## Abstract The edge detection problem in blurred and noisy 2βD signals is dealt with. An adaptive signal processing algorithm is proposed which marks edge points according to an hypothesis test which compares the likelihoods of two models describing the local signal behaviour in the two cases of a
A widely used approach for the computation of time-harmonic electromagnetic ΓΏelds is based on the wellknown double-curl equation for either E or H, where edge elements are an appealing choice for ΓΏnite element discretizations. Yet, the nullspace of the curl-operator comprises a considerable part of
## SUMMARY The solution of problems in computational fluid dynamics (CFD) represents a classical field for the application of advanced numerical methods. Many different approaches were developed over the years to address CFD applications. Good examples are finite volumes, finite differences (FD), a
