Self-assessment and task-based assessment have recently attracted attention in language learning and testing contexts worldwide; however, little research has been carried out to document the link between these notions. The present research was an attempt to investigate the connection between task-free/task-based self-assessment and learners’ self-perceived communicative competence in speaking. ...

this paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. a novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. parameters of the fuzzy estimator are adapted to minimize the estimat...

In the second part of our paper, we address crystal nucleation in the metastable liquid miscibility region of eutectic systems that is always present, though experimentally often inaccessible. While this situation resembles the one seen in single component crystal nucleation in the presence of a metastable vapor-liquid critical point addressed in previous works, it is more complex because of th...

This study investigates the effect of homogeneous and heterogeneous peer interaction on the development of Iranian EFL learners’ writing skill. Sixty female students of TEFL participated in the study. The participants were divided into two groups based on their English proficiency test scores. The homogeneous group consisted of 14 participants paired with partners with similar English proficien...

Reinforcement learning has been successfully applied to several subtasks in the RoboCup simulated soccer domain. Keepaway is one such task. One notable success in the keepaway domain has been the application of SMDP Sarsa(λ) with tile-coding function approximation [9]. However, this success was achieved with the help of some significant task simplifications, including the delivery of complete, ...
