Autonomic Adaptation of Virtual Distributed Environments in a Multi-Domain Infrastructure
Online Presentations | 11 Jul 2006 | Contributor(s):: Ryan Riley, Dongyan Xu
By federating resources from multiple domains, a shared infrastructure provides aggregated computation resources to a large number of users. With rapid advances in virtualization technologies, we propose the concept of virtual distributed environments as a new sharing paradigm for a multi-domain...

History of Semiconductor Engineering
Online Presentations | 28 Jun 2006 | Contributor(s):: Bo Lojek
When basic researchers started working on semiconductors during the late nineteen thirties and on integrated circuits at the end of the nineteen fifties, they did not know that their work would change the lives of future generations. Very few people at that time recognized the significance of...
