The objective of this Part II the paper on a novel feedback approach is that unifying all previous general models within single framework and obtaining new results. In order to pursue goal, we exploit multiple possibilities implementation generic three-terminal circuit (TTC) has be inserted in cut loop when cut-insertion theorem (CIT) applied for analysis network. We present based direct openin...

abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...

The previous cut-insertion theorem, defined for linear circuits and particular three-terminal (TTCs) to be inserted into the cut, is here extended any TTC and, in a simplified form, non-linear networks. may include dependent independent sources other passive and/or elements, together with remaining part of circuit, determines feedback loop which “transmission factors” T $$ ′ {T}^{\prime } can c...
