a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولDifferential Delayed Equations - Asymptotic Behavior of Solutions and Positive Solutions
Brief Summary of Basic Notions For a b R , ∈ , a b < , let ([ ] ) n C a b R , , be the Banach space of the continuous functions from the interval [ ] a b , into n R equipped with the supremum norm | ⋅ | . In the case 0 a r = − < , 0 b = , we shall denote this space as r C , that is, ([ 0] ) n r C C r R := − , , and put 0 sup ( ) r r σ φ φ σ − ≤ ≤ || || = | | for r C φ∈ . If R σ ∈ , 0 A ≥ and ([...
متن کاملA note on positive periodic solutions of delayed differential equations
We consider the existence of positive ω-periodic solutions for the periodic equation x (t) = a(t)e x(t) x(t) − λb(t)f (x(t − τ (t))), where a, b ∈ C (R, [0, ∞)) are ω-periodic, ω 0 a(t)dt > 0, ω 0 b(t)dt > 0, f ∈ C ([0, ∞), [0, ∞)), and f (u) > 0 for u > 0, τ (t) is a continuous ω-periodic function.
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولA coefficient inequality for a subclass of the Carathéodory functions defined using conical domains
For 0 ≤ k < ∞, let Ωk be the conical domain in the complex plane C defined by Ωk = {w ∈ C : w = u + iv, u2 > k2((u − 1)2 + v2), u > 0}. Let qk(z) be the Riemann map of U := {z ∈ C : |z| < 1} onto Ωk satisfying qk(0) = 1, q′k(0) > 0. Let P (qk) be the class of analytic functions h(z) subordinate in U to qk(z) and represented by h(z) = 1 + b1z + b2z + · · ·, (z ∈ U). Sharp estimates for |b2 − ub1...
