This work presents a technique for electrical grounding system representation, directly in the time domain. It is based on the theory of least squares and starts from harmonic grounding impedance, representing it by discrete ...

Ground Potential Rise (GPR) is an important factor for a grounding system that must be properly designed to protect people against any dangerous induced voltages and to avoid damages in equipment. In this context, several ...

Facing the dynamics of the current competitive conditions involves the identification of phenomena related to the company’s development or intrapreneurship. With the purpose of contributing to a generation of theory in ...

Several years of total ozone measured from space by the ERS-2 GOME, the Earth Probe TOMS, and the ADEOS TOMS, are compared with high-quality ground-based observations associated with the Network for the Detection of ...

Backflashover is one of the mechanisms by which lightning strikes can cause outages/damages in power systems. In this context, the tower-footing grounding system of transmission towers has an essential role for mitigating ...

Grounding electrodes are used to provide a low-impedance dissipation path for the excess lightning or fault currents. Several studies have been dedicated to the computation of the grounding impedance of different electrode ...

Although interest in the use of grounded theory methods has been increasing over the last decade, Urquhart, Lehmann, and Myers (2010) take note of the criticism that, in fact, such use has not yet produced higher levels ...

Este trabalho consiste na proposta de utilização, em Odontologia, de uma abordagem metodológica usada em pesquisas qualitativas, denominada Grounded Theory, quando se objetiva compreender fenômenos ou se pretende descrevê-los ...
