13. Mapeamento do potencial mineral para niquel e ouro no Cinturão Metassedimentar Nova Brasilandia - Rondonia por meio de logica nebulosa (fuzzi) e redes neurais artificiais / Mineral potential mapping for nickel and gold in Nova Brasilandia Metassedimentar Belt - Rondonia trough fuzzy logic and artificial neuraL networks
Analysis and integration of spatial data from different natures, particularly on Geographic Information Systems (GIS), is a well known technique in mineral prospection. The available tools and other ones recently developed can help prospection campaigns where there is not enough geologic and metalogenetic knowledge, as the Nova Brasilândia Metassedimentar B

14. Estudo de Fractalidade e Evolução Dinâmica de Sistemas Complexos
In this work, the study of some complex systems is done with use of two distinct procedures. In the first part, we have studied the usage of Wavelet transform on analysis and characterization of (multi)fractal time series. We have test the reliability of Wavelet Transform Modulus Maxima method (WTMM) in respect to the multifractal formalism, trough the calcu

15. Design of high-speed networks considering monofractal and multifractal traffic models.
Fractal traffic models capture uniquely statistical scaling characteristics and the burstiness of the real network traffic. The impact of such traffic models on existing networks has been studied extensively in the related literature and the relevance of such analysis to dimension the necessary resources and evaluate correctly the performance of these system

16. Métodos emergentes de física-estatística aplicados a séries temporais
The main objective of the present work was to apply recently developed in methods in physics-statistics to the time series, especifically in this work, to intervals of heart beats obtained from blood pressure signs (BP) of the sloth (Bradypus variegatus), with the purpose of identifying differences in fractality terms in the system of autonomous control rela

17. Aspectos especiais e temporais do problema do enovelamento protÃico
The manner in which a protein folds from a random coil into a unique native state in a relatively short time is one of the fundamental puzzles of molecular biophysics. It is well accepted that a unique native three-dimensional structure, characteristic of each protein and determined by the sequence of its amino-acids, dictates protein functions. In this Thes

18. Fractal dynamics in physiology: Alterations with disease and aging
According to classical concepts of physiologic control, healthy systems are self-regulated to reduce variability and maintain physiologic constancy. Contrary to the predictions of homeostasis, however, the output of a wide variety of systems, such as the normal human heartbeat, fluctuates in a complex manner, even under resting conditions. Scaling techniques
