Efficient Approximation Algorithms for Repairing Inconsistent Databases
We consider the problem of repairing a database that is inconsistent wrt a set of integrity constraints by updating numerical values. In particular, we concentrate on denial integ...

Computing longest duration flocks in trajectory data
Moving point object data can be analyzed through the discovery of patterns. We consider the computational efficiency of computing two of the most basic spatio-temporal patterns in...

Approximation of protein structure for fast similarity measures
It is shown that structural similarity between proteins can be decided well with much less information than what is used in common similarity measures. The full C representation c...
