Numerical Relativity (NR) uses advanced numerical techniques in supercomputers to simulate the relativistic, strong-field dynam s and radiation of merging compact binaries, such as black holes and neutron tars, and oth r s milar phenomena that are governed by E nstein's th ory of General R lativi y (GR). Analytical relativity (AR) metho s, based on Po -Newtonian exp ns ons of the GR qua ion nd ...

We study the problem of efficient deployment of software components in a service engineering context. Run-time manipulation, adaptation and composition of entities forming a distributed service is a multi-faceted problem challenged by a number of requirements. The methodology applied and presented can be viewed as an intersection between systems development and novel network management solution...

Electronic tables running single display groupware have good potential for enhancing face-to-face collaborations. Our goal is to understand how people collaborate over physical and electronic tables. We articulate the unique collaborative characteristics of tables, and describe our initial observations of people collaborating on a regular table, a table display, and a vertical display.

The goal of this paper is to construct an integrated approach to collaboration and conceptual change. To this end, a case of conceptual change is analyzed from the point of view of conversational interaction. It is proposed that the crux of collaboration is the problem of convergence: How can two (or more) people construct shared meanings for conversations, concepts, and experiences? Collaborat...

A system comprised of collaborating mobile clients and a server is introduced in order to solve known item search tasks. The clients query the server for small video sequences according to some search criteria and are kept informed about the actions of collaborating participants (viewed frames, queries submitted, bookmarks set). The results are browsed and refined through a GUI that takes advan...
