این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولThe Hierarchy of Hamiltonians for a Restricted Class of Natanzon Potentials
In particular, there have been studies within Supersymmetric Quantum Mechanics formalism. Cooper et al, [6], for instance, investigated the relationship between shape invariance and exactly analytical solvable potentials and showed that the Natanzon potential is not shape invariant although it has analytical solutions for the associated Schr odinger equation. L evai et al, [7], have determined...
متن کاملPseudo-Hermiticity for a Class of Nondiagonalizable Hamiltonians
We give two characterization theorems for pseudo-Hermitian (possibly nondiagonalizable) Hamiltonians with a discrete spectrum that admit a block-diagonalization with finite-dimensional diagonal blocks. In particular, we prove that for such an operator H the following statements are equivalent. 1. H is pseudo-Hermitian; 2. The spectrum of H consists of real and/or complex-conjugate pairs of eige...
متن کاملErratum: Pseudo-hermiticity for a Class of Nondiagonalizable Hamiltonians
Theorem 2: Let H be as in Theorem 1 of Ref. [2]. Then H is pseudo-Hermitian if and only if it is Hermitian with respect to an inner product 〈〈 , 〉〉 that supports a positivesemidefinite basis [3] including the eigenvectors of H . In particular, for every eigenvector ψ of H , 〈〈ψ|ψ〉〉 ≥ 0; if the corresponding eigenvalue is real and nondefective (algebraic and geometric multiplicities are equal), ...
متن کاملState-to-state transition probabilities for time-dependent Hamiltonians using complex absorbing potentials
Abstract. Earlier work has derived a new expression for the time-independent scattering probability for time-dependent Hamiltonians for cases where the motion is free at infinitely large times. Here we introduce a new technique which provides an efficient numerical algorithm for the calculation of multiphoton event probabilities based on using complex absorbing potentials along the scattering c...
