In this paper, a group acceptance sampling plan is developed for a multiple number of items to be tested simultaneously in a tester. This study provides information for the group acceptance sampling plan using the total number of failures under the truncated life test to establish the percentile life quality assuming that the product lifetimes are Birnbaum-Saunders distributed. The required num...

Analysis of dynamical interactions between distributed brain areas is of fundamental importance for understanding cognitive information processing. However, estimating dynamic causal interactions between brain regions using functional magnetic resonance imaging (fMRI) poses several unique challenges. For one, fMRI measures Blood Oxygenation Level Dependent (BOLD) signals, rather than the underl...

The non-functional QoS (quality of service) information helps us to select a proper Web-service from the web applications, by using component services such as UDDI[1](Universal Description, Discovery, and Integration) and MDS(Monitoring and Discovery System). MDS is a suite of web services to monitor and discover resources and service on Grids, but MDS only based on function aspects. This paper...
