The increasing complexity of information systems (ubiquitous systems, open enterprises, etc.) calls for the introduction of always new modeling languages.

This article deals with this issue by...

متن کاملImpossible fractals

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...
