Current trends in computer science such as the semantic web, ubiquitous computing, and self-* systems make it increasingly important that programming technology suitable for open, unpredictable, dynamic environments are made available. Many abstractions and techniques that emerged from research in multi-agent systems can have major impact in the effectiveness of (the development of) such system...

Much of my research in computational linguistics has been bound up with two emerging strategies of the 1990’s: statistical optimality and phonological optimality. Statistics properly used can translate and enrich linguistic theories—rather than replacing them—and can connect those theories to processing models. That is, the statistical worldview need not be tied to simplistic engineering tricks...

Within the framework of a project comprising part of the Spanish Space Program related to the JASON-1 CNES (Centre National d’Etudes Spatiales)/NASA (National Aeronautics and Space Administration) mission, a campaign was conducted on June 9-17, 2003, in the Absolute Calibration Site of the island of Ibiza. The objective was to determine the local marine geoid slope under the ascending (187) and...

We provide a brief description of the Jason-DTU system, including the methodology, the tools and the team strategy that we plan to use in the agent contest. Updated 1 October 2010: Appendix with comments on the contest added.
