The Web is the most pervasive collaborative technology in widespread use today; and its use to support eLearning has been highly successful. There are many web-based Virtual Learning Environments such as WebCT, FirstClass, and BlackBoard as well as associated web-based Managed Learning Environments. In the future, the Grid promises to provide an extremely(More)
There has been a long history of CASE tool development, with an underlying software repository at the heart of most systems. Usually such tools, even the more recently web-based systems, are focused on supporting individual projects within an enterprise or across a number of distributed sites. Little support for maintaining large heterogeneous collections(More)
Collaboration by use of common artifacts is at the core of e-science. A recent enabling technology is the Grid, which ties together heterogeneous computation and data resources through the use of middleware, linking the techniques and resources to infer higher-level knowledge. This article presents results from research and development of Grid technology(More)
We describe the construction of an ultra-high vacuum (UHV) chamber and a radio frequency helical resonator for use in co-trapping atomic and molecular ions. Cleaning procedures for the in-vacuum components are provided. These procedures give positive results in cleaning copper electrodes. The thesis also provides general UHV construction techniques and(More)
This paper describes an environment that allows a development team to share knowledge about software artefacts by recording decisions and rationales as well as supporting the team in formulating and maintaining design constraints. It explores the use of multi-dimensional design spaces for capturing various issues arising during development and presenting(More)
