Quality guarantee for tomographic images developed

CWI researcher Wagner Fortes has developed new methods to determine the quality of tomographic images. Tomography is an imaging technique used in for instance medical CT scanners and electron microscopes that uses penetrating beams to record a series of two-dimensional images from a range of angles.

Kees Oosterlee new editor-in-chief of Journal of Computational Finance

Kees Oosterlee is the new Editor-in-Chief of The Journal of Computational Finance. This international refereed journal focuses on the advances in numerical and computational techniques in pricing, hedging and risk management of financial instruments. Oosterlee will be taking responsibility of selecting papers for the journal from the Fall 2013 issue and onwards.

Solar cells imaged at the nanoscale in 3D

Researchers of Centrum Wiskunde & Informatica (CWI) in Amsterdam succeeded in imaging the three-dimensional structure of solar cells with unprecedented accuracy. The results of this joint research with colleagues from the University of California in Davis and the Pacific Northwest National Laboratory are published today in the journal Advanced Functional Materials.

Seven greatest math puzzles on Radio 1

CWI's Barry Koren wrote, together with three co-authors, a book on the seven greatest puzzles in mathematics - called  “De zeven grootste raadsels van de wiskunde” - 'solve them and you will be a millionaire'.

Jeroen Hazewinkel wins prize for best presentation

At the annual meeting of the J.M. Burgers Centrum (the Research School for Fluid Dynamics) Jeroen Hazewinkel of the Centrum Wiskunde & Informatica (CWI) has been awarded the first prize for his presentation about tomographical (3D) reconstructions of internal water waves.

Mathematics for Dry Feet

On September 1st Joris Bierkens joined the Center of Mathematics & Computer Science (CWI) as an assistant in the Deltares funded project 'Mathematics for Dike Height Control'.

Jeroen Wackers wins Best PhD Thesis of 2007

CWI and BRICKS (Basic Research in Informatics for Creating the Knowledge Society) are proud to announce that Jeroen Wackers is a winner of the ECCOMAS Award for the Best PhD Thesis in 2007. The European Community on Computational Methods in Applied Sciences (ECCOMAS) issued the sixth edition of the Award to distinguish young scientists who have recently completed a PhD thesis in the field of Computational Methods in Applied Sciences and Engineering. The meaning of the Award is to highlight outstanding achievements of two young persons at the start of their scientific careers.

Barry Koren appointed professor of Numerical Mathematics

On 1 March 2008 Barry Koren was appointed professor of Numerical Mathematics at Leiden University. He will combine this position with his work at CWI as head of the research group Scientific Computing and Control Theory, and temporarily still with his work as professor of Computational Fluid Dynamics at TU Delft.

Amsterdam scientists in Nature: Global warming could destabilize plankton

Global warming of the surface layers of the oceans reduces the upward transport of nutrients. This generates chaos among the plankton, according to researchers of the University of Amsterdam (UvA), the Centrum voor Wiskunde en Informatica (CWI), and the University of Hawaii (USA). In Nature of 19 January 2006 they present advanced computer simulations, which predict that plankton growth will show strong fluctuations when the supply of nutrients is reduced. This prediction was rather unexpected: It contradicts the idea that deep plankton would represent a very stable system.

VIDI grant for Mark Peletier

The Netherlands Organization for Scientific Research (NWO) has awarded a VIDI grant to CWI researcher Mark Peletier for his mathematical research of the aggregation of molecules. Particular molecules form flat or stringlike structures, instead of shapeless lumps. Lipid molecules for example, aggregate in this way to form cell membranes. These structures are essential to the way living cells function.

CWI graduate Jeroen Wackers receives award

The faculty of Aerospace Engineering of Delft University of Technology has elected Jeroen Wackers as the best graduate student of the year 2002-2003. Wackers completed his graduation work in cooperation with the Computing and Control group (MAS2) of CWI. His grade average exceeded 9 of 10. With his thesis on the solution of 2D unsteady Euler equations he graduated with honour. Wackers will continue to work at CWI as an OIO studying the simulation of water-air flows. It is not the first time a MAS2-graduate receives praise.

Mathematics of influenza

CWI contributes to the largest influenza survey ever conducted in the Netherlands and Flanders. The Grote Griepmeting, organized by science website Kennislink, magazine Natuurwetenschap & Techniek and several research centres, maps the spread of influenza and common cold from November 1, 2003 until April 1, 2004. People are invited to contribute to the survey by signing up on the Grote Griepmeting website . On a regular basis they will be asked to report any symptoms like fever, a sore throat or a runny nose.
