In this paper, we have made an attempt to take a look under the hood of Spotlight and understand some of the following questions amongst others: • How well-integrated is Spotlight with the file system? • How reliable is the interface between Spotlight and the file system? • Is live update a myth or a reality under heavy file system activity? Based on our experiments, it seems that Spotlight is ...

Enterprise-wide, web-based systems can be assisted in their construction by the use of agents and an agentoriented methodology. As part of an extensive research programme to create such an AO methodology by combining the benefits of method engineering and existing object-oriented frameworks (notably the OPF), we have analysed here contributions to the OPF repository of process components from t...

In this paper we investigate weak contact relations C on a lattice L, in particular, the relation between various axioms for contact, and their connection to the algebraic structure of the lattice. Furthermore, we will study a notion of orthogonality which is motivated by a weak contact relation in an inner product space. Although this is clearly a spatial application, we will show that, in cas...

The growth of internet and the evolution of supporting infrastructures motivated universities and other educational institutions to adopt new teaching methods. These unsupervised methods are focused on the dissemination of the educational material and the evaluation of the users through tests and activities. The user behavior is not monitored and the performance of users cannot be reasoned in m...
