Accurate computation of transient profiles along multiconductor transmission systems by means of the numerical laplace transform
(2014)
In this paper, transient internal profiles along multiconductor transmission lines are obtained from a model described in the q-s domain (spatial frequencyoral frequency). In such domain, the telegrapher equations of the ...

Uma proposta de metodologia da avaliação da eficiência de máquinas elétricas no setor industrial
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2016-06-13)
Energy efficiency has been a hot topic nowadays, especially in the operation of induction motors, which are the largest energy consumers. So it is natural to develop a tool for assessing the efficiency of induction machine ...
On the validity of difusional model in determination of electric transport parameters of semiconductor compound
In this work we have studied the variable range hopping as a predominant electronic transport mechanism for semiconductor materials used as absorbent layer in photovoltaic devices. Dark conductivity measurements were carried ...
