Introduction: Addiction has affected people's performance in many ways and endangered their own health and that of their community. The aim of this study was to determine the effect of “Cognitive-Behavioral Therapy” training on substance use feedback and general health of addicts in 2019. Methods: The present study was performed by quasi-experimental method with pre-test design, post-test with...
Introduction: Aging is a process in which physiological and psychological changes, especially cognitive changes, are observed. The aim of the present study was to determine the effectiveness of neuro-feedback on the alpha frequency band and beta frequency band at points (F3, F4) in the elderly with mild cognitive impairment. Methods: For this purpose, in this semi-experimental research, 30 peo...
abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...

this paper undertakes the synthesis of a logic-based switching h2/h∞ state-feedback controller for continuous-time lti singular perturbation systems. our solution achieves a minimum bound on the h2 performance level, while also satisfying the h∞ performance requirements. the proposed hybrid control scheme is based on a fuzzy supervisor managing the combination of two controllers. a convex lmi-b...
In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...
