Impossible fractals
Impossible objects are a type of optical illusion involving ambiguous visual descriptions of figures that cannot physically exist. It is shown by way of example that such objects can be further developed using standard fractal techniques to create new, more complex designs that retain the perceptual illusion, sometimes allowing additional illusions to emerge from the process. The balanced Pytha...
متن کاملSelfsimilar Fractals and Selfsimilar Random Fractals
We survey the application of contraction mapping argments to selfsimilar (nonrandom) fractal sets, measures and functions. We review the results for selfsimilar random fractal sets and measures and show how the method and extensions also work for selfsimilar random fractal functions.

Therefore, the CAPM cannot be consistent with efficient frontiers for...

Correspondingly, the idea that words that express quotidian, middle-level concepts have complex representations "at the semantic level" is recurrent in linguistics; it is the defining thesis of what is of...
متن کاملInterruption Impossible
Most current work on spoken human-computer interaction has so far concentrated on interactions between a single user and a dialogue system. The advent of ideas of the computer or dialogue system as a conversational partner in a group of humans, for example within the CHIL-project and elsewhere (e.g. Kirchhoff & Ostendorf, 2003), introduces new requirements on the capabilities of the dialogue sy...
