1. Effects of resistance training protocols on nonlinear analysis of heart rate variability in metabolic syndrome
Despite the various standard non-linear measurements used in autonomic modulation (AM) assessments usually being applied to long time-series, such analyses can sometimes be applied to shorter term series. To overcome this disadvantage, chaotic global methods were formulated by putting together heart rate variability (HRV) linear methods. Chaos provides infor

2. Power Allocation in PON-OCDMA with Improved Chaos Particle Swarm Optimization
Abstract In this work, it is investigated an improved chaos particle swarm optimization (IC-PSO) scheme to refine the quality of the algorithm solutions regarding to solve the optimal power allocation in next generation passive optical networks (NG-PON)s. The proposed IC-PSO scheme utilizes the Beta distribution instead of uniform distribution of the traditi

3. Doce ou atroz, manso ou feroz‖: os currículos realizados/inventados na relação com a(s) diferença(s) no cotidiano escolar
It was from the understanding of the ephemeral, the uncertainty and complexity that this dissertation was built. It is the result of my inquiries before the school and the difference(s) among students. I intended to dip in school life (re)visiting teaching practices embodied in the curricula made/invented various forms of questioning to be/seem/to be of the

4. Lavando a Alma: análise do contexto de uma sala de aula de língua inglesa de escola pública sob a luz da teoria do caos/complexidade. / Letting It All Out:analyzing an English classroom context in a state school based on chaos/complexity theory.
This research is an ethnographic case study that analyzes, in a descriptive form, the English language lessons in a second year high school classroom in a state school in the city of Goiânia. For this, we conducted a participant-observation research study, which, according to Spradley (1980), occurs when the researcher observes what happens in the research

5. O jogo de futebol : investigação de sua estrutura, de seus modelos e da inteligencia de jogo, do ponto de vista da complexidade / The soccer game ; : searche of this structure, its models and intelligence of the game from the point of view of complexity
In high-level sports, small things make difference between the first and second positions. The game, and in this is case the soccer game, is a complex phenomenon where the player s performance is transdimensional. At every time players and teams meet problem-situations, in unpredictable circumstances that need fast technical, tactical, physical and psycholog

6. Simulation, analysis and computational characterization of fingering patterns in fluids displacement on porous media. / Simulação, análise e caracterização computacional de padrões de fingering em deslocamentos de fluidos em meios porosos
In this work, the patterns related to the displacement process of an interface between two ftuids of different mobilities are studied computationally. In the literature, the formation process of these patterns is known as fingering, a type of dynamic instability in the interface between two miscible fluids, where the fingers are classified in two types: dens

7. A dinâmica caleidoscópica do processo de aprendizagem coloborativa no contexto virtual:: um estudo na perspectiva da complexidade/caos
In recent years there has been significant amoung of research guided by completxity and chaos theories in the area of Applied linguistics (Larsen-Freeman, 1997; Paiva, 2005; van Lier, 2004, Lantolf, 2006, Cameron and Deignan, 2006, among others). The ideas of complexity/chaos consider the inter-relation of agents in a complex system is dynamic, non-linear, o

8. Perspesctivas da complexidade aplicadas à gestão de empresas. / Perspectives of complexity applied to management.
The present work explores how two general approaches of complexity - complexity sciences and complex thought - are influencing and may come to influence productive organizational systems management. An increase in publications relating Complexity to Management can be observed. By analyzing the content of international and Brazilian academic works, a decrease

9. Dinâmica oscilatória na eletrooxidação de etileno glicol / Oscillatory dynamics in the ethylene glycol electrooxidation reaction
In the present work were studied some nonlinear aspects of the catalytic oxidation of ethylene glycol (EG) on platinum electrodes in alkaline media (KOH). The systems dynamics was investigated by means of cyclic voltammetry, current and potential time series, and electrochemical impedance spectroscopy (EIS). The EIS results reveal the presence of a hidden ne

10. Bi-estabilidade óptica &condensação de Bose-Einstein de polaritons
Optical bistability e®ects (OB) are intrinsically related to the gain media non-linearities. In microcavities, this behavior is due to Kerr effect proportionate by polariton number, generated resonantly in strong -coupling regime, instead of the photon number. The sample was held in a cold-finger cryostat at a temperature of 10K and is constituted by two DB

12. Metapsicopatologia da psiquiatria: uma reflexão sobre o dualismo epistemológico da psiquiatria clínica entre a organogênese e a psicogênese dos transtornos mentais.
This doctoral thesis intends to analyze the main concepts of mental disease and the problematic relation between the organicism and the psychodinamism throughout the history of the psychopathologic ideas that came to constitute the scientific clinical psychiatry, from Philippe Pinel, in the beginning of XIX century, until the chaos of the no theoretical pret
