Amsterdam Researchers Win International Semantic Web Challenge

The MultimediaN E-culture Project has won the first prize at the Semantic Web Challenge at the 5th International Semantic Web Conference held in Athens, Georgia, USA. This international competition aims to advance our understanding of how explicit, machine processable descriptions of data can be exploited on the Web. To qualify, applications should integrate, combine, and deduce information from heterogeneous and distributed sources in an open environment to assist users in specific tasks, potentially unforeseen by the original authors of the underlying Web content.

New upper bounds for kissing in higher dimensions

Christine Bachoc (Université Bordeaux) and Frank Vallentin (Centrum voor Wiskunde en Informatica, Amsterdam), have found new upper bounds for 'kissing' in higher dimensions. In geometry the kissing number is the maximum number of non-overlapping unit balls that can simultaneously touch a central unit ball. In two dimensions the kissing number is six. You can clearly see this if you group euro coins around one central euro coin. The kissing number is only known for the dimensions 1, 2, 3, 4, 8 and 24.

Fokker F27 Friendship wins 2006 Best Dutch Design Election

The Fokker F27 Friendship won the Best Dutch Design Election on May 5 2006, organized by the Dutch newspaper NRC Handelsblad together with the Premsela Stichting. At the time, the Mathematisch Centrum - now CWI - made so-called flutter computations for the wings on one of the first computers in the Netherlands. Flutter is a vibration which can vary from a light 'buzz' to serious damage or destruction of the aircraft. With the computations the form of the wing could be adapted to minimize flutter. Over five thousand people chose the F27 design from 25 nominees.

Better train planning with mathematical models

Better planning for trains with mathematical models - this is the subject of the dissertation of Gabor Maroti of the Centrum voor Wiskunde en Informatica (CWI). Maroti studied several optimization models for tactical and operational planning and maintenance routing. He looked at efficiency, robustness (immunity for failures) and service level for clients - their chances to have a seat. With the models, NS can compare these aspects quantitatively and choose a good balance between them.
