27. CONTRIBUIÇÃO AO ESTUDO DAS PROPRIEDADES MECÂNICAS E DA DURABILIDADE DE CONCRETOS COM ESCÓRIA DE ACIARIA ELÉTRICA (EAF) COMO AGREGADO GRAÚDO / CONTRIBUTION TO THE STUDY OF MECHANICAL PROPERTIES AND THE DURABILITY OF CONCRETE WITH SLAG OF Residue (EAF) as aggregate
The increasing demand for aggregate for uses in engineering stimulated the search for alternative materials. In this way, the civil construction potentially started to be a great consumer of residues from other industries, becoming a great recycle plant. The use of by-product, brings great environmental benefits in relation to the degradation of the environm

28. Monitoramento permanente de motores de indução trifasicos / On-line monitoring of three-phase induction motors
A predictive maintenance program must include several techniques of monitoring of the electric motors conditions. Among these techniques, probably the two most classic ones are related to electric current and vibration analysis. Unfortunately, in both cases inherent drawbacks make difficult their use in loco on industry plants. As there is a large range of
