Comparison of PIM and the Variational Iteration Methods (VIM) for Solving Linear Optimal Control Problems

Comparison of PIM and the Variational Iteration Methods (VIM) for Solving Linear Optimal Control Problems

This article presents the Parametric Iteration Method (PIM) for finding optimal control and its corresponding trajectory of linear systems. Without any discretization or transformation, PIM provides a sequence of functions which converges to the exact solution of problem. Our emphasis will be on an auxiliary parameter which directly affects on the rate of convergence. Comparison of PIM and the Variational Iteration Method (VIM) is given to show the preference of PIM over VIM. Numerical results ...

Comparison of Energy Levels of F Isotope(91) using OXBASH Shell Model Code with Experimental Results

Comparison of Energy Levels of F Isotope(91) using OXBASH Shell Model Code with Experimental Results

In this work by using OXBASH shell model code is calculated of energy levels of F isotopes. This code which is based on one of the most applicable nuclear models, deals with evaluating energy levels. Meanwhile, the ground state of excitation energy evaluated by OXBASH code together with energy levels and also probable places for nucleons rsquo; placements in each energy level. Programs will be reliable only when results meet experimental procedures.Key Words:Energy Levels-Shell Model-OXBASH ...

Foreign Language Vocabulary Retention: Investigating the Role of T-Coding Method in Comparison with Rote Rehearsal Learning

Foreign Language Vocabulary Retention: Investigating the Role of T-Coding Method in Comparison with Rote Rehearsal Learning

English as Foreign Language (EFL) learners frequently encounter difficulties in applying disparate strategies or techniques in order to recall the unfamiliar vocabularies. Language learners use vocabulary as a mean of reception and expression to acquire and convey meaning. Therefore, being able to remember new and unfamiliar words is outstanding for their success. Allen (1999) states that ldquo;vocabulary instruction is one of those educational arenas in which research and best practice are ...
