Improved Strategies for Distance Based Clustering of Objects on Subsets of Attributes in High-Dimensional Data
This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

Venus
Venus is de tweede planeet vanaf de zon en staat op 108 miljoen kilometer. Een jaar op Venus is korter dan op aarde en duurt maar 225 dagen. Doordat Venus heel langzaam om haar as draait, duurt een dag juist langer, wel 117 aarddagen! Op Venus is je alien dus elke twee dagen jarig.

Designing 'context-specific' regional innovation policy: a study on the role of regional government in six European regions
Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…
