1. Análise de um compensador estático paralelo monofásico visando a melhoria do fator de potência / ANALYSIS OF A PARALLEL PHASE STATIC COMPENSATOR
Este trabalho consiste no desenvolvimento de um sistema de controle do fator de potência através da utilização de um filtro ativo paralelo. Para tal, o sistema de controle do filtro é composto por uma malha externa de tensão e uma malha interna de corrente, baseadas em controladores PI. Para o desenvolvimento do mesmo, observaram-se as aplicações dos

2. ROBUST VARIABLE STRUCTURE MODEL REFERENCE ADAPTIVE CONTROL APPLIED TO ACTIVE POWER FILTERS / CONTROLE ADAPTATIVO ROBUSTO DE ESTRUTURA VARIÁVEL POR MODELO DE REFERÊNCIA APLICADO A FILTROS ATIVOS DE POTÊNCIA
This works presents a Robust Variable Structure Model Reference Adaptive Control scheme denoted VSRMRAC. In this adaptive control strategy, each parameter of the control law is obtained by the sum of two other adaptive terms. One of them is associated with the RMRAC algorithm, while the other is composed of an adaptive gain rated by an approximated sign func

3. Determinação do conteúdo harmônico de corrente baseada em redes neurais artificiais para cargas não-lineares monofásicas / Determination of the current harmonic content based on artificial neural networks for single-phase non-linear loads
In this thesis artificial neural networks are employed in a novel approach to identifying harmonic components of the single-phase nonlinear load current, whose amplitudes and phase angles are subject to unpredictable changes in steady-state. An identified harmonics number is previously selected. These harmonics are present in the non-linear loads current of

4. Estudo eletromiografico do padrão de co-ativação do musculo esternocleidomastoideo em diferentes movimentos mandibulares
Although cervical muscles co-activation during jaw movements has been studied, this verification is stilllittle described in literature when are compared healthy subjects and patients with muscular dysfunction. The aim of this study was to verify by surface electromyography the bilateral co-activation of the sternocleidomastoid (SCM) muscle regarding to chew

5. Population analysis in a denitrifying sand filter: conventional and in situ identification of Paracoccus spp. in methanol-fed biofilms.
The microbial community of a denitrifying sand filter in a municipal wastewater treatment plant was examined by conventional and molecular techniques to identify the bacteria actively involved in the removal of nitrate. In this system, denitrification is carried out as the last step of water treatment by biofilms growing on quartz grains with methanol as a s
