We present a tensor-based method to decompose a given set of multivariate functions into linear combinations of a set of multivariate functions of linear forms of the input variables. The method proceeds by forming a three-way array (tensor) by stacking Jacobian matrix evaluations of the function behind each other. It is shown that a blockterm decomposition of this tensor provides the necessary...

Acquiring vocabulary has always been recognized as a significant and challenging part of language learning process. In this study, the researcher examined the extent to which form recall of target lexical items by learners of English as a foreign language (EFL) is affected by a) repetition and b) by the type of target item; single words versus collocations. The treatment consisted of non-commun...

language teachers usually face issues regarding the most effective methods of teaching. teaching language to nonnative speakers of english involves certain problems and challenges at all levels of instruction. due to the unsatisfactory results of focus on forms and focus on meaning instructions and their inevitable inadequacies, focus on form instruction along with its multiple techniques are r...
