The distribution of center self-embeddings and extrapositions in German is assumed to reflect a universal performance strategy of minimizing memory load during parsing. Self-embedded relative clauses of embedding depth 2 were semi-automatically analysed in a treebank of German newspaper texts. Clause length and especially extraposition distance are found as the main distinctive parameters betwe...

Fractal image compression is based on the rather poorly motivated assumption that “natural” images exhibit significant affine self-similarity. The accuracy of this assumption is evaluated by a comparison between the statistics of natural images and those of a multiresolution stochastic model designed to generate images exhibiting affine self-similarity as assumed by fractal coding techniques. T...
