A user-friendly extrapolation method for computing infinite range integrals of products of oscillatory functions
where s is an arbitrary integer, φ̂(x) and θ̂ (x) are real polynomials in x , φ̂(x) ≡ 0 being possible, exp[φ̂(x)] is bounded at infinity and R(x) and gj (x) are smooth functions that have asymptotic expansions of the forms R(x) ∼ ∑∞ i=0 bi x −i and gj (x) ∼ ∑∞ i=0 c ± j i x δ j−i as x → ∞, with arbitrary and δ j . We denote the class of such functions by B̃(s). These integrals may converge or diver...
متن کاملThe Effect of User-Friendly Texts vs. Impersonal and Hybrid Texts on the Reading Comprehension Ability of Iranian EFL Learners
This study focuses on the effect of user-friendly, impersonal, and hybrid texts on the reading comprehension ability of Iranian foreign language learners. Forty-five students of AlzahraUniversity were selected on the basis of their performance in a recent TOEFL. They were given three different texts (each group of 15 students was given one type) describing the same area of English usage, w...
متن کاملSeismic Wave-Field Propagation Modelling using the Euler Method
Wave-field extrapolation based on solving the wave equation is an important step in seismic modeling and needs a high level of accuracy. It has been implemented through a various numerical methods such as finite difference method as the most popular and conventional one. Moreover, the main drawbacks of the finite difference method are the low level of accuracy and the numerical dispersion for l...
متن کاملA free user friendly program for evaluation of radiotherapy plans based on different dose response models
Introduction: Radiotherapy (RT) plan evaluation using dose response models has become a feasible approach in routine clinical practice. Although there are several tools for this task, they suffer from limitations including number of different dose response models and parameters. In the present study, we aimed to develop a free program for RT plan evaluation based on a variety ...
متن کاملA User-Friendly Extrapolation Method for Oscillatory Infinite Integrals
In a recent publication [4] the author developed an extrapolation method, the ^-transformation, for the accurate computation of convergent oscillatory infinite integrals. In yet another publication [6] this method was shown to be applicable to divergent oscillatory infinite integrals that are defined in the sense of summability. The application of the VK-transformation involves some asymptotic ...
