in this research at the first enalapril drug and its fullerene derivative were optimized. nbo calculations and nmr for the complexes were carried out at the b3lyp/6-31g* quantum chemistry level. different parameters such as energy levels, the amount of chemical shift in different atoms, the amount of homo/lumo, chemical potential (µ ), chemical hardness (η), the coefficients of hybrid bonds (π,...

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

Let t=t1t2⋯ be an element of the full shift with map τ on a finite alphabet symbols A and let Σ=closure{τi(t):i∈N∪{0}}. ft=ft1,∞=⋯∘ft2∘ft1 non-autonomous system over compact metric space X where ti∈A. The set Ft+={fτi(t):i∈N} is called shifted family ft. If t transitive in AN, then Ft+‾ classical IFS; otherwise, Σ subshift Ft+‾={fσ=fσ1,∞:σ∈Σ} “generalized” IFS. We show that if ft has some shado...

The σ -convergence and σ -core of a real bounded sequence were introduced in [R. Raimi, Invariant means and invariant matrix methods of summability, Duke Math. J. 30 (1963) 81–94] and [S.L. Mishra, B. Satapathy, N. Rath, Invariant means and σ -core, J. Indian Math. Soc. 60 (1984) 151–158], respectively. In this work, we extend these ideas to double sequences. c © 2006 Elsevier Ltd.
