We have obtained∼ 100 pc resolution CO and ∼ 60 pc resolution Hα observations of the dwarf spiral galaxy NGC 4605. We use them to derive a high resolution rotation curve and study the central density profile of NGC 4605’s dark matter halo. We find that these observations do not agree with the predictions of most high resolution Cold Dark Matter calculations. We investigate two extreme cases: 1)...

Multiple-view feature modelling is used in concurrent engineering. A shortcoming of current implementations is that they can only support low-level geometry-based product development phases, because they use form feature models. In order to overcome this shortcoming, we will use enhanced feature models, which are built from features that are defined as an aspect of a product that has some funct...

In Ontology-Based Data Access (OBDA), queries are posed over a high-level conceptual view, and then translated into queries over a potentially very large (usually relational) data source. The ontology is connected to the data sources through a declarative specification given in terms of mappings. Although prototype OBDA systems providing the ability to answer SPARQL queries over the ontology ar...

Model surface brightness profiles based on Fokker-Planck simulations have been used to assess the high resolution surface brightness profile of the globular cluster NGC 6397 of Lauzeral et al. (1992). The profile is well fitted by the model in the maximumexpansion phase of a gravothermal oscillation with a core radius of 0.06 pc (6), but an unresolved core cannot be ruled out. A core this size ...
