1. A comparative evaluation of the efficacy of manual, magnetostrictive and piezoelectric ultrasonic instruments: an in vitro profilometric and SEM study
OBJECTIVES: The debridement of diseased root surface is usually performed by mechanical scaling and root planing using manual and power driven instruments. Many new designs in ultrasonic powered scaling tips have been developed. However, their effectiveness as compared to manual curettes has always been debatable. Thus, the objective of this in vitro study w

2. Projeto de transdutor de corrente elétrica para alta tensão com nova abordagem de detecção magnetostritiva e sensoriamento óptico, utilizando Terfenol-D e grade de Bragg em fibra óptica / High voltage electric current transducer project, with innovative approach for magnetostrictive modulation and optical sensing using Terfenol-D and fiber Bragg gratings
Os sensores a fibra óptica são imunes à interferência eletromagnética (EMI), eles são normalmente encontrados em ambientes eletricamente ruidosos, especialmente em linhas de transmissão de alta voltagem. Essa é a característica principal que faz desse tipo de sensores ideais para empresas de Energia Elétrica. Esse trabalho apresenta uma nova aborda

3. APLICAÇÃO DE MATERIAIS COM MAGNETOSTRICÇÃO GIGANTE EM SENSORES DE DESLOCAMENTO SEM CONTACTO / GIANT MAGNETOSTRICTIVE MATERIALS APPLIED TO CONTACTLESS DISPLACEMENT SENSORS
Magnetostriction is a property of ferromagnetic materials to deform in the presence of a magnetic field. Magnetostriction is an inherent property of magnetic materials, which is unchangeable with time. Materials exhibiting strains in the order of 10-3 are known as giant magnetostrictive materials (GMM).In this dissertation we study the application of these m
