Corpo, força e potência: Nietzsche e Spinoza no pensamento de Deleuze

This dissertation aims at showing the importance of the Nietzsche s and Spinoza s philosophy in Deleuze thought, about body, force, and potency concepts. The search starts from Deleuze texts around two authors of his inspiration, reaching understand in the plan of immanence of the relationship between concepts and the way life as ethics and political affirmation. The first goal is the concept of rhizome; propose by Deleuze in what manner to walk the ways traced by philosophers and at the same time to create self ways. The second chapter examines the body in Nietzsche as force s relations. Find to show the genesis of the force in its determination as relative quantity strong or weak, and as absolute quality active or reactive; and for other side the genesis of the force from two poles of the will to power affirmation or negation, examining the consequences for life and thought. In the third chapter explained the definitions of body in Spinoza. The body, in Spinoza, defines itself complex relation of movement and repose, velocity and slowness and by it s to affect and be affecter s power. Find to show understanding the mediums for to amplify the power of to exist or the potency of to act, in what manner ethics of to live. The fourth chapter makes one parallel between the war and the thought in the constitution of socials body and collectives agenciamientos, for understand in the fifth chapter the body as war s machine of the thought, from the relationship between nomad way life and war s machine showed in Tractate of Nomadologia. Wait like this to show the importance of the ethics and political thought than affirm the existence in the world through active force from that body s power.

Estudo comparativo de dois conversores Boost quadrático com comutação suave monochaveados para aplicação de rastreamento de máxima potência em sistemas fotovoltaicos

This paper makes a comparative study of two Soft Single Switched Quadratic Boost Converters (SSS1 and SSS2) focused on Maximum Power Point Tracking (MPPT) of a PV array using Perturb and Observe (P&O) algorithm. The proposed converters maintain the static gain characteristics and dynamics of the original converter with the advantage of considerably reducing the switching losses and Electromagnetic Interference (EMI). It is displayed the input voltage Quadratic Boost converter modeling; qualitative and quantitative analysis of soft switching converters, defining the operation principles, main waveforms, time intervals and the state variables in each operation steps, phase planes of resonant elements, static voltage gain expressions, analysis of voltage and current efforts in semiconductors and the operational curves at 200 W to 800 W. There are presented project of PI, PID and PID + Notch compensators for MPPT closed-loop system and resonant elements design. In order to analyze the operation of a complete photovoltaic system connected to the grid, it was chosen to simulate a three-phase inverter using the P-Q control theory of three-phase instantaneous power. Finally, the simulation results and experimental with the necessary comparative analysis of the proposed converters will be presented.
