Abstract: Several recent papers have shown the ability of iterated function system (IFS) models to represent discrete sequences where the attractor of an IFS is self-affine either in R/sup 2/ or R/sup ...

Historically, the reason(s) why cultural number systems vary in their structure and organization has been unclear, especially for models seeking answers within the brain. Here a simple explanation is ...

in layered media can be expressed as an infinite series in terms of the spectral domain Green's functions. The discrete complex image method (DCIM) can be used to approximate these spectral domain ...
