building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
After all the processing elements have the initial w value, each processing element can do the compare to determine which is smaller. Then the problem can be reduced to a sum. If the compare is successful, the processor will store a 1, and 0 otherwise. Then the sum is done on the set of 1’s and 0’s throughout the hypercube. The dimension order is simply the reverse of the original broadcast. Fi...
and Applied Analysis 3 otherwise [H A (x, s(t))] i = x i , where b i ∈ R is the threshold of neuron i and the function 1 is the Heaviside function: 1(u) = 1 for u ≥ 0, otherwise 0, which describes an instantaneous unit pulse. On each subsequent time t = 0, 1, . . ., the network generates a vector of neuronal active states according to (8), resulting in the dynamic flow x(t), t = 0, 1, . . .. Th...

In the article [17] we consider only the case when n and m are non-negative integer points determined by: n ≥ 1 is the multiplicity of the root x = a, otherwise n = 0 if x = a is not the root; and m ≥ 1 is the multiplicity of the root x = b, otherwise m = 0 if x = b is not the root. In this case, if for the function f(x) at the point x = a there is an approximation of the function by Taylor pol...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
به طور کلی در فرآیندهای مارکوف ارگودیک دو بعدی یافتن فرم بسته توزیع ایستا، تنها برای حالات خیلی خاص امکان پذیر است. با توجه به این مشکل و نیز با توجه به اهمیت توزیع ایستا، بررسی و مطالعه رفتار مجانبی توزیع ایستای این فرآیندها مورد توجه قرار گرفته است. زنجیر قدم زدن تصادفی دو بعدی که در برخی متون به آن، فرآیند qbd دو طرفه نیز می گویند، یکی از این فرآیندها است. یک فرآیند qbd زمان گسسته یک زنجیر م...
