in this paper, a novel approach for control of the dc-dc buck converter in high-power and low-voltage applications is proposed. designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. it is clear that in high-power applications, parasitic elements of the converter may become comparable with...

The ability to learn from feedback is important for children’s adaptive behavior and school learning. Feedback has two main components, informative value and valence. How to disentangle these two components and what is the developmental neural correlates of using the informative value of feedback is still an open question. In this study, 23 children (7–10 years old) and 19 adults (19–22 years o...

A self-learning approach for optimal feedback gains finite-horizon nonlinear continuous time control systems is proposed and analysed. It relies on parameter dependent approximations to the value function obtained from a family of universal approximators. The cost functional training an approximate law incorporates two main features. First, it contains average over objective values parametrized...

BACKGROUND Various feedback characteristics have been suggested to positively influence student learning. It is not clear how these feedback characteristics contribute to students' perceived learning value of feedback in cultures classified low on the cultural dimension of individualism and high on power distance. This study was conducted to validate the influence of five feedback characteristi...

We implemented a post prescribing review and feedback program to investigate its effect on appropriateness of antimicrobial use and antimicrobial consumption rate.A pre-post interventional study conducted in internal ward of Imam Hossein teaching hospital. For nine months of intervention phase, medical file of all patients who received intravenous antibiotic were reviewed by a clinical ph...
