This document outlines consequently the fundamental concept of a Mobile Grid as understood by Akogrimo, introduces the fundamental concept such as the Base and Operative Virtual Organizations and outlines the major building blocks. A special focus is given on security considerations and the document ends with a list of documents recommended for further reading. The Akogrimo Mobile Grid Referenc...

The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamental plane ellipticals in general, cluster populations evolve more rapidly in smaller galaxies because of the higher mass density. A simple evolutionary model reproduces the observed trend in specific frequency with lu...

XML has become an emerging standard for data representation and data exchange on the Web. Although XML data is self-describing, most application domains tend to use document schemas. Over a period of time, these schemas need to be modified to reflect a change in the real-world, a change in the user’s requirements, mistakes or missing information in the initial design. Most of the current XML ma...

Abstract Document collections evolve over time, new topics emerge and old ones decline. At the same time, the terminology evolves as well. Much literature is devoted to topic evolution in nite document sequences assuming a xed vocabulary. In this study, we propose \Topic Monitor" for the monitoring and understanding of topic and vocabulary evolution over an in nite document sequence, i.e. a str...
