as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...
A set of well known necessary conditions for the existence of a large set of t-designs, LS[N ](t, k, v), is N ∣∣∣(v−i k−i) for i = 0, . . . , t. We investigate the existence of large sets of size four. We take advantages of the recursive and direct constructions to show that the trivial necessary conditions are sufficient when N = 4, t = 2, 3 and k ≤ 7.
we investigate the existence of some large sets of size nine. the large set $ls[9](2,5,29)$ is constructed and existence of the family $ls[9](2,5,27l+j)$ for $lgeq 1, 2leq j
A set of necessary conditions for existence of a large set of a t-design, LS ( (v−t k−t ) /n; t, k, v ) , is n| (v−i k−i ) for i = 0, 1, · · · , t. We show that these conditions are sufficient for n = 3, t = 2, 3, or 4, and k ≤ 8.
A large set of t-(v, k, λ) designs of size N , denoted by LS[N ](t, k, v), is a partition of all k-subsets of a v-set into N disjoint t-(v, k, λ) designs, where N = ( v−t k−t ) /λ. A set of trivial necessary conditions for the existence of an LS[N ](t, k, v) is N ∣
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
معادلات انتگرال دیفرانسیل در مدل بندی مسائلی کاربردی چون انتقال گرما، پدیده انتشار و پخش نوترون مورد استفاده قرار می گیرند و نیز در برخی کاربردهای فیزیک و زیست شناسی و مهندسی استفاده وافر دارند و به تبع آن معادلات انتگرال دیفرانسیل فازی نیز مورد توجه قرار گرفته اند. معادله انتگرال دیفرانسیل غیر خطی زیر را در نظر می گیریم. در صورتی که توابع معلوم a(t)و k(t,s,x(t)) و f(t,x(t)) توابعی ف...
recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
