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.

Desenvolvimento de um exoesqueleto para movimentação/reabilita-ção de paraplégicos

People bedridden by paralysis/motor disability are subject to several problems due to lack of movement. Then, it is necessary to use equipments that enable the people bedridden stand up and walk, so as to reduce the problems due to lack of movement and the time of rehabilitation, impacting directly on its quality of life. The aim of this work is the development of an exoskeleton to make the movement of people with paralysis / motor impairment in the lower limbs, without help of third parties, to be activated by the user. To provide support, stability and security to the deficient, it was decided to use a structure formed by four legs, being each leg consisting of a parallel chain. The gait was obtained by combining the movement of two mechanisms: crank/rocker, responsible for oscillatory motion of the leg, and cam/follower, responsible for the foot motion on the desired trajectory. To achieve the aim of this work was conducted a study about the types of exoskeletons for locomotion/rehabilitation of people with lower limb paralysis and presented a study on the movement of the lower limb joints. It also presented a mathematical model to obtain the desired path to the foot of the exoskeleton, the static model and the design of the structure elements. In the sequence is presented the simulation of movements of a people during the human gait, experimental tests and the comparison with the human gait developed by a people without disabilities.
