Design techniques in the layout that contribute to greater yield will not likely be on their radar screen as their focus will be...

1 Performance Evaluation of IEC 61850 Process

The paper presents the performance of a novel distributed bus differential protection scheme, which utilizes independent multi-principle advanced protection algorithms, including differential percent slope, delta phase directional comparison, rate of change of differential (ROCOD) currents, delta phase directional comparison on neutral current differential, and a check zone to secure the electr...

Development of a Multimedia Archiving Teleservice Using the DFR Standard

In this paper, we describe the development of an archiving system according to the BERKOM teleservice ‘‘Multimedia Archiving” defined recently. This teleservice is utilized for storage and retrieval of multimedia documents. It can be exploited in applications that require document pools, information services, and workflow management. As a basis of our system we use the ISO/IEC standard ‘‘Docume...
