Available in PDF, EPUB and Kindle. Book excerpt: Le developpement ou l'amelioration des nouvelles filieres de transistors a effet de champ hyperfrequences ne peut s'envisager sans l'appui de la modelisation physique qui permet la predetermination des caracteristiques et l'optimisation des structures. Le travail que nous presentons a pour objet l'elaboration d'un modele physique quasi bidimensionnel capable de traiter des regimes specifiques tels que le claquage par avalanche ou l'etude de circuits en regime temporel. Dans la premiere partie, les differents types de composants susceptibles d'etre utilises pour l'amplification de puissance hyperfrequence sont presentes. Dans chacun des cas, l'accent est porte sur les principales limitations rencontrees dans ce type d'application. Les differents outils de simulation physique sont ensuite presentes afin de mettre en evidence les avantages lies au modele quasi bidimensionnel que nous avons utilise. Dans la partie suivante, nous decrivons la methodologie mise en oeuvre pour l'etude du claquage par avalanche, un des phenomenes les plus limitatifs pour l'amplification de puissance hyperfrequence. L'influence des principaux parametres technologiques (longueur de grille, geometrie du recess, caracteristiques de l'epitaxie) est envisagee. La validation des resultats est obtenue en les comparant a ceux issus d'autres modeles physiques ou a des mesures impulsionnelles. Le modele mis au point peut facilement etre adapte a l'etude de composants de filieres differentes. Enfin, la derniere partie de ce travail est consacree au couplage d'un nouveau modele physique de transistor a effet de champ avec un modele de circuit permettant une analyse en regime temporel. Apres la description du modele que nous avons elabore, sa mise en oeuvre est presentee en traitant differents types de dispositifs.

Edited by two outstanding scholars in the field, W. J. T. Mitchell and Mark B. N. Hansen, the volume features works by a team of distinguished contributors. These essays, commissioned expressly for this volume, are organized into three interrelated groups: “Aesthetics” engages with terms that describe sensory experiences and judgments, “Technology” offers entry into a broad array of technological concepts, and “Society” opens up language describing the systems that allow a medium to function. A compelling reference work for the twenty-first century and the media that form our experience within it, Critical Terms for Media Studies will engage and deepen any reader’s knowledge of one of our most important new fields.

Download or read book Crypto Anarchy Cyberstates and Pirate Utopias written by Peter Ludlow and published by MIT Press. This book was released on 2001-05-25 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide-ranging collection of writings on emerging political structures in cyberspace. In Crypto Anarchy, Cyberstates, and Pirate Utopias, Peter Ludlow extends the approach he used so successfully in High Noon on the Electronic Frontier, offering a collection of writings that reflects the eclectic nature of the online world, as well as its tremendous energy and creativity. This time the subject is the emergence of governance structures within online communities and the visions of political sovereignty shaping some of those communities. Ludlow views virtual communities as laboratories for conducting experiments in the construction of new societies and governance structures. While many online experiments will fail, Ludlow argues that given the synergy of the online world, new and superior governance structures may emerge. Indeed, utopian visions are not out of place, provided that we understand the new utopias to be fleeting localized "islands in the Net" and not permanent institutions. The book is organized in five sections. The first section considers the sovereignty of the Internet. The second section asks how widespread access to resources such as Pretty Good Privacy and anonymous remailers allows the possibility of "Crypto Anarchy"—essentially carving out space for activities that lie outside the purview of nation states and other traditional powers. The third section shows how the growth of e-commerce is raising questions of legal jurisdiction and taxation for which the geographic boundaries of nation-states are obsolete. The fourth section looks at specific experimental governance structures evolved by online communities. The fifth section considers utopian and anti-utopian visions for cyberspace.

Download or read book Industry 4 0 for SMEs written by Dominik T. Matt and published by Springer Nature. This book was released on 2020-01-03 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book explores the concept of Industry 4.0, which presents a considerable challenge for the production and service sectors. While digitization initiatives are usually integrated into the central corporate strategy of larger companies, smaller firms often have problems putting Industry 4.0 paradigms into practice. Small and medium-sized enterprises (SMEs) possess neither the human nor financial resources to systematically investigate the potential and risks of introducing Industry 4.0. Addressing this obstacle, the international team of authors focuses on the development of smart manufacturing concepts, logistics solutions and managerial models specifically for SMEs. Aiming to provide methodological frameworks and pilot solutions for SMEs during their digital transformation, this innovative and timely book will be of great use to scholars researching technology management, digitization and small business, as well as practitioners within manufacturing companies.
