this study was designed and conducted to find out if there is any significant relationship between iranian efl learners preferance for one of the three degrees of obtrusiveness in foreign language instruction (focus on form, forms and meaning) and their preferred experiential learing style. to collect the data two questionnaires were used. the first one on the degree of obtrusiveness and the se...

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
