Book Creating Church Online

Download or read book Creating Church Online written by Tim Hutchings and published by Routledge. This book was released on 2017-04-21 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Online churches are internet-based Christian communities, pursuing worship, discussion, friendship, support, proselytization, and other key religious goals through computer-mediated communication. Hundreds of thousands of people are now involved with online congregations, generating new kinds of ritual, leadership, and community and new networks of global influence. Creating Church Online constructs a rich ethnographic account of the diverse cultures of online churches, from virtual worlds to video streams. This book also outlines the history of online churchgoing, from its origins in the 1980s to the present day, and traces the major themes of academic and Christian debate around this topic. Applying some of the leading current theories in the study of religion, media and culture to this data, Tim Hutchings proposes a new model of religious design in contexts of mediatization, and draws attention to digital networks, transformative third spaces and terrains of existential vulnerability. Creating Church Online advances our understanding of the significance and impact of digital media in the religious and social lives of its users, in search of new theoretical frameworks for digital religion.

Book Computation and the Humanities

Download or read book Computation and the Humanities written by Julianne Nyhan and published by Springer. This book was released on 2016-11-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the application of computing to cultural heritage and the discipline of Digital Humanities that formed around it. Digital Humanities research is transforming how the Human record can be transmitted, shaped, understood, questioned and imagined and it has been ongoing for more than 70 years. However, we have no comprehensive histories of its research trajectory or its disciplinary development. The authors make a first contribution towards remedying this by uncovering, documenting, and analysing a number of the social, intellectual and creative processes that helped to shape this research from the 1950s until the present day. By taking an oral history approach, this book explores questions like, among others, researchers’ earliest memories of encountering computers and the factors that subsequently prompted them to use the computer in Humanities research. Computation and the Humanities will be an essential read for cultural and computing historians, digital humanists and those interested in developments like the digitisation of cultural heritage and artefacts.

Book Ancient Worlds in Digital Culture

Download or read book Ancient Worlds in Digital Culture written by Claire Clivaz and published by BRILL. This book was released on 2016-08-15 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume presents a selection of research projects in Digital Humanities applied to the “Biblical Studies” in the widest sense and context, including Early Jewish and Christian studies, hence the title “Ancient Worlds”. Taken as a whole, the volume explores the emergent Digital Culture at the beginning of the 21st century. It also offers many examples which attest to a change of paradigm in the textual scholarship of “Ancient Worlds”: categories are reshaped; textuality is (re-) investigated according to its relationships with orality and visualization; methods, approaches and practices are no longer a fixed conglomeration but are mobilized according to their contexts and newly available digital tools.

Book Networked Theology  Engaging Culture

Download or read book Networked Theology Engaging Culture written by Heidi A. Campbell and published by Baker Academic. This book was released on 2016-09-20 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Theological Implications of Digital Culture This informed theology of communication and media analyzes how we consume new media and technologies and discusses the impact on our social and religious lives. Combining expertise in religion online, theology, and technology, the authors synthesize scholarly work on religion and the internet for a nonspecialist audience. They show that both media studies and theology offer important resources for helping Christians engage in a thoughtful and faith-based critical evaluation of the effect of new media technologies on society, our lives, and the church.

Book Paper Machine

    Book Details:
  • Author : Jacques Derrida
  • Publisher : Stanford University Press
  • Release : 2005
  • ISBN : 9780804746205
  • Pages : 228 pages

Download or read book Paper Machine written by Jacques Derrida and published by Stanford University Press. This book was released on 2005 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book questions the book itself, archivization, machines for writing, and the mechanicity inherent in language, the media, and intellectuals. Derrida questions what takes place between the paper and the machine inscribing it. He examines what becomes of the archive when the world of paper is subsumed in new machines for virtualization, and whether there can be a virtual event or a virtual archive. Derrida continues his long-standing investigation of these issues, and ties them into the new themes that governed his teaching and thinking in the past few years: the secret, pardon, perjury, state sovereignty, hospitality, the university, animal rights, capital punishment, the question of what sort of mediatized world is replacing the print epoch, and the question of the “wholly other.” Derrida is remarkable at making seemingly occasional pieces into part of a complexly interconnected trajectory of thought.

Book The Confession of Augustine

Download or read book The Confession of Augustine written by Jean-François Lyotard and published by Stanford University Press. This book was released on 2000 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lyotard approaches his subject by returning to his earliest phenomenological training, rearticulating Augustine's sensory universe from a vantage point imaginarily inside the confessant's world, a vantage point that reveals the intense point of conjuncture between the sensual and the spiritual, the erotic world and the mystical, being and appearance, sin and salvation. Lyotard reveals the very origins of phenomenology in Augustine's narrative, and in so doing also shows the origins of semiotics to lie there (in the explication of the Augustinian heavens as skin, as veil, as vellum).
