Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse concerne les écoulements de fluides à seuil de contrainte autour d'un obstacle cylindrique en milieu confiné avec une configuration d'écoulement de Poiseuille.Expérimentalement, un banc d'essai permettant d'obtenir un écoulement en continu dans un circuit fermé a été mis en place. Les régimes d'écoulement rampant, recirculant et instationnaire périodique ont été étudiés. De nouveaux résultats ont été obtenus avec un fluide newtonien et des solutions de Carbopol, polymère permettant de réaliser des fluides à seuil modèles utilisés en recherche et développement et dans l'industrie. Une caméra rapide et un éclairage plan laser a servi pour l'établissement d'images qui ont ensuite été traitées par PIV. Les champs de vitesses cinématiques, les morphologies d'écoulement et les paramètres critiques de transitions de régimes ont été déterminés.Numériquement, un modèle viscoplastique basé sur la loi de Herschel-Bulkley régularisée a été utilisé. Des résultats comme les morphologies d'écoulement, la localisation des zones rigides, les champs de vitesses ont été obtenus. Ceci a permis de comparer les différences entre les effets liés à la nature des gels de Carbopol et la modélisation viscoplastiques. Une étude spécifique sur le glissement à l'interface fluide-structure a également été réalisée avec l'utilisation d'un modèle de lubrification élasto-hydrodynamique.

Book excerpt: "Simon Denny's new body of work for Portikus ranks among the most ambitious the artist has developed to date. Over the period of one year, the artist researched and developed an intricate project that has grown to considerable dimensions -- both physically and in terms of its critical content. For two months, the monumental gallery space is turned into an homage to technology, communication, and the relentless need for innovation. Simon Denny has produced an embracing and multi-faceted installation that functions as a documentary of the South Korean technology giant Samsung and its global success story. The exhibition's title, "New Management", refers to the legendary management philosophy that Lee Kun-hee, Chairman of the Samsung Group, infamously introduced in the early nineties."--Publisher's website.

Available in PDF, EPUB and Kindle. Book excerpt: In Political Identity and Archaeology in Northeast Honduras, Thomas Cuddy fills a substantial void in the scholarship on the origins of complex societies and the Central American political landscape, drawing on previously unexamined research conducted by anthropologist William Duncan Strong during a 1933 expedition to find the southern reaches of Maya culture. From AD 200 until the Spanish conquests of the sixteenth and seventeenth centuries, the Pech chiefdoms of northeast Honduras maintained their autonomy through tactful engagement with the powerful states and empires of Mesoamerica and increasingly large societies like the Greater Nicoya region of Costa Rica. Cuddy, working with Strong's untapped fieldwork, examines symbolic expressions to reconstruct the dynamic contexts that structured power in Central American prehistory and shaped the political identity of northeast Honduras. By being similar to, but distinct from, their powerful neighbors, the polities of northeast Honduras created their own senses of power and identity that served their continued growth while states and empires crumbled around them. Political Identity and Archaeology in Northeast Honduras suggests new avenues for understanding the structure and administration of chiefdoms by revealing the archaeological resources and rich ethnohistoric context of the area and the compelling history of its early scholarly explorations.

Download or read book In the Flow written by Boris Groys and published by Verso Books. This book was released on 2016-02-16 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 20th century, art and its institutions came under critique from a new democratic and egalitarian spirit. In an age of secularism and materialism, artworks would be understood as merely things among other things. This meant an attack on the techniques of realism, and the traditional mission of the museum, both designed shield a small class of objects from the entropic fate awaiting everything else-and the development of an approach that Boris Groys calls "direct realism": an art that would not produce objects, but practices that could enter the flow of time to live and die like the rest of us. But for more than a century now, every advance in this direction has been quickly followed by new means of preserving art's distinction. In this major new work, Groys, one of the world's leading art theorists, charts the paradoxes produced by this tension, which continues to structure the production and reception of new art. The internet, the latest medium through which artists have attempted to disavow this special status, inverts the most notorious consequence of early modernist developments. If the techniques of mechanical reproduction gave us objects without aura, digital production generates aura without objects, transforming all its materials into vanishing markers of the transitory present.
Download or read book Wim Delvoye written by Wim Delvoye and published by Rectapublishers. This book was released on 2001 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Borrowing its name from the ancient sewer in Rome, Belgian conceptualist Wim Delvoye's new and improved "Cloaca" is a room-sized shit-making machine whose bowels process two meals a day, serving up a mouthful of complex themes: scatalogy and disgust, high and low culture, man as machine and vice-versa, and the inversion of art semiotics. Many of these same concerns are processed in Delvoye's other work, like the life-sized carved walnut replica of a cement truck, the wood cabinet stocked with 32 circular saw blades painted with scenes in Delft China blue, and a herd of pigs tatooed by Antwerp's finest needle-men. Feces and other anal subjects are parsed in accompanying essays by such luminaries as Milan Kundera, Gerardo Mosquera, Dan Cameron, Georges Bataille and Salvador Dali.
