1. Estudo sobre sistemas de segurança em instalações elétricas automatizadas. / A study about security systems in automatized eletric installations.
This work presents a study of the main security systems used in automatized electric installations, with approach in the physical access control, using biometric technologies. The main characteristics of the security systems applied to the detection and fire combat, to the physical access control, to the internal and external security control, as closed-circ

2. Potencials and electric fields inside and outside resistive conductors carrying steady currents / Potenciais e campos eletricos dentro e fora de condutores resistivos com correntes constantes
In Chapter 1 we present an introduction about the electric field inside and outside resistive conductors carrying steady currents. We also discuss the distribution of surface charges that maintains the current fiow and its relation with these electric fields. We present some experiments related with these electric fields outside conductors with steady curren
