Fractal curves and complexity.
Fractal curves were generated on square initiators and rated in terms of complexity by eight viewers. The stimuli differed in fractional dimension, recursion, and number of segments in their generators. Across six stimulus sets, recursion accounted for most of the variance in complexity judgments, but among stimuli with the most recursive depth, fractal dimension was a respectable predictor. Si...
متن کاملDeveloping fractal curves
Many fractal curves can be produced as the limit of a sequence of polygonal curves, where the curves are generated via an iterative process, for example an L-system. One can visualise such a sequences of curves as an animation that steps through the sequence. A small part of the curve at one step of the iteration is close to a corresponding part of the curve at the previous step, and so it is n...
متن کاملTangents to fractal curves and surfaces⋆
The aim of our work is to specify and develop a geometric modeler, based on the formalism of iterated function systems with the following objectives: access to a new universe of original, various, aesthetic shapes, modeling of conventional shapes (smooth surfaces, solids) and unconventional shapes (rough surfaces, porous solids) by defining and controlling the relief (surface state) and lacunar...
متن کاملFractal analysis of thermoregulatory complexity
Blessing and Ootsuka present in this issue of Temperature a cogent treatment of the analytical and conceptual pitfalls of 2 heavy hitters in physiology and behavior: the concept of homeostasis and the concept that most biobehavioral outcomes of a rhythmical nature are intrinsically sinusoidal and thus imbued with predictable periodicity. These conventions, the authors argue, fail to take into a...
متن کاملFractal complexity of EEG signal
The paper deals with the presence of exponential or power-law decay in the power spectra of electroencephalogram (EEG). About 2300 EEG time series recorded during relaxed wakefulness were analysed. The whole spectrum of EEG was studied and power-law decay of about 2.28 prevailing over the exponential falling off was established. Correspondence between spectrum power-law decay and correlation di...
