PVDF-PAni blend: a free-standing film with variable electrical resistance
(Springer, 2017-05-01)
Films made of a blend of polyaniline (PAni) and a nonpolar polyvinylidene fluoride (PVDF) polymer matrix were obtained by the mechanical mixing of both, with subsequent melting and quenching. Using the current versus voltage ...
Mutual coupling modeling in transmission lines directly in the phase domain
(2011-12-12)
This paper describes a computational model based on lumped elements for the mutual coupling between phases in three-phase transmission lines without the explicit use of modal transformation matrices. The self and mutual ...
