A renormalisation approach to excitable reaction-diffusion waves in fractal media [PDF]
Of fundamental importance to wave propagation in a wide range of physical phenomena is the structural geometry of the supporting medium. Recently, there have been several investigations on wave propagation in fractal media.

Sobre dimensões fractais de ambientes construídos e naturais
Neste estudo, a análise fractal é aplicada à avaliação da complexidade visual de edifícios históricos e ambientes naturais circundantes. A dimensão fractal e suas aproximações, encontradas via o método da contagem de caixas (“box-counting method”), são ...

Dimensionalidade fractal e invariância de escala em circuitos elétricos AC e linhas de transmissão [PDF]
Resumo A geometria fractal fascina pela capacidade de descrever formas geométricas complexas e que usualmente estão presentes no mundo real . A dimensão fractal ou de Hausdorff d é utilizada para descrever leis de invariância de escala, em que as funções

Fractal Models for SAR images [PDF]
In this thesis the modeling of SAR (Synthetic Aperture Radar) images of natural surfaces described via fractal models is dealt with. A complete theoretical forward model linking the parameters describing the scene observed by the sensor to the stochastic

A Finite Element Approach to Modelling Fractal Ultrasonic Transducers [PDF]
Piezoelectric ultrasonic transducers usually employ composite structures to improve their transmission and reception sensitivities. The geometry of the composite is regular with one dominant length scale and, since these are resonant devices, this ...
