We consider the construction of geometric integrators in the class of RKMK methods. Any di erential equation in the form of an in nitesimal generator on a homogeneous space is shown to be locally equivalent to a di erential equation on the Lie algebra corresponding to the Lie group acting on the homogenous space. This way we obtain a distinction between the coordinate-free phrasing of the di er...

Integration of various ®ngerprint matching algorithms is a viable method to improve the performance of a ®ngerprint veri®cation system. Di€erent ®ngerprint matching algorithms are often based on di€erent representations of the input ®ngerprints and hence complement each other. We use the logistic transform to integrate the output scores from three di€erent ®ngerprint matching algorithms. Experi...

Three di erent algorithms for the generation of stationary Gaussian time series with given autocorrelation function are presented in this paper. The algorithms have already been suggested in the literature but are not well known and have never been compared before. Interrelations between the di erent methods, advantages and disadvantages with respect to speed and memory requirements and the ran...
