PERSONAL INFORMATION - Previous Projects

The final MSc. project was carried at the group of Numerical Analysis in collobaration with Shell Rijswijk. The topic was the construction of combined preconditioners for the Helmholtz problem. More information about this project can be found here.

Another project during the studies was done in colloboration with DUT (Delft University of Technology), RIVM (National Institute for Public Health and the Environment) and KNMI (Royal Dutch Meteorological Institute) in 2003. The subject was detection on changes in climate extremes and weather-related indicators in The Netherlands, that was a statistical trend and uncertainty analysis using historical daily data of the period 1901-2003. These data of different weather indicators (such as temperature and precipitation) had been examined. Using statistical packages S-Plus and TrendSpotter which can determine trends and confidence intervals, some conclusions have been drawn with respect to these indicators. Main conclusions were that the temperature has increased significantly, while the annual precipitation remained constant. Another remarkable conclusion was that the chance of an 'Elfstedentocht' remained also constant in the last 100 years. Apparently, the greenhouse effect resulted in higher temperatures in summer but not in wintertime. The first 101 pages of the final thesis can be found here.
