Available in PDF, EPUB and Kindle. Book excerpt: Les travaux présentés dans ce mémoire concernent la définition d'un nouveau type de réacteur susceptible de favoriser le transfert de matière entre deux phases fluides notamment gaz/liquide considéré comme l'une des étapes clé du processus d'oxydation appliqué au traitement des effluents industriels non biodégradables. L'étude expérimentale a été abordée par les tests hydrodynamiques permettant d'estimer la rétention gazeuse et de transfert à travers l'ozonation d'une solution synthétique d'acide tannique dans un réacteur à deux impacts. Neuf réacteurs de différentes configurations ont été construits afin d'apprécier l'influence de la géométrie sur l'efficacité de ce système. L'étude a montré que la taille du réacteur reste sans influence significative. La comparaison de ce réacteur avec un réacteur fonctionnant à quatre impacts souligne l'importance du phénomène d'impact dans le processus de transfert de matière. Un nouveau réacteur dit à impacts muldirectionnel a été défini. La multiplication des impacts de différentes natures par déviation tangentielle sur un cylindre situé au centre de la zone d'impact crée une très forte zone de turbulence très favorable à l'oxydation. L'étude hydrodynamique et de transfert de matière dans ce système montre son efficacité très supérieure aux systèmes les plus utilisés actuellement.

Book Synopsis Transforming Computer Technology by : Arthur L. Norberg
Download or read book Transforming Computer Technology written by Arthur L. Norberg and published by Johns Hopkins University Press. This book was released on 2000-02-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Association of American Publishers Professional and Scholarly Publishing Award for Computer Science Over the course of several decades, the Pentagon's Information Processing Techniques Office (IPTO) helped transform computing from a cumbersome enterprise based on batch processing to the instantly interactive, graphically rich, highly intelligent computing of today. With the purpose of improving command and control systems for the military, IPTO researchers strengthened time-sharing, laid the groundwork for graphics and parallel processing, contributed to the study of artificial intelligence, and developed the wide-area network that came to be known as the Internet. Transforming Computer Technology examines these and other developments at the Defense Department's Advanced Research Projects Agency in its heyday between 1962 and 1986. The authors show how Pentagon programs affected significant developments in both computer science and engineering. They analyze the management of the office, the origins and growth of important IPTO programs, and the interaction of the staff with the R & D community. They pay special attention to IPTO's role in executing research at the leading edge of computing and networking and in working with the military to transfer that research into practical use. And they show how, by the 1990s, the research results had been assimilated into systems both for the military and for civilian society.
