Grid Resource Discovery Service is currently a very important focus of research. We propose a scheme that presents essential characteristics for efficient, self-configuring and fau...
In this paper, we design recommender systems for weblogs based on the link structure among them. We propose algorithms based on refined random walks and spectral methods. First, w...
Dynamic resource provisioning aims at maintaining the endto-end response time of a web application within a predefined SLA. Although the topic has been well studied for monolithi...
