1. Modelagem e Controle de Conversores Fonte de Tensão Utilizados em Sistemas de Geração Fotovoltaicos Conectados á Rede Elétrica de Distribuição
Esta dissertação apresenta uma estratégia de controle para sistemas de geração fotovoltaicos, de único estágio, trifásicos, conectados á rede elétrica de distribuição. São desenvolvidos modelos matemáticos para representar as características dinâmicas dos painéis fotovoltaicos, do conversor fonte de tensão (VSC - Voltage Source Converter")

2. Vector control of a single-phase induction motor / Controle vetorial do motor de indução monofásico
The objective of this work is to study the rotor flux vector control applied to a single-phase induction motor drive. Initially, a mathematical model of the motor will be derived. The motor equations will be transformed to the stationary reference frame so that the angular dependency due to the asymmetry of the motor variables is eliminated. Then is discusse

3. Recursos de linguagem na animação: a enunciação cinematográfica construida a partir das transformações da figuratividade quadro a quadro / Resources of animation language: the cinematographic enunciation constructed on frame by frame figurativeness transformation
Definition of issue and objectives: This work aims to identify and review some of the resources of animation movies, determined by its specific production processes with several subjects, frame by frame, that recognises it as a special form of cinematographic language. Which are the specificities of cinematographic enunciation that are intrinsic to the frame

4. Optokinetic stimulation influences the disturbed perception of body orientation in spatial neglect.
The effect of optokinetic stimulation on the disturbed perception of body orientation in three patients with right brain damage and spatial neglect was examined. The patients were asked to direct a laser point to the position which they felt lay exactly "straight ahead" of their bodies' orientation. Without stimulation they localised the body's sagittal midp

5. Seeing the hand while reaching speeds up on-line responses to a sudden change in target position
Goal-directed movements are executed under the permanent supervision of the central nervous system, which continuously processes sensory afferents and triggers on-line corrections if movement accuracy seems to be compromised. For arm reaching movements, visual information about the hand plays an important role in this supervision, notably improving reaching
